Spraying tower spraying device capable of efficiently removing dust based on new OG system

Abstract

The invention discloses a spraying tower spraying device capable of efficiently removing dust based on a new OG system. The spraying tower spraying device comprises a spraying tower body, the bottom of the spraying tower body is provided with an air inlet, the top of the spraying tower body is provided with an air outlet, the spraying tower body is internally provided with a cover body, and the bottom of the outer ring of the cover body is provided with a connecting rod; rotating shafts are uniformly arranged on the outer ring surface of the cover body, a gear is arranged in the cover body, blades are arranged outside the cover body, a limiting ring is arranged above the rotating shafts, a mounting plate is arranged on the inner wall of the cover body, a motor is arranged on the top surface of the mounting plate, and a first gear is arranged on the left side of the motor; a gear ring is arranged at the top of the first gear, a first gear ring is arranged on the top face of the gear ring, a rotating ring is arranged on the outer ring face of the first gear ring, and an annular groove is formed in the upper portion of the spraying tower body. The device has the advantages that the efficient and uniform water spraying function is achieved, and the waste gas rotational flow effect is controlled by adjusting the blade angle.

Description

technical field [0001] The invention relates to the field of spray towers, in particular to a high-efficiency spray tower injection device based on a new OG system for dust removal. Background technique [0002] The spray tower is the simplest equipment for industrial dust removal or waste gas treatment. It has simple structure, low cost, small gas pressure drop, and will not be blocked. The working principle of the spray tower can be divided into three types: forward flow, reverse flow and cross flow. Among them, the most commonly used method is the countercurrent spray method: the acidic or alkaline acid mist waste gas is introduced into the purification tower through the air duct, passes through the packing layer, and the waste gas is sent from the bottom of the tower and distributed through the gas distribution device (cyclone device) Afterwards, it passes through the gap of the packing layer continuously in countercurrent with the sodium hydroxide absorption liquid. ...

AI Technical Summary

Problems solved by technology

[0003] The existing spray tower equipment cannot completely filter the exhaust gas during use, and there are problems such as uneven water spraying, small area of ​​sprayed water, small contact area with exhaust gas, and low purification efficiency. The blades on the device are fixedly installed, and the angle of the blades cannot be adjusted, which leads to the inability to flexibly adjust the centrifugal velocity and flow rate of the exhaust gas after passing through the swirl device. The exhaust gas can only maintain a centrifugal velocity and flow rate in the spray tower, which seriously affects the exhaust gas flow rate. Purification efficiency, therefore, it is necessary to design a spray tower spray device with high efficiency, uniform water spray function and adjustable swirl device blade function based on the new OG system for dust removal and high efficiency
