Abstract
The utility model discloses a cyclic desulfurization absorption tower for organic amines. The absorption tower is of a packless empty tower structure, is low in pressure drop and is used for solving the problem of high system back pressure. The absorption tower is provided with a circulating liquid pool, an absorption and spraying section and a demisting layer which are arranged from bottom to top, wherein a disturbing device, a gas inlet and a gas distributor are arranged in the circulating liquid pool; the absorption and spraying section is provided with two stages of spraying systems, and each stage of the spraying system consists of multiple layers of spraying devices; and the demisting layer consists of two stages of demisting devices, each stage of the demisting device is provided with a flushing system, and purified gas is exhausted from a gas outlet at the top of the tower. The cyclic desulfurization absorption tower for the organic amines has the advantages that the number of components in the tower is small, the system resistance is low, the operation is stable and reliable, and the investment is low.
Description
Technical field
The utility model relates to a kind of organic amine circulation desulfurization absorption tower, is that organic amine removes the equipment in hydrogen sulfide and the sulfur dioxide technology, belongs to the gas purification field.
Background technology
At present, petroleum chemical enterprise's organic amine commonly used removes hydrogen sulfide and sulfur in smoke in dry gas, natural gas, the liquefied gas.Organic amine circulation desulfurization technology desulfurizing agent regeneration easily, low temperature absorption, the high temperature desorb realize desulfurizing agent regeneration, recycle, loss is low; Amine method sulfur removal technology produces the poor relatively scarce byproduct of domestic resource simultaneously, and accessory substance purity is high, value is high.The amine method is taken off the desulfurizing tower of using and is mainly contained packed tower, plate column, bubble tower etc., wherein adopts packed tower building or built engineering more.Absorption plant does not circulate in packed tower, plate column, bubble tower complex equipments, the difficult in maintenance and tower; These three kinds of towers can effectively increase the gas-liquid contact area, but resistance is big, cause the desulfurizing tower system back pressure big, and generating has a negative impact to upper reaches fume afterheat, if the upper reaches of gas sweetening simultaneously dust removing effects does not with great difficulty cause filler to stop up and stops work.The utility model provides a kind of organic amine circulation desulfurization absorption tower, and this tower is a spray column, and system pressure drop is little, has overcome the big defective of traditional amine method desulfurizing tower system back pressure.The tangential gas distributor that is provided with in the tower can make gas fully contact with absorption liquid with special spray equipment; Overcome the not high shortcoming of traditional spray column gas liquid contacting efficiency; Be provided with circulation liquid pool and two-stage circulated sprinkling system in the tower body simultaneously; Effectively increase the utilization rate of absorption liquid, improved desulfuration efficiency.
The utility model content
The utility model provides a kind of organic amine circulation desulfurization absorption tower, and this tower is a spray column.The multilayer spray equipment has replaced filler, has simplified housing structure greatly, and convenient operating maintenance is provided with the tangential gas distributor in the tower simultaneously, and the sulfurous gas that the tangential is got in the tower evenly disperses; Special spray equipment mechanism design can make gas fully contact with absorption liquid, and effectively spray area can reach 200%; Be provided with circulation liquid pool and two-stage circulated sprinkling system in the tower body, effectively increased the absorption rate of absorption liquid, thereby improved desulfuration efficiency.
The utility model is realized through following technical scheme:
This organic amine circulation desulfurization absorption tower is made up of tower body, tower body bottom cycle liquid pool, circulation liquid pool disturbance device, gas feed, gas distributor, two-stage spray system, two-stage demist layer, two-stage washing device, gas vent, recycle liquid pump and lean pump.Be characterized in: gas tangentially gets into the absorption tower by gas feed; The gas feed top is provided with one deck tangential recycle stream distributor; The spray absorption liquid is transported to the two-stage spray system by recycle liquid pump and lean pump; The top on absorption tower is provided with two-stage demist layer, and every grade of demist layer all is equipped with the two-stage washing device up and down.
Described two-stage spray system is formed by 1～3 layer of spray equipment, and the central tube horizontal sextant angle of adjacent two layers spray equipment is 15 °～30 °.
The spray absorption liquid of described two-stage spray system, first order spray system absorption liquid come from the lean solution after Analytic Tower is resolved, and second level spray system absorption liquid comes from tower body bottom cycle liquid pool.
Described two-stage demist layer is respectively " Z " shape flap demister and screen waviness packings from bottom to top.
