Description

Efficient Turbulent Ejector

technical field

The utility model relates to a high-efficiency turbulent jet.

Background technique

At present, ejectors are commonly used in the aeration process of sewage treatment. Conventional ejectors are prone to clogging during use, and the discharge of waste gas and waste water is large, and the transfer rate of oxygen is not high, which affects its aeration effect.

Contents of the invention

The purpose of this utility model is to solve the problems that the current jet device cannot be easily blocked, the discharge of waste gas and waste water is large, the transfer rate of oxygen is not high, which affects its aeration effect, and provides a simple structure, easy to use, It is a high-efficiency turbulent jet with many advantages such as significant energy saving, no clogging, uniform aeration, and good stirring effect.

In order to achieve the above object, the utility model adopts the following technical solutions:

A high-efficiency turbulent jet, which includes a three-way jet body cast in one piece, one side is a water outlet pipe, the other side is a water inlet pipe, and the two are connected to an air inlet pipe; the water outlet pipe is a water-gas mixed The cavity is provided with a wire on the inner wall of the water outlet pipe.

A reinforcing rib is provided between the air inlet pipe, the water outlet pipe and the water inlet pipe, and a flange is arranged at the mouth of the air inlet pipe.

The water inlet is also provided with a flange.

The wooden utility model adopts the casting method and is formed at one time; in order to make the fluid fully contact with the oxygen in the air, a special curved structure is set in the outlet pipe cavity to keep the fluid in a turbulent state all the time.

The beneficial effects of the utility model are:

1. High utilization rate of oxygen: the small air bubbles in the air have high diffusion efficiency in the high-speed fluid, and the turbulent flow state of the fluid in the inner chamber of the ejector is constantly updating the gas-liquid contact surface, which is also conducive to the transfer and absorption of oxygen.

2. Good process applicability: the ejector has many advantages such as significant energy saving, no clogging, uniform aeration, and good stirring effect. The system consists of a circulating water pump and a fan. The circulating water pump is used to circulate the liquid in the pool. The liquid enters the ejector to be pressurized, and then enters the reaction pool after fully contacting with the low-pressure air. The cost of aerobic treatment of wastewater mainly comes from the electricity consumption of aeration, and the electricity consumption of aeration depends on how much oxygen is absorbed into the water. This product increases the transfer rate of oxygen, so it saves electricity and energy.

3. Reduce exhaust gas emission and water mist generation: the ordinary aeration process is easy to generate exhaust gas and water mist due to the low utilization rate of oxygen, and the jet device has a high oxygen utilization rate due to the full contact between air and fluid, and therefore It produces less water mist and waste gas, and there is no need to invest in waste gas collection and treatment equipment in the project.

4. Convenient maintenance: This product is cast and formed, connected to the pipeline with flanges, easy to disassemble, because the cavity is filled with high-speed fluid and gas, so it is not easy to block, and it is suitable for self-backwashing.

5. Economic performance: This product is cast and formed, and conventional mechanical processing equipment can be used, with less investment, and can be ordered according to the project without any risk.
