High-salt solid waste integrated washing equipment and control method thereof

Abstract

The invention provides high-salt solid waste integrated washing equipment and a control method thereof, the washing equipment comprises a three-stage filter which is vertically arranged, the position of a washing tank in a second-stage filter and the rotating direction of a ceramic plate are just opposite to those of a first-stage filter and the three-stage filter, and materials treated at all stages can be directly conveyed under the action of gravity; the configuration of related equipment in the material conveying process is greatly simplified; the washing tank and the vacuum ceramic filter are combined to form integrated washing and filtering equipment, and the washed materials are directly conveyed into the material tank of the filter under the extrusion action of the stirring paddle, so that the continuity of a washing and filtering working system is further enhanced; according to the control method, a double-factor adjustment mode is adopted, the influence of another parameter on the equipment operation effect in the single-factor adjustment process can be avoided, the control process is more comprehensive, and the equipment operation efficiency can be further improved.

Description

technical field [0001] The invention relates to iron ore sintering treatment equipment, in particular to a high-salt solid waste integrated water washing equipment and a control method thereof. Background technique [0002] Sintering head electrostatic precipitator ash is the dust collected by the sintering head flue gas electrostatic precipitator during the iron ore sintering process. It is a common high-salt solid waste in the iron and steel industry. Affected by a series of complex physical and chemical changes during the sintering process, the elemental composition of the sintering head ash contains not only impurity elements such as lead, potassium and sodium that are harmful to blast furnace ironmaking, but also a large amount of iron, carbon, silicon, and calcium. , aluminum and other elements useful for iron and steel smelting. In order to avoid the corresponding elements affecting the performance of the blast furnace or causing heavy metal pollution and waste of re...

Problems solved by technology

According to the actual use on site, it is found that due to the lack of integrity between the equipment at all levels, this method has obvious disadvantages such as large floor area, large equipment consumption, and difficult overall control.

[0004] At the same time, the existing equipment control method only controls a single vacuum ceramic filter, the control object is relatively single, the control is not precise, and the energy consumption is large. At the same time, the existing control scheme of the vacuum ceramic filter is mainly based on the method of single factor adjustment. Affect the operating efficiency of the equipment
