Dust arrester.
Background technology
In China's industrial furnace, the industrial furnace proportion with coal as fuel is relatively big, accounts for whole nation work
The 64% of industry stove sum.It is micro-that the flue gas that coal-fired industry furnace is discharged contains more white carbon black, dust etc.
Fine particle, containing noxious substances such as more harmful heavy metals in these fine particles, sternly
Heavily contaminated air quality, endangers resident healthy.
At present, the medium-scale industrial furnace overwhelming majority has been mounted with cleaner on flue, the most often
Have sack cleaner and electrostatic precipitator.Sack cleaner is moderate, but its floor space is wide,
Power consumption is big, and filter bag often needs to change, and later maintenance is costly.Electrostatic precipitator then needs charged system
System grading design is to remove the grit of different-grain diameter, it is therefore desirable to use labyrinth to improve removal efficiency,
With high costs.Also there are some Industrial Stoves to be mounted with water dust scrubber on flue, but form moisture film and need
Relatively big yield, is suitable for the place near sufficient water source, and power consumption is the highest, and water is seriously polluted, after
Phase water processing cost is high.Therefore, today of energy-conserving and environment-protective is vigorously advocated in country, it is necessary to propose one
Plant low cost, the dust arrester that removal efficiency is high.

Being provided with plenum chamber, two micro hole spraying pipes are connected by plenum chamber, near the water jacket of blower fan be provided with
The water inlet that upper hose is connected;It is provided with out fume pipe near the top of a micro hole spraying pipe of water tank side,
And outside the water jacket of this side, it is provided with the outlet being connected with downcomer.
Being provided with header tank at gas collection component bottom, header tank is connected with water tank by soil pipe.
From blower fan to collection pneumatic module enter to be sequentially provided with on the pipeline of fume pipe the first stop valve and gas stream
Gauge.
Collection pneumatic module to be sequentially provided with on the downcomer pipeline of water tank Pressure gauge, fluid flowmeter, second
Stop valve and non-return valve.
It is additionally provided with circulating pump on downcomer pipeline between non-return valve and water tank.
It is provided with filter screen in described water tank;Overflow pipe and filler pipe, overflow pipe and filler pipe it is additionally provided with on water tank
It is provided with spilling water valve and priming valve respectively.
Compared with prior art, the present invention has a following useful technique effect:
Flue gas introducing is collected pneumatic module, gas collection by blower fan by the micro-hole jet formula sleeve pipe dust arrester of the present invention
Assembly forms water circulation loop with water tank, forms the Automatic Cycle of water, and the consumption of water is the lowest, collection
Several micro hole spraying pipes in pneumatic module are externally provided with water jacket, and in water jacket, current can penetrate into fume pipe
On aperture, form multiply cross jet, increase the contact area of flue gas and jet water column, by flue gas
Fine particle washes clean.The present invention can effectively remove the fine particle in flue gas, it is to avoid clear
Secondary pollution during clean water, fine particle removal efficiency is high, compact conformation, energy-conservation, environment is friendly
Good.
