AI Technical Summary
Existing chemical reactors are prone to contaminating or catalyzing reaction products under high temperature and pressure. Quartz tubes are not pressure resistant and cannot be used in high-pressure environments.
A reactor was designed that combines a quartz inner liner with a metal reactor body. By injecting reaction gas at the same pressure into the gap between the inner liner and the inner wall of the reactor body, the pressure inside and outside the inner liner is balanced, preventing reaction products from entering the gap. Combined with a heating furnace and sealing ring design, high-pressure operation is achieved.
Effective isolation of reaction products from the metal wall prevents contamination and catalytic effects, ensures normal operation of the reactor under high pressure, and avoids adverse reactions.

Description
TECHNICAL FIELD
[0001] The utility model relates to a reactor suitable for experimental device and can be used in high pressure environment belongs to chemical reaction technical field. BACKGROUND
[0002] Chemical reactor is mostly metal material, and for some special reactions, metal material can cause pollution to reaction product under high temperature or can cause catalysis to non-ideal reaction. Therefore, it is required to line the metal reactor with isolation material to prevent the above-mentioned situation from happening. The isolation material generally adopts quartz material, which is resistant to high temperature, but the quartz tube is not resistant to pressure and can only be used under normal pressure. Especially when exploring experiments are carried out on experimental devices, it is required to line the reactor with quartz from time to time, and the reaction is carried out under certain temperature and pressure. Therefore, it is very necessary to design a reactor suitable for high pressure environment. SUMMARY
[0003] The utility model solves the technical problem that: provide a kind of reactor suitable for experimental device can be used under high pressure.
[0004] In order to solve the above problems, the utility model provides a kind of reactor suitable for high pressure environment, it includes reactor cylinder body, the top, bottom of reactor cylinder body is equipped with reaction cylinder body upper flange, reaction cylinder body lower flange, reaction cylinder body upper flange, reaction cylinder body lower flange is respectively matched with reactor upper head flange, reactor lower head flange, reactor upper head flange is equipped with feed inlet, and reactor lower head flange is equipped with discharge port;Reactor cylinder body is equipped with inner lining cylinder in, and the top of inner lining cylinder is equipped with inner lining cylinder upper flange, and inner lining cylinder upper flange is equipped between reactor upper head flange, reaction cylinder body upper flange, and the upper part of reactor cylinder body is equipped with reaction gas injection hole.
[0005] Preferably, the upper part of the reactor cylinder body is symmetrically provided with reaction gas injection holes. Under the control of flow, trace amount of reaction raw gas with the same pressure in the reactor is continuously injected, so that the inner and outer walls of the inner lining cylinder are balanced under pressure, while ensuring that the reaction product does not enter the gap between the inner lining cylinder and the inner surface of the reactor cylinder body, causing adverse reactions. Since the normal effluent in the reactor also contains part of the unconverted reaction raw gas, the trace amount of reaction gas injected will not affect the product properties and will be discharged from the reactor together with the reaction product.
[0006] Preferably, the reaction gas injection hole is communicated with the reaction gas through a pipeline.
[0007] More preferably, a hand valve is provided on the pipeline.
[0008] More preferably, a control valve and a reaction gas injection flowmeter are provided on the pipeline. The injection of trace amount of reaction raw gas can be automatically controlled, and the flow can be monitored and manually adjusted.
[0009] Preferably, a gap is provided between the inner lining cylinder and the inner wall of the reactor cylinder to accommodate thermal expansion of the metal.
[0010] Preferably, the outer portion of the reactor cylinder is provided with a heating electric furnace and a thermal insulation layer.
[0011] Preferably, an upper flange of the inner lining cylinder is provided with an upper sealing ring and a lower sealing ring between the upper flange of the reactor and the upper flange of the reactor cylinder, respectively. The upper flange of the inner lining cylinder and the upper flange of the reactor and the upper flange of the reactor cylinder form a double sealing, so that the reactor is suitable for operation under high pressure.
[0012] Preferably, the bottom of the inner lining cylinder is an open structure extending to the lower flange of the reactor cylinder, ensuring that the entire high temperature zone is covered by the inner lining cylinder.
[0013] Preferably, the material of the reactor cylinder is metal.
[0014] Preferably, the material of the inner lining cylinder is quartz. Since the metal material of the reactor causes pollution to the reaction product or catalyzes non-ideal reactions, the above problems will not occur when the reaction product flows out of the catalyst bed and the temperature decreases to a certain temperature. Therefore, the reactor must be long enough to ensure that the product has reached the temperature required when it reaches the outlet.
[0015] In the high temperature reaction zone, the inner lining cylinder completely isolates the reactants from the metal reactor wall, preventing the metal material of the reactor from causing pollution to the reaction product or catalyzing non-ideal reactions. The gap formed between the inner lining cylinder and the inner wall of the reactor cylinder is injected with reaction gas at the same pressure as the reactor, so that the inner lining cylinder is balanced in pressure. This special design allows the reactor to be used under high pressure, while ensuring that the reaction product does not enter the gap and cause adverse reactions. The open design of the lower end of the inner lining cylinder balances the pressure inside and outside the inner lining cylinder, allowing the reactor to be used under high pressure and eliminating the problem of the inner lining cylinder not being able to withstand pressure.
