Definitions
- the invention relates to a high-pressure gas scrubber for separating hydrogen sulfide from a gas containing hydrogen sulfide, for example coke oven gas, which essentially consists of a cylindrical container having at least one reaction zone, with each reaction zone introducing sodium hydroxide solution as a detergent in different concentrations in countercurrent to the gas containing hydrogen sulfide supplied from below through chimney trays and is injected from above and the cleaned gas is discharged via a fume cupboard in the upper part of the container and the enriched detergent is drawn off via the chimney fume cupboards, and that easily wettable expanded metal fittings are provided below the bottom chimney fume cupboard and between the nozzle and a chimney cupboard floor
- the invention has for its object to provide a high pressure gas scrubber or separator of hydrogen sulfide from, for example, coke oven gas, which is able to the amount of gas and its distribution in the reaction zone before and after passage through the soil improve, the pressure losses, the turbulence and edge movement as well as the contact and the residence time of the Wasclimediums with the gas with regard to a better washing out to improve as well as a general repair friendliness and also to ensure a buffer of washing liquid.
- a high pressure gas scrubber or separator of hydrogen sulfide from, for example, coke oven gas
- the object is achieved in that the chimney hood is releasably attached to a flat steel ring welded to the container wall and provided with a slope, and that the chimneys which ensure a lower pressure loss due to an enlarged cross section have a height which is superior to a safety drain arranged above the chimney hood.
- the chimney extractor base enables a substantial increase in the free gas cross section, which improves the requirements and the gas distribution.
- the washing liquid can drain if necessary due to the slope of the chimney extractor floor to avoid that when the washer is shut down Washing liquid remains on the floor.
- the necessary and necessary stabilization of the base is carried out by angles which run transversely in the washer and are welded in the direction of the slope to the container wall and on which the segments or segment plates forming the base are detachably fastened by screwing.
- the angle plates are not only a supporting structure for the segment plates, they also prevent the floor from being deformed or raised due to the gas pressure.
- the gas flows through the enlarged chimneys without major pressure losses and is specifically introduced into the reaction zone via the different cover plates on the chimneys.
- the shape and arrangement of the cover plates enable a uniform, homogeneous flow and distribution of the gas quantity in the free cross section of the washer.
- the gas velocity and gas distribution at the exit from the chimneys can be selected through the inclines and adjustable angles of the cover plates, so that with a minimal pressure loss in the chimneys the largest possible cross-section of the washer is immediately usable and also the expanded metal packages arranged above the floor.
- the cover plates in a special shape, designed as roof-like bevels, in the vicinity of the container wall prevent the gas from getting into the edges, which is unfavorable for the washing process.
- the washing medium sodium hydroxide solution is distributed into the washer via injection nozzles.
- the enriched liquid gets partly through cover plates that form channels and partly directly onto the floor segments without negatively influencing the gas flow and distribution.
- the enriched liquid is collected in the drain pocket made of sheet metal and closed on the side and up to a defined fill level on the sloping chimney flue, the drain pocket also serving as a pump template.
- the liquid is re-fed to a pump via a drain connection of the suction line and thus to the washing process. When a certain fill level is exceeded, the liquid is drained into the sump of the washer via the safety drain located above the floor.
- This arrangement forms a safety concept in order to prevent the washing liquid from rising on the floor until the chimneys emerge in the event of malfunctions or in the event of a pump failure or switchover and thus directly entering the gas path.
- the chimney fume hood in connection with the associated equipment described is so easy to maintain that it can either be completely dismantled or individual segments can be easily dismantled without having to separate welded connections.
- Figure 1 is a partial section through a reaction section of a high pressure gas washer
- Figure 2 is a partial side view in section of the high pressure gas washer shown in Figure 1.
- FIGS. 1 and 2 The partially shown in FIGS. 1 and 2 sections and in different views embodiment shows as essential components of a high pressure gas washer a chimney extractor 3 and a reaction section 2.
- a high pressure gas washer can consist of one or more reaction sections 2 arranged one above the other.
- the high-pressure gas washer in whatever version, consists of a cylindrical container 1 which, as stated, can contain one or more reaction sections 2.
- a flat steel ring 5 is welded over its circumference, on which a chimney extractor base 3 consisting of segment sheets 10 is detachably fastened by means of screws.
- the chimney extractor floor 3, as can be seen from FIG. 2, has a slope in the direction of the arrow 16 in order to allow the washing liquid to run off in a targeted manner.
- To stabilize the chimney hood 3 are provided across the container 1 in the direction of the slope and welded to the container wall 4 angle plates 11, on which the, forming the chimney hood 3 3 segment plates 10 are also removably screwed.
- the gas to be cleaned enters reaction zone 2 from below.
- the gas pressure is 6 to 8 bar.
- the gas flows through the defined floor passages into the chimneys 6, which are made of sheet metal and are rectangular.
- Cover plates 7, 8 fastened to supports 9 in different shapes are provided at the chimney outlet. Cover plates 7, 8 of this type direct the gas flow into the further reaction zone 2.
- the cover plates 7 are trough-shaped formed and have an upwardly open angle, which is to be selected such that the largest possible cross section in the reaction zone 2 can be achieved when the gas exits the chimneys 6 with a minimal pressure loss.
- the chimneys 6 arranged there have cover plates 8 which are oriented obliquely to the center of the container 1, in order in this way to avoid the gas being unfavorable for the washing process.
- the washing medium is distributed from above via injectors and expanded metal packs, not shown.
- the enriched liquid passes partly through the cover plates 7, 8 and partly directly onto the segment plates 10 without adversely affecting the gas flow and distribution.
- the enriched liquid is collected in the laterally connected drain pocket 12 up to a defined fill level 15, as shown in FIG. 2.
- the drain pocket 12 also serves as a pump supply, the liquid being supplied again via a drain connection 13 to a suction line (not shown) of a pump and thus to the washing process.
- a certain fill level 15 is exceeded, the liquid is discharged into the sump of the washer via the safety drain 14 arranged above the chimney extractor floor 3.
