A solar thermal insulation water tank with double exhaust function for low temperature environment

Abstract

The invention discloses a solar thermal insulation water tank with double steam exhaust functions for low temperature environment, which comprises a water tank shell, a water tank liner, a thermal insulation layer, a water inlet pipe, a water outlet pipe, a sewage pipe, and a heat collection pipe. There is an insulation layer between the water tank shell and the water tank liner. The end of the water tank shell is provided with a water inlet pipe and an outlet pipe that penetrates the insulation layer and communicates with the water tank liner. The bottom of the water tank shell is provided with a penetrating insulation layer and a water tank. The sewage pipe and the heat collecting pipe connected to the inner tank, among them, the steam exhaust device and the auxiliary steam exhaust device penetrating the water tank shell and the water tank inner tank are installed in the insulation layer on the top of the water tank. The structure of the device is stable and reasonable, and the installation of the steam exhaust pipe Reliable and stable, it can prevent the exhaust pipe from rusting, increase the service life of the exhaust pipe, reduce the cost of use, increase the insulation effect of the incubator, and reduce the loss of hot water heat. The set control valve can ensure the pressure balance in the water tank. Prevent the water tank from being destructively damaged by atmospheric pressure.

Description

technical field [0001] The invention relates to the field of construction, parts or accessories of solar heat collectors in heat generation and utilization not included in other categories in heat supply in mechanical engineering, especially a kind of solar thermal insulation with double exhaust function for low temperature environment water tank. Background technique [0002] As an energy-saving and environmentally friendly water heater, solar water heaters have entered thousands of households. Solar water heaters are mainly composed of heat collectors, circulation pipes and water tanks. Its main principle is to use the heat collector to collect sunlight and convert it into heat energy, and heat the water and store it in the thermal water tank for people to use. The solar heat preservation water tank is a kind of anti-pumping solar water tank device with exhaust device used in solar concentrated hot water or solar heating projects to collect and store the hot water genera...

AI Technical Summary

Problems solved by technology

[0004]1. When the temperature inside the water tank is higher than the atmospheric temperature outside the water tank, the hot water vapor in the water tank will be discharged from the exhaust pipe, which will cause the heat of the hot water Loss, the insulation effect is weakened

Especially in winter, when the light time is limited, it will lead to heat loss, which has a more obvious impact on the heat preservation effect of the water tank;

[0005]2. Most of the exhaust pipes are made of metal materials, which are prone to rust after a certain period of time. Reduce the service life of the exhaust pipe;

[0006]3. At present, most exhaust pipes are simply fixedly connected to the water tank and most of them are exposed to the external environment. , easy to loosen and cause the water tank to leak, which will lead to a great waste of water resources;

[0007] 4. In areas where the temperature is 0°C in winter, the water accumulation section of the exhaust pipe on the insulation water tank will freeze. When people use hot water, the unmelted ice will block the outlet of the exhaust pipe, causing the water tank of the water heater to be in a negative pressure state. It is easy to cause the water tank to be flattened by the atmosphere and deflate, which will cause destructive damage to the water heater tank and greatly waste resources
