Abstract
The invention discloses a method for recycling emptying residual gas of high purity gas transportation and storage tank. The method is used for recycling residual gas and residual liquid which need to be decompressed in a mobile storage tank of raw materials including liquid nitrogen, liquid argon and liquid oxygen for high purity nitrogen, argon and oxygen during transportation and handling. Before the mobile storage tank is refilled with liquid raw materials, the gas releasing valve of the mobile storage tank is connected with an air heating type vaporizer through a high pressure hose, a recycling system is formed by organically connecting a gas tank filling system with the connected gas releasing valve and the air heating type vaporizer; the residual gas and the residual liquid which originally need to be emptied before filling of liquid nitrogen, liquid argon and liquid oxygen are recycled by a gas compressor and are used for filling high pressure gas tank groups, thereby achieving the purpose of recycling the discharged gas of high purity nitrogen, argon and oxygen liquid transportation and storage tank; and the cost of liquid raw materials of high purity nitrogen, argon and oxygen can be saved by about 5%.
Description
Technical field
The invention belongs to industrial gas power-saving technology, be specifically related to a kind of method that originally need to rush down the residual air of pressure, the recycling of remaining liquid to high-purity high pure nitrogen, argon gas, oxygen feed liquid nitrogen, liquid argon, liquid oxygen in transportation, cargo handling process in portable storage tank.
Background technique
High pure nitrogen, argon gas, oxygen are purposes gas very widely in industrial production.In air, after separated liquefaction, in entering minute process of assembling, with liquid state, transported, stored before this.
And high-purity liquid nitrogen, liquid argon, liquid oxygen transportation storage tank are mainly used for the instrument of liquid nitrogen, argon gas, oxygen transportation.Its transportation has following flow process to form: high-purity liquid nitrogen, liquid argon, liquid oxygen transportation storage tank Kong Fen producer fill before liquid nitrogen, liquid argon, liquid oxygen, owing to filling the needs of technique, liquid or the residual air of the institute in tank case must being had a surplus is all rushed down to be pressed onto and is approached normal pressure and can fill.Manufacturer fill full after, be transported to that gas is used or gas divides and fills producer.High-purity liquid nitrogen, liquid argon, liquid oxygen transportation storage tank are when unloading liquid nitrogen, argon gas, oxygen, owing to also having quite high pressure in the fixed liquid nitrogen of the object of unloading, liquid argon, liquid oxygen storage tank, therefore cannot make the liquids and gases that transport in storage tank all unsnatch, the amount generally having more than 5% has been stayed in transportation storage tank, in Qu Kong subsidiary factory again, return home and fill before high-purity liquid nitrogen, nearly all residual air all must be rushed down to be pressed onto and approach normal pressure, cause very large waste.
Summary of the invention
Goal of the invention of the present invention is in order to overcome the shortcoming of above-mentioned background technology, a kind of recovery method is provided, by the high pressure spring connecting tube for air temperature type vaporizer of high-purity liquid nitrogen, liquid argon, liquid oxygen transportation storage tank and existing high pure nitrogen, argon gas, oxygen charging system, increase a membrane compressor, transportation storage tank unsnatch raw material liquid nitrogen, liquid argon, liquid oxygen again Qu Kongfen producer fill before high-purity liquid nitrogen, liquid argon, liquid oxygen, all residual air is recovered in high pure nitrogen, argon gas, oxygen cylinder, thereby reaches the object of 5% left and right that economizes in raw materials.
Technological scheme of the present invention is: a kind of method that high-purity gas transportation emptying storage tank residual air is recycled, and the method comprises following step:
(1) collecting pipe valve connects: at high-purity gas transportation storage tank, unsnatch raw material and again fill before liquid material, liquid valve on storage tank is connected with the air temperature type vaporizer liquid-inlet in original high-purity gas charging system with high pressure hose, completes the collection of bleed off high-purity gas;
(2) vaporization of the remaining liquid of bleed off: the gas outlet of air temperature type vaporizer is connected with the entrance of gas buffer tank, the liquid gas that has of gas reservoir bleed off is thoroughly vaporized by air temperature type vaporizer, enter knock out drum;
(3) compression of high-purity gas: knock out drum is connected with the import of gas compressor, and the former high-purity gas of outlet of compressor fills a bottle group and is connected, completes the front task that fills that reclaims;
(4) compression fills: compressor fills bottle group to high-purity gas to carry out pressurized gas and fill.
Described collection pipe valve is stainless steel spring pressure tube, and pressure can bear below 2.0MPa.
Described compression fills and adopts membrane compressor to carry out, and the pressure of compressor is 20.0MPa to the maximum.
The invention has the beneficial effects as follows: utilize method of the present invention, only need to be by high pure nitrogen, argon gas, oxygen liquid transporting be connected with high pressure hose with the air temperature type vaporizer of general industry gas filling, in the situation that increasing a diaphragm type compression, just the recycling of emptying residual air may be realized, high pure nitrogen, argon gas, the liquid cost of material of oxygen 5% left and right can be saved.
