In the above-mentioned face formula high efficiency that aims at acid gas removes centrifugal fan, an air inlet section of thick bamboo is kept away from main part one end opening part fixedly connected with filter screen.
In the above-mentioned high-efficient centrifugal fan that removes of face formula to acid gas, air inlet cylinder inside wall is equipped with the recess, the connecting roll rotates to be connected in the recess inside wall.
In foretell face formula high efficiency to acid gas removes centrifugal fan, clean mechanism includes the reaction box, bottom surface under the reaction box fixed connection air inlet section of thick bamboo, the reaction box both sides all are equipped with the opening, the filter cloth runs through the reaction box through two openings, the reaction box intussuseption is filled with a large amount of alkaline solution.
In the above surface-type efficient centrifugal ventilator for removing and purifying acidic gas, two fixing rods are arranged in the reaction box, and the filter cloth is sleeved outside the two fixing rods.
In foretell high-efficient centrifugal fan that removes of face formula to acid gas, two be equipped with the connecting rod of many crisscross settings between the dead lever, the filter cloth meanders through the setting of a plurality of many connecting rods.
Compared with the prior art, the surface type efficient cleaning centrifugal ventilator for the acid gas has the advantages that:
1. by arranging the alkaline solution, when the main body starts to work, a large amount of wind is sucked from the air inlet cylinder, at the moment, the wind power drives the fixed plate to drive the rotating shaft to rotate, the rotation of the rotating shaft drives the driving wheel, the driving wheel drives the driven wheel to rotate through the belt, the driven wheel rotates to enable the winding roller to rotate and simultaneously push the filter cloth to move, the filter cloth is infected with a certain amount of alkaline solution when passing through the reaction box and then penetrates through the side wall of the air inlet cylinder and enters the air inlet cylinder, and returns to the other coiling roller again through the guiding of the connecting roller, the filter cloth forms a triangular arrangement in the air inlet cylinder so that the filter cloth can carry out twice filtering and purification on the air, prevent acid gas in the air from entering the main body in large quantity to corrode and damage the main body, meanwhile, the damage to the health of residents caused by the fact that a large amount of acid gas is discharged through the output end of the main body and enters the room is avoided.
2. According to the invention, by arranging the filter cloth, due to the structural characteristics of the filter cloth, a large amount of dust and pollutants in the air can be adhered after liquid is absorbed, and the dust and pollutants in the air can be cleaned and removed while the neutralization reaction is carried out on the air acid gas, so that the main body is protected from being damaged by the air dust and the acid gas, the cleanness degree of the air discharged by the main body is higher, and the safety guarantee is stronger.
3. According to the invention, the plurality of connecting rods are arranged, the filter cloth moves in the air inlet cylinder for a whole circle, a large amount of dust and pollutants are attached to the surface of the filter cloth with high probability, and after the filter cloth enters the reaction box, the connecting rods and the fixing rods are continuously rubbed when the filter cloth advances forwards due to the existence of the fixing rods and the plurality of connecting rods, so that dust which is not filtered is well scraped, and the filter cloth is more easily cleaned due to friction and secondarily adsorbs alkaline solution by matching with the temperature generated by acid-base neutralization reaction, so that the filter cloth is prevented from losing the purification effect due to continuous adhesion of the dust.
