The waste heat utilization device comprises a flue gas passage and a water tank; the flue gas passage runs through the integral water tank; the top of the water tank is provided with a water inlet; the water inlet is provided with a first valve; the bottom of the water tank is provided with a water outlet; the water outlet is provided with a second valve; an outlet of the flue gas passage is connected with an inlet of the dust collection device; a first filter membrane and a second filter membrane are longitudinally arranged inside the dust collection device; an outlet of the dust collection device is connected with an inlet of the waste gas adsorption device; an adsorption layer is longitudinally arranged in the waste gas adsorption device; and the side wall of the waste gas adsorption device is provided with an exhaust port. The flue gas processing device for the coal fired boiler has the beneficial effects that waste heat of flue gas discharged by the coal fired boiler is recycled and particulate matter, sulfur oxide and carbonic oxide in the flue gas are removed; pollution of the flue gas to the environment is obviously reduced; and the flue gas processing device for the coal fired boiler is energy-saving and environmental-friendly.
Description
Technical field
The utility model belongs to exhaust-gas treatment field, especially relates to a kind of fire coal boiler fume treating apparatus.
Background technology
For there is no central heating and not possessing the combination area of city and country of gas-heating condition and vast rural area, most of family still adopts the coal-burning boiler use of warming oneself and cook.In the flue gas that coal-burning boiler is discharged, contain a large amount of dust and oxycarbide, oxysulfide etc., be directly discharged in air, to environment, caused great pollution, and also brought many hidden danger to people's health.
Utility model content
The purpose of this utility model is to provide a kind of fire coal boiler fume treating apparatus, and the flue gas of coal-burning boiler is carried out waste heat recovery recycling and and flue gas carried out discharging after purified treatment again.
The technical solution of the utility model is: a kind of fire coal boiler fume treating apparatus, comprise residual heat using device, dust arrester and exhaust gas adsorption device, described residual heat using device comprises exhaust gases passes and water tank, described exhaust gases passes runs through whole water tank, the top of described water tank is provided with water inlet, on described water inlet, be provided with the first valve, the bottom of described water tank is provided with delivery port, on described delivery port, be provided with the second valve, the outlet of described exhaust gases passes is connected with the entrance of dust arrester, the inside of described dust arrester is vertically arranged with the first filter membrane and the second filter membrane, the outlet of described dust arrester is connected with the entrance of exhaust gas adsorption device, in described exhaust gas adsorption device, be vertically arranged with adsorption layer, the sidewall of described exhaust gas adsorption device is provided with exhaust outlet.
Further, described water tank be shaped as hollow cylinder, the internal diameter of described hollow cylinder is identical with the diameter of exhaust gases passes.
Further, the aperture of described the first filter membrane is greater than the aperture of the second filter membrane.
Further, described adsorption layer consists of active carbon.
Advantage and the good effect that the utlity model has are: owing to adopting technique scheme, the waste heat of the flue gas of being discharged by coal-burning boiler can fully be recycled, particle in flue gas is removed by the first filter membrane and the second membrane filtration, in addition, oxysulfide in flue gas and oxycarbide are adsorbed to be removed, significantly reduced the pollution to environment of flue gas that coal-burning boiler discharges, energy-conserving and environment-protective.
Accompanying drawing explanation

The specific embodiment
Below in conjunction with accompanying drawing, the utility model is elaborated.
As shown in Figure 1, a kind of fire coal boiler fume treating apparatus of the utility model, comprise residual heat using device 1, dust arrester 2 and exhaust gas adsorption device 3, described residual heat using device 1 comprises exhaust gases passes 4 and water tank 5, described exhaust gases passes 4 runs through whole water tank 5, the top of described water tank 5 is provided with water inlet 6, on described water inlet 6, be provided with the first valve 7, the bottom of described water tank 5 is provided with delivery port 8, on described delivery port 8, be provided with the second valve 9, the outlet of described exhaust gases passes 4 is connected with the entrance of dust arrester 2, the inside of described dust arrester 2 is vertically arranged with the first filter membrane 10 and the second filter membrane 11, the outlet of described dust arrester 2 is connected with the entrance of exhaust gas adsorption device 3, in described exhaust gas adsorption device 3, be vertically arranged with adsorption layer 12, the sidewall of described exhaust gas adsorption device 3 is provided with exhaust outlet 13, described water tank 5 be shaped as hollow cylinder, the internal diameter of described hollow cylinder is identical with the diameter of exhaust gases passes 4, the aperture of described the first filter membrane 10 is greater than the aperture of the second filter membrane 11, described adsorption layer 12 consists of active carbon.
The course of work of this example: the exhaust gases passes of this fire coal boiler fume treating apparatus 4 is connected with the blast pipe of coal-burning boiler, the flue gas that coal-burning boiler produces enters residual heat using device 1 through exhaust gases passes 4, flue gas enters dust arrester 2 after by the water cooling in water tank 5, in dust arrester 2, bulky grain in flue gas and granule are removed by filter by the first filter membrane 10 and the second filter membrane 11 successively, flue gas after dedusting enters exhaust gas adsorption device 3, oxysulfide in flue gas and oxycarbide molecule major part are by active carbon adsorption, flue gas after purification is discharged by exhaust outlet 13, greatly reduced the pollution to environment, water in water tank 5 can be emitted from delivery port 8 after by the waste-heat of flue gas, for people's domestic water, when in water tank 5, the water yield is less, can add from water inlet 6, fully recycle the waste heat of flue gas, save the energy.
Above an embodiment of the present utility model is had been described in detail, but described content is only preferred embodiment of the present utility model, can not be considered to for limiting practical range of the present utility model.All equalization variations of doing according to the utility model application range and improvement etc., within all should still belonging to patent covering scope of the present utility model.
