Novel biomass temperature and carbon increasing gasifier for greenhouse

Abstract

A novel biomass temperature and carbon increasing gasifier for a greenhouse comprises a combustion cavity. Air inlets and air outlets are formed outside the combustion cavity. A combustor is mounted on a fire resistant wall on the outer side of the combustion cavity. A heat exchanging pipe is arranged inside the combustion cavity and in a vertically-arranged S-shaped structure. One end of the heat exchanging pipe is inserted in the side wall of the combustion cavity, and the other end of the heat exchanging pipe is inserted in the fire resistant wall. The two sets of air outlets and air inlets are formed outside the combustion cavity. The first air inlet and the first air outlet are formed horizontally and distributed on the left and right sides of the combustion cavity correspondingly. The second air inlet and the second air outlet are formed vertically and distributed on the upper and lower sides of the combustion cavity correspondingly. The gasifier adopts the two sets of air inlets and air outlets, so that the temperature increasing speed is high, the heat supply efficiency and temperature increasing speed are increased, and the heat supply effect is improved.

Description

technical field [0001] The invention relates to a biomass gasifier, in particular to a novel biomass temperature-increasing and carbon-increasing gasifier for vegetable and fruit greenhouses. Background technique [0002] In the cold winter, in order to ensure the normal growth of the plants in the vegetable and fruit greenhouses, the managers of the vegetable and fruit greenhouses use biomass gasifiers to heat the greenhouses. Most of the existing biomass gasifiers use one-time combustion for heating, and there are many harmful gases in the generated flue gas. In the process of heating the shed, the content of harmful gases in the shed will be increased, which will affect the growth of plants; and now Although some biomass gasification furnaces have a long heating time, their heating speed is slow. The heat on the surface of the cavity needs to be heated up before the heat on the surface of the cavity can be gradually transported outward. In areas with large temperature dif...

Problems solved by technology

Most of the existing biomass gasifiers use one-time combustion for heating, and there are many harmful gases in the generated flue gas. In the process of heating the shed, the content of harmful gases in the shed will be increased, which will affect the growth of plants; and now Although some biomass gasification furnaces have a long heating time, their heating speed is slow. The heat on the surface of the cavity needs to be heated up before the heat on the surface of the cavity can be gradually transported outward. In areas with large temperature differences between day and night, the heating speed determines The heat preservation effect of the plants in the shed, if the speed is slow, will also affect the growth of the plants
