In order to solve the above-mentioned technical problem, the present invention is achieved by the following technical solutions：A kind of volatilization gas absorbs
Protection device, including ventilation shaft, negative-pressure air fan, filter plant, liquid filter layer and solid filter layer, the ventilation shaft
Two ends are respectively arranged with inlet scoop and air outlet, the negative-pressure air fan, filter plant, liquid filter layer and solid filter layer self-priming
Air port is successively set in ventilation shaft to air outlet direction, and the negative-pressure air fan is produced from the gas that inlet scoop is flowed to air outlet
Stream, the filter plant is handled for gas filtration, the filter core adjustable changeable of the filter plant.
Preferably, the inlet scoop is set to wide-mouth structure.
Preferably, the ventilation shaft is set to flexible duct, and the surface roughness of ventilation shaft inwall is set
For Ra0.8~Ra1.6.
Preferably, the characteristics of ventilation shaft has acid-alkali-corrosive-resisting and high temperature resistant negative pressure.
Preferably, the negative-pressure air fan on be additionally provided with the blinds with automatic open and close function.
Preferably, the ventilation shaft is arranged on the position or workbench both sides relative with staff's standing area.
Preferably, being additionally provided with wind speed test module, wind speed display module, wind speed governor motion on the ventilation shaft
And micro-control unit, the wind speed test module is arranged on inside ventilation shaft, and the wind speed display module is arranged on ventilation
Pipeline external, the wind speed governor motion is arranged on inside ventilation shaft, and the wind speed test module, wind speed show mould
Block, wind speed governor motion are connected with micro-control module by circuit.
Compared with prior art, usefulness of the present invention is：The present invention can effectively contain volatilization harmful gases diffusion,
Allow it to be circulated to absorption plant, block the stimulation to human body, protected during operation without wearing, during operation to environment fitness compared with
Good, discharge gas will not be polluted by processing to environment.
Brief description of the drawings：
The present invention is further described below in conjunction with the accompanying drawings.
Fig. 1 is the structural representation of the present invention.
Embodiment：
Below in conjunction with the accompanying drawings and embodiment the present invention will be described in detail：
A kind of volatilization gas absorption protective device as shown in Figure 1, including ventilation shaft 2, negative-pressure air fan 3, filter plant 4, liquid
Body filter layer 5 and solid filter layer 6, the two ends of the ventilation shaft 2 are respectively arranged with inlet scoop 1 and air outlet 7, the negative pressure
Blower fan 3, filter plant 4, liquid filter layer 5 and the self-priming air port 1 of solid filter layer 6 are successively set on ventilation to the direction of air outlet 7
In pipeline 2, the negative-pressure air fan 3 is produced from the air-flow that inlet scoop 1 is flowed to air outlet 7, and the filter plant 4 is used for gas mistake
Filter is handled, the filter core adjustable changeable of the filter plant 4；The present invention is applied to protection people according to airflow principle
With in environment, adhere to it is people-oriented, using environmental protection as principle, poisonous and hazardous volatilization gas is absorbed with airflow,
Effective processing is done before discharge, with being handled before human contact, is not becoming nontoxic gas discharge, so as to form peace
The working environment that loopful is protected.
In actual use in order to increase the air intake region of inlet scoop 1, the inlet scoop 1 is set to wide-mouth structure, and then
Effectively volatilization gas can be prevented to be diffused into air.
As the preferred arrangement of ventilation shaft 2, in order to meet the use demand of varying environment, the ventilation shaft 2
Be set to flexible duct, if the surface roughness of the inwall of ventilation shaft 2 is higher in addition, then cause in gas impurity easy-adhesion
On the inwall of ventilation shaft 2, it is difficult to clear up in the course of time and causes ventilation shaft 2 to turn into pollution sources, therefore the ventilation shaft 2
The surface roughness of wall is set to Ra0.8~Ra1.6.
The characteristics of there is corrosivity and high temperature due to most of volatilization gas, therefore the ventilation shaft 2 has acid and alkali-resistance
The characteristics of corrosion and high temperature resistant negative pressure, to ensure the service life of ventilation shaft 2.
During volatilization gas absorption protective device is opened and is closed, in order to realize the logical of ventilation shaft internal gas flow
It is disconnected, the blinds with automatic open and close function is additionally provided with the negative-pressure air fan 3.
As the preferred arrangement of the set location of ventilation shaft 2, the ventilation shaft 2 is arranged on stands with staff
