Energy-saving type absorption heat pump allowing waste water to flow into evaporator directly

Abstract

The invention discloses an energy-saving type absorption heat pump allowing waste water to flow into an evaporator directly, and belongs to an energy-saving type absorption heat pump used for recycling waste heat of waste water sources. The energy-saving type absorption heat pump allowing waste water to flow into the evaporator directly comprises an absorption heat pump body formed by a generator, a condenser, an absorber and the evaporator. A high-temperature heating medium inlet pipe and a high-temperature heating medium outlet pipe are connected to the generator, a heating water return pipe is connected to an absorber inlet, and a heating water outlet pipe is connected to a condenser outlet. The energy-saving type absorption heat pump allowing waste water to flow into the evaporator directly is characterized in that a waste water inlet pipe and a waste water outlet pipe are directly connected to the two ends of a heat exchange pipe bundle of the evaporator of the heat pump and are connected with a rubber ball cleaning device in parallel. Since waste water flows into the evaporator directly for heat release, the rubber ball cleaning device is adopted to clean the pipe bundle on the waste water side of the evaporator regularly, the pipe bundle can maintain high-efficiency heat exchange, intermediate heat exchange equipment for heating and heat exchanging is omitted, system investment and power consumption of a water pump are reduced, heat exchange temperature losses are eliminated, and new equipment is provided for utilization of waste water and waste heat.

Description

Technical field [0001] The invention belongs to an energy-saving absorption heat pump for recovering waste heat from sewage sources. Used to recover waste heat from sewage, which directly enters the evaporator of the absorption heat pump. Background technique [0002] In order to recover the waste heat carried in high-temperature sewage, sewage source absorption heat pumps are used in many places to recover waste heat for heating hot water. However, traditional sewage source absorption heat pumps generally use sewage due to the problems of corrosion, clogging, and wear in sewage. The heat exchanger first exchanges heat between sewage and clean water, and then sends the clean water to the evaporator to extract heat using absorption heat pump technology. Realize the recovery and utilization of waste heat from sewage sources and realize energy-saving benefits. This method requires facilities such as sewage heat exchangers and clean water circulation pumps to recover waste heat from...

Problems solved by technology

[0003] In order to overcome the existing waste heat recycling method of using sewage heat exchangers to exchange heat between sewage and clean water, and then send clean water to the evaporator and use absorption heat pump technology to extract heat from sewage sources, there are many equipments used and high heat. The invention provides an energy-saving absorption heat pump in which the sewage directly enters the evaporator. The energy-saving absorption heat pump in which the sewage directly enters the evaporator not only saves the sewage heat exchanger used for heat exchange between sewage and clean water, And it can well solve the problem that the evaporator is prone to dirt after the sewage directly enters the evaporator
