Description
Technical field
The utility model relates to a kind of medium-sized tower diameter (φ 4500-7000mm) scope Si road supervisor's pipe-type high-efficiency acid trap of producing for vitriol oil relieving haperacidity.
Background technology
Acid trap is the vitals of dry absorption tower in vitriol oil production unit, and its point of sour effect directly has influence on the contact of gas-liquid, dry, assimilated efficiency, requires to have effect corrosion-resistant under harsh working condition, that wash away and resistance to certain temperature and pressure.SO
3specific absorption should reach more than 99.99%.40 DEG C～120 DEG C of acid temperature, pressure is less than 1.6MPa, point acid mouthful flow velocity 1.00～1.30m/s, expanding with heat and contract with cold etc. while being all subject to burn into wash away with temperature variation inside and outside acid trap affects, and working conditions is comparatively severe.Existing stainless steel tube bath type acid divider, due to the congenital defect that structure design exists, has caused the restriction of vitriol oil production efficiency and impact as follows:
1, ventilation cross section is little, and bottom land forms vortex resistance accelerates air-flow between groove, causes sour entrainment serious.Dried moisture is high, specific absorption is low, affects production efficiency, and environment is polluted, and point acid exists blind area, involves great expense etc.
2, when overflow tubule mouth flowing full or slack flow, accelerate to be upwards entrained with acid mist foam by the pipe end to last volume gas or gas, diluted acid bubble shortens pipeline, pump housing life-span.
3, when upper acid amount is excessive, impulse force makes liquid wave rolling in groove, causes upflow tube part flowing full, part slack flow, and even acid solution is directly overflowed in groove; Overflow port divides sour flow velocity slow, easily in knot acid dirt resistance hole, overflow mouth of pipe place.
4, old-fashioned pipe-type acid distributor be with large caliber divide acid, account for that tower tangent plane is large, few tower height of layouting, filler have relatively high expectations, main, arm is used with, obviously pre-system of distribution is not set, cause the long and short gap of arm larger, overpressure skewness, central section and border area point flow velocity difference are bigger than normal, are prone to the resistance hole of part weak current speed after the life-time service of border area.
Summary of the invention
The purpose of this utility model is to provide one and produces Si road supervisor's pipe-type high-efficiency acid trap for vitriol oil relieving haperacidity, and it is rational in infrastructure, safe and reliable to operation, long service life, and cost performance is high.
The technical solution of the utility model is: mainly by a point acid supervisor, some points of sour arms and pants shape are divided sour arm, sour arm is divided in blind area, divide sour equalizing line, the pre-elbow distributing, the pre-four-way distributing, the pre-taper(ed)pipe distributing, six of pre-distribution is led to, the pre-straight tube composition distributing, acid trap is circular, four tunnels divide acid supervisor Parallel Symmetric to be arranged in circular face, four tunnels divide the longitudinal symmetrical two ends of acid supervisor to connect respectively the elbow of pre-distribution, the two-way of the right and left of two symmetries divides the pre-distribution elbow on acid supervisor to be connected with the middle pre-four-way distributing, the four-way of symmetrical pre-distribution again with the taper(ed)pipe of lateral symmetry, pre-six siphunculus that distribute connect, between pre-six siphunculus that distribute, connecting again a pre-straight tube distributing, six siphunculus of the pre-distribution of lateral symmetry, pre-distribution straight tube with longitudinal both sides symmetry, the pre-elbow distributing connects, two pre-elbows that distribute of six logical connections suitable for reading of the pre-distribution of lateral symmetry, this elbow connects the pre-six logical flange-interfaces that distribute, some points of sour arms, blind areas divide sour arm, border area pants shape to divide sour arm to be vertically connected to point acid supervisor's both sides with flange, point sour equalizing line is symmetricly set on the two ends between point acid supervisor, is connected to point acid supervisor above perpendicular to point acid supervisor and with flange, and sour arm is parallel with dividing.
The utility model has the following advantages compared with the prior art:
1, owing to having designed pre-system of distribution and point sour equalizing line, limited the length of point sour arm, balanced flow velocity, the flow of point, has solved point acid point border area because of the resistance hole that weak current speed is former thereby cause.
2, voidage 60% left and right, without vortex resistance, flue gas speedup is few, has reduced acid mist entrainment at the pipe end, makes specific absorption improve get Geng Gao, and dry moisture is lower, has saved the energy.
3, divide acid point many, evenly, non-blind area, has eliminated point sour dead angle and gas-liquid loose contact phenomenon, effectively reduces tower body height, packed height and construction costs in point acid.
5, can ensure acid amount flowing full, steadily, not pantothenic acid and produce sour foam, has stopped the volume band of gas and has gone out sour foam and diluted acid bubble, makes the life-span of the pump housing and pipeline longer in point acid.
The utility model is a kind of vitriol oil relieving haperacidity acid trap of efficient, high anti-corrosion and Ultra Low Cost, extend the work-ing life of acid trap, ensured acid making system normal operation and maintenance the good production environment in workshop, be the brand-new more environmental protection of the 4th generation after stainless steel tube slot type, energy-conservation novel acid separating device.
