Water curtain type dust-free ash discharge device

Abstract

The invention discloses a water curtain type dust-free ash unloading device, which comprises a frame, an ash inlet located above the frame, and an ash unloading nozzle for outputting dust. The cylinder is connected with the ash inlet; under the frame, there is a ring-shaped water supply pipe located on the outside of the telescopic cylinder. The water inlet of the ring-shaped water supply pipe is equipped with an electric ball valve, and several high-pressure nozzles are evenly distributed on the ring-shaped water supply pipe. , the high-pressure nozzle sprays to form an annular water mist under the annular water supply pipe. In the present invention, the annular water mist sprayed by the high-pressure nozzle provided on the annular water supply pipe is used. The annular water mist is located around the ash discharge nozzle, which effectively avoids the secondary dust problem during the ash discharge process and solves the problem of the existing unloading device. The problem of secondary pollution is easy to occur; at the same time, the present invention realizes water mist dust suppression outside the equipment, effectively eliminating the dust compaction phenomenon inside the equipment, thereby eliminating the impact of the dust compaction phenomenon on the equipment.

Description

technical field [0001] The invention relates to a dust-free unloading device, in particular to a water curtain type dust-free ash unloading device. Background technique [0002] The dust-free ash unloading device supporting the bag filter used in metallurgy and other industries generally adopts a humidifier and a dry unloader. The following problems exist to varying degrees during use: [0003] 1) When a humidifier is used for ash unloading, the dedusting ash with poor wettability and strong compaction will form a hardening phenomenon inside the humidifier, resulting in heavy cleaning work for the humidifier. At the same time, the dust ash sticks to the impeller of the feeder, which will increase the load on the motor of the feeder and cause damage to the motor. [0004] 2) When a dry unloader is used for ash unloading, the secondary dust of the dry dust removal process is serious during the unloading process. [0005] Therefore, urgently need to solve the above-mentioned...
