The device has the advantages that the smoke heat exchanger is additionally arranged on an air delivery pipeline, and the primary smoke pipeline of the smoke heat exchanger is connected with the heat exchange branch mechanism in parallel, so the smoke residual heat of the brick kiln is furthest utilized, the waste at heat energy and the pollution to heat sources are avoided, and the requirements of heat energy and the utilization of residual heat of the production process are met.
Description
Technical field
The utility model relates to gangue brickkiln UTILIZATION OF VESIDUAL HEAT IN technical field, and what relate generally to is the residual heat using device of high-temperature flue gas in a kind of gangue brickkiln.
Background technology
In known gangue brick field production line, conventionally the flue gas of Cooling Section of Tunnel Kiln is delivered to dry kiln by air-introduced machine, the adobe of dry kiln is dried, realize UTILIZATION OF VESIDUAL HEAT IN.Because the flue-gas temperature of salband is up to 300-500 ℃, and the baking temperature of dry kiln only needs 140 ℃ of left and right, like this, a large amount of heat energy need be in transmitting procedure by cooling losing naturally, heat loss is up to more than 50%.Not only waste the energy, but also can cause, the thermal source of environment is polluted.
Summary of the invention
Task of the present utility model is the residual heat using device that proposes high-temperature flue gas in a kind of gangue brickkiln.By install flue gas heat-exchange unit additional on air supply duct, and the heat exchange branch mechanism that is connected in parallel on a circulating line of flue gas heat-exchange unit, reach the maximized brickkiln fume afterheat that utilizes, avoid thermal waste and thermal source to pollute, meet heat energy demand and UTILIZATION OF VESIDUAL HEAT IN in production technology.
The utility model is realized the technical scheme that above-mentioned task takes: a kind of gangue brickkiln flue gas waste heat utilization device, on gangue brickkiln flue, flue gas heat-exchange unit is set, on a circulating line of flue gas heat-exchange unit, be connected in parallel to one or more heat exchange branch mechanism, the heat exchanger by branch by the transfer of heat in circulation once in branch.
The heat exchange branch mechanism that the utility model is connected in parallel on a circulating line of described flue gas heat-exchange unit be bathing heat exchanger or/heating heat exchanger or/air-heater.
Flue gas heat-exchange unit described in the utility model is air-water heat exchanger.
The utility model is provided with by-pass flue on described gangue brickkiln flue, and is provided with Electric air valve on flue and by-pass flue.
The utility model by installing flue gas heat-exchange unit additional on gangue brickkiln flue, and be connected in parallel to heat exchange branch mechanism on a circulating line of flue gas heat-exchange unit, the cold water that enters heat transmission equipment is heated, after heat exchange, produce high-temperature-hot-water, be transported in heating and bath system, to substitute coal-burning boiler heating system by circulating pump again.High-temperature-hot-water is transported to heater by circulating pump in addition, produces hot blast blow to coal mine by warm-air drier.Flue gas after heat exchange is transported to former air supply duct, uses for dry kiln dry brick.By strengthening the Insulation of air inducing flue of calcining kiln, heat loss rate is reduced within 15%, avoid thermal waste and thermal source to pollute, effectively improve the comprehensive utilization of brickkiln fume afterheat, meet heat energy demand and UTILIZATION OF VESIDUAL HEAT IN in production technology.
Accompanying drawing explanation
Fig. 1 structural representation of the present utility model.
In figure: 1, Electric air valve, 2, flue gas heat-exchange unit, 3, flue, 4, water softener, 5, elevated tank, 6, bathing heat exchanger, 7, heating heat exchanger, 8, air-heater, 9, water circulating pump, 10, control valve.
The specific embodiment
By reference to the accompanying drawings, provide of the present utility model being implemented as follows:
Gangue brickkiln flue gas waste heat utilization device described in the present embodiment comprises the circulatory system being made up of flue gas heat-exchange unit 2, water circulating pump 9, water softener 4, elevated tank 5 and associated ping and control valve 10; The bathing hot-water heating system being formed with heat exchanger 6 and associated ping, valve by bathing; The hot-water central heating system being formed by heating heat exchanger 7 and associated ping, valve; The well head hot-air system being formed by air-heater 8 and associated ping, valve.
What flue gas heat-exchange unit 2 adopted is known air-water heat exchanger, and it is arranged on gangue brickkiln flue, and on flue, is provided with by-pass flue.On flue and by-pass flue, be provided with Electric air valve 1.Effect is according to the operation of waste-heat recovery device or halted state, automatically to adjust the runner of flue gas, and in the time that waste-heat recovery device moves, smoke gas flow carries out waste heat recovery through flue gas heat-exchange unit 2; In the time that waste-heat recovery device stops, smoke gas flow, through by-pass flue, reduces the loss to flue gas heat-exchange unit.The inlet end of elevated tank 5 is connected with running water through water softener 4, and what water softener 4 adopted is conventional known technology.The water outlet end of elevated tank 5 is connected with the inlet end of flue gas heat-exchange unit 2 through pipeline, the water outlet end of flue gas heat-exchange unit 2 is connected with inlet end circulation through water return pipeline, on its water return pipeline, be connected with water circulating pump 9 and control valve 10, its effect is to increase power and regulating action to circulation.
Multiple heat exchange branch systems in parallel and air-heater in a circulatory system, by this branch system of transfer of heat in once circulating, reach the maximized brickkiln fume afterheat that utilizes by heat exchanger, meets heat energy demand and UTILIZATION OF VESIDUAL HEAT IN in production technology.The present embodiment is in a circulatory system, to be connected in parallel to heat exchanger 6 for bathing, heating heat exchanger 7 and air-heater 8, the cold water that enters heat transmission equipment is heated, after heat exchange, produce high-temperature-hot-water, then be transported in heating and bath system, to substitute coal-burning boiler heating system by circulating pump.High-temperature-hot-water is transported to heater by circulating pump in addition, produces hot blast blow to coal mine by warm-air drier.Flue gas after heat exchange is transported to former air supply duct, uses for dry kiln dry brick.Strengthen the Insulation of the air inducing flue of calcining kiln, on the thermal insulation foundation of original air inducing pipeline, increase insulation layer thickness, heat loss rate is reduced within 15%, can farthest meet heat energy demand and UTILIZATION OF VESIDUAL HEAT IN in production technology.
The waste heat transmittance process of fume side is: the heat of fume side, by internal softening water under the dynamic action of water circulating pump 9, demineralized water flows through heat exchanger 6, heat exchanger 7 and air-heater 8, absorb the heat of high-temperature flue gas, transfer heat to outside cold water (or air), then demineralized water absorbs heat entering flue gas heat-exchange unit 2 by water circulating pump 9, so circular flow.
