Cooling device for biomass gas production

Abstract

The invention discloses a cooling device for biomass gas production. The cooling device comprises an air compression fan, a first heat exchange tube, a second heat exchange tube, a third heat exchange tube, a fire grate and a fourth heat exchange tube, the fire grate comprises an outer connecting ring and a bearing plate, and the upper side of the outer connecting ring is fixedly connected to the edge of the lower side of a gas furnace tank body; the second heat exchange pipe comprises vertical heat exchange pipes and transverse heat exchange pipes, the multiple transverse heat exchange pipes are embedded in the middle of the tank wall of the gas furnace tank body at equal intervals, biomass fuel is added into a feeding port of the gas furnace tank body, air is introduced into the gas furnace tank body, and a second valve communicating with a first air supply pipe and a first communication pipe and a second valve communicating with a fourth communication pipe and a four-way pipe are opened, so that the gas furnace tank body is cooled, the opening number of the second valves and third valves is gradually increased, the opening number of fourth valves is increased, the temperature in the gas furnace tank body is guaranteed, the energy utilization rate is increased, and energy consumption is saved.

Description

technical field [0001] The invention relates to the storage field, in particular to a cooling device for biomass gas production. Background technique [0002] With the rapid development of industry and the rapid advancement of urbanization, energy shortages and environmental pollution have become the focus of attention in today's society. However, the phenomenon of burning straw and using old-fashioned wood stoves in rural areas still exists, and it also emits a lot of dust and greenhouses. At present, biomass energy waste is mainly crop waste, a large part of which can be used as energy. In addition, most of forestry and wood processing waste can also be used as energy. [0003] The biomass gas produced by the biomass gasifier belongs to green new energy and has strong vitality. Since the raw materials produced by biomass gas are crop straw, forest waste, edible fungus residue, cattle and sheep manure and all combustible substances, It is an inexhaustible and inexhaustible...

Problems solved by technology

[0004] Biomass gasification furnace is a commonly used biomass gas production equipment, but the current biomass gasification furnace is still in its infancy. Since the generation of biomass gas requires a high temperature of 1,200 degrees, it is necessary to protect the grate and furnace body To prevent the furnace body and grate from being damaged, but the existing cooling device is often a cooling oil device, which is very complicated and this part of energy is not used but lost, which cannot improve the utilization rate of energy, so it is necessary to improve the cooling device Redesign the heat exchange pipeline
