Description

Gas sweetening unit

Technical field

The utility model belongs to the environmental protection equipment field, relates to a kind of device that is used for gas sweetening.

Background technology

H in the gas ₂The removing of S has two kinds of dry method and wet methods substantially: dry desulfurization is applicable to the combustion gas that sulfur content is lower, and day output is less.This method technology is simple, and mature and reliable, cost are low, can reach higher degree of purification.But equipment is heavy when adopting this method, and labour intensity was big when also there was the replacing desulfurizing agent in the batch (-type) dry desulfurization, contaminated environment, and waste desulfurizing agent is difficult to problems such as processing.

And in the wet desulfurizing process, desulfurizing tower is the capital equipment that present sulphur is produced, and the major responsibility of desulfurizing tower is the H in the solution absorption gas phase ₂S.At present, the version of sulphur tower is more, is main with the packed tower structure how.

The problem that the filling-material structure desulfurizing tower exists is: 1, desulfuration efficiency is low, inefficiency of production; 2, desulfurizing tower is prone to stop up, and takes the whole bag of tricks to handle and all is difficult to take effect, and only takes to stop tower and unloads the filler cleaning, all can influence production and stop tower at every turn, will certainly increase investment if set up stand-by still; 3, doctor solution pipe, gas phase distributor pipe are prone to stop up, and influence the technology operation.

The utility model content

To the deficiency of prior art, the technical problem that the utility model will solve provides a kind of further raising desulfuration efficiency, avoid stopping up, stable operation, reduction process cost, simple in structure, have certain device of the gas sweetening of regulatory function automatically.

In order to solve the problems of the technologies described above, the technical scheme that the utility model provides is:

A kind of gas sweetening unit comprises tank body (8), and tank body (8) sets out gas port (1), doctor solution feed tube (2), downspout (3), holds liquid plate (4), doctor solution drain pipe (5) and air inlet pipe (6), and said holding is provided with aperture (7) on the liquid plate (4).

Said downspout (3) runs through holds liquid plate (4);

Saidly hold that liquid plate (4) horizontal multilayer in tank body (8) is arranged and adjacent liquid plate (4) distance of holding equates;

The said liquid plate (4) of holding is gone up the evenly more aperture (7) of layout number;

The absolute altitude of said downspout (3) lower end is lower than the upper end absolute altitude of its adjacent downspout in below (4);

Said air inlet pipe (6) adopts " worker " font to arrange that port is downward, can adopt the wide aperture structure, should not stop up.

But but the utility model invention has that operating cost is low, operational stability good, desulfurization effect 24 hour operation anti-clogging, a series of technical advantages such as simple in structure, non-maintaining.

The specific embodiment

Below in conjunction with accompanying drawing the utility model gas sweetening unit is elaborated.

Shown in Fig. 1-3, a kind of gas sweetening unit comprises tank body 8, and tank body 8 sets out gas port 1, doctor solution feed tube 2, downspout 3, holds liquid plate 4, doctor solution drain pipe 5 and air inlet pipe 6.Said downspout 3 runs through holds liquid plate 4; The said liquid plate 4 multilayer horizontal arrangement and adjacent in tank body 8 of holding is held liquid plate 4 distances and is equated; Said holding evenly arranged the more aperture 7 of number on the liquid plate 4; The absolute altitude of said downspout 3 lower ends is lower than the upper end absolute altitude of its adjacent downspout 4 in below; Said air inlet pipe 6 adopts " worker " font to arrange that port is downward, can adopt the wide aperture structure, should not stop up.

The process that the gas sweetening unit that uses the utility model to provide carries out desulfurization is following:

Contain H ₂The gas of S is through the hypomere of " worker " font air inlet pipe 6 even gas distributions in entering gas sweetening unit tank body; Utilize buoyant gas to be affixed on minimum liquid plate 4 lower surfaces that support; See through the aperture of holding on the liquid plate 47 and evenly mix with the doctor solution of holding between the liquid plate 4, and the H in the gas ₂S rapidly with the doctor solution H in the reduction gas that reacts ₂The content of S is according to H in the gas ₂S content is set the number of plies hold the liquid plate, and reacts through the doctor solution of holding liquid plate 4 and holding between the liquid plate of multilayer, makes H ₂The clearance of S reaches requirement, and gas up to standard is collected through gas outlet 1.

Doctor solution gets in the towers through doctor solution feed tube 3, at first holds the liquid plate in the superiors and evenly distributes and utilize gravity to see through to hold 7 of apertures on the liquid plate 4 to advance down one deck and hold liquid plate 4, the H in this process doctor solution and come-up gas ₂S reacts rapidly, reduces H in the gas ₂The content of S, the doctor solution behind the end reaction is got rid of tank body through doctor solution drain pipe 5.

When equipment normally moved, downspout 3 lower ends were in floodage, and downspout 3 upper ends are in the non-submersion state; The absolute altitude of downspout 3 lower ends is lower than the upper end absolute altitude of its adjacent downspout 4 in below; Like this can be so that surpass when holding liquid plate 4 infiltration capacities when the doctor solution that adds; When holding liquid level on the liquid plate and being higher than the absolute altitude of downspout 3 epimeres; Unnecessary doctor solution also gets into down one decks through downspout 3 and holds liquid plate 4, realizes automatic regulatory function, not only can practice thrift processing cost but also can keep removal effect.

Whole H ₂Reaction between S and the doctor solution is adopted reverse-flow, and this makes H ₂The clearance of S is higher, the doctor solution utilization rate is higher.
