Multi-gas supply system of workshop gas supply station

Abstract

The invention belongs to the technical field of factory gas supply systems, and particularly relates to a multi-gas supply system of a workshop gas supply station. The multi-gas supply system comprises a gas supply device, a conveying device and a control device, the gas supply device is communicated with the conveying device which comprises a pipe, a pressure adjusting valve, a gas inlet, a gas outlet and an air exhausting device; the control device comprises a monitor, a lightning protection device and a propane alarming device; an oxygen and argon supply device comprises a low-temperature storage tank, a vaporizer, a pressure adjusting valve, a mixed gas matching cabinet and a buffer tank; a welding mixed gas supply device comprises a low-temperature storage tank, a vaporizer, a pressure adjusting valve, a mixed gas matching cabinet and a flowmeter; a propane gas supply device comprises a busbar, an automatic switching device, a gasification device and a gas-liquid separation device; a compressed air supply device comprises an air compressor, a drier, a filter and a gas storage tank. By means of the technical scheme, multiple gases can be supplied to a factory for use; meanwhile, whole-process monitoring can be achieved. Total supply safety of the gas supply system is achieved.

Description

technical field [0001] The invention belongs to the technical field of factory gas supply systems, in particular to a multi-gas supply system for workshop gas supply stations. Background technique [0002] At present, the industrial gas required by the production plants mainly in the processing industry is relatively large and has many types. The gas pressure is 15MPa gas, and the gas pressure is high pressure, which is extremely dangerous. Explosions happen from time to time. At present, some factories use steel cylinders for gas supply, which have small capacity, heavy weight, frequent pressure control, high transportation costs, and low efficiency. After the gas in the cylinder is used up, it cannot be replenished in time, and the processing equipment needs to be suspended, and then restarted after the cylinder is replaced. The efficiency of this gas supply method is extremely low, and it is not suitable for heating and continuous production equipment. In view of the a...

Problems solved by technology

[0003] The problem to be solved by the present invention is that the centralized gas supply device in the existing factory has a simple structure and cannot supply multiple groups of gas at the same time, and at the same time cannot centrally control
