Abstract
The utility model discloses a kind of heat recovery device of acidizing fired relieving haperacidity fluidized bed furnace outlet flue gas, comprise the fluidized bed furnace, flue and the cyclone dust collectors that connect in turn, wherein, also comprise that drum and some internal diameters are less than the heat exchange pipeline of flue, described heat exchange pipeline is uniform or be spirally coiled in the outer wall of flue along the circumferencial direction of flue; The import and export of described heat exchange pipeline is connected with drum by transmission pipeline.This device is by setting up some heat exchange pipelines that are connected with drum at flue outer wall, the heat that can make flue is absorbed to remove by heat exchange pipeline and with drum, is converted to steam and discharges afterwards, these steam can be for the heating of factory's life or industrial water, and heating use in winter etc., saved the energy.
Description
Technical field
The utility model belongs to heat recovery technical field, is specifically related to a kind of heat recovery device of acidizing fired relieving haperacidity fluidized bed furnace outlet flue gas.
Background technology
In the acidizing fired relieving haperacidity production technology of aurin powder, normal open piping carrys out the temperature of cooled flue gas.As shown in Figure 1, in prior art, the flue-gas temperature of fluidized bed furnace 1 outlet is at 550～560 ℃ and contain a large amount of steam and dust, after flue 2 natural heat dissipations coolings, dedusting, treat that flue-gas temperature is down to 350～380 ℃ of technological requirements that just can reach cyclone dust collectors 3 and follow-up electric cleaner.If flue-gas temperature easily causes burning out of pipeline and high temperature corrosion higher than said temperature; If flue-gas temperature lower than said temperature, easily causes the dew point corrosion of pipeline, cyclone dust collectors and follow-up equipment such as electric cleaner.Due to flue-gas temperature higher (550～560 ℃), if high-temperature flue gas is only cooled to 350～380 ℃ through natural heat dissipation in pipeline, the flue needing is first long, second also causes a large amount of thermal waste.
Utility model content
The utility model object is to overcome prior art defect, and a kind of heat recovery device of acidizing fired relieving haperacidity fluidized bed furnace outlet flue gas is provided.
For achieving the above object, the utility model adopts following technical scheme:
A kind of heat recovery device of acidizing fired relieving haperacidity fluidized bed furnace outlet flue gas, comprise the fluidized bed furnace, flue and the cyclone dust collectors that connect in turn, wherein, also comprise that drum and some internal diameters are less than the heat exchange pipeline of flue, described heat exchange pipeline is uniform or be spirally coiled in the outer wall of flue along the circumferencial direction of flue; The import and export of described heat exchange pipeline is connected with drum by transmission pipeline.
Preferably, when heat exchange pipeline is uniform along the circumferencial direction of flue, the axis of described heat exchange pipeline parallels with the axis of flue.For guaranteeing the security of the long-time circular flow of drum, the water in drum is preferably used desalted water, can effectively avoid like this fouling in pipeline.Water at low temperature in drum enters heat exchange pipeline, and is heated after flue heat exchange, and the water after heating enters after drum again, and part is converted into steam by the carbonated drink separation equipment in drum and discharges.
Compared to the prior art, the beneficial effects of the utility model:
By set up some heat exchange pipelines that are connected with drum at flue outer wall, the heat that can make flue is absorbed to remove by heat exchange pipeline and with drum, is converted to steam and discharges afterwards, these steam can be for the heating of factory's life or industrial water, and heating use in winter etc., saved the energy.Use this device; can by flue natural heat dissipation, change into and utilize heat exchange pipeline absorption remove the heat shedding and be converted into steam with drum existing; in flue heat radiation; the waste heat that effectively recovered flue gas pipeline sheds; cyclone dust collectors and the follow-up equipment such as electric cleaner have not only been protected; also realize recycling of the energy, there is good economic and social benefit.
Accompanying drawing explanation
Fig. 1 is the structural representation of existing apparatus;
Fig. 2 is the structural representation of device described in the utility model;
Fig. 3 be in device described in the utility model heat exchange pipeline at the distribution schematic diagram of flue outer wall.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further details, but protection domain of the present utility model is not limited to this.
embodiment 1
As shown in Figures 2 and 3, a kind of heat recovery device of acidizing fired relieving haperacidity fluidized bed furnace outlet flue gas, comprise the fluidized bed furnace 1, flue 2 and the cyclone dust collectors 3 that connect in turn, wherein, also comprise that drum 7 and some internal diameters are less than the heat exchange pipeline 4 of flue 2, described heat exchange pipeline 4 is uniform along the circumferencial direction of flue 2; The import of described heat exchange pipeline 4 is connected with drum 7 outlets by the first transmission pipeline 5, and the outlet of described heat exchange pipeline 4 is connected with drum 7 imports by the second transmission pipeline 6.When heat exchange pipeline 4 is uniform along the circumferencial direction of flue 2, the axis of described heat exchange pipeline 4 parallels with the axis of flue 2.
In production process, the flue gas (temperature is at 550～560 ℃) of fluidized bed furnace 1 outlet enters flue 2, low temperature desalted water in drum 7 enters heat exchange pipeline 4 through the first conveyance conduit 5, with flue 2 heat exchanges after be heated that (simultaneously the flue-gas temperature in flue 2 is reduced to 350～380 ℃, met the technological requirement of cyclone dust collectors 3 and follow-up electric cleaner), water after heating enters after drum 7 again through the second conveyance conduit 6, and part is converted into steam 8 by the carbonated drink separation equipment separation in drum 7 and discharges.These are converted steam 8 after recovery can be for the heating of factory's life or industrial water, and heating in winter used etc., has saved the energy.
It should be noted last that: above-described embodiment is only illustrative rather than definitive thereof the technical solution of the utility model; any the utility model is carried out be equal to modification or local replacement of replacing and not departing from the utility model spirit and scope, within it all should be encompassed in the scope of the utility model claim protection.
