A constant flow filtration device for centrifugal mother liquor water

Abstract

The invention provides a constant-flow filtration device for centrifugal mother liquor water, comprising a filtration pipe, an internal constant-current part and an external constant-current part; At the installation end of the internal constant current part, the top of the vertical part is connected with the middle part of the horizontal part, and the bottom end is the filter outlet end; the filter outlet end is equipped with a filter plate; the internal constant current part includes a support plate, an adjustment connecting rod and an internal constant current part. The flow plate; the external constant flow part includes an external constant flow tank, a constant flow regulating pump, a lead-out pipe at the filter inlet and an introduction pipe at the filter outlet. The invention provides a filtration device capable of adjusting the water flow rate of the centrifugal mother liquor, which can effectively ensure that the flow rate of the centrifugal mother liquor entering from the inlet end of the filtration and reaching the outlet end of the filtration for filtration is kept roughly constant, so as to maintain the filtration efficiency and filtration quality, and is the best solution for the centrifugal mother liquor. The filtration and recycling of mother liquor water provides convenience.

Description

technical field [0001] The invention belongs to the field of filtration equipment, and in particular relates to a constant-flow filtration device for centrifugal mother liquor water. Background technique [0002] When using the suspension method of polyvinyl chloride device for production, 1tPVC produces 3-4t centrifugal mother liquor water. Most enterprises discharge it directly after simple treatment. With the promotion of environmental protection concepts, some enterprises have begun to recycle and reuse the centrifugal mother liquor water. , First of all, it is necessary to filter the centrifugal mother liquid water. Generally, a simple filter plate is used for filtration. However, in the actual operation process, it is found that the flow rate of the centrifugal mother liquid water cannot be controlled. hours, the filtration efficiency is also relatively low, which affects the subsequent process steps. [0003] Therefore, in view of the above problems, developing a dev...

Problems solved by technology

[0002] When using the suspension polyvinyl chloride device for production, 1 ton of PVC produces 3 to 4 tons of centrifuged mother liquor water, and most enterprises discharge it directly after simple treatment. With the promotion of environmental protection concepts, some enterprises have begun to recycle the centrifuged mother liquor water. , first of all, it is necessary to filter the centrifuged mother liquid water. Simple filter plates are generally used for filtration. However, in the actual operation process, it is found that the flow rate of the centrifuged mother liquid water cannot be controlled. When the flow rate is too large, the filtration quality is low and the flow rate is too high. Hours, the filtration efficiency is relatively low, affecting the subsequent process steps
