Abstract
The invention relates to a boiler flue gas waste-heat utilization device that includes a water softener, cooling water box, heat exchanger, a hot water tank, and a deaerator, which are connected through water pipe. One end of the heat exchanger connects to the exhaust port of the boiler. And high temperature flue gas would be exhausted port into air through exhaust port and heat exchanger. The cold water from water softener would flow into cold water tank. And the cold water from cold water tank would take exchange. And the hot water from hot water tank would be used in boiler after flowing from deaerator.
Description
Technical field
The present invention relates to a kind of residual heat from boiler fume use device, high-temperature flue gas and cold water heat exchange that this device utilizes boiler to discharge produce hot water, offer boiler and use.
Background technology
Boiler is the heat energy that utilizes fuel or other energy, working medium (being generally the water of evolution) is heated to the heat transmission equipment of certain parameter (temperature, pressure).The task of boiler is safety, reliably, the chemical energy with fuel is converted into heat energy cost-effectively, and then with the thermal energy transfer feedwater, to produce hot water or steam; Or the chemical energy of fuel passed to other working medium, as the heat conduction wet goods, to produce the working medium of other high temperature, as high temperature heat conductive oil.Boiler will give off the flue gas of high temperature, directly is discharged in the atmosphere and is not used, and is very unfortunate.
Summary of the invention
The object of the present invention is to provide a kind of residual heat from boiler fume use device, it saves boiler oil, reduces production costs.
For achieving the above object, the invention provides a kind of residual heat from boiler fume use device, it is used in a boiler, the exhaust outlet of this boiler erection one discharging high-temperature flue gas, and this residual heat from boiler fume use device comprises a water softener, a cold water storage cistern, a heat exchanger, a boiler, an oxygen-eliminating device; Water pipe connection successively between this water softener, cold water storage cistern, heat exchanger, boiler, the oxygen-eliminating device; This heat exchanger one end is communicated with the exhaust outlet of this boiler, high-temperature flue gas is discharged in the atmosphere by exhaust outlet and heat exchanger, the cold water that water softener flows out flows to cold water storage cistern, and the cold water that cold water storage cistern flows out enters heat exchanger, and cold water flows to boiler through being heated into hot water with the high-temperature flue gas heat exchange; The flow of hot water that boiler flows out enters in the boiler by water pipe behind oxygen-eliminating device and uses.
The present invention has following beneficial effect: in heat exchanger, the cold water of heat exchanger of flowing through carries out heat exchange and is heated as hot water through the high-temperature flue gas of discharging with boiler, feed in the boiler then and use, because what feed is the higher hot water of temperature, therefore save the fuel of boiler, reduced production cost.
Description of drawings
Fig. 1 is the structural representation of residual heat from boiler fume use device of the present invention.
The specific embodiment
See also Fig. 1, a kind of residual heat from boiler fume use device, it is used in a boiler 1, and this boiler 1 comprises the exhaust outlet 12 of a discharging high-temperature flue gas.This residual heat from boiler fume use device comprises a water softener 2, a cold water storage cistern 3, a heat exchanger 4, a boiler 5, an oxygen-eliminating device 6.
Water pipe connection successively between this water softener 2, cold water storage cistern 3, heat exchanger 4, boiler 5, the oxygen-eliminating device 6.
One first valve 31, one first circulating pump 32 and one second valve 34 are installed on the water pipe 30 between this cold water storage cistern 3 and the heat exchanger 4 successively.One branching pipe 33 also has been installed between this cold water storage cistern 3 and the heat exchanger 4, one the 3rd valve 35, one second circulating pump 36 and one the 4th valve 38 are installed on it, they are standby as first valve 31, first circulating pump 32 and one second valve 34, when first valve 31, first circulating pump 32 and second valve 34 break down, can use the 3rd valve 35, second circulating pump 36 and the 4th valve 38.This first circulating pump 32 or second circulating pump 36 can pump into heat exchanger 4 with the cold water of 3 li of cold water storage cisterns.
These heat exchanger 4 one ends are communicated with the exhaust outlet 12 of this boiler 1, and the other end is communicated to a chimney 7, and the high-temperature flue gas of boiler is discharged by heat exchanger 4 from exhaust outlet 12, is discharged in the atmosphere through chimney 7 then.The cold water that flows out from water softener 2 flows to cold water storage cistern 3, and the cold water that cold water storage cistern 3 flows out enters heat exchanger 4, and cold water and high-temperature flue gas heat exchange in heat exchanger 4 and be heated to form hot water flow to boiler 5 afterwards; The flow of hot water that boiler 5 flows out is sent use in the boiler 1 to by water pipe behind oxygen-eliminating device 6.Because what feed is the higher hot water of temperature, therefore saved the fuel of boiler, reduced production cost.
Also be connected with a water pipe 52 between this cold water storage cistern 3 and this boiler 5, one the 5th valve 54, one the 3rd circulating pump 56, one the 6th valve 58 are installed on the water pipe 52 between this cold water storage cistern 3 and this boiler 5 in order.By the 3rd circulating pump 56, cold water can be pumped in this boiler 5.
Among the present invention, in heat exchanger 4, the cold water of heat exchanger 4 of flowing through carries out heat exchange and is heated as hot water through the high-temperature flue gas of discharging with boiler 1 row 1, feed then in the boiler 1 and use, because what feed is the higher hot water of temperature, therefore save the fuel of boiler, reduced production cost.
