According to embodiment of the present utility model, provide a kind of combined type desulfurizing tower.
As depicted in figs. 1 and 2, according to the combined type desulfurizing tower of the utility model embodiment, comprise thering is inside and outside double-deck desulfurizing tower tower body 1, the internal layer of described desulfurizing tower tower body 1 is granite inner liner 2, the skin of desulfurizing tower tower body 1 is the mixed earth surrounding layer 3 of reinforcing bar, the top middle portion of described desulfurizing tower tower body 1 is provided with exhanst gas outlet 4, the top of desulfurizing tower tower body 1 is provided with some layers of demister 5, the both sides up and down of described demister 5 are distributed with respectively flushing pipe 6, on flushing pipe 6, be evenly provided with some flooding nozzles, the middle part of described desulfurizing tower tower body 1 is provided with some layers of shower 7, on shower 7, be evenly provided with some spray spouts, between adjacent two showers 7, be provided with spiral board 8, the bottom of described desulfurizing tower tower body 1 is provided with gas approach 9, the bottom of desulfurizing tower tower body 1 is provided with drainpipe 10.
In actual production, the number of plies of described demister 5 is chosen as 2 layers, the number of plies of shower 7 is chosen as 3～6 layers, between adjacent two demisters 5 and between adjacent two showers 7, can be made as equidistant distribution and arrangement parallel to each other, between adjacent two layers flooding nozzle and between adjacent two layers spray spout, can be made as mutual dislocation intersection and be uniformly distributed.In addition, for maintenance in the future, can be provided with in the bottom of desulfurizing tower tower body 1 manhole 11, and the position corresponding with every layer of demister 5 and every layer of shower 7 is equipped with the inspection rack 12 that a circle is close to desulfurizing tower tower body 1 outer wall on described desulfurizing tower tower body 1.
By design principle, technique scheme of the present utility model is illustrated below.
In the utility model, desulfurizing tower tower body 1 is made as to double-decker, internal layer is granite inner liner 2, and outer is the mixed earth surrounding layer 3 of reinforcing bar, wherein:
Granite material compact structure, gap little (porosity is generally 0.3%～0.7%), water absorption rate not high (water absorption rate is generally 0.15%～0.46%), has good anti-freezing property; The hardness of granite is high, and its mohs hardness is in 6 left and right, and than the high 2-3 of cast iron doubly, so precision stability is good, can reach below 0.5 μ m, even if collided with by weight, falls at the most several rock ballasts, can be as metal, because distortion destroys precision; Wear-resistant degree is 0.08-0.22g/cm3, extremely wear-resistant, than the high 5-10 of cast iron doubly; Its density is at 2.63g/cm3 between 2.75g/cm3, and its compressive strength is at 100-300MPa, and wherein granitello can be up to more than 300MPa, and flexural strength is generally at 10～30Mpa, so it is very hard, does not fall chip, is difficult for scratch, is not afraid of high temperature.And it is contaminated hardly, surface of polished glossiness is very high, and the impurity that various flue gases bring nearly all can not adhere to, acid and alkali-resistance, and chemical stability is good.Solve the shortcoming that carbon steel glass inner-lining scale desulfurizing tower can not at high temperature move.
Armored concrete is the mixture of reinforcing bar, cement, coarse-fine aggregate (rubble) and water, has the features such as anti-seismic performance is good, globality is strong, resistance to corrosion is strong, durable in use.The thermal coefficient of expansion of armored concrete is 6-12 * 10-6/ ℃, temperature influence is atomic, not yielding, differ very little with the thermal coefficient of expansion (4.61 * 10-6/ ℃) of granite, make both form the combination of good interface, because it is whole that concrete caking property becomes a kind of reliable and stable mechanical connection, form a kind of new material, this structure is equivalent at steel and concrete structure liner one deck corrosion-proof wear-resistant material, worn a set of waterproof coat to granite absorption tower, integrate the advantage of bi-material, made up mutually shortcoming separately.Solved the problem that numb stone desulfurizing tower cannot operation under positive pressure.
In sum, by means of technique scheme of the present utility model, by desulfurizing tower tower body 1 is set to double-decker, internal layer is granite inner liner 2, outer for the mixed earth surrounding layer 3 of reinforcing bar, make desulfurizing tower there is lasting high temperature resistant, corrosion-resistant, wear-resistant, impact-resistant mechanical performance; With other materials comparison, there is larger economy, longer service life.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
