Abstract
The invention relates to a concentrating tower, particularly a hydrogen sulfide concentrating tower. The hydrogen sulfide concentrating tower is divided into two towers arranged in parallel (a crude extraction tower and a fine extraction tower), wherein the crude extraction tower is divided into a first crude extraction part and a second crude extraction part, between which a partition is arranged; the first crude extraction part is provided with a gas inlet; the top of the crude extraction part is provided with a carbon dioxide outlet; a second fine extraction part is provided with a gas outlet and a carbon dioxide outlet; a first fine extraction part and the second fine extraction part are provided with a methanol inlet; the bottom of the fine extraction tower is provided with a methanol recovery pipeline; a central gas pipeline is arranged between the crude extraction tower and fine extraction tower; and the partition has a through hole structure. The technical scheme provided by the invention overcomes the defects of larger height and difficulty in repair in the traditional concentrating tower which uses one tower body for crude extraction and fine extraction, and creatively divides the crude extraction and fine extraction into the first part and the second part; and the hydrogen sulfide concentrating tower is provided with the partition, and gas can pass through holes in the partition, thereby being beneficial to enhancing the extraction efficiency and saving the material and energy.
Description
Technical field
The present invention relates to a kind of upgrading tower, especially hydrogen sulphide concentration tower.
Background technology
In prior art, hydrogen sulphide concentration tower is mostly very high, and slightly carrying the essence portion of carrying of portion is upper and lower relation arrangement, and be unfavorable for that gas reaction is complete, efficiency is low, and the gas concentration of output is incomplete.Because gas temperature can change in concentration process, the temperature difference is comparatively large, and tower body welding portion easily occurs crack, affects production safety.
Summary of the invention
Problem to be solved: for above problem, the hydrogen sulphide concentration tower providing a kind of thick stripper essence stripper of lateral distribution to separate, has efficiency high, long service life, the feature of easy-maintaining.
Technical scheme
A kind of hydrogen sulphide concentration tower, is divided into two groups of towers of parallel placement, thick stripper and smart stripper, and described thick stripper is divided into slightly carries one and slightly carry two, and centre has dividing plate; Described slightly carry one and be provided with gas feed, described thick stripper overhead is provided with carbon dioxide outlet; Described slightly carry one and slightly carry two and be provided with methyl alcohol import; Methanol Recovery pipeline is provided with bottom described thick stripper; Described smart stripper is divided into essence to carry one and essence carries two, and centre has dividing plate; Described essence is carried two and is provided with pneumatic outlet, and described smart stripper overhead is provided with carbon dioxide outlet; Described essence is put forward one and essence and is carried two and be provided with methyl alcohol import; Methanol Recovery pipeline is provided with bottom described smart stripper; Center gas pipeline is provided with between described thick stripper and smart stripper; Described dividing plate has through-hole structure.
Heat-insulating layer is provided with between described thick stripper and smart stripper.
Central methanol pipeline is provided with between described thick stripper and smart stripper.
Described center gas pipeline is oblique, and smart stripper junction is lower.
Beneficial effect
Technical scheme provided by the invention is hydrogen sulphide concentration tower, with conventional tower unlike, it is two parallel tower structures, overcome traditional upgrading tower slightly to carry, essence carries a tower body, highly higher, the shortcoming of maintenance difficult, is creationaryly divided into one, two by slightly carrying carrying with essence, and arranges dividing plate, hole on dividing plate can pass through gas, gas by barometric pressure effect successively through slightly carry one, slightly carry two, enter that essence carries one, essence carries two, progressive, extend gas reaction times in tower body, be conducive to improving extraction efficiency, save material and the energy.
The design of heat-insulating layer prevents the temperature difference in gas treating process from causing more greatly tower body weld to occur crackle, extends its work-ing life, ensures safety.
Central authorities' methanol pipeline is convenient slightly proposes two and the smart methyl alcohol supply carrying, especially when smart stripper and the sealing of thick stripper middle part.
Oblique center gas pipeline, smart stripper junction is lower, and gas utilizes air pressure and gravity to enter in smart stripper, carries one, essence carries and complete essence in two and put forward process in essence.
