Abstract
A tail gas reflux device, namely a sterilizing gas detector, relates to a gas detection device. The tail gas reflux device can reduce the loss of the sterilizing gas concentration and ensure the quality of sterilizing, has higher detection accuracy and can prolong the service life of the sensor of the detection instrument and ensure personal health and security of the sterilizing workers. The tail gas reflux device is provided with a reflux pipe, a first gas guide pipe, a getter pump, a second gas guide pipe and a one-way air valve, wherein pores are arranged at the front end of the reflux pipe; the rear end of the reflux pipe is connected with the gas inlet of the getter pump by the first gas guide pipe; a handle is arranged in the position where the reflux pipe is connected with the first gas guide pipe; and the two ends of the second gas guide pipe are respectively connected with the gas outlet of the getter pump and the gas inlet of the one-way air valve.
Description
Technical field
The present invention relates to a kind of gas-detecting device, especially relate to a kind of tail gas reflux device, namely sterilizing gas detector.
Background technology
In the stifling processing procedure of various facilities, generally must carry out gas concentration and detect, detect data and be and judge the stifling whether qualified unique index of handling.In existing gas concentration testing process, tail gas is directly to be discharged in the atmosphere, and this way not only causes loss to fumigating gas concentration in the stifling confined space, and hazard detection staff's health of human body.
Notification number provides a kind of portable light interfere type to be exclusively used in the detector of phosphine gas for the utility model patent of CN2039844.This device is mainly become with the gas circuit set of systems by the optical system that is assembled on the housing.It is on the basis of existing optical interferometry structure, is improved and makes.The length of critical component-air chamber wherein, design according to the refractive index of phosphine gas and the difference of measurement range thereof, simultaneously the reading drum of optical system and the full scale scale value of graticule are changed accordingly, it is not only easy to operate, value is directly perceived, accurately, and can solve silo stifling during the quantitative measurement of phosphine gas concentration.
Summary of the invention
The object of the present invention is to provide a kind of loss that reduces fumigating gas concentration, guarantee stifling work quality, accuracy in detection is higher, can prolong the serviceable life of detecting instrument sensor, guarantees the tail gas reflux device, namely sterilizing gas detector of stifling staff's health of human body safety.
The present invention is provided with recirculatory pipe, the 1st wireway, asepwirator pump, the 2nd wireway and Non-return air valve, front end at recirculatory pipe is provided with pore, rear end the 1st wireway of recirculatory pipe is connected with the air intake opening of asepwirator pump, be provided with handle at recirculatory pipe and the 1st wireway junction, the two ends of the 2nd wireway are connected with the gas outlet of asepwirator pump and the air intake opening of Non-return air valve respectively.
Described recirculatory pipe can adopt stainless-steel tube.The described front end that is provided with the recirculatory pipe of pore preferably is pointed.Described the 1st wireway and the 2nd wireway can be rubber tube.Rear end the 1st wireway of described recirculatory pipe is connected with the air intake opening of asepwirator pump, and preferably the rear end of recirculatory pipe and the 1st wireway are spirally connected.
Compare with existing fumigating gas detector, the present invention has following outstanding advantage:
1) owing to fumigating concentration can be detected the gas of sampling, therefore blowback has reduced the loss of fumigating gas concentration to stifling confined space, has guaranteed stifling work quality.
2) owing to be provided with Non-return air valve in the present invention, can prevent gas backstreaming, not influence detection numerical value, therefore not only can guarantee to detect data more accurately, truly, reliably; And the influence that can avoid fumigating gas that the detecting instrument sensor is caused, the serviceable life of prolongation detecting instrument sensor.
3) owing to increased pressure, can therefore can guarantee stifling staff's health of human body safety with the residual blowback of the toxic gas in the detecting instrument wireway to stifling confined space.
