Description

Rural integrated ultrafiltration membrane water treatment device

technical field

The utility model relates to a rural integrated ultrafiltration membrane water treatment device, which belongs to the field of rural drinking water treatment equipment.

Background technique

The existing rural integrated ultrafiltration membrane water treatment device includes a mixing tank, an ultrafiltration membrane device and a clear water tank connected by secondary pipelines. Ultrafiltration membrane devices are prior art. Raw water is pumped into the mixing tank, then coagulant is added, and an agitator is installed in the mixing tank, and the coagulant and raw water are stirred evenly by the agitator, and then the medicine and water in the mixing tank are pumped to the ultrafiltration membrane device for treatment. Like this, agitator runs all the time, and energy consumption cost is high, and investment is big, and operating cost is high.

In order to solve the above problems, at present, some people use a tubular static coagulator to mix the coagulant and raw water. The tubular static coagulator generally includes an outer tube, and a spiral baffle is set inside the outer tube, the coagulant is added into the mixing tank, and the water and the coagulant pass through the tubular static coagulator together, so that the coagulant and water The mixture is evenly mixed, which reduces energy consumption. But its mixing uniformity is poor.

Utility model content

In view of the existing problems, the purpose of the utility model is to provide a rural integrated ultrafiltration membrane water treatment device with low energy consumption and uniform mixing of medicament and water.

In order to achieve the above object, the technical solution of the utility model is: a rural integrated ultrafiltration membrane water treatment device, including a mixing tank, an ultrafiltration membrane device and a clear water tank connected by pipelines in sequence, characterized in that: the mixing tank and A mixing diffuser is installed on the pipeline between the ultrafiltration membrane devices, and the mixing diffuser includes a box body, and a vertical orifice plate is arranged in the box body, and the box body is divided into a mixing chamber and a diffusion chamber by the orifice plate. The side wall of the chamber is provided with a drainage tube communicating with the mixing chamber, the outlet of the drainage tube is provided with a conical cap, the conical tip of the conical cap is facing the outlet of the drainage tube, and the diffusion chamber is provided with a diffuser The diffuser tube is composed of a first tapered section, a constant diameter section and a second tapered section in turn, and the small-diameter end of the first tapered section and the small-diameter end of the second tapered section are respectively connected to different The two ends of the variable-diameter section are connected, the large-diameter end of the first tapered section is connected to the orifice plate, and the large-diameter end of the second tapered section is connected with the outlet of the diffusion chamber; It is connected with the drainage pipe, and the outlet of the diffusion chamber is connected with the raw water inlet of the ultrafiltration membrane device through a pipeline.

Using the above scheme, the coagulant is added to the raw water in the mixing tank, and then flows to the mixing diffuser. The raw water enters the mixing chamber from the drainage tube, and the water flow from the drainage tube hits the conical cap, forming a violent turbulent flow, making the medicine Mix quickly with water. Then it flows through the orifice into the diffuser tube. After entering the diffuser pipe, it first enters the first conical section. Since the diameter of the first conical section is getting smaller and smaller, the flow velocity is increasing. When the water flow reaches the constant diameter section, the velocity reaches the maximum. Then it enters the second tapered segment with gradually larger diameter, and the flow velocity becomes slow. In the diffusion tube, due to the difference in flow velocity, the medicine and water are mixed more uniformly. Finally, the water flows out of the ultrafiltration membrane device from the outlet of the diffusion chamber, and enters the clear water pool after being treated by the ultrafiltration membrane module.

In the above solution: the drainage tube is arranged on the opposite side wall of the orifice plate, and the conical cap is fixed in front of the orifice plate through a bracket. Preferably, the drainage tube is located at the center of the side wall opposite to the orifice plate. The outlet of the diffusion chamber is located on the side wall opposite to the orifice plate. The central lines of the drainage tube, the conical cap, the diffusion tube and the outlet of the diffusion chamber are on the same straight line, which is convenient for design and processing.

In the above solution: the length of the second tapered section is greater than the length of the first tapered section. In this way, the raw water and the medicament can be fully mixed evenly in the second conical section.

The beneficial effects of the utility model are: the utility model is reasonable in design, simple in structure, less in equipment investment, and low in energy consumption. better.
