Abstract
The utility model discloses a direct-fired type waste gas purification device, which comprises an air inlet heat exchanger, a combustion reaction chamber, a mixing channel, a draught fan and a combustion engine. The air inlet heat exchanger comprises an air inlet channel and an air outlet channel, the air inlet channel is connected with the combustion reaction chamber and then connected with the mixing channel, and the mixing channel is connected with the air outlet channel and then connected with the draught fan through an air pipe. The combustion engine is arranged at the position of the combustion reaction chamber, and a cone-shaped multi-hole diffuser is arranged between the combustion reaction chamber and the air inlet channel. By means of the technical scheme, the direct-fired type waste gas purification device fully and evenly mixes waste gas and can treat the waste gas which is large in air quantity and contains heavy metal ions with high and middle concentration. The air outlet channel transfers heat of treated gas to the waste gas in the air inlet channel, thereby saving energy.
Description
Technical field
The utility model relates to a kind of waste gas purification apparatus, relates in particular to a kind of direct-fired waste gas purification apparatus.
Background technology
The direct-fired waste gas purification apparatus of prior art, waste gas directly gets into the hybrid channel, and is inhomogeneous during the waste gas access arrangement, and flame and waste gas are short time of contact when carrying out burn processing, cause waste gas burning insufficient, and the generation of (VOC) NMHC is arranged.Better for general air quantity, exhaust-gas treatment effect that concentration is lower, but to big air quantity, the waste gas burning that contains heavy metal ion high, middle concentration is incomplete, and purifying rate is not up to standard.
Summary of the invention
Goal of the invention: the purpose of the utility model is the deficiency to prior art, provides a kind of and can handle big air quantity, the direct-fired waste gas purification apparatus of the waste gas that contains heavy metal ion of high, middle concentration.
Technical scheme: in order to realize the foregoing invention purpose, the technical scheme that the utility model adopted is:
A kind of direct-fired waste gas purification apparatus; Comprise air intake heat exchanger, combustion reaction chamber, hybrid channel, air-introduced machine and combustor; Described air intake heat exchanger comprises inlet channel and outlet passageway, and described inlet channel is connected the back and is connected with the hybrid channel with the combustion reaction chamber, and the hybrid channel is connected the back and is connected to air-introduced machine through ventilation duct with described outlet passageway; The place is provided with combustor in the combustion reaction chamber, between described combustion reaction chamber and inlet channel, is provided with the taper porous air diffuser.
Described hybrid channel is provided with heat-preservation cotton.
Be provided with heat-exchanger rig at the air-introduced machine leading portion.
Beneficial effect: the utility model compared with prior art, its beneficial effect is:
1, between combustion reaction chamber and inlet channel, is provided with the taper porous air diffuser, before the inlet channel entering hybrid channel of waste gas, waste gas carried out evenly mixing fully through the taper porous air diffuser through the air intake heat exchanger;
2, the air intake heat exchanger is provided with inlet channel and outlet passageway, and the gas after the burn processing and the waste gas of entering carry out heat exchange, the waste gas cooling after the processing, and the waste gas of entering heats up, and has improved treatment effect, has saved the energy simultaneously;
3, the hybrid channel is provided with heat-preservation cotton, and the temperature in the hybrid channel is continued at high temperature, has saved the energy when combustor waste gas burns;
4, be provided with heat-exchanger rig at the air-introduced machine leading portion, further reduced the temperature of handling back gas, make it reach the safe temperature device for transferring, improved security performance.
Description of drawings
Accompanying drawing is the utility model structural representation.
The specific embodiment
Below in conjunction with accompanying drawing, through a most preferred embodiment, the utility model technical scheme is elaborated, but the protection domain of the utility model is not limited to said embodiment.
As shown in the figure; A kind of direct-fired waste gas purification apparatus comprises air intake heat exchanger 1, combustion reaction chamber 4, hybrid channel 5, air-introduced machine 8 and combustor 3, and described air intake heat exchanger 1 comprises inlet channel and outlet passageway; Described inlet channel is connected the back and is connected with hybrid channel 5 with combustion reaction chamber 4; Hybrid channel 5 is connected the back and is connected to air-introduced machine 8 through ventilation duct 6 with described outlet passageway, 4 places are provided with combustor 3 in the combustion reaction chamber, between described combustion reaction chamber 5 and inlet channel, are provided with taper porous air diffuser 2; Described hybrid channel is provided with heat-preservation cotton 9, is provided with heat-exchanger rig 7 at air-introduced machine 8 leading portions.
Operation principle: waste gas gets into through the inlet channel of air intake heat exchanger 1; 2 pairs of waste gas of taper porous air diffuser carry out evenly mixing fully; Mixed waste gas in 3 pairs of combustion reaction chambers of combustor 4 carries out burn processing; Waste gas after the processing is handled in hybrid channel 5 once more, and the gas after the processing gets into the outlet passageway of air intake heat exchanger 1, reduces the temperature of self when the waste gas that continues to get into is heated; Gas after the cooling gets into through ventilation duct 6 and continues cooling in the heat-exchanger rig 7, and the gas after will handling through air-introduced machine 8 is then discharged.
