When the mixed liquor falls to the top of the water baffle 11, the side face of the water guide plate 9 and the two ends of the water baffle 11 are attached to the inner side of the lower tower body 1, hot steam continuously rises along the steam hole 10, the mixed liquor is distilled while the mixed liquor is prevented from flowing down from the steam hole 10, the mixed liquor can only flow down along the gap between one side of the water baffle 11 and the lower tower body 1, so that the residence time of the mixed liquor on the water baffle 11 is prolonged, the distillation effect of the hot steam in the downward flowing process of the mixed liquor is improved, and the separation effect of the mixed liquor is improved.
The working principle of the invention is as follows:
firstly, hot steam is fed into the lower tower body 1 through a steam inlet pipe 8, then the mixed liquor is fed into the upper tower body 2 through a liquid inlet pipe 4, the mixed liquor falls down under the action of gravity and falls on a water guide plate 9 at the uppermost part, the hot steam moves upwards through a steam hole 10, so that the mixed liquor on the water guide plate 9 is heated, low-volatility liquid in the mixed liquor boils and is vaporized and discharged from a steam discharge pipe 3, the mixed liquor continuously flows downwards along a gap between a water baffle plate 11 and the inner wall of the lower tower body 1 and falls on the next water guide plate 9 to continue distillation and vaporization, and finally flows to the bottom in the lower tower body 1 to finish the first step of distillation, then the upper tower body 2 moves downwards along the inner part of the lower tower body 1 through the action of a pushing mechanism, the liquid inlet pipe 4 is not blocked in the process of moving downwards through a first yield groove 5, in the downward moving process of the upper tower body 2, the space between the upper tower body 2 and the lower tower body 1 is reduced, so that the rising height of hot steam in the upper tower body 2 and the lower tower body 1 is reduced, the cooling speed of the hot steam is reduced, in the downward moving process of the upper tower body 2, the upper tower body 2 extrudes the water baffle 11 above, under the action of the elastic supporting mechanism, the water guide plates 9 are synchronously moved downwards, the steam guide mechanism connected to the water guide plate 9 at the bottom gradually communicates with the steam inlet pipe 8 along with the downward movement of the water guide plate 9, and therefore, the steam is led into the accumulated liquid at the bottom in the lower tower body 1 through the steam guide mechanism to carry out reheating distillation on the distilled accumulated liquid, the residual low-volatility liquid in the accumulated liquid is reduced, the separation effect of the mixed liquid is improved, and the distillation efficiency is improved.
The foregoing has shown and described the basic principles, principal features and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the foregoing embodiments, but rather, the foregoing embodiments and description illustrate the principles of the invention, and that various changes and modifications may be effected therein without departing from the spirit and scope of the invention as defined by the appended claims and their equivalents.
