Problems solved by technology

In the existing gas station layout, the gas stations are scattered in different locations of the factory area, and the fuel supply of each gas station has its own coal storage, crushing transfer station and conveyor belt, which will inevitably lead to redundant construction of the factory's coal fuel supply system , increase the factory land area, road paving area, pipeline laying length and factory infrastructure investment
In addition, because the coal depots are scattered in different locations in the factory area, it is inconvenient to manage. At the same time, coal trucks are running around the factory area, which has a great impact on the production environment of the factory.

Embodiment

[0011] Embodiment: As shown in Figure 1, when designing the layout of the factory, firstly, according to the source direction of the fuel coal of the factory, the local meteorological conditions and the location of the gas user, etc., the overall planning of the gas station system is arranged in a place where the factory can be in the downwind direction for a long time One corner of the factory area, and a side door is opened at this corner to reduce coal pollution to the factory area environment. Then the coal gas generating device 4 is gathered together and arranged at one end of the factory area. The gas generating device 4 is composed of a phase-one gas generating device 4-1, a second-phase gas generating device 4-2, and a third-phase gas generating device 4-3. It is composed of the n-stage gas generating device 4-n, and the first-stage gas generating device 4-1 and the third-stage gas generating device 4-3 are built in a row, and the second-stage gas generating device 4-2 ...

Abstract

The present invention discloses configuration method of coal gas station for alumina plant. The configuration method of coal gas station includes coal gas generating sets concentrated in one end of the plant and arranged in two rows, coal storages concentrated in the other end of the plant and arranged in one row, one combined coal conveying belt between the coal gas generating sets and the coal storages, two combined coal conveying belts in the coal storages, three-port transfer stations to connect these three combined coal conveying belts, and coal conveying belts to connect each of the coal gas generating sets or coal storages to nearest four-port transfer station or three-port transfer station. The present invention has lowered engineering cost and running cost, saving in land and good alumina plant environment.

Description

technical field [0001] The invention relates to a method for configuring the serial layout of a gas station in an alumina plant, and belongs to the technical field of equipment layout configuration structure of a gas station in an alumina plant. Background technique [0002] In the general layout design of the factory, land reservation for expansion is a major issue. The quality of its arrangement not only affects the production of the factory, but also affects the construction and infrastructure investment, production management and production investment of the factory. Production process in alumina plant [0003] Aluminum hydroxide needs to be calcined to remove its attached water and crystallization water. In order to ensure the purity of alumina, heavy oil or gas is usually used as fuel in the calcination process. In areas that lack heavy oil as fuel, gas stations are generally set up to generate gas for aluminum hydroxide calcination. The existing gas station producti...
