Abstract
The invention relates to a high-efficiency rarely-scaling demister. The high-efficiency rarely-scaling demister comprises a channel surrounded by a baffle plate, wherein a flow turbulence part is arranged at the turning part of the channel, the flow turbulence part divides the turning part of the channel into two shunting passages, the sum of the areas of the cross sections of two shunting passages is less than the area of the cross section of the other part of the channel; when the sum of the areas of the cross sections of the two shunting passages is less than the area of the cross section of the other part of the channel, the flowing speed of gas in each shunting passage is higher than that of the gas in the other position in channel, as each shunting passage is arranged at the turning position of the channel, entrainments in the gas can impact the baffle plate at high speed, and the demisting efficiency of the demister is improved greatly; and besides, the flowing speed of the gas in each shunting passage is higher than that of the gas in the other position in the channel, liquid drops at the turning position cannot be gathered easily, the liquid drops can be gathered at the areas at the upper part or the lower part of the turning position relatively easily, and the areas are spraying pipes which can be washed easily, so that the scaling can be effectively prevented.
Description
Technical field
The present invention relates to technical field of desulfurization, especially relate to a kind of less scaling high efficiency demister.
Background technology
Absorption tower is in running, easy generation particle diameter is " mist " of 10--60 micron, " mist " is not only containing moisture, it is also dissolved with sulfuric acid, sulfate, sulfur dioxide etc., also causes staining and heavy corrosion of blower fan, heat exchanger and flue, therefore simultaneously, wet desulfurizing process proposes the requirement of demist to absorption equipment, cleaned gas wanted demist before leaving absorption tower, and in desulfurizing tower, this step of demist all relies on demister to complete.
Demister is divided into baffling half formula and circular pipe type two kinds, the principle of baffle type mist eliminator: when the gas containing mist flows through demister with certain speed, due to the inertial impaction effect of gas, mist and deflection plate collide, then be attached on deflection plate and form drop, drop, under gravity gradually toward dirty, forms larger drop with other liquid polymeric in dirty process gradually.When arrived greatly by the drop gathered climbing power that the gravity that himself produces exceedes gas and surface tension of liquid with joint efforts time, drop just gets off from deflection plate is separated on the surface.
The solid particle contained in drop on deflection plate, the surface being easily attached to deflection plate forms soft dirt, if these soft dirts are cleared up not in time, in the course of time, soft dirt just becomes hard scale, thus causes demister to block.Therefore the shower be all provided with for rinsing demister above and below demister.But the opening between the deflection plate of this demister is very little, shower is difficult to the corner being washed into deflection plate, and this just causes the soft dirt of corner cumulative, form hard scale, thus make shower more be difficult to remove, form vicious circle, finally still demister can be caused to block.
The demister of circular pipe type, demister forms by three layers of pipe are staggered, and this demister principle is substantially identical with baffle plate type, and different places is that mist and pipe collide, and is then attached to pipe surface and forms drop.The all surface shower of the demister of circular pipe type can pour, and all surface of demister is all rounder and more smooth, so be not easy fouling.But this demister surface is too round and smooth, in gas, the collision of drop is not very strong, therefore this demister except fog effect be not fine.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, provide a kind of less scaling high efficiency demister, combine the advantage of baffle type mist eliminator and circular pipe type demister.
In order to solve the problems of the technologies described above, the present invention is solved by following technical proposals: a kind of less scaling high efficiency demister, comprise the passage that deflection plate surrounds, the turnover position of described passage is provided with flow-disturbing part, the turnover position of described passage is divided into two runners by described flow-disturbing part, and the sectional area sum of two described runners is less than the sectional area of described passage remainder.Sectional area sum due to runner is less than the sectional area of described passage remainder, gas flow rate in runner will faster than the flow velocity of all the other positions in passage, because runner is positioned at the turnover position of passage, this also causes the mist in gas to hit deflection plate with higher speed, greatly improves the demisting efficiency of demister.Also because the gas flow rate in runner will faster than the flow velocity of all the other positions in passage, the drop of turning point is not easy to converge, drop more easily converges to top or the bottom of turning point, and these places are also the regions that shower easily washes away, and therefore effectively can prevent fouling.
In technique scheme, preferably, the passage that described deflection plate surrounds has two kinds, the first passage, the deflection plate in centre position is all toward evagination, formed one broad in the middle, the passage of narrowing toward each end, described flow-disturbing part is positioned at the centre position of the first passage, the second passage is positioned at the interval of the first passage described in adjacent two, and the deflection plate in described the second passage centre position, all toward indent, forms two ends large, middle little passage, is positioned at the end positions of the second passage described in described flow-disturbing part is positioned at.
In technique scheme, preferably, described flow-disturbing part is a cross section is circular bar or pipe.
In technique scheme, preferably, also comprise two pieces of baffle plates, the two ends of described deflection plate and described flow-disturbing part are fixed on described baffle plate.
In technique scheme, preferably, described spoiler is positioned at each face of passage is plane.
The present invention compared with prior art, there is following beneficial effect: the sectional area sum due to runner is less than the sectional area of described passage remainder, gas flow rate in runner will faster than the flow velocity of all the other positions in passage, because runner is positioned at the turnover position of passage, this also causes the mist in gas to hit deflection plate with higher speed, greatly improves the demisting efficiency of demister.Also because the gas flow rate in runner will faster than the flow velocity of all the other positions in passage, the drop of turning point is not easy to converge, drop more easily converges to top or the bottom of turning point, and these places are also the regions that shower easily washes away, and therefore effectively can prevent fouling.
