Description
Technical field
The present invention relates to environmental protecting device field, specially a kind of waste gas afterheat recovery unit.
Background technique
As the collection of urban population neutralizes the development of modern industry, the pollutant for being discharged into atmosphere is more and more, so that air
Quality decline, exhaust gas heat content itself is larger, so that a large amount of waste heat is unutilized, directly exhausts gases into atmosphere, no
It only pollutes the environment, but also wastes thermal resource, be unfavorable for energy-saving and emission-reduction.The continuous depth of Environmental pollution and prevention and treatment
Enter, the emission request of enterprise's exhaust gas is become strictly, existing emission-control equipment mostly has ignored mainly for purifying exhaust gas
Heat is lost in exhaust gas,
General heat pipe-type waste gas afterheat recovery unit can recycle waste-gas heat, and the heat of recycling may be used as producing as needed
With moisturizing and domestic water, but structure is more complex, and low to exhaust purification efficiency, it would therefore be desirable to more than existing exhaust gas
Heat recovery apparatus improves, to solve problem above.
Summary of the invention
To achieve the above object, the invention provides the following technical scheme: a kind of waste gas afterheat recovery unit, including shell,
Air inlet is set on the left of the shell, gas outlet is set on the right side of the shell, heat-exchange tube, the heat is arranged in the enclosure interior
It exchanges pipe lower part and inlet is set, top is arranged liquid outlet, the first filter screen, first mistake is arranged on the left of the heat-exchange tube
It aperture of filter screen fine uniform and is fitted closely with inner walls, the second filter screen of setting and active carbon fibre on the right side of the heat-exchange tube
Tie up layer.
As a preferred technical solution of the present invention, first filter screen and the second filter material are cotton fibre
Tie up material.
It is granular activated carbon inside the activated carbon fiber layers as a preferred technical solution of the present invention.
As a preferred technical solution of the present invention, the heat-exchange tube of crossing is made of resistant material.
Compared with prior art, the beneficial effects of the present invention are: the waste gas afterheat recovery unit, close in device housing
The first filter screen is arranged in air inlet, and exhaust gas is entered after device by air inlet to be filtered through the first filter screen, filtered gas
Body absorbs the heat in exhaust gas by heat-exchange tube, heat-exchange tube, and the gas after heat-exchange tube is through the second filter screen and work
Property Carbon fibe layer filtering and absorption, remove gas in other substances after by gas outlet discharge, prevent the dust in exhaust gas
It is again introduced into atmosphere with solid particulate matter, causes secondary pollution, the device structure is simple, and production cost is low, may be implemented simultaneously
The waste heat and purification exhaust gas in exhaust gas are recycled, exhaust gas discharge is reduced, energy conservation and environmental protection is killed two birds with one stone, and has higher utility value.
Detailed description of the invention
Fig. 1 is schematic structural view of the invention；
In figure: 1- shell；2- air inlet；The gas outlet 3-；4- heat-exchange tube；5- inlet；6- liquid outlet；The first filter screen of 7-；
The second filter screen of 8-；9- activated carbon fiber layers.
Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
Embodiment:
Referring to Fig. 1, the present invention provides a kind of technical solution: a kind of waste gas afterheat recovery unit, including shell 1, the shell 1
Air inlet 2 is arranged in left side, and gas outlet 3 is arranged on the right side of the shell 1, and heat-exchange tube 4 is arranged inside the shell 1, and the heat is handed over
4 lower part of pipe setting inlet 5 is changed, liquid outlet 6 is arranged in top, is arranged the first filter screen 7 on the left of the heat-exchange tube 4, and described the
It one filter screen, 7 aperture fine uniform and is fitted closely with 1 inner wall of shell, 8 He of the second filter screen is set on the right side of the heat-exchange tube 4
Activated carbon fiber layers 9.
Preferably, first filter screen 7 and 8 material of the second filter screen are cotton fibre material；The active carbon
It is granular activated carbon inside fibrous layer 9；The heat-exchange tube 4 of crossing is made of resistant material.
Specifically used mode and advantage: the waste gas afterheat recovery unit, close to air inlet setting first in device housing
Filter screen, exhaust gas is entered after device by air inlet to be filtered through the first filter screen, and filtered gas passes through heat-exchange tube,
Heat-exchange tube absorbs the heat in exhaust gas, filtering of the gas through the second filter screen and activated carbon fiber layers after heat-exchange tube
And absorption, it removes after other substances in gas through gas outlet discharge, prevents dust in exhaust gas and solid particulate matter again
Into atmosphere, secondary pollution is caused, the device structure is simple, and production cost is low, may be implemented to recycle the waste heat in exhaust gas simultaneously
With purification exhaust gas, exhaust gas discharge is reduced, energy conservation and environmental protection is killed two birds with one stone, and has higher utility value.
It is obvious to a person skilled in the art that invention is not limited to the details of the above exemplary embodiments, Er Qie
In the case where without departing substantially from spirit or essential attributes of the invention, the present invention can be realized in other specific forms.Therefore, no matter
