The specific implementation mode is as follows:
the invention is further described with reference to the accompanying drawings in which:
as shown in fig. 2, the waste heat heating system provided by the invention mainly comprises a heat exchanger 7, a afterburning boiler 8, an air processor 9, an air-conditioning circulating pump 13, a cold water tank 10, a hot water tank 11, an expansion tank 12, a matching pipeline and the like. The heating operation principle is shown in fig. 2, and comprises two parts of a heating wind function and a heating water function. The heating wind function is used for providing warm wind for the user in severe cold weather; the water heating function is used for providing sanitary hot water with proper temperature for a user to meet the requirements of showering or living.
The heat exchanger 7 is a sleeve fin type finned tube heat exchanger, and is manufactured by tightly sleeving a stamped fin on the wall of a metal tube. The heat transfer performance of the finned tube is higher because the heat transfer performance of the finned tube is related to the thermal contact resistance between the fin and the base tube, and the thermal contact resistance depends on the contact pressure between the fin and the base tube. On the premise of ensuring the heat exchange quantity, the volume and the weight are greatly reduced. The finned tube heat exchanger of the set of slice type includes the inlet port 1, tobacco juice heat transfer area 2 and outlet port 3 connected sequentially; wherein, a liquid outlet 4, a liquid return port and a temperature sensor 6 for measuring the temperature of the liquid in the pipeline are arranged on the tobacco liquid heat exchange area 2.
The afterburning boiler 8 integrates heat exchange and afterburning functions. The functions are as follows: when the system residual heat is surplus, the system residual heat is used as a secondary heat exchanger, and the residual heat is transferred to the hot water tank 11 to be stored in hot water; when the residual heat of the system is insufficient, the supplementary heat is started to supply heat or the system is independently operated to supply hot water.
Function of the air handler 9: and outputting hot wind to a user when the hot wind is generated.
Function of the air-conditioning circulation pump 13: the heating medium in the air conditioning pipeline is driven to circularly flow in the air processor 9, the heat exchanger 7 and the afterburning boiler 8.
The cold water tank 10 functions as: 1) supplying water to the hot water tank 11; 2) when the shower is in operation, the hot water and the hot water in the hot water tank 11 are mixed together through the water mixing valve and then are supplied outwards.
The function of the hot water tank 11 is: the hot water exchanged by the waste heat or the work of the after-burning boiler 8 is stored, and when the water is needed, the hot water and the cold water in the cold water tank 10 are mixed together by the water mixing valve and then are supplied outwards. When the residual heat is surplus, the system can be used as a heat storage device of the system. The water supplement of the cold water tank 10 is provided by an extravehicular soft water tank.
The function of the expansion vessel 12 is: provides a stable constant pressure point for the air-conditioning circulation loop and provides the functions of expansion and pressure relief for the afterburning boiler 8.
In addition, the present invention further includes a showerhead 18 in communication with both the hot water tank 11 and the cold water tank 10, wherein the cold water tank 10 is used to regulate the hot water temperature of the showerhead 18. A hot water booster pump 16 is arranged on a pipeline which is communicated with the shower nozzle 18 and the hot water tank 11; the pipeline of the shower nozzle 18 communicated with the cold water tank 10 is provided with a cold water booster pump 17.
For a further understanding of the present invention, the working process thereof will now be described as follows:
1. heating wind
In winter conditions, the user starts a hot air making mode. The high-heat flue gas flows through the heat exchanger 7, under the drive of the air-conditioning circulating pump 13, the antifreeze in the air-conditioning circulating pipeline exchanges heat with the flue gas to obtain higher temperature, then flows through the afterburning boiler 8 and the air processor, is converted into hot air in the air processor through heat exchange, and is conveyed to a use space through the air processor fan to realize heating. When the waste heat is insufficient, the after-burning boiler 8 is automatically started, and heat is supplemented to heat the antifreeze in the air-conditioning circulation pipeline so as to meet the heating requirement.
2. Water heating device
When a user starts the hot water heating mode, the hot water heating function can be realized. The principle of heating water is divided into two cases: 1) when the stop valve 17 in fig. 2 is in a closed state, the sanitary cold water in the hot water tank 11 and the antifreeze solution perform secondary heat exchange in the afterburning boiler 8 under the driving of the hot water circulating pump 14 to obtain sanitary hot water with higher temperature; 2) when the stop valve 17 in fig. 2 is in an open state, the afterburning boiler 8 is started alone, and the hot water circulating pump 14 drives the sanitary cold water in the hot water tank 11 to be heated directly by the afterburning boiler 8, so as to obtain sanitary hot water with high temperature.
