Mixed classification heat replenishment combined method for heat pump heat supply and float glass waste heat recovery

Abstract

The invention discloses a mixed classification heat replenishment combined method for heat pump heat supply and float glass waste heat recovery, and belongs to the field of heat supply waste heat recovery and heat distribution. The combined method aims to enable circulating water to participate in secondary heat exchange. Other water is conveyed to a water return heat replenishment device by a low-temperature heat exchange water pipe to serve as return water, a first temperature sensor of the water return heat replenishment device detects the temperature of the return water, and stored water in a water storage tank is started to be used when the detected temperature is lower than a set threshold value of 24 DEG C; in the water return heat replenishment device, heat exchange is carried outbetween stored water in a high-temperature heat exchange water pipe and the return water in the low-temperature heat exchange water pipe, so that the temperature of the return water is increased, andthe temperature of the return water can be stabilized at the set threshold value; and pressurization is carried out on a second circulating pump and a third circulating pump, after the pressurizationis completed, an eighth control valve, a ninth control valve, a tenth control valve and an eleventh control valve are opened, and the effect that the water return heat replenishment device provides medium water for a float glass waste heat recovery device to form circulating water utilization.

Description

technical field [0001] The invention belongs to the field of heating waste heat recovery and heat distribution, and relates to a combined method of heat pump heating with mixed heat supply and float glass waste heat recovery. 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 ...

Problems solved by technology

However, the low-temperature industrial waste heat represented by the float glass factory is currently being discarded for nothing, or it is discharged using additional hydropower resources. It is a pity to discard it.
