Abstract

The utility model relates to the field of sewage treatment by a mixer, in particular to a split flow static mixer, which mainly includes a flange, a bidirectional water inlet pipe, a mixer shell, a mixer unit body, a symmetrical split flow dosing pipe, and a main pipe. The unit body has a reverse helical structure and is fixed inside the mixer by welding. The symmetrical split-flow dosing pipe is inserted into the mixer shell in parallel and connected to the mixer shell through a flange. The outlet of the dosing pipe is split-flow, and the split-flow direction points to the water inlet. The two-way water inlet pipe is respectively connected to the main pipeline and the static mixer housing through flanges, which is convenient for disassembly. Sewage flows in from the main pipeline, diverts through the two-way water inlet pipe, and flows into the mixer. The medicine flows in from the dosing pipe, and flows into the mixer through the diversion method. The two liquids collide with each other, increasing the contact area and improving the uniformity of mixing. Flow through the reverse helical unit for further mixing. The utility model is beneficial to the full contact and mixing of sewage and medicine through the way of sewage and medicine diversion.

Description

A split static mixer

technical field

The utility model relates to the field of sewage treatment by a static mixer, in particular to a split static mixer. By diverting sewage and medicaments, the direction of the medicament shunt pipe is directed toward the water inlet, and the total amount of sewage is shunted through the water inlets on both sides, and respectively Mixing with medicaments increases the contact area between medicaments and sewage, improves the uniformity of mixing, reduces the water flow velocity, and increases the mixing time.

Background technique

Static mixer is a common mixing equipment, usually used in the sewage treatment industry, and the operating mechanism is different from the traditional agitator, it has no moving parts inside, mainly using fluid flow and internal units to achieve the mixing of various fluids, with Features of low shear force and fast mixing. Generally, static mixers mainly improve the mixing effect by improving the structure of the shell and the unit body. There are many types of structures, such as nozzle type, vortex type, cross plate type, spiral blade type, etc. It is more complicated to improve the structure of the shell and the unit body, especially for the unit body, due to the particularity of its structure, it is difficult to process, and it is often processed integrally with the shell. The dosing port mostly adopts single or multi-point dosing method for dosing, but for the dosing port, the single dosing method cannot effectively mix the medicine with the sewage, and the multi-point dosing method increases the process flow. Currently, for There are not many studies on the water inlet method of the mixer, especially for the static mixer with the split water inlet method.

Utility model content

Aiming at the above problems, the utility model provides a flow-distributing static mixer, which improves the mixing uniformity of sewage and medicament.

The utility model adopts the following technical solutions:

A split-flow static mixer mainly includes a flange, a two-way water inlet pipe, a mixer shell, a mixer unit body, a symmetrical split-flow medicine feeding pipe, and a main pipeline. The mixer unit has a reverse spiral structure and is welded inside the mixer shell. The two-way water inlet pipe is symmetrically arranged on both sides of the shell, one end is connected to the main pipeline through a flange, and the other end is connected to the mixer shell. connect.

The dosing pipe is inserted into the mixer housing in parallel and connected to the mixer housing through a flange.

There are two shunt pipes at the outlet of the dosing pipe. The medicine flows in from the dosing pipe and flows through the shunt pipe. The directions of the two shunt pipes point to the water inlet area respectively. Collision, accelerated mixing, due to the symmetrical inflow of sewage, itself will also accelerate the collision, and the water enters through the vertical direction, which reduces the speed of sewage inflow and prolongs the mixing time.

detailed description

Below in conjunction with accompanying drawing, the utility model is described in further detail:

A split static mixer, mainly including a flange (1), a two-way water inlet pipe (2), a mixer shell (3), a mixer unit (4), a symmetrical split feed pipe (5), a main pipe road (6). The symmetrical shunt dosing pipe (5) is welded with a flange (1), the dosing pipe is inserted into the mixer shell in parallel, and is connected with the mixer shell (3) through the flange (1), and the dosing pipe The outlet diversion direction corresponds to the direction of the water inlet pipe. The two-way water inlet pipe is respectively connected with the main pipe and the static mixer housing through the flange (1), which is convenient for disassembly. Sewage flows in from the main line (6), and then splits, and flows into the mixer through the two-way water inlet pipe (2). The flange (1) is convenient for connection with the chemical circuit, sewage circuit and static mixer, and the sewage flows into the mixer. At the same time inside the shell (3), the medicament flows in from the symmetrical shunt dosing pipe (5), and then through the shunt, it presents a symmetrical spray, and the direction is toward both sides of the water inlet. Mixing can make the medicine and sewage better contact, and the two fluids are fully mixed through the mixer unit (4), and finally flow out from the discharge port of the static mixer.
