烧结厂设计说明书

1 Introduction

1.1 Outline

The design reference Baosteel sintering plant, according to the design requirements of the mission statement, the design production capacity of 300 tons, the sintering plant products of high quality for blast furnace sinter.

Because annular cooler temperature exhaust gas discharged with the airflow and fine dust released into the air, allowing more serious environmental pollution, while a large number of hot exhaust gas into the atmosphere, waste heat, dust and heat in order to reduce emissions, reduce pollution of the environment, the design of the ring after a hot exhaust gas cooler dust stove and holding furnace used for point after.

The design of the sintering engineering technology, equipment level and the degree of automation and, basically, Baosteel sintering plant rather, is the world's advanced level, the design of a complete process: thick material layer sintering, centralized dust removal system, dual diagonal band spot stove, the addition of a ring cooler holding furnace and hot exhaust gas emissions as a promoter, these are the sintering process technology and equipment constitute the main content, but also an important indicator of the level of today's world.

1.2 Design basis and design principles

1.2.1 Design basis

This design is the Central South University of Resources Processing and Bioengineering pellets Professional 2013 session of the graduate design task, entitled "Design sinter plant of an annual output of 3 million tons of sinter" which combined in Baosteel graduation internship process field data collected and the master site processes and equipment prepared on the basis of.

1.2.1 Design principles

In order to do this sinter plant design, intended to the following design principles:

1) According to today's world sintering technology, combined with the actual situation of Baosteel, determine the design process technology and equipment level.

2) reasonably compact device configuration, production workshop has sufficient operating area to ensure smooth material transport facilities.

3) selection of equipment, construction to achieve standardization and universal.

4) Take effective measures to reduce the sinter plant dust pollution.

5) Consider the possibility of future expansion.

1.3 Design range

The design of the sintering project include the following:

1) coke crushing and screening system.

2) ingredients mixed system.

3) sintering and cooling system.

4) the main electrical room.

5) finished crushing and screening system.

6) the dust handling system.
