Foam generating device used for dust fall

Abstract

The invention discloses a foam generating device used for dust fall. The foam generating device comprises an air inlet main pipe, one end of the air inlet main pipe is communicated with a foaming shell through a Venturi diffusion mechanism, the other end of the foaming shell is communicated with a foam output pipe, a longitudinal hollow air supply rod is arranged in the foaming shell, the air supply rod is sequentially provided with rotary power blades and a net type swirler, the air supply rod is provided with multiple air supply rod air outlet pipes which are evenly distributed in the circumferential direction of the air supply rod, an air supply rod air outlet is formed in the end, close to the foam output pipe, of the air supply rod and is of a horn mouth shape, the air supply rod air outlet corresponds to the foam output pipe, and an air supply rod air inlet pipe is arranged on the air supply rod and is communicated with the air supply rod air outlet and the air supply rod air outlet pipes. Foaming is performed on a foam dedusting agent solution three times, the foaming rate is greatly increased, and operation stability of the foam generating device is improved.

Description

technical field [0001] The invention relates to a foam generating device, in particular to a foam generating device for dust reduction. Background technique [0002] In recent years, with the increasing degree of mechanization, more and more industries, such as: coal mines, gold mines, wood processing and other industries, will produce high-concentration dust hazards in the production process, which is becoming more and more serious. First of all, high-concentration dust will increase the wear and tear of mechanical equipment in the workplace, reduce the service life of equipment, and increase operating costs. Secondly, high concentration of dust may cause dust explosion in the workplace, posing a threat to the safety of workers. Again, high concentrations of dust can also cause pneumoconiosis, endangering the health of workers on the job site. Therefore, the problem of high concentration dust has become an urgent problem to be solved in many industries. [0003] At prese...

AI Technical Summary

Problems solved by technology

At present, the commonly used foam generating devices at home and abroad mainly have two structures: net type and turbulence type. It is difficult to ensure that the foaming liquid is evenly dispersed on the net surface in the actual implementation of the net type foamer. At the same time, the foam is affected by the wind flow. Easy to deform, very poor foam stability and prone to insufficient power are rarely used

However, the current turbulent foam generating devices generally have problems such as poor stability, large energy loss, and difficult maintenance, which greatly reduces the practicability of this type of foam generating device
