Abstract
The utility model relates to an energy saving device for evaporation and vacuum extraction in the urea production, which comprises a condenser, an ammonia condenser, and a sewer pipe and a water outlet pipe of the ammonia condenser. The utility model is characterized in that the upper end of the condenser is provided with a pipeline, and the other end of the pipeline is connected with a vacuum shut-off valve which is connected with the inlet end of a separator by a pipeline; the outlet end of the separator is connected with the sewer pipe of the ammonia condenser by a vacuum extraction pipe; a liquid exhaust opening of the separator is connected with a damaged vacuum shut-off valve which is connected with an inlet of a liquid storage tank and a damaged vacuum air guide valve; the bottom of the liquid storage tank is provided with a liquid exhaust valve. The utility model has the advantage that the utility model fully utilizes the negative pressure of cooling water level difference of the ammonia condenser in the process of the urea production to realize the vacuum extraction for an evaporation condenser.
Description
The utility model relates to a kind of energy saver, and the evaporation in particularly a kind of urea production vacuumizes energy saver.
The negative pressure of the vapo(u)rization system in the at present general urea production process mainly is to utilize vapour injection to produce negative pressure by evaporation ejector, and therefore the consumption of steam is very big in process of production.
The purpose of this utility model provides a kind of energy saver that utilizes the waterhead of ammonia condenser in the urea production process to realize negative pressure.
The technical solution of the utility model is that the evaporation in a kind of urea production of design vacuumizes energy saver, comprise condenser, ammonia condenser, ammonia condenser outfall sewer and rising pipe, it is characterized in that: one pipeline is arranged in the upper end of condenser, another termination vacuum shut off valve of pipeline, vacuum shut off valve is connect the entrance end of separator by a pipeline, the exit end of separator is connect the outfall sewer of ammonia condenser by vacuum-pumping tube, the leakage fluid dram of separator connects the vacuum breaker trip valve, the vacuum breaker trip valve also connects a container for storing liquid inlet and a vacuum breaker guide valve, one tapping valve is arranged at the container for storing liquid bottom, the upper end of separator is an exit end, there is pipe in a lower end of exit end, and there is entrance end the side of separator, and there is a cone lower end of separator, the tip of cone is a leakage fluid dram, and vacuum-pumping tube connects the upper surface of ammonia condenser outfall sewer.
The utility model has the advantages that the negative pressure of the water coolant potential difference that makes full use of ammonia condenser in the urea production process, so that vaporizer-condenser is realized vacuumizing.
Below in conjunction with accompanying drawing the utility model is elaborated,
Accompanying drawing 1 is a structural representation of the present utility model,
Accompanying drawing 2 is the separator cut-away view of the utility model figure,
Accompanying drawing 3 is the container for storing liquid cut-away view of the utility model figure,
Comprise condenser 1, ammonia condenser 2, ammonia condenser outfall sewer 3 among the figure, it is characterized in that: a pipeline 4 is arranged in the upper end of condenser 1, pipeline 4 another termination vacuum shut off valve 5, vacuum shut off valve 5 is connect the entrance end 8 of separator 7 by a pipeline 6, the exit end 9 of separator 7 is connect the outfall sewer 3 of ammonia condenser 2 by vacuum-pumping tube 10, the leakage fluid dram 11 of separator 7 connects vacuum breaker trip valve 12, vacuum breaker trip valve 12 also connects container for storing liquid 13 inlets 14 and one vacuum breaker guide valve 15, one tapping valve 16 is arranged at container for storing liquid 13 bottoms, and vacuum-pumping tube 10 connects the upper surface of ammonia condenser 2 outfall sewers 3.
When using because 3 water inlets place of ammonia condenser outfall sewer are the upper space of ammonia condenser 2, after outfall sewer 3 water inlets, because water coolant is dirty from ammonia condenser 2 rising pipes that are placed in eminence, vacuum-pumping tube 10 is formed negative pressure, and the water coolant in the ammonia condenser 2 can not pour in down a chimney, vacuum-pumping tube 10 connects the exit end 9 of separator 7, vacuumize by vacuum shut off valve 5 and 4 pairs of condensers 1 of pipeline by pipeline 6 again, with vacuumizing and the liquid that enters separator 7 from condenser 1 enters container for storing liquid 13 by the leakage fluid dram 11 of separator 7 by vacuum breaker trip valve 12, vacuum breaker trip valve 12 keeps vacuum state during work, and vacuum breaker guide valve 15 is opened will emit liquid in the container for storing liquid 13 time, destroy the negative pressure attitude of container for storing liquid 13, liquid is discharged from the tapping valve 16 of container for storing liquid 13.
