Description

Energy-efficient chimney

Technical field

The utility model relates to a kind of chimney, specifically is a kind of energy-efficient chimney.

Background technology

Present most of combustion apparatus all is to be fuel with the coal, and existing chimney is just smoked and smoke evacuation, simply flue gas is sent to high altitude discharge, diffusion, and this discharging modes are brought very big pollution to environment.Be the harmful substance in removing smoke, generally take to be provided with cleaner, so both increased cost of investment, increased floor space again.Announced the multiple chimney that is used to purify flue gas at Chinese patent, " gas cleaning chimney stack " as the patent No. 200620050411.2, the bottom of this chimney is the lime pond, middle lower floor is the spray district that several floor shower nozzle are installed, the upper strata is equipped with shutter, this chimney has certain limitation to the height of chimney, must use high-pressure pump that limewash is atomized, structure is comparatively complicated, limewash strengthens the corrosion of equipment simultaneously, some energy-saving chimneys have also been announced, generally be two-layer inside and outside chimney is set to, between ectonexine, be provided with the metal coil pipe, flue gas is walked on the lateral of inner chimney in use, walk downward up to the top, then the passage from the Lower Half of inner chimney leaves whole chimney through the inner chimney open top, be connected with flowing cold water in the metal coil pipe, the entrained heat of flue gas can be absorbed by the metal dish tube portion, cold water is added heat utilization, though this chimney has been realized the entrained waste heat of flue gas utilized process again, reached energy-conservation effect, but not good to the harmful substance treatment effect in the flue gas.

Summary of the invention

The purpose of this utility model is a kind of combustion furnace, boiler, smelting furnace, furnace cupola, kiln and chemical industry stove of being applicable to, effectively the multifunctional chimney that flue gas is carried out smoke abatement and dust control, desulfurization, the energy-efficient chimney that the waste heat in the flue gas is utilized again.

In order to achieve the above object, the technical solution of the utility model is:

Energy-efficient chimney of the present utility model, at the bottom of including the tower of the body of the tower in cat head, middle level on upper strata and lower floor, gas approach and exhanst gas outlet, in the cat head on upper strata, from top to bottom arrange the porous adsorption plate, in the body of the tower in middle level, be furnished with the spray thrower that many group spray equipments and porous plate are formed, gas baffle, residual-heat exchanger and clear water layer from top to bottom are set at the bottom of the tower of lower floor, be connected with residual-heat exchanger at gas approach, bottom at residual-heat exchanger is provided with dust flue, in the bottom of clear water layer blow-off pipe is set.

Adopt technique scheme that following beneficial effect is arranged:

The smoke inlet of flue gas at the bottom of the tower enters the chimney, directly contact with residual-heat exchanger and to carry out heat exchange, heat in the flue gas is delivered in the flowing water rapidly by heat pipe, realization reaches energy-conservation effect to afterheat utilization in the flue gas, when rising to gas baffle, flue gas around baffle plate, distributes, gas baffle can block in the water inflow residual-heat exchanger that is sprayed by body of the tower herein, avoids heat pipe to be corroded.At the water bag of the center of residual-heat exchanger for surrounding by housing, assigned heat pipe heat in the housing side, outlet pipe is arranged at the top, and water inlet pipe and scale removing tube are arranged at the bottom; There is gas baffle the residual-heat exchanger top, the shell wall of side and water bag forms exhaust gases passes, and dust flue is arranged at the bottom, in residual-heat exchanger is placed at the bottom of the tower by gripper shoe, bottom at the bottom of tower is to have from cat head and body of the tower to spray the water layer that flows down formation, can discharge by blow-off pipe.

When flue gas enters first spray thrower of body of the tower, to pass through the moisture film that aperture forms on the porous plate earlier, entered after first the cleaning that the spray space is sprayed, washing, film wash, atomize, after washing, leave and enter into second spray thrower through the porous plate film on upper strata; Flue gas is after passing through a plurality of spray throwers, and the dustiness in the flue gas, sulfide, nitrogen oxide, carbide content constantly reduce, if spray when selecting alkaline solution for use, desulfurization, denitration effect are better.

When flue gas enters cat head, sprayed for the last time and entered porous adsorption layer after film is washed, in porous adsorption layer, formed the porous adsorption plate, can absorb moisture, flue gas and harmful substance wherein, by exhanst gas outlet the tail gas after purifying has been arranged in atmosphere at last by the strong cotton body of many adsorptivities.
