A water outlet end of a heat exchanger of the cyclic production device is connected to a water inlet end of a hot water temperature adjustor. A water outlet end of the hot water temperature adjustor is connected to a user's water inlet end. A user's water outlet end is connected to an inlet of a hot water circulating pump, and an outlet of the hot water circulating pump is connected to a water inlet end of the gas-water heat exchanger. The whole cyclic production device is provided with water temperature monitoring and automatic adjustment system. The cyclic production device is capable of reusing industrial flue waste heat to produce constant-temperature hot water, so that the hot water is used for uses needing hot water, such as refrigerating, heating and bathing, and great economic benefit and social benefit are achieved.
Description
Technical field
The utility model relates to a kind of device that utilizes the heating furnace flue residue heat to produce constant-temperature hot water.
Background technology
Unit such as Metallurgical Enterprise, steam power plant can produce a large amount of waste heat flue gases when steel billet heating or boiler heating, temperature is about 500-700 ℃.For energy-saving and cost-reducing, when the design heating furnace, generally in flue, all be designed with air preheater, preheater is heated to combustion air that to send into heating furnace about 500 ℃ combustion-supporting.About 400 ℃ of the flue-gas temperature of air preheater rear end, a large amount of waste heats that this part flue gas carries often are not utilized, and enter in the atmosphere through chimney.
Summary of the invention
Be not utilized to present heating furnace waste heat flue gas, cause the problem of energy waste, the utility model provides a kind of device that utilizes the heating furnace flue residue heat to produce constant-temperature hot water.
Technical scheme is; In the flue of heating furnace, air-water heat exchanger is installed; The outlet pipe of this air-water heat exchanger links to each other with hot water temperature's adjuster through valve, draws a hot water feeding pipe from hot water temperature's adjuster and links to each other with the user, at this feed pipe appropriate location mounting temperature sensor; Temperature sensor links to each other with frequency converter through lead, and frequency converter links to each other with hot water temperature's adjuster through lead, and the user water side links to each other with the air-water heat exchanger water inlet end through hot water circulating pump through pipeline.All pipeline appearances all are laid with thermal insulating warm-keeping layer.
Heat exchanger absorbs the heat of flue gas, and water is wherein passed through in heating, supplies with the user and uses.The required hot water temperature of user can set as required, and comes to confirm and design the correlation technique index of heat exchanger in view of the above, to reach the coupling of heat supply and demand.Temperature sensor is the required hot water temperature of monitor user ' at any time, and when its hot water temperature is higher than design temperature, frequency converter will transmit signal to thermoregulator automatically, and thermoregulator will command its built-in system operation to realize heat radiation and finally make water temperature reach setting value.The constant-temperature hot water of producing; Water is pumped into user's (hot-water type Australia clang refrigeration unit, heating unit or other heat exchangers etc.); The water that the user uses the back temperature to reduce gets into the water inlet end of water pump, and the vapor-water heat exchanger that pressurization is sent in the flue reclaims fume afterheat, so constantly circulation.
The beneficial effect of this practical property is, the flue residue heat of industry is recycled, and produces constant-temperature hot water; And then with this hot water realize freezing, heating, having a bath etc. needs other purposes of hot water; Reduced the discharging of heat energy, practiced thrift energy resource consumption, good economic benefits and social benefit have been arranged.
Description of drawings
Accompanying drawing is the technology arrangement sketch map of the utility model.
Among the figure, 1 is hot water circulating pump; 2 is hot water temperature's adjuster; 3 is air-water heat exchanger; 4 is the hot water outlet pipe; 5 is safety valve; 6 is hot water return pipe; 7 is underground flue; 8 is the hot water feeding pipe; 9 is user's outlet pipe; 10 is the user; 11 is frequency converter; 12 is temperature sensor;
The specific embodiment
Air-water heat exchanger 3 is installed in the underground flue 7 of heating furnace; The outlet pipe 4 of this air-water heat exchanger links to each other with hot water temperature's adjuster 2 through valve; Draw a hot water feeding pipe 8 from hot water temperature's adjuster and link to each other, at this feed pipe appropriate location mounting temperature sensor 12 with user 10; Temperature sensor links to each other with frequency converter 11 through lead, and frequency converter links to each other with hot water temperature's adjuster 2 through lead, and the user water side links to each other with the air-water heat exchanger water inlet end through hot water circulating pump 1 through user's outlet pipe 9.All pipeline appearances are provided with thermal insulating warm-keeping layer.
Heat exchanger absorbs the heat of flue gas, and water is wherein passed through in heating, supplies with the user and uses.User 10 required hot water temperatures can set as required, and come to confirm and design the correlation technique index of heat exchanger in view of the above, to reach the coupling of heat supply and demand.Temperature sensor 12 is the required hot water temperature of monitor user ' at any time; When its hot water temperature is higher than design temperature; Frequency converter 11 will transmit signal automatically to thermoregulator 2, and thermoregulator will command its built-in system operation to realize heat radiation and finally make water temperature reach setting value.The constant-temperature hot water of producing; Deliver to user 10 (hot-water type Australia clang refrigeration unit, heating unit or other heat exchangers etc.) by water pump; The water that the user uses the back temperature to reduce gets into the water inlet end of hot water circulating pump 1, and the vapor-water heat exchanger that pressurization is sent in the flue 7 reclaims fume afterheat, so constantly circulation.
Between turn(a)round, air-water heat exchanger aggregate erection in flue of modular is good at heating furnace through inspection manhole, and carry out the water pressure test with pressuring pump, leakage must not be arranged, all hot water pipeline outer surfaces lay thermal insulating warm-keeping layer.Because Large-scale Heater all is to move all the year round, have only several days repair time general every year, so system must debug normal before heat exchanger is not installed, hot water circulating pump is wanted the using and the reserved, and can automatically switch.
