Detailed Description
The principles and features of the present invention are described below in conjunction with fig. 1-5, with examples being provided for illustration only and not for limitation of the scope of the invention.
A waste liquid distillation device comprises a distillation cylinder 1, a connecting cylinder 2, a screening cylinder 6, a heat exchange cylinder 11 and a distributor 13.
The distillation cylinder 1 is used for containing waste liquid, and the distillation cylinder 1 comprises a cylinder body and a cylinder cover which can be mutually separated. The distillation cylinder 1 is made of a heatable material, and the liquid in the waste liquid can be heated and vaporized into gas by heating the distillation cylinder 1. The air inlet end of the connecting cylinder 2 is communicated to the top of the distillation cylinder 1, and the air outlet end of the connecting cylinder 2 is communicated with the bottom end of the screening cylinder 6. The steam generated by the distillation drum 1 passes through the connecting drum 2 and finally enters the sieving drum 6. Specifically, the connecting cylinder 2 is internally provided with a conduit 17, a guide cylinder 18 and a plurality of grate plates 3. The grid plates 3 are arranged at intervals, the grid plates 3 are provided with two circles of diversion holes 4, and the diversion holes 4 are circumferentially arranged in an array. The grate plates 3 are provided with a plurality of guide plates 5, the guide plates 5 are in one-to-one correspondence with the guide holes 4, the guide plates 5 are obliquely arranged, and the guide holes 4 in two adjacent guide plates 5 are staggered with each other, so that the air flow passing through the guide holes 4 is in a spiral shape. The guide plates 5 are respectively arranged at two sides of the grid plate 3. The guide tube 17 passes through the center of the grate plate 3, and the guide tube 18 is coaxially sleeved with the guide tube 17. On this basis, a first guide chamber 19 is formed in the duct 17, a second guide chamber 20 is formed on the outer wall of the duct 17 and the inner wall of the guide tube 18, and a third guide chamber 21 is formed on the outer wall of the guide tube 18 and the inner wall of the connecting tube 2. Wherein the conduit 17 is communicated with the distillation cylinder 1, and water vapor generated by the distillation cylinder 1 finally enters the sieving cylinder 6 after passing through the first diversion chamber 19, the second diversion chamber 20 and the third diversion chamber 21 in sequence. Steam enters the conduit 17, and the flow rate and pressure of the steam become large; the air flow is then led into a spiral by means of the grate plate 3 and enters the sieving cartridge 6 at a relatively high speed.
The bottom of the screening cylinder 6 is connected with a centrifugal wheel 7, and the centrifugal wheel 7 drives high-speed rotation through a motor 22. The steam entering the screening cylinder 6 is screened by the centrifugal wheel 7, wherein the large mass of the steam particles with solid particles can generate larger centrifugal force, so that the discrete radius of the steam particles is gradually enlarged; the vapor particles without solid particles therein have a small mass which generates a small centrifugal force and thus have a nearly constant discrete radius. The screening cartridge 6 is connected to the end remote from the connecting cartridge 2 with a screening chamber 8, said screening chamber 8 comprising a first chamber 9 in a central position and a second chamber 10 formed around the first chamber 9. The bottom of the second chamber 10 is provided with a jacking pipe 15 communicated with the screening cylinder 6, and the top of the jacking pipe 15 is provided with a cap. Due to the large mass of vapor particles with solid particles, large discrete radii, eventually enter the second chamber 10; the distributor 13 is fixed to the top of the sieving cartridge 6, the distributor 13 is connected with a plurality of spray pipes 14, the spray pipes 14 extend into the second chamber 10, and the end of the spray pipes 14 is connected with a spray head. The liquid which is atomized by the spray will re-liquefy the water vapour flowing into the second chamber 10 as liquid. A through pipe 16 is connected between the second chamber 10 and the distillation cylinder 1, and the through pipe 16 extends to the bottom of the distillation cylinder 1. The re-liquefied liquid is re-distilled through the pipe 16. Whereas the purer water vapour eventually enters the cooling tube 12, said cooling tube 12 is in the form of a spiral, and said cooling tube 12 is placed in the heat exchange tube 11. The heat exchange tube 11 is provided with a cooling liquid inlet and a cooling liquid outlet, wherein the cooling liquid inlet is arranged at the bottom of the heat exchange tube 11, and the cooling liquid outlet is arranged at the bottom of the heat exchange tube 11, and the cooling liquid inlet is arranged at the bottom of the heat exchange tube 11. The heat exchange tube 11 and the cooling tube 12 form a heat exchanger, and water vapor in the cooling tube 12 is liquefied into liquid through heat exchange to form purer clean liquid.
The repeated distillation through the distillation drum 1 and the sieving by the sieving drum 6 can ensure the distillation effect.
The foregoing description of the preferred embodiments of the invention is not intended to limit the invention to the precise form disclosed, and any such modifications, equivalents, and alternatives falling within the spirit and scope of the invention are intended to be included within the scope of the invention.
