Embodiment 1

[0020] A heating system integrating multiple waste heat couplings, including a float glass waste heat recovery device, a solar waste heat recovery device and a lithium bromide heat pump heating device.

[0021] The float glass waste heat recovery device includes a float glass workshop (1), a hot pool (22), a cold pool (21), a second circulation pump (17), a third circulation pump (18) and two-stage control valves, The cooling tower (6), the heat pump, the first water outlet of the float glass workshop (1) is led into the heat pool (22) by the first water pipe, the inlet of the cooling tower (6) is connected to the upper water pipe, and the outlet of the cooling tower (6) The pipeline leads to the cold pool (21), the upper water pipe is equipped with a two-stage control valve and a circulating pump, the upper water pipe leads to the hot pool (22), and the circulating pump is arranged between the hot pool (22) of the upper water pipe and the two-stage control valve At the positi...

Embodiment 2

[0054] A power plant waste heat, solar energy, and float glass waste heat coupling heating system. The whole system is composed of a float glass waste heat recovery device, a solar waste heat recovery device, and a lithium bromide heat pump heating device.

[0055] The main working principle of the float glass waste heat recovery device is: when the waste heat recovery is carried out in winter, the 37-39 ℃ circulating water containing a large amount of low-temperature waste heat generated by the float glass workshop 1 is discharged into the heat pool 22, and the third circulating pump 18. Pressurize the second circulation pump 17, open the eighth control valve 12, the ninth control valve 13, the tenth control valve 14, the eleventh control valve 15, and close the third control valve 7 and the fourth control valve 8 , the fifth control valve 9, the sixth control valve 10; these circulating water are introduced into the first heat pump 23, the second heat pump 24, and the third h...

Abstract

The invention discloses a water mixing and water distributing type energy-saving, heating and water supplying method, and belongs to the field of heating waste heat recovery and heat distribution. Inorder to solve the problems that float glass waste heat and solar waste heat serve as heating sources, and medium water which is subjected to heat exchange and has relatively stable low temperature isused for a heat pump unit, the medium water is cooled by a cooling tower (6) and then is discharged into a cold pool (21), circulating water of the cold pool (21) is pressurized by a first circulating pump (5), a second control valve (4) is opened, the circulating water of the cold pool (21) is conveyed to a float glass workshop (1) to serve as float glass production cooling water, and excessiveheat energy is stored by a phase change heat storage device (31) through a pipeline provided with the phase change heat storage device (31). The method has the effect that the medium water for float glass waste heat recovery is reheated by a solar waste heat recovery device.

Description

technical field [0001] The invention belongs to the field of heating waste heat recovery and heat distribution, and relates to a water mixing and water dividing method for energy saving, heating and water supply. Background technique [0002] In recent years, with the increase of urban heating area in my country and the increase of production line construction in industrial plants, the heat consumption in my country has increased rapidly. From the analysis of heating methods, there are currently the following ways for residents to heat in my country: thermoelectricity Combined production mode, central heating of small and medium-sized regional boiler rooms, small domestic gas water heaters, household coal-fired furnaces, etc., among which the combined heat and power mode is a combination of using the high-grade thermal energy of the fuel to generate electricity and then using its low-grade thermal energy for heating Use energy technology. At present, the average power generat...
