The embodiments described below by referring to the drawings are exemplary and intended to explain the embodiments of the present invention and are not to be construed as limiting the present invention.
As shown in fig. 1-2, an embodiment of the present invention provides a low molecular weight removal device, which comprises a housing 1, a feed liquid circulation system 2, an electric heating sieve plate 3, a condensation tank 4, a first receiving tank 5 and a vacuum receiving device 6.
The top of the shell 1 is provided with a feed inlet 11, a liquid storage cavity 12 is formed in the shell, and the bottom of the liquid storage cavity 12 is of a conical structure. Specifically, the tapered configuration causes the feed liquid to pool to the bottom of the reservoir chamber 12.
The feed liquid circulating system 2 comprises a circulating pipeline 21, a circulating pump 22 and a liquid dispersing device 23. The inlet end of the circulation pipe 21 is communicated with the bottom of the liquid storage chamber 12. The circulation pump 22 is disposed on the circulation pipe 21 and drives the liquid in the circulation pipe 21 to flow. The liquid dispersion device 23 is disposed at an output end of the circulation pipeline 21, and includes a tubular main body 231 communicated with the circulation pipeline 21 and a plurality of output pipelines 232 communicated with the tubular main body 231 and uniformly distributed. The output pipe 232 is communicated with the top of the liquid storage cavity 12.
The edge of the electric heating sieve plate 3 is fixedly connected with the wall surface of the liquid storage cavity 12, and a plurality of rows of uniformly distributed dispersion holes 31 are arranged on the surface of the electric heating sieve plate. An electric heating wire 32 is arranged between the two rows of the dispersion holes 31. Specifically, during operation, the feed liquid falls from the output pipeline 232 to the surface of the electric heating sieve plate 3, so that a liquid film is formed on the surface of the electric heating sieve plate 3, and the electric heating wire 32 generates heat, so that the temperature of the feed liquid is increased. The high-temperature feed liquid is dispersed through the dispersion holes 31, and the evaporation rate of the low-molecular compound is accelerated by increasing the contact area between the feed liquid and air.
The condensation tank 4 is integrally formed on the side wall surface of the liquid storage cavity 12, and a condensation jacket 13 corresponding to the condensation tank 4 is arranged on the shell 1. Specifically, the condensing jacket 13 is provided with a condensate inlet 131 and a condensate outlet 132. The condensate enters the condensation jacket 13 through the condensate inlet 131, exchanges heat with the low molecular compound vapor and is output from the condensate outlet 132.
The first receiving tank 5 is communicated with the bottom of the condensation tank 4. Specifically, the first receiving tank 5 is in communication with the condensation tank 4 through a pipe.
The vacuum receiving apparatus 6 includes a heat exchange condenser 61, a second receiving tank 62, a vacuum condenser 63, and a vacuum pump 64. The inlet end of the condenser 61 is communicated with the top of the liquid storage chamber 12, and the outlet end thereof is communicated with the second receiving tank 62. The output of the second receiver tank 62 communicates with the inlet end of the vacuum condenser 63. The output of the vacuum condenser 63 is in communication with the inlet of the vacuum pump 64.
When the low molecular weight removing device works, feed liquid is added into the liquid storage cavity 12 from the feed inlet 11. The feed liquid circulating system 2 works, the circulating pump 22 drives the feed liquid at the bottom of the liquid storage cavity 12 to enter the liquid dispersing device 23 through the circulating pipeline 21, and the liquid dispersing device 23 outputs the feed liquid through the plurality of output pipelines 232 to realize the dispersion of the feed liquid. The feed liquid falls onto the electric heating sieve plate 3 again, the electric heating sieve plate 3 further disperses the feed liquid and increases the temperature of the feed liquid, so that the low molecular compounds are evaporated, and the low molecular compound steam is condensed into liquid in the condensation tank 4 and stored in the first receiving tank 5. Another part of the low molecular compound vapor enters the vacuum receiving device 6 by way of vacuum pumping, and the heat exchange condenser 61 condenses the low molecular compound vapor into liquid and stores it in the second receiving tank 62. After the low-molecular removal device removes low molecules from the feed liquid, the low-molecular content is less than 0.5%, and the low-molecular content of the product is low.
In another embodiment of the present invention, the outlet of the output pipe 232 of the low molecular weight removing device is fixedly provided with an opening plate 2321. When the feed liquid is output from the output pipe 232, the perforated plate 2321 disperses the feed liquid, thereby increasing the dispersion degree of the feed liquid and accelerating the evaporation rate of the low-molecular compounds.
In another embodiment of the present invention, a plurality of vapor inlet holes 41 with downward openings are formed on one side of the condensation tank 4 of the low molecular weight removing device, which is communicated with the liquid storage chamber 12. This is provided to prevent the feed liquid from entering the condensate tank 4.
In another embodiment of the present invention, the bottom of the condensation tank 4 of the low molecular weight removal device is a conical structure. In particular, the conical structure enables a good concretization and collection of low-molecular compound liquids to said first receiving tank 5.
In another embodiment of the present invention, the bottom of the liquid storage chamber 12 of the low molecular weight removing device is provided with a heating device 121. Specifically, the heating device 121 may be an electric heating coil, which is used to heat the feed liquid to make the evaporation rate of the low molecular compound faster.
The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
