| titleOfInvention | A kind of industrial urea is produced vacuum equipment instrument negative sense and is added steam unit |
| abstract | The utility model provides a kind of industrial urea production vacuum equipment instrument negative sense and adds steam unit, comprise evaporation in vacuo equipment, pressure pipeline, measuring instrument pipeline and negative sense steam pipe line, described pressure pipeline one end is connected with the top of the sidewall of evaporation in vacuo equipment, the other end is connected with negative sense steam pipe line one end, described pressure pipeline is provided with pressure point root valve, the part of described pressure pipeline between pressure point root valve to the described pressure pipeline other end is connected with described measuring instrument pipeline; The described negative sense steam pipe line other end is connected with middle pressure steam pipe and low pressure steam pipe, and described negative sense steam pipe line is provided with steam root valve, and described negative sense steam pipe line one end and described pressure pipeline other end junction are provided with one piece of restriction orifice.The utility model device, steam replaces negative sense air, and because vapor (steam) temperature is high, pressure is high, reversely flows into equipment, and urea crystallization can not occur, and solves the easy malfunctioning difficult problem of instrument instruction of evaporation in vacuo system. |
