Problems solved by technology

[0003] The existing dosing of chemicals adopts gravity dosing and pressure dosing. No matter which dosing method, from the dissolution pool to the solution pool, to the dosing point of the dosing liquid, the liquid medicine lifting equipment should be installed. The existing polyacrylamide The solution is put in by stirring and mixing, the mixing effect is poor, and the flocculation state of the subsequent sewage treatment is not good, which will cause a lot of waste of chemicals, and the injection is uneven. In many sewage treatment, the contact time of the solution is not equal, resulting in partial flocculation. , a partially incompletely processed state appears

Embodiment 1

[0024] refer to Figure 1-3 , a polyacrylamide solution spraying device for sewage treatment, comprising an electric sliding rail 1, the top inner wall of the electric sliding rail 1 is slidably connected with a liquid tank 7, and the top outer wall of the liquid tank 7 is provided with a feeding bin 6 in the middle, and the feeding bin 6 The outer wall of the bottom end is connected with the mixing bin 4 through a pipeline, the top outer wall of the liquid tank 7 is fixedly connected with a booster pump 5, and the output end of the booster pump 5 is connected to the outer wall of one side of the mixing bin 4 through a pipeline. The input end of the pressure pump 5 is connected with the liquid tank 7 through the pipeline, the bottom end outer wall of the mixing chamber 4 is fixedly connected with the liquid spray plate 3, and the outer wall of the liquid tank 7 away from the booster pump 5 is fixedly connected with a flow control valve 8, And the inner wall of the other end of...

Embodiment 2

[0027] refer to Figure 4 , a polyacrylamide solution spraying device for sewage treatment. Compared with Embodiment 1, the main difference between this embodiment is that in this embodiment, it also includes an ejector 16 and an air pump 17. The output end of the air pump 17 is connected to the ejector through an air pipe. 16 , the other end of the air pump 17 is fixedly connected with an air tank, and the end of the ejector 16 is connected to the bottom outer wall of the mixing chamber 4 .

[0028] The working principle of this embodiment: Based on the first embodiment, the liquid spray plate 3 is replaced with the injector 16, and the gas is pumped into the injector 16 through the air pump 17 for injection and injection, so as to improve the dosing effect of the polyacrylamide solution. .

Abstract

The invention discloses a polyacrylamide solution spraying device for sewage treatment, which comprises an electric slide rail, a liquid tank is slidably connected to the top inner wall of the electric slide rail, and a feeding bin is arranged in the middle of the top outer wall of the liquid tank. The outer wall of the bottom end of the bin is connected to a mixing bin through a pipeline, and a booster pump is fixedly connected to one side of the top outer wall of the liquid tank, and the output end of the booster pump is connected to one side of the outer wall of the mixing bin through a pipeline. The input end of the pressure pump is connected with the liquid tank through a pipe, and the outer wall of the bottom end of the mixing chamber is fixedly connected with a liquid spraying plate. The invention adopts a movable swinging spraying structure, which can be moved and sprayed onto the water surface in a linear shape, so that the solution can evenly and fully contact the upper part of the sewage water surface. , play a supplementary role, improve the mixing ratio of solution and sewage, and ensure the effect of polyacrylamide solution delivery.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a polyacrylamide solution spraying device for sewage treatment. Background technique [0002] The application of PAM in the water treatment industry mainly includes three aspects: raw water treatment, sewage treatment and industrial water treatment. In raw water treatment, PAM is used in conjunction with activated carbon, etc., and can be used for the coagulation and clarification of suspended particles in domestic water; in sewage treatment, PAM can be used for sludge dewatering; in industrial water treatment, it is mainly used as a formula agent. In raw water treatment, the organic flocculant PAM is used instead of inorganic flocculants, and the water purification capacity can be increased by more than 20% even if the sedimentation tank is not modified. Large and medium cities use PAM as a supplement when water supply is tight or water quality is poor. In sewage trea...
