Description
Technical field
The present invention relates to the smoke and dust purifier of a kind of smoke and dust purifier, particularly middle and small burn coal boiler.
Background technology
Along with the development of society, the environmental consciousness of people is more and more stronger, the control of atmosphere pollution has been become to the important topic of people's common concern, and the tail gas of coal-burning boiler is as one of air primary pollution source, is especially paid attention to.At present, large coal-fired boiler in all parts of the country is a lot, for the tail gas dust treatment of large coal-fired boiler, the wet dedusting technology of general employing, better dust removal effect, but some associate devices such as blower fan, hydrofilter will be increased, relative cost is higher, and occupied ground area is large, and for more be middle and small burn coal boiler, owing to considering cost factor, employing rate is very low, at present, most small scall coal-fired boiler does not take effective purifying and dedusting measure.
Summary of the invention
In order to change the deficiencies in the prior art, the invention provides a kind of coal-burning boiler smoke and dust purifier, when lower cost, the purifying problem of middle and small burn coal boiler flue dust can be solved preferably.
The technical solution adopted in the present invention is: auto-induction type coal-burning boiler smoke and dust purifier comprises funnel body, corrosion-inhibiting coating, baffle plate, spray head, spray head connecting rod, flue dust inductor, water-supply-pipe, small sized high-pressure water pump, filter screen, slagging-off wicket, sump pit, clear water reserviors, Calcified pond, sedimentation basin, described funnel body inwall scribbles corrosion-inhibiting coating, described spray head is fixed on funnel body inner top center by spray head connecting rod is vertically unsettled down, described spray head connecting rod is connected with water-supply-pipe through chimney wall, described small sized high-pressure water pump is placed in clear water reserviors, spray head is connected by water-supply-pipe and spray head connecting rod, described baffle plate is placed in directly over funnel body inner flue entrance, be fixed on chimney wall obliquely, floss hole is flowed into for preventing water smoke, described flue dust inductor is fixed on the chimney wall below spray head, be electrically connected with small sized high-pressure water pump control circuit, induction by flue dust controls the work of small sized high-pressure water pump, described filter screen is placed in chimney bottom, above it, chimney wall has slagging-off wicket, for removing the flue dust filter residue on filter screen, described sump pit connects chimney bottom and sedimentation basin below filter screen, liquid after strainer filtering is discharged in sedimentation basin by sump pit, described sedimentation basin has gap to be connected with clear water reserviors by filter screen, described Calcified pond top is also connected with clear water reserviors by filter screen.
Further, described spray head and spray head connecting rod are more than two covers or two covers, and to make for the anticorrosive material such as stainless steel or plastics, and between every two spray heads interval height between 40cm to 60cm.
Further, described spray head connecting rod is fixed on chimney wall in chimney wall place by connecting rod fixed head sealing bolt.
Further, described baffle plate is that heat-resistant anticorrosive material is made.
Further, described flue dust inductor embeds in chimney wall, and have waterproof above its induction end, be positioned at chimney, the other end stretches out and is fixed on chimney outer wall.
The beneficial effect that the present invention brings is: the limewash in described Calcified pond arrives clear water reserviors after precipitation and strainer filtering, then through small sized high-pressure water pump and water-supply-pipe, spray head connecting rod, sprayed by spray head, soot dust granule and sulfur-bearing carbon containing pernicious gas in absorption chimney, leach flue dust residue by filter screen afterwards, be discharged in sedimentation basin, after sedimentation and filtration through sump pit, unnecessary limewash returns clear water reserviors, can recycle.Described spray head is in chimney top, and is two or more, spray multilayer lime water smoke out, and the time contacted with flue dust when falling under gravity is longer, the better effects if of particle and pernicious gas in absorption flue dust.Described flue dust inductor according to the presence or absence sensing flue dust in chimney, can control small sized high-pressure water pump operating circuit break-make by control circuit, reaches and automatically control object.Apparatus structure is simple, and less expensive is easy to operate.
