Problems solved by technology

This method requires a lot of investment and energy consumption, and the treatment cost is high. The treated sediment can only be discharged as waste, wasting recyclable fibers; and its biochemical treatment of white water requires a large area and high power consumption. Pressure on production costs

Abstract

The invention discloses a compound white water filter, which comprises a cylinder body supported by feet, an inner filter screen and an outer filter screen which are arranged inside the cylinder body in sequence from the inside to the outside and are both coaxial with the cylinder body, and "T "shaped feed pipe; the end of the vertical pipe of the "T" shaped feed pipe is provided with a discharge port; the feed port of the "T" shaped feed pipe is equipped with a flow regulating mechanism, "T" The discharge port of the shaped feed pipe is provided with a disc distribution head, which is evenly distributed with several spray pipes forming the same angle with the radius of the inner filter screen; the "T" shaped feed pipe is installed There is a rotating mechanism connected with the inner filter screen as a whole, driven by the impact resultant force of the water flow sprayed by the injection pipe on the inner filter screen, and rotating around the vertical axis of the "T"-shaped feed pipe. The invention can effectively filter and recycle the fibers in the white water, reduce the discharge of solid matter, and increase the yield of raw materials; the filtered water obtained by the physical method can be used for ordinary low-pressure spraying, so as to save clean water.

Description

technical field [0001] The invention relates to the field of water treatment, in particular to a compound white water filter. Background technique [0002] In the paper industry, the water removed during web forming in the wet end of the paper machine, as well as the water removed further by vacuum boxes and presses, are collectively referred to as "white water". White water contains fibers, fillers and soluble paper-making chemicals. Separating these substances can be recycled, and the filtered water can be used for spraying operations on process points that do not require high water quality. It can be seen that white water treatment can greatly improve the yield of raw materials. efficiency, save costs, and reduce pollution. [0003] At present, the main methods of papermaking wastewater treatment at home and abroad are coagulation method and biochemical method. The equipment for treating papermaking wastewater by coagulation is mainly inclined plate sedimentation tank o...
