During the manufacturing process of the glass-lined reactor, a large amount of internal stress is generated due to reeling, stamping and welding. If these stresses are removed by heat treatment before the glaze is melted, the number of times of simmering is reduced, thereby ensuring the bismuth glass reaction. The working efficiency of the kettle is as follows: 1. The thickness of the porcelain layer of the glass-lined reactor is 0.8-2mm, and the number of simmering should be 5-7 times. In the production process, the number of burns is reduced and the thickness of each glaze is increased. 2. The stress generated during the equipment manufacturing process is not only released by annealing, but also placed for at least 15 days after the equipment is burned. The finished equipment will not explode during the static period before leaving the factory. 3. In order to make up for the pinholes and porcelain defects in the porcelain layer produced during the production process, the glaze cannot be sprayed repeatedly, resulting in serious equipment deformation. In addition, after the glass-lined reactor penetrates into the corrosive liquid on the lid or the heat-conducting medium becomes acidic, hydrogen gas is generated, and a part of the hydrogen atoms diffuse into the holes in the holes. The metal is combined there. Hydrogen molecules will make the enamel in the kettle thin, and cannot accelerate the consumption of tooth enamel to increase the working speed. As one of the commonly used pressure vessel equipment in the chemical industry, glass-lined reactors have been recognized more and more, but even the equipment needs to be properly used and maintained. 1. Remember to use glass, especially under high temperature conditions, for certain strong acids and alkalis. 2. Always pay attention to the abnormal vibration and sound of the glass-lined reactor. If a malfunction is found, it should be inspected and repaired in time and the malfunction should be eliminated. 3. During the operation of glass-lined reactors, strictly implement operating procedures and prohibit over-temperature and over-pressure. 4. Avoid the superposition of the stress caused by the temperature difference of the glass-lined reactor and the stress of the internal pressure, which may cause strain on the glass-lined equipment. 5. The reaction material in the reactor should be strictly controlled in its composition ratio to prevent violent chemical reactions caused by the imbalance of the ratio. 6. Control the temperature of the jacket (or coil) and some other reactors according to the process specifications of the reactor. The production environment of some glass-lined reactor manufacturers is poor, and the anti-rust and dust-proof standards do not meet the standards, resulting in poor adhesion between the bottom glaze and the substrate. Some reduce the number of simmering times, increase the thickness of each layer, make the internal force too large, and affect the service life of the glass-lined kettle. Therefore, the quality of the glass-lined kettle can be ensured in strict accordance with the manufacturing regulations.

With the increase in applications and the popularization of production technology, the types of enamel reactors are becoming more and more abundant, and now tailor-made services are basically realized. So what are the precautions in the specification of the reactor? The editor will analyze it for everyone:   1. Should the reactor model specifications be specified when purchasing? 2. Two specific aspects, the specifications of the enamel reactor and the model of the glass-lined reactor, should be paid attention to during the purchase process. Because they are important aspects that will affect the correct choice of the reactor, they must be clear, so the answer to this question It's for sure.   3. Are there any important technical parameters on the enamel reactor? Also, what is the diameter of a 3000L glass-lined reactor? The glass-lined reactor has some important technical parameters, as well as some important parameters, such as the specifications of the glass-lined reactor. Therefore, the answer to question 1 is yes. The 3000L glass-lined reactor generally has a diameter of 1.6m. But it depends on the actual situation.   4.10L, 20L, 30L, enamel reactor specifications?   Glass-lined reactor specifications are not 10L, 20L, 30L, because the current lower limit of the glass-lined reactor specifications is 50L, so this conclusion can be drawn. Furthermore, referring to GB25025, there are no three specifications.   5. Enamel reactor, its specification is 3000L, then, what is its overall height?   If the specification of the reactor is 3000L, then its overall height is generally about 2.85 meters. But for different manufacturers, their specific values ​​may be different, but the difference is not big. So I hope everyone can have a clear understanding and understanding of this point.   The above points clearly introduce some requirements on the specifications of the enamel reactor. If you have any other questions or problems, you can contact us directly. If you want to know more, please continue to pay attention to us.

When the glass-lined reactor is first bought, the equipment will be damaged due to improper operation. Various problems will occur during use and for a long time. For customers who often use glass-lined reactors, the most worrying thing is There is a problem and we are very concerned about repairing and repairing methods. Let's take a look at the possible problems and repairs in use.   1, processing stress damage   During the processing of the kettle body, a large amount of internal stress is generated due to the reel, stamping, and welding. If these stresses are not completely eliminated, the glass-lined kettle will explode. This kind of damage often occurs in the first three months after being put into use, so heat treatment or aging treatment on the embryo body can prevent the porcelain from exploding.   2, mechanical damage   Glass-lined glass has poor impact resistance, and metal impact on it will cause the enamel to break. Therefore, strictly prevent any metal during the use of the glass-lined kettle. In case of blockage, plastic rods must be used to dredge the pot, and the pot cover must be covered during maintenance to prevent small pits or explosions on the porcelain surface when the welding slag is melted.   3, external force   When handling the glass-lined reactor, only the ears of the tank are allowed to be subjected to force (when it is not packaged). Rolling and crowbars are not allowed to avoid vibration and collision. It is strictly forbidden to take over the force of vulnerable parts such as pipe hoops and clamps.   Under conditions, the equipment is best stored indoors. When the equipment is stored outdoors, it should be covered to avoid people knocking, sun and rain. When storing in winter, special attention should be paid to checking the tank and thermometer casing for water accumulation to avoid damage due to freezing. For reaction tanks or polymerization kettles equipped with mechanical seals, the sealed parts should be protected and kept clean.   4, working temperature influence   The glass-lined reactor is fired at a high temperature of 900℃, and the glass-lined and steel plate are bonded together after cooling. Since the linear expansion coefficient and elongation of the glass lined are smaller than that of the steel plate, the deformation of the glass lined after cooling is smaller than the deformation of the steel plate, and the glass lined is restrained by the steel plate to generate compressive stress. After the glass lined kettle is made, the glass lined has pre-compression stress, while the steel plate has pre-tension stress.   Because the prestress is related to the coefficient of linear expansion and elongation, and the coefficient of linear expansion and elongation are closely related to the temperature, the working temperature of the glass-lined kettle has a great influence on the use of the glass-lined kettle. If the stress generated by the glass lined exceeds its service stress due to a large temperature change, the glass lined will be destroyed. Therefore, the glass-lined kettle can explode when exposed to cold and heat.   Too much difference between the material temperature and the temperature of the kettle body during feeding, and excessive steam and rapid cooling can also cause porcelain explosion. Therefore, the glass-lined kettle should be slowly and evenly raised and lowered in use, and cooled in stages.   5, hydrogen evolution corrosion The jacket of the glass-lined kettle will scale and rust after a period of use. If an acidic detergent is used to remove the dirt or the coolant in the jacket is acidic, it will cause the metal to undergo hydrogen evolution corrosion. It can't diffuse outward, so when H2 accumulates to a certain degree and forms a certain power, the glass lined will break. Therefore, when pickling is used for cleaning and scaling, a buffer must be added. If the value of the glass-lined kettle is high or it is not easy to replace or even corrosive perforations occur, a high-quality cleaning agent with low corrosion rate must be used to avoid improper cleaning operations. Serious consequences.   6. Poor enamel quality   Some glass-lined reactor manufacturers have poor production environment and fail to meet the standards for rust and dust removal, resulting in poor bonding between the base glaze and the substrate. Some reduce the number of enamel firing times and increase the thickness of each layer, so that the internal force is too large and affects the service life of the glass-lined kettle. Therefore, the quality of the glass-lined kettle can be ensured by manufacturing strictly in accordance with the manufacturing regulations.   7, the base material is unqualified In order to reduce costs, some manufacturers use Q235 steel as a substitute for the embryo body, which directly causes the carbon and sulfur in the steel to vaporize during the enamelling process, causing a large number of bubbles to form between the glass-lined layer and the substrat

The filling of the glass-lined reactor must be carried out correctly, so as to better ensure the normal operation of the reactor equipment. Then again, what kind of effect does the packing have on the reactor equipment? We together look.   1. The passing capacity of the packing: the ultimate passing capacity of the packing is the gas velocity of the empty tower at the flooding point.   2, the efficiency of the filler: the factors that affect the efficiency are more complicated, but it is more reliable to design according to the actual test value.   3. The material of the filler: firstly, it should be determined according to the corrosiveness of the materials processed by the glass-lined reactor and the operating temperature.   4. The pressure drop of the packing: the power consumption mainly depends on the total pressure drop of the whole tower in the gas phase.   5. Packing size: The appropriate ratio of the diameter to the outer diameter of the packing has a lower limit. When the diameter ratio is lower than this value, it is difficult to predict their performance.   So from the above content, it can be seen that the filler is a very critical operation for the glass-lined reactor, which can help you better operate and use the equipment. So everyone must learn more about other information about the device, so as to better master the use of the device.
