Abstract
The utility model discloses a low-resistance whirlwind type boiler duster with heat-exchange function, comprising a dust-contained airflow inlet [1], a whirlwind cylindrical shell [7], a whirlwind ash hopper [10], a net gas outlet [4], a dust exhausting valve [9], etc. The utility model is characterized in that the whirlwind cylindrical shell [7] is a log spiral whirlwind cylindrical shell, a heat exchange spiral water pipe [6] is arranged in the whirlwind cylindrical shell [7], and simultaneously, a bottom plate [11] of the boiler duster is arranged between the whirlwind cylindrical shell [7] and the whirlwind ash hopper [10]. The utility model has the advantages of simple structure, low cost, convenient maintenance, good dust removing effect, dust removing and heat exchange, and can be used to replace the precious boiler economizer.
Description
The utility model relates to a kind of heat exchange low resistance cyclone deduster.
At present, the cyclone dust collectors that use all only as gathering dust and usefulness, generally all comprise dust-contained airflow inlet (1) both at home and abroad, cyclone cylinder (7), whirlwind ash bucket (10), pure qi (oxygen) outlet (4), flange (5), dust discharge valve (9) etc.The dust constaining air-flow enters cyclone cylinder (7) by dust-contained airflow inlet (1), in cylindrical shell (7), the air-flow rotation, produce centrifugal force, soot dust granule is separated, the grit of collecting gathers in the whirlwind ash bucket (10), regularly removes through the dust discharge valve, and the air-flow after the purification is through pure qi (oxygen) outlet (4) discharging.Such deduster all adopts steel to make, and is high temperature resistant, can be used for the clarifying smoke of industrial furnace, still, but still has been discharged into atmosphere for heat contained in the high-temperature flue gas, caused the thermal pollution of atmosphere and the waste of heat energy.And the gas-flow resistance loss is bigger, serious wear, the coating that has wearing layer, also can only use about 1 year.
The purpose of this utility model be to provide a kind of can dedusting, can reclaim the heat exchange low-resistance deduster of contained heat energy in the flue gas again, to reduce to the thermal pollution of atmosphere and the waste of heat energy.
Solution of the present utility model is the log spiral principle that forms according to sand-flood, make the log spiral Whirlwind barrel, the heat exchange pipe with spiral pipe is installed in the log spiral Whirlwind barrel, make cold water and high-temperature flue gas in the water pipe carry out heat exchange, reclaim a large amount of heat energy in the high-temperature flue gas, reduce the thermal pollution of atmosphere and the waste of heat energy.Simultaneously, between log spiral Whirlwind barrel and whirlwind ash bucket, be provided with the deduster base plate,, reduce the whirlpool loss of energy to cut off forced vortex rotation air-flow.
The utility model comprises the dust-contained airflow inlet, Whirlwind barrel, the whirlwind ash bucket, the pure qi (oxygen) outlet, flange, dust discharge valve, it is characterized in that Whirlwind barrel is the log spiral Whirlwind barrel, the heat exchange pipe with spiral pipe is installed in Whirlwind barrel, simultaneously, between log spiral Whirlwind barrel and whirlwind ash bucket, is provided with the deduster base plate.Its feature also is to be equipped with in the log spiral Whirlwind barrel two groups, three groups or organize the heat exchange pipe with spiral pipe more, to improve heat exchange efficiency.Flow through dust-contained airflow inlet of the ash-laden gas of high temperature, enter in the log spiral Whirlwind barrel, in Whirlwind barrel, the air-flow rotation, produce centrifugal force, soot dust granule is separated, the grit of collection gathers in the whirlwind ash bucket, open the dust discharge valve and regularly remove, the air-flow after the purification is through pure qi (oxygen) outlet discharging.In the dust constaining air-flow rotation separating process of high temperature, because the rotation of air-flow, produce eddy current, make air-flow along the pipe with spiral pipe horizontal stroke, vertically wash away, produce strong heat exchange effect, heat is passed to the cold water that is flowed into pipe with spiral pipe by cooling water inlet, and the water behind the absorption heat is sent into boiler or is made other purposes by hot water outlet.Between log spiral Whirlwind barrel and whirlwind ash bucket, be provided with the deduster base plate, can cut off forced vortex rotation air-flow, reduce the whirlpool loss of energy.
Fig. 1 is a structure principle chart of the present utility model.
Fig. 2 is a vertical view of the present utility model.
The utility model is described in further detail below in conjunction with accompanying drawing.
The utility model as shown in Figure 1, it comprises dust-contained airflow entrance (1), Whirlwind barrel (7), whirlwind ash bucket (10), pure qi (oxygen) outlet (4), flange (5), dust discharge valve (9), the Whirlwind barrel (7) that is characterised in that of the present utility model is the log spiral Whirlwind barrel, is provided with deduster base plate (11) between log spiral Whirlwind barrel (7) and whirlwind ash bucket (10). Be further characterized in that in the log spiral Whirlwind barrel (7). Be equipped with two groups, three groups or organize heat exchange pipe with spiral pipe (6), to improve heat exchange efficiency, as shown in Figure 1, be the situation that the heat exchange pipe with spiral pipe (6) of three groups of various outer diameters is installed more. The ash-laden gas of the high temperature dust-contained airflow entrance (1) of flowing through, enter in the log spiral Whirlwind barrel (7), in Whirlwind barrel (7), flow rotation produces centrifugal force, and soot dust granule is separated, the grit of collecting gathers in the whirlwind ash bucket (10), open dust discharge valve (9), regularly remove, the air-flow after the purification is through pure qi (oxygen) outlet (4) discharging. In the process of the dust constaining air-flow rotating separation of high temperature, because the rotation of air-flow, produce eddy current, make air-flow horizontal along heat exchange pipe with spiral pipe (6), vertically wash away, produce strong heat exchange effect, heat is passed to the cold water that is flowed into heat exchange pipe with spiral pipe (6) by cooling water inlet (8), and the water behind the absorbing heat is sent into boiler or is made other purposes by hot water outlet. Between log spiral Whirlwind barrel (7) and whirlwind ash bucket (10), be provided with deduster base plate (11), can play partition, forced vortex rotation air-flow, reduce the whirlpool loss of energy.
The utility model is simple in structure, and cost is low, and dust-collecting efficiency reaches more than 80%, and resistance loss is below 300 handkerchiefs, and the coefficient of heat transfer is more than 40. This deduster can play the effect of gathering dust of cyclone dust collectors, can play again the effect of boiler economizer; Particularly can directly replace present boiling boiler, the economizer of coal-powder boiler, and the heat exchanging water pipe need not artificial deashing. If be installed on the lower grate furnace of dust exhausting concentration, can reach the secondary row mark requirement of China.
Embodiment:
Log spiral Whirlwind barrel of the present utility model (7) can be rolled with veneer reeling machine by cold bundle or heat bundle thin plate and form, top board (3), whirlwind ash bucket (10), deduster base plate (11) all are connected with flange with log spiral Whirlwind barrel (7), its airflow inlet (1), outlet (4) all are connected with flange with flue, dust-exhausting port is provided with dust discharge valve (9), so that lock gas and ash discharge.Heat exchange pipe with spiral pipe (6) bends with the pachydermia seamless pipe and forms, and is screwed with deduster, so that the dismounting when changing.
