The heat transfer area with box inner wall normal water is violently managed in a plurality of flue gas dust removal pipe multiplicable flue gas dust removal desulfurization area of design and flue gas and heat transfer. The utility model discloses simple structure, environmental protection and energy saving still effectively utilize its waste heat in the time of to flue gas dedusting and desulfurizing.
Description
Technical field
This utility model relates to fume dust remover, is specifically related to a kind of fume afterheat and utilizes and dust-removing desulfurating apparatus.
Background technology
Flue gas is typically directly discharged in air after dedusting, but usually contains substantial amounts of heat in flue gas, and flue gas is discharged its contained heat and be can not get effectively utilizing after dedusting, cause the waste of resource.
Summary of the invention
This utility model is for solving prior art problem, it is provided that a kind of device the most effectively utilizing its waste heat while to flue-gas dust-removing and desulfurization.
The technical solution adopted in the utility model is: a kind of fume afterheat utilizes and dust-removing desulfurating apparatus, including with the casing of smoke inlet, flue gas ash removal pipe, chimney, the dividing plate of band circular hole it is provided with in described casing, dividing plate is positioned at the lower section of smoke inlet, flue gas ash removal pipe upper port is connected with the circular hole on dividing plate, chimney is placed through dividing plate, and box bottom is provided with drawer type dedusting tank, and the lower port of flue gas ash removal pipe and chimney is respectively positioned on above the peak level of dedusting tank.
Further, described casing is made up of outer wall and inwall, and outer wall constitutes water storage cavity with inwall, and water injection pipe communicates with cavity, and the outer wall of casing is additionally provided with outlet.
Further, having additional one group of heat transfer transverse tube in described casing, heat transfer transverse tube two ends are connected with the inwall of opposite sides respectively, and the inner chamber of heat transfer transverse tube is connected with the water storage cavity of casing.
Further, the quantity of described heat transfer transverse tube is 3 ~ 5.
Further, described dedusting tank is provided with drainage screen.
It is convenient that what this utility model obtained has the beneficial effect that drawer type dedusting tank changes water, while flue gas is carried out dust-removal and desulfurizing, keeps the cleaning of water in tank at any time.The design of multiple flue gas ash removal pipes can increase flue-gas dust-removing and desulfurization area and flue gas and the heat exchange area of water in heat transfer transverse tube and cabinet wall.This utility model simple in construction, environmental protection and energy saving, to the most effectively utilizing its waste heat while flue-gas dust-removing and desulfurization.

Detailed description of the invention
With specific embodiment, this utility model is described in further detail below in conjunction with the accompanying drawings
As shown in Figure 1, a kind of fume afterheat utilizes and dust-removing desulfurating apparatus, including with the casing of smoke inlet, flue gas ash removal pipe 1, chimney 2, the dividing plate 3 of band circular hole 8 it is provided with in casing, dividing plate 3 is positioned at the lower section of smoke inlet, and flue gas ash removal pipe 1 upper port is connected with the circular hole 8 on dividing plate 3, and chimney 2 is placed through dividing plate 3, box bottom is provided with the drawer type dedusting tank 4 of band drainage screen 10, and the lower port of flue gas ash removal pipe 1 and chimney 2 is respectively positioned on above the peak level of dedusting tank 4.Casing is made up of outer wall (5) and inwall 6, and outer wall 5 and inwall 6 constitute water storage cavity, and water injection pipe 7 communicates with cavity, and the outer wall 5 of casing is additionally provided with outlet.Having additional 3 heat transfer transverse tubes 9 in casing, heat transfer transverse tube 9 two ends are connected with the inwall 6 of opposite sides respectively, and the inner chamber of heat transfer transverse tube 9 is connected with the water storage cavity of casing.
Specifically implement: the water storage cavity that water enters in casing from water injection pipe 7, with in heat transfer transverse tube 9, fills suitable quantity of water in dedusting tank 4.Flue gas enters in casing from smoke inlet, then enter into from the circular hole 8 of dividing plate 3 in flue gas ash removal pipe 1, due to the heat exchange of heat between water and the flue gas in heat transfer transverse tube and water storage cavity, flue gas is tentatively turned cold, part dust granules in flue gas just drops in dedusting tank 4, when flue gas arrives the water surface of dedusting tank 4, the residue dust granules in flue gas is just dissolved in water, will not be discharged in air.Sewage can be filtered by the drainage screen 10 of dedusting tank 4, and it is convenient that drawer type dedusting tank 4 changes water, keeps the cleaning of water at any time, and purified gas enters into air from chimney 2, clean environmental protection.Heated water can be used for heating etc., makes full use of the heat that burning produces, and substantially increases the utilization rate of fuel, saves the energy, avoids waste.
