Description
Technical field
The utility model relates to a kind of device of clearing up brown iron oxide in acid regeneration gelled acid pipeline, reduces iron oxide and exceptionally arranges, and belongs to cold rolling acid regeneration equipment technical field.
Background technology
In cold rolling acid regeneration production process, carry out periodic inspection to the equipment of acid regeneration unit, during maintenance, need to carry out sour water conversion operations to roaster, and also will carry out sour water conversion operations to roaster in the situations such as spent acid quantity not sufficient.During sour water conversion operations, the iron content concentrated acid in equipment is diluted to prevent acid solution crystallization, and then switch to pure water operation or shut down; the brown iron oxide particle that dilution concentrated acid produces is minimum; be not easy to be washed, in the waste gas of smoke stack emission, contain a large amount of iron oxide dusts, contaminated environment.In acid operation handoff procedure, sour water conversion can cause the crystallization of iron content concentrated acid, and crystal is attached to inner-walls of duct, and easily plug nozzle and pipeline, must change spray gun, not only affected normal production, also improved production cost.
Utility model content
Technical problem to be solved in the utility model is to provide the device of brown iron oxide in a kind of Automatic clearance acid regeneration gelled acid pipeline, this device can be removed the ducted foreign material of acid regeneration gelled acid, avoid plug nozzle and pipeline, also avoid containing a large amount of iron oxide dust contaminated environment in the waste gas of smoke stack emission.
The technical scheme solving the problems of the technologies described above is:
The device of brown iron oxide in a kind of Automatic clearance acid regeneration gelled acid pipeline, it comprises spray gun, venturi scrubber, spent acid tank, spent acid tank, venturi scrubber and spray gun are connected successively, its improvements are, it has increased water storage tank, water pump and filter, water storage tank is connected with spray gun entrance by water supply line, water pump is arranged in water supply line, water supply line and spray gun junction are provided with water supply valve, between spent acid tank and spray gun, install return additional, filter is arranged in return, and return and spray gun junction are provided with valve.
The device of brown iron oxide in above-mentioned Automatic clearance acid regeneration gelled acid pipeline, the valve that install described return and spray gun junction is acid inlet valve door and return valve, the front end of acid inlet valve door connects spray gun inlet pipeline, its rear end is connected with front end, the venturi scrubber conveyance conduit of return valve respectively, and the rear end of return valve is connected with filter pipeline.
Usefulness of the present utility model is:
The utility model has increased water storage tank and water supply line at spray-gun water-feeding mouth place, make in sour water transfer process, the liquid of lance ejection is desalted water or washings, solves the thing generation that produces brown iron oxide in roaster at all, thereby guarantees not contain brown iron oxide in outer last person's gas.The utility model utilizes gelled acid temperature high simultaneously, and the feature that density is large is gelled acid circulating reflux by increasing filter and return, takes dregs crystal in pipeline and silicon mud out of pipeline, reduces and turns spray gun clogging in sour process.
The utility model has solved the sour spray nozzle clogging phenomenon that turns spray gun in water process, save the time of changing spray gun, reduced production cost, improved benefit, simultaneously acid behaviour turns water behaviour and can reduce significantly in chimney exhaust gas and contain brown iron oxide, has avoided the pollution to environment.The utility model is simple in structure, easy to operate, respond well, is worth applying in the industry.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure, mark is as follows: spray gun 1, venturi scrubber 2, spent acid tank 3, filter 4, water pump 5, water storage tank 6, water supply valve 7, acid inlet valve door 8, return valve 9, water supply line 10, return 11.
The specific embodiment
The utility model comprises spray gun 1, venturi scrubber 2, spent acid tank 3, filter 4, water pump 5, water storage tank 6, water supply valve 7, acid inlet valve door 8, return valve 9.
In figure, show, spray gun 1, venturi scrubber 2, spent acid tank 3 are acid regeneration equipment of the prior art, and spent acid tank 3, venturi scrubber 2 and spray gun 1 are connected successively, under the normal condition of production, acid inlet valve door 8 is opened, and the spent acid of spent acid tank 3 enters spray gun 1 by venturi scrubber 2.
In figure, show, import department at spray gun 1 has increased water storage tank 6 and water pump 5, water storage tank 6 is connected with spray gun 1 entrance by water supply line 10, water pump 5 is arranged in water supply line 10, water supply line 10 is provided with water supply valve 7 with spray gun 1 junction, when water supply valve 7 is opened, water storage tank 6 supplies water to spray gun 1 by water pump 5.
In figure, show, between spent acid tank 3 and spray gun 1, install return 11 additional, filter 4 is arranged in return 11, return 11 is installed into sour valve 8 and return valve 9 with spray gun 1 junction, the front end of acid inlet valve door 8 connects spray gun 1 inlet pipeline, its rear end is connected with front end, venturi scrubber 2 conveyance conduits of return valve 9 respectively, and the rear end of return valve 9 is connected with filter 4 pipelines.
