Explosion-proof instrument air integrated gas supply system

Abstract

The invention discloses an explosion-proof instrument air integrated gas supply system. The system comprises a mounting box, a first air compressor is mounted on one side of the left end of the mounting box, a second air compressor is mounted on the other side of the left end of the mounting box, and the edge side of the first air compressor is fixedly connected with one end of a first connectingpipe. The explosion-proof instrument air integrated gas supply system is convenient to use and reliable and can also ensure heat dissipation of the whole system, and then a circuit of the whole systemis isolated from the surrounding environment, so that heat generated by the circuit during normal work and electric sparks and high temperature formed in a fault state are limited in a sealed shell,surrounding flammable and explosive gas is prevented from being ignited, and rapid compression of air is achieved; an alarm can be given when the system is powered off or the voltage is low; and whenone programmable PLC is damaged, another programmable PLC can be connected into the system, so that normal operation of the system is ensured, and then processing efficiency of the gas is ensured.

Description

technical field [0001] The invention relates to the technical field of gas processing equipment, in particular to an explosion-proof instrument air integrated gas supply system. Background technique [0002] After the natural gas is filtered by the air filter of the compressor unit, it is sucked into the screw compressor host, compressed, and discharged into the primary storage tank for storage and pressure regulation, after preliminary cooling and preliminary dehydration. After filtering through the secondary pipeline filter, it enters the adsorption dryer for deep water removal, and then enters the tertiary pipeline filter and deodorizing activated carbon filter to remove the remaining extremely small amount of impurities such as water, oil, dust, peculiar smell, etc., and obtain clean compressed air. Then store it in a secondary stainless steel storage tank. At this time, the quality standard of the compressed air is about dust content less than or equal to 0.01 micron, o...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide an explosion-proof instrument air integrated gas supply system to solve the problem that the inside of the existing breathing integrated system box is connected with the outside world in the above-mentioned background technology, which is easily affected by the surrounding flammable and explosive gas. Ignition greatly reduces the safety of the entire system during use, and the entire system is controlled by a single PLC. When there is a problem with the PLC, the entire system will not be able to operate, which greatly reduces the problem of gas processing efficiency.
