Description

Technical Field

[0001] The utility model relates to the technical field of venturi scrubbers, in particular to a venturi scrubber with a fixed throat pipe and adjustable flow rate. Background Art

[0002] The dust removal of the Venturi scrubber includes three processes: atomization, condensation and dehydration. The first two processes are carried out in the Venturi tube, and the latter process is carried out in the cyclone separator. The dust-laden gas enters the air inlet pipe, and the air velocity gradually increases. The pressure of the air flow gradually turns into kinetic energy, and when it enters the throat, the flow velocity reaches the maximum value. Water enters through a number of small holes evenly distributed around the throat, and then is highly atomized under the impact of high-speed air flow. The high speed and low pressure at the throat make the air flow reach a saturated state. The air film attached to the surface of the same dust particle is broken, so that the dust particle is wetted by water. Therefore, fierce collision and condensation occur between the dust particle and the water droplet or dust particle. After entering the diffuser, the air flow velocity decreases, the static pressure rises, and the condensation action with the dust particle as the condensation nucleus accelerates. The dust removal efficiency is also related to the water vapor ratio. The appropriate water vapor ratio should be maintained during operation to ensure high dust removal efficiency.

[0003] At present, most of the Venturi scrubbers used are used in a single working condition. During on-site operation, the working flow fluctuates and cannot play a regulatory role. For this reason, we have designed a fixed throat Venturi scrubber with adjustable flow to solve the above problems. Summary of the invention
