Description
Technical field
The utility model relates to a kind of grey gas mixing arrangement that is used for the semi-dry desulphurization reactor.
Background technology
Normal utilization rate and the desulfuration efficiency that adopts desulphurization ash circulation humidifying technology to improve desulfurizing agent of semi-dry process flue gas desulphurization technology; Flue gas desulfurization gets into reactor after deduster removes the most of desulphurization ash and the back mode through overflow of fresh desulfurizing agent humidification mixing of getting off; Remove materials such as sulfur in smoke with the hot flue gas haptoreaction that boiler comes out; Circulation through desulphurization ash; Effective desulfurizing agent content increases greatly in the reactor, has improved desulfuration efficiency, and the load of ash also improves greatly in the reactor.Whether on the cross section, evenly distributing behind the combination ash entering reactor, it is big related that flue gas desulfurization effect quality is had, also the stable operation to reactor has certain influence.
When existing grey gas mixing arrangement gets into reactor in the humidification combination ash overflow of a large amount of desulphurization circulating ashes and fresh desulfurizing agent; Can not on the whole cross section of reactor, evenly distribute, gas cleaning can not efficiently be moved, the circulation of a large amount of desulphurization ash; Increased ash load in the reactor; Exhaust gas volumn hour, exhaust gases passes is stopped up in the whereabouts that is prone to take place combination ash.
The utility model content
The purpose of the utility model is to provide a kind of grey gas mixing arrangement that is used for the semi-dry desulphurization reactor; Can effectively solve existing grey gas mixing arrangement and can not the humidification combination ash evenly be distributed the problem that gas cleaning can not efficiently be moved on the whole cross section of reactor.
In order to solve the problems of the technologies described above; The utility model is realized through following technical scheme: a kind of grey gas mixing arrangement that is used for the semi-dry desulphurization reactor; Comprise grey gas mixer; The lower port of said grey gas mixer is a smoke inlet, and the port of said grey gas mixer is an exhanst gas outlet, and the cross-sectional area of said exhanst gas outlet is greater than the cross-sectional area of smoke inlet; The right flank of said grey gas mixer has the combination ash inlet, is provided with downward-sloping distribution grid in the grey gas mixer of said combination ash inlet below.
Preferably, it is parallel after the switching of the left side of said distribution grid has lengthened plate, said lengthened plate to rout up with distribution grid; When flue gas flow hour, use lengthened plate to reduce the flue gas circulation area, increase velocity of flue gas, promote the lifting force of ash, make combination ash can not fall to causing exhaust gases passes to stop up.
Preferably, dual-side is equipped with dust block board before and after the said distribution grid; Dust block board makes combination ash be unlikely to along front and back that side plate falls, and influences the even distribution of combination ash.
Preferably, the cross section of said dust block board is a right angled triangle, and said dust block board broadens from right to left gradually; Make things convenient for combination ash to glide, the combination ash at edge is drawn close to the centre as far as possible along distribution grid.
Preferably, said dust block board right-hand member drift angle is β, and said β is 5～10 °, and the height of said dust block board is 80～150mm; This angle of dust block board can glide combination ash preferably along its side, the excessive height of dust block board can cause waste, and crossing short combination ash can cover from dust block board.
Preferably; The cross section of said grey gas mixer is a rectangle; The left end of said smoke inlet and exhanst gas outlet is on same perpendicular, and the left side of said smoke inlet and the distance of right edge are L2, and said distribution grid left end is positioned at the left side of smoke inlet right plate in the projection of vertical direction; Said distribution grid left end is L1 apart from the distance of smoke inlet right plate, and said L1 is 10%～30% of a L2 length; Best distribution grid outreach can make combination ash mix comparatively uniformly with flue gas.
Preferably, it is L3 apart from the horizontal range on the left of the smoke inlet that said lengthened plate is routed up the back, and the left side of said exhanst gas outlet and the distance of right edge are L4, and the length of said L3 is 20%～50% of L4 length; The best outreach of lengthened plate hour can promote velocity of flue gas preferably at flue gas flow.
Compared with prior art; The utility model has the advantages that: flue gas gets into from the smoke inlet of grey gas mixer bottom; Combination ash gets into from the combination ash inlet; Effect through distribution grid evenly distributes combination ash and mixed being incorporated in the whole cross section of flue gas excitation, makes smoke eliminator keep efficient operation.
