Embodiment 1

[0030] This embodiment provides a novel gas lift device, such as figure 1 As shown, the novel gas lift device includes a gas delivery pipe 2, a gas lift pipe 1, a liquid inlet pipe 3 and a friction member, the gas lift pipe 1 is in an inverted L shape, and the liquid inlet pipe 3 is connected to the gas lift pipe 1, the gas inlet of the gas delivery pipe 2 is used to charge gas, and the gas outlet is fluidly connected to the bottom of the stripping pipe 1 and is located above the liquid inlet pipe 3, and the friction member includes A plurality of friction protrusions 4 are evenly arranged on the inner wall of the stripping tube 1 .

[0031] The novel gas lift device of this embodiment utilizes the density difference of the liquid inside and outside the gas lift tube to lift the liquid. Specifically, when in use, the liquid inlet pipe 3 can be placed in the place where the carriers in the biochemical tank of the MBBR sewage treatment system are densely packed, and high-pressu...

Embodiment 2

[0034] Novel gas stripping device as described in embodiment 1, such as figure 1 As shown, the liquid inlet pipe 3 is trumpet-shaped, and the smaller end of the trumpet-shaped liquid inlet pipe 3 is connected to the stripping pipe 1;

[0035] The trumpet-shaped liquid inlet pipe 3 is integrally formed with the stripping pipe 1 .

[0036] The liquid inlet pipe 3 is in the shape of a trumpet, so that the compressed air and other gases transported here through the gas delivery pipe 2 can be quickly discharged into the liquid, and the gas-liquid mixture can also enter the stripping pipe 1 through the liquid inlet pipe 3 more quickly and start to be vaporized. to another location.

Embodiment 3

[0038] Novel gas stripping device as described in embodiment 1, such as Figure 2-4 As shown, the friction protrusions 4 are in the shape of water droplets and have a smooth surface. A plurality of friction protrusions 4 are arranged in parallel, and each water drop-shaped friction protrusion 4 is arranged with its tip pointing upward.

[0039] According to the Venturi theory, in this embodiment, the friction protrusion is designed as a three-dimensional polyhedral drop shape, which will generate a pressure difference when water and air flow, increase the disturbance of the water flow, and increase the contact and collision probability between the carrier and the friction protrusion in the water flow. At the same time, the air in the water flow is cut into fine bubbles, which can promote the dissolution of oxygen in water, provide more dissolved oxygen for the biofilm on the carrier, and a higher concentration of dissolved oxygen can promote the activity of microorganisms on th...

Abstract

The invention provides a novel gas stripping device. The novel gas stripping device comprises a gas conveying pipe, a gas stripping pipe, a liquid inlet pipe and a friction piece, wherein the gas stripping pipe is in a toppled L shape, the liquid inlet pipe is connected to the bottom end of the gas stripping pipe, a gas inlet of the gas conveying pipe is used for being filled with gas, a gas outlet of the gas conveying pipe is connected to the bottom of the gas stripping pipe in a fluid communication mode and located above the liquid inlet pipe, and the friction piece comprises a plurality offriction protrusions evenly distributed on the inner wall of the gas stripping pipe. According to the novel gas stripping device disclosed by the invention, the plurality of friction protrusions are arranged on the inner wall of the gas stripping pipe, the lifting device is used for lifting liquid in a biochemical pool in the MBBR sewage treatment system, when the gas-liquid mixture is lifted to other areas through the gas stripping pipe, the carrier in the liquid is in collision contact with the friction protrusions, and a low-activity thick biological membrane on the carrier falls off, so that the frequency of updating the biological membrane on the carrier is effectively increased, the biological membrane on the carrier is always in a high-activity state, and a better sewage treatment effect is achieved.

Description

technical field [0001] The invention relates to the technical field of sewage gas lift, in particular to a novel gas lift device. Background technique [0002] With the development of the economy, environmental problems have become increasingly prominent, and the country has paid more and more attention to environmental protection issues. At present, the state requires that sewage treatment plants raise the discharge standards of treated sewage. Many sewage treatment plants have been built for a long time, the secondary process of sewage treatment is backward, the volume load is low, the floor area is large, and the total nitrogen discharge exceeds the standard. Upgrading to the secondary treatment process. The process transformation should be carried out in accordance with the principle of meeting the standard discharge and reducing the comprehensive cost of sewage treatment as much as possible. On the premise of not occupying new land and building new structures, the bioc...
