Abstract
A boiler off-gas waste-heat recycling device is used for a boiler which is arranged on a vent of the high-temperature off-gas. The boiler off-gas waste-heat recycling device comprises a water softener, a water-cooling tank, a heat-exchanger, a hot water tank and a deoxidizing device which are connected with each other through water pipes in order. One end of the heat exchanger is communicated with the vent of the boiler and the high-temperature off-gas is emitted to the atmosphere through the vent and the heat exchanger. The cold water from the water softener flows into the water-cooling tank and then the water from the water-cooling tank flows into the heat exchanger, and through the heat exchanging between the cold water and the high-temperature gas the water from the water-cooling tank is heated into hot water which flows into the hot water tank, then through the deoxidizing device and pipes the water from the hot water tank flows into the boiler for recycling.
Description
Technical field
The utility model relates to a kind of residual heat from boiler fume use device, and 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 purpose of this utility model is to provide a kind of residual heat from boiler fume use device, and it saves boiler oil, reduces production costs.
For achieving the above object, the utility model 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, 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.
The utlity model 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 the utility model residual heat from boiler fume use device.
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.
Connect a water pipe 52 between this cold water storage cistern 3 and this boiler 5, water can be directly enters in the boiler 1 by water pipe from oxygen-eliminating device 6 backs of flowing through after cold water storage cistern 3 flows into boilers 5 and uses.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.
In the utility model, 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, 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.
More than be first embodiment of the present utility model, in a second embodiment, on the water pipe 30 between this cold water storage cistern 3 and the heat exchanger 4, one circulating pump can only be installed, this circulating pump pumps into heat exchanger 4 with the cold water of 3 li of cold water storage cisterns, on the water pipe 30 between this cold water storage cistern 3 and the heat exchanger 4, a valve is installed only, omit circulating pump and the valve installed as on described branching pipe 33 of first embodiment and the branching pipe 33, can solve the technical problems to be solved in the utility model equally.
