Problems solved by technology

This patent uses a solid-liquid fluidized bed and a cyclone desanding process for on-line ice production and deicing. Although it is theoretically established, in actual operation, because the ice layer is formed quickly and the ice layer is thick, under the impact of sand , it is difficult to be stripped off in a timely and effective manner, and it is difficult to achieve continuous extraction of solidification heat for heating

Abstract

The invention discloses a solidified latent heat acquiring device and a system, belongs to the technical field of energy, and aims to provide the solidified latent heat acquiring device and system for realizing extraction of solidified latent heat from cold water for external heating. The device consists of a heat exchange pipe, a pipe row, a cold water runner, a scraper, a left header, a right header, a motor, a speed reducer and a main shaft; and the system consists of a heat pump unit, the solidified latent heat acquiring device, a molten ice heat exchanger and a water pump, which are communicated through pipelines. The characteristic of releasing solidified latent heat when changing water to ice is used; a low-temperature heat exchange medium is used for exchanging heat with water to ice; the molten ice heat exchanger is used for melting an ice layer on the pipe wall of a heat exchange pipe for falling; and the ice is mechanically crushed, and is timely and effectively discharged from the heat exchanger, so that the continuous circulation of water icing, deicing, ice discharge and reicing is realized, and the continuous extraction of cold water solidified latent heat for heating by a heat pump system is guaranteed. The solidified latent heat acquiring device and system are suitable for heat pump heating systems for extracting cold water solidified latent heat.

Description

technical field [0001] The invention relates to a collection device and system for collecting latent heat of cold water solidification by using heat pump technology to release latent heat for external heating when cold water freezes, and belongs to the field of energy technology. Background technique [0002] Using heat pump technology to develop low-grade renewable clean energy for cooling and heating of buildings is one of the effective ways to save energy and reduce emissions, and has huge energy-saving, environmental protection and economic value. The use of heat pump technology to extract solidification latent heat for external heating has the following advantages in application: First, my country has a huge amount of surface water resources, but the water temperature is very low in winter, the lowest is about 2-4 °C, and the sensible heat energy available at this time The space is already very limited, and the extraction of solidification latent heat for heating can mak...
