Technical Field

[0001] The utility model relates to the technical field of high-salt wastewater treatment, in particular to a preheating device used for high-salt wastewater treatment. Background Art

[0002] High-salt wastewater refers to wastewater with a total salt content of at least 1%, which mainly comes from chemical plants and the collection and processing of oil and natural gas. This wastewater contains a variety of substances (including salt, oil, organic heavy metals and radioactive substances). The production of saline wastewater is extensive, and the amount of water is increasing year by year. It is very important to remove the impact of organic pollutants in saline wastewater on the environment. Chinese patent CN210340594U discloses a high-salt wastewater treatment device, which particularly relates to the technical field of wastewater treatment equipment. The utility model includes a support platform, a first support leg, a filter box, a preheating box, and an evaporation box.

One side of the filtrate storage area is connected to one end of a wastewater pump through a pipeline. A preheating pipe is provided in the preheating box. The other end of the wastewater pump is connected to one end of the preheating pipe through a pipeline. The other end of the preheating pipe is connected to one side of the evaporation box through a pipeline. One side of the preheating box is connected to one end of a suction fan through a pipeline, and one end of the suction fan is connected to the evaporation box through a pipeline. By preheating the wastewater with the water vapor generated during the evaporation process, the temperature of the high-salt wastewater before evaporation is increased, the evaporation rate of the high-salt wastewater is accelerated, energy is saved, and the wastewater treatment efficiency is improved.

[0018] The utility model will be further described below in conjunction with the accompanying drawings.

[0019] Please refer to Figure 1-Figure 3 The utility model discloses a preheating device for treating high-salt wastewater, comprising: a preheating tube 1, sealing seats 2 are arranged inside both ends of the preheating tube 1, the sealing seats 2 are connected to heating tubes 3, a plurality of heating tubes 3 are arranged, a plurality of heating tubes 3 are slidably connected to a piston plate 4, a first limiting ring 101 is arranged inside one end of the preheating tube 1, and a second limiting ring 102 is arranged inside the other end of the preheating tube 1.

[0020] Combination Figure 2 and Figure 3 As shown, the piston plate 4 is provided with a sliding hole 401 corresponding to the heating tube 3, and the piston plate 4 is slidably connected to the outer wall of the heating tube 3 through the sliding hole 401, so that the piston plate 4 can scrape off the stains on the surface of the heating tube 3, the piston plate 4 is circular, and a rubber ring 402 is provided on the outer side of the circumference of the piston plate 4, and the rubber ring 402 fits the inner wall of the preheating tube 1, and the bottom end of the preheating tube 1 is located on the side of the first limiting ring 101 and is provided with a first water inlet pipe 5, and the bottom end of the preheating tube 1 is located on the side of the second limiting ring 102 and is provided with a second water inlet pipe 6, and the lower ends of the first water inlet pipe 5 and the second water inlet pipe 6 are both provided with a first valve switch 7.

[0021] Among them, a first connecting pipe 8 is connected between the first water inlet pipe 5 and the second water inlet pipe 6, and a water inlet main pipe 9 is connected to the middle of the bottom end of the first connecting pipe 8. The first connecting pipe 8 is located on both sides of the water inlet main pipe 9 and is provided with a second valve switch 10. The top of the preheating pipe 1 is located on the side of the first limiting ring 101 and is provided with a first water outlet pipe 11. The top of the preheating pipe 1 is located on the side of the second limiting ring 102 and is provided with a second water outlet pipe 12.
