Improved corrugated plate structure

Abstract

The invention provides an improved corrugated plate structure. The air flow of the corrugated plate is increased, and the liquid drop gathering frequency is high, so that the efficiency of forming liquid drops by entrainment is high, the demisting effect is improved and the separation effect is good. The improved corrugated plate structure comprises a corrugated plate body and is characterized in that a wave front of the corrugated plate body is a platform wave front. The invention also provides a demister employing the corrugated plate structure.

Description

technical field [0001] The invention relates to the technical field of gas-liquid (mist) separator components, in particular to an improved corrugated plate structure. Background technique [0002] Smaller oil droplets that cannot be removed in the gravity settling section of the oil-gas separator need to be removed by a mist eliminator, mainly by collision and condensation. At present, the demisters commonly used in the gas outlet of the oil-gas separator include wire mesh pad demisters and corrugated plate demisters. The wire mesh mat demister has a relatively high separation efficiency, and can remove 99% of the droplets with a diameter greater than 10um from the airflow, and the price is relatively cheap, but it is easy to block and local erosion, and the pressure drop is large, so it is not suitable for use with dirt And solid particles and viscous fluids, and when the flow velocity is high, it may cause local erosion of the mist eliminator. Ordinary corrugated plate ...

The wire mesh mat demister has a relatively high separation efficiency, and can remove 99% of the droplets with a diameter greater than 10um from the airflow, and the price is relatively cheap, but it is easy to block and local erosion, and the pressure drop is large, so it is not suitable for use with dirt and solid particles and viscous fluids, and when the flow velocity is high, it may cause local erosion of the demister

Ordinary corrugated plate demisters are generally used for vertical flow of gas and liquid, and are not sensitive to dirt. Corrugated plate demisters include corrugated plate combinations, see figure 1 , the existing corrugated plate is a zigzag corrugated plate. The diffusion of the mist on the surface of the corrugated plate and the gravity settlement of the mist make the mist form larger droplets and move forward with the airflow to the turning of the corrugated plate. Due to the centrifugal force And its friction with the corrugated plate, adsorption and the surface tension of the liquid make the droplets bigger and bigger until the accumulated droplets are so large that the gravity generated by themselves exceeds the resultant force of the rising force of the gas and the surface tension of the liquid. The droplets are separated from the surface of the corrugated plate, and the droplets generally gather at the turning of the corrugated plate. The corrugated plate with this structure has a small air flow, and the number of droplets gathered is small, and the efficiency of the mist to form droplets is low. The separation effect Difference
