Buried heat storage tank

Abstract

The invention discloses a buried heat storage tank which comprises a tank body. The tank body is composed of a tank body wall, a tank body thermal insulation top cover and a tank body thermal insulation bottom plate. A thermal insulation pipe is adhered to the inner wall of the tank body, the thermal insulation pipe is arranged on the inner wall of the tank body in surrounding mode, a heat exchanger is installed in the tank body, a radiator and a heating device are fixedly installed in the tank body, and the thermal insulation pipe is composed of a polyvinyl chloride (PVC) pipe and polyurethane materials filled in the PVC pipe. The buried heat storage tank is buried under the ground and used for storing solar energy, and is simple to install, low in cost, rapid in installation speed, capable of storing the solar energy for a long time, good in thermal insulation effect and particularly suitable for a single family.

Description

technical field [0001] The invention relates to a heat storage tank, in particular to a heat storage tank buried underground and specially used for storing solar energy. Background technique [0002] At present, especially in the northwest region, in order to reduce people's living costs in rural construction, the government strongly encourages people to use solar thermal energy. In order to realize the long-term storage of solar thermal energy, the heat storage device is usually buried in a certain depth underground at present to avoid excessive heat loss of the heat storage device in the atmosphere. There are mainly methods such as building hot water storage pools underground and building underground heat storage tanks. However, both the heat storage pool and the heat storage store have the following deficiencies. [0003] 1. Building heat storage pools underground is technically difficult and expensive. Since water is easy to vaporize, water vaporization will carry a ...

AI Technical Summary

Problems solved by technology

[0005] First, there are many gaps in the thermal insulation enclosure structure of the underground heat storage storage built with smaller thermal insulation blocks, and the overall thermal insulation effect is poor

[0006] Second, there are too many construction procedures

The construction of the existing technology requires about a dozen processes, and there are too many processes, which is very complicated and troublesome

[0007] Third, it is impossible to continuously use mechanical operations

Excavation of foundation pit, filling of thermal storage materials, and backfilling all require the use of large-scale machinery and equipment (mainly excavators).

When the heat exchanger is arranged, only the mechanical operation can be stopped, resulting in low mechanical utilization

[0008] Fourth, it is labor-intensive and time-consuming, and the progress is slow

Too many processes, manual and mechanical cross-operation, resulting in a long construction period

Especially when it rains, the construction progress is very slow
