Embodiment Construction
[0028] In order to make it easy to understand the technical means, creation features, achieved goals and effects of the present invention, the present invention will be further described below with reference to the specific embodiments.
[0029] like Figure 1-Figure 7 As shown, a coal chemical pressurized gasifier according to the present invention includes a furnace body 1, a jet mechanism 2, a heating mechanism 3, a cooling mechanism 4, a driving mechanism 5, an exhaust mechanism 6, a blocking mechanism 7 and a pressurization mechanism valve 8, the bottom end of the furnace body 1 is installed with the air jet mechanism 2 for adding gasification agent to the pulverized coal, and the exhaust mechanism 6 for exhausting gas is installed on the side wall of the furnace body 1; The top of the furnace body 1 is internally slidably connected to the blocking mechanism 7 used to block coal dust from entering the exhaust mechanism 6; The driving mechanism 5, the cooling mechanism 4 ...

The invention relates to the technical field of coal chemical industry, in particular to a coal chemical industry pressurized gasification furnace which comprises a furnace body, a gas injection mechanism, a heating mechanism, a cooling mechanism, a driving mechanism, an exhaust mechanism, a blocking mechanism and a pressure increasing valve. The blocking mechanism retains pulverized coal in the furnace body, coal gas penetrates through the blocking mechanism and is exhausted from the interior of the furnace body through the exhaust mechanism, at the moment, the driving mechanism continuously moves to push the pulverized coal to continuously fall into the furnace body, meanwhile, the driving mechanism drives the blocking mechanism to continuously move upwards, and the exhaust mechanism is blocked when the blocking mechanism moves upwards. The coal gas in the furnace body is stored in the top end of the furnace body, and when the blocking mechanism block needs to move to the highest point, the upward movement speed of the blocking mechanism is suddenly increased, so that the coal gas in the top end of the furnace body quickly moves downwards to backflush the blocking mechanism, and the blocking mechanism is prevented from being blocked by coal powder.
Description
technical field [0001] The invention relates to the technical field of coal chemical industry, in particular to a pressurized gasifier for coal chemical industry. Background technique [0002] Coal gasifier, also known as gas generator, is a furnace that uses coal as gasification fuel to produce combustible gas; when producing gas, gasification agent continuously enters the gasifier from the bottom, and the generated coal gas is discharged from the gasifier. Top out. [0003] In the process of gas production, pulverized coal is continuously added from the top of the gasifier, and the generated gas pushes the pulverized coal upwards into the exhaust pipe, which is easy to cause blockage of the exhaust pipe and waste of pulverized coal. [0004] The above information disclosed in this Background section is only for enhancement of understanding of the background of the disclosure and therefore it may contain information that does not form the prior art that is already known to...
