Embodiment 1：
With reference to shown in accompanying drawing 1, a kind of device for preventing from welding toxic gas diffusion, including housing 1, it is characterised in that institute
The equipment cavity 3 and closed reaction chamber 2 being divided into housing 1 for installing pumping filter plant are stated, the reaction chamber 2 passes through air inlet
Pressure check valve is installed in pipe 22 and atmosphere and air inlet pipe 22, the reaction chamber 2 is interior to be also equipped with heater 21 and contain
Equipped with the water for flooding heater 21；Air exhauster 31 is installed, the suction end of the air exhauster 31 is by pumping in the equipment cavity 3
Pipe 32 is connected with reaction chamber 2.
What deserves to be explained is, due to the species difference using its pernicious gas for producing of different welding procedures, so, contain
It is molten that water in reaction chamber can be replaced by the reaction with more preferable neutralization for produced poisonous, pernicious gas
Liquid, therefore this it will become apparent to those skilled in the art that, detailed description is not just enumerated herein.
Operation principle：
When in use, one end port that air inlet pipe 22 stretches out reaction chamber is placed in welding region, opens air exhauster 31,
Under the air-extraction function of air exhauster 31, the pressure in reaction chamber 2 is gradually reduced, and certain negative pressure is formed in air inlet pipe 22, when
When pressure differential reaches the rated pressure difference of the check valve being arranged in air inlet pipe 22, the free end that gas rushes in tracheae 22 enters into
In reaction chamber 22, reaction is carried out by the reaction solution or water that are contained in reaction chamber 2 and is filtered through exhaust tube 32 to discharge.
When the welding material selected can produce the gas for being unfavorable for neutralization reaction at normal temperatures in welding process, can be with
Heater 21 is opened, reaction solution or water are heated, further, catalyst can added in solution and enters to advance
The catalytic reaction of one step, to cause that toxic gas reaction is more quick and abundant.Because the implementation of heater 21 has various,
Such as：Resistance heater, microwave applicator etc., and prior art is belonged to, so in the present embodiment for heater 21
Operation principle, temperature control principle and method etc. just not describe in detail.
Embodiment 2：
