Description

Technical Field

[0001] The utility model relates to the field of dust removal, and specifically relates to a U-shaped tube dust removal device. Background Art

[0002] Exhaust gas often contains a variety of harmful substances, such as particulate matter, sulfur dioxide, nitrogen oxides, volatile organic compounds, etc. The accumulation of these substances in the atmosphere will cause serious pollution to the environment.

[0003] Current waste gas treatment methods mainly include physical adsorption, chemical absorption, catalytic oxidation, etc. These methods can remove harmful substances in waste gas to a certain extent, but often have problems such as low treatment efficiency, high energy consumption, and complex equipment. Especially for tiny particles in waste gas, current treatment methods often cannot achieve ideal dust removal effects. Utility Model Content

[0004] In order to overcome the above-mentioned deficiencies, the utility model provides a U-shaped tube dust removal device.

[0005] The technical solution adopted by this utility model:

[0006] A U-shaped tube dust removal device comprises a plurality of U-shaped tubes, which are arranged in sequence on the left and right, and are fixedly connected in sequence. The bottom of the U-shaped tube is fixedly connected to a liquid discharge pipe, and the tops of the two connected U-shaped tubes are fixedly connected to a liquid inlet pipe. Both the liquid inlet pipe and the liquid discharge pipe are equipped with valves. The left end of the leftmost U-shaped tube is fixedly connected to an air inlet pipe, and the right end of the air inlet pipe extends to the inner bottom of the leftmost U-shaped tube. The right end of the rightmost U-shaped tube is fixedly connected to an air outlet pipe, and the right end of the air outlet pipe has a fan. The air inlet end of the fan is fixedly connected to the right end of the air outlet pipe, and the air outlet end of the fan is fixedly connected to an exhaust pipe. The inner bottom of the U-shaped tube is a purifier, and the right end bottom of the air inlet pipe is inside the purifier.

[0007] Beneficial effects of the utility model:

[0008] The utility model adopts the design of multi-stage U-shaped tubes, so that the waste gas can contact the reaction liquid for multiple times, undergoing sufficient chemical reaction and dust removal treatment, thereby greatly improving the efficiency of dust removal and purification.

[0009] By adjusting the type and concentration of the reaction solution, it can adapt to the treatment needs of waste gas of different types and concentrations, and has strong adaptability and flexibility. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] like Figure 1-3 As shown: A U-shaped tube dust removal device, comprising a plurality of U-shaped tubes 1, the U-shaped tubes 1 are arranged in sequence on the left and right, the U-shaped tubes 1 are fixedly connected in sequence, the bottom of the U-shaped tube 1 is fixedly connected with a drain pipe 2, the tops of the two connected U-shaped tubes 1 are fixedly connected with a liquid inlet pipe 3, both the liquid inlet pipe 3 and the drain pipe 2 are equipped with valves, the left end of the leftmost U-shaped tube 1 is fixedly connected with an air inlet pipe 4, the right end of the air inlet pipe 4 extends to the inner bottom of the leftmost U-shaped tube 1, the right end of the rightmost U-shaped tube 1 is fixedly connected with an air outlet pipe 5, the right end of the air outlet pipe 5 has a fan 6, the air inlet end of the fan 6 is fixedly connected to the right end of the air outlet pipe 5, the air outlet end of the fan 6 is fixedly connected with an exhaust pipe 7, the internal bottom of the U-shaped tube 1 is a purifier 8, and the right end bottom of the air inlet pipe 4 is inside the purifier 8.

[0015] An appropriate amount of reaction liquid is injected into the U-shaped tube 1 through the liquid inlet pipe 3, and the exhaust gas is introduced into the system through the air inlet pipe 4 connected to the left end of the leftmost U-shaped tube 1. The right end of the air inlet pipe 4 extends to the inner bottom of the U-shaped tube 1, so that the exhaust gas can directly contact the reaction liquid at the bottom of the U-shaped tube 1, increasing the contact area between the exhaust gas and the liquid and improving the reaction efficiency.

[0016] The exhaust gas reacts chemically with the pre-added reaction liquid in the U-shaped tube 1. These reaction liquids usually contain components that can react chemically with harmful substances in the exhaust gas, thereby converting them into harmless or low-harmful substances. At the same time, when the dust particles in the exhaust gas pass through the U-shaped tube 1, they are effectively captured and retained in the liquid due to mechanisms such as inertial collision, gravity sedimentation or liquid adsorption, thereby achieving a dust removal effect.

[0017] The exhaust gas passes through a plurality of U-shaped tubes 1 arranged in sequence, and undergoes a chemical reaction and dust removal process each time it passes through a U-shaped tube. This multi-stage purification design greatly improves the exhaust gas treatment efficiency and dust removal effect, ensuring that the exhaust gas finally discharged meets national or local environmental protection standards.

[0018] The exhaust gas treated by the multi-stage U-shaped tube 1 is discharged through the outlet pipe 5 connected to the right end of the rightmost U-shaped tube 1. The outlet pipe 5 is connected to the air inlet end of the fan 6. The fan 6 provides power to discharge the treated exhaust gas into the atmosphere through the exhaust pipe 7.

[0019] When the reaction liquid needs to be replaced, the liquid can be discharged by opening the valve of the discharge pipe 2, and then new reaction liquid is injected through the liquid inlet pipe 3. This utility model only protects the mechanical part, and the functions realized by the software control part are not within the scope of protection of this utility model.
