Description
Technical field
What the present invention relates to is a kind of Multifunctional rectifying column, a kind of function that not only can realize simultaneously tower and crude argon column, and can also save energy and reduce the cost, the reduce cost cost belongs to energy class air separation technology field.
Background technology
Along with the fast development of China's industry, the enterprises such as smelting iron and steel, petrochemical industry, Coal Chemical Industry, large chemical fertilizer sharply increase the demand of oxygen argon nitrogen, and are also increasing with gas and fluid volume, thereby drive developing towards large-scale and large of rectifying column.The tower diameter of rectifying column and highly be mutually to restrict, the increase that reduces to cause tower height of tower diameter, to cause gas-liquid skewness in the tower and the rectifying column tower diameter is excessive, and many-sided problem such as installation, manufacturing, transportation, excessive height will be had higher requirement at aspects such as Material selection, wind load, securities to ice chest, researched and developed the gas-liquid distributed architecture of various complexity for each enterprise of the problems referred to above and researcher, so not only increased gas-liquid distributed architecture manufacture difficulty, but also increased production cost, prolonged the production cycle.
At present, distribute for the gas uniform of the large tower diameter rectifying column of air separation unit and to realize by gas distributor that mainly the distribution of gas inequality not only affects the rectification effect of rectifying column, but also increase the rectifying column energy consumption.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, and provide a kind of do not need on tower extract in the situation of argon cut steam, just can realize the normal operation of crude argon column, simultaneously successful solution the upper tower argon cut steam uneven problem of distribution of gas that enters crude argon column, can also reduce the Multifunctional rectifying column of tower height, saving cost.
The objective of the invention is to finish by following technical solution, it mainly includes a rectifying column that is comprised of Shang Ta and lower tower, one crude argon column that links to each other with rectifying column, described upper tower is taken out mouthful as cut-point take the argon cut and is divided into two sections, wherein tower and described crude argon column are connected to a tower body on the hypomere, and tower on the epimere is also linked to each other with tower on the hypomere by the rising steam mouth of pipe as secondary tower; The bottom of described rectifying column is connected with tower on the hypomere by a liquid distribution trough, and tower links to each other with described liquid distribution trough by the phegma mouth of pipe on the described epimere, and the bottom of passing through tower on this liquid distribution trough and the hypomere is connected.
Described crude argon column is connected on the hypomere in the tower by a upper cone and consists of a combination tower body; The feed gas of described crude argon column is distributed as the rising steam of tower on the hypomere from distribution.
The present invention by with crude argon column as the secondary tower of tower on the hypomere and be designed to one the combination tower body, saved material, reduce cost, compare with traditional rectifying column, can greatly improve the initial distribution that argon cut steam enters into crude argon column, have the characteristics such as rational in infrastructure, stable, energy-saving and cost-reducing.
Description of drawings
Fig. 1 is the structural principle schematic diagram of prior art.
Fig. 2 is structural principle schematic diagram of the present invention.
The specific embodiment
The present invention is further illustrated below in conjunction with accompanying drawing: Fig. 1 is conventional rectification tower structure principle schematic, it comprises tower 11, crude argon column 12, the specific works process is as follows: take out mouthful extraction argon cut steam as the charging of crude argon column 12 from upper tower 11 argon cuts, the liquid of crude argon column 12 tower reactors is back in the upper tower 11 as argon cut phegma.Along with air separation plant towards large scale development, the tower diameter of rectifying column and tower height also constantly increase, the distributing homogeneity of the height of ice chest and rectifying column air inlet becomes urgent problem.
Fig. 2 is the structural principle schematic diagram of Multifunctional rectifying column of the present invention, it mainly includes a rectifying column that is comprised of Shang Ta and lower tower, one crude argon column that links to each other with rectifying column 21, described upper tower is taken out mouthful as cut-point take the argon cut and is divided into two sections, wherein tower 22 is connected to a combination tower body with described crude argon column 21 on the hypomere, and tower on the epimere 23 is also linked to each other with tower 22 on the hypomere by the rising steam mouth of pipe 24 as secondary tower; The bottom of described crude argon column 21 is connected with tower 22 on the hypomere by a liquid distribution trough 25, and tower 23 links to each other with described liquid distribution trough 25 by the phegma mouth of pipe 26 on the described epimere, and the bottom of passing through tower 22 on this liquid distribution trough 25 and the hypomere is connected.
Described crude argon column 21 is connected on the hypomere in the tower 22 by a upper cone 27 and consists of a combination tower body; The feed gas of described crude argon column 21 is distributed as the rising steam of tower 22 on the hypomere from distribution.
The specific works process is as follows: the rising steam of tower 22 bottoms and lower flowing liquid carry out heat and mass on the hypomere, tower 22 tops on hypomere (being crude argon column 21 bottoms) reach argon cut concentration, part argon cut steam enters into crude argon column 21 and participates in rectifying under the effect of pressure, another part argon cut steam enters into tower 23 sustainable participation rectifying on the epimere by the rising steam mouth of pipe 24.
The present invention does not need to extract the argon cut from upper tower, enter into crude argon column 21 after distributing again by gas distributor and carry out rectifying, but directly tower on the hypomere 22 and crude argon column 21 are connected to a tower body, so that entering into crude argon column 21, argon cut steam carries out rectifying by the certainly distribution of gas in tower body, can greatly improve the distribution situation of argon cut steam in crude argon column, improved the rectification effect of crude argon column, played energy-saving and cost-reducing effect, simultaneously the present invention will save the connecting line between tower 22 tops and two end sockets in crude argon column 21 bottoms and crude argon column 21 and upper tower on the hypomere, not only saved material, and reduced tower height, be a kind of energy-efficient, the rectifying device of economical rationality.
