Description
Technical field
Industry environmental protection field is the utility model is related to, more particularly to a kind of device for being used to handle indoor exhaust air.
Background technology
In current in the market, indoor exhaust-gas treatment may be discharged directly, it is also possible to be located by exhaust system
Reason.Conventional exhaust system has gravity-flow ventilation and force ventilation two ways, gravity-flow ventilation：It is in the bottom of exterior wall bottom OR gate dress
Air grille, vertical shaft is set on the inside of room, it is only applicable to the low room of concentration of narmful substance, suitable for indoor temperature it is high with
The occasion of outside air temperature.Force ventilation：It is that blower fan is installed on exterior wall, is made up of blower fan, air channel, exhaust hood.
If waste gas directly discharged, huge destruction will be caused to environment, do not meet China and develop at this stage always
Ask, also violate the requirement of relevant environment preservation law regulation.If waste gas is simply used into water treating pond or chemical agent
Processing pond is handled, and its absorption efficiency is limited.
The Xi Jinping General Secretary points out that blue montains and green waters is exactly Kingsoft Yin Shan.Indoor exhaust air processing unit is developed, is lifted at waste gas
Effect is managed, reduces exhaust-gas treatment cost, is exactly to practice the scientific judgment for practising the General Secretary on economic development, will bring huge
Social and economic benefit.
Utility model content

Manage surfacecti proteon laboratory waste air equipment.In order to realize purpose of utility model of the present utility model, the utility model devises
A kind of surfacecti proteon laboratory waste air equipment, using liquid phase and solid phase integrated treatment, conventional exhaust system have gravity-flow ventilation and
Force ventilation two ways.
In one side of the present utility model, there is provided a kind of device for being used to handle indoor exhaust air, it is characterised in that institute
The device stated include be sequentially arranged exhaust hood (1), acid absorb groove (4), Alkali absorption groove (5) and activated carbon absorption groove (7) and
Blower fan (9)；Described exhaust hood (1) is connected to indoor exhaust air source；And described blower fan (9) is operated and is evacuated from device.
At preferable aspect, absorbing the exhaust duct (2) between groove (4) in exhaust hood (1) and acid also includes volume damper
(3)。
At preferable aspect, be provided with acid absorbs groove (4) and Alkali absorption groove (5) first annular blast pipe (6-2) and
Second annular vent pipe (6-1).
At preferable aspect, described activated carbon, which absorbs groove (7), to be included being arranged on the activated carbon adsorption layer in the middle part of cell body
(8)。
At preferable aspect, in described acid absorbs groove (4), absorbing liquid is dilute H2SO4。
In a further preferred aspect, described absorbing liquid includes 0.03-1.5mol/L H2SO4。
At preferable aspect, in described Alkali absorption groove (5), absorbing liquid is dilute NaHCO3Solution.
In a further preferred aspect, described absorbing liquid includes 0.03-1.5mol/L NaHCO3。
At the preferable aspect of the utility model, exhaust hood is connected with exhaust duct, and volume damper is arranged on exhaust duct, acid
Absorb groove, Alkali absorption groove, activated carbon to link together by exhaust duct between absorbing groove, annular vent pipe is arranged in acid and absorbs groove
With Alkali absorption trench bottom, uniformly it is covered with aperture above annular vent pipe.Activated carbon adsorption layer in groove is absorbed in activated carbon to be arranged on
On activated carbon adsorption layer support, blower fan is connected to activated carbon by exhaust duct and absorbed on groove.
Waste gas is forced to suck by blower fan, and the gas of alkali can be dissolved in by part by entering acid absorption groove by exhaust hood and exhaust duct
Or all absorb, acid absorbs groove built with NaHCO3Solution, residual gas enter Alkali absorption groove, and Alkali absorption groove is built with dilute
H2SO4, it is dissolved in dilute H2SO4Alkaline gas largely or entirely absorbed, be left gas enter activated carbon absorb groove by activated carbon
Adsorption layer partly or entirely absorbs, and very little will not reproduce into atmosphere pollution to residual gas concentration.
Annular vent pipe is arranged in acid and absorbs groove and Alkali absorption trench bottom, is uniformly covered with aperture, gas above annular vent pipe
Body is discharged and fully contacted with liquid upwards from trench bottom, absorption it is abundant, residual is few.Waste gas is discharged into work upwards from trench bottom
Property charcoal absorb groove, fully contact with activated carbon adsorption layer, partly or entirely absorbed absolutely, excluded through exhaust outlet.
The advantages of the technical solution of the utility model, is, is arranged by the order of waste gas absorption handling implement so that inhale
Rate of producing effects improves, and also extends the life-span of exhaust treatment system pipeline.Device of the present utility model is compared with other ventilating systems
Waste gas is few by purifying contaminated residual, absorbs fully, secondary pollution will not be caused to air, absorptivity is up to more than 90%.
