[0034] The technical solution of the present invention is further described below in conjunction with the accompanying drawings and specific embodiments.

[0035] like Figure 1-Figure 4As shown, a phenol water concentration device proposed by the present invention comprises a phenol water treatment box 1, a repetitive circulation component 2 is installed on the top of the phenol water treatment box 1, a phenol water concentration component 3 is installed on the bottom of the phenol water treatment box 1, and a cleaning component 4 is installed between the repetitive circulation component 2 and the phenol water concentration component 3;

[0036] The phenol water treatment box 1 comprises a phenol water concentration rack 101, and a water vapor transmission rack 102 is fixedly installed on the top of the phenol water concentration rack 101;

[0037] A phenol water raw material circulation pipe 105 is fixedly installed in the middle of the phenol water concentration rack 101, a water flow pipe 104 is fixedly installed on the side wall of the water vapor transmission rack 102, and a water vapor transmission pipe 103 is fixedly installed on the top of the water vapor transmission rack 102. The equipment adopts evaporation method to concentrate phenol water, and phenol-containing wastewater enters the heating zone, that is, between the circulation pipe 301 and the external water vapor transmission cylinder 201, through the phenol water raw material circulation pipe 105. Since the control valve connected to the phenol water concentration rack 101 is in a closed state, the phenol-containing wastewater is located between the circulation pipe 301 and the external water vapor transmission cylinder 201 by pressure, and then heated by the heating chamber 404 as a heat source to increase the temperature of the wastewater to the boiling point. The water is converted into water vapor in the evaporation zone and escapes from the water flow pipe 104, while the phenolic substances remain in the concentrated liquid due to the high boiling point. The water vapor transmission pipe 103 contacts the condensation zone through the pipeline, and the water vapor is cooled into water in the condensation zone and discharged, thereby realizing the concentration of phenol water.

[0038] like Figure 2-Figure 5As shown, the repetitive circulation component 2 also includes two pressure blocks 202, one pressure block 202 is fixedly installed on the top of the external water vapor transmission cylinder 201, and the other pressure block 202 is slidably installed on the side wall of the external water vapor transmission cylinder 201, and a telescopic belt 206 is fixedly installed between the two pressure blocks 202, and a limiting slide 203 is fixedly installed on the outside of the external water vapor transmission cylinder 201, and a slide rail rod 210 is fixedly installed inside the limiting slide 203, and a hollow transmission block 207 is slidably installed on one side of the slide rail rod 210, and the other pressure block 202 is fixedly installed on the top of the hollow transmission block 207. The side wall of the steam transmission cylinder 201 is provided with two vertical threaded tracks 205, and the side wall of the external water vapor transmission cylinder 201 is provided with two horizontal threaded tracks 204 connected with the two vertical threaded tracks 205. The inner walls of the vertical threaded tracks 205 and the horizontal threaded tracks 204 are fixedly installed with guide blocks of different thicknesses. A first spring 209 is fixedly installed between the hollow transmission block 207 and the limiting slide 203. An arc-shaped protrusion 208 is slidably installed inside the hollow transmission block 207. The arc-shaped protrusion 208 is slidably installed inside the horizontal threaded tracks 204 and the vertical threaded tracks 205. The hollow transmission block 207 is provided with a plurality of arc-shaped protrusions 208, and the arc-shaped protrusions 208 are slidably installed inside the horizontal threaded tracks 204 and the vertical threaded tracks 205. A second auxiliary spring is fixedly installed between 07 and the arc-shaped protrusion 208. When the water vapor is in the condensation zone, the water vapor transmission pipe 103 contacts the condensation zone through the pipeline. A small amount of cold air may flow back to the pipe mouth of the water vapor transmission pipe 103, causing a temperature difference at the pipe mouth of the water vapor transmission pipe 103. The temperature difference causes the water vapor attached to the inner wall of the water vapor transmission frame 102 to form liquid. These liquids are easy to drip from the side wall to the pressure block 202. If too many water droplets accumulate, they are easy to be re-passed from the external water vapor transmission cylinder 201 into the center of the phenol water concentration frame 101, affecting the concentration of the phenol water. As the water droplets Accumulation, according to the weight of the water droplets, another pressure block 202 moves downward along the slide rail 210 and the limit slide 203 with the hollow transmission block 207, and there is a height difference between the two pressure blocks 202 through the telescopic belt 206, and the water droplets are discharged along the water pipe 104. At the same time, the arc-shaped protrusion 208 squeezes it along the transverse threaded track 204, and the external water vapor transmission cylinder 201 is guided by the track of the transverse threaded track 204 to rotate, and the water droplets above the external water vapor transmission cylinder 201 are thrown into the water pipe 104 by the centrifugal force, thereby reducing the accumulation of water droplets and avoiding affecting the concentration of phenol water;

[0039] When the arc-shaped protrusion 208 moves along the transverse threaded track 204 to the vertical threaded track 205, the first spring 209 pushes the hollow transmission block 207 back to its original position, and the arc-shaped protrusion 208 is guided from the guide block of the vertical threaded track 205 to the guide block of the transverse threaded track 204. In detail, the diameter of the guide block of the transverse threaded track 204 toward the center of the external water vapor transmission cylinder 201 is smaller than the diameter of the guide block of the vertical threaded track 205 toward the center of the external water vapor transmission cylinder 201, and there is a thickness difference between the two, that is, the arc-shaped protrusion 208 is in a compressed state when it is located in the vertical threaded track 205. When the arc-shaped protrusion 208 enters the track of the transverse threaded track 204 through the second auxiliary spring, the arc-shaped protrusion 208 can slide along the transverse threaded track 204 due to the height difference.

[0040] like Figure 4-Figure 6 As shown, the phenol water concentration component 3 includes a protective sleeve 308 fixedly installed inside the phenol water concentration frame 101, and a circulation pipe 301 is fixedly installed inside the protective sleeve 308. An impurity collecting plate 302 is rotatably installed between the inner wall of the phenol water concentration frame 101 and the outer wall of the circulation pipe 301. The upper surface of the impurity collecting plate 302 is inclined, which is convenient for transmitting the introduced phenol water raw material to the central pipeline of the circulation pipe 301. The interior of the phenol water concentration frame 101 is fixed by a positioning ring pipe 304. A plurality of collecting tubes 303 are installed, and a through hole matching the collecting tubes 303 is opened on the surface of the impurity collecting plate 302. The impurity collecting plate 302 is fixedly installed at the bottom of the arc-shaped clear flow plate 401. The inner wall of the phenol water concentration rack 101 and the outer wall of the flow tube 301 are fixedly installed with a plurality of airbag cushions 307. A cleaning clamping block 305 is fixedly installed on one side of the airbag cushion 307. An external brush ball 306 is rotatably installed on one side of the cleaning clamping block 305. When the arc-shaped clear flow plate 401 is When rotating, the impurity collecting plate 302 rotates synchronously with the arc-shaped cleaning plate 401. When the through hole of the impurity collecting plate 302 moves to the collecting tube 303, the impurities scraped off by the arc-shaped cleaning plate 401 enter the impurity collecting area below along the through hole and the collecting tube 303. The positioning ring tube 304 is located on the peripheral side of the collecting tube 303 and is in a filled state. When the through hole of the impurity collecting plate 302 is not connected to the collecting tube 303, the impurities will not fall into the impurity collecting area, and the two The cleaning snap-fit ​​blocks 305 are located on both sides of the arc-shaped clear flow plate 401. When the arc-shaped clear flow plate 401 slides between the two cleaning snap-fit ​​blocks 305, the bristles on the surface of the external brush ball 306 scrape off the impurities. When the accumulated impurities are located on the impurity collecting plate 302 and contact the cleaning snap-fit ​​blocks 305, there is a speed difference between the cleaning snap-fit ​​blocks 305 and the impurity collecting plate 302, so that the impurities can be pushed into the collection tube 303, thereby improving the collection effect of the impurities and avoiding interference with the impurities.

[0041] In this embodiment, Figure 6-Figure 8As shown, the cleaning component 4 includes an auxiliary hollow sleeve 403 fixedly installed at the bottom of the external water vapor transmission cylinder 201, a heating chamber 404 is fixedly installed in the center of the phenol water concentration frame 101, a heating component is arranged inside the heating chamber 404, a piston rod 402 is slidably installed inside the auxiliary hollow sleeve 403, an arc-shaped clearing plate 401 is fixedly installed at the bottom of the piston rod 402, a first auxiliary spring is fixedly installed between the piston rod 402 and the auxiliary hollow sleeve 403, and the arc-shaped clearing plate 401 is arranged in a fitting state with the heating chamber 404 under the normal state of the auxiliary spring, and when the external water vapor transmission cylinder 201 rotates, the external water vapor transmission cylinder 201 is moved by the piston The rod 402 drives the arc-shaped clear flow plate 401 to contact the inner wall of the heating chamber 404. Since the heating chamber 404 serves as a heating component, the center of the phenol water concentration rack 101 is continuously a heating environment, and impurities entrained by water vapor are easily accumulated on the inner wall of the phenol water concentration rack 101. The impurities are easily dried and adhered to the inner wall of the heating chamber 404 when in contact with the heating chamber 404.
