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, generally use coal, firewood, diesel oil etc. as fuel, these fuel in combustion, need to increase appropriate fresh air and help burning, make fuel combustion abundant.Just be burned in clean-burning process at current various fuel, a large amount of carbide (dirt) and a large amount of dense smoke can have been produced.By traditional wet treatment method, efficiency is not high, does not reach discharging standards, and this makes numerous environment-friendly engineering technical staff feel headache for this reason.The technical barriers such as Industrial Boiler exhaust emissions is difficult to resolve certainly, discharge is not up to standard.
Summary of the invention
In order to overcome the defect of prior art, the invention provides following technical scheme:
A kind of boiler exhaust gas dedusting smoke eliminating equipment, it comprises desulfurizing device, its one end is connected with Industrial Boiler, the other end is connected with one end of device for cooling by air exhauster, the other end of described device for cooling is connected with one end of dust pelletizing system, the other end of described dust pelletizing system is connected with the lower end of smoking machine, and the upper end of described smoking machine is connected with one end of Industrial Boiler.
Further, the lower end of described heat sink and the lower end of dust pelletizing system all connect some fume recovery bags.
Further, described device for cooling is made up of some cooling blowers.
Further, in described dust pelletizing system, some dust-removal cloth-bags are set, above dust-removal cloth-bag, connect pneumatic pressure pulses device.
After the tail gas that boiler combustion produces carries out sulphur removal by desulfurizing device, by air exhauster, tail gas is transported to after device for cooling carries out cooling down by pipeline, then by pipeline, tail gas is transported in dust pelletizing system, tail gas is through after the dust-removal cloth-bag in dust pelletizing system, particulate in tail gas, dust etc. can by dust-removal cloth-bag lattice from and in the outside that is bonded at dust-removal cloth-bag or the fume recovery bag 7 dropping to below dust pelletizing system, through multiple tracks dust-removal cloth-bag lattice from after tail gas discharge after dust pelletizing system, flash back again in the port being displaced into Industrial Boiler again by smoking machine 5.
From above-mentioned operation principle, the beneficial effect that the present invention brings is: recycle boiler exhaust gas and flash back, solves the technical barriers such as Industrial Boiler exhaust emissions is difficult to resolve certainly, discharge is not up to standard, energy-conserving and environment-protective.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present invention is described in detail, can be easier to make advantages and features of the invention be readily appreciated by one skilled in the art, thus more explicit defining is made to protection scope of the present invention.
As shown in Figure 1, a kind of boiler exhaust gas that allows circulates the method for dedusting smoke abatement and the equipment thereof of flashing back again, it comprises desulfurizing device 2, its one end is connected with Industrial Boiler 1, the other end is connected with one end of device for cooling 3 by air exhauster 6, the other end of described device for cooling is connected with one end of dust pelletizing system 4, and the other end of described dust pelletizing system 4 is connected with the lower end of smoking machine 5, and the upper end of described smoking machine 5 is connected with one end of Industrial Boiler 1.The lower end of described heat sink and the lower end of dust pelletizing system 4 all connect some fume recovery bags 7.Described device for cooling 3 is made up of some cooling blowers 8.In described dust pelletizing system 4, some dust-removal cloth-bags 9 are set, pneumatic pressure pulses device 10 is connected above dust-removal cloth-bag 9, pneumatic pressure pulses device 10 vibrating dust removing cloth bag 9 drops to cigarette in below fume recovery bag 7 through the grit staying dust-removal cloth-bag 9 surface after dust-removal cloth-bag 9, flue gas is sent with charge free in Industrial Boiler after being collected by smoking machine 5 after discharging dust pelletizing system 4 again and is burnt, reaches the object of the combustion product gases that moves in circles.
The operation principle of embodiment of the present invention for: after the tail gas that boiler combustion produces carries out sulphur removal by desulfurizing device 2, by air exhauster 6, tail gas is transported to after device for cooling 3 carries out cooling down by pipeline, then by pipeline, tail gas is transported in dust pelletizing system 4, tail gas is through after the dust-removal cloth-bag 9 in dust pelletizing system 4, particulate in tail gas, dust etc. can by dust-removal cloth-bag 9 lattice from and in the outside that is bonded at dust-removal cloth-bag 9 or the fume recovery bag 7 dropping to below dust pelletizing system 4, through multiple tracks dust-removal cloth-bag 9 lattice from after tail gas discharge after dust pelletizing system 4, flash back again in the port being displaced into Industrial Boiler again by smoking machine 5.
The advantage that embodiment of the present invention has is: recycle boiler exhaust gas and flash back, solves the technical barriers such as Industrial Boiler exhaust emissions is difficult to resolve certainly, discharge is not up to standard, energy-conserving and environment-protective.
The above; be only the 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 are in the technical scope disclosed by the present invention; the change can expected without creative work or replacement, all should be encompassed within protection scope of the present invention.Therefore, the protection domain that protection scope of the present invention should limit with claims is as the criterion.
