Temperature-pressure dual-control explosion suppression device and petrochemical industry safety reaction device

Abstract

The invention provides a temperature-pressure dual-control explosion suppression device, comprising an explosion suppression storage tank, a pressure control trigger, and a temperature control trigger, wherein the pressure control trigger and the temperature control trigger are arranged on the explosion suppression storage tank. According to the invention, the device has good whole performance, can realize dual explosion suppression control of pressure and temperature, increases the safety of the reaction device; the physical temperature control trigger has the advantages of low cost, good stability, low failure rate, etc., and the explosion accidents of devices that only use pressure to conduct explosion suppression caused by malfunctions of electric control apparatus, fault of decompression valve, etc. are eliminated.

Description

technical field [0001] The invention relates to an explosion suppression device, in particular to a temperature and pressure dual control explosion suppression device. Background technique [0002] In the development process of the petrochemical industry, the explosion of the reactor or reactor has always been a major safety problem that must be faced at any time in the production process. How to suppress the explosion of the reactor is an important issue in the safe production of petrochemical industry. Explosive device is an important safety device. Most of the traditional explosive suppression devices use pressure as a sign to trigger the operation of the explosive suppression device, so as to control the work of the explosive suppression device. The explosion suppression device is generally equipped with a pressure sensor. When the pressure sensor detects that the pressure is abnormal and higher than the set value, it will touch the container containing the inert gas, fi...

Problems solved by technology

The pressure fluctuation is strong, if the detection value is set high, it may cause the explosion suppression system to start slowly; if the detection value is set low, the explosion suppression system may start when it should not be activated. Therefore, its sensitivity is poor and it is difficult to detect , the failure rate is relatively high, which has seriously affected the application of the explosion suppression device in the explosion suppression process of the reactor. On this basis, the present invention has found through research that the increase in pressure is often based on the increase in temperature, and the temperature has higher pressure than the pressure. More sensitive, easier to detect, more stable, and low failure rate. Therefore, it is proposed to use dual control of temperature and pressure to suppress the explosion device, but no special pressure and temperature dual control explosion suppression device has been seen so far.
