Bidirectional lateral washing method for filter cake of filter press

Abstract

The invention discloses a bidirectional lateral washing method for a filter cake of a filter press. A three-way left pipeline and a three-way right pipeline are arranged on the two sides of a thrust plate of the filter press to realize bidirectional lateral washing, wherein the three-way left pipeline is provided with a left valve and is connected with a washing pump; the three-way right pipeline is provided with a right valve and is connected with the washing pump; the three-way left pipeline is provided with a left drain valve and is connected with a drain pipe; the three-way right pipeline is provided with a right drain valve and is connected with the drain pipe; upper rinsing holes and lower rinsing holes are formed at four corners of a filter plate; an upper liquid inlet hole and a lower liquid inlet hole are formed on one side of the filter plate; one side of the filter plate is connected with a filter chamber; and the filter plate is installed on a main beam and is transversely arranged along lateral holes. When the filter cake is washed by the bidirectional lateral washing method for the filter cake of the filter press, beneficial effects are as follows: the purity of the filter cake is quickly improved, the recycling rate of filtrate is quickly improved, the energy is saved, the cost is reduced, and the production efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of filter press filtration. In more detail, it relates to a double-side washing method for filter cake of a filter press. Background technique [0002] After the filter press is filtered, the filter cake remains in the filter chamber. The filter cake washing is an important part of solid-liquid separation. The filter cake washing of the filter press has great economic significance. According to the requirements of the material filtration process, the filter press filter The filter cake needs to be washed with washing liquid. The purpose is to wash the liquid impurities in the filter cake with washing liquid, improve the purity of solid components in the filter cake, wash the filter cake with washing liquid to recover the valuable filtrate in the filter cake, and improve the quality of the filtrate. The recovery rate, the process layout and work efficiency of washing filter cake are completed by the filter p...

[0002] After the filter press is filtered, the filter cake remains in the filter chamber. The filter cake washing is an important part of solid-liquid separation. The filter cake washing of the filter press has great economic significance. According to the requirements of the material filtration process, the filter press filter The filter cake needs to be washed with washing liquid. The purpose is to wash the liquid impurities in the filter cake with washing liquid, improve the purity of solid components in the filter cake, wash the filter cake with washing liquid to recover the valuable filtrate in the filter cake, and improve the quality of the filtrate. The recovery rate, the process layout and work efficiency of washing filter cake are completed by the filter press. The key lies in the position of the filter plate washing holes configured by the filter press and the washing method of the pipeline layout. The washing method used is related to the filtration cost and production efficiency. At present, the filter cake washing method used in the filtration industry is still the traditional washing method, the washing liquid consumption is large, the washing cycle time is long, the process is cumbersome, the washing process is slow, the washing liquid pressure is low and the flow rate is small, waste of energy, high production cost, and affect the filtration efficiency
