Problems solved by technology

[0003] At present, the use of air bags is very large, and there is waste and secondary pollution. One sample uses one air bag
Because the air bag cannot be cleaned after the sample is collected, the air bag can only be used once and then discarded, causing pollution to the environment itself, and also wasteful from an economic point of view

experiment Embodiment 1

[0054] The 16 1L air bags to be tested and cleaned contain acetone gas with nitrogen as the medium, and the concentrations are 1ppm, 5ppm, 10ppm, and 20ppm. Acetone, as a common chemical reagent, is often used in the production process of chemical industry and electronics. , whose characteristics are water-soluble compounds.

[0055] First set the conditions: cleaning and inflating a cycle time: 1 minute

[0056] Heater temperature: 80 degrees

[0057] Number of cleaning cycles: 3

[0058] The following operation stages are only for the convenience of understanding the embodiment of the present invention, and the sequence of operations does not constitute the necessary steps of the cleaning method of the air bag.

[0059] 1. Pumping stage

[0060] (1) The air outlet solenoid valve 8 is opened by the controller 11, the air pump 9 works, and the gas in the heater 4, the air bag, and the 12-position gas distributor 5 is sucked away.

[0061] (2) The suction force of the air p...

experiment Embodiment 2

[0078] The 16 1L air bags to be tested and cleaned contain benzene gas with nitrogen as the medium, and the concentrations are 1ppm, 5ppm, 10ppm, and 20ppm. As a common chemical reagent, benzene is often used in the production of chemical industry, electronics, and pesticides. in process. It is very toxic and is a major carcinogen.

[0079] Set conditions:

[0080] Cleaning and inflation cycle time: 1 minute

[0081] Heater temperature: 80 degrees

[0082] Number of cleaning cycles: 3

[0083] Basically, the same operation steps as in Experimental Example 1 are adopted, and details are not repeated here.

[0084] After the cleaning is completed, pour 500ml of clean nitrogen into the air bags with different concentrations of 1ppm, 5ppm, 10ppm, and 20ppm, and analyze the concentrations and residues by using a mass spectrometer according to the standard method of environmental standard HJ734, as shown in the following table:

Abstract

The invention discloses a gas bag cleaning device and method. The gas bag cleaning device comprises a fixing device, an inflating device and a gas pumping device, wherein the fixing device is providedwith a gas distributor and gas connectors of gas bags, the gas distributor is connected with the gas connectors through pipelines, the gas distributor is connected with the two or more pipelines, each pipeline corresponds to the corresponding gas connector, and the gas connectors are mutually connected; the inflating device is connected with the gas distributor through a pipeline so as to fill the gas bags with gas through the gas connectors; and the gas pumping device is connected with the fixing device through a pipeline and used for pumping out gas in the gas bags and the fixing device. The gas bags in the market can be cleaned through the gas bag cleaning device and method and thus can be recycled. In this way, consumption of the gas bags in the analyzing and sampling processes can bereduced, the cost is saved, and the situation that the gas bags become secondarily polluted solid pollutants can also be avoided as much as possible.

Description

【Technical field】 [0001] The invention belongs to the field of gas detection equipment, and in particular relates to an air bag cleaning device and an air bag cleaning method. 【Background technique】 [0002] Gas bags are widely used in China as gas sampling methods, and gas analysis projects are increasingly valued by various industries, especially the sampling of volatile organic compounds in waste gas from fixed pollution sources must be collected by air bags. [0003] At present, the use of air bags is very large, and there is waste and secondary pollution. One sample uses one air bag. Because the air bag cannot be cleaned after the sample is collected, the air bag can only be used once and then discarded, which pollutes the environment itself and is wasteful from an economic point of view. 【Content of invention】 [0004] The invention provides an air bag cleaning device and an air bag cleaning method, so that the air bag can be used repeatedly after cleaning. [0005...
