DETAILED DESCRIPTION

[0036] In order to make the objects, technical solutions and advantages of the present application clearer, the technical solutions in the present application will be described clearly and completely below in combination with the drawings in the present application. Obviously, the described embodiments are some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the present application.

[0037] As Figures 1 to 11 shown, the embodiment of the present application provides an elliptical rotary drum 30 heating gasification device, which comprises a furnace shell 20, a shell 10, an elliptical rotary drum 30 and a driving device 40. The heating gasification device is described below.

[0038] The furnace shell 20 is provided with a material feeding pipe 21, and the material can enter the inside of the furnace shell 20 from the material feeding pipe 21. The material can be waste thin-layer plastic. The outer shell 10 is covered on the furnace shell 20, and the over-air passage is formed between the outer shell 10 and the furnace shell 20. The hot flue gas is introduced into the over-air passage. The liquid heat carrier is introduced into the inside of the elliptical rotary cylinder 30. The liquid heat carrier is heated to heat the elliptical rotary cylinder 30. The temperature of the outer surface of the elliptical rotary cylinder 30 is increased. The elliptical rotary cylinder 30 is arranged below the material feeding pipe 21. When the material enters from the material feeding pipe 21 and falls to the outer surface of the elliptical rotary cylinder 30, the material is in contact with the high-temperature outer surface of the elliptical rotary cylinder 30. At this time, the material can be gasified. The elliptical rotary cylinder 30 is provided with two elliptical rotary cylinders 30 which abut against each other and can rotate in the same direction. The two elliptical rotary cylinders 30 are arranged to rotate by 90 degrees. The two elliptical rotary cylinders 30 can rotate to extrude and gasify the material. After being extruded, the material is attached to the outer surface of the elliptical rotary cylinder 30. At this time, the contact area of the material with the high-temperature outer surface of the elliptical rotary cylinder 30 is increased, and the material is more easily gasified, just like making pancakes and making pressed noodles in life. The driving device 40 is in transmission connection with the two elliptical rotary cylinders 30 and simultaneously drives the two elliptical rotary cylinders 30 to rotate in the same direction. Through continuous rotation, the material is extruded to increase the contact area of the material with the elliptical rotary cylinder 30, and the material is more easily gasified. The elliptical rotary cylinder rotates by 36 degrees. In this way, the material is transported to the discharge port through rotation. (It is a bit like double-helix conveying)

[0039] The heating and gasification device is provided with a three-layer structure. The inner and outer layers are heated. The first layer (inner layer) is the liquid heat carrier (the present use is heat-conducting molten salt) in the inside of the elliptical rotary cylinder 30. The second layer (middle layer, which is also the material cracking and gasification layer) is the outer surface of the elliptical rotary cylinder 30 after being heated by the liquid heat carrier. The third layer (outer layer) is the introduced high-temperature hot flue gas. The continuously introduced high-temperature hot gas can keep the temperature and flow rate between the outer shell 10 and the furnace shell 20. The material is heated and gasified by the inner and outer layer heating mode, so that the heat efficiency of the heating and gasification device is high, and the material can be completely gasified.

[0040] In actual production, the temperature of the introduced liquid heat carrier is 600-700 degrees Celsius, the temperature of the passing hot flue gas is 600-800 degrees Celsius, and the reaction temperature of the material in the furnace shell 20 is 400-500 degrees Celsius. It should be understood that the hot flue gas here refers to the flue gas with a temperature of 600-800 degrees Celsius. The liquid heat carrier here is heat-conducting molten salt.

[0041] Because the space gap of the material in the furnace is constantly changing in the rotating process of the elliptical rotating cylinder 30, the material is squeezed from loose to extrusion and then loose, and the loose material can be accumulated to form coking and carbon deposition on the surface of the elliptical rotating cylinder 30, which can be removed through extrusion between the two elliptical rotating cylinders 30. The movement between the two elliptical rotating cylinders 30 is the same movement, and the installation positions are rotated by 90 degrees relative to each other to ensure that the gap between the two elliptical surfaces is constant during rotation, and the contact point line is constantly changing, thereby being more scientific and effectively cleaning the surface, thereby achieving the self-cleaning effect.

[0042] A pyrolysis gas exhaust pipe 22 is further arranged at the top of the furnace shell 20, and the pyrolysis gas exhaust pipe 22 is used to exhaust the gas after the material is gasified. A slag discharge pipe 23 is further arranged at the bottom of the furnace shell 20, and the slag discharge pipe 23 is used to discharge the slag after the material is extruded and gasified.

[0043] The outer shell 10 is provided with a hot flue gas inlet pipe 11 and a hot flue gas outlet pipe 12. The hot flue gas inlet pipe 11 is above the hot flue gas outlet pipe 12. The hot flue gas inlet pipe 11 can be arranged directly above the hot flue gas outlet pipe 12 or can be arranged above the side of the hot flue gas outlet pipe 12. By arranging the hot flue gas inlet pipe 11 above the hot flue gas outlet pipe 12, when high-temperature gas is introduced, the high-temperature gas will fill the interlayer gas channel from top to bottom, so that the temperature flow of the furnace shell 20 remains uniform, thereby transferring heat to the middle layer through the furnace shell 20.

[0044] Specifically, the hot flue gas inlet pipe 11 is arranged at the end of the outer shell 10 and above the furnace shell 20, and the hot flue gas outlet pipe 12 is arranged on the side wall of the outer shell 10 and below the furnace shell 20. The hot flue gas inlet pipe 11 and the hot flue gas outlet pipe 12 are arranged at the two ends of the outer shell 10 and distributed vertically. In this way, when high-temperature gas is introduced from the hot flue gas inlet pipe 11, the gas can uniformly fill the outer periphery of the furnace shell 20, so that the temperature of the furnace shell 20 remains uniform.

[0045] In order to avoid the temperature of the furnace shell 20 being affected by gas leakage and to eliminate the safety hazards caused by the mixing of flue gas and pyrolysis gas, the outer shell 10 and the furnace shell 20 are sealingly connected. One end surface of the elliptical rotating cylinder 30 is communicated with a liquid-state heat carrier inlet and outlet pipe 50, and the other end of the elliptical rotating cylinder 30 is drivingly connected to a driving device 40. Since the elliptical rotating cylinder 30 is arranged inside the furnace shell 20, the liquid-state heat carrier inlet and outlet pipe 50 is also connected to the furnace shell 20 by a rotary seal. Specifically, the driving device 40 is an electric motor.

[0048] During installation, in order to enable more liquid heat carriers to enter the inside of the elliptical rotary cylinder 30 and then be discharged from the liquid heat carrier outlet pipe 52, the inlet of the liquid heat carrier inlet pipe 51 and the outlet of the liquid heat carrier outlet pipe 52 are respectively close to the two end faces of the elliptical rotary cylinder 30, since the liquid heat carrier outlet pipe 52 is connected with one end face of the elliptical rotary cylinder 30, the inlet of the liquid heat carrier inlet pipe 51 is close to the end of the elliptical rotary cylinder 30 away from the liquid heat carrier outlet pipe 52 in the inside of the elliptical rotary cylinder 30.

[0049] Further, the end of the furnace shell 20 is provided with a connecting pipe 24, the liquid heat carrier outlet pipe 52 is partially arranged in the connecting pipe 24, and the connecting pipe 24 is connected with the liquid heat carrier inlet and outlet pipe 50 through a seal 60. By connecting the liquid heat carrier inlet and outlet pipe 50 with the connecting pipe 24 through the seal 60, the leakage of cracking gas between the connecting pipe 24 and the liquid heat carrier inlet and outlet pipe 50 can be avoided.

[0050] The sealing device 60 comprises a main support 61, a secondary support 62 and a shaft sleeve 63, the shaft sleeve 63 is sleeved on the liquid heat carrier discharge pipe 52 and tightly adheres to the liquid heat carrier discharge pipe 52, the main support 61 is fixedly connected with the end cover plate of the furnace shell 20 through the pipe flange, the secondary support 62 is sleeved on the shaft sleeve 63 and fixedly connected with the main support 61, there are sealing rings, packing and rotating friction plates in the sealing device 60, when the elliptical rotating cylinder 30 rotates, the pyrolysis gas in the furnace shell 20 will not be discharged or leaked.

[0051] In order to conveniently transmit the force generated when the driving device 40 operates to the elliptical rotating cylinder 30 to drive the elliptical rotating cylinder 30 to rotate, a transmission structure 70 is arranged between the driving device 40 and the elliptical rotating cylinder 30, and the transmission mechanism can drive the two elliptical rotating cylinders 30 to synchronously rotate.
