Description
Technical Field
The utility model belongs to the improvement of coke-oven plant desulfurizing tower spray gun belt cleaning device structure, especially a desulfurizing tower spray nozzle belt cleaning device.
Background
The existing 2 desulfurization towers of the coking branch plant adopt an HPF desulfurization method, the desulfurization tower adopts a tower-type desulfurization tower structure, and a regeneration section is arranged at the top of the desulfurization tower. The production flow comprises the following steps: the desulfurization circulating liquid firstly enters a regeneration section at the top of the desulfurization tower through a desulfurization circulating pump, sulfur in the circulating liquid is reduced into elemental sulfur in the regeneration section under the action of air pressure and a catalyst, the elemental sulfur overflows into a foam tank and is extracted through a sulfur melting vat, and the reduced desulfurization liquid enters a lower coal gas desulfurization section through an overflow pipe to perform coal gas desulfurization again.
The regeneration section at the top of the desulfurization tower uses the pressure generated by the circulating pump to enter the circulating pipe, and forms mixed liquid to enter the regeneration section after air is pumped through the venturi. In the operation process, the circulating liquid contains the monomer sulfur, and after the monomer sulfur enters the venturi spray gun, if the flow and the pressure are not well controlled, the spray gun is easy to be blocked. The amount of air pumped in is insufficient, which directly affects the reduction reaction in the circulating liquid and finally causes unqualified sulfur-containing gas.
The problem that present desulfurizing tower shower nozzle exists:
1) the most of the 32 spray guns on the annular pipe of the regeneration section of the top of the desulfurization tower are provided with more than one circulating pump
All are blocked. Resulting in high circulating pump pressure but a reduced circulating liquid flow rate to the regeneration section.
2) Because the spray gun is blocked, the circulating liquid is blocked when entering the regeneration section, the circulating liquid enters the air extraction pipeline and cannot be sprayed, the amount of air sucked is insufficient, and elemental sulfur in the desulfurization liquid cannot be reduced in time.
3) Because the length of the spray gun is 6 meters and the height of the desulfurizing tower is 40 meters at the top of the desulfurizing tower, a 100-ton crane is used to lift the spray gun out for cleaning one spray gun in the past, but the crane has long service time and high cost. A crane is typically used for nearly a week. The method cannot be adopted on the premise of reducing the cost.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a desulfurizing tower shower nozzle belt cleaning device, its simple structure is reasonable, and the dependable performance effectively clears up the sulphur cream in the tie coat that the shower nozzle inner wall formed, prevents that the sulphur cream from blockking up the shower nozzle, reduces the clearance expense, reduces cost of maintenance, improve equipment essence safety and send out coal gas desulfurization effect outward.
The purpose of the utility model is realized like this: the utility model provides a desulfurizing tower shower nozzle belt cleaning device, include that the equipartition is setting up the spray gun on the ring pipe of desulfurizing tower top regeneration section, 6 meters long body is being connected to the lower part of spray gun shower nozzle, shower nozzle belt cleaning device's structure is setting up the shrouding that has central screw for the front end of tubulose seat, the front end of cleaning head at tubulose seat through threaded connection, set up on the pipe wall of its rear end both sides, the shaft hole of symmetry down, articulated seat is being connected firmly to the front end of tubulose pole, the hinge hole of articulated seat is corresponding with the shaft hole of tubulose seat rear end, and make the front end of tubulose seat hinge at the tubulose pole through the round pin axle, shower nozzle belt cleaning device's external diameter is less.
The utility model discloses a theory of operation:
the utility model discloses demolish former shower nozzle of desulfurizing tower, the freely movable joint that utilizes to make please wash, makes a round trip to draw in shower nozzle lower part pipeline and erodees, makes the sulphur plaster mud that glues on the straight-flow pipe in shower nozzle lower part throw off with the pipe wall to make the shower nozzle spraying volume reply former design ability, improve the sulphur plaster volume in the desulfurizing tower separation coal gas, reach the coal gas and contain sulphur and reach national standard.
The utility model has the advantages of simple and reasonable structure, the dependable performance has realized effectively clearing up the tie coat that the sulfur cream formed at the shower nozzle inner wall, has prevented that the sulfur cream from blockking up the shower nozzle, has reduced the clearance expense, has reduced cost of maintenance, has improved equipment essence safety and has sent the coal gas desulfurization effect outward.
Drawings
The present invention will be further described with reference to the accompanying drawings, and fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
