Abstract

The invention discloses a heat-exchange dedusting device. The heat-exchange dedusting device comprises a shell, wherein a connecting device is arranged at the lower end of the shell; the connecting device is provided with a hot air inlet; a water inlet is formed on the lower part of the shell; a separating baffle is arranged in the shell; a cold water area is formed between the shell and the separating baffle; a warm water area is formed in the separating baffle; an upper smog chamber is arranged on the upper part of the shell, and a lower smog chamber is arranged on the lower part of the shell; the lower smog chamber is provided with a fume outlet; and a dedusting device is arranged in the separating baffle. The heat-exchange dedusting device can be used as the upper half body of a boiler and also can connect the smoke outlet of the boiler with the fume inlet of the connecting device, most heat in hot fume is absorbed by water, and dust in the fume is removed by the dedusting device at the same time, so that the dual aims of surplus heat utilization and environmental emission are fulfilled.

Description

The heat exchange dust arrester

Technical field

The invention belongs to environmental protection equipment, relate in particular to a kind of heat exchange dust arrester that integrates UTILIZATION OF VESIDUAL HEAT IN and dedusting.

Background technology

Various heat-exchange devices are arranged at present both at home and abroad, and its function all is single, and effect is not very good, and the dust in the heat-exchange device smog of especially using on the boiler can not be removed, and pollutes to air.Some producer has also made various switches for the attainment of one's purpose, and its cost is too high, and the result of use still misses one's aim.

Summary of the invention

The purpose of this invention is to provide a kind of heat exchange dust arrester, can when absorption contains the heat in the hot gas, remove the dust in the gas.

For realizing above-mentioned purpose, the present invention adopts following technical scheme: a kind of heat exchange dust arrester, comprise housing, and there is jockey the housing lower end; Hot air intake is arranged on the jockey, and lower housing portion has water inlet, and the separation dividing plate is arranged in the housing, and housing is a cold water area with separating between dividing plate; Separating in the dividing plate is the warm water district, and the smog chamber is attend on housing top, and lower housing portion has following smog chamber, in the following smog chamber exhanst gas outlet is arranged; Separating in the dividing plate has dust arrester, and the dust arrester below has dedusting mouth, dust arrester top that isolation interlayer back-up ring is housed, and isolating in the interlayer back-up ring is the hydrothermal area; The outlet flue of dust arrester is positioned at isolates interlayer back-up ring center, and outlet flue communicates with last smog chamber, separates to also have heat pipe in the dividing plate, and the lower end of heat pipe communicates with hot air intake; Smoke-box is equipped with on the top of dust arrester, and the upper end of heat pipe communicates with smoke-box, and smoke-box communicates with the inner chamber of dust arrester through the mouth of pipe; Connecting leg one end communicates with the warm water district, and the connecting leg other end communicates with the hydrothermal area, and cold water area and warm water district are communicated with by water-supply-pipe; The upper end of attached heat pipe communicates with last smog chamber, and the lower end of attached heat pipe communicates with following smog chamber, and an end of tube connector communicates with the hydrothermal area.

Described dust arrester is a cyclone separator.

One end of tube connector communicates with hydrothermal area's top.

Adopt the heat exchange dust arrester of technique scheme; The upper semi-body that can be used as boiler uses; Also can the outlet flue of boiler and the gas approach of jockey be joined; The heat overwhelming majority in the hot flue gas is absorbed by water, and the dust in the flue gas is also removed by dust arrester simultaneously, has reached the dual purpose of UTILIZATION OF VESIDUAL HEAT IN and environment protection emission.

Description of drawings

Fig. 1 is a structural representation of the present invention.

Fig. 2 is that the A-A of Fig. 1 is to view.

The specific embodiment

Like Fig. 1, heat exchange dust arrester shown in Figure 2, comprise housing 1, there is jockey 11 the housing lower end, and hot air intake 12 is arranged on the jockey 11; Lower housing portion has water inlet 14, and the dividing plate 7 of separation is arranged in the housing, and housing 1 is a cold water area 16 with separating 7 on dividing plate; Separating in the dividing plate is warm water district 15, and smog chamber 20 is attend on housing top, and lower housing portion has following smog chamber 22; In the following smog chamber exhanst gas outlet 13 is arranged, separating in the dividing plate has dust arrester 4, and there is dedusting mouth 9 the dust arrester below; Dust arrester top is equipped with and is isolated interlayer back-up ring 23, and isolating in the interlayer back-up ring is hydrothermal area 3, and the outlet flue 19 of dust arrester is positioned at isolates interlayer back-up ring center; Outlet flue 19 communicates with last smog chamber 20, separates to also have heat pipe 5 in the dividing plate, and the lower end of heat pipe communicates with hot air intake 12; Smoke-box 18 is equipped with on the top of dust arrester, and the upper end of heat pipe 5 communicates with smoke-box 18, and smoke-box 18 communicates with the inner chamber of dust arrester through the mouth of pipe 2; Connecting leg 17 upper ends communicate with warm water district 15, and connecting leg 17 lower ends communicate with hydrothermal area 3, and cold water area 16 is communicated with by water-supply-pipe 21 with warm water district 15; The upper end of attached heat pipe 8 communicates with last smog chamber 20, and the lower end of attached heat pipe 8 communicates with following smog chamber 22, and an end of tube connector 10 communicates with hydrothermal area 3 top.

Dust arrester 4 can adopt cyclone separator, or adopts other the equipment with dedusting function.

The present invention is the cold water area 16 of cold water entering heat-exchange device in use; Water is up to the top and gets into water-supply-pipe 21 upper ends; The water-supply-pipe lower end is warm water district 15, and water enters into the hydrothermal area 3 who isolates in the interlayer back-up ring from top, warm water district through connecting leg 17 then, in this process; The heat that cold water absorbs in the flue gas becomes hot water, and hot water is transported to the hot equipment of using from the hydrothermal area upper end through tube connector 10.

The present invention is joined the outlet flue of boiler and the gas approach of jockey in use, and the hot flue gas that boiler produces rises and gets into heat pipe 5; Be transported to smoke-box 18 by heat pipe 5; Flue gas in the smoke-box gets into dust arrester 4 through the mouth of pipe, and flue gas is attend smog chamber 20 through the dust arrester dedusting after outlet flue 19 gets into, and the flue gas of last smog chamber is transported to down smog chamber 22 by attached heat pipe 8; Enter chimney by exhaust opening 13; In this process, the heat in the flue gas is absorbed by water gradually, and the flue-gas temperature that enters chimney is very low; Flue gas is discharged by the dedusting mouth through dust arrester dust kicked up by somebody walking in front slag.Also can the water tank that have upper boiler now be taken away, and the present invention is used as the upper semi-body of boiler.
