Abstract
The invention provides boiler tail gas dust and smoke removal equipment which comprises a sulfur removal device, wherein one end of the sulfur removal device is connected with an industrial boiler, and the other end of the sulfur removal device is connected with one end of a cooling device by virtue of an exhaust fan; the other end of the cooling device is connected with one end of a dust removal system; the other end of the dust removal system is connected with the lower end of a smoke extraction machine; and the upper end of the smoke extraction machine is connected with one end of the industrial boiler. The boiler tail gas is recycled and burned back, the technical problems that the tail gas emission of the industrial boiler is difficult to solve, the emission does not reach the standard and the like are solved, and the equipment is energy-saving and environmentally friendly.
Description
Technical field
The present invention relates to a kind of boiler exhaust gas dedusting smoke eliminating equipment.
Background technology
When Industrial Boiler needs to heat up, coal, firewood, diesel oil etc. are generally used as fuel, these fuel are in combustion process
In, need the appropriate fresh air of increase to help burn, make fuel combustion abundant.Fully combustion has just been burned in current various fuel
During burning, substantial amounts of carbide can be produced（Dirt）With substantial amounts of dense smoke.It is inefficient with traditional wet treatment method,
Discharging standards are not reached, this makes numerous environment-friendly engineering technical staff that headache is felt for this.Industrial Boiler exhaust emissions is difficult to resolve
Certainly, the technical barrier such as not up to standard is discharged.
The content of the invention
In order to overcome the defect of prior art, the present invention to provide technical scheme below：
A kind of boiler exhaust gas dedusting smoke eliminating equipment, it includes desulfurizing device, and its one end is connected with Industrial Boiler, and the other end leads to
Cross air exhauster to be connected with one end of device for cooling, the other end of the device for cooling connects with one end of dust pelletizing system
Connect, the other end of the dust pelletizing system is connected with the lower end of smoking machine, the upper end of the smoking machine connects with one end of Industrial Boiler
Connect.
Further, the lower end of the heat sink and the lower end of dust pelletizing system are all connected with some fume recovery bags.
Further, the device for cooling is made up of some cooling blowers.
Further, some dust-removal cloth-bags, dust-removal cloth-bag top connection pneumatic pressure pulses device are set in the dust pelletizing system.
Tail gas produced by boiler combustion carries out after sulphur removal, conveying tail gas by air exhauster by pipeline by desulfurizing device
Carry out after cooling down to device for cooling, then pass through pipeline and tail gas is transported in dust pelletizing system, tail gas passes through dedusting
After dust-removal cloth-bag in system, microgranule, dust in tail gas etc. can by dust-removal cloth-bag lattice from and be bonded at dust-removal cloth-bag outside or
In the fume recovery bag 7 dropped to below dust pelletizing system, the tail gas through multiple tracks dust-removal cloth-bag lattice after is discharged after dust pelletizing system,
It is displaced in the port of Industrial Boiler by smoking machine 5 again and is flashed back again.
From above-mentioned operation principle, the beneficial effect that the present invention is brought is：Recycle boiler exhaust gas to flash back again, solve
Industrial Boiler exhaust emissions of having determined be difficult to resolve certainly, discharge the technical barrier such as not up to standard, energy-conserving and environment-protective.
Description of the drawings
Fig. 1 is schematic structural view of the invention.
Specific embodiment
Presently preferred embodiments of the present invention is described in detail below in conjunction with the accompanying drawings, so that advantages and features of the invention energy
It is easier to be readily appreciated by one skilled in the art, apparent clearly defines so as to make to protection scope of the present invention.
As shown in figure 1, a kind of method and its equipment that allow boiler exhaust gas to circulate the dedusting smoke abatement that flashes back again, it includes that sulphur removal is filled
2 are put, its one end is connected with Industrial Boiler 1, the other end is connected by air exhauster 6 with one end of device for cooling 3, the cooling
The other end of chiller is connected with one end of dust pelletizing system 4, and the other end of the dust pelletizing system 4 connects with the lower end of smoking machine 5
Connect, the upper end of the smoking machine 5 is connected with one end of Industrial Boiler 1.Under the lower end of the heat sink and dust pelletizing system 4
End is all connected with some fume recovery bags 7.The device for cooling 3 is made up of some cooling blowers 8.In the dust pelletizing system 4
Some dust-removal cloth-bags 9 are set, and the top of dust-removal cloth-bag 9 connects pneumatic pressure pulses device 10, the vibrating dust removing cloth bag 9 of pneumatic pressure pulses device 10
Cigarette is dropped in lower section fume recovery bag 7 through the grit that the surface of dust-removal cloth-bag 9 is stayed in after dust-removal cloth-bag 9, flue gas is discharged and removed
Send with charge free in Industrial Boiler after being collected by smoking machine 5 again after dirt system 4 and burn again, reach the purpose of the combustion product gases that move in circles.
The operation principle of embodiment of the present invention is：Tail gas produced by boiler combustion is removed by desulfurizing device 2
After sulfur, tail gas is transported to device for cooling 3 by air exhauster 6 by pipeline carries out after cooling down, then passing through pipeline handle
Tail gas is transported in dust pelletizing system 4, after tail gas is through the dust-removal cloth-bag 9 in dust pelletizing system 4, the meeting such as microgranule, dust in tail gas
By the lattice of dust-removal cloth-bag 9 from and be bonded at the outside of dust-removal cloth-bag 9 or drop to the lower section of dust pelletizing system 4 fume recovery bag 7 in, pass through
Tail gas of the lattice of multiple tracks dust-removal cloth-bag 9 after is discharged after dust pelletizing system 4, then is displaced in the port of Industrial Boiler by smoking machine 5
Flashed back again.
Embodiment of the present invention this have the advantage that：Recycle boiler exhaust gas to flash back again, solve Industrial Boiler tail
Gas discharge be difficult to resolve certainly, discharge the technical barrier such as not up to standard, energy-conserving and environment-protective.
The above, the only specific embodiment of the present invention, but protection scope of the present invention is not limited thereto, any
Those of ordinary skill in the art disclosed herein technical scope in, the change that can expect without creative work or
Replace, all should be included within the scope of the present invention.Therefore, protection scope of the present invention should be limited with claims
Fixed protection domain is defined.
