Electric drive heat pump unit with smoke comprehensive treatment function

Abstract

The invention discloses an electric drive heat pump unit with a smoke comprehensive treatment function. The electric drive heat pump unit comprises a refrigerant circulation loop formed by a compressor, a condenser, a throttle valve and an evaporator, the water side of the condenser and the water side of the evaporator are connected with a user air-conditioning system, the water side of the evaporator and the water side of a smoke-water heat exchanger are connected to form a circulated water waste heat recovering loop, a first electric two-way valve and a circulation pump are arranged on the water side of the evaporator, a second electric two-way valve is arranged on a water return main pipe of the user air-conditioning system, a smoke side inlet of the smoke-water heat exchanger is connected with an outlet of a chimney of a boiler, a smoke side outlet of the smoke-water heat exchanger is connected with an air inlet of an air-liquid separator, an exhaust opening is formed in the top ofthe air-liquid separator, a water discharging opening is formed in the bottom of the air-liquid separator, an agent adding opening is formed in the side portion, and an agent adding device is connected to the agent adding opening. By means of the electric drive heat pump unit, waste heat in smoke can be recovered, and contaminant in the smoke is treated.

Description

technical field [0001] The invention relates to an electrically driven heat pump unit, in particular to an electrically driven heat pump unit with comprehensive flue gas treatment functions. Background technique [0002] The flue gas components emitted by gas-fired boilers mainly include water vapor, carbon dioxide and a very small amount of nitrogen oxides and sulfur dioxide. The following problems exist in the flue gas emission process: [0003] (1) There is a large amount of low-grade heat energy contained in the flue gas, and this part of heat energy is not recovered and directly discharged, resulting in serious energy waste. [0004] (2) The "white smoke" phenomenon caused by water vapor has certain visual pollution, which affects the image of surrounding urban areas. [0005] (3) Sulfur dioxide and nitrogen oxides are one of the main causes of air pollution, affecting the living environment of surrounding residents. [0006] The main reason for the current situation ...

AI Technical Summary

Problems solved by technology

[0003] (1) There is a large amount of low-grade heat energy in the flue gas, and the heat energy is not recovered and discharged directly, resulting in serious energy waste

[0004] (2) The "white smoke" phenomenon caused by water vapor has certain visual pollution, which affects the image of surrounding urban areas

[0006] The main reason for the current situation is that the recovery of flue gas waste heat and the treatment of pollutants in the flue gas were not considered at the beginning of the design of the gas boiler. In order to eliminate the existing disadvantages, a better system solution needs to be proposed
