A curtain spray atomizing dust suppressor

Abstract

An atomizing dust suppressor for curtain spraying, comprising a plate-shaped box, a chamber is provided in the box, and the chamber includes a nozzle chamber, a gap chamber and a slit chamber, and the nozzle chamber communicates with the gap chamber, The gap chamber communicates with the slit-shaped chamber, the bottom of the slit-shaped chamber is a spray slit, the first large side wall of the box body is provided with several water jet nozzles, and the second large side wall of the box body corresponds to each water jet nozzle Install the jet striker. The advantages of the present invention are as follows: 1. A dense water mist curtain can be sprayed to form a dust-reducing and dust-proof barrier. The curtain-like water mist disturbs less surroundings and improves the effect of isolating dust from spreading; 2. The atomizing dust suppressor uses high pressure The strong convective impact of water vapor in a limited space forms water mist and sprays out without using atomizing nozzles, eliminating the disadvantages of easy blockage of atomizing nozzles; 3. The structure is simple, the chamber is composed of side walls, easy to process, easy to maintain, and easy to use Low cost; 4. The water vapor pressure and flow can be adjusted according to the dust characteristics, so as to adjust the atomization effect.

Description

technical field [0001] The invention relates to a dust removal device, in particular to an atomizing dust suppressor for curtain spraying. Background technique [0002] With the increasingly stringent environmental protection requirements, the application of micron-level spray dust suppression technology has become more and more extensive, and spray dust suppression has obvious effects on the control of fine dust. At present, most of the spray dust suppression devices used are atomizing nozzles to create fog or slot spray devices with complex chamber structures. In actual use, problems such as nozzle blockage and unstable spray effect are very likely to occur, resulting in a short service life of the spray dust removal device, especially when the water quality is poor or the liquid viscosity is high. In addition, the water mist is sprayed from the atomizing nozzle, and the water mist is in a conical scattering state. When the dust suppression site is long and thin, the coni...

AI Technical Summary

Problems solved by technology

In actual use, the problems of nozzle clogging and unstable spray effect are prone to occur, resulting in a short service life of the spray dust removal device, especially when the water quality is poor or the liquid viscosity is high.

In addition, the water mist is sprayed from the atomizing nozzle, and the water mist is in a conical scattering state. When the dust suppression site is long and thin, the conical scattered mist sprayed by the nozzle will interfere with each other and disturb the water mist. Nearby airflow, causing dust to escape, reducing the effect of isolating dust from spreading

The slot-type spray device with a complex chamber structure has a complex structure, requires high machining accuracy, is difficult to maintain, and has high operating and maintenance costs.
