1. Introduction to Horizontal Spray Cabinet
The principle of wet dust removal is a process of dust removal that utilizes sufficient contact between gas and liquid phases to capture and separate dust particles in the gas phase.
The commonly used structural forms currently include:
Storage type: filled with a certain amount of water, high-speed dusty gas impacts to form water droplets, water films, and bubbles, which wash the dusty gas, such as impulse dust collectors, water bath dust collectors, and horizontal cyclone water film dust collectors.
Pressurized water spray type: supply pressurized water to the dust remover, and use spray or spray to generate water droplets to wash the dusty gas, such as Venturi tube dust remover, foam dust remover, filler tower, turbulence tower, etc.
Forced rotating spray type: forced rotating spray by mechanical force, or rotating blades to form water drops, water films, bubbles, and wash dusty gas, such as rotating spray dust remover.

3.Working principle of horizontal spray cabinet
The horizontal spray cabinet is equipped with two water curtain plates inside, the first one is a stainless steel rectangular orifice plate, and the second one is a non perforated stainless steel plate; Water enters from the water injection tank above the water curtain plate, forming a layer of water film on the stainless steel plate that flows from top to bottom. The end of the exhaust gas dust collector enters and collides with the flowing water film from top to bottom, so that the dusty gas is wetted and intercepted by the water film, and the dust particles flow with the water to the water storage tray at the bottom of the dust collector. After colliding with the second water curtain plate, the exhaust gas impacts the circulating liquid level in the water collection tray along the bottom of the water curtain plate, and some coarse dust particles directly settle in the water collection tray. Subsequently, the dusty gas passes through the S-shaped channel at high speed, causing a large number of water droplets to fully contact and remove the dust content in the gas. This method has a removal efficiency of over 85% for particulate dust particles over 5m.
4.Characteristics of horizontal spray cabinet
After dust removal, the gas is separated by a gas water separator at the outlet to remove moisture from the gas; The flue gas passes through the curved channel of the defogger and separates the liquid droplets carried in the airflow under the action of inertia and gravity. After dust removal, the flue gas flows through the defogger at a certain speed, and the direction of movement of the flue gas is quickly and continuously changed. Due to the centrifugal force and inertia, the fog droplets in the flue gas collide with the defogger blades and are captured. The fog droplets gather and form a water flow. Due to the action of gravity, they fall into the bottom water tray, achieving gas-liquid separation, so that the flue gas flowing through the defogger meets the defogging requirements and is discharged.
Compared with vertical spray dust removal towers, horizontal spray (water curtain) dust removal cabinets have the advantages of convenient maintenance and diverse dust removal methods. This dust removal cabinet adopts water curtain and impulse vortex dust removal. The cabinet body is made of stainless steel material, and the water tray is made of stainless steel material. The inspection door is opened on the side of the cabinet for easy access and maintenance by personnel.
Advantages: Convenient layout, large purification and dust removal air volume, high dust removal efficiency, and easy maintenance.
