Atomizing dust-settling device capable of spraying in curtain shape

Abstract

The invention discloses an atomizing dust settling device capable of spraying in curtain shape. The atomizing dust settling device comprises a plate-shaped box body, a cavity is formed in the box body and comprises a spray head cavity, a gap cavity and a seam-shaped cavity, the spray head cavity communicates with the gap cavity, the gap cavity communicates with the seam-shaped cavity, the bottom face of the seam-shaped cavity is a spray narrow opening, a plurality of water jet nozzles are arranged on the side wall of a first large face of the box body, and jet flow strikers corresponding to the water jet nozzles are installed on the second large face side wall of the box body. The atomizing dust settling device has the following advantages that 1, a dense water mist curtain can be sprayed out to form a dust falling and isolating barrier, the disturbance of curtain-shaped water mist to the surroundings is less, and the effect of isolating dust from spreading is improved; 2, the atomizing dust-settling device forms water mist to be sprayed out by utilizing high convection impact of high-pressure steam in a limited space, and an atomization spray head is not used, so that the defect that the atomization spray head is prone to being blocked is eliminated; 3, the structure is simple, the cavity is composed of the side walls, machining is easy, maintenance is convenient, and the use cost is low; and 4, the water vapor pressure and flow can be adjusted according to the dust characteristics, so that the atomization effect is adjusted.

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.
