High efficient whirl tray suitable for ship exhaust gas washing tower

Abstract

The invention discloses a high efficient whirl tray suitable for a ship exhaust gas washing tower. The tray comprises a connection plate and a plurality of whirl components arranged on the connectionplate. The connection plate is provided with a plurality of through holes. Each whirl component comprises an outer cylinder, an inner cylinder, and a whirl blade arranged on the outer wall of the inner cylinder. The bottom of the outer cylinder is provided with a drainage inlet for introducing an absorbent. Each whirl component comprises a peripheral whirl component arranged on the inner wall of the whirl tray and an internal whirl component that is close to the center of the whirl tray. The peripheral whirl component is provided with a drainage component for introducing an absorbent. The drainage component comprises a drainage pipe and an annular pipe arranged on the inner wall of the outer cylinder. One end of the drainage pipe is arranged on the external side of the outer cylinder and extends outwards, and the other end is communicated with the annular pipe. The side, which is close to the whirl blade, of the annular pipe is provided with a plurality of round holes. Through the whirling effect of the whirl component, the absorbent is broken into droplets, which carry out complete reactions with flue gas, moreover, the flue gas that escapes from the peripheral areas can be effectively captured, and the flue gas desulfurization efficiency is improved.

Description

technical field [0001] The invention relates to the field of desulfurization and environmental protection equipment, in particular to scrubber equipment for treating ship waste gas. Background technique [0002] With the increasingly stringent national environmental protection policies, most of the exhaust gas used by ships needs to be desulfurized. Ship desulfurization technology mainly absorbs polluted gases through scrubbers. Its main working principle is: the flue gas enters the inside of the washing tower and reacts with the sprayed absorbent, and the harmful gases and particles contained in it are absorbed by the absorbent. After the purification reaches the standard, the flue gas is discharged to the atmosphere through the demister. Therefore, the purification effect of the scrubber is directly related to whether the whole set of desulfurization equipment is up to standard. [0003] The washing towers currently used are mostly spray towers, packed towers, and sieve ...

AI Technical Summary

Problems solved by technology

[0004] The present invention mainly solves the problem of poor mixing effect of lye and absorbent in existing waste gas desulfurization treatment devices, and provides a high-efficiency swirl tray suitable for ship waste gas scrubbers, which has the purpose of desulfurizing ship tail gas, This solution reduces the pressure loss of the flue gas while improving the flue gas purification efficiency
