Biomass pyrolysis and gasification furnace

Abstract

The invention relates to a biomass pyrolysis and gasification furnace. The biomass pyrolysis and gasification furnace comprises a biomass gasification furnace body, a seal furnace lid, a gasificationchamber, a gas storage chamber, furnace grates, a wind inlet system and a furnace head. The gasification furnace body is divided into a heating chamber and the gasification chamber; the convex edge ofthe seal furnace lid is matched with a groove in the furnace body, and the seal furnace lid is fixed through thumb screws; a fuel distributor is arranged in the gasification furnace body; a filter screen is arranged at the communication position of the gasification chamber and the gas storage chamber; and the bottom of the gasification furnace is connected with a blasting system and an ash discharging opening, the furnace head is connected with a smoke discharging tube, a pyrolysis gas discharging tube is connected between the gas storage chamber and the smoke discharging tube, and one end ofthe pyrolysis gas discharging tube is inserted into the smoke discharging tube. The unique separate arrangement structure of the gasification chamber and the heating chamber in the invention can maximize the energy reserved by biomasses, increase the output of pyrolysis gas and realize the reutilization of the heat of smoke, and the installation of the filter screen realizes the preliminary purification of the pyrolysis gas and reduces the content of tar in the pyrolysis gas to a certain degree.

Description

technical field [0001] The patent of the present invention relates to a biomass pyrolysis gasification stove, especially for the clean utilization of agricultural solid waste such as rural straw and rice husk. Background technique [0002] As a traditional agricultural country, our country produces more than 900 million tons of crop straw every year. At present, the potential of my country's usable biomass resources to be converted into energy is about 500 million tons of standard coal. With the expansion of afforestation area and economic and social development, the potential of my country's biomass resources into energy can reach 1 billion tons of standard coal, accounting for 28% of my country's total energy consumption. In recent years, under the encouragement of a series of policies to support the utilization of straws issued by the state, the comprehensive utilization of straw resources has made great progress. Some straw resources are not fully utilized. Straw can b...

Problems solved by technology

[0003] Most rural households in my country still use traditional earthen pots. Although traditional earthen pots are simple to build and cheap, they have low fuel utilization and large floor space. They will generate a lot of smoke and dust during use, which will deteriorate the kitchen environment. There is a greater fire hazard

With the development of society, electrification has been generally realized in rural areas, but at present, the income of farmers in our country is single, and the cost of cooking and heating in daily life has increased the economic burden of farmers to a certain extent.
