[0005] However, in this structure, since the baffle plate and swirl plate demister do not get rid of the gravity separation control link, the air flow direction still adopts longitudinal flow, and the downward gravity is used to get rid of the gas phase, and its separation efficiency is lower than that of the wire mesh demister. Effervescent, especially in the case of dealing with gas-liquid mixtures containing a small amount of solid particles, resulting in lower efficiency of the system

Abstract
The invention discloses a compound defoamer, which comprises a body with a cavity, wherein a gas liquid mixture containing solid particles enters the body from an inlet formed in the lower part of thecavity and upwards and sequentially passes through a blade type defoamer and a baffle plate defoamer; separated gas is output from a gas phase outlet formed in the top; the blade type defoamer comprises a plurality of blades in mutually parallel arrangement; a defoaming passage is formed between the parallel blades; the single blade is formed by a vertical section and a bent section through staggered connection; a connecting position of the upper part of the bent section and the vertical section is positioned in a position with a distance being 1 / 5 to 1 / 7 of the height of the vertical sectionfrom the bottom; a V-shaped structure with a downward opening is formed; the baffle plate defoamer comprises at least two groups of corrugated sheep packings in vertical stacking; the vertically adjacent two groups of corrugated sheep packings are in 90-degree arrangement.
Description
technical field [0001] The invention relates to a separation device used in the chemical industry. More specifically, the present invention relates to a compound demister for demistering gas-liquid mixture. Background technique [0002] The existing demisters used in the chemical industry mainly consider the large fluctuations in the pressure and gas velocity in the tower, the high gas velocity, the large amount of liquid leakage in the upper airflow of the tower, the large amount of liquid droplets and foam carried by the airflow, and the purity of the distilled gas phase. And metal ions and other indicators require strict occasions. For example, bubble cap towers, sieve tray towers, washing packed towers, absorption towers, distillation towers, especially high vacuum rectification towers, flash towers, regeneration towers, etc., are all considered to be equipped with demisters. Tower demisters can be roughly divided into vane demisters, wire mesh demisters, baffle plate ...
