Detailed Description

The technical solution of the present invention will be described in detail with reference to the accompanying drawings.

The specific embodiment is as follows:

the utility model provides an energy-conserving evaporation equipment of preparation betaine salicylate, includes evaporating tower jar 1, is provided with evaporating dish 2 that is used for holding betaine salicylate solution in the inner chamber bottom of evaporating tower jar 1, is provided with blast pipe 3 at the top of evaporating tower jar 1, and the betaine salicylate solution in evaporating dish 2 carries out the evaporation crystallization in evaporating dish 2, and the steam that evaporates out just can discharge in blast pipe 3. A recoverer 4 is arranged outside the evaporation tower tank 1, the top of the recoverer 4 is connected with an exhaust pipe 3 through a steam pipeline 5, and steam in the evaporation tower tank 1 enters the recoverer 4 along the exhaust pipe 3 through the steam pipeline 5 under the action of an exhaust fan 10 and the internal pressure of the evaporation tower tank 1. The condenser 6 is arranged in the recoverer 4, because the condensation points of the water vapor and the betaine salicylate are different, the betaine salicylate is firstly condensed in the condenser 6, condensed liquid drops enter the evaporation dish 2 through the condensation pipeline 7 connected to the central position of the bottom of the recoverer 4 for evaporation and crystallization again, and because the condenser 6 only plays a role in cooling condensed vapor, any condenser capable of realizing the function can be selected for condensing the vapor.

In order to better collect condensed liquid drops, the bottom of the recoverer 4 can be set to be funnel-shaped, the condensed liquid drops enter the condensation pipeline 7 along the funnel-shaped bottom and finally flow into the evaporation dish 2, and then the recovery of the betaine salicylate is realized. The position that is higher than the exit of funnel-shaped bottom at the lower part lateral wall of recoverer 4 is provided with steam recovery pipe 8, under the effect of air exhauster 10 and evaporation tower jar 1 internal pressure through the surplus steam of condenser 6, alright enter into gas supply line 9 along steam recovery pipe 8, finally under the effect of the air exhauster 10 of being connected in gas supply line 9, the gas in the gas supply line 9 gets into secondary condenser 11 and carries out the secondary condensation in to get rid of the residual moisture in the gas, the liquid drop after the condensation of secondary condenser 11 is discharged by the delivery port 1101 that sets up in the condenser lower part. Under the action of the exhaust fan 10, the dried air after moisture removal enters the air heater 12 for heating, and is finally sent to the air bleeder 14 arranged at the bottom of the evaporating dish 2 through a hot air pipeline 13 connected to the air heater 12, and the dried hot air is released into the solution to be evaporated through the air bleeder 14 to realize the evaporative crystallization of the solution.

In order to better heat the solution in the evaporating dish 2 and improve the utilization rate of the dry hot air, the air discharging device 14 comprises an air inlet pipe 1401 and an air discharging ring 1402 uniformly distributed with air holes, two ends of the air inlet pipe 1401 are closed ends, an air inlet 1403 connected with the hot air pipe 13 is arranged at the side wall of one end of the air inlet pipe 1401, and the dry hot air enters the air inlet pipe 1401 through the air inlet 1403. Openings are symmetrically arranged on the side wall of the air inlet pipeline 1401, and an air discharge ring 1402 made of a hollow circular tube is welded and fixed with the air inlet pipeline 1401 at the opening position of the air inlet pipeline 1401, so that an air path capable of accommodating the flowing of the dry hot air is formed inside the air discharge device 14, and the dry hot air entering the air discharge device 14 is finally discharged into the solution of the evaporation dish 2 through the air holes on the air discharge ring 1402.
