Biomass material lock and working method

Abstract

The invention provides a biomass material lock and a working method. Blockage, high temperature flue gas backflow and other problems of a biomass feeding system appear, not only are the operation of abiomass incinerator or a biomass gasifier influenced, but also feeding system catching fire, even explosion, and other safety accidents are caused. The biomass feeding lock includes a shell (1), a discharge valve (2) is installed in the shell, and the discharge valve is connected with a feeding valve (3) through a drive mechanism (4); the shell is correspondingly connected with a primary pressurecharging and relief pipeline (5), a secondary pressure relief pipeline (10), an air seal pipeline (14), wherein the primary pressure charging and relief pipeline is connected with a buffer tank (7),the secondary pressure relief pipeline is correspondingly connected with a dust remover (12), and a secondary pressure charging pipeline (8); and the feeding valve and a material level monitor (13) are installed in the shell, the material level is located at the top of the interior of the shell, the feeding valve is connected with the discharge valve (2) through the drive mechanism (4), and the material level monitor is installed at the top of the interior of the shell. The biomass material lock and the working method are used in a feeding system of biomass power generation.

Description

Technical field: [0001] The invention relates to a biological material lock. Background technique: [0002] Biomass power generation technology is an advanced energy-saving and environmentally friendly power generation technology. According to the technical route, it is divided into biomass direct combustion power generation technology, biomass co-combustion power generation technology and biomass gasification power generation technology. The stability and safety of the biomass feeding system have high requirements. If there are problems such as blockage and high-temperature flue gas backflow in the biomass feeding system, it will not only affect the operation of the biomass incinerator or biomass gasifier, but also Cause the feeding system to catch fire or even explode and other safety accidents. [0003] There are still two problems in the existing biomass feeding system: (1) Blockage of the feeding system: most biomass power generation systems require the continuity of t...

According to the technical route, it is divided into biomass direct combustion power generation technology, biomass co-combustion power generation technology and biomass gasification power generation technology. The stability and safety of the biomass feeding system have high requirements. If there are problems such as blockage and high-temperature flue gas backflow in the biomass feeding system, it will not only affect the operation of the biomass incinerator or biomass gasifier, but also Cause safety accidents such as fire or even explosion in the feeding system

[0003] There are still two problems in the existing biomass feeding system: (1) Blockage of the feeding system: most biomass power generation systems require the continuity of the feeding, if there is a blockage, it will cause the biomass incinerator or biomass Large fluctuations in the working conditions of the gasifier or even shutdown will cause irreparable losses to production; (2) High-temperature flue gas backflow: For some boilers with frequent pressure fluctuations, especially positive pressure furnaces, if the sealing of the feeding system is not good, It is very likely that the high-temperature flue gas in the furnace will flow back to the feeding system, which will ignite the biomass material, burn the feeding system or even cause an explosion
