Directional water taking device for solar layered heat-storage water tank

Abstract

The invention discloses a directional water taking device for a solar layered heat-storage water tank. The directional water taking device for the solar layered heat-storage water tank comprises the heat-storage water tank. A solar heat-collection water supply end is connected to the top of the heat-storage water tank. A solar heat-collection water return end is connected to the side face of the bottom of the heat-storage water tank. A layered water taking device body is installed on the inner wall of the heat-storage water tank. A layered water taking opening is movably formed in the layered water taking device body and can move in the direction perpendicular to the horizontal plane. The interior of the layered water taking device communicates with a heating water supply end stretching out of the heat-storage water tank. The heating water supply end is connected to the side face of the bottom of the heat-storage water tank. Water in the heat-storage water tank enters the layered water taking device from the layered water taking opening and is supplied to users through the heating water supply end. According to the directional water taking device for the solar layered heat-storage water tank, layered water taking can be conducted according to the requirement of the users for the water taking temperature. The directional water taking device for the solar layered heat-storage water tank is simple in structure and flexible in operation, the problems of an existing solar heat-storage water tank can be effectively solved, and the purpose of layered water taking is achieved.

Description

technical field [0001] The invention belongs to the technical field of heat utilization of solar energy, and relates to a layered and on-demand water intake technology for solar heat storage tanks, in particular to a directional water intake device that can be changed according to the water temperature requirements of the heating system, which not only ensures the heat utilization effect of the user system, but also improves The efficiency of solar thermal utilization. Background technique [0002] Most of the heating areas in my country are rich in solar energy resources, and the use of solar energy for heating is a technology in line with the sustainable development strategy. However, in order to use solar thermal energy for heating, the shortcomings of solar periodicity and randomness must be overcome, and using heat storage devices to store and regulate heat is an effective way to solve this problem. Especially with the development of the national economy, the improveme...

Problems solved by technology

Due to the weather, the heat collected by the collector is different, which makes the heat storage of the hot water tank different, which will cause the temperature stratification to be different, which makes the water temperature supplied to the user fluctuate and is not easy to stabilize.

It can be said that this form of fixed pipeline will cause a mismatch between the temperature of the water supply and the needs of users.

This problem is more serious for large hot water storage tanks
