Description

Oil and ammonia water separating device for nitric acid production Technical Field The utility model relates to the technical field of nitric acid production equipment, in particular to an oil and ammonia water separation device for nitric acid production. Background Nitric acid is a strong oxidizing and corrosive monobasic inorganic strong acid, is one of six inorganic strong acids, is also an important chemical raw material, and the aqueous solution of the nitric acid is commonly called nitrowater or ammonia nitrogen water, can be industrially used for preparing chemical fertilizers, pesticides, explosives, dyes and the like, and is an important nitrifying reagent in organic chemistry; The oil and ammonia water mixture is generated in the production process of nitric acid, the oil and ammonia water are required to be separated in the production process of nitric acid, at present, when the oil and ammonia water are separated in the production process of nitric acid, a distillation method is one of common separation modes, for example, in fig. 5 of the attached drawings of the specification, a schematic structural diagram of an oil and ammonia water separation device for nitric acid production in the prior art is shown, and the oil and ammonia water separation device comprises a bearing frame, wherein a supporting plate is fixedly arranged on the bearing frame, and a treatment box is fixedly arranged on the supporting plate; the treatment tank is characterized in that a feeding pipe is fixedly arranged at the top of the outer side wall of the treatment tank, a discharge port is formed in the bottom of the treatment tank, a plugging head for plugging the discharge port is detachably arranged on the treatment tank, a mounting frame is fixedly arranged on one side of a supporting plate and on the bearing frame, a condensing pipe is fixedly arranged on the mounting frame, one end of the condensing pipe is fixedly provided with a vent pipe communicated with the condensing pipe, the other end of the vent pipe is communicated with a top cover, a separating pipe is fixedly arranged on the mounting frame, the other end of the condensing pipe is communicated with the separating pipe, a heating rod is arranged in the treatment tank, when in use, an oil and ammonia water mixture is conveyed into the treatment tank through the feeding pipe, the heating rod is controlled to be started, the heating rod works to heat the oil and ammonia water mixture in the treatment tank, so that the oil and ammonia water mixture boils, ammonia water forms vapor to enter the condensing pipe through the vent pipe, the condensing pipe is in a liquid state, at the moment, gas is discharged through the top of the separating pipe, oil and the oil residues in the treatment tank are removed from the discharge port after separation, the oil and the oil residues in the treatment tank are removed from the discharge port after the treatment tank is completely plugged, realize the separation effect to oil and ammonia water mixture, separation efficiency is high, but in the actual use process, still have following defect: The oil in the oil-ammonia water mixture remains in the treatment tank to form grease, and the grease is attached to the inner wall of the treatment tank, so that the blocking of the blocking head on the discharge port is canceled, and the condition of incomplete discharge of the grease attached to the inner wall of the treatment tank is easily caused when the grease in the treatment tank is discharged, so that the discharging of the grease is not facilitated; thus, the application provides an oil and ammonia separation device for nitric acid production.
