Explosion-proof device for biomass gas production

Abstract

The invention discloses an explosion-proof device for biomass gas production, wherein the explosion-proof device for biomass gas production comprises a gasification furnace, an injection water pump, a water inlet pipe, an evaporation pipe and a whistling alarm device; a first valve is arranged at the communication part of a steam outlet pipe and a three-way connecting pipe, and a second valve is arranged at the communication part of a main gas outlet pipe and the three-way connecting pipe; a flashing light alarm device comprises a first installation cylinder, a first spring, a first sliding stop block, a first safety pipe and a first membrane; the whistling alarm device comprises a second installation cylinder, a second spring, a second sliding stop block, a second safety pipe and a second membrane; and a whistle comprises a whistle base, a reed base, a reed and an air outlet cavity pipe. A temperature sensor detects the temperature of biomass gas produced in the gasification furnace, high-pressure steam of a high-pressure steam storage tank is used for removing blockages in the main gas outlet pipe, the blockages are removed, faults are simply and rapidly removed, and thus workers are safely and orderly arranged for overhaul and maintenance.

Description

technical field [0001] The invention relates to the field of biomass gas production, in particular to an explosion-proof device for biomass gas production. Background technique [0002] Biomass gasifier produces a green new energy by cracking crop stalks, forest waste, etc. These green new energy have the advantages of cleanliness, sanitation, and are very popular among users, and they are very convenient to use, so they are widely used , but in the process of use, due to the external air temperature, the internal reaction of the equipment, the generation of a large amount of heat such as gas combustion, the temperature of the equipment will rise. Once the specified temperature is exceeded, the gas inside the equipment will easily explode, which is very dangerous. Therefore, in use, there is a certain potential safety hazard.

[0002] Biomass gasifier produces a green new energy by cracking crop stalks, forest waste, etc. These green new energy have the advantages of cleanliness, sanitation, and are very popular among users, and they are very convenient to use, so they are widely used , but in the process of use, due to the external air temperature, the internal reaction of the equipment, the generation of a large amount of heat such as gas combustion, the temperature of the equipment will rise. Once the specified temperature is exceeded, the gas inside the equipment will easily explode, which is very dangerous. Therefore, there are certain safety hazards when using

[0003] Biomass gasification technology can be divided into two categories, one is fixed bed gasification furnace technology, and the other is fluidized bed gasification furnace technology. No matter what kind of gasification furnace is used, its purpose is to carry out biomass gasification reaction, and then produce gas, which can be purified according to needs to obtain high-quality gas, and can also be directly transported to downstream gas equipment through gas pipelines at high temperatures. A large amount of gas is produced in the gasifier, which will inevitably lead to pressure in the furnace. Sudden changes, the existing technology usually adopts quick cut-off and pressure relief protection to prevent safety accidents such as explosions in the gasifier, but the working process is too complicated, it is not convenient for inspection and maintenance, and the production cost is too high, so it is not easy to promote
