Problems solved by technology

[0003] At present, only the driver’s cabin has the ability to adjust the temperature on the current mobile vehicle. If additional occasions (some special vehicles) need to adjust the temperature and relative humidity, an additional air conditioning unit is required, resulting in an increase in the demand for additional energy and increasing the vehicle’s energy consumption. Fuel consumption reduces the cruising range of the vehicle

Embodiment 1

[0032] This embodiment is a refrigeration working principle of a waste heat recovery air treatment device: hot circulating water flows through the three-way valve I7 and the three-way valve II8, and enters the absorption refrigerator. At this time, the three-way valve I7 and the three-way valve II8 are both A Connect to port B and close port C; use hot circulating water as a heat source to make absorption refrigerator 12 generate cooling capacity, which is brought to the air handler 10 by the cooling water driven by circulating water pump II13 to cool the air, and the cooling water itself After being heated up, it returns to the absorption refrigerator 12, and the condensation heat is taken to the air-cooled heat exchanger 9 by the cooling water driven by the circulating water pump III14, released to the ambient heat sink, and then returned to the absorption refrigerator 12. By adjusting the rotating speed of the circulating water pump II12, the cooling water flow can be adjust...

Embodiment 2

[0034] This embodiment is a heating working principle of a waste heat recovery air treatment device: hot circulating water flows through the three-way valve I7 and enters the air heat exchanger to heat the heat exchanger. At this time, the A and C ports of the three-way valve I7 are connected, and the B port Closed; the hot circulating water directly enters the air handler 10 to heat the heat exchanger, heats the air flowing through the heat exchanger to achieve heating, and adjusts the heating capacity and heating temperature by adjusting the flow and temperature of the hot circulating water.

Embodiment 3

[0036] This embodiment is a dehumidification working principle of waste heat recovery air treatment device. The hot circulating water enters from the A port in the three-way valve I7, and the B port and the C port are both opened, and the hot circulating water passing through the C port is used to dehumidify the air. Heating, the hot circulating water from port B enters through the port A of the three-way valve Ⅱ8, and exits from the port B into the absorption refrigerator 12 as a heat source. By adjusting the speed of the circulating water pump Ⅱ13 to adjust the flow rate, thereby adjusting the flow into the cooling heat exchanger Cooling water temperature, so that the temperature is lower than the dew point temperature of the circulating air to realize the dehumidification function. At the same time, the circulating water pump III14 drives the cooling water to flow between the absorption refrigerator 12 and the air-cooled heat exchanger 9, and takes away the moisture in the ab...

Abstract

The invention discloses a waste heat recovery air treatment device, which relates to the field of environmental protection and energy saving. In the present invention: the circulating water in the circulating water tank is transported to the waste heat recovery device through the circulating water pump I; the waste heat recovery device is connected to the A port of the three-way valve I; the B port of the three-way valve I is connected to the A port of the three-way valve II; Port C of the three-way valve Ⅰ is connected to the circulating water tank through the air handler; port B of the three-way valve Ⅱ is connected to the circulating water tank through the absorption refrigerator; the absorption refrigerator is also connected to the air-cooled heat exchanger through the circulation pipeline and the circulating water pump III Connection; port C of the three-way valve II is connected to the circulating water tank through a humidifier. The invention uses a liquid circulation system composed of a circulating water pump, a waste heat recovery device, an air-cooled heat exchanger, an air processor, a steam generator and an absorption refrigerator to adjust the air temperature and relative humidity in a closed space; utilize the waste heat of the engine As an energy input, there is no need to increase energy consumption, and the overall fuel utilization efficiency of the vehicle is improved.

Description

technical field [0001] The invention belongs to the technical field of environmental protection and energy saving, and in particular relates to an air treatment device for waste heat recovery. Background technique [0002] At present, the main power source of mobile vehicles is a fuel engine, and the effective thermal efficiency of a fuel engine is relatively low. For example, the effective thermal efficiency of a gasoline engine is generally 20% to 35%, and the effective thermal efficiency of a diesel engine is generally 35% to 45%. A lot of waste heat is generated during work. At the same time, in order to improve the comfort of personnel or the reliability of equipment and instruments, electric drive air-conditioning units and humidification units are usually used to adjust the temperature and relative humidity of the ambient air where personnel or equipment and instruments are located, which increases the load on the power supply system. Therefore, using the waste heat ...
