Abstract
The utility model discloses an absorption tower with an internal circulation device. The absorption tower with the internal circulation device comprises an absorption tower and a spraying device, wherein an air inlet end and an air outlet end are arranged on the absorption tower; the air inlet end is connected with a final cooled coal gas pipeline; the air outlet end is connected with a coal gas user; the spraying device comprises a spraying pump; a water inlet end of the spraying pump is connected with the absorption tower; a water outlet end of the spraying pump is connected with each branch spraying pipeline through a three-way pipeline; the tail end of each branch spraying pipeline stretches into the absorption tower; a nozzle is arranged at the tail end of each branch spraying pipeline which stretches into the absorption tower; a switch regulating valve is arranged on each spraying pipeline; the nozzles are corrosion-resistant. An internal circulation mode is increased, the spraying amount of absorption liquid is increased, a contact area is effectively enlarged, the mass transfer impellent is improved, and the content of gas passing through the absorption tower is reduced. The device is stable to operate and high in product recovery rate and has high economic benefits and environment-friendly benefits.
Description
Technical field
The utility model relates to a kind of absorption tower, specifically a kind of absorption tower with internal circulation apparatus.
Background technology
In chemical industry, often need each component in admixture of gas is in addition separated, utility or remove harmful substance in mist in gas recovery mixture, in order to avoid atmosphere pollution.During absorption operation, due to the change of actual production throughput, mass transfer area is constant, causes organic efficiency to reduce, and outlet content increases, and causes waste and contaminated environment.
Generally, the gas access condition on absorption tower is determined by last operation, can not arbitrarily change.Therefore, the regulating measure of absorption tower when operation can only change the condition of absorbent.The condition of absorbent comprises flow rate L, temperature T, content x three elements.General absorption operation has optimal absorption temperature, and operating flexibility is very little, and import content X is generally controlled at reduced levels, and operating flexibility is also smaller comparatively speaking.Improve absorbent flow and can increase absorption driving force, improve mass transfer force, operating flexibility is large.This just need to effectively increase contact area by increasing interior circulation to reach the improvement to operating condition, improves mass transfer force, to reduce gas content behind absorption tower.
For above-mentioned situation, the utility model has been made corresponding improvement for promoting the effective separation of the gas in absorption tower.
Utility model content
The problem that the utility model solves has been to provide a kind of absorption tower with internal circulation apparatus, and this utility model, by circulation in increasing, has improved sprinkling amount, has reached the object that strengthens Gas-Liquid Absorption mass-transfer efficiency.
For solving the problems of the technologies described above, a kind of absorption tower with internal circulation apparatus of the utility model, comprises absorption tower and flusher, is provided with inlet end and outlet side on described absorption tower, described inlet end connects whole cooled coal gas pipeline, and described outlet side is connected in coal gas user; Described flusher comprises spray pump, the water inlet end of described spray pump connects absorption tower, the water side of spray pump connects each branch by triplate line and sprays pipeline, the end that pipeline sprays in described each branch stretches in absorption tower, and the end that stretches into absorption tower Nei Ge branch sprinkling pipeline is respectively arranged with shower nozzle.
Described respectively sprinkling is respectively arranged with regulating switch valve on pipeline.
Described shower nozzle is corrosion-resistant shower nozzle.
The beneficial effects of the utility model are:
1, the utility model, by original single tower absorption equipment is transformed, utilizes and increases interior circulation, has improved the mode of sprinkling amount, effectively increases contact area, improves mass transfer force, has reduced gas content behind absorption tower.
2, this utility model transformation is convenient, stable, changes product recovery rate high, has good economic benefit and environmental benefit.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure: 1-absorption tower, 11-inlet end, 12-outlet side, 2-flusher, 21-spray pump, the whole cooled coal gas pipeline of 3-, 4-coal gas user, pipeline, 61-shower nozzle, 62-regulating switch valve spray in 5-triplate line ，6-branch.
The specific embodiment
For clearly demonstrating technical characterstic of the present utility model, below by a specific embodiment, and in conjunction with its accompanying drawing, this programme is set forth.
As shown in Figure 1, a kind of absorption tower with internal circulation apparatus of the utility model, it comprises absorption tower 1 and flusher 2, is provided with inlet end 11 and outlet side 12 on described absorption tower 1, described inlet end 11 connects whole cooled coal gas pipeline 3, and described outlet side 12 is connected in coal gas user 4; Described flusher 2 comprises spray pump 21, the water inlet end of described spray pump 21 connects absorption tower 1, the water side of spray pump 21 connects each branch by triplate line 5 and sprays pipeline 6, the end that pipeline 6 sprays in described each branch stretches in absorption tower 1, and the end that stretches into absorption tower 1 Nei Ge branch sprinkling pipeline 6 is respectively arranged with shower nozzle 61.
Described respectively sprinkling is respectively arranged with regulating switch valve 62 on pipeline 6.Regulating switch valve 62 can be adjusted the size of the interior shower nozzle 61 sprinkling amounts in absorption tower 1 as required.
Described shower nozzle 61 is corrosion-resistant shower nozzle.Corrosion-resistant shower nozzle can effectively be avoided some corrosive gases or the liquid corrosion shower nozzle in absorption tower 1, affects the service life of shower nozzle.
During use, the whole cooled coal gas that carries other gases enters in absorption tower 1 along whole cooled coal gas pipeline 3, meanwhile spray pump 21 is started working, the liquid that partially absorbs in absorption tower 1 enters sprinkling pipeline 6 under the effect of spray pump 21, and shower nozzle 61 ejections that arrange from spraying pipeline 6 ends, the position of shower nozzle 61 can be arranged at different positions according to the interior concrete distribution situation in absorption tower 1, to reach even sprinkling, efficient absorption object.By this improvement, can increase in absorption tower by 1 interior circulation, improve flushing liquor flow, increase gas-liquid contact time, improve mass transfer force, further reduce gas recovery content after tower.
Except the technical characterictic described in description, be the known technology of those skilled in the art.
