[0016] The following will be combined with the drawings Figures 1-4 The specific embodiment of the utility model is further explained in detail.

[0017] Embodiment one, the technical scheme it solves is, in the use process, the digital pressure gauge 2 monitors the pressure in the venting cylinder body 1 in real time and transmits the data to the upper computer (its specific working mode uses the prior art, and the application will not be described in detail, and the upper computer is not described in the description), in order to avoid the escape of ammonia accumulated too much in the venting cylinder body 1, so a recovery pipe 3 and other components are arranged at the bottom of the venting cylinder body 1, when the ammonia in the venting cylinder accumulates to a certain extent and the pressure in the venting cylinder reaches the set value, the upper computer will control the electromagnetic valve 4 to open and start the delivery pump 5, and then the ammonia is delivered to the recovery cylinder 6 for recovery, a certain amount of water is stored in the recovery cylinder 6, and the ammonia gas mixes with the water in the recovery cylinder 6 to form ammonia water, so as to facilitate the recovery of ammonia. Further, the end cover 7 is provided with a reciprocating device 10, and the reciprocating device 10 is connected with a stirring device 12, so that under the action of the reciprocating device 10, the stirring device 12 can fully stir the solution in the cylinder body 8, so that the ammonia gas and water are fully mixed, to facilitate subsequent utilization.

[0018] Embodiment two, on the basis of embodiment one, specifically, in order to avoid the escape of ammonia accumulated too much in the venting cylinder, a digital pressure gauge 2 is arranged to monitor the pressure in the venting cylinder in real time, when the ammonia in the venting cylinder accumulates to a certain value (i.e. the pressure in the venting cylinder reaches the set value), at this time the digital pressure gauge 2 transmits this information to the upper computer, the upper computer controls the electromagnetic valve 4 to open, and starts the delivery pump 5, under the action of the delivery pump 5, the ammonia in the venting cylinder will enter the cylinder body 8 of the recovery cylinder 6 in turn through the recovery pipe 3, the delivery pump 5 and the conduit 9. A certain amount of water is added to the recovery cylinder 6 through the water inlet pipe 13, in order to facilitate the full recovery of ammonia, the lower end opening of the conduit 9 should be immersed in water, so as to facilitate the reaction of ammonia gas and water to form ammonia water, and then complete the recovery of accumulated ammonia in the venting cylinder, avoid the escape of ammonia accumulated too much in the venting cylinder.

[0019] Further, in order to facilitate the full mixing of ammonia and water in the cylinder body 8, a reciprocating device 10 and a stirring device 12 are provided. Start the first motor 19 of the reciprocating device and the second motor 22 of the stirring device 12, the first motor 19 on the support plate 15 will drive the reciprocating screw rod 16 to rotate, the reciprocating screw rod 16 will drive the mounting plate 11 through the screw sleeve 17, and the mounting plate 11 is limited by the sliding connection of the guide sleeve 18 and the vertical rod 14, so that the reciprocating screw rod 16 will drive the mounting plate 11 to move vertically along the vertical rod 14, and then the stirring device 12 on the mounting plate 11 will also move vertically.
