Description
Technical field
The utility model belongs to the cleaning equipment field of flue gas, is specifically related to a kind of desulfurizing tower inlet flue gas even distribution device.
Background technology
More and more stricter along with Environmental Protection in China standard, original Limestone-gypsum Wet Flue Gas Desulfurization Process system can not meet the requirement of qualified discharge all, and during desulphurization system transformation, conventional technology has increase liquid-gas ratio, increases gas liquid interfacial area and time of contact etc.By finding the research of wet desulphurization absorption tower, by coverage rate and nozzle is uniform, adopt the methods such as hollow cone nozzle to make slurries side uniform as far as possible.Then pole is not uniform at ground floor and second layer spraying layer conversion zone for fume side, reduces gas liquid interfacial area, thus affects smoke desulfurization efficiency.In order to make fume side uniform, conventional method arranges guiding device at desulfurizing tower entrance exactly, arranges alloy pallet in ground floor spray below.But alloy pallet resistance is large, about 1000Pa, and perforate is small and dense, and in longtime running situation, the easy fouling of pallet.
Utility model content
The purpose of this utility model is for overcoming above-mentioned the deficiencies in the prior art, a kind of wet desulfuration tower inlet flue gas even distribution device is provided, while improving the uniform effect of original desulphurization system fume side, the resistance of desulphurization system can be reduced, and effectively can avoid the scale problems of alloy pallet.
For achieving the above object, the utility model adopts following technical proposals:
A kind of wet desulfuration tower inlet flue gas even distribution device, comprise multiple flue gas even distribution unit, described flue gas even distribution unit bottom is provided with support steel beam, plays a supporting role to flue gas even distribution unit; Described flue gas even distribution unit comprises stainless steel bare tube, and described stainless steel bare tube top is fixedly connected with ridge type anti-block apparatus.
Described ridge type anti-block apparatus comprises into two pieces of corrosion resistant plates that set angle is fixedly connected with, and two pieces of corrosion resistant plate one end are fixedly connected with, other end opening; Can effectively prevent the lime stone slurry fallen from splashing.
Edge and the stainless steel bare tube of described two corrosion resistant plate openings are tangent; The local dip of flue gas from bottom to top can be effectively reduced, thus reduce the resistance of device.
The angle of described two corrosion resistant plates is 72-76 °, under remaining on different tube diameters, ridge type anti-block apparatus and light pipe tangent.The angle of two corrosion resistant plates is unsuitable too small, contacts more fully with flue gas to keep lime stone slurry.
Described flue gas even distribution cell layout in desulfuration absorbing tower entrance, alloy pallet place below spraying layer; Make flue gas equably with orlop spraying layer spray under lime stone slurry fully contact.
Gap between the stainless steel bare tube of described adjacent flue gas even distribution unit is 5-8mm; Test with under analog result is presented at this gap, maintenance lime stone slurry and smoke contacts respond well while, the resistance of device is minimum.
The beneficial effects of the utility model are:
By the flue gas after flue gas even distribution device of the present utility model equably with orlop spraying layer spray under lime stone slurry fully contact.Ridge type anti-block apparatus effectively can prevent the splashing of the lime stone slurry fallen, add the limestone slurry flow quantity by flue gas even distribution device in the unit interval, effectively improve the local liquid-gas ratio in flue gas even distribution device, improve the mass transfer effect of gas phase and liquid phase simultaneously, thus under identical design parameter, the desulfuration efficiency of flue gas is improved.Device resistance is also less than alloy pallet simultaneously.

Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further illustrated.
As shown in Figure 1, wet desulfuration tower inlet flue gas even distribution device, is installed in desulfuration absorbing tower entrance 5, the installation site of alloy pallet 6 below fourth stage spraying layer 7.Fourth stage spraying layer 7 is positioned at below third layer spraying layer 8.
As shown in Figure 2, flue gas even distribution device forms primarily of two parts, multiple flue gas even distribution unit 1, and the support steel beam 4 of whole device forms.Each flue gas even distribution unit and desulfurizing tower inwall are welded to connect, and are carried by vertically arranged support steel beam 4.
As Figure 3-Figure 4, flue gas even distribution unit 1 is made up of stainless steel bare tube 3 and ridge type anti-block apparatus 2, and stainless steel bare tube 3 adopts
stainless steel tube, according to the requirement of exhaust gas volumn and crushing, gap wherein between adjacent two stainless steel tubes is 5-8mm, namely the center distance of adjacent two stainless steel tubes is 81-84mm, ridge type anti-block apparatus is welded according to certain angle by the corrosion resistant plate that two panels is very thin, the angle of two panels corrosion resistant plate be 72-76 ° and edge and stainless steel tube tangent, by being welded to connect between ridge type anti-block apparatus and stainless steel tube.
