Description
Technical field
The present invention relates to ammonia field of gasification, be specifically related to a kind of guanidine nitrate and lead to ammonia react liquefied ammonia waste hot air gasifying device.
Background technique
Original production guanidine nitrate leads in ammonia react process, just liquefied ammonia is put into ammonia knock out drum and carry out decompression gasification, because the liquefied ammonia words said in a fit of rage are endothermic processes, temperature in ammonia knock out drum is constantly declined, affect the gasification rate of liquefied ammonia, and cause the serious frost of ammonia knock out drum outer wall.
Summary of the invention
In order to solve foregoing invention problem, the present invention proposes a kind of guanidine nitrate and leads to ammonia react liquefied ammonia waste hot air gasifying device, improves the gasification rate of liquefied ammonia, eliminates ammonia knock out drum shell frost.
Guanidine nitrate leads to ammonia react liquefied ammonia waste hot air gasifying device, it comprises ammonia knock out drum, modulating valve, liquid ammonia gasifier, liquefied ammonia inlet tube, ammonia outlet pipe, reacting kettle jacketing steam condensate inlet tube, condensate spill over pipe, ammonia knock out drum entrance point is equipped with liquid ammonia gasifier, ammonia knock out drum and liquid ammonia gasifier intermediate duct are equipped with modulating valve, modulating valve entrance point is connected to the ammonia outlet pipe of liquid ammonia gasifier upper end, modulating valve outlet end is connected in the middle of ammonia knock out drum, liquid ammonia gasifier upper end is connected with liquefied ammonia inlet tube, liquid ammonia gasifier lower end coupled reaction still jacket steam condensed water inlet tube, in the middle of liquid ammonia gasifier, condensate spill over pipe is equipped with in side, pressure monitoring device is equipped with in ammonia knock out drum upper end, residul discharging valve is equipped with in ammonia knock out drum lower end, gas ammonia dereaction still pipe is equipped with in side, ammonia knock out drum upper end.(condensate spill over pipe ensures the constant liquid level in liquid ammonia gasifier; Design residul discharging valve below ammonia knock out drum, can timing releasing residual.)
Bypass valve is equipped with at described modulating valve two ends.(bypass valve be modulating valve malfunctioning or maintenance time standby valve.)
Described modulating valve is electric control valve, and electric control valve is connected by signaling line with pressure monitoring device.(by the monitoring of pressure monitoring device, motor regulated valve aperture can open large or turn down, making the air pressure in ammonia knock out drum reduce or raise, ensure that air pressure is constant.)
Be coil pipe in the middle of described liquid ammonia gasifier, coil pipe entrance point connects liquefied ammonia inlet tube, and coil outlets end connects ammonia outlet pipe.(design of coil pipe makes liquefied ammonia fully contact with reacting kettle jacketing steam condensate in liquid ammonia gasifier, carries out, to liquefied ammonia heating, being vaporized.)
Advantage of the present invention is simplicity of design, easy to use, liquid ammonia gasifier is equipped with in ammonia knock out drum front end, first liquefied ammonia enter the coil pipe in liquid ammonia gasifier, liquefied ammonia in coil pipe is through the heating of coil pipe external autoreaction still jacket steam condensation water residual heat, gasify, and the gas ammonia after gasification is passed in reactor by the certain pressure that modulating valve regulates, improve the gasification efficiency of liquefied ammonia, solve the frost of ammonia knock out drum shell, the air pressure that ammonia enters reactor obtains stable, utilize the heating of reacting kettle jacketing steam condensed water waste heat, play energy saving effect.
