Abstract
The invention 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 the absorption tower is provided with an air intake end and an air exhaust end; the air intake end is connected with a terminal cooled coal gas pipeline; the air exhaust end is connected with coal gas users; the spraying device comprises a spraying pump; the water intake end of the spraying pump is connected with the absorption tower; the water exhaust end of the spraying pump is connected with each branch spraying pipeline through three-way pipelines; the tail end of each branch spraying pipeline extends into the absorption tower; a sprayer is arranged at the tail end of each branch spraying pipeline which extends into the absorption tower; each spraying pipeline is provided with a switch regulating valve; each sprayer is of an abrasion-resistant type. According to the absorption tower, the internal circulation mode is added, the spraying quantity of absorption liquid is increased; the contact area is increased effectively; the transfer mass push force is increased; the content of gas entering the absorption tower is lowered; the device runs stably, is high in chemical product recovery rate, and has good benefits of economy and environmental protection.
Description
Technical field
The present invention relates to a kind of absorption tower, specifically a kind of absorption tower with internal circulation apparatus.
Background technology
In chemical industry, often each component in admixture of gas need be separated, utility or remove harmful substance in mist in the 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 the optimal absorption temperature, and operating flexibility is very little, and import content X generally is controlled at reduced levels, and operating flexibility is also smaller comparatively speaking.Improve the 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, with gas content behind the reduction absorption tower.
For above-mentioned situation, the present invention has made corresponding improvement for the effective separation of promoting the gas in absorption tower.
Summary of the invention
Problem solved by the invention has been to provide a kind of absorption tower with internal circulation apparatus, and this invention, by circulation in increasing, has improved the sprinkling amount, has reached the purpose that strengthens the 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 present invention, comprise 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 the 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 the sprinkling on pipeline is respectively arranged with regulating switch valve.
Described shower nozzle is corrosion-resistant shower nozzle.
The invention has the beneficial effects as follows:
1, the present invention, 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 invention transformation is convenient, stable, changes product recovery rate high, has economic benefit and environmental benefit preferably.
The accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
In figure: the 1-absorption tower, 11-inlet end, 12-outlet side, 2-flusher, the 21-spray pump, the whole cooled coal gas pipeline of 3-, 4-coal gas user, the 5-triplate line, pipeline, 61-shower nozzle, 62-regulating switch valve spray in 6-branch.
The specific embodiment
For clearly demonstrating technical characterstic of the present invention, 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 present invention, 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 each branch's sprinkling pipeline 6 in absorption tower 1 is respectively arranged with shower nozzle 61.
Described respectively the sprinkling on pipeline 6 is respectively arranged with regulating switch valve 62.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, the efficient absorption purpose.Can increase in absorption tower by 1 interior circulation by this improvement, improve the flushing liquor flow, increase gas-liquid contact time, improve mass transfer force, further reduce gas recovery content after tower.
Except the described technical characterictic of specification, be the known technology of those skilled in the art.
