Embodiment 1

[0014] 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.

[0015] 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

[0048] 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.

[0049] 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 distribution type energy-saving, heating and water supply system, belongs to the field of heat supply waste heat recovery and heat distribution, and aims to achieve the effects that floating-method glass waste heat and solar energy waste heat are used as heat supply heat sources, and medium water being relatively stable and being in low temperatureafter heat exchange is used for a heat pump unit. The system is characterized in that branch water pipes are connected with heat pumps through a pipeline, a seventh control valve (11) is arranged on the pipeline used for connecting the branch water pipes to the heat pumps, the number of the heat pump is three, a water outlet pipe of a solar water heater (34) is branched into two water pipes connected in parallel, a thirteenth control valve (32) is arranged on one water pipe, an outlet of the water storage tank (37) communicates with a water mixer (42), an outlet of the water mixer (42) is connected with an inlet of a low-temperature heat exchange section, an outlet of the low-temperature heat exchange section is connected with a second water distributor (44), and the second water distributor (44) is provided with a two-way water dividing valve (43). The system has the effect that medium water recovered through floating-method glass waste heat is reheated by a solar waste heat recoverydevice.

Description

technical field [0001] The invention belongs to the field of heating waste heat recovery and heat distribution, and relates to an energy-saving, heating and water supply system of water mixing and water dividing type. 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 ge...
