Detailed Description
The following describes the embodiments and operation of the present invention with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention can be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.
The terms of orientation such as up, down, left, right, front, and rear in the present specification are established based on the positional relationship shown in the drawings. The corresponding positional relationship may also vary depending on the drawings, and therefore, should not be construed as limiting the scope of protection. In addition, in the following description of the embodiments, "a plurality" or "a plurality" means two or more unless specifically limited otherwise.
As shown in FIG. 1, the solid support 6 includes a drip tray 5, a drip tray skirt 10, and legs 7. As shown in FIG. 4, the high-pressure reaction kettle capable of automatically separating oil from solid can be placed in an electric furnace 1 for heating and boosting pressure, and comprises a reaction kettle cavity 2, a flange end cover 3 and a bolt 4. The flange end cover 3 and the reaction kettle cavity 2 can be fastened and connected through bolts 4. The solid phase support 6 shown in fig. 4 is arranged at the bottom of the reaction kettle cavity of the high-pressure reaction kettle to form the high-pressure reaction kettle for automatic oil-solid separation.
The solid phase support 6 is arranged at the bottom of the reaction kettle cavity 2 in a supporting way through a supporting leg 7. An oil drip tray enclosure 10 is arranged around the oil drip tray 5, and the lower part of the oil drip tray enclosure 10 is fixedly connected with the oil drip tray 5. The drip tray enclosure 10 has a height h of 1-5cm and an internal diameter d 1.
As shown in figure 2, the drip oil pan 5 adopts a screen mesh structure, and screen holes 8 on the screen mesh form oil leakage holes. The mesh number of the screen is preferably 20-100 meshes. The oil drip tray 5 is provided with an oil guide groove 13 with an arc-shaped cross section. The oil guide groove 13 can be of a non-porous structure or a screen structure, and when the latter is selected, the mesh diameter of the oil guide groove 13 is preferably smaller than that of the oil drip tray 5, so that the amount of oil phase directly dripping from the oil guide groove can be controlled.
As shown in fig. 3, the oil drip tray enclosure 10 is provided with a plurality of oil drainage slits 9 uniformly distributed along the circumference, and two ends of the oil guide groove 13 can be communicated with the oil drainage slits 9, so that the oil guide groove 13 and the oil drainage slits 9 are generally arranged in a one-to-two manner (one oil guide groove corresponds to two oil drainage slits). The width w of the oil drainage slit is 1-3 mm. The width of the flow cross section of the oil guide groove 13 is the same as the width of the oil drainage slit. When the oil guide groove 13 is made of a non-porous plate structure, the oil phase collected by the oil guide groove 13 flows out of the oil drainage slit 9.
Further, the drip tray 5 is provided with a gathering spring 12 having a pitch S of 1 to 3mm and a spiral outer diameter d 2. And has (d1-d2) <1-10 mm.
When combustible solid waste high-pressure hydrolysis research is carried out, water is added into a reaction kettle, solid combustible solid waste 11 is loaded in a material gathering spring 12 of an oil drip tray 5 on a solid phase support, and the oil drip tray 5 is positioned above the water surface in the reaction kettle. When the reaction kettle is heated in an electric furnace, water at the bottom is vaporized and rises to the upper space of the solid phase support, and high-pressure hydrolysis reaction occurs. Combustible solid waste and water/vapor react to generate oil and solid phase products, then the oil drips along the sieve holes 8 or overflows to the lower part of the reaction kettle along the oil guide groove 13 from the oil drainage slit 9 to be mixed with water, and the reacted solid phase is still mostly loaded on the oil drip tray, so that the preliminary separation of the oil phase and the solid phase is realized under the action of gravity drainage and screen interception.
The oil guide groove 13 is a circular arc-shaped section, and liquid-phase products generated in the reaction can be collected in the oil guide groove, and flow to two ends to overflow out through the oil drainage slit 9 after being collected to a certain amount. The height of the gap of the oil drainage slit 9 can be the same as that of the oil drip tray surrounding baffle 10 to form a through gap, and can also be lower than that of the oil drainage tray surrounding baffle 10, so that the oil phase can be ensured to flow out smoothly.
Combustible solid waste is placed in the material gathering spring 12, the combustible solid waste is restrained in a specific space by the spring, and the movement of solid materials can be limited when hydrolysis reaction occurs, so that the solid materials are effectively prevented from directly overflowing from the oil drainage slit 9. Gather the material spring and be helical structure, the material is high temperature resistant stainless steel, and the stainless steel wire diameter that constitutes gathering the material spring is less than 3 mm. The spiral outer diameter of the material gathering spring is smaller than the inner diameter of the oil drip tray, so that a certain gap is formed between the placed combustible solid waste and the oil drip tray enclosure, and oil gathering is facilitated. According to the particle size of the combustible solid waste, the combustible solid waste can be filled to a height higher than that of the aggregate spring or lower than that of the aggregate spring.
One embodiment is as follows: when carrying out discarded tire hydrolysis experiment, the automatic oil drip dish of the high pressure batch autoclave of solid separation of oil that adopts encloses the internal diameter d1 that keeps off is 50mm, drip dish 5 chooses for use 50 mesh screen cloth, and the draining groove is 4, and the drip dish encloses the height that keeps off 10 and is 2cm, and the width of draining slit 9 is 1mm, gathers material spring 12's spiral external diameter d2 and is 45 mm. In actual use, the mesh number of the screen and the width of the oil drainage slit are selected according to the surface tension and viscosity of the oil phase, and the thicker the oil is, the smaller the corresponding mesh number is, and the wider the slit is.
When improving current reation kettle, only need as required and the corresponding solid phase support of the interior space size processing preparation of reation kettle cavity, place the solid phase support in current reation kettle cavity can.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art.
