Problems solved by technology
[0002] The coal gasifier currently on the market enters the gasification raw material from the feeding port, but because the feeding speed is not well controlled, it is easy to cause the material to accumulate at the raw material drop port, and the air inlet pipe is at the lower part of the furnace, so the oxygen content required for combustion is not enough. Good control will lead to incomplete combustion of raw materials. If the amount of oxygen is small, it will cause problems such as partial flameout and combustion voids. As the operation progresses, the consumption of raw materials will not be complete, resulting in excess gas leakage. If it is not handled in time, the It will mix with gas, resulting in high impurity content in gas

The invention relates to a coal gasifier which comprises a storage bin and a hearth. A raw material falling opening is arranged at the bottom of the storage bin and is communicated with the interior of the hearth; a feed opening is formed at one side of the top of the storage bin; multiple pairs of downward slide plates are obliquely arranged at two sides in the storage bin; an air inlet pipe is arranged at one side of the bottom of the hearth; an oxygen replenishment disk is arranged at one end, extending into the hearth, of the air inlet pipe; an ash falling port is formed at the bottom of the hearth below the oxygen replenishment disk and is communicated with an ash storage chamber; brush hair is distributed on the ash falling port; a brush hair control switch is arranged on the ash storage chamber; an ash discharge opening is formed at the bottom of the ash storage chamber; a cavity is arranged between the storage bin and the hearth; the right side of the cavity is connected with a coal gas outlet pipe; the upper part of the cavity is communicated with a water tank; the upper part of the water tank is connected with a water injecting pipe; and the coal gas outlet pipe is connected with a condenser which is communicated with a vacuum dryer. The coal gasifier has the advantages of uniformity in feeding, thoroughness in burning and high conversion rate.

As the operation progresses, the consumption of raw materials will not be complete, resulting in excess gas leakage. If it is not handled in time, the It will mix with gas, resulting in high impurity content in gas. Therefore, an improved technology is urgently needed to solve this problem.
