Abstract

The invention provides a chemical spraying device for sewage treatment. The device comprises a sewage pipe provided with a jet device, chemical spraying pipes provided with superchargers and aerationpipes, wherein the jet device is mounted at the front end of the sewage pipe, the chemical spraying pipes are connected to side walls of two sides of the sewage pipe, the aeration pipes are connectedto the top side wall of the sewage pipe, the connection positions of the chemical spraying pipes and the sewage pipe are located at the front end of the connection positions of the aeration pipes andthe sewage pipe, and the included angle beta between the chemical spraying directions of the chemical spraying pipes and the flowing direction of sewage in the sewage pipe is an acute angle. Sewage and an injection agent are mixed through convergence of the high-speed flowing sewage and a high-speed sprayed injection agent, the high-speed flowing sewage produces negative pressure to increase the spraying speed of the injection agent, accordingly, the mixing effect of the sewage and the injection agent is enhanced, on the other hand, the injection agent is injected into sewage at a high speed,the flowing speed of the sewage is further increased, so that the negative pressure of the sewage when the sewage passes through the chemical spraying pipe and the aeration pipe is higher, and the following chemical spraying mixing and aeration effects are improved.

Description

technical field

[0001] The invention relates to the technical field of sewage treatment, in particular to a chemical spraying device for sewage treatment. Background technique

[0002] In recent years, people have paid more and more attention to fresh water pollution. Due to the direct pollution of drinkable fresh water by the development of industry, the storage of fresh water resources has become less and less. Therefore, the use of sewage treatment devices has become the choice of more people. At present, most of the sewage treatment is to fully stir and mix the sewage added with the injection agent, and then discharge it into the aeration tank for long-term aeration and sedimentation to achieve the purification effect. However, the purification steps in this way are cumbersome, the purification efficiency is low, and the equipment used takes up a lot of space.

[0003] Aiming at the problems of cumbersome sewage treatment steps, low purification efficiency and large spac...

Embodiment

[0022] like figure 1 As shown, the present embodiment provides a spraying device for sewage treatment, which device includes: a sewage pipe 10 provided with a jet 11, a spray pipe with a supercharger 20 installed, and an aeration pipe 30; the jet 11 is installed at the front end of the sewage pipe 10, the spraying pipe is connected to the side walls on both sides of the sewage pipe 10, the aeration pipe 30 is connected to the top side wall of the sewage pipe 10, and the spraying pipe The connection between the pipe and the sewage pipe 10 is located at the front end of the connection between the aeration pipe 30 and the sewage pipe 10, and the sewage in the sewage pipe 10 passes through the aeration pipe at high speed after being jetted by the jet device 11. The pipe 30 generates negative pressure, sucks the air from the aeration pipe 30 into the sewage pipe 10 and mixes it with the sewage to realize the aeration of the sewage. Such a device can realize the aeration of the sewa...
