Abstract

The utility model relates to a dust and sulfur removing apparatus for purifying boiler flue gas, which comprises dust and sulfur removing purifying chambers, a purifying liquid feeding device, a water spray pipe and a dehydrator, dust and sulfur removing purifying chambers are manly and have vertical type multi-layer structures; a flue gas inlet of a shell wall is connected with a mouth and is inserted into the purifying liquid; the water spray pipe arranged on the upper part of the purifying chamber is connected with the purifying liquid feeding apparatus; a flue gas discharging port is connected with the dehydrator through a pipeline; the sulfur removing agent adopts the purifying liquid formed by mixing sodium carbonate with water. Because the utility model adopts a plurality of dust and sulfur removing purifying chambers having vertical type multi-layer structures, the structure is compact and simple, and the efficiency high; when the utility model works, boiler flue gas rushes into the purifying liquid for bubbling; the boiler flue gas is sprayed as secondary dust and sulfur removal; thereby, the purifying effect is good.

Description

The New-type boiler desulfurating dust removing device for flue gas

The utility model belongs to environmental protection machinery, mainly is meant a kind of New-type boiler desulfurating dust removing device for flue gas that is suitable for various Industrial Boilers, kiln institute smoke discharging are carried out purified treatment.

Defectives such as existing boiler fume desulfurizing and dedusting device adopts dry type cyclone dust removal, the abundant spray desulfurization of water, centrifugal gas-water separation classification treatment process more, exists structure complicated, and floor space is big, and the power consumption high efficiency is low.

The goal of the invention of the utility model is for overcoming the deficiency of prior art, prior art is improved, provide a kind of desulfurization and dedusting that collects in a Room, adopting the New-type boiler desulfurating dust removing device for flue gas of secondary water-bath technology.

The utility model is so to implement, a kind of New-type boiler desulfurating dust removing device for flue gas, comprise and have the into desulfurization dust separation chamber of mouth and exhaust opening, the scavenging solution liquid feed device, the scavenging solution spray header, and dehydrator etc. is partly formed, be characterised in that, described desulfurization dust separation chamber has a plurality of, become vertical multi-ply construction, the branched pipe that advances cigarette house steward (4) connects each clean room's shell wall and advances mouth (5), advancing mouth taps into cigarette and chews (6) and insert in the scavenging solution (15), each chamber spray header (9) connection connects the scavenging solution feed liquor mouth of pipe (8), and the exhaust opening (12) on each shell wall top, chamber connects dehydrator (13) by smoke discharging pipe.

Of the present utility modelly advance in the best oblique insertion scavenging solution of Yan Zui (6), and advance Yan Zui and be provided with porous comb petticoat pipe (16).

The utility model combines in a Room with desulfurization and dust collecting process, and device is simplified, vertical multilayer, and the efficient height takes up an area of and economizes, and flue gas pours earlier in the scavenging solution, and the water surface of emerging is then sprayed, through the dedusting of secondary water bath desulfurization, good purification.

Accompanying drawing 1 the utility model front view

Accompanying drawing 2 the utility model advance cigarette and chew comb petticoat pipe front view

Elaborate below in conjunction with the structure of drawings and Examples to the utility model:

Accompanying drawing one is the structure front view of an embodiment of the utility model, it comprises the desulfurization dust chamber (2) of a plurality of independent operatings, become the vertical structure of multilayer up and down, constitute a vertical desulfurization dust separation tower (1), can make single desulfurization dust chamber earlier during making, admittedly welding one again forms, also can weld dividing plate (3) in the box hat tower body admittedly forms, present embodiment is three layers of clean room, into mouth (5) is established at its shell wall middle part, each chamber, exhaust opening (12) is established on its top, shell wall is established water filling port (7) under the liquid level, sewage draining exit (11) is arranged at the bottom, shell wall is established gap (10) on the liquid level, and the desulfurizing and purifying liquid feed liquor mouth of pipe (8), advancing mouth taps into the cigarette arm outward and taps into cigarette total pipeline (4) again, in tap into cigarette and chew (6) and insert in the scavenging solution, advancing cigarette chews in the preferably oblique insertion scavenging solution, present embodiment advances cigarette and chews and liquid level angle at 45, and cigarette is chewed and is provided with porous comb petticoat pipe, flue gas is loose by cover hole comb to be entered in the scavenging solution, increase solid-liquid contact area and time, improve clean-up effect, the external smoke evacuation arm of shell wall top, clean room exhaust opening (12), be connected with dehydrator (13) air inlet through the smoke evacuation house steward again, spray header (9) is fixed in indoor top, each chamber spray header connection connects the scavenging solution feed liquor mouth of pipe (8), connect the water pump and the scavenging solution water tank of liquid feed device by pipeline, scavenging solution is desulfurizing agent to be converted water make alkalies, present embodiment adopts sodium carbonate to convert water and makes the desulfurization alkalies that pH value is 8-9, be transported to each clean room's spray header by water pump, chew ejection, (also can adopt the boiler blow-off alkaline water) by its tube wall sputter.Boiler smoke is chewed towards in desulfurization dust chamber's scavenging solution by advancing cigarette earlier, most of dust is deposited at the bottom of the chamber, the flue gas of being emerged by bubbling in the scavenging solution is subjected to alkali lye to swash spray by force then, so through secondary response processing procedure in scavenging solution and in the spray process, sulfur-containing oxide (mainly being sulfur dioxide) and the sodium sulfite that alkali lye (sodium carbonate) reflection generates are separated out, and make the exhaust gas dust precipitation, and the flue gas that contains hazardous substance is cleaned, reach the purpose of removing sulfur and dust and eleminating smoke.The flue gas that is cleaned enters centrifuge dehumidifier by exhaust opening through pipeline, makes gas-water separation, separates after-purification gas and is discharged through chimney by dehydrator exhaust outlet (14).Desulfurization dust chamber's bottom precipitation thing is regularly discharged by water filling port (7) waterflood flush and by sewage draining exit (11).During enforcement, advance cigarette and chew with spray header and should be made by stainless steel material, container inner wall should be done preservative treatment.
