Summary of the invention
In order to overcome problems of the prior art, the utility model provides a kind of carbon steel of sulfur dioxide removal/granite combination tower, this compound tower body should adopt the compound tower body of carbon steel/granite, solve anticorrosion, the wear-resisting and insulation problem of desulfurization tower body, both eliminated corrosion-resistant, the not wear-resisting shortcoming of carbon steel tower body, remedied again granite (numb stone) deficiency that closure is poor though tower is corrosion-resistant, and needn't add again heat-insulation layer, tower body is prolonged and the reduction energy consumption service life.
The technical solution adopted in the utility model is: a kind of carbon steel of sulfur dioxide removal/granite combination tower, it comprises that is adopted a welded carbon steel tower wall, the inwall of described carbon steel tower wall is provided with hook, support granite slab with hook, allow granite slab be covered with the inwall of carbon steel tower wall, fill up the acid resistant adhesive mortar concrete in the space between carbon steel tower wall and granite slab, between the side of each adjacent granite slab, adopt furan mastic blind, and furan mastic is flushed with the inner face of granite slab.
One end of described hook adopts T shape structure, and the other end adopts structure of right angle tyoe, and hook adopts Stainless steel 316 L to make.
The side of described granite slab is provided with the groove that matches with the T shape structure of linking up with.
Described carbon steel tower wall adopts the structure of right angle tyoe of stainless steel electrode A312 and hook to weld together.
The beneficial effects of the utility model are: the carbon steel of this sulfur dioxide removal/granite combination tower, inwall at carbon steel tower wall is provided with hook, support granite slab with hook, allow granite slab be covered with the inwall of carbon steel tower wall, fill up the acid resistant adhesive mortar concrete in the space between carbon steel tower wall and granite slab, between the side of each adjacent granite slab, adopt furan mastic blind.This compound tower body adopts the compound tower body of carbon steel/granite, solved anticorrosion, the wear-resisting and insulation problem of desulfurization tower body, both eliminate corrosion-resistant, the not wear-resisting shortcoming of carbon steel tower body, remedied again granite (numb stone) though the poor deficiency of the corrosion-resistant closure of tower and needn't add heat-insulation layer again.A 80t/h carbon steel/granite combination tower, tower body can reach more than 20 years service life, because of good airproof performance, can adopt forced draft, air-introduced machine power is no more than 200kW, but every year more than 70 ten thousand yuan of power cost savings.

The specific embodiment
Referring to accompanying drawing structure of the present utility model is described further.
Fig. 1,2,3 shows the structure of a kind of carbon steel of sulfur dioxide removal/granite combination tower.Among the figure, the inwall of the carbon steel tower wall 5 of the compound tower body of carbon steel/granite is provided with hook 3, and hook 3 adopts Stainless steel 316 L to make, and an end of hook 3 adopts T shape structure 3a, and the other end adopts structure of right angle tyoe 3b(shown in Fig. 4,5).Carbon steel tower wall 5 adopts stainless steel electrode A312 and the structure of right angle tyoe 3b of hook 3 to weld together.The side of granite slab 1 is provided with the groove that matches with the T shape structure 3a that links up with 3.Support granite slab 1 with hook 3, allow granite slab 1 be covered with the inwall of carbon steel tower wall 5, fill up acid resistant adhesive mortar concrete 2 in the space between carbon steel tower wall 5 and granite slab 1, between the side of each adjacent granite slab 1, adopt furan mastic 4 blinds and floating.
Adopting the carbon steel of technique scheme/granite combination tower is that cladding technology with granite in the architectural engineering is incorporated on the desulfurizing tower tower wall, use the 316L stainless steel, every block of granite is fixed on carbon steel tower wall inboard, between carbon steel wall and granite slab, build the acid-resisting concrete of predetermined thickness, fundamentally solved the anticorrosion of desulfurization tower body, wear-resisting and insulation problem, both eliminated the carbon steel tower body not corrosion-resistant, not wear-resisting shortcoming, remedied again granite (numb stone) deficiency that closure is poor though tower is corrosion-resistant, and needn't add again heat-insulation layer, tower body is reached more than 20 years service life, than conventional carbon head tower life one times; Reduce energy consumption more than 1/3rd than traditional granite (numb stone) tower.
For example: glass flake anticorrosive coat in the carbon steel desulfurizing tower that the 80t/h boiler flue gas desulfurization is used, its tower, needed to change once every two to three years, each expense is all more than 100,000 yuan.Even like this, the carbon steel tower body only has about 10 years because oozing corrosion in the acid solution service life.And the compound tower body of carbon steel granite can reach more than 20 years service life, and simultaneously, tower body does not need to carry out large repairs long-range remarkable in economical benefits in useful life; A same 80t/h granite (numb stone) desulfurizing tower, poor because of sealing, can only adopt negative pressure induced wind, air-introduced machine power reaches more than the 300kw.And a carbon steel granite composite desulfate tower because of good airproof performance, can adopt forced draft, and air-introduced machine power is no more than 200KW, but more than 70 ten thousand yuan of power cost savings in every year (by 7000 hours/year, 1.1 yuan/kW.h meter).
Above-mentioned carbon steel/granite combination tower adopts 4-5 millimeters thick carbon steel sheet to make the tower body peripheral structure, because sheet metal moulding and welding are easily, and good airproof performance, outside preservative treatment letter and easy row; Take the steel plate wall as support, adopt the cladding technology of granite slab, cladding steel joist layout is easy, and it is firm to weld, and can guarantee that the granite inwall is smooth smooth, and drawknot is firm; Adopt pouring concrete technique, utilize the compatibility of concrete and steel and granite, both are combined securely, both increased tower body intensity, protected again steel not to be subjected to the erosion of gas in the tower.
The technical problem that above-mentioned carbon steel/the granite combination tower should be noted is: will be thoroughly to carbon steel sheet rust cleaning abatement processes, and steel tie distributes rationally and is even; Cladding granite slab seam size is reserved rationally, adopted corrosion resistant fire resistant resin filleting, guarantee adhesion strength, do not produce seepage; Rational allocation acid-resistant and anti-high-temperature concrete adopts laminated pouring technique, guarantees the fully bonding of concrete and carbon steel sheet and granite slab; The prefabricated pre-buried PROCESS FOR TREATMENT of spray inlet, backwash entrance, checkout equipment entrance and access hole flange etc.
