Open type earth's surface water source heat pump water-fetching water treatment system

Abstract

The invention provides an open ground surface water source heat pump water intaking water treatment system, comprising a water intaking system and a filtering system connected in series with the water intaking system; wherein the water intaking system consists of a water intaking head A, the water intaking head B, a water intaking pump a, a water intaking pump b, pipelines and valves; the pipelines of the water intaking head A and the water intaking head B are arranged and connected in parallel; the filtering system is formed by at least two filtering pipelines connected in parallel; and the output end of the filtering system is connected with a heat pump set Z. The system can not only efficiently avoid the blockage of the water intaking head by floating materials, but also efficiently remove sand and algae, thus preventing the floating materials, mud, sand, and the like from blocking and eroding a channel of the heat pump system and preventing the algae and the like from forming biologicalfouling on the pipe wall of the heat pump system. The back washing of the water intaking head of the system is controlled by a valve arranged on a pipeline connecting the water intaking head and a water intaking pump, thus no additional back washing system is necessary; and the back washing of a filter does not need the additional back washing system and can be achieved while the back washing of the filter is controlled by the inlet and outlet valves of the filter. The system can not only save the power consumed by the drainage of the sand and the mud with water, save infrastructure and operation expenses; but also greatly reduce the drainage, erosion and scale formation of the pipeline of the heat pump system and improves the heat exchange efficiency of the open ground surface water source heat pump system.

Description

technical field [0001] The invention relates to the field of water supply engineering, in particular to an open surface water source heat pump intake water treatment system that prevents sediment clogging and has efficient algae removal functions. Background technique [0002] The water source heat pump system has been widely researched and applied in the field of engineering technology because of its advantages of high efficiency, energy saving and environmental protection due to the use of renewable energy. The open surface water source heat pump system in the water source heat pump system directly introduces the water source into the unit or the intermediate heat exchanger for heat exchange, which must have strict requirements on the water quality of the water source. Therefore, the open surface water source heat pump must treat the raw water quality. At present, there are three main types of water treatment processes for open surface water source heat pump intake: [0...

Problems solved by technology

However, the construction of this process is complicated, and the initial investment is relatively large; and the use of the process is strictly limited by engineering geology and hydrogeology; in the later stage of infiltration canal water intake, the water intake effect is often easily affected due to pipeline blockage, and the service life is difficult to guarantee
