Charbon Chimique

Le matériau poreux en métal fritté produit par Shinkai a été largement utilisé dans l’industrie chimique du charbon.
La Chine est un pays riche en ressources charbonnières. Les industries de l’énergie du charbon et de la chimie joueront un rôle important dans l’utilisation durable de l’énergie. Dans l’exploration et la recherche continues de la nouvelle industrie chimique du charbon, des technologies telles que la gazéification du charbon en poudre sous pression, le charbon en pétrole, le charbon en oléfines et le charbon en méthanol ont été largement produites et appliquées dans les entreprises nationales, ce qui est d’une grande importance pour réduire l’environnement causé par la pollution de la combustion du charbon et réduire la dépendance à l’égard du pétrole importé. Les éléments poreux en métal fritté de Shinkai ont été largement utilisés dans l’industrie chimique du charbon.”

There is a pulverized coal conveying system in the pulverized coal gasification unit such as HT-L, SHELL, or GSP. The gas conveying medium is nitrogen or carbon dioxide. An important component of this technology is the pressurized feeding system of pulverized coal. When nitrogen is used for pressurized conveying of pulverized coal, since the particle size of the pulverized coal is very small, the adhesion phenomenon is likely to occur during the flow of the particles, resulting in bridging problems. After the ventilation cone device is added, the nitrogen gas can enter the tank through the ventilation cone at the bottom of the powder coal discharge tank, and the powder in the storage tank is pressurized to homogenize the powder, thereby reducing the force between the powders, making the particles flow smoothly.

Pipeline purging also plays an important role in the pressurized conveying of pulverized coal. When the pulverized coal enters the pipeline, the pulverized coal is easily piled up under the condition of high pressure, the pipeline is clogged, so the coal cannot be smoothly conveyed, and the addition of the pipeline purging device in the conveying pipeline effectively solves this phenomenon. The principle is that the gas passes through the micropores in the pipe purifier, and a uniform thin gas film is formed on the inner wall of the purifier, so that the split body is in a suspended fluidized state and smoothly flows into the lower end conveying pipe, thereby avoiding powder accumulation and making the conveying effect is more efficient.
