Abstract
The utility model discloses a reactor for recovering sulfur in low-concentration acid gas and belongs to a sulfur recovery apparatus, which solves problems of small gas flow area, severe erosion corrosion, high equipment investment and the like of existing equipment for recovering sulfur in low-concentration acid gas. The reactor comprises a cylindrical tower, a gas inlet and a gas outlet are respectively arranged at centers of the top and the bottom of the tower, a chill distributor is inserted in the middle of the tower, a catalyst layer is arranged in the tower between the gas inlet and the chill distributor, another catalyst layer is arranged in the tower between the chill distributor and the gas outlet, and a feed inlet and a discharge outlet which are communicated with each catalyst layer are respectively arranged on upper and lower tower walls of the catalyst layer. The reactor is reasonable in structure, skillful in design, large in flow area, low in bed resistance, stable in running and low in expense of equipment, is erosion-resistant and is worthy of being popularized and applied, while the service life of catalyst is longer.
Description
Technical field
The utility model relates to a kind of sulfur recovery unit, is specifically related to a kind of reactor that reclaims the sulphur in the low concentration sour gas.
Background technology
At present, cold dish pipe heat exchanger in industrial recovery for the sulphur in low concentration (0.5～3%) sour gas is adopted mostly.The heat exchanger tube side is leaked water, the sour gas in this equipment through with the heat exchange of tube side desalted water after the steam that produces send through drum, the control steam pressure guarantees to export H with conditioned reaction device outlet temperature
2The S qualified discharge.But there are a lot of drawbacks in this equipment, and is little as gas flow area, flow velocity is bigger; The washing away of exchange heat pipe, equipment, seriously corroded; The structure of this equipment has also increased SR, has increased equipment investment, if especially the heat exchanger tube of equipment is revealed, catalyst will duck in drink, and causes catalysqt deactivation, and exhaust emissions exceeds standard, and has a strong impact on environmental quality.
Summary of the invention
The utility model is a, problem such as erosion corrosion serious, equipment investment big little for the reclaimer gas flow area that solves the sulphur in the existing low concentration sour gas, and the reactor of the sulphur in a kind of recovery low concentration sour gas is provided.
The utility model is to adopt following technical scheme to realize:
A kind of reactor that reclaims the sulphur in the low concentration sour gas comprises that top and bottom centre place offers the cylindrical tower body of air inlet and gas outlet respectively, pegs graft the cold shock distributor is installed in wherein said tower body middle part; Tower body inside between air inlet and the cold shock distributor, between cold shock distributor and the gas outlet respectively is provided with one section catalyst layer, offers charging aperture and the discharge port that communicates with it on the tower wall of every section catalyst layer upper and lower respectively.
Described cold shock distributor is formed by being in the conplane person in charge and arm, is responsible for entrance point and stretches out the tower body outside, and arm is evenly distributed on is responsible for both sides.The effect of cold shock distributor is the temperature of regulating the lower section catalyst layer, controls the reactor outlet temperature with this, makes reactor lower section catalyst layer temperature stabilization, to guarantee system outlet H
2S, SO
2Qualified discharge.
In the tower body of described air inlet bottom gas distributor is installed also, main effect is to change to enter the popular of air-flow and make the VELOCITY DISTRIBUTION of radial air flow be tending towards even; It can also make gas be diffused into uniformly and effectively in the reactant, has increased reaction contact area, and to making full use of gas, raising reaction efficiency, saving energy consumption have remarkable effect.
The utility model is compared with traditional sulfur recovery unit, and is rational in infrastructure, design is ingenious, and it is big to have circulation area, and bed resistance is little, anti-to be washed away, catalyst long service life, stable, characteristics such as cost of equipment is low, is worth of widely use.

Fig. 1 is a structural representation of the present utility model;
Fig. 2 is 4 a structural representation among Fig. 1;
Among the figure: 1-tower body, 2-air inlet, 3-gas outlet, 4-cold shock distributor, 5-catalyst layer, 6-charging aperture, 7-discharge port, 8-gas distributor, 9-are responsible for, the 10-arm.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described:
As shown in Figure 1, a kind of reactor that reclaims the sulphur in the low concentration sour gas comprises that top and bottom centre place offers the cylindrical tower body 1 of air inlet 2 and gas outlet 3 respectively, pegs graft cold shock distributor 4 is installed in wherein said tower body 1 middle part; Tower body 1 inside between air inlet 2 and the cold shock distributor 4, between cold shock distributor 4 and the gas outlet 3 respectively is provided with one section catalyst layer 5, all offers charging aperture 6 and the discharge port 7 that communicates with it on tower body 1 wall of every section catalyst layer 5 upper and lowers.
As shown in Figure 2, be the structural representation of described cold shock distributor 4, form, be responsible for entrance point and stretch out the tower body outside that arm is evenly distributed on is responsible for both sides by being in the conplane person in charge 9 and arm 10.
As shown in Figure 1, in the tower body 1 of air inlet 2 bottoms gas distributor 8 is installed also.
