Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of oily sludge demulsification devices, in particular to an oily sludge ultrasonic demulsification treatment device. Background Art
[0002] Oily sludge refers to sludge mixed with heavy oils such as crude oil, various refined oils, and residual oil. Oily sludge is not inherent in nature, but rather a mixture of soil, water, and other pollutants. Oily sludge is harmful to humans, plants, and aquatic life. The oil vapors that evaporate into the air can irritate the skin, eyes, and respiratory organs, rendering the soil incapable of plant growth and making it difficult to treat and remediate.
[0003] Oil and water in oily sludge are mixed in the form of an emulsion. In oily sludge treatment projects, a demulsification process is required. Demulsification refers to the complete destruction of the emulsion, turning it into two immiscible phases. Demulsification is essentially the process of eliminating the stabilization conditions of the emulsion, causing the dispersed droplets to aggregate and separate. The existing demulsification process generally adds a demulsifier and separates the oil and water through stirring to achieve the purpose of treatment. However, using only demulsifiers for demulsification is not only time-consuming, but also fails to fully achieve oil-water separation, hindering the subsequent separation of oil, water, and sludge. Therefore, it is necessary to develop an ultrasonic demulsification treatment device for oily sludge with high demulsification efficiency and good demulsification effect. Utility Model Content
[0004] In response to the above technical problems, the utility model provides an ultrasonic demulsification treatment device for oily sludge with high demulsification efficiency and good demulsification effect, so as to solve the problems that the existing oily sludge demulsification device takes a long time and cannot fully achieve oil-water separation.
[0005] In order to solve the above technical problems, the utility model describes an ultrasonic demulsification treatment device for oily sludge, comprising a demulsification treatment box, an outer shell of the demulsification treatment box is provided with a water storage and heating box, a feed port is provided at the top of the demulsification treatment box through the water storage and heating box, an ultrasonic generator is fixedly connected to the top of the water storage and heating box, an ultrasonic vibration rod is fixedly connected to the top of the inner side of the demulsification treatment box, the ultrasonic vibration rod is controlled by the ultrasonic generator, a discharge port is provided at the lower outer side of the demulsification treatment box through the water storage and heating box, a motor is provided at the bottom of the water storage and heating box, an output end of the motor is fixedly connected to a shaft rod, the shaft rod extends into the demulsification treatment box, a stirring rod is fixedly connected to the outside of the shaft rod, an electric heater is fixedly connected to the bottom of the water storage and heating box, and a controller is provided at the top of the water storage and heating box.
[0006] Furthermore, a pH measuring machine is fixedly connected to the top of the water storage and heating box, a rotating arm is fixedly connected to the top of the inner side of the demulsification treatment box, and a probe is provided at the other end of the rotating arm. The probe and the rotating arm are controlled by the pH measuring machine to facilitate the measurement of the pH value. The pH measuring machine is communicatively connected to the controller.
[0007] Furthermore, the acidic solution storage barrel and the alkaline solution storage barrel are provided with a first discharge hopper at the bottom of the acidic solution storage barrel and a second discharge hopper at the bottom of the alkaline solution storage barrel, a first solenoid valve is provided at the bottom of the first discharge hopper, and a second solenoid valve is provided at the bottom of the second discharge hopper to facilitate adjustment of the pH value.
[0008] Furthermore, the first discharge hopper and the second discharge hopper pass through the top of the demulsification treatment box and the water storage and heating box, so as to facilitate the acid and alkali solutions to enter the demulsification treatment box.
[0009] Furthermore, the first solenoid valve and the second solenoid valve are controlled by the controller, which facilitates control operation.
[0010] Compared with the prior art, the present invention has the following advantages:
[0011] 1.
