Abstract
The invention discloses a gas-liquid separation device. A group of overlapped arc, crescent or other curve shaped separation pieces are arranged on an air runner, a curved channel is formed between every two adjacent separation pieces, and the plurality of separation pieces form a group of channels. Air flows through the group of channels, and changes from linear motion to curve motion in any one channel to generate the centrifugal effect, and droplets are thrown to the outside of the curved channels under the centrifugal effect, thereby realizing gas-liquid separation.
Description
Technical field
The present invention relates to a kind of gas-liquid separation device, realize the device of gas-liquid separation especially for the gas containing drop.
Background technology
Gas-liquid separation device is a kind of usual construction equipment, is used for chemical reactor tower top, boiler or vaporizer top, environmental protection equipment, for separating the drop in gas.Current existing gas-liquid separation device by operation principle can be divided into gravitational settling, inertial separation, cyclonic separation, electrically separated, filter, fibre web separate six kinds.
Gravity settling separation device arranges enlargement on gas flow, and after gas flow rate reduces, drop is settlement separate under gravity.Gravity settling separation device simple structure is reliable, but bulky, and can be only used for the separation of large scale drop.
Inertial separator arranges baffle plate on gas flow, and gas is intercepted by baffle plate, sharply changes flow direction, and drop is because of effect of inertia, and change in travel direction, less than air-flow change in travel direction, impinges upon on baffle plate, thus realizing separating.Inertial separator simple structure, pressure loss is relatively small, but can be only used for the separation of large scale drop equally.
Gas is introduced tangentially in cylinder by cyclone separator, and gas is high speed rotating within the barrel, and drop is got rid of to cylinder inner wall realization separation by air-flow because of centrifugal action.Cyclone separator small volume, the pressure loss is medium, it is possible to separates the drop of mesoscale, but needs higher gas initial flow rate.In addition cyclone separator diameter is unsuitable excessive, and in the occasion that treating capacity is bigger, the mode that one group of multiple minor diameter cyclone separator can only be adopted in parallel works, it is necessary to bigger I&M space.
Electrically separated device arranges high-pressure electrostatic electrode in gas flow both sides, forms electric field, and gas flows through from electric field, and the drop with electric charge is subject to electric field action, by electrode separation.Electrically separated unit efficiency is higher, it is possible to remove little yardstick drop, but the dielectric constant of drop be there are certain requirements.Additionally, civilian occasion, high-tension electricity possesses certain danger.
Filtering separation device arranges filter screen in gas flow and removes drop, and filter screen volume is little, and can remove all drops more than filter screen effective aperture.But high accuracy filter screen resistance is relatively big, and is prone to blocking, and practical value is less.
Fibre web segregation apparatus adopts fiber to form multiple large aperture filter screen structure in certain thickness space, and substance filter screen is inefficient to droplet capture, and multiple structure can obtain any high clearance in theory.Actually typical fibre web segregation apparatus thickness is typically in more than 100mm, and the clearance of fine drop is generally higher than 99.7%, and the pressure loss is typically in 200 1000Pa scopes.For the gas that fine drop content is higher, fibre web segregation apparatus resistance generally increases to some extent.If drop is unholiness, after life-time service, fibre web there is also the risk of blocking or fouling.
Summary of the invention
It is an object of the invention to overcome the deficiencies in the prior art, it is provided that a kind of weight is little, pressure drop is low, volume compact, can fully remove the gas-liquid separation device of drop.
The technical solution adopted in the present invention is: arrange the arc of one group of overlapping arrangement, crescent or other shaped form separating sheet on gas flow, forms a curved surface passage between two separating sheet of arbitrary neighborhood, and multiple separating sheet can form one group of passage.Gas flows through from this group passage, and in any one place passage, air-flow is become curvilinear motion from rectilinear motion, produces centrifugal action, and drop is thrown toward outside curved channel under the action of the centrifugal.Drop is inversely proportional to by the time of passage and gas flow rate, is directly proportional to the product of channel radius and passage deflection angle.Within this time, if drop arrives separating sheet surface, outside, can catch on separated surface, namely complete gas-liquid separation by the gas of this group passage.
Drop in air-flow, under the action of the centrifugal accelerated motion laterally, when air resistance is with centrifugal action balance, the speed of relative wind stops increasing.When Reynolds number is less, this speed of related movement meets Stokes equation, to square being directly proportional to be inversely proportional to gas viscosity and be directly proportional to centrifugal acceleration of drop yardstick.And centrifugal acceleration and speed square be directly proportional and runner radius is inversely proportional to.After runner radius change, centrifugal acceleration is changed by the time of separating sheet respectively round about with drop.
In sum, fully improve gas flow rate, reduce separating sheet distance, strengthen passage deflection angle, it is possible to be kept completely separate drop.
In physical device, gas flow rate is too high, and pressurization will consume more energy.Being unlikely under the premise of Severe blockage passage at drop, reduce separating sheet spacing is better selection as far as possible.
The invention has the beneficial effects as follows, it is possible to reduce the volume of gas-liquid separation device, pressure drop, improve removal efficiency, reduce and manufacture and operating cost.
