Description

Technical Field

[0001] This utility model relates to a detachable salt bath jacket suitable for experimental reactors, belonging to the field of chemical heat exchange technology. Background Technology

[0002] Reactors are a crucial type of reactor in chemical testing equipment. Heating methods include directly heating the outer wall of the reactor with an electric furnace or heating jacket, or indirectly heating the reactor by installing a salt bath jacket and then heating the salt bath jacket with an electric furnace. While direct heating with an electric furnace is simple and easy to manufacture, the strong radiant heat from the heating element at high temperatures can easily cause coking of the material in contact with the inner wall of the reactor. This is particularly true for materials prone to coking, such as coal tar, kerosene slurry, and petroleum residue, where coking has already occurred during high-temperature testing. Installing a salt bath jacket on the outside of the reactor, using high-temperature molten salt to heat the reactor wall, avoids the strong radiant heat of the heater and significantly reduces the tendency of the test material to coke. However, for high-temperature, high-pressure reactors, directly welding the salt bath jacket to the reactor body raises concerns among equipment manufacturers that welding may cause unpredictable damage to the reactor body, affecting its pressure resistance and potentially leading to hazards during use. Therefore, developing a detachable salt bath jacket that does not require welding to the reactor body is essential to ensure safe operation of the reactor under harsh conditions. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a detachable salt bath jacket suitable for a test apparatus reactor.

[0004] To address the aforementioned problems, this utility model provides a detachable reaction vessel salt bath jacket, comprising a salt bath jacket disposed outside the reaction vessel, a salt bath heater disposed outside the salt bath jacket, a quick-opening flange disposed at the top of the salt bath jacket, the inner edge of the quick-opening flange being limited at a support boss at the outer edge of the reaction vessel, the outer edge of the quick-opening flange being provided with an inner hook, and the top of the salt bath jacket being provided with an outwardly extending outer edge, the inner hook of the outer edge of the quick-opening flange extending to the bottom of the outer edge of the top of the salt bath jacket.

[0005] Preferably, the width of the support boss is 1-2 mm. The distance between the support boss and the body flange of the reactor should be as small as possible, but it should be ensured that the quick-opening flange can be easily installed.

[0006] Preferably, the distance between the inner wall of the salt bath jacket and the outer wall of the reactor is 20-50 mm.

[0007] Preferably, the inner wall of the top opening of the salt bath jacket is provided with multiple support rods evenly distributed along the cross-section of the inner wall, and the support rods do not contact the outer wall of the reactor.

[0008] More preferably, the inner wall of the top opening of the salt bath jacket is provided with three support rods evenly distributed along the cross-section of the inner wall.

[0009] Preferably, the top outward extension of the salt bath jacket extends 5-15 mm beyond the outer wall of the salt bath jacket.

[0010] Preferably, the quick-opening flange is divided into two parts, each with a quick-opening flange locking lug at both ends. Adjacent quick-opening flange locking lugs are connected by locking bolts and locking nuts. The opening formed between adjacent quick-opening flange locking lugs serves as a salt inlet or an insertion port for a salt bath thermocouple. During installation, the inner edge of the quick-opening flange is pressed tightly against the outer wall of the reactor above the supporting boss. The thickness of the quick-opening flange must be sufficient to prevent deformation under the weight of the supporting salt bath jacket.

[0011] Preferably, the width of the salt inlet is 20-30 mm.

[0012] Preferably, the quick-opening flange is tightly fitted against the outer wall of the reactor.

[0013] Preferably, the width of the inner hook on the outer edge of the quick-opening flange is 10-20mm.

[0014] This invention avoids directly welding the salt bath jacket to the reactor body, thus preventing unforeseen damage to the reactor body that may be caused by welding operations. It does not affect the pressure resistance of the reactor and ensures that the reactor can still be used safely under harsh conditions. Attached Figure Description
