Description
Technical Field
The invention belongs to the field of sulfur recovery technology and environmental protection, relates to a device for recovering sulfur vapor in a liquid sulfur pond used in an acid vapor oxidation recovery process in coking and petrochemical industries, and in particular relates to a liquid sulfur pond composite cover for recovering sulfur vapor.
Background
The coking and petrochemical industry in China adopts an oxidation recovery process for acid gas, and a Claus furnace or a sulfur producer is generally used for converting sulfuric acid-containing gas into sulfur simple substance for recovery. The generated liquid sulfur simple substance is drained into a liquid sulfur pool for temporary storage, the temperature of the liquid sulfur pool is generally 135-155 ℃, at the temperature, the liquid sulfur in the liquid sulfur pool is diffused into a working environment due to sulfur in vapor, sublimed sulfur and sulfur vapor evaporated during heating of heat preservation vapor, the sulfur is quickly crystallized due to temperature reduction, sulfur condensation phenomenon is serious easily above the liquid sulfur pool liquid level, on the container wall and in the pool cover, especially in the working environment, sulfur solids exist everywhere in the working place, the equipment and pipelines have strong corrosion effect, and the emptying pipeline of the original pool cover is also frequently blocked. The sulfur in the air is more serious to the respiratory tract hazard of workers, and a great amount of sulfur steam release can cause certain pollution to the surrounding environment.
Therefore, in the prior acid gas oxidation recovery process, a plurality of cement cover plates are generally used for covering the pool opening of the liquid sulfur pool, and the cement cover plates only play roles in blocking diffusion and heat preservation due to the fact that elemental sulfur is easy to sublimate and expand in a liquid state, and a large amount of sulfur vapor diffuses to generate adverse effects due to poor sealing effect: 1. corrosion to surrounding metal reactors and pipes; 2. the harm to the respiratory system of operators; 3. the vent line causes a blockage; 4. the yield of elemental sulfur is lost. By combining the problems, the sulfur in the working environment is removed, and the environmental protection problem to be solved is realized.
Disclosure of Invention
The invention aims to provide a liquid sulfur pool composite cover for removing sulfur vapor, which can effectively solve the problem of diffusion of sulfur vapor from the upper part of a liquid sulfur pool through condensation recovery, thereby effectively solving the adverse effect in the prior art.
The invention is realized by adopting the following technical scheme:
the liquid sulfur pool composite cover for recovering sulfur vapor comprises a composite cover body, wherein a cold roller rotary positioning frame is arranged in the composite cover body, a row of rotatable cold rollers are arranged on the cold roller rotary positioning frame, one end part of each cold roller is fixedly connected with a rotary gear, and the rotary gears at the end parts of all the cold rollers are connected with a cold roller rotary driving device after being connected through cold roller rotary driving chains; a cutting knife is arranged on the side surface of each cold roller on the cold roller rotary positioning frame; one end of each cold roller is provided with a cooling medium inlet hose, the other end of each cold roller is provided with a cooling medium outlet hose, and the cooling medium inlet hoses and the cooling medium outlet hoses are connected through a heat exchange spiral pipe which is positioned in the cold roller and is contacted with the inner wall of the cold roller; the cooling medium inlet hose of each cooling roller is connected in parallel with the cooling medium water supply pipe A and the low-pressure steam pipe C, and the cooling medium outlet hose of each cooling roller is connected in parallel with the cooling medium water outlet pipe B and the steam condensate water pipe D.
The principle of removing sulfur vapor by the liquid sulfur pool composite cover is that when the sulfur vapor from the liquid sulfur pool rises to the liquid sulfur pool composite cover, the sulfur vapor condenses on the surface of a cold roller with cooling medium passing through at the temperature lower than the melting point of sulfur, and after a period of condensation, a layer of crystalline sulfur is condensed on the surface of the cold roller. When the cold roller is driven to rotate at fixed time by the cold roller rotation driving device, the elemental sulfur coagulated and solidified on the surface of the cold roller is cut under the action of the cutting knife and falls back to the surface of the liquid sulfur under the action of gravity. The equipment effectively reduces the concentration of sulfur diffused to the surface of the liquid sulfur pool, recovers the sulfur therein, and effectively improves the yield of sulfur.
The composite cover body is internally provided with a plurality of cold rolls, and each cold roll is respectively provided with a cooling medium and a steam inlet and outlet. Under normal conditions, a cooling medium is introduced into the cold roller, and when abnormal conditions that the condensed sulfur on the cold roller cannot be cut occur, low-pressure steam is introduced to melt the sulfur condensed on the surface of the cold roller.
The invention solves the problem of high partial pressure of sulfur vapor in the prior Claus method liquid sulfur pool, solves the problems of pipeline blockage and the like caused by elemental sulfur, solves the problem of sulfur condensation in the working place of the liquid sulfur pool, solves the problem of sulfur loss caused by sulfur vapor condensation, and solves the problem of environmental pollution caused by sulfur vapor.
The invention has reasonable design and good practical application and popularization value.
