Abstract
The utility model discloses a smoke deacidifying and dust remover. The top of a neutralization reactor (2) is provided with a centrifugal atomizer (1); a tangential smoke inlet (11) is arranged in the middle of the top of the neutralization reactor (2); a smoke outlet (8) is arranged on the top of the neutralization reactor (2); the lower part of the neutralization reactor (2) is connected with a sedimentation water tank (3), and the bottom of the sedimentation water tank (3) is provided with an automatic sewerage discharging valve (9). Lime slurry is sent to the centrifugal atomizer (1) by a lime slurry preparing system (7); atomized lime slurry is spouted in the neutralization reactor (2) by the high-speed rotation of the centrifugal atomizer (1) to be fully mixed with acidic smoke so as to carry out neutralization reaction. The remainder of the reaction falls into the sedimentation water tank (3); the automatic sewerage discharging valve (9) automatically discharges sewerage on time. Smoke after processed is discharged via the smoke outlet (8) after passing through an axial flow type centrifuge dehydrator (6). The smoke deacidifying and dust remover takes a plurality of sorts of deacidifying and dust removal technologies, and has the advantages of high degree of automatization, high deacidifying rate, low consumption rate of lime, reliable performance and convenient maintenance.
Description
Affiliated technical field
The utility model relates to a kind of deduster, especially removes the SO in the flue gas
2, HCl, HF, NO, NO
XDeacidifying flue gas deduster etc. the acidic gaseous pollutant.
Background technology
The kind of smoke duster is a lot of at present, in the environmental protection field of industry-by-industry, various smoke dusters are arranged, the performance of various smoke dusters, index and effect are all different, and the structure of common desulfurizing dust-collector generally is to set into mouth, outlet flue on housing.Utility model patent (the application number: 97212447) disclose a kind of dust-removing desulfurating apparatus of CN2322048Y bulletin, this dust-removing desulfurating apparatus is to be that a side of body shell is provided with smoke inlet at reactor, opposite side is provided with outlet flue, between smoke inlet and outlet flue, be provided with deduster, above deduster, be provided with fountain head, fountain head is connected with water pump, is provided with delivery port and sewage draining exit in the bottom of reactor.This deduster makes trouble, complex process, inconvenient maintenance.And the smoke duster with deacidification that provides on the market is less, but comprehensively adopt centrifugal spray, the equipment of multiple depickling dedusting technology such as counter-rotating acid-base neutralization, water-bath gather dust, axial-flow type centrifugal dehydration do not have.
Summary of the invention
The purpose of this utility model provides the multiple depickling dedusting technology of a kind of employing, the automaticity height, and deacidification rate height, lime consumption rate is low, dependable performance, deacidifying flue gas deduster easy to maintenance.
The technical solution of the utility model is: a neutralization reactor is set, the neutralization reactor bottom connects the precipitation water tank, outlet flue is located at the top of neutralization reactor, smoke inlet is located at the crown center of neutralization reactor, at the neutralization reactor top centrifugal atomizer is housed, the precipitation water tank bottom is equipped with sewage draining exit.
