Heating, carburizing and water charging system for plant greenhouse, and plant greenhouse shack

Abstract

The invention discloses a heating, carburizing and water charging system for a plant greenhouse. A radiating pipe is connected to the tail end of a fire tail of a methanol combustor, a hot air dual-outlet pipeline is connected to the tail end of the radiating pipe, and a fluid regulating valve is mounted at the confluence part of the hot air dual-outlet pipeline; a carbon dioxide sensor, a temperature sensor and an oxygen sensor are connected to a controller through an electric wire, the controller controls combustion power to control the diffusion heat energy of the radiating pipe to adjust the temperature in the greenhouse, and best growth temperature required by plants is achieved; and the controller controls the opening proportion of the fluid regulating valve to regulate the content of carbon dioxide in the greenhouse, so that the best growth carbon dioxide required by the plants is met as possible; and the oxygen sensor is mounted at the fire tail of the methanol combustor, and the controller regulates the combined combustion proportion of fuel gas and air through the oxygen sensor to achieve the set combustion state, and pollutant discharge is reduced.

Description

technical field [0001] The invention relates to a plant planting and cultivating device, in particular to a plant greenhouse heating, carbon-increasing and water-replenishing system and a plant greenhouse shed. Background technique [0002] With the improvement of people's living standards, everyone has become accustomed to eating big fish and meat, and the demand for fresh vegetables has skyrocketed. In winter, due to the cold weather, especially for vegetable greenhouses and flower planting in severe cold areas, because the outdoor temperature is low and the peripheral wall structure of the vegetable greenhouse is not good, the outdoor cold air will enter the greenhouse through conduction, causing indoor The low temperature affects the growth of vegetables and flowers. If the greenhouse is not heated, it will directly affect the economic income of farmers. Now many greenhouses in winter use natural heat energy brought by natural light. Natural light and heat are transmitt...

Problems solved by technology

In winter, due to the cold weather, especially for vegetable greenhouses and flower planting in severe cold areas, because the outdoor temperature is low and the peripheral wall structure of the vegetable greenhouse is not good, the outdoor cold air will enter the greenhouse through conduction, causing indoor The low temperature affects the growth of vegetables and flowers. If the greenhouse is not heated, it will directly affect the economic income of farmers

Now many greenhouses in winter use natural heat energy brought by natural light. Natural light and heat are transmitted to the greenhouse through the light film of the greenhouse, and the principle of heat storage in the greenhouse is achieved through the closure of the outer protective wall of the greenhouse. According to the actual situation of the greenhouse, this phenomenon increases the temperature of the space in the greenhouse. The increase in the temperature of the space in the greenhouse can only provide light and effect to the leaves and stems of the plants. The fundamental growth source of plant growth is the nutrients and water in the soil absorbed by the plants. In this case, the temperature of the space in the shed is high and the temperature of the ground where the roots of the plants are in the soil is relatively low, so it cannot satisfy the natural growth of many vegetables and fruits at all, and there is no carbon dioxide planting
