Vertical carbon-dioxide generator for greenhouse

Abstract

The invention relates to a gas generating device, in particular to a vertical carbon-dioxide generator for a greenhouse with the purpose of solving the technical difficulty that carbon dioxide generators in the same kind are high in energy loss. The vertical carbon-dioxide generator comprises a thermal decomposition reactor and an ammonia absorber. The top end of the thermal decomposition reactor is provided with a feeding sealing cover. The bottom of the thermal decomposition reactor is provided with a heater. The side wall of the thermal decomposition reactor is provided with a waste discharge valve and a mixed gas pipe. The mixed gas pipe and the ammonia absorber are communicated. The side wall of the ammonia absorber is provided with a liquid level pipe, a water-adding valve, an ammonia water discharge valve and a carbon-dioxide exhaust pipe. The interior of the ammonia absorber is provided with a millipore filter communicated with the mixed gas pipe.The vertical carbon-dioxide generator for the greenhouse has following beneficial effects: by heating ammonium bicarbonate, carbon dioxide is produced and gas is produced at high speed; by means of a pressure adjusting system, uniform gas distribution at long distance can be achieved; the problem that a technical product in the same kind may have energy dissipation due to the need of air pump pressurization is solved; the vertical carbon-dioxide generator is adapted for greenhouses with all specifications; and carbon dioxide can be supplemented to multiple greenhouses in a unified way at the same time.

Description

Technical field: [0001] The invention relates to a gas generating device, in particular to a greenhouse vertical carbon dioxide generator. Background technique: [0002] The greenhouse is the main cultivation facility for the normal growth of vegetables and fruits in the cold season of winter and spring. The greenhouse solves the problems of temperature, light, fertilizer and water required for plant photosynthesis, but the problem of carbon dioxide supplementation in confined spaces is not very good. Solved, the problem of serious shortage of carbon dioxide in the shed cannot be completely solved by short-term ventilation. Artificially supplementing carbon dioxide is the most effective measure to enhance the photosynthesis of vegetables and fruits in greenhouses. Carbon dioxide generators are widely used in greenhouses around the world as equipment for producing and providing carbon dioxide. There are three main types of carbon dioxide generators for greenhouses on the mar...

Problems solved by technology

However, it realizes the long-distance transportation of gas through the pressurization of the air pump. While realizing this function, it increases the pressure of the thermal decomposition reactants, thereby increasing the decomposition temperature, and requires more heat to complete the decomposition of the same mass of raw materials. Decomposition

Plus the energy consumption of the air pump itself, resulting in a lot of waste
