Temperature control device of high-pressure bottle filling system

Abstract

The invention belongs to the technical field of gas filling, and particularly relates to a temperature control device of a high-pressure bottle filling system. The device comprises a product gas inputpipeline connected with an air separation system, the product gas input pipeline is connected with an air inlet of a high-pressure compressor, an air outlet of the high-pressure compressor is connected with a product gas output pipeline, a high-pressure cooler is arranged on the product gas output pipeline, a tube shell medium of the high-pressure cooler is a cooling medium, the tube pass mediumis a gas channel, the tail end of the product gas output pipeline is connected with a filling system body, the cooling medium is water cooling unit constant temperature control circular cooling water,and the filling system body is a cylinder manifold connected with multiple high-pressure bottles. According to the temperature control device of the high-pressure bottle filling system, after the high-pressure bottles are filled, standing pressure is not changed, the customer satisfaction degree is improved, and the economic losses brought by sales return can be reduced.

Description

technical field [0001] The invention belongs to the technical field of gas filling, in particular to a temperature control device for a high-pressure bottle filling system. Background technique [0002] Existing air separation cylinder gas distribution systems generally use external compression filling, that is, the qualified low-pressure product gas of the air separation tower is boosted by a compressor, and then filled into steel cylinders through the bus bar after the boost. Due to the high temperature of the environment and gas source, the compressed gas in summer causes a difference of about 2Mpa between the pressure of the gas in the compressed high-pressure cylinder and the pressure of the gas before standing. Customers often complain about the insufficient pressure of the gas cylinder, not only for The reputation of the company will be affected, and economic losses such as transportation costs will be incurred due to the return of the goods. [0003] Since the compr...

Due to the high temperature of the environment and gas source, the compressed gas in summer causes a difference of about 2Mpa between the pressure of the gas in the compressed high-pressure cylinder and the pressure of the gas before the static. Customers often complain about the insufficient pressure of the gas cylinder, not only for The reputation of the company will be affected, and economic losses such as transportation costs will be incurred due to the return of the goods.
