Description

Plate type multi-bag vane separator with heat transfer function

Technical Field

The utility model relates to a gas-liquid separation technical field relates to a board-like many bags of blade separator of area heat transfer function particularly.

Background

In the industrial fields of chemical industry, petroleum refining, environmental engineering, organic solvent solution recovery, steam waste heat recovery and utilization, pharmacy, environmental protection and the like, the separation of tiny liquid foam and liquid drops carried in air flow is a key technology in the fields. The principle of demisting mainly comprises centrifugal force, inertial collision, gravity settling, diffusion movement, electroanalysis and the like, in terms of separation technology, the gravity settling mainly removes liquid drops with the particle size of more than 50 mu m, the centrifugal force and the inertial collision mainly remove liquid drops with the particle size of 1 mu m-50 mu m, only the electroanalysis and other technologies can be adopted for mist liquid drops with the particle size of less than 1 mu m, for separated gas, the condensation of water vapor in the gas caused by temperature loss on the way does not have a good solution, a large amount of water vapor can be generated (the mass concentration of condensed water is 2-5 g/m in a thin section) when the temperature on the way is reduced by 1), and the condensed liquid can be further condensed and aggregated into large liquid drops to enter a next working section.

At present, most enterprises at home and abroad still adopt a grid inertial collision type gas-liquid separator in the industry field, such as a wire mesh type demister and a baffle plate type demister, and the grid inertial collision type gas-liquid separator adopted by most domestic projects has the advantages of high demisting efficiency, simple manufacturing and processing and the like, but also has a plurality of defects at the same time: for example, the operation flexibility is low, the passing gas speed is low, the collected liquid is not separated in the future, secondary entrainment is easy to generate, and when the separated gas contains particles and dust with crystallization tendency, the channel is easy to block, and the gas to be treated is required to be cleaner.

At present, many enterprises also adopt an inertial collision principle to separate the mist, and the baffle separator utilizes the inertia of the mist particles in the moving air flow, and the mist particles deviate from the flow direction of the air flow under the action of the inertia by suddenly changing the flow direction of the mist-containing air flow and are separated (removed) by impacting on a baffle plate. The fog-containing airflow changes the flowing direction under the action of the baffle plate, the fog particles are separated by utilizing the inertia of the fog particles, the fog-containing airflow is similar to an inertial dust collector, the deflection angle is large, the airflow speed is high, the distance between the baffle plates is small, the fog removal efficiency is high, but the resistance loss is large. In addition, too high a velocity will secondarily entrain the trapped mist particles in the airflow. These factors are matched to achieve a suitable and efficient baffle separator.

As such a gas-liquid separator, a baffle demister as shown in patent documents 1 to 3 is known, for example.
