Description

Technical Field

[0001] The utility model relates to the technical field of organic waste liquid recovery, in particular to an organic waste liquid distillation recovery and treatment device. Background Technique

[0002] Organic waste liquid refers to waste liquid containing organic substances, mainly including organic solvents, organic acids, ethers, polychlorinated biphenyls, phenols, petroleum, oils and fats, etc. In the process of recovery, distillation equipment is needed to make the recovered substances form high-temperature steam, and then collect them by condensation.

[0003] After retrieval, the publication number is CN212594689U, and the name is a fine distillation residue tail gas recovery and treatment device, including a shell. Both ends of the shell are fixedly connected with a base. Through research and analysis, it is found that although the utility model has the characteristics of enhancing the treatment effect of tail gas, to a certain extent, there are still the following defects.

[0004] For example: the above-mentioned distillation recovery device cannot pre-cool the high-temperature steam. During the condensation process, due to the high temperature of the steam and the relatively fast passing speed of the high-temperature steam through the condensation equipment, incomplete condensation occurs and is discharged, resulting in an unsatisfactory recovery effect. Moreover, the waste liquid cannot be stirred during the distillation process, which will affect the heating speed of the waste liquid and reduce the distillation efficiency. To solve the above technical problems, we have designed an organic waste liquid distillation recovery and treatment device. Content of the Utility Model

[0005] The purpose of the utility model is to provide an organic waste liquid distillation recovery and treatment device, which has the advantages of a pre-cooling function, better waste liquid recovery effect, improved recovery quality, and stirring of the waste liquid to improve the heating and distillation efficiency, and solves the problems of inability to cool the steam, resulting in incomplete condensation, affecting the recovery effect, and reducing the waste liquid distillation efficiency.

[0006] To achieve the above purpose, the utility model provides the following technical solution: an organic waste liquid distillation recovery and treatment device, including a base plate. A distillation tank is fixedly connected to the left side of the top of the base plate. A driving motor is connected to the top of the distillation tank through bolts. The output shaft of the driving motor penetrates into the inner cavity of the distillation tank and is fixedly sleeved with a stirring rod. The right side of the top of the distillation tank is fixedly communicated with a first connecting pipe. The right side of the first connecting pipe penetrates and is fixedly sleeved with a cooling box. The right side of the cooling box is fixedly connected with a second connecting pipe. A heat exchange pipe is connected between the first connecting pipe and the second connecting pipe. The bottom of the second connecting pipe penetrates and is fixedly connected with a condensation tank. A condensation pipe is fixedly communicated with the bottom of the surface of the second connecting pipe. The bottom of the condensation pipe penetrates the condensation tank and is fixedly communicated with a liquid collection box. An air outlet pipe is communicated with the bottom left side of the condensation tank.

[0007] Preferably, the distillation tank comprises a tank body, a heating device is fixedly connected to the bottom of the inner cavity of the tank body, heating plates are fixedly connected to both the left and right sides of the top of the heating device, a partition plate is fixedly connected to the inner cavity of the tank body, and the top of the heating plate penetrates through to the top of the partition plate.

[0008] Preferably, a liquid inlet valve and a liquid discharge valve are respectively communicated with the top and bottom of the left side of the distillation tank, and an exhaust duct is communicated with the top of the cooling box.

[0009] Preferably, one side of the air outlet duct away from the condensation tank is communicated with the bottom of the cooling box, and an annular air duct is fixedly communicated with the top of the condensation tank.

[0010] Preferably, a liquid outlet valve is communicated with the bottom of the right side of the liquid collection box, and double-brake walking wheels are connected to the four corners of the bottom of the base plate through bolts.

[0011] Preferably, an exhaust housing is fixedly communicated with the right side of the rear side of the top of the liquid collection box, and an activated carbon purification filter screen is filled in the inner cavity of the exhaust housing.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] The low-temperature cold air contacts the high-temperature steam in the condensation pipe, condenses to form a liquid and flows into the liquid collection box, and the air that is heated after contacting the condensation pipe flows into the cooling box through the air outlet duct to exchange heat with the steam in the heat exchange pipe. In this way, the high-temperature steam can be pre-cooled, and it is more beneficial to condense it subsequently after reducing the temperature of the steam in the heat exchange pipe, thereby improving the condensation efficiency.

[0014] The heating device heats and distills the waste liquid through the heating plates, and the driving motor drives the stirring rod to rotate to stir the waste liquid. In this way, heating and stirring simultaneously can make the waste liquid receive heat more evenly, improve the heating speed of the waste liquid, and have a higher distillation efficiency.

[0023] Please refer to Figure 2 , one side of the air outlet duct 18 away from the condensation tank 15 is communicated with the bottom of the cooling box 9, the top of the condensation tank 15 is fixedly communicated with an annular air duct 12, and by setting the annular air duct 12, cold air can be evenly blown to the condensation pipe 19;

[0024] Please refer to Figure 1, a liquid outlet valve 14 is connected to the bottom on the right side of the liquid collecting tank 2. By setting the liquid outlet valve 14, the liquid recovered in the liquid collecting tank 2 can be conveniently pumped out. Double-brake walking wheels 3 are connected to the four corners of the bottom of the base plate 1 through bolts. By setting the double-brake walking wheels 3, the device can be conveniently moved to a suitable operating position;

[0025] Please refer to Figure 3 , an exhaust housing 13 is fixedly connected to the right side at the rear of the top of the liquid collecting tank 2.
