Greenhouse heat supply system

Abstract

The invention relates to the technical field of greenhouses, in particular to a greenhouse heat supply system. The system comprises: a reverse combustion coal-fired boiler, a heat medium box, a heat dissipation assembly, a heating pipeline pump, and a loop assembly. The reverse combustion coal-fired boiler is used for heating or increasing the temperature of a medium in the heat medium box; the reverse combustion coal-fired boiler, the heat medium box, the heating pipeline pump, the heat dissipation assembly, and the loop assembly form a circulation system. The reverse combustion coal-fired boiler is an economical and efficient coal-fired boiler, and compared with traditional northern greenhouse heating, the fire coal is saved, and the cost is saved; the heat dissipation assembly is good in heat dissipation condition and fast in heat conduction, can ensure the balance of the temperature in a greenhouse, and has small influence on the growth of surrounding crops; the loop assembly can reduce heat loss in the greenhouse to the maximum extent, and the purpose of saving energy is achieved. Therefore, the heat supply system for the greenhouse has the advantages of energy conservation, high efficiency and capability of ensuring the balance of the temperature in greenhouses.

Description

technical field [0001] The invention relates to the technical field of greenhouses, in particular to a heating system for greenhouses. Background technique [0002] my country is the country with the earliest origin of greenhouse cultivation, but compared with developed countries, there is still a considerable gap in greenhouse cultivation technology, especially in terms of greenhouse heating equipment, there are still many deficiencies. [0003] At present, my country's greenhouse heating equipment is mainly aimed at glass greenhouses, which are expensive to build and are mainly used to maintain high-priced crops such as flowers. For relatively low-cost vegetable greenhouses, the heating equipment is mainly indigenous heating, and there is no advanced system heating system. The indigenous heating method has the disadvantages of wasting fuel, unstable temperature in the greenhouse, difficult to control, and limiting the scale of the greenhouse. . Especially in northern my ...

AI Technical Summary

Problems solved by technology

[0011] Compared with the above heating methods, the greenhouses in northern my country are most suitable for hot water heating. Aiming at the shortcomings of high energy consumption and difficult control of hot water heating in the existing technology, an energy-saving, high-efficiency, and easy-to-control vegetable greenhouse heating is developed. The system can not only improve the disadvantages of traditional heating methods, but also increase the production period of vegetable greenhouses, increase the income of vegetable farmers, and have high economic benefits
