Detailed Description
The technical solution in the embodiment of the present invention will be clearly and completely explained below with reference to the drawings in the embodiment of the present invention.
The embodiment is described with reference to fig. 1-2, and a rapid cooling negative pressure flash evaporation system comprises a flash evaporation tank 1, a hot press pump 3, a condenser 5 and a material pump 7, wherein the flash evaporation tank 1 is provided with a side wall feed inlet, a bottom discharge port and a top steam outlet, the side wall feed inlet is arranged along the tangential direction of a tank body, the bottom discharge port is connected with the material pump 7, the hot press pump 3 is provided with a steam inlet, an air suction port and a gas outlet, the top steam outlet of the flash evaporation tank 1 is connected with the air suction port of the hot press pump 3, the steam inlet of the hot press pump 3 is connected with a raw steam pipeline, and the gas outlet of the hot press pump 3 is connected with the condenser 5.
In the embodiment, a top steam outlet of a flash tank 1 is connected with an air suction port of a hot-pressing pump 3 through a first steam communicating pipe 2, the flash tank 1 is connected with the first steam communicating pipe 2 in a welding manner, the first steam communicating pipe 2 is connected with the air suction port of the hot-pressing pump 3 through a flange, a condenser 5 is provided with a steam inlet, an air outlet of the hot-pressing pump 3 is connected with the steam inlet through a second steam communicating pipe 4, the air outlet of the hot-pressing pump 3 is connected with the second steam communicating pipe 4 through a flange, the second steam communicating pipe 4 is connected with the steam inlet of the condenser 5 in a welding manner, the condenser 5 is provided with a cooling water inlet, a cooling water outlet, a condensed water outlet and a vacuum pump interface, the cooling water inlet is filled with cooling water, the cooling water outlet is used for discharging cooling water, the condensed water outlet is used for discharging condensed water, the vacuum pump interface is connected with a vacuum pump 6, the vacuum pump 6 is used for discharging non-condensable gas, a bottom discharge port is in a conical seal head form, avoiding the residue of the feed liquid. The inside cleaning ball that is provided with of flash tank ensures the cleaning performance. The flash distillation system adopts 304 stainless steel material, and the surface all satisfies food level health requirement, and the seal ring that uses all adopts food level material.
This embodiment material is tangent line flow mode entering flash tank 1's inside through flash tank 1's lateral wall feed inlet, the material can be followed a jar wall rotatory flow, flow is dispersed downwards along a jar wall to the spiral mode, the great so flash evaporation velocity of heat-transfer surface is extremely fast, the hot press pump 3 with flash tank 1 UNICOM can use raw steam to extract the inside gas of flash tank 1 as power and make the inside vacuum environment that forms of flash tank 1 simultaneously, consequently, high temperature material gets into flash tank 1 inside back moisture can flash evaporation rapidly, material temperature can reduce then flow from flash tank 1 bottom discharge gate rapidly simultaneously. The condenser 5 communicated with the air outlet of the hot-pressing pump 3 condenses and recovers the steam discharged by the hot-pressing pump 3. The time of the whole material cooling process is extremely short, the requirement can be met only within 1 second, the cooling water of the condenser 5 can be recycled, and the steam condensate can be recycled, so that the energy is saved.
The above detailed description is given to the rapid cooling negative pressure flash evaporation system provided by the present invention, and the specific examples are applied herein to explain the principle and the implementation of the present invention, and the description of the above examples is only used to help understanding the method and the core idea of the present invention; meanwhile, for the general technical personnel in the field, according to the idea of the present invention, there are changes in the specific implementation and application scope, to sum up, the content of the present specification should not be understood as the limitation of the present invention.
