Technical field
The invention belongs to field of environment protection; particularly relate to the smoke and dust eliminating technology in the field of environment protection; comprise by many dedusters of custom-designed cigarette air channel associated mode, air-introduced machine and cyclone impact type wet water membrane smoke purification device and cooperatively interacting; be connected in series between burner (or boiler) and the fume extractor (or chimney), and constitute a kind ofly brand-new do, gas cleaning new technology that wet method matches.
Background technology
Become since environmental protection since the fundamental state policy of China, the environmental protection cause of China has obtained developing rapidly, especially all kinds of green technology products that have independent intellectual property right emerge in an endless stream especially, cyclone dust collector is arranged in filed of flue gas purification especially, multi-tube dust cleaner, sack cleaner, impingement dust collector, water film type duster or the like is innumerable, and cyclone dust collector, sack cleaner and multi-tube dust cleaner belong to the dry method dust category, impingement dust collector and water film type duster belong to the wet dedusting category, when using separately, above-mentioned deduster all has bigger limitation and the problem that self is difficult to overcome to some extent, as when containing the gas cleaning of gaseous state and solid-state multiple polluter, because dry dust removal can not desulfurization and is removed the gaseous contamination material, so, can not satisfy the requirement of the existing standard limit of smog release of China, except that simple dedusting, generally not use; When independent use wet scrubber carries out gas cleaning, also exist the wet corrosion of blower fan and equipment and wet scrubber self problem such as obstruction easily, and cause a lot of troubles; When pollutant purification being required the mode that adopts multistage dedusting is also arranged when high especially, but when adopting multistage dedusting, resistance is increased exponentially, strengthen energy consumption, except that special requirement, generally also not be used for overcoming resistance.In the process of common smoke abatement and dust control, generally all use single device for eliminating smoke and dust, because air-introduced machine and deduster relative position is different, have forced again and branch suction-type, as air-introduced machine being placed the front end of deduster, we are referred to as forced dedusting method, and air-introduced machine is placed the rear end of deduster, and we are referred to as suction-type dedusting fraction.For handling the big flue gas of dustiness, those irregular particles very easily cause the dry wear to fan blade, so, usually dust arrester generally adopts the suction-type dedusting method, but, for hydrofilter, employing suction-type dedusting method is easy to generate the appearance to problems such as the wet corrosion of blower fan and equipment and obstructions again.In sum, these defectives that existing dedusting technology self exists are necessary to improve, and the present invention proposes a kind of two-stage cyclone impact type wet water membrane smoke purification method, can address the above problem preferably.
Embodiment
More than we sum up existing dedusting technology, can reduce following some:
1) nonaqueous dust cleaner be owing to can not remove the polluter of gaseous state, when for purification the ash-laden gas of gaseous contamination material being arranged, must take hydrofilter as needs desulfurization etc.
2) for purifying high dust content, when having gaseous contaminant again, we use hydrofilter, irregular particle thing in the flue dust is to the dry wear of blower fan, we can not use forced dedusting method, when having to take the suction-type dedusting method, then produce the wet corrosion of blower fan and equipment again inevitably and easily cause the appearance of deduster self blockage problem.
3) if only utilize prior art simply, front end at air-introduced machine is provided with a nonaqueous dust cleaner, in the rear end of air-introduced machine one hydrofilter is set, just can not address the above problem? but thing followed problem is a resistance to be multiplied thereupon, has brought unnecessary energy loss and waste.So whether to have under the situation of not obvious increase resistance, solve the scheme of above-mentioned technical barrier preferably? target that the present invention pursued that Here it is, realize that the concrete technical scheme of the technology of the present invention target is:
A kind of two-stage cyclone impact type wet water membrane smoke purification method that cooperatively interacts and constituted by many dedusters of cigarette air channel associated mode, air-introduced machine and cyclone impact type wet water membrane smoke purification device, many dedusters of described cigarette air channel associated mode, air-introduced machine and cyclone impact type wet water membrane smoke purification device are through the custom-designed requisite environmental protection gas cleaning auxiliary facility that is connected in series between burner (or boiler) and the fume extractor (or chimney); Described air-introduced machine is the power resources that produce flow of flue gas in this auxiliary facility; Describedly be connected in series and be divided into forced and two kinds of methods of attachment of suction-type.Here it should be noted that also that for the resistance that reaches the two-stage dedusting only is equivalent to the resistance effect of primary dust removing in the past, the design of many dedusters of cigarette air channel associated mode and cyclone impact type wet water membrane smoke purification device all is a lower resistance.
