The crude benzene gas can enter the two condensation boxes 2, and the condensed crude benzene liquid and crude benzene gas will enter the storage tank 1.

[0024] Condensation tubes 205 for condensing crude benzene gas are fixedly installed inside the two condensation boxes 2. Condensate is injected into the interior of the condensation box 2, and then the crude benzene gas enters the condensation tubes 205, so that the crude benzene gas in the condensation tubes 205 can be condensed and cooled. The condensation tubes 205 are curved to extend the time that the crude benzene gas stays inside the condensation tubes 205. Two cleaning boxes 206 are fixedly installed inside the two condensation boxes 2. The two cleaning boxes 206 are respectively located on both sides of the condensation tubes 205, and the two cleaning boxes 206 are in a mirror image state.

[0025] The two cleaning boxes 206 have rotating shafts 2062 rotatably connected to the inside of the opposite sides, and the outer surfaces of the two rotating shafts 2062 are fixedly installed with brush plates 2061. When the rotating shafts 2062 rotate, the brush plates 2061 are driven to rotate. When the side of the brush plate 2061 with bristles rotates to the outside of the cleaning box 206, it can contact the outer surface of the condenser 205. When the side of the brush plate 2061 with bristles rotates to the inside of the cleaning box 206, the brush plate 2061 can be flipped over and stored.

[0026] The outer surfaces of the two rotating shafts 2062 are fixedly installed with first gears 2063. When the first gears 2063 rotate, the rotating shafts 2062 are driven to rotate. Micro motors 2064 are fixedly installed on one side of the first gears 2063 inside the two cleaning boxes 206, and second gears 2065 are fixedly installed on the output ends of the two micro motors 2064. The two second gears 2065 are respectively engaged with the two first gears 2063. When the micro motor 2064 drives the second gears 2065 to rotate, the second gears 2065 will drive the first gears 2063 to rotate, and then drive the rotating shafts 2062 and the brush plate 2061 to rotate.

[0029] A first electric push rod 202 is fixedly installed on one side of the outer top surface of the condensation box 2, and the output end of the first electric push rod 202 is fixedly connected to the inner top surface of the lifting frame 203. The first electric push rod 202 can push the lifting frame 203 to move up and down.

The coolant can enter the condensation box 2 through the liquid inlet pipe 207, and the used coolant will be discharged from the condensation box 2 through the liquid outlet pipe 208.

[0031] The outer top surfaces of the two condensation boxes 2 are fixedly installed with transmission pipes 4, and the two transmission pipes 4 are respectively fixedly connected to the two condensation pipes 205, and the two transmission pipes 4 are commonly fixedly installed with a diversion pipe 3 at one end away from the condensation box 2.

[0032] Both condensing pipes 205 are fixedly connected to the storage tank 1, and the condensed crude benzene gas and crude benzene liquid will enter the storage tank 1. A discharge pipe 5 is fixedly installed on the outer bottom surface of the storage tank 1, and the crude benzene gas can be discharged through the discharge pipe 5. An exhaust pipe 6 is fixedly installed on one side of the outer surface of the storage tank 1, and the crude benzene gas will be discharged through the exhaust pipe 6.

[0033] Injection boxes 201 are fixedly installed on both sides of the outer surface of the condensation box 2, and the injection boxes 201 are used to store cleaning liquid for cleaning. Piston rods 204 are fixedly installed on both sides of the inner top surface of the lifting frame 203, and the two piston rods 204 extend to the inside of the two injection boxes 201 respectively.

When the piston 2041 descends inside the injection box 201, the cleaning liquid in the injection box 201 can be injected into the condensation box 2, and the brush plate 2061 and the scraper 2068 are used to clean the inside of the condensation box 2. A liquid replenishing pipe 2043 is fixedly installed on one side of the outer surface of the injection box 201. The cleaning liquid can enter the injection box 201 through the liquid replenishing pipe 2043. When the cleaning liquid is transmitted to the injection box 201, it is necessary to wait until the height of the piston 2041 is higher than the height of the liquid replenishing pipe 2043 before the cleaning liquid can be transmitted.

[0035] The working principle of the utility model is as follows: crude benzene gas enters into the shunt pipe 3, and enters into two transmission pipes 4 through the shunt pipe 3, and then enters into two condensation pipes 205 through two transmission pipes 4, and the coolant in the condensation box 2 can condense and cool the crude benzene gas in the condensation pipe 205, and the condensed and cooled crude benzene gas and crude benzene liquid will enter into the storage tank 1. When the condensation box 2 is used for a long time, the micro motor 2064 drives the second gear 2065 to rotate, which will drive the first gear 2063 and the rotating shaft 2062 to rotate, and then drive the brush plate 2061 to flip, so that the bristles of the brush plate 2061 are aligned with the condensation pipes. 205, and the second electric push rod 2067 pushes the scraper 2068 to move so that the scraper 2068 contacts the inner wall of the condensation box 2, and then the cleaning liquid is transmitted to the injection box 201 through the liquid replenishing tube 2043. As the first electric push rod 202 pushes the lifting frame 203 to move up and down, it will drive the cleaning box 206 to move up and down, and the bristles of the brush plate 2061 will wipe the outer surface of the condensation tube 205, and the scraper 2068 can scrape off the stains attached to the inner wall of the condensation box 2. At the same time, the cleaning liquid in the injection box 201 can be injected into the condensation box 2, and the brush plate 2061 and the scraper 2068 are used to clean the inside of the condensation box 2.
