Problems solved by technology

However, since the diameter of the slag discharge pipe 02 is relatively small, the gasification agent enters the slag discharge pipe 02 and enters the gasification furnace 01 from the slag discharge pipe 02 before achieving uniform distribution, so the ash is cooled by the gasification agent less homogeneous and therefore less effective cooling

Abstract

The invention discloses a fluidized bed gasification device, which relates to the technical field of coal gasification. The invention is invented to solve the problem that the existing ash cooling device easily leads to abnormal slag discharge or low cooling uniformity. The fluidized bed gasification device of the present invention comprises a gasification furnace, the gasification furnace is connected with a slag discharge pipe, the slag discharge pipe is connected with a slag hopper, and at least one slag discharge inlet pipe is pierced on the slag hopper , the slag discharge inlet pipe is located above the ash in the slag hopper, and is used to feed gasification agent, and the gasification agent can enter the slag discharge pipe from the slag hopper and enter along the slag discharge pipe The gasifier is used to control the slagging rate of the gasifier and cool the ash. The fluidized bed gasification device of the present invention can be used to prevent abnormal slag discharge and improve cooling uniformity at the same time.

Description

technical field [0001] The invention relates to the technical field of coal gasification, in particular to a fluidized bed gasification device. Background technique [0002] In the field of coal gasification technology, the fluidized bed gasification device can produce high temperature ash. In order to avoid the ash from damaging the transportation equipment or causing injury to the operator, it is necessary to cool the high temperature ash discharged from the fluidized bed gasification device. deal with. [0003] As an example, a cooling treatment method in the prior art is to pass the ash discharged from the fluidized bed gasification device into a cooler for cooling, such as figure 1 As shown, the fluidized bed gasification device includes a gasifier 01, the gasifier 01 is connected to a slag discharge pipe 02, and the slag discharge pipe 02 is connected to a slag hopper 03, and pulverized coal is produced after gasification reaction in the gasifier 01 The ash and slag ...
