Embodiment 1

[0058] A device for treating yellow phosphorus sewage, such as figure 2 shown,

[0059] Including centrifugal sedimentation separator and liquid storage tank 12;

[0060] The centrifugal sedimentation separator includes a drum 1, and the drum 1 is a conical-cylindrical drum, such as figure 2 . The left end of the drum 1 is in the shape of a cone, and the right end is in the shape of a cylinder. The drum 1 is fixedly installed on the drum rotating shaft 2, and the two ends of the drum rotating shaft 2 are installed on the bearing seat outside the separator shell, and the drum rotates. The shaft 2 is located on the axis line of the drum 1 , and the drum 1 rotates around the axis line of the drum rotating shaft 2 .

[0061] The right end of the rotating drum 1 is provided with a feeding port 5, which is used to pass yellow phosphorus sewage into the rotating drum 1; the feeding port 5 is located on the rotating shaft 2 of the rotating drum, so that the rotation of the rotati...

Embodiment 2

[0072] A device for treating yellow phosphorus sewage, such as image 3 shown,

[0073] It includes a centrifugal sedimentation separator and a liquid storage tank 12; the centrifugal sedimentation separator includes a separator shell liquid outlet 13, and the separator shell liquid outlet 13 is located at the upper end of the liquid storage tank 12;

[0074] The centrifugal sedimentation separator includes a drum 1, and the drum 1 is a conical-cylindrical drum, such as image 3 , the left end of the drum is in the shape of a cone, and the right end is in the shape of a cylinder. On the line, the drum 1 rotates around the axis line of the drum rotating shaft 2 .

[0075] One end of the rotating drum 1 is provided with a feeding port 5, which is used to introduce yellow phosphorus sewage into the rotating drum 1; the feeding port 5 is located on the rotating shaft 2 of the rotating drum, so that the rotating drum 1 will not drive the feeding The material port 5 shakes up and...

Embodiment 3

[0084] The process flow of the yellow phosphorus sewage treatment method of the present embodiment is as follows figure 1 shown, figure 1 The separation device in is the device for the treatment of yellow phosphorus sewage in Example 1, such as figure 2 shown.

[0085] The yellow phosphorus sewage treatment process of the present embodiment includes:

[0086] The yellow phosphorus sewage from the phosphorus receiving tank and the delicate pot contains yellow phosphorus, water and dust. The dust wraps or adsorbs the yellow phosphorus. The yellow phosphorus sewage goes to the centrifugal sedimentation separator for centrifugal separation. After separation, solid phosphorus slag and liquid yellow phosphorus are obtained. and water; the liquid containing liquid yellow phosphorus and water goes to the liquid storage tank to stand for stratification, and after separation, yellow phosphorus and de-slag water are obtained. The specific operation steps are as follows:

[0087] Bef...

Abstract

The invention discloses a yellow phosphorus sewage treatment method and a yellow phosphorus sewage treatment device, belonging to the technical field of a chemical engineering technology and chemical equipment. The yellow phosphorus sewage treatment method comprises the following steps: adjusting the temperature of yellow phosphorus sewage to be 60-80 DEG C; separating dust in the yellow phosphorus sewage from yellow phosphorus and water to obtain phosphorus dreg and liquid containing the liquid yellow phosphorus and the water; and standing and layering the liquid yellow phosphorus and the water to obtain dreg-removed water and yellow phosphorus. According to the yellow phosphorus sewage treatment method, the time for treating the yellow phosphorus sewage is short and the efficiency is high; the content of the phosphorus in the treated phosphorus dreg is low and the waste of phosphorus resources is reduced; the pollution to the environment by the yellow phosphorus sewage is alleviated.

Description

technical field [0001] The invention relates to a sewage treatment method and device, in particular to a yellow phosphorus sewage treatment method and device, belonging to the technical field of chemical technology and chemical machinery and equipment. Background technique [0002] Yellow phosphorus, also known as white phosphorus, is a white to light yellow brittle waxy solid with a melting point of 44.1°C, a boiling point of 280°C and a density of 1.82g / cm 3 . Yellow phosphorus is an extremely important basic industrial raw material and is used in many fields such as chemical industry and pesticide. At present, my country's total output ranks first in the world. There are hundreds of yellow phosphorus production plants, mainly located in Yunnan, Guizhou, Sichuan and Hunan provinces. The production capacity of yellow phosphorus in Yunnan, Guizhou and Sichuan exceeds 80% of the country. [0003] In the prior art, the method for producing yellow phosphorus mainly uses phosp...
