Description
Technical field
The invention belongs to machinery field, the flash tank vane type being specifically related in a kind of acetic synthesis reaction unit flows
Device.
Background technique
With growing continuously and fast for China's economic, demand of the China to organic chemicals increases increasingly, is acetic acid downstream
The development of the industries such as product such as fiber, coating, binder provides good background environment and opportunity.With our acetic acid scales
Expansion, device load promotion so that the slightly increased challenge of production of high-quality, inexpensive product.
Reaction zone includes reaction kettle and flash tank, and in the case where having catalyst and promotor, methanol and carbon monoxide exist
Acetic acid is generated in reaction kettle, high-temperature high-voltage reaction liquid enters low pressure flash chamber from reaction kettle, and material boiling point moment reduces, to send out
Raw moment flash distillation, the materials transient evaporation such as low-boiling acetic acid, iodomethane, water, into rear system zone purification, high boiling rhodium is urged
Agent and co-catalyst hydrogen iodide then return to reaction kettle in flash tank bottom, re-use, to realize two-phase laminated flow, are flashing
During, remove a large amount of reaction heat.Currently, flash distillation jar structure can only meet Design cooling load requirement, if acetic acid plant is negative
Lotus continues to lift up, and as flash tank inlet amount is increasing, at feed inlet, stress, which is concentrated, aggravates, and easily becomes catastrophic failure
Originating point, while impact damage, including board-like demister, wire mesh demister etc. are caused to internals.Therefore, it is necessary to current
Technology improves, with the generation for reducing maintenance cost He preventing accident.
Summary of the invention
In order to solve problem above, the object of the present invention is to provide a kind of flash tank current equalizers, are mounted on flash tank charging
At horn mouth, along between horn mouth panel, with flash tank cylinder cylinder panel, in shape is tangentially gradually opened, thoroughly solves import
The phenomenon that stress is concentrated increases mass-and heat-transfer area, improve gasification flash distillation rate, meet the separation of material under high load capacity,
The impact that driving initial stage pipeline liquid hammer can effectively be offset again significantly increases technological operation elasticity.
In order to achieve the goal above, scheme provided by the invention are as follows: a kind of flash tank vane type current equalizer, the flash tank
Vane type current equalizer includes upper cover plate and lower cover plate, and support plate, support plate and upper cover are equipped between the upper cover plate and lower cover plate
Composition multilayered structure is bolted between plate and lower cover plate, each layer of multilayered structure is fixed with multiple and upper cover plate
Vertical blade, the upper cover plate and lower cover plate are all 30 ° of V-type isosceles structures.
This flash tank vane type current equalizer is mounted at flash tank charging horn mouth, material is small along V-type of the invention
Head end enters, and material encounters the convex surface of arc shaped blade, effectively opens material dispersion, achievees the purpose that flow, while also improving
The area of mass-and heat-transfer, substantially increases the rate of gasification flash distillation, while reducing impact of the material to the inside of flash tank,
Reduce the cost of maintenance, moreover it is possible to reduce accident odds, 30 ° of V-type isosceles structures can guarantee the efficiency flowed.V-type
The excessive area loss that will cause blade of isosceles structural point, V-type isosceles structural point is too small and will cause and effectively cannot flow.
Further, the blade be one side protrusion, while be recessed, section be arc-shaped long tile shape structure.Arc
Structure, material impact can more efficiently separate material on blade.
Further, the circular arc opening direction of the blade and the V-type opening direction of upper cover plate are consistent.
Further, the ratio of the width of the spacing between the blade and blade is 0.9~1.1.If between blade
Spacing and blade width ratio it is excessive will cause that gap is excessive, some materials can be directly impinging the inner wall of flash tank,
The effect of stream is bad；If the width ratio of spacing and blade between blade is too small, after blade scatters material, between each other
It will cause interference, the efficiency flowed can reduce instead, and cannot efficiently use the area of blade.
The invention has the benefit that solving the phenomenon that flash tank import stress concentration, that is, increase mass-and heat-transfer face
Product improves gasification flash distillation rate, meets the separation of material under high load capacity, and can effectively offset rushing for driving initial stage pipeline liquid hammer
It hits, significantly increases technological operation elasticity.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention；
Wherein: 1, upper cover plate, 2, lower cover plate, 3, support plate, 4, bolt, 5, blade.
Specific embodiment
The present invention is illustrated in further detail below by way of specific embodiment.
Such as Fig. 1, a kind of flash tank vane type current equalizer, the flash tank vane type current equalizer includes upper cover plate 1 and lower cover
Plate 2 is equipped with support plate 3, passes through bolt between support plate 3 and upper cover plate 1 and lower cover plate 2 between the upper cover plate 1 and lower cover plate 2
4 fixed composition multilayered structures, each layer of multilayered structure are fixed with multiple blades 5 vertical with upper cover plate 1, the upper cover
Plate 1 and lower cover plate 2 are all 30 ° of V-type isosceles structures.
The blade 5 be one side protrusion, while be recessed, section be arc-shaped long tile shape structure.
The circular arc opening direction of the blade 5 and the V-type opening direction of upper cover plate 1 are consistent.
The ratio of the width of spacing and blade between the blade 5 is 0.9~1.1.
The course of work of the invention are as follows: this flash tank vane type current equalizer is mounted at flash tank charging horn mouth, object
Expect that the small head end along V-type of the invention enters, material encounters the convex surface of arc shaped blade, effectively opens material dispersion, reaches equal
The purpose of stream, while the area of mass-and heat-transfer is also improved, the rate of gasification flash distillation is substantially increased, while reducing material pair
The impact of the inside of flash tank reduces the cost of maintenance, moreover it is possible to reduce accident odds.
After this programme practices, the flash distillation amount of production of acetic acid device is promoted to 800t/h by 600t/h, meets load and mentions
Equipment service requirement after rising, flash tank good separation, rhodium catalyst and hydrogen iodide co-catalyst can return to reaction kettle in time
Stable conditions are maintained, while avoiding hydrogen iodide into rear system zone purification, is i.e. acetic acid plant zone purification content of iodine reduces, heat exchange
Device and the pipe leakage frequency are reduced, and parking maintenance number is reduced.
After this programme is implemented, during multiple device driving and parking, it is effectively offset the impact of pipeline cold material liquid hammer.
The above embodiment is merely an example for clearly illustrating the present invention, and is not to embodiment party of the invention
The restriction of formula.For those of ordinary skill in the art, other differences can also be made on the basis of the above description
The variation or variation of form.There is no necessity and possibility to exhaust all the enbodiments.And these belong to essence of the invention
The obvious changes or variations that mind is extended out are still in the protection scope of this invention.
