把好反应釜防火设计关

作者:admin    访问量:1782    发布时间:2016-05-26

反应釜设备泄漏等引发火灾的主要原因往往起源于设计阶段,因此抓好设计阶段的防火工作十分重要。首先是反应釜的设计、选型、选材、布置及安装均应符合国家规范和标准。严格把好设计关,根据不同工艺过程的特点,选用相应的耐高温或低温、耐腐蚀、满足压力要求的材质,采用先进技术进行制造和安装,做好严格的防火审核工作,并通过严格的试车和验收。

The main cause of the fire caused by the leakage of equipment is often originated from the design stage, so it is very important to do a good job of fire prevention work in the design stage. First, the design, type selection, material selection, installation and installation of the reactor should be in accordance with national standards and standards. Strictly control the design, according to the characteristics of different processes, selection of appropriate resistance to high or low temperature, corrosion resistance, to meet the pressure requirement of material, adoption of advanced technology for manufacture and installation, do a good job strict inspection of fire prevention work, and through the strict test and acceptance.

对化工生产行业的从业人员要相对稳定,加强职工的工艺和操作纪律,制定并严格执行操作规程。提高职工业务素质水平和生产操作技能。制定事故应急预案,进行演练,提高职工事故状态下的应变能力。

To the chemical industry's employees to be relatively stable, to strengthen the process of workers and operational discipline, to develop and strictly enforce the rules of operation. Improve the level of staff's professional quality and production operation skills. Formulate contingency plans, conduct drills to improve the emergency response capacity of workers.

常见的在生产中广泛使用并取得良好效果的有:

(1)阻火设备。它包括安全液封、水封井、阻火器、单向阀、阻火阀等,其作用是防止火焰闯入反应釜设备、管道或阻止火焰在其间扩展。

(2)防爆泄压设备。包括安全阀、爆破片(防爆片)、放空管等,安装于压力容器、管道等生产设备上,起降压防爆作用。

(3)火星熄灭器。安装于产生火星的设备和装置,防止火星飞出引燃可燃物。

(4)自动探测器。用于检测可燃气体浓度、温度。

Widely used in production and achieved good results are:

(1) fire resistance equipment. It includes safety liquid seal, seal well, flame arrester, a one-way valve, a flame retardant valve, and its role is to prevent the flame into the reaction kettle(www.wfanyingfu.com) equipment, pipes, or prevent flame propagation in the meantime.

(2) explosion proof pressure relief equipment. Including safety valve and bursting disc (explosion), vent pipe installed on the pressure vessels, pipelines and other production equipment, explosion-proof step-down role.

(3) Mars goes out. Installed on the equipment and devices have Mars, prevent Mars flying out of the ignition of combustible materials.

(4) automatic detector. Used to detect the concentration of combustible gas, temperature.
