Problems solved by technology

Furthermore, if impurities in the water source are introduced into the heat exchanger, it will block it, resulting in a decrease in heat exchange capacity, and cleaning the heat exchanger for a long time will damage the internal heat exchange tubes
If the cold and heat sources are rivers, rivers, lakes, groundwater, and underground buried pipes, it will cause uneven cold and heat in the surrounding environment during use.
For example, after heat exchange with lake water, the ambient temperature in the lake will be affected. In summer, the temperature of lake water will increase and in winter, the temperature will decrease. The organisms living in the interior may not adapt to the change of environmental temperature and die; after heat exchange with groundwater and underground soil , also lead to changes in underground temperature, so that the surrounding plants do not adapt to their ambient temperature and die

Embodiment Construction

[0031] First, see figure 1 As shown, a sewage source heat pump central air conditioning system provided by the present invention includes a water source heat pump central air conditioning system. The water source heat pump central air conditioning system is mainly composed of a water source heat pump unit A and a heat exchange terminal B cyclically connected, in order to prevent The circulating cold medium in the water source heat pump central air conditioning system cannot work normally due to constant loss. The return path of the heat exchange terminal B connected to the water source heat pump unit A is also provided with a water supplement C and a water tank D. In this way, the water source heat pump unit A, the heat exchange terminal B, the water supplement device C, and the water supplement tank D are connected end to end to form a circulation loop; and the characteristics of the present invention are:

Abstract

The invention provides a sewage treatment device. A shell is vertically divided into a filter cavity and a scouring cavity, two sides of the filter cavity are provided with a sewage inlet and a filtered water outlet, two sides of the scouring cavity are provided with a water return port and a blow-off port, and the sewage inlet and the filtered water outlet are separated by using a filter screen; and a bowl sleeve is fixed on the inner wall of the shell, a piston rod passes through the center of the bottom of the bowl sleeve, the upper end of the piston rod extends into the filter cavity and reciprocates up and down to drive bristles of a plurality of rotor plates to clean the filter screen, the lower end of the piston rod is in power connection with a hydraulic cylinder fixed below the shell, the rod body of the piston rod is also provided with a ring slot, and the upper and lower stroke limit positions of the ring slot are positioned in the precipitation cavity and the scouring cavity respectively. The invention also provides a sewage source heat pump central air-conditioning system which is connected with the sewage treatment device. The device treats sewage, provides refrigerating and heating effects by using sewage, and is environment-friendly.

Description

Technical field [0001] The invention relates to a device for treating sewage, and also to a water source heat pump central air conditioning system. Background technique [0002] At present, the heat pump central air conditioning system is basically divided into: water source (river, river, lake, groundwater) heat pump central air conditioning system and ground source heat pump central air conditioning system. [0003] This kind of heat pump central air-conditioning system uses the existing water source to exchange heat with the unit or the buried pipe buried deep underground to exchange heat with the unit through the intermediate water. Because of the heat exchanger installed in the front, it will greatly reduce the heat exchange efficiency and cause energy loss. Furthermore, if impurities in the water source are introduced into the heat exchanger, it will block it, resulting in a decrease in heat exchange capacity, and cleaning the heat exchanger for a long time will damage the i...
