Description
Technical field
The utility model particularly relates to a kind of coal burning boiler high-efficiency dust remover.
Background technology
China is a coal-fired big country, Ye Shiyige electricity needs big country.At present, the supply of electric power of China is still based on coal fired power generation, in today of China's rapid economic development, the discharge of a large amount of coal-fired flue-gas, especially the floating dust of particle diameter between 0.5 ~ 5 μm, maximum to human health damage, being the arch-criminal of various poisonous substance in air, is the emphasis of dust prevention and control in air.The dust-collecting efficiency of current existing Coal Electricity deduster is larger by the impact of dust characteristic, and the coal-fired composition of China is ever-changing, dust characteristic is also different, and therefore, coal-fired boiler in power plant uses electric cleaner will reach long-term, efficient, stable dust removal requirement.
Be 201120145303.4 disclose a kind of deduster at Chinese application number, comprise cylindrical shell, described deduster also comprises V-type funnel, sewage draining exit and pneumatic hammer, and cylindrical shell communicates with V-type funnel, and sewage draining exit is connected with V-type funnel, and V-type funnel both sides are provided with pneumatic hammer.Program dedusting is efficient not, and flue dust and dust is not carried out the effect that is separated, and the dust after process is drier, easily again cause dust.
Utility model content
For the problems referred to above, the utility model provides a kind of coal burning boiler high-efficiency dust remover, and this deduster is efficient, stable and the flue dust in boiler can be separated with dust, and the dust after process can not cause dust again.
In order to solve the problem, the technical scheme that the utility model provides is: a kind of coal burning boiler high-efficiency dust remover, comprise cleaner body, preheater, filter bag room, air-introduced machine, chimney, ash discharging hole and reverse blowing device, filter bag room is provided with in described cleaner body, described preheater is connected with cleaner body side by intake stack, described air-introduced machine is connected with cleaner body opposite side by wind pipe, described chimney is connected with air-introduced machine, described ash discharging hole is installed on dust removal machine bottom part body, described reverse blowing device comprises the first hair-dryer, second hair-dryer and purifier, described purifier is connected between the first hair-dryer and the second hair-dryer, described first hair-dryer is all installed on dust removal machine top with the second hair-dryer and is connected with filter bag room.
Preferably, described ash discharging hole is funnel-form.
Further, in described preheater, be provided with airflow uniform distribution device, make flue gas flow rate reduce and evenly enter a bag room.
Preferably, described filter bag room is 2, and described first hair-dryer and the second hair-dryer are connected with two filter bag rooms respectively.
Further, described ash discharging hole is 2, and described each ash discharging hole is placed in below filter bag room respectively.
The beneficial effects of the utility model are: the utility model adopts preheater and airflow uniform distribution device, flue gas is carried out heating and at the uniform velocity processed, the flue gas entering filter bag indoor is made better to form convection circulation, increase flue gas at the indoor filtration time of filter bag, moistening process can be purified to flue gas additionally by reverse blowing device, also can increase the time of flue gas in the indoor filtration of filter bag simultaneously, last dust is got rid of by the ash discharging hole bottom deduster, flue dust is discharged by chimney by the air-introduced machine of upper end, and whole process is more efficient and stable.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1 is cleaner body, 2 is preheater, and 3 is intake stack, and 4 is wind pipe, and 5 is ash discharging hole, and 6 is reverse blowing device, and 7 is purifier, and 8 is filter bag room, and 9 is air-introduced machine, and 10 is chimney.
Detailed description of the invention
Below the utility model is described further:
See Fig. 1: a kind of coal burning boiler high-efficiency dust remover, comprise cleaner body 1, preheater 2, filter bag room 8, air-introduced machine 9, chimney 10, ash discharging hole 5 and reverse blowing device 6, filter bag room 8 is provided with in cleaner body 1, preheater 2 is connected with 3 cleaner body 1 sides by intake stack, air-introduced machine 9 is connected with cleaner body opposite side by wind pipe 4, chimney 10 is connected with air-introduced machine 9, ash discharging hole 5 is installed on bottom dust removal machine main body 1, reverse blowing device 6 comprises the first hair-dryer, second hair-dryer and purifier 7, purifier 7 is connected between the first hair-dryer and the second hair-dryer, first hair-dryer is all installed on dust removal machine top with the second hair-dryer and is connected with filter bag room 8.
Ash discharging hole 5 is funnel-form.
Be provided with airflow uniform distribution device in preheater 2, make flue gas flow rate reduce and evenly enter a bag room.
Filter bag room 8 is 2, and the first hair-dryer and the second hair-dryer are connected with two filter bag rooms 8 respectively.
Ash discharging hole 5 is 2, and each ash discharging hole 5 is placed in below filter bag room respectively.
Operation principle of the present utility model: the flue gas of discharging from boiler air preheater is introduced into diffuser by airduct, is provided with airflow uniform distribution device in diffuser, makes flue gas flow rate reduce and evenly enter a bag room.Flue gas from outside to inside by entering a bag room top box (air-purifying chamber) from sack after sock filtration, then is discharged through exhaust blower.Along with the carrying out of filtering, the pressure reduction inside and outside filter bag increases gradually, and when the differential reaches a set point, soot cleaning system work, until pressure reduction is lower than setting value.Dust under clear is discharged by ash discharging hole, reaches dedusting object.
More than show and describe general principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and description just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
