Problems solved by technology

The existing boiler rooms are not well laid out. The boiler rooms are scattered and arranged in different locations in the factory area. Each boiler room has its own coal storage, crushing station, transfer station and conveyor belt for fuel supply, which will inevitably cause coal fuel in the factory. The repeated construction of the supply system will increase the area of ​​the factory area, increase the area of ​​road paving and the length of pipeline laying, and increase the investment in factory infrastructure
In addition, because the coal depots are scattered in different locations in the factory area, it is inconvenient to manage, and coal trucks are running around in the factory area, which has a serious impact on the production environment of the factory

Embodiment

[0010] Example: As shown in Figure 1, during the factory layout design and initial planning, firstly, the overall planning of the coal supply system is laid out in the factory according to factors such as the source direction of the coal source of the aluminum plant, the local weather conditions, and the location of the steam user. A corner of the factory area that can be in the downwind direction for a long time, and a side door is opened at this corner to facilitate the passage of coal vehicles to reduce the pollution of coal to the factory area environment. Then the boiler facility 1 is concentrated at one end of the factory area. The boiler facility 1 is composed of the first-phase boiler facility 1-1, the second-phase boiler facility 1-2, the third-phase boiler facility 1-3 and the N-phase boiler facility 1-N; And the first-phase boiler facilities 1-1, the second-phase boiler facilities 1-2, the third-phase boiler facilities 13 and the N-phase boiler facilities 1-N are arr...

Abstract

The configuration method of boiler houses in alumina plant includes concentrating the boiler facilities in one end of the plant and arranged in one row, concentrating the coal supplying systems in the other end and arranged in one row, establishing one main coal conveying belt in the boiler facilities and the coal supplying systems, connecting the separated coal conveying belts in each boiler facility and each coal supplying system to the main coal conveying belt, and establishing one shared coal breaking station between the boiler facilities and the coal supplying systems. The present invention has reduced total production system area, reduced total road area, shortened pipeline, compact structure and other advantages.

Description

technical field [0001] The invention relates to a configuration method for the serial layout of boiler rooms in an alumina plant, and belongs to the technical field of configuration of boiler facilities 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. In the production process of the alumina plant, the hot steam is generally generated through the boiler room for use in the evaporation, dissolution and other sections of the factory. The boiler room production system is generally composed of coal storage, coal conveyor belt, crushing station, boiler facilities and other auxiliary workshops. The existing boiler rooms are not well laid out. The boiler rooms are scattered and arra...
