Abstract

The utility model relates to a flue gas waste heat recovery device which comprises a boiler and a chimney. An air outlet of the boiler is communicated with the chimney. The flue gas waste heat recovery device further comprises a tubular heat exchanger and a heat preservation water tank, wherein the tubular heat exchanger is arranged on a heat exchanger bracket; the air inlet end and the air outlet end of the tubular heat exchanger are respectively communicated with the chimney; a water inlet of the tubular heat exchanger is communicated with the lower part of the heat preservation water tank through a pipeline, and a water outlet is communicated with the upper part of the heat preservation water tank through a pipeline; a cold water inlet pipe is arranged at the upper end of the heat preservation water tank, and a water outlet pipe is arranged at the bottom part of the heat preservation water tank; and a hot water conveying pump is arranged on the water outlet pipe. The flue gas waste heat recovery device is thermally exchanged with cold water by fully utilizing the heat energy of discarded flue gas, converts the cold water into usable hot water, has high heat exchange efficiency and saves the energy sources for users.

Description

A kind of flue gas waste heat recovery apparatus
Technical field
The utility model relates to a kind of waste-heat recovery device, the retracting device of fume afterheat in specifically a kind of flue.
Background technology
Energy-saving and emission-reduction, low-carbon economy, recycling be the action of actively advocating in the world, electing at present, increasing oil-burning gas-fired boiler comes into operation.Boilers such as the heating furnace of metallurgy industry, coloured industry and mechanical processing industry, heat-treatment furnace, flue gas is lost in the atmosphere by flue, not only causes environmental pollution, has also wasted a large amount of heat energy that contain in the flue gas.
In order to improve rate of energy; usually air heat exchanger can be installed, the flue gas that enters flue passes through the air heat exchanger heat exchange, but because the limitation of air heat exchanger; the heat exchanger effectiveness that utilizes air heat exchanger to bring is lower, can not make full use of the heat energy of flue gas.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of heat exchange efficiency height, implements simple flue gas waste heat recovery apparatus.
In order to solve the problems of the technologies described above, the utility model is taked following technical scheme:
A kind of flue gas waste heat recovery apparatus, comprise boiler and chimney, the gas outlet of boiler is communicated with chimney, also comprise pipe heat exchanger, attemperater, pipe heat exchanger is loaded on the heat exchanger support, pipe heat exchanger inlet end and outlet side are communicated with chimney respectively, the water inlet of pipe heat exchanger by pipeline be communicated with the bottom of attemperater, delivery port is communicated with the top of attemperater by pipeline, attemperater upper end is provided with into that cold water pipe, bottom are provided with outlet pipe, and outlet pipe is provided with hot water supplying pump.
Fume pipe is communicated with chimney the inlet end of described pipe heat exchanger by advancing, the outlet side is communicated with chimney by going out fume pipe, and this advances to be provided with the heat exchanger volume control damper in the fume pipe.
Be provided with the chimney volume control damper that is positioned at the top of fume pipe into, goes out the fume pipe below in the described chimney.
Be equiped with the heat exchanger circulating pump on water inlet on the described pipe heat exchanger and the pipeline between attemperater.
The cold water pipe that advances of attaching is provided with benefit cold water device on the described attemperater.
The utility model utilizes the heat energy of the discarded high-temperature flue gas that body of heater such as boiler produces, this heat energy and cold water are carried out heat exchange makes cold water convert hot water to, can do resident living water or factory uses, not only turn waste into wealth, also reduced the pollution of high-temperature flue gas, played good environmental-protection function, saved the energy atmosphere, the heat exchange efficiency height is implemented simple.
Description of drawings
Accompanying drawing 1 is the utility model assembled conduit connection diagram.
The specific embodiment
For the ease of those skilled in the art's understanding, the utility model will be further described below in conjunction with accompanying drawing.
As described in accompanying drawing 1, a kind of flue gas waste heat recovery apparatus, comprise boiler and chimney 1, the gas outlet of boiler is communicated with chimney 1, also comprise pipe heat exchanger 2, attemperater, pipe heat exchanger 2 is loaded on the heat exchanger support 3, pipe heat exchanger 2 inlet ends and outlet side are communicated with chimney 1 respectively, the water inlet 21 of pipe heat exchanger 2 by pipeline be communicated with the bottom of attemperater, delivery port 22 is communicated with the top of attemperater by pipeline, attemperater upper end is provided with into that cold water pipe 4, bottom are provided with outlet pipe 5, and outlet pipe 5 is provided with hot water supplying pump 12.Fume pipe 6 is communicated with chimney 1 inlet end of pipe heat exchanger 2 by advancing, the outlet side is communicated with chimney 1 by going out fume pipe 7, and this advances to be provided with heat exchanger volume control damper 8 in the fume pipe 6, is convenient to control the exhaust gas volumn that enters in the pipe heat exchanger 2.In chimney 2, also be provided with and be positioned at above the fume pipe 6 into, go out the chimney volume control damper 9 below the fume pipe 7, be convenient to the discharge capacity that the staff controls flue gas.
On the pipeline between water inlet on the pipe heat exchanger 2 21 and attemperater, be equiped with heat exchanger circulating pump 10.For convenient additional cold water, the cold water pipe 4 that advances of attaching is provided with benefit cold water device 11 on the attemperater.
The utility model makes full use of high-temperature flue gas, heat energy and cold water that high-temperature flue gas is comprised carry out heat exchange, make cold water convert hot water to, can make domestic water or offer factory to use, the heat exchange efficiency height, energy utilization rate is strong, reduced of the pollution of discarded flue gas to atmosphere, play good environmental-protection function, saved the energy, reduced the production cost of enterprise.
