Description
Technical field
The present invention relates to a kind of demister that is used for branch separable flue gas drop and tiny solid particle, especially relate to a kind of combined defroster of demister.Belong to the cleaner technical field.
Background technology
Demister is to be used for separating the residual drop that accompanies in the moisture content flue gas and the demister of tiny solid particle.Demister is arranged on the top, absorption tower usually, is typically provided to two layers up and down.Its operation principle is: realize gas-liquid separation during blade by deviation in wave shape of residual drop and tiny solid particle under the effect of inertia force, residual drop and tiny solid particle are captured down.Our purpose is to want maximum balancedly to capture more residual drop and tiny solid particle, and makes the residual drop and the tiny solid particle that trap thinner.Actual capture effect is with following relevant:
1) the wavy curve shape of blade
2) angle of inclination (the big more resistance in angle of inclination is more little, the drop percent of pass is big more) of blade wavy curve placement
3) pressure of flue gas and flow velocity
4) flow of flue gas
5) distribution of flue gas flow rate and flow in the tower
6) the interior flue gas of tower flows through the effective area of demister
7) spacing between demister blades height and adjacent blades.
Above-mentioned factor also has influence on the pressure drop and the energy consumption of flue gas except that the capture effect that has influence on demister.In fact often above-mentioned some parameter such as flow velocity are controlled in the suitable scope.
The deficiency of existing V-arrangement demister performance:
1) well-known, fume desulfurating absorption tower all is the cylindrical vessel that diameter reaches tens meters in tens of rice, height, the speed of flue gas, flow direction, flow have very big difference at the diverse location (the particularly center in cross section and periphery) in cross section, flue gas easily forms turbulent flow, and contour brace summer makes tactic V-arrangement demister can't solve above-mentioned difference between two layers of the V-arrangement demists.
2) existing V-arrangement demister blade is equilateral shape, and demister unit all designs according to average discharge, in fact can cause the flow difference of two waist blades during the flow direction disalignment, makes the reentrainment of a side excessive easily;
3) existing V-arrangement demister is not all made overall structure for considering transportation, and is assembled at the scene by each assembly, needs more connector of consumption and rigidity good not as overall structure.
4) existing V-arrangement demister can only rectangular shape in the tower of circle, and non-rectangle shape all around can only be made blind plate, and whole effective actual internal area is tailed off.
Summary of the invention
The objective of the invention is to overcome above-mentioned deficiency, provide a kind of and can prevent that flue gas turbulization, reentrainment are little, good rigidity, effective many combined defrosters of actual internal area.
The object of the present invention is achieved like this: a kind of combined defroster, comprise first order demister layer, second level shape demister layer and flushing water system, and it is characterized in that:
Described first order demister by many rows section be "/" shape and " " the flue dust collecting device sequentially in a row arrange to consist of; And section be "/" shape and " " flue dust collecting device gap arrange; Second level demister is sequentially in a row arranged by the V-shaped flue dust collecting device of many rows section and is consisted of; The demister blade of second level demister is arranged to two kinds of equilateral V-arrangement and inequilateral V-arrangements; Wherein each of the first order and second level demister layer is got rid of day with fog and is arranged from bottom to top on airflow direction and mutually do not have a lateral shift
On airflow direction, have some independently supporting constructions between each eliminating day with fog of the described first order and second level demister layer, some supporting constructions link to each other with the both sides that each of the first order and second level demister layer is got rid of day with fog respectively, and this supporting construction has long support structure and two kinds of short supporting constructions, and long and short two kinds of supporting construction gaps are arranged;
Described flushing water system comprises outside flushing water system and interior flushing water system, outside flushing water system is arranged on outside the first order demister layer, fixedly connected with the supporting construction lower end, the interior flushing water system is arranged between the first order and the second level demister layer, is connected with the center fixed of supporting construction.
The invention has the advantages that:
1, can a shared supporting construction between two layers of demister, can reduce by two layers of height between the demister, with the pressure drop and the energy consumption of flue gas; The supporting construction that adopts length to differ can be divided into the zone with flue gas in the absorption tower, prevents the flue gas turbulization.
2, the both sides of the demister blade of second level demister are made equilateral and inequilateral, can determine its length according to flow velocity, direction and the flow distribution of flue gas in the absorption tower, make with the absorption tower in the flow velocity and the flow distribution of flue gas agree, avoid occurring reentrainment to improve the demist ability of demister, increase the through-flow exhaust gas volumn of demister blade.
3, the combination demister is made overall structure, has improved the rigidity of demister, and the connector that consumes is less.
4, be arranged in the first order demister layer and the rectangular layout of second level demister layer of middle part, absorption tower, the first order demister device and the second level demister device that are arranged in both sides, absorption tower sector region are made skewed.Can improve actual internal area effectively like this.
5, being positioned the middle interior flushing water system of supporting construction makes the flushing water system architecture more simple.And developing result is good, be not easy incrustation.
