Problems solved by technology

In addition, there are inflatable cones made of sintered metals, but this kind of inflatable cones cannot withstand excessive pressure. The current production of inflatable cones can only withstand a maximum internal and external pressure difference of 1.0Mpa, and in the actual production process often due to pressure If the difference is too large or working in an environment with a large pressure difference for a long time, the inflatable cone will be blown out, resulting in parking and affecting production

Abstract

The invention disclose an air inflation awl for a pulverized coal gasification device. The air inflation awl comprises a taper-shaped barrel and a reinforcement part, wherein the taper-shaped barrel is provided with at least one air inflation area made of sintering metal; the reinforcement part is arranged on the wall of the taper-shaped barrel and at least covers the air inflation area; and a plurality of through holes are formed in the reinforcement part. According to the air inflation awl for the pulverized coal gasification device, which is disclosed by the embodiment of the invention, the strength of the air inflation awl is improved by arranging the reinforcement part covered on the air inflation area, so that the air inflation awl can bear a higher internal and external pressure difference, the highest internal and external pressure difference of 1Mpa, which can be borne by the traditional air inflation awl, is improved to 5Mpa so as to greatly lower the damage possibility of the air inflation awl and prolong the service life of the air inflation awl to lower the cost, meanwhile, the parking times of the air inflation awl are reduced, and the production efficiency is improved. In addition, according to the air inflation awl disclosed by the embodiment of the invention, the phenomenon that the pulverized coal flows back can be effectively prevented, and the pulverized coal conveying effect is guaranteed.

Description

Technical field [0001] The present invention relates to the technical field of coal gasification, in particular to an inflation cone of a powder coal gasification device. Background technique [0002] Coal gasification, such as the pressurized gasification of pulverized coal, is a clean coal combustion technology developed in recent years and has been more and more widely used. [0003] There are many traditional pulverized coal gasifiers for coal gasification. In the pressurized gasification process, pulverized coal transportation has a significant impact on the operation of the gasifier. Traditionally, in the pressurized gasification process, dense phase transportation is commonly used to transport dry pulverized coal from the coal storage tank to the gasifier. The transportation of pulverized coal in the pulverized coal storage tank is mainly based on the principle of gravity flow. The pulverized coal storage tank is arranged from top to bottom according to the requirements of ...
