Description
Technical field
The utility model relates to a kind of novel fuel boiler dust separation collection facility.
Background technology
In the flue gas that fuel boiler burning produces, containing a large amount of dust, these dust, must be separated, first collect in factory temporarily, then be sent to the special storage ash field arranged and deposit or fully utilize, otherwise be discharged in air, can to air and environment.
The facility of dust in fuel boiler separating flue is various dedusters, and in factory, the interim facility collecting it is grey storehouse.Existing deduster and Hui Ku are arranged apart.Deduster is arranged in boiler tail, and grey storehouse is then arranged in have other of certain distance local with deduster, and connecting both them is Pneumatic conveyer and ash pipeline line.The dust granules that deduster is separated, by Pneumatic conveyer, is delivered in grey storehouse by ash pipeline line and stores, then dry ash tank car is loaded with automobile bulk loader, or use dry ash humidifier, be mixed into humidification ash after adding water, transport grey field or comprehensive utilization place to dump truck.Supporting facility, has the built on stilts pipe support of the air compressor of conveying and air compressor chamber, support ash pipeline line, and corresponding electrical control facility.Whole set of installation energy consumption is high, and occupation of land is many, and the technical problem of existence is many, and trouble point is many, and cost is high.
Utility model content
The purpose of this utility model is to overcome the technical problem existed in existing fuel boiler dust separation collection facility, provide a kind of system simple, reduce energy consumption, Economization on land, fuel boiler dust separation collection facility that cost is low.
For achieving the above object, the utility model adopts following technical proposals:
A kind of fuel boiler dust separation collection facility, comprises the deduster, top dust collection layer, the middle part that set gradually from top to bottom and unloads grey mechanical floor and bottom automobile passage layer; Described top dust collection layer, middle part unload grey mechanical floor and the as a whole frame structure of bottom automobile passage layer; The grey storehouse be directly connected with deduster is provided with in described top dust collection layer, described deduster comprises multiple unit, wherein the bottom automobile passage layer of at least two unit is located in the ground above, and the bottom automobile passage layer of deduster subsequent cells, is located on the ground or underground.
Described top dust collection layer, middle part unload grey mechanical floor and bottom automobile passage layer adopts steel or reinforced concrete frame structure, and whole frame structure supports the deduster on top.
The grey storehouse be directly connected with deduster is provided with in described top dust collection layer.Described grey storehouse is made up of some groups of ash silos; Ash silo has ash silo first and ash silo second two kinds of forms, and ash silo first is square structure, and ash silo second is inverted cone-shaped structure; Ash silo first is provided with continuous material level meter, limit state meter, high charge level meter and manhole door, and ash silo second is provided with high charge level meter; All there is discharge port ash silo first and ash silo second bottom; The outside of ash silo first and ash silo second is provided with heat-insulation layer, and ash silo first and ash silo second adopt steel or Reinforced Concrete Materials.
Described ash silo first or You Hui storehouse, second bottom gasification blower fan, its outlet connects electric heater, electric heater outlet connects gasification wind mother pipe, and the female pipe of gasification wind is connected to several and gasification skewed slot or gasification board interconnective gasification wind arm, the grey storehouse gasification wind heating system of composition; Gasification skewed slot is that gradient shape is arranged.
Described deduster is the deduster of electrostatic precipitator, sack cleaner or other type, and the entrance point of deduster is connected with boiler by flue, and the port of export is connected to chimney by air-introduced machine.
The characteristic of electrostatic precipitator is: the dry ash amount that the first two electric field is collected is comparatively large, and the dry ash amount that rear several electric field is collected is less.In described fuel boiler dust separation collection facility, when adopting electrostatic precipitator, the first two electric field, that is the ash silo of the first two unit bottom is designed to square structure, in order to increase the storage volumes in grey storehouse.Rear several electric field, that is rear several unit because of ash quantity less, grey storehouse storage volumes does not need very large, and the ash silo of bottom is designed to inverted cone-shaped structure, taken up space to reduce.
The characteristic of sack cleaner is: the dry ash amount that each unit is collected is relatively more even, so when dust separation collection facility employing sack cleaner, and the square structure that the ash silo of each unit bottom is become volume consistent by Uniting.
The dry ash that deduster is collected, has good comprehensive utilization value, is widely used in every field.Described Hui Ku bottom, be separately installed with dry type discharge system and wet type discharge system.Dry type discharge system is connected with ash silo discharge port with wet type discharge system top, dry type discharge system is used for dry ash directly being loaded dry ash tank car and transports user to, become half wet shape ash after wet type discharge system is used for dry ash to mix with water to load dump truck and transport user to, two cover systems can meet the demand of different user respectively.
Dry type discharge system under described deduster the first two unit ash storehouse and wet type discharge system, be arranged on middle part and unload in grey mechanical floor.Dry type discharge system after described deduster under several unit ash storehouse and wet type discharge system, according to the difference of coupled ash silo structural shape, be arranged in different layers.When coupled ash silo structural shape is square, two kinds of discharge systems are arranged on middle part and unload in grey mechanical floor, when coupled ash silo structural shape is back taper, two kinds of discharge systems are arranged in the dust collection layer of top, can save lower space like this.
