Description

Technical Field

[0001] This utility model relates to the field of distillation and purification, and in particular to a continuous distillation and purification device for high-temperature phenol mixed with vaporized phenol. Background Technology

[0002] In the field of coal chemical by-product purification, the azeotropic distillation of high-temperature phenol and gasified phenol requires strict control of the mixing ratio to optimize separation efficiency. Existing equipment uses a premixed feed tank, which requires pre-melting solid high-temperature phenol and manually mixing it with liquid gasified phenol, resulting in three defects: (1) the premixing process is time-consuming and energy-intensive; (2) the ratio adjustment lags behind changes in operating conditions; and (3) the difference in mixing uniformity between batches affects the mass transfer effect in the tower. This mode is difficult to adapt to the need for real-time dynamic parameter adjustment in continuous production. Utility Model Content

[0003] The purpose of this invention is to provide a continuous distillation and purification device for high-temperature phenol blending and vaporization, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: A continuous distillation purification device for high-temperature phenol blending and vaporized phenol includes a continuous distillation unit, a feed tank, a stirring motor, support arms, a high-temperature phenol tank, a vaporized phenol tank, a feed inlet, a discharge pipe, a butterfly valve, and a flow valve. The continuous distillation unit has the same structure and principle as existing continuous distillation units, and is connected to the feed tank at the bottom left side. A stirring motor is installed on the left side of the feed tank. Support arms are welded to both sides of the top of the feed tank. The high-temperature phenol tank and the vaporized phenol tank are welded to the top of the support arms on both sides, respectively. The top of the high-temperature phenol tank and the vaporized phenol tank are both provided with feed inlets. The bottom of the high-temperature phenol tank and the vaporized phenol tank are both provided with discharge pipes, which are connected to the top of the feed tank. A butterfly valve and a flow valve are sequentially installed on each discharge pipe.

[0005] Preferably, the continuous distillation purification device for high-temperature phenol blending and vaporized phenol further includes a butterfly valve stem and a control handle. The butterfly valves on the feed pipes at the bottom of the high-temperature phenol tank and the vaporized phenol tank are connected by a butterfly valve stem. A control handle is installed on the butterfly valve stem, and the control handle drives the butterfly valve stem to synchronously control the opening and closing of the two butterfly valves.

[0006] The beneficial effects of this utility model are: This utility model is reasonably designed. The flow ratio of high-temperature phenol and gasified phenol is controlled by the flow valve and fed directly into the feed tank. No premixing is required, which improves efficiency. Moreover, the ratio can be adjusted at any time. The adjusted raw materials are fully mixed by the stirring motor, which is beneficial for subsequent purification. Attached Figure Description

[0009] The present invention will be further described below with reference to the accompanying drawings and specific embodiments: like Figures 1-2 As shown, a continuous distillation purification device for high-temperature phenol blending and vaporized phenol includes a continuous distillation device 1, a feed tank 2, a stirring motor 3, a support arm 4, a high-temperature phenol tank 5, a vaporized phenol tank 6, a feed inlet 7, a discharge pipe 8, a butterfly valve 9, and a flow valve 10. The continuous distillation device 1 has the same structure and principle as an existing continuous distillation device 1, and is connected to the feed tank 2 at the bottom left side. The stirring motor 3 is installed on the left side of the feed tank 2. Support arms 4 are welded to the left and right sides of the top of the feed tank 2. The high-temperature phenol tank 5 and the vaporized phenol tank 6 are respectively welded to the top of the support arms 4 on both sides. The top of the high-temperature phenol tank 5 and the vaporized phenol tank 6 are both provided with feed inlets 7. The bottom of the high-temperature phenol tank 5 and the vaporized phenol tank 6 are both provided with discharge pipes 8, which are respectively connected to the top of the feed tank 2. The butterfly valve 9 and the flow valve 10 are sequentially installed on the discharge pipes 8. The continuous distillation and purification device for high-temperature phenol blending and vaporized phenol also includes a butterfly valve stem 11 and a control handle 12. The butterfly valves 9 on the feed pipes 8 at the bottom of the high-temperature phenol tank 5 and the vaporized phenol tank 6 are connected by the butterfly valve stem 11. The control handle 12 is installed on the butterfly valve stem 11, and the butterfly valve stem 11 is driven by the control handle 12 to synchronously control the opening and closing of the two butterfly valves 9.

[0010] The working principle of this utility model is as follows: The raw materials in the feed tank 2 are directly supplied through the top high-temperature phenol tank 5 and the vaporized phenol tank 6. Both the high-temperature phenol tank 5 and the vaporized phenol tank 6 are connected to the feed tank 2 through the bottom feed pipe 8. The feeding ratio of the high-temperature phenol tank 5 and the vaporized phenol tank 6 is controlled by the flow valve 10. The control handle 12 drives the butterfly valve stem 11 to synchronously control the opening and closing of the butterfly valves 9 on the two feed pipes 8, so that the high-temperature phenol tank 5 and the vaporized phenol tank 6 feed synchronously, so as to ensure that the ratio of high-temperature phenol and vaporized phenol is the same as the ratio set by the flow valve 10. The raw materials entering the feed tank 2 are stirred evenly by the stirring motor 3 and injected into the continuous distillation unit 1 for purification.

[0011] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary in all respects, and thus equivalent variations within the scope of this invention are included within its scope.
