Abstract

The invention discloses a high-temperature vapor heat pump system for generating vapor by utilizing low-grade waste heat, which comprises a heat pump circulating device and a water vapor generation circulating device, wherein the heat pump system recycles the industrial waste heat (20-40 DEG C) and exhausts the heat in a condenser; water on the other side absorbs the heat to be evaporated into the 80 DEG C water vapor; the heat is absorbed by a heat regenerator and becomes overheated vapor under the negative pressure; the overheated vapor is supplied to industrial production through the pressurization of a water vapor compressor, thereby recycling the industrial waste heat and solving the problem that a common heat pump cannot generate vapor below 100 DEG C, which is an innovative system form. The invention has the innovation points that the heat pump system with excellent energy saving performance is combined with the water vapor generation circulation; and the water vapor is generated under the negative pressure, and the waste heat is fully utilized and recycled and the problems which cannot be overcome by the common heat pump are solved.

Description

technical field [0001] The invention relates to a high-temperature steam heat pump system device that utilizes low-grade waste heat to generate steam, in particular to a high-temperature steam heat pump system that utilizes industrial waste heat (20°C to 40°C) to generate steam. Background technique [0002] Waste heat is energy that has not been used in energy utilization equipment under certain economic and technical conditions, that is, excess and waste energy. It includes waste heat of high-temperature exhaust gas, waste heat of cooling medium, waste heat of waste steam and wastewater, waste heat of high-temperature products and slag, waste heat of chemical reaction, waste heat of combustible waste gas and waste liquid and waste, and excess pressure of high-pressure fluid. According to the survey, the total waste heat resources of various industries account for about 17%-67% of their total fuel consumption, and the recyclable waste heat resources are about 60% of the tot...
