Description

Flash evaporator

Technical Field

The utility model relates to a thermal technology field specifically is a flash vessel.

Background

Flashing is the phenomenon whereby saturated liquid at high pressure, after entering a vessel at a relatively low pressure, becomes a portion of the saturated vapor and liquid at the vessel pressure due to the sudden drop in pressure.

The commonly used flash evaporator comprises a barrel, a steam discharge pipe is arranged at the top end of the barrel, a liquid outlet pipe is arranged at the bottom of the barrel, and a liquid inlet pipe is arranged on the side wall of the barrel. The working principle of the flash evaporator is as follows: the high-temperature solution enters the cylinder through the liquid inlet pipe, and after entering the cylinder, the high-temperature solution and air in the cylinder generate a temperature difference and a pressure difference, so that the high-temperature solution is immediately boiled and generates a large amount of steam, the steam flashed out rises, and is finally discharged from the steam discharge pipe for other purposes. The solution in the flash evaporator has increased concentration and reduced temperature due to the escape of steam, and the solution after flash evaporation is discharged through a liquid outlet pipe and enters the next working procedure.

When the flash evaporator is used, water drops are easily condensed in the steam discharge pipe, and the water drops drop into the cylinder, so that the concentration of the solution subjected to flash evaporation in the cylinder is reduced, and the concentration of the solution cannot meet the requirement.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1 and 2, the flash evaporator of the present invention includes a barrel 10, a water receiving cover 20, a water storage tank 30, and a water guiding pipe 40.

The top of barrel 10 be provided with steam discharge pipe 11, the bottom of barrel 10 is provided with drain pipe 12, is provided with feed liquor pipe 13 on the lateral wall of barrel 10, feed liquor pipe 13 is used for inputing high temperature in the barrel 10, steam discharge pipe 11 is used for discharging the steam that produces after the flash distillation, drain pipe 12 is used for discharging the solution after the flash distillation.

The upper end and the lower end of the water receiving cover 20 are both provided with openings, the water receiving cover 20 is positioned right below the steam discharge pipe 11, and the inner diameter of the upper end surface of the water receiving cover 20 is larger than that of the steam discharge pipe 11.

The first end of the water guiding pipe 40 is connected with the lower end of the water receiving cover 20, the second end of the water guiding pipe 40 is connected with the water storage tank 30, and the first end of the water guiding pipe 40 is higher than the second end.

Thus, if water drops drop from the steam discharge pipe 11, the water receiving cover 20 can receive the water drops, and then the water receiving cover 20 transfers the water to the water storage tank 30 through the water guide pipe 40 for storage.
