Description

an insulated greenhouse

technical field

The invention relates to a thermal insulation greenhouse.

Background technique

Traditional thermal insulation greenhouses either use fuel heating methods or pure electric heating structures, resulting in large power consumption, which not only increases production costs, but also affects energy conservation and environmental protection.

On the other hand, shallow surface thermal energy technology (also known as ground energy, including the energy of groundwater, soil or surface water, etc.), refers to the energy in the earth's interior that has development and utilization value under the current technical and economic conditions within a certain depth range below the surface. thermal energy resources. Shallow geothermal energy is a part of geothermal resources, and it is also a special mineral resource. Its energy mainly comes from solar radiation and the gradient warming of the earth. It can heat buildings and save energy by 50% to 60% compared with conventional heating technologies. , The operating cost is reduced by about 30% to 40%.

Shallow geothermal energy has wide distribution, large reserves, rapid regeneration and high utilization value. Shallow geothermal energy in China is mainly utilized and collected mainly through ground source heat pump technology. Not only can it meet the heating demand, but also directly reduce the amount of pollution emitted, which is conducive to protecting the environment. However, the cost of using ground source heat pump technology is too high, which increases the production cost and is not conducive to the comprehensive promotion of shallow surface heat energy technology.

So far, the prior art may have dabbled around many aspects of the present invention, but the design of directly applying the heat source of shallow surface heat energy to the thermal insulation greenhouse has not been seen.

The fan, air inlet pipe, shallow surface The heat energy collection pipe, the air outlet pipe, the airflow dryer and the fan are connected in sequence, the fan is arranged outside the heat preservation greenhouse, and is sealed and connected with the shallow surface heat energy collection pipe through the air inlet pipe, and the shallow surface heat energy collection pipe The pipe is buried in the underground soil with a depth of 120-1000 meters on the shallow surface, and it is used to collect geothermal energy with a temperature not lower than 30 degrees, and the geothermal energy is filled with the shallow surface heat energy collection pipe (21) The air in the heat exchange is carried out, the other end of the shallow surface heat energy collection pipe is sealed and connected with the air outlet pipe arranged outside the shallow layer surface, and the airflow dryer is arranged between the air outlet pipe and the fan in the thermal insulation greenhouse , its role is to filter and dry the hot air in the air outlet duct, and the air heated by shallow geothermal energy passes through the air outlet duct and the airflow dryer, and then is transmitted to the greenhouse by the fan in the thermal insulation greenhouse for use.

The beneficial effects of the present invention are:

Compared with the prior art, the present invention provides users with a device with simple structure and reasonable design, which can effectively realize the direct utilization of shallow surface heat energy. In the present invention, the fan directly sends air to the shallow surface heat collection pipe buried in the shallow surface soil, so that the air filled in the shallow surface heat collection pipe exchanges heat with the shallow surface heat source, and the heat from the shallow surface The air coming out of the ground surface heat energy collection pipe is hot air, which can be used for heating, which greatly saves energy.
