CN201543352U - Barrel type smoke filter for coal fired boilers - Google Patents

Abstract

The utility model discloses a barrel type smoke filter for coal fired boilers, which is a wet smoke-dust eliminator used for coal fired boilers, in particular to miniature vertical coal fired boilers. The barrel type smoke filter for coal fired boilers is characterized in that a waist part is provided with a dark bottom; and the upper part of the barrel type smoke filter for coal fired boilers is coaxially provided with a smoke guide pipe sleeve, a conic titanium screen filter element and a cylindrical nylon screen filter element; the lower part of the barrel type smoke filter for coal fired boilers is provided with a spiral core cartridge and one circle of spiral fins; the smoke-gas communicating pipes and discharge pipes of the upper and the lower parts are formed at the external part of the barrel type smoke filter for coal fired boilers by using semi-circle pipes leaning to rely against the barrel body. As a spiral core cartridge, spiral fins and a barrel body form the structure of a PW cyclone dust eliminator, smoke and gas discharged by boilers using the filter does not contain dust or moisture.

Description

Drum type fire coal boiler fume filter

Affiliated technical field

The wet method smoke prevention and dust control device that the utility model relates to a kind of coal-burning boiler is particularly to the wet method smoke prevention and dust control device of minitype vertical type coal-burning boiler.

Background technology

Existing wet method smoke prevention and dust control device to the minitype vertical type coal-burning boiler, how to do cleaning dust by the pond on ground or the container of other sealings with the function of air-introduced machine, only accomplish disposable cleaning dust, often because pond or seal of vessel bad still be that flue dust is billowing, and the flue gas that air-introduced machine is discharged usually is with water.

Summary of the invention

The purpose of this utility model is exactly the drum type wet method smoke prevention and dust control device that a kind of metallic article will be provided, and goes to finish cleaning dust, dust removal by filtration and gas-water separation to flue gas with simple structure smaller volume.The utility model is that the technical scheme that its technical problem of solution is adopted is: establish a dark end between the waist of drum type device for abatement of smoke and dust, make staving become two spaces that equate up and down; Being provided with flue gas guiding socket at the top concentric, serves as to establish tapered titanium gauze net filter core in the support with this socket; Peripheral hardware cylinder type mud dragon gauze net filter core; Be provided with a helix core tube and a circle flight at the bottom concentric; Rely on staving to constitute that passage is ganged up in the flue gas transfer and fume emission is ganged up passage in the outside of staving with the semicircle pipe; Concentric is provided with ash-laden gas and enters pipe on bung; Feed pipe is located at ash-laden gas and enters on the pipe; Two places respectively established about the sewage overflow pipe divided, and supported whole staving with three supporting legs and got final product.

The beneficial effects of the utility model are: for the once washing dedusting of in the less circular staving of volume, accomplishing ash-laden gas, and a cyclone dust removal, the dedusting of twice gauze filter element filtering, so dust removing effects can be better, the gas-water separation effect can be better.

Description of drawings

Below in conjunction with accompanying drawing (schematic diagram) the utility model is described in further detail.

In the accompanying drawings, Fig. 1 is a version schematic diagram of the present utility model.Fig. 2 is the A-A sectional drawing of Fig. 1.Fig. 3 is an application schematic diagram of the present utility model.

In Fig. 1: 1 drum type staving, 2 bungs are at the bottom of 3 barrels, the dark end between 4 staving waists, 5 ash-laden gas guiding socket, 6 tapered 30 order titanium gauze net filter cores, 7 cylinder types, 30 order mud dragon gauze net filter core, 8 flights, 9 helix core tubes, pipe is ganged up in 10 flue gas transfers, 11 fume emissions are ganged up pipe, and 12 ash-laden gas enter pipe, 13 dustless smoke discharge tubes, 14 feed pipes, (can be desulfurization and dedusting as recirculated water) with buck or limewash; Overflow pipe on 15,16 times overflow pipes, 17 supporting legs.Flue gas guide pipe (5) wherein, tapered 30 order titanium gauze net filter cores (6), cylinder type 30 order mud dragon gauze filter core (7), bung (2) belongs to removable sections, organizes a performance with screw, buckle (not label).Arrow is represented the flow of flue gas direction among the figure.

The specific embodiment

When boiler (accompanying drawing 3.3) was lighted a fire, air-introduced machine (accompanying drawing 3.4) started simultaneously, and the hot flue gas of dust-laden enters the internal upper part of drum type fire coal boiler fume filter (accompanying drawing 3.1) through fume hot-water device (accompanying drawing 3.2).Feed pipe in accompanying drawing Fig. 1 (14) feeds water simultaneously, and ash-laden gas and water are impacting tapered 30 order titanium gauze net filter cores (6) jointly, and filter core (6) is carried out interception to flue dust, flue gas is kept letting slip, and water has the Washing effect to filter core.Last overflow pipe (15) can limit the drinking water situation of flue gas guiding socket (5), when in the wedging water of flue gas guiding socket (5) bottom, the prevention that is subjected to the pressure flue gas of atmosphere to have to blow open water removes to accept the secondary interception and the Washing of cylinder type 30 order mud dragon gauze net filter cores (7) together with the spray that blows afloat; Filtered smoke gas is ganged up pipe (10) through the flue gas transfer and is entered the bottom.Because helix core tube (9) and flight (8) and staving (1) have constituted the structure situation of PW cyclone dust collectors, so it has stronger cyclone dust removal ability and gas-water separation ability.Flue gas not moisture, not dust-laden is ganged up pipe (11) by fume emission and drain into atmosphere under the effect of air-introduced machine (accompanying drawing 3.4).

Claims (1)

1. wet method smoke prevention and dust control device that is used for coal-burning boiler, round metal barrel shape coal-burning boiler wet method smoke prevention and dust control device especially for the minitype vertical type coal-burning boiler, it is characterized in that establishing between the waist of this deduster a dark end (4) makes staving (1) become two spaces that equate up and down, be provided with flue gas guiding socket (5) at the top concentric, with this socket serves as to establish tapered titanium gauze net filter core (6) in the support, peripheral hardware cylinder type mud dragon gauze net filter core (7); Be provided with a helix core tube (9) and a circle flight (8) at the bottom concentric; Rely on staving to constitute that passage (10) is ganged up in the flue gas transfer and fume emission is ganged up passage (11) in the outside of staving (1) with the semicircle pipe; Be provided with ash-laden gas at the last concentric of bung (2) and enter pipe (12), feed pipe (14) is located at ash-laden gas and enters on the pipe (12); Two places respectively established about sewage overflow pipe (15,16) divided, and supported whole staving with three supporting legs (17) and got final product.
