Description
Technical field
The utility model relates to a kind of retracting device, particularly relates to a kind of retracting device fume afterheat being carried out to energy recovery.
Background technology
In industrial processes
,often boiler and industrial furnace can be installed, for production and processing provides thermal source.But all have a large amount of high temperature or low-temperature flue gas directly to enter air in the back-end ductwork of these boilers or industrial furnace, not only cause the pollution of environment, and heat energy is wasted in vain.
Summary of the invention
The purpose of this utility model is to provide a kind of self-circulation type heat-energy recovering apparatus, mainly solves flue gas in existing boiler or industrial furnace back-end ductwork and directly enters air, and contaminated environment also causes the problem of energy waste.
The utility model will be taked following technical measures to realize: this utility model comprises flue gas heat-exchange unit, by arranging elevated tank, be connected with down-comer through tedge respectively between elevated tank with flue gas heat-exchange unit, the two ends of described tedge and down-comer are respectively equipped with shut-off valve, also drain valve is provided with between described down-comer and flue gas heat-exchange unit, and hot water outlet pipe is set on described elevated tank, cold water filling pipe, overflow pipe, blow-off pipe and corresponding described hot water outlet pipe, cold water filling pipe, hot water effluent's valve set by blow-off pipe, cold water water compensating valve, drain valve.
The utility model has the following advantages and good effect:
1, energy-efficient; This device utilizes the difference in height of elevated tank and flue gas heat-exchange unit, makes water produce Natural Circulation, without any need for outer power, while acquisition heat energy, will save power source consumption again.
2, flexible arrangement; This device both can directly be arranged in boiler exhaust gas feed channel, or on various industrial furnace high-temperature exhaust emission pipeline, obtain high temperature heat, also can be arranged in after boiler economizer, air preheater, obtain low temperature heat energy, and can according to exhaust smoke level how many and temperature height flexible design flue gas heat-exchange unit and elevated tank capacity, be applicable to various high-temperature gas discharge occasion.
3, structure is simple; The flue gas heat-exchange unit structure of this device is simple, and can be designed to the version that square, circle etc. match with exit flue, this device adopts open system with no pressure, and the Steel material consumption of flue gas heat-exchange unit, elevated tank presses closed system than greatly reducing with having.
4, environmental; This device obviously can reduce the temperature of flue gas and reduce the discharge of dust after flue gas heat-exchange unit heat exchange, thus reduces the larger harm brought environment.
5, easy to operate; This device heat cycles is the Natural Circulation formed by elevated tank, down-comer, flue gas heat-exchange unit, tedge, without the need to manual operation.Moisturizing is controlled by ball-cock assembly, and the use of hot water by Artificial Control or can adopt simple automatically control and facility.
Accompanying drawing explanation
Fig. 1 is the utility model overall structure schematic diagram.
Detailed description of the invention
Self-circulation type heat-energy recovering apparatus is as shown in Figure 1 at exhaust gases passes outlet built-in pipe shell heat exchanger and flue gas heat-exchange unit 1, elevated tank 4 is established in flue gas heat-exchange unit 1 tool certain altitude position, be connected with down-comer 3 through tedge 2 respectively between elevated tank 4 with flue gas heat-exchange unit 1, shut-off valve 9 is respectively equipped with the two ends of down-comer 3 at described tedge 2, 13 and 10, 12, between described down-comer 3 and flue gas heat-exchange unit 1, be provided with drain valve 11 simultaneously, and hot water outlet pipe 5 is set on described elevated tank 4, cold water filling pipe 6, overflow pipe 7, blow-off pipe 8 and corresponding hot water outlet pipe 5, cold water filling pipe 6, hot water effluent's valve 15 set by blow-off pipe 8, cold water water compensating valve 16, drain valve 14 is formed.
During the work of this device, high temperature (heat) flue gas is by arranging that the water in flue gas heat-exchange unit heats by the heat exchanger tube in flue gas heat-exchange unit 1, entered into by the water heated the elevated tank 4 having certain altitude difference with flue gas heat-exchange unit 1 by tedge 2, the water that in elevated tank 4, temperature is lower is entered in flue gas heat-exchange unit 1 by high temperature (heat) flue gas by down-comer 3.Water after heating enters elevated tank 4 by tedge 2 again, so circulates, and water is constantly heated.Hot water enters heating equipment by the hot water outlet pipe 5 being located at elevated tank 4 top or with in hot systems.Carry out moisturizing by cold water filling pipe 6 to elevated tank 4, its water level is controlled by ball-cock assembly.
