Washing system for washing U-shaped porous glass plate absorption tube

Abstract

The invention discloses a washing system for washing a U-shaped porous glass plate absorption tube. The washing system comprises the U-shaped porous glass plate absorption tube, a flow guide system, aliquid supplying and collecting system and a peristaltic pump; the flow guide system and the U-shaped porous glass plate absorption tube communicate with each other to form a mutually-communicating liquid guide passage loop; a clean water supply device, a washing acidic liquid supply device and a waste liquid recycling device of the liquid supplying and collecting system separately communicate with the liquid guide passage loop formed by communication of the flow guide system and the U-shaped porous glass plate absorption tube; different liquid guide loops are formed by opening and closing control of each control valve on the liquid guide passage loop, the clean water supply device, the washing acidic liquid supply device and the waste liquid recycling device, so that the washing system disclosed by the invention has various different washing modes. The washing system disclosed by the invention is simple in structure, reasonable in design, simple to operate and control, simplified inwashing procedures, short in washing period and capable of washing the substances which are left or precipitated and adsorbed on the inner wall of the U-shaped porous glass plate absorption tube morecompletely.

Description

technical field [0001] The invention relates to a cycle cleaning system, in particular to a cleaning system for cleaning U-shaped porous glass plate absorption pipes in environmental monitoring projects. Background technique [0002] With the rapid development of modern industry, a large amount of excessive discharge of industrial waste gas seriously endangers the living environment of human beings. In order to avoid the impact of atmospheric environmental pollution on people's health, people pay more and more attention to gas detection in environmental monitoring projects. The U-shaped porous glass plate absorption tube is a commonly used instrument bottle for the determination of environmental gas pollutants. It is mainly used to collect common gases such as sulfur dioxide, nitrogen oxides, ammonia, formaldehyde, and fluoride; for example, in the People's Republic of China The document of environmental protection standard HJ 479-2009 mentions the use of U-shaped porous gla...

AI Technical Summary

Problems solved by technology

Therefore, the cleaning operation of the U-shaped porous glass plate absorption tube is usually very troublesome, especially in the experiment that many U-shaped porous glass plate absorption tubes are used, so the experimenter needs to clean the U-shaped porous glass plate absorption tube for a long time. Wasted a lot of time and manpower
