Heat pump type steam generator

Abstract

The invention relates to a heat pump steam generator. Air source heating pump comprises compressor, primary end of energy coupling heat exchanger, expansion valve and air heat exchanger. Heating pump for high-temperature water of artificial source supplied by the air source heating pump comprises compressor, high-temperature water heat exchanger with electric heater, warm-water exchanger, expansion valve and secondary end of energy coupling heat exchanger. Heating pump for high-temperature water of air source comprises compressor, high-temperature water exchanger, warm-water exchanger, expansion valve and air exchanger through allocation valve. The invention makes use of the heating pump of air source to obtaining heat quantity in air and provides an artificial heating source for the heating pump for high-temperature water of artificial source so that it is realized that steam is heated in high efficiency. And steam can be generated by high-temperature exchanger with electric heater. Because 90% or so of total heat energy for generating steam is provided by the heating pump and only 10% or so for steam is provided with the electric heater, energy consumption for steam can be decreased greatly and working efficiency of steam generator can be improved.

Description

technical field [0001] The invention relates to a steam generator, in particular to a heat pump type steam generator. Background technique [0002] Many processes and productions require the use of steam. At present, coal, gas, oil and electric heating are the main ways to obtain steam. The steam production efficiency of the equipment is low, the energy consumption is high, and the coal-fired steam production method will also generate a large amount of energy. Exhaust gas and dust, causing environmental pollution. Contents of the invention [0003] The purpose of the present invention is to solve the above problems and provide a heat pump steam generator with high steam production efficiency, low energy consumption and no environmental pollution. [0004] The technical solution to achieve the above purpose is: a heat pump steam generator, which is composed of a refrigerant pipeline connected to a compressor, a valve, a primary end of an energy coupling heat exchanger, an ...
