Abstract
The invention provides a sieve-plate tower liquid distributor which is arranged between an upper tower plate and a lower tower plate and welded and fixed with a cylinder body, wherein the sieve-plate tower liquid distributor comprises an inlet pipe and a distribution groove, and the inlet pipe is arranged in the distributing groove. Compared with the prior art, the invention has the advantages of reducing the design height of the whole tower, optimizing the stability of materials in the tower, being helpful to improve the separating efficiency of a high rectifying tower and avoiding extraction liquid air enclosure.
Description
Technical field
The present invention relates to a kind of sieve-plate tower liquid distribution trough, especially a kind of sieve-plate tower liquid distribution trough of double overflow.
Background technology
Along with world technology and rapid economic development, all trades and professions suddenly increase oxygen, nitrogen, argon demand, and consumption is increasing, impels air separation plant to make bigger and bigger, and technological process is more and more.
The characteristics of air separation plant are both at home and abroad at present: hugeization, molecular sieve purification, supercharging air turbo-expander, packed tower, full rectifying hydrogen-free argon producing, interior compression, gas-liquid and product, varying duty, multi-state, high-purity, high extraction, high automation, high reliability, low energy consumption, operation long period etc.
And require extra high petrochemical industry and fluid product amount to require many especially users to oxygen nitrogen product pressure, always have the requirement of compression process air separation plant in selecting.In recent years, compression process was also more and more universal in the metallurgy type air separation plant adopted.Interior compression process comprises following advantage:
1. liquid oxygen pump+supercharging air unit has substituted the saturating compressor bank of oxygen, and power consumption reduces;
2. the spare parts and components of liquid oxygen pump+supercharging air unit is lower than the price of the saturating compressor bank of oxygen, makes the maintaining cost low;
3. after liquid oxygen pump+supercharging air unit has substituted the saturating compressor bank of oxygen, no High Temperature Gas oxygen, security is better, and device is stable more reliable;
4. the supercharging air unit has the possibility that unites two into one with air compressor unit, makes to take up an area of to lack, and easy to operate, control is convenient;
5. the easier adjusting of the saturating compressor bank of oxygen pressure ratio oxygen of liquid oxygen pump.
Interior compression process air separation plant is in flowsheeting optimization is calculated, from the angle that cuts down the consumption of energy, reduce the pressure at expulsion of supercharger as far as possible or reduce the pressurized air flow, guarantee the minimum temperature difference of main heat exchanger simultaneously, yet, the gas phase ratio is sometimes up to 25% after the throttling of high pressure liquid air, the gas phase ratio is high more after the throttling of high pressure liquid air, when caliber constant in the also corresponding raising of ducted flow velocity, the high more easy more liquid distribution inequality that causes of gas phase ratio after the throttling of tower liquid air under advancing, the empty gas enclosure of drawing liquid is unfavorable for the rectifying of rectifying column in might causing simultaneously.Slotted disc type gas-liquid distributor, tubular liquid distributor, shower nozzle distributor etc. are because of its complex structure, and will waste certain design height, so inapplicable double overflow sieve-plate tower.
Summary of the invention
At the deficiencies in the prior art, the technical problem that the present invention solves provides the simple sieve-plate tower liquid distribution trough of a kind of manufacturing, and this sieve-plate tower liquid distribution trough can make gas or liquid can be evenly distributed and avoid the influence of gas flow to the tower tray liquid level in lower height.
Purpose of the present invention realizes by following technical scheme is provided:
A kind of sieve-plate tower liquid distribution trough is installed on up and down between two blocks of column plates, and fixing with the cylindrical shell welding, and wherein, described sieve-plate tower liquid distribution trough comprises an inlet tube and a distributing slot, and described inlet tube is installed in the described distributing slot.
As a further improvement on the present invention, described column plate connection one is used to guarantee the carrying bolt of described column plate installation back levelness.
As a further improvement on the present invention, described inlet tube comprises pipe cap, distributor pipe and adapter.
As a further improvement on the present invention, described adapter and cylindrical shell welding.
As a further improvement on the present invention, described distributing slot comprises connecting plate and hole slot.
As a further improvement on the present invention, an end of described distributing slot is by described connecting plate and the welding of described cylindrical shell, and an end is by described hole slot and the welding of described cylindrical shell.
As a further improvement on the present invention, be provided with the spray apertures of even layout in the described hole slot.
As a further improvement on the present invention, have passage and liquid-leaking nozzle on the described inlet tube.
Beneficial effect of the present invention is mainly reflected in: reduce whole tower design height, optimize logistics in the tower stability, help to improve the rectifying column separative efficiency, the empty gas enclosure of drawing liquid in avoiding simultaneously.
