In the preferred scheme, the bottom of the sewage collecting tank is provided with a thermal resistor, and the thermal resistor is vertically inserted into the heat of the sewage and is used for measuring the temperature of the sewage.
This patent can reach following beneficial effect:
liquid ammonia tank exhaust blowdown liquid enters into blowdown liquid collecting tank, has dissolved ammonia in the blowdown liquid, and steam heating pipe has improved the temperature of blowdown liquid, and then has improved the speed of volatilizing of ammonia, and the ammonia that volatilizees out passes through ammonia recovery pipeline and retrieves. In order to further improve the volatilization speed of the ammonia gas, a stirring device is added, and the stirring blade rotates to drive the exhaust liquid to stir, so that the ammonia gas recovery speed is further improved. The utility model discloses can retrieve the ammonia that contains in the blowdown liquid, help the recycle of ammonia, reduce the subsequent processing cost of blowdown liquid.
Drawings
The invention will be further explained with reference to the following figures and examples:
fig. 1 is a schematic structural diagram of the present invention.
In the figure: the device comprises a sewage collection tank 1, a sewage input pipe 2, an ammonia gas recovery pipeline 3, a residual liquid discharge pipe 4, a steam heating pipe 5, a motor 61, a stirring blade 62, a thermal resistor 7 and a barometer 8.
Detailed Description
The preferable scheme is as shown in fig. 1, the liquid ammonia recovery device for liquid ammonia tank sewage discharge comprises a sewage collection tank 1, wherein a sewage input pipe 2 is arranged on the side wall of the sewage collection tank 1, and the sewage collection tank 1 is used for recovering the sewage discharged by the liquid ammonia tank through the sewage input pipe 2; an ammonia gas recovery pipeline 3 is arranged at the top of the sewage liquid collecting tank 1, a residual liquid discharge pipe 4 is arranged at the bottom of the sewage liquid collecting tank 1, and a heating device is arranged in the sewage liquid collecting tank 1.
And the blowdown liquid input pipe 2, the ammonia gas recovery pipeline 3 and the residual liquid discharge pipe 4 are all provided with switch valves, and the bottom of the blowdown liquid collection tank 1 is provided with a barometer 8. This technical scheme has increased ammonia recovery unit in current liquid ammonia hydrogen manufacturing system, and blowdown liquid collecting tank 1 is used for collecting liquid ammonia tank exhaust blowdown liquid, has dissolved ammonia in the blowdown liquid, improves the temperature of blowdown liquid through heating device, has improved the speed of volatilizing of ammonia, and the ammonia of volatilizing passes through ammonia recovery pipeline 3 and retrieves.
Further, the heating device is a steam heating pipe 5, and steam is introduced into the steam heating pipe 5. Because steam is a common heat source in a glass manufacturing plant area, the technical scheme adopts steam heating, and the steam can be introduced from the existing steam source without adopting electric heating, thereby saving energy and reducing cost.
Furthermore, a plurality of heating sheets are arranged on the steam heating pipe 5. The heating plate is a round radiating fin, which is beneficial to rapid heat dissipation.
Further, a stirring device is arranged in the sewage collecting tank 1 and is used for stirring the sewage. The stirring device can accelerate the movement of liquid and is beneficial to the rapid volatilization of ammonia gas. The stirring device is specifically as follows: including setting up motor 61 in 1 lateral wall lower part of blowdown liquid holding tank, motor 61 drive axis of rotation rotates, the axis of rotation on be equipped with a plurality of stirring vane 62.
