Abstract
The invention provides a flue heat exchange device for hot-air blowing and sweeping and sealing of insulation piece incubators of an electric precipitator. The flue heat exchange device comprises the electric precipitator. The front end of the electric precipitator is communicated with a flue pipe through a heat exchanger. A hot-air inlet of the heat exchanger is communicated with a cold-air pipe through a fan. A hot-air outlet of the heat exchanger is communicated with the insulation incubators of the electric precipitator through a hot-air pipe. Air heated by the heat exchanger is sent to the insulation piece incubators. According to the flue heat exchange device, waste heat of smoke is utilized to heat the air to be used for heating, blowing and sweeping and sealing the insulation piece incubators of the electric precipitator, electricity consumption and steam consumption are saved, and the operation cost of the electric precipitator is lowered.
Description
Technical field
The invention belongs to environmental project electric cleaner technical field, be specifically related to a kind of electric cleaner insulating part incubator hot blast sealing flue heat-exchanger rig.
Background technology
Electric cleaner system utilizes electrion, electrostatic dust collection to reach the environmental protection equipment of dedusting object.Under discharge electrode is operated in high-voltage state, the support of discharge electrode and the rotation of rapping apparatus thereof must rely on the insulating part such as electroceramics or quartz.Because dust in flue gas is easily bonded in insulating part surface, simultaneously flue gas also can at insulating part surface sweating, thus cause insulating part creepage due to low temperature, and cause the damage of insulating part, under causing electric cleaner often to run on low-voltage state, efficiency of dust collection is low.
Hot-blast Heating, purging, Sealing Technology add hot-air exactly and form hot blast, hot blast is utilized to heat insulating part incubator, purge, ensure the clean drying of insulating part, prevent condensation, in insulating part incubator, form pressure-fired simultaneously, prevent the flue gas in electric cleaner from entering incubator and pollute insulating part.Hot-blast Heating, purging, Sealing Technology are now more to be applied on electric cleaner.It generally adopts electric heat exchange or steam heat-exchanging for the heat exchanger adding hot-air, adds somewhat to the operating cost of traditional electrical dedusting.
General employing hot-air blowing Sealing Technology solves the electric cleaner running temperature all higher (flue-gas temperature is more than 200 or 300 DEG C) of Insulation Problems, utilizes fume afterheat to add hot-air to heat, purges, sealing insulator incubator is a kind of method reducing electric cleaner operating cost.
Summary of the invention
In order to overcome the shortcoming of above-mentioned prior art, the object of this invention is to provide a kind of electric cleaner insulating part incubator hot blast sealing flue heat-exchanger rig, flue gas in flue waste heat is utilized to form hot blast to add hot-air, hot blast after heating is used for heating, purging, sealed electrical deduster insulating part incubator, no longer adopt electricity or steam heat-exchanging to add hot-air, thus reduce the operating cost of electric precipitation.
For achieving the above object, the present invention adopts following technical scheme:
A kind of electric cleaner insulating part purges sealing hot air flue heat-exchanger rig, comprise electric cleaner 2, the front end of electric cleaner 2 is communicated with flue by heat exchanger 4, the hot-wind inlet of heat exchanger 4 is communicated with cold-air duct by blower fan 3, and the hot-blast outlet of heat exchanger 4 is communicated with the thermal insulating case 1 of electric cleaner 2 by hot air duct 5.
It is orthogonal or circular that described heat exchanger 4 obtains profile design according to flue, the two ends, left and right of heat exchanger 4 are respectively equipped with a mounting flange 6, the shell of heat exchanger 4 becomes three-decker, internal layer 7 crowds around the exhaust gases passes be welded into for steel plate, intermediate layer 8 and outermost layer 9 is provided with successively outside internal layer 7, outermost layer 9 is heat-insulation layer, the clearance space reserved between internal layer 7 and intermediate layer 8, adopt band steel 10 to erect spiral wound to be welded and fixed, helical airflow passage 11 is formed between internal layer 7 and intermediate layer 8, the hot-wind inlet of helical airflow passage 11 exports with blower fan 3 and is connected, the hot-blast outlet of helical airflow passage 11 is connected with hot air duct 5.
