Abstract
The invention discloses a dust collector for the slag discharging system of a boiler. The dust collector comprises an impact dust collector, a bottom slag chamber, an air inlet pipe, a discharge pipe and a dust collector hood mounted at the top of the bottom slag chamber. The discharge ports of the discharge pipe are arranged in the dust collector hood at the top of the bottom slag chamber, the air inlet pipe is connected with the impact dust collector, and the air inlets of the air inlet pipe are arranged in the dust collector hood. The dust collector is characterized in that the air inlets are arranged beside the discharge ports, and a cloth curtain is arranged at the periphery of the dust collector hood. Generally, three air inlets and three air discharge ports are mounted at the top of the bottom slag chamber. The blower fan of the impact dust collector can be mounted on the ground to reduce vibration. The inventive dust collector is simple in structure, and low in construction cost and operation maintenance cost, allows high dust content at the inlet, and can purify dust of given viscosity without causing clogging.
Description
Technical field
The present invention relates to a kind of dust arrester, particularly relate to a kind of dust arrester that is used for the CFBB dreg removing system.
Background technology
Show that according to data about 60% belongs to pellet in the flue dust of discharged from coal-fired boiler, promptly PM10 is the PM2.5 bigger to human harm greatly and have in the middle of this.Pellet, promptly PM10 is meant diameter≤10 μ m, can get into the particle of people's respiratory system; PM2.5 then is meant the particle of diameter in the atmosphere≤2.5 μ m, is also referred to as and can goes into the lung particle, and the source mainly is the burning of ore fuel such as coal.Contain noxious materials such as heavy metal among the PM2.5 mostly, particularly serious to human harm, therefore; Reduce near the PM2.5 content of CFBB dreg removing system as far as possible; The safe and stable operation of support equipment, employee and near resident's is healthy, has crucial meaning.
The dust pollution of thermal power plant is the topic that all circles pay close attention to always.Behind the burning in circulating fluid bed boiler, produce a large amount of lime-ash,, be difficult to guarantee that near the air-borne dust concentration with the boiler slag removal system is controlled in the critical field if deal with improperly with the generation amounts of dust.To fundamentally eliminate dust pollution, will walk the route of the comprehensive regulation, start with, select advanced reasonably plant equipment for use, be aided with certain dustproof, dust suppression from production equipment.But under the current working condition of thermal power plant, effective measures still improve cleaner.The selection of cleaner will be considered the aspects such as character of desired degree of purification of operation site and dust.A lot of for the application study of disintegrating scrubber both at home and abroad, but aspect CFBB dreg removing system treating flour dust, still adopt fiber bag precipitator or filter cartridge dust remover mostly.
The general every cloth bag of will changing a time at a distance from 3 to 6 months of fiber bag precipitator, maintenance workload is big, and efficiency of dust collection is low.Filter cartridge dust remover is not suitable for handles the dust that contains air-water mixture, can stop up the filtering holes on the filter cylinder, and it is high to change the filter cylinder cost, and maintainer's workload is big.
Summary of the invention
The purpose of this invention is to provide a kind of boiler slag removal system dust removing device, so that Maintenance and Repair and maintenance cost are cheap.
Boiler slag removal system dust removing device of the present invention; Comprise between disintegrating scrubber, end slag, intake stack, discharge nozzle and dust shield, dust shield is installed in top between end slag, the discharging opening of discharge nozzle is arranged between end slag in the dust shield of top; Intake stack is connected with disintegrating scrubber; The air inlet of intake stack is arranged in the dust shield, it is characterized in that said air inlet is arranged on the discharging opening next door, is provided with the door curtain made of cloth around said dust shield.
Usually, the top between end slag is equipped with 3 air inlets and 3 discharging openings.
The blower fan of disintegrating scrubber can be installed on the ground, to reduce vibration.
When the slag dumping of slag storehouse; Disintegrating scrubber is started working simultaneously; Dusty gas between end slag directly is drawn into intake stack and gets in the disintegrating scrubber body from top air inlet between end slag; Discharge via blower fan through purification, dedusting, after removing water droplet, near the door curtain made of cloth between the end slag discharging opening is used to prevent that dusty gas is to external diffusion again.On each discharging opening side an air inlet is set, can improves dust removing effects.
Dust arrester of the present invention is simple in structure, and is cheap, and operation and maintenance cost is low, and has and allow the inlet dust content high, and can purify the dust of certain viscosity and advantage such as can not stop up.
Description of drawings
Fig. 1 is the structural representation of the embodiment of the invention.
Fig. 2 is the upward view of dust shield among Fig. 1.
The specific embodiment
Introduce embodiments of the invention in detail below in conjunction with accompanying drawing.
The structure of boiler slag removal system dust removing device such as Fig. 1, shown in Figure 2; Comprise between disintegrating scrubber 14, end slag 11, intake stack 13, discharge nozzle 15 and dust shield 19, dust shield 19 is installed in top between end slag, the discharging opening 16 of discharge nozzle 15 is arranged between end slag in the top dust shield 19; Intake stack 13 is connected with disintegrating scrubber 14; The air inlet 17 of intake stack 13 is arranged in the dust shield 19, and air inlet 17 is arranged on discharging opening 16 next doors, is provided with the door curtain made of cloth 12 around the dust shield 19.Simultaneously the blower fan 18 of disintegrating scrubber 14 is installed on the ground.
When the slag dumping of slag storehouse; Disintegrating scrubber 14 is started working simultaneously; Dusty gas in 11 between end slag is drawn into intake stack 13 and gets in disintegrating scrubber 14 bodies from the air inlet 17 of dust shield 19; Pass through purification, dedusting, remove after the water droplet, discharge via blower fan 18, near the door curtains made of cloth 12 between end slag 11 discharging openings 16 are used to prevent that dusty gas is to external diffusion.
In addition, air inlet and discharging opening can also be set to a plurality of, with the dust removing effects of further raising to interior dusty gas between end slag, prevent that dusty gas from overflowing.
Claims (3)
1. boiler slag removal system dust removing device; Comprise between disintegrating scrubber, end slag, intake stack, discharge nozzle and dust shield, dust shield is installed in top between end slag, the discharging opening of discharge nozzle is arranged between end slag in the dust shield of top; Intake stack is connected with disintegrating scrubber; The air inlet of intake stack is arranged in the dust shield, it is characterized in that said air inlet is arranged on the discharging opening next door, is provided with the door curtain made of cloth around said dust shield.
