Abstract
The invention discloses a dust removal method for a boiler body of a thermal power plant. The boiler body is mainly composed of a negative-pressure centrifugal fan, an efficient cyclone separator and a bag type dust collector. The method is characterized by comprising the steps that dust on a boiler device and negative pressure air in a pipeline are evenly mixed to form gas-solid two-phase flow, the gas-solid two-phase flow enters the cyclone separator, primary coarse powder and impurity separation is conducted under the effect of vortex centrifugal force, coarse ash and impurities are discharged through a gate valve on the lower portion of the separator, and the gate valve is controlled through a material level switch; gas exhausted through the efficient cyclone separator enters the bag type dust collector for secondary separation; and tail gas is exhausted to a flue (an inlet of an electrostatic dust collector) through the negative-pressure centrifugal fan. According to the method, continuous high-negative-pressure ash removal can be achieved based on a centrifugal negative pressure principle; the device maintenance quantity is small, the air volume of the fan is large, multiple suction openings can be opened at the same time for work, and the method is an ideal dust removal processing scheme for the boiler body of the thermal power plant and has popularization value.
Description
Technical field
The present invention relates to dedusting technology field, be specifically related to a kind of power plant boiler body dust collection method.
Background technology
In China, modern heat power plant boiler is commonly used cleaner and is usually adopted following three kinds of forms: mobile negative-pressure vacuum sweeper, fixing dry type dust suction unit, fixing wet type dust suction device group.
Vehicular the aspiration of negative pressure car has mobility strong, feature that dust suction negative pressure is higher, but roots blower air quantity is little, and dust removal ability is obviously not enough, and device structure is complicated, and stored program controlled is loaded down with trivial details, purchases with operation expense also high.
The mode that fixing dry type dust collecting device adopts cyclone dust removal and bag-type dust to combine mostly.Be characterized in that efficiency of dust collection is high, exhaust emissions is up to standard, the high needs meeting dust suction operating mode of blower negative pressure.But deduster feed bin limited volume, when inhaling a large amount of dust, discharge need be shut down in midway; During sack cleaner Inlet dust excessive concentration, cause filter bag blowback frequent breakage too fast, increase operating cost and maintenance.Roots blower noise is large, and maintenance cost is high.
Fixing wet type dust exhaust apparatus adopts wet cyclome and Multi-stage spiral wet scrubber mostly.Dust suction process can ash discharge continuously, and plant maintenance amount is little, and fan delivery is large, can open multiple suction inlet work simultaneously.
All there are different pluses and minuses in the aspiration of negative pressure mode that power plant commonly uses, does not also have a kind of method namely to meet need of production, be convenient to plant maintenance again.The present invention adopts centrifugal principle of negative pressure, and can realize the continuous ash discharge of high negative pressure, plant maintenance amount is little, and fan delivery is large, can open multiple suction inlet work simultaneously, be a kind of more satisfactory boiler the aspiration of negative pressure processing scheme, can reach the object of dust suction.
Summary of the invention
Order of the present invention is: provide a kind of power plant boiler body dust collection method, fix dust suction processing technological flow by negative pressure centrifugal blower and power plant current existing routine to combine, form a set of new power plant boiler body dust collecting process flow and method, boiler of power plant dust can be really effectively addressed, reduce manpower and plant maintenance amount, finally reach the object of economic dust suction.
The object of the present invention is achieved like this:
The present invention discloses a kind of power plant boiler body dust collection method, combine primarily of negative pressure centrifugal blower, sack cleaner and cyclone separator, it is characterized in that: the dust on boiler plant passes through boiler negative pressure dust-absorbing pipeline through cyclone separator, carry out one-level meal to be separated with foreign material, the dust of removing 75%; Deduster lower flashboard door synchronously installs electrical control cubicles, controls lock gate hatch opening and closing discharge dust with stuff level switch; Residue dust enters sack cleaner and carries out secondary separation, efficiency of dust collection 99.9%; Tail gas is discharged to flue (electrostatic precipitator entrance) through negative pressure centrifugal blower.
The present invention has following advantage and actively useful effect:
This device adopts centrifugal principle of negative pressure, can realize the continuous ash discharge of high negative pressure.Match centrifugal dust absorption fan.Technical characterstic is: dust suction process can ash discharge continuously, and plant maintenance amount is little, and fan delivery is large, can open multiple suction inlet work simultaneously.A kind of power plant boiler body dust collection method of the present invention, use the existing technical equipment in market, installed by one combination, be connected in the existing the aspiration of negative pressure processing technological flow of power plant, take full advantage of power plant's prior art equipment, power plant's dust can effectively be processed, and it is low that the present invention has cost of investment, the advantage of practicality more more economical than conventional boiler the aspiration of negative pressure disposal methods is a kind of more satisfactory boiler the aspiration of negative pressure processing scheme.
Now by reference to the accompanying drawings concrete structure of the present invention is described in detail with preferred embodiment:

5. negative pressure centrifugal blower
Detailed description of the invention
Please refer to shown in Fig. 1, a kind of power plant boiler body dust removal process method, combine primarily of negative pressure centrifugal blower, sack cleaner and cyclone separator, it is characterized in that: the dust on boiler plant through cyclone separator by boiler negative pressure dust-absorbing pipeline, is carried out one-level meal and is separated with foreign material; Deduster lower flashboard door synchronously installs electrical control cubicles, controls lock gate hatch opening and closing discharge dust with liquid-level switch; Residue dust enters sack cleaner and carries out secondary separation; Tail gas is discharged to flue (deduster entrance) through negative pressure centrifugal blower.
The service condition of above-described embodiment:
One, purposes
A kind of power plant boiler body dust collection method of the present invention can be connected to power plant and fix in dust suction treatment process, has treatment of Power dust more expeditiously and reaches the purposes of dedusting.
