Embodiment 1

[0016] in such as figure 1 In the device, the bursting disc (3) and the fusible plug (2) are installed on the wall of the reactor (1), and it is characterized in that the bursting disc (3) and the fusible plug (2) respectively pass through the pipeline in parallel It is connected with the pressure relief pipeline (5), and the other end of the pressure relief pipeline (5) is connected with the buffer container, and the pressure relief pipeline (5) is provided with a control valve (4).

[0017] The bursting disc (3) is a positive arched bursting disc, and the fusible plug (2) has a tapered hole on the plug body to fill the fusible alloy. The fusible alloy is made of bismuth, lead, tin and cadmium, etc. Alloys made of metal elements with low melting points. The melting point of the fusible alloy can be achieved by adjusting the content of low-melting metal elements according to the critical temperature that may lead to overheating. When the temperature in the reactor (1) reache...

Embodiment 2

[0019] According to the conditions described in Example 1, only the bursting disc (3) is a reverse arched bursting disc, and the plug body of the fusible plug (2) has stepped holes.

Abstract

The invention relates to a temperature-sensing pressure-sensing anti-explosion device. By adoption of the temperature-sensing pressure-sensing anti-explosion device, the problems of low safety coefficient and pollution to the environment in the prior art are mainly solved. The temperature-sensing pressure-sensing anti-explosion device comprises a fusible plug (2) containing a fusible alloy, an explosion disc (3), a control valve (4), a pressure releasing pipeline (5) and a buffering container (6), wherein the explosion disc (3) and the fusible plug (2) are arranged on the wall of a reactor (1), and are respectively connected with the pressure releasing pipeline (5) by pipelines in a parallel mode; and the other end of the pressure releasing pipeline (5) is connected with the buffering container (6). By adoption of the technical scheme, the problems are relatively well solved, and the temperature-sensing pressure-sensing anti-explosion device can be used for achieving the anti-explosion purpose of the container.

Description

technical field [0001] The invention relates to a temperature-sensitive and pressure-sensitive explosion-proof device. Background technique [0002] Reactor is one of the common equipment in petroleum, petrochemical, chemical and coal chemical industries, which produces the required products from certain raw materials through chemical reactions. Many chemical reactions are exothermic, resulting in an increase in the temperature and pressure of the reaction system. Temperature and pressure are the main parameters of the reaction system. Once there is a problem with raw material feeding, cooling system, etc., when the heat release rate is greater than the heat transfer rate, the reaction is prone to runaway, causing the reaction to overheat, which in turn leads to a sharp increase in the temperature and pressure of the reaction system. The pressure rises sharply and cannot be effectively controlled, causing the pressure to exceed a certain range, resulting in damage to the n...
