Novel precipitation tower

Abstract

The invention relates to a novel precipitation tower. The novel precipitation tower comprises a cylinder body, a reverse cone, a cone, a buffer cone, a water inlet tube, an overflow tube, a clear water reuse tube, an accepted stock recovery tube, a sewage discharge tube and a support for supporting the cylinder body, the lower end of the cylinder body is connected with the upper end of the inverse cone, the bottom of the inner cavity of the cylinder body is provided with a supporting plate, one end of the water inlet tube is connected with the upper end of the cone, and the other end of the water inlet tube traverses through an upper end plate and stretches out to a position above the cylinder body; and the middle portion of the conical inner cavity of the cone is provided with a crossed supporting platform, and the buffer cone is arranged on the crossed supporting platform and is positioned in the conical inner cavity of the cone. The novel precipitation tower has the advantages of reasonable design, simple structure, stable running, easy processing, small size, use convenience, long life, energy saving, environmental protection, dispersion steady flow and buffer steady flow links, effective separation and recovery of fine fibers in a papermaking waste liquid, improvement of the utilization rate of the fine fibers, and recycling of separated water in a papermaking production line.

Description

technical field [0001] The invention relates to a novel sedimentation tower. Background technique [0002] With the improvement of people's living standards in our country, the demand for paper has increased greatly, and small paper mills have also sprung up all over the country. [0003] In the existing papermaking technology, there is a kind of waste liquid discharged from the papermaking factory called papermaking white water. The white water has a lot of fiber loss and cannot be used directly. The discharge will cause great pollution to the environment, and a large amount of fine fibers and waste water cannot be recycled. Reuse causes great waste, and companies invest a lot of money in wastewater treatment every year, but with little effect, causing a great economic burden to the company. This makes recycling very necessary. Contents of the invention [0004] The purpose of this invention is to provide a novel settling tower to solve the above-mentioned problems exis...
