Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a wastewater treatment drying device. Background Technology

[0002] Wastewater treatment by evaporation and concentration is a process that removes water from wastewater, thereby achieving zero wastewater discharge or resource recovery. This method is widely used in industrial wastewater treatment, desulfurization wastewater treatment from coal-fired power plants, and high-salinity wastewater treatment.

[0003] The core of wastewater treatment by evaporation is to use thermal energy (such as waste heat from flue gas, steam, or other heat sources) to evaporate the water in the wastewater, ultimately forming solid crystals or concentrated liquid.

[0004] In existing wastewater treatment drying equipment, heating rods are used to heat the wastewater inside the tank. During the heating process, a scraper is driven to rotate, achieving the purpose of stirring and cleaning the surface of the heating rod. However, in practical applications, it has been found that after long-term use, the scraper surface wears down, creating gaps between it and the heating rod, resulting in the formation of a layer of scale on the heating rod surface. Over time, this scale layer firmly adheres to the heating rod surface, not only affecting the heating effect but also increasing the difficulty of subsequent cleaning. Therefore, a wastewater treatment drying equipment is proposed. Utility Model Content

[0032] Working principle:

[0033] Heating and drying: After the wastewater is added, the feed pipe 2 is in a closed state (a valve can be installed at the feed pipe 2 to control the opening and closing of the feed pipe 2). The exhaust pipe 10 is connected to the external steam treatment equipment. The motor 8 and the mosquito coil-type electric heating tube 20 are both started and running. The mosquito coil-type electric heating tube 20 heats the heat conduction plate 19, thereby heating the wastewater. The motor 8 drives the main shaft 14 to rotate.

[0034] After the drying process is completed: the mosquito coil-type electric heating tube 20 stops heating, the first electric push rod 4 drives the slide 3 to rise, the slide 3 drives the electric shaft to rise, the electric shaft drives the closing plug 13 to rise, and the waste discharge pipe 12 is fully opened. Then the first electric push rod 4 stops running, and the scraper 18 is still in contact with the top of the heat conduction plate 19 under the action of the spring 17. When the scraper 18 rotates, it can scrape the impurities to the waste discharge pipe 12 and let them be discharged.

[0035] Cleaning: With all components in their original positions, add water and cleaning agent into tank 1 through feed pipe 2. Open electric slide valve 9, and the second electric push rod 7 controls the ultrasonic vibrator 11 to be inserted into the water. Then, the ultrasonic vibrator 11 runs to clean the inside of tank 1. After cleaning, repeat the above operation of opening waste drain pipe 12 to drain the wastewater. A second cleaning can be performed, and all components can be reset (depending on actual needs).

[0036] It should be noted that, in actual use, an existing technology controller can be added. The controller is electrically connected to the first electric push rod 4, the second electric push rod 7, the motor 8, the electric slide valve 9, the ultrasonic host, and the mosquito coil-type electric heating tube 20 to facilitate overall control.
