Description

Novel falling film evaporation device

Technical Field

The utility model belongs to the technical field of the grease processing equipment, concretely relates to novel falling liquid film evaporation device.

Background

The feed liquid distributor is a key part of the falling-film evaporator, and the heat exchange intensity and the production capacity of the falling-film evaporator are substantially determined by the uniform distribution degree of the feed liquid along the heat exchange tubes. By uniformly distributed is meant not only that the liquid is uniformly distributed in each tube, but also that it is uniformly distributed along the entire circumference of each tube and remains uniform throughout the length of the tube.

When the feed liquid does not uniformly wet the inner surface of all the heating tubes, the liquid-deficient or liquid-poor surfaces may become fouled by evaporation, which in turn retards the flow of the liquid film and further worsens the heat transfer conditions in the adjacent zones.

Therefore, a new type of falling film evaporation device needs to be designed.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the technical problem existing in the prior art and providing a novel falling film evaporation device to overcome the defects of the prior art.

In order to realize the purpose, the utility model relates to a novel falling film evaporation device, which comprises a cylinder body, wherein the top of the cylinder body is provided with a liquid inlet pipe and a steam outlet pipe,

the bottom of barrel is equipped with drain pipe and steam and advances the pipe, the inner chamber of barrel goes out the baffling passageway that is the S type through the horizontal partition interval, be equipped with the interval pipe of vertical setting in the inner chamber of barrel, the top and the bottom of barrel inner chamber are equipped with filter screen and lower filter screen respectively, the below of lower filter screen is established and is located steam advances the baffle of managing the top.

The utility model discloses rational in infrastructure, simple manufacture. By utilizing the cross flow process, the liquid film is not easy to scale in the heating tube, the liquidity of the liquid film is ensured, and the heat exchange effect is good.

Drawings

Fig. 1 is a schematic structural diagram of the present invention.

In the figure, 1 cylinder, 2 transverse partition plates, 3 baffling channels, 4 steam inlet pipes, 5 baffles, 6 liquid outlet pipes, 7 lower filter screens, 8 partition pipes, 9 liquid inlet pipes, 10 steam outlet pipes and 11 upper filter screens are arranged.

Detailed Description

Referring to fig. 1, the utility model relates to a novel falling film evaporation device, which comprises a cylinder body 1, a liquid inlet pipe 9 and a steam outlet pipe 10 are arranged at the top of the cylinder body 1,

the bottom of barrel 1 is equipped with drain pipe 6 and steam and advances pipe 4, the baffling passageway 3 that the inner chamber of barrel 1 is the S type is gone out through 2 intervals of transverse partition board, be equipped with the spacer tube 8 of vertical setting in the inner chamber of barrel 1, the top and the bottom of the 1 inner chamber of barrel are equipped with filter screen 11 and lower filter screen 7 respectively, the below of lower filter screen 7 is established and is located steam advances the baffle 5 of tub 4 top.

The utility model discloses rational in infrastructure, simple manufacture. The S-shaped baffling channel is used for carrying out the cross flow process, the liquid film is not easy to scale in the heating tube, the liquidity of the liquid film is ensured, and the heat exchange effect is good. The baffle can prevent the feed liquid from entering the steam inlet pipe.
