Abstract

The invention discloses a biomass gas generator, which comprises: a furnace shell and an inner shell, a heat insulation layer is arranged between the furnace shell and the inner shell, the bottom of the furnace shell is set as a conical ash outlet, and the bottom of the ash outlet is There is a conical ash collecting tray, and rolling wheels are installed on the feet of the ash collecting tray. The top of the furnace shell is provided with a feed inlet and a gas outlet. The inner shell is equipped with an upper grate and a lower grate. The upper part of the lower grate; the lower part of the furnace shell is provided with an air pipe connected with a blower and connected to the inside of the inner shell. The technical purpose of the present invention is to provide a biomass gasifier with higher gas production efficiency, more reasonable structure, and the ability to fully convert biomass into gas, so as to make more full use of straw and improve energy utilization.

Description

technical field [0001] The invention relates to the field of devices for producing gas from biomass, in particular to a biomass gas generator. Background technique [0002] my country produces hundreds of millions of tons of crop straw every year, and at the current stage of development, my country vigorously advocates energy conservation and emission reduction, so as to make my country's economy sustainable development. [0003] Usually, the stalks after harvesting crops are piled up in the field, but in many rural areas, people transport the harvested stalks home and directly burn them for cooking or directly burn the stalks in the field, resulting in air pollution and waste of stalks . Therefore, it is necessary to make the straw into gas and burn the gas for cooking or heating, so as to meet the requirements of environmental protection. Biomass energy, as the fourth largest energy source other than coal, oil, and natural gas, is an environmentally friendly, recyclable ...
