Multi-tank adsorption type sewage source heat pump

Abstract

The invention discloses a multi-tank adsorption type sewage source heat pump. The multi-tank adsorption type sewage source heat pump comprises an adsorption type heat pump system, a sewage circulatingsystem, a cooling water circulating system and a hot water heating system. A desorption generator is heated by heated sewage, ammonia gas is desorbed, the ammonia gas is condensed into liquid ammoniathrough a condenser to enter a liquid ammonia storage tank, then the liquid ammonia enters an evaporator through throttling and pressure reduction of a throttling valve, the heated sewage is heated to become a gas state, the gas state enters an adsorption generator through control of an electromagnetic valve, the gas state is adsorbed by a calcium chloride composite adsorbent on an internal adsorption bed, adsorption heat is released, the adsorption heat heats hot water in a heat exchanger, the temperature of the hot water is increased, and the heating process is completed. An adsorption generator set comprises a plurality of adsorption generators, and the proportion of the adsorption generators to the desorption generator is determined on the basis of an adsorption-desorption theoreticalcalculation model. According to the adsorption generator set, three or more adsorption generators are adopted, so that adsorption and desorption are more balanced, the unit efficiency is improved, and operation is more stable.

Description

technical field [0001] The invention relates to the technical field of sewage source heat pumps, in particular to a multi-tank adsorption sewage source heat pump. Background technique [0002] Energy and the environment are the two major themes of sustainable development. At present, building heating based on burning petrochemical raw materials not only consumes a lot of energy, but also causes great pollution to the environment. Urban sewage is composed of industrial wastewater and domestic sewage. The water volume is huge. It is a renewable heat energy resource rich in low-level heat energy. The sewage source heat pump system uses urban sewage as the cold and heat source of buildings to solve the problem of building heating in winter and summer. An important technology for air conditioning and year-round hot water supply is also an idea and an effective way to develop and utilize urban sewage resources, while reducing urban waste heat and emissions of pollutants such as CO...
