Multi-point catalytic biomass gasifier

Abstract

The invention relates to a multi-point catalytic biomass gasifier, comprising a fuel bunker, a feed port on the side of the fuel bunker, a mixed gas bunker at the lower part of the fuel bunker, and an automatic slag discharger between the fuel bunker and the mixed gas bin. The reason is: the top of the fuel tank is equipped with a pressing system, the middle of the fuel tank is equipped with an inner cooling gas tank, the two sides are equipped with an outer cooling gas tank, a trapezoidal combustion chamber is set in the middle of the bottom, and a tower-type oxygen distribution plate is installed around the combustion chamber. An ignition hole is arranged above the air inlet pipe, an air outlet is arranged on the side of the upper part of the mixed gas chamber, a wood acetic acid discharge port is arranged below the air outlet, and a sewage discharge hole and a tar discharge hole are arranged at the bottom of the mixed gas chamber. Oxygen distribution plate can evenly deliver oxygen to the fuel tank. Multi-point catalysis speeds up the gas output, improves the gas production, saves biomass fuel, and meets the production needs of large gasifiers. Through rapid cooling, tar and gas are increased. The settling speed of dust makes the gas more pure.

Description

technical field [0001] The invention belongs to biomass gasification equipment, in particular to a multi-point catalytic biomass gasification machine with rapid gas production, large gas production capacity and fuel saving. Background technique [0002] At present, my country's energy consumption ranks first in the world, CO 2 Emissions are second only to the United States, and are expected to overtake the United States in 2015 to become the world's largest emitter. In addition, it is estimated that by 2020, my country's crude oil imports will reach 250 million tons, and natural gas will reach 150 billion cubic meters, surpassing my country's 50% of energy consumption, my country's excessive dependence on imported energy directly threatens my country's energy security. With the rapid growth of energy consumption, the extensive use of fossil fuels will bring serious environmental pollution and ecological damage, resulting in frequent occurrence of smog air and heavy metal pol...

Problems solved by technology

However, the existing biomass gasifiers still have the following disadvantages: 1. The catalytic efficiency of the gasifier is low, and the gas production rate is slow, which increases the consumption of gas by cracking, which seriously restricts the development of large-scale biomass gasifiers ;2. The bulk density of raw materials in the fuel bunker is too low, resulting in uneven gas production and low gas production, which reduces the utilization rate of biomass raw materials; 3. The high tar content in the gasification process reduces the energy of combustible gas. After burning, it will produce harmful gas to the human body, which will seriously damage the gas utilization equipment and increase the maintenance cost of the equipment
