Description

Technical Field

[0001] The invention belongs to the field of pyrolysis treatment of oily sludge, in particular to a pyrolysis treatment device for oily sludge. Background Art

[0002] Oily sludge refers to sludge mixed with heavy oils such as crude oil, various refined oils, and residual oil. Oily sludge does not exist naturally; rather, it forms due to various industrial, civilian, and personal factors related to crude oil and refined oil, including oilfield extraction, refining, transportation, use, and storage. This sludge is caused by accidents, improper operation, outdated, damaged, and corroded equipment, which causes crude oil and refined oil to escape, leak, and then to the ground, settle on the bottom of oceans, lakes, and rivers, and mix with soil and water to form a mixture of oil, soil, water, and even other pollutants. Oily sludge is harmful to humans, plants, and aquatic life. The evaporated oil vapor in the air can irritate the skin, eyes, and respiratory organs, rendering the land incapable of plant growth. It is difficult to treat and remediate, making it a major pollutant in the petroleum and petrochemical industries.

[0003] The existing oily sludge pyrolysis treatment device has the following disadvantages:

[0004] 1. Uneven heating causes only the surface of the oily sludge close to the heat source to be evaporated and pyrolyzed, while the interior is not evaporated, resulting in insufficient decomposition.

[0005] 2. The degree of automation is low. Since oily sludge is a toxic substance, it needs to be sealed when handling it. Therefore, the door needs to be opened and closed frequently for loading and unloading, which is time-consuming and labor-intensive. Summary of the Invention

[0006] In order to make up for the shortcomings of the existing technology and solve the problem of uneven heating, which results in only the surface of the oily sludge close to the heat source being evaporated and pyrolyzed, while the interior is not evaporated, resulting in insufficient decomposition and low degree of automation. Since oily sludge is a toxic substance, the treatment of oily sludge requires sealing of the oily sludge, so loading and unloading requires frequent opening and closing of the door, which is time-consuming and labor-intensive.

[0007] The technical solution adopted by the present invention to solve the technical problem is: to provide an oily sludge pyrolysis treatment device, including: a conveying device, an evaporating device and a separating device;

With the arrangement of the impeller 3007, the rotation of the impeller 3007 will create a negative pressure inside the first fixing platform 3005, so that the steam inside the evaporation barrel 2001 is sucked into the first fixing platform 3005. The output shaft of the third driving motor 3010 penetrates through the second fixing platform 3009 and the inner wall of the first fixing platform 3005 and is in transmission connection with the impeller 3007, so that the rotation of the third driving motor 3010 can drive the impeller 3007 to rotate.

[0051] The specific working process is as follows:

[0052] Load the oily sludge into the feeding hopper 1001, and then start the first driving motor 1004. The first driving motor 1004 drives the spiral shaft 1006 to rotate. The rotation of the spiral shaft 1006 drives the oily sludge to move, and then it falls from the discharge port 1005 onto the top guiding platform 2003. Then start the electric telescopic rod 2013 under the top guiding platform 2003. The push rod of the electric telescopic rod 2013 extends to drive the second connecting rod 2012 to swing. The swing of the second connecting rod 2012 drives the first connecting rod 2010 to swing. Since the double-door 2009 is slidably connected to the chute on the first connecting rod 2010 through the first fixing pin 2011, one of the door panels of the double-door 2009 is driven to move outwards. The first connecting rod 2010 will drive one of the gears 2014 to rotate, and one of the gears 2014 will drive the other gear 2014 to rotate in the opposite direction, so that the other gear 2014 drives the other first connecting rod 2010 to swing in the opposite direction, so that the other door panel moves outwards, so that the two door panels of the double-door 2009 move away from each other, realizing the opening of the double-door 2009, and making the material slide into the evaporation barrel 2001 along the guidance of the guiding platform 2003. Start the electric telescopic rod 2013 to make the push rod of the electric telescopic rod 2013 contract. The two door panels of the double-door 2009 will approach each other, thus sealing the oily sludge. Then start the microwave generator 2008 to heat the oily sludge. Then start the second driving motor 2005. The rotation of the second driving motor 2005 will drive the third connecting rod 2017 to rotate. The rotation of the third connecting rod 2017 will drive the connecting frame 2006 to swing through the second ball hinge 2007. The swing of the connecting frame 2006 drives the evaporation barrel 2001 to swing, so as to turn the oily sludge inside by the swing of the evaporation barrel 2001, making the inside and outside of the oily sludge evenly heated. The oily sludge will be decomposed into steam after heating. Then start the third driving motor 3010. The third driving motor 3010 drives the impeller 3007 to rotate. The rotation of the impeller 3007 will form a negative pressure in the first fixing platform 3005, and then suck the steam inside the evaporation barrel 2001 into the first fixing platform 3005, and then enter the water pipe 3004 from the ventilation grille 3008 on the first fixing platform 3005. The steam will enter the inside of the oil-water separator 3001 along with the water pipe 3004. Then start the oil-water separator 3001 to decompose the steam into oil and water, and then transport them to the oil tank 3002 and the water tank 3003 respectively. When the evaporation is completed, start the electric telescopic rod 2013 of the bottom guiding platform 2003 to open the double-door 2009 of the bottom guiding platform 2003, and then transfer the decomposed oily sludge away.
