Ice water filtering device for ice source heat pump system

Abstract

The invention belongs to the technical field of ice water filtering, and particularly relates to an ice water filtering device for an ice source heat pump system. The device comprises a rotary filtering cylinder, an ice slurry inlet is formed in one side of the upper portion of the rotary filtering cylinder, and a rotating shaft is connected to the center of the upper portion of the rotary filtering cylinder. The four walls of the rotary filtering cylinder comprise mesh structures, and the mesh structures are used for filtering and separating ice crystals and water in the ice slurry. The ice water filtering device further comprises a water containing cavity formed in the outer portion of the rotary filtering cylinder, and the water containing cavity is used for receiving water separated from the mesh structures on the four walls of the rotary filtering cylinder in the rotating process of the rotary filtering cylinder. A water outlet is formed in one side of the bottom of the water containing cavity. Rapid and efficient separation of ice crystals and water in ice slurry of the ice source heat pump system is achieved through the filtering effect of the mesh structures and the centrifugal force of the rotary cylinder.

Description

technical field [0001] The invention belongs to the technical field of ice water filtration, and more particularly relates to an ice water filter device used in an ice source heat pump system. Background technique [0002] In recent years, my country has actively developed water-source heat pump technology, and built a large number of water-source heat pumps that utilize surface water such as river water and lake water and groundwater, which have achieved good energy-saving and emission-reduction effects. However, due to the limitation of groundwater, there are obstacles to the promotion of water-source heat pumps. In addition, water source heat pumps have requirements on the inlet water temperature. For surface water below 4°C, the evaporator may freeze and automatically shut down during use. However, rivers in northern my country freeze in winter, and rivers with small flows and lakes in the south have relatively low temperatures, making them unsuitable as low-temperature ...

Problems solved by technology

The current ice-storage central air-conditioning system uses a conventional chiller to freeze the water in the ice storage tank through the evaporator at night. During the day, the ice melts into water. The chiller is turned off, and the water pump is turned on to send cold water to the end of the air-conditioning system for cooling. Valley electricity price, ice storage air-conditioning system does not have ice-water separation device
