Abstract

The invention discloses a VOC tank cleaning instrument, and relates to a device for cleaning the interior of a container and creating a vacuum environment. The VOC tank cleaning instrument comprises a machine case, wherein a seven-inch screen is arranged on the side edge of the machine case, a main control circuit board is arranged in the machine case and connected with a controller, the controller is connected with a pressure sensor, the pressure sensor is connected with a four-position four-way valve, the four-position four-way valve is connected with a plurality of SilcoCans through SilcoCan connecting pipes and hoops, the four-position four-way valve is respectively connected with a nitrogen cylinder and a three-position three-way valve with a pressure sensor through two two-way electromagnetic valves, and the three-position three-way valve is connected with a turbine pump. According to the invention, the VOC tank cleaning instrument is reasonable in structural design, has leakage detection and cleaning functions, and is simple to operate, convenient and reliable to use and high in practicability.

Description

technical field [0001] The invention relates to a device for cleaning and creating a vacuum environment in a container, in particular to a VOC tank cleaner. Background technique [0002] The US EPA's TO-14 / TO-15 method for determining VOC in ambient air includes collecting air samples with "SUMMA" electrolytic polishing sampling tanks, and then analyzing them with GC. This method provides guidance on how to decontaminate and test sampling canisters by measuring residual VOC concentrations after decontamination. Therefore, the importance of fully and correctly cleaning the sampling canister before using it cannot be ignored. [0003] However, the current sampling tank cleaning instrument has a single function, is inconvenient to carry, and cannot detect the air tightness of the sampling tank and the gas circuit, that is, it is impossible to check whether there is an air leak, which will cause sample leakage and pollution due to the air leak. [0004] In summary, the present...
