Description

Technical Field

[0001] The present application relates to the field of hydrazine hydrate recovery, and in particular to a hydrazine hydrate recovery device in high-hydrazine wastewater. Background Art

[0002] Hydrazine hydrate, also known as hydrated ammonia, is an inorganic compound. It is a colorless, transparent, fuming liquid with a light ammonia smell. It smokes in moist air and has strong alkalinity and hygroscopicity. Under normal pressure, hydrazine can form an azeotrope with water. Liquid hydrazine hydrate exists in the form of a dimer, which is miscible with water and ethanol, and insoluble in ether and chloroform. It can corrode glass, rubber, leather, cork, etc. It decomposes into N2, NH3 and H2 at high temperatures. Hydrazine hydrate has extremely strong reducing properties and reacts violently with halogen elements, HNO3, KMnO4, etc. It can absorb CO2 in the air and produce smoke. Hydrazine hydrate and its derivatives are widely used in many industrial applications as reducing agents, antioxidants, medicines, foaming agents, etc. Hydrazine hydrate in high-hydrazine wastewater is often dehydrated with the aid of an evaporator when it is recovered.

[0003] With respect to the above-mentioned related technologies, the inventors believe that when the stirring structure of a conventional evaporator is used, since the outlet size of the evaporator is often smaller than the inner wall size of the barrel, in order to ensure that the conventional stirring structure can be taken out of the evaporator, the general stirring structure is similar to the outlet size of the reactor, which makes it difficult for the stirring structure to stir the inner wall of the evaporator barrel when in use, affecting the use effect of the evaporator.

[0004] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field.

[0021] The present application embodiment discloses a hydrazine hydrate recovery device for high-hydrazine wastewater, referring to Figure 1 - Figure 2 , including an evaporator barrel 1. When in use, waste water is poured into the barrel 1, and the top of the barrel 1 is sealed with the help of a shielding cover 2. After the barrel 1 is heated, the water vapor in the waste water is separated, and a motor 3 is installed on the top of the barrel 1. After the motor 3 is started, the barrel rotating rod 4 rotates, and the rotating rod 4 is installed at the bottom of the motor 3. The surface of the rotating rod 4 is slidably connected with a connecting frame 5, and a rotating frame 6 is rotatably installed at one end of the connecting frame 5. Several decomposition wires 7 are installed between the rotating frame 6 and the connecting frame 5. The stirring effect of the stirring structure is improved by means of the decomposition wire 7. The rotating frame 6 and the connecting frame 5 are rotatably connected to each other, so that the rotating frame 6 can be folded to facilitate the removal of the stirring structure as a whole, and one end of the rotating frame 6 can keep in contact with the inner wall of the barrel 1, which effectively improves the stirring effect of the stirring structure. After the motor 3 is started, the rotating rod 4 is driven to rotate, so that the rotating frame 6 stirs the processed material in the barrel 1.

The inner wall of the rotating ring 10 is threadedly connected to the threaded rod 9 at one end of the connecting frame 5. The rotating ring 10 is rotated to control the threaded rod 9 to slide on the inner wall of the connecting tube 8, so as to facilitate the adjustment of the angle of the rotating frame 6 and improve the stability of the rotating frame 6. A spring 11 is installed between the rotating ring 10 and the connecting frame 5. With the help of the spring 11, one end of the rotating ring 10 is pushed to avoid the situation where the threaded rod 9 loosens and causes the rotating frame 6 to deviate, thereby effectively improving the stability of the device.
