[0040] The following detailed description and example embodiments of the present invention can be better understood with reference to the accompanying drawings, in which elements and features of the present invention are identified by reference numerals.
[0041] Example 1
[0042] The dry quenching tank of this embodiment is as follows Figure 7 As shown, it includes a keel bracket 2 and a lining structure 1 installed on the keel bracket 2, and a bottom gate is opened at the bottom of the coke tank.
[0043] The lining plate structure 1 is as follows Figure 1-4 As shown, it includes a lining plate body 11, and at least one lining plate body 12 is provided on the lining plate body 11;
[0044] And a clamping plate 13 fixed to the lining plate body 12 , wherein the clamping plate 13 is provided with at least one through hole, and a tightening component 14 capable of acting on the keel bracket 2 and the clamping plate 13 is passed through the through hole.
[0045] The tank body includes two inclined sections and a vertical section connecting the inclined sections, which are, from top to bottom, a first inclined section, a vertical section, and a second inclined section. Lining structures are provided on the first inclined section, the vertical section, and the second inclined section.
[0046] In Example 1, the liner plate body 12 is a support ear 12, which is a rectangular plate and is vertically arranged on the back of the liner plate body 11. The clamping plate 13 is vertically arranged on the keel bracket 2. Through holes are opened on the support ears 12 and the clamping plate 13 in parallel with the support ears 12. The anti-support screws can directly pass through the through holes on the support ears 12 and the clamping plate 13. When the liner plate body 11 needs to be fixed, the screws are tightened by bolts to fix the liner plate body 11 to the keel bracket 2 of the coke tank. A reinforcing rib plate 3 is provided on the back of the liner plate body 11.
[0047] Furthermore, in order to achieve the overlap of the lining structure 1 on the coke drum, the edge of the lining plate body 11 is provided with a burr structure, which is overlapped on the keel bracket 2 through the burr structure, wherein the back side of the lining plate body 11 is provided with outward grooves along the edge, and the grooves are overlapped on the keel bracket 2 of the coke drum.
[0048] The lining structure 1 is filled with insulation material. Aluminum silicate with a heat resistance exceeding 1100°C is used as the insulation material to improve the airtightness of the coke drum. To improve the heat resistance of the coke drum, the lining structure 1 uses an alloy with a heat resistance exceeding 1100°C. The melting point of the metal material is 1350-1450°C. To increase the melting point of the material, an alloy with a higher temperature is selected. Preferably, it is an Fe-based WNiMo alloy. This alloy has high rigidity, low plasticity, high thermal strength, and can withstand temperatures above 1100°C without deformation. High-temperature alloys can also be used. Existing pure austenitic stainless steel has good high-temperature performance but poor strength and wear resistance. Therefore, this application can use austenitic alloy heat-resistant steel Mn13 as the material for the lining structure 1. It has higher thermal conductivity and wear resistance, and good oxidation resistance. After cooling, no oxide scale will form on the surface, avoiding oxidation failure caused by repeated oxide scale formation on the surface of the lining structure 1 after repeated use.

The clamping plate 13 is vertically arranged on the keel bracket 2, parallel to the supporting ear 12, and a through hole corresponding to the supporting ear 12 is opened on the clamping plate 13. The fixing piece 15 is an anti-support screw, which can directly pass through the through holes on the supporting ear 12 and the clamping plate 13. When the lining plate body 11 needs to be fixed, the fixing piece 15 is tightened by bolts to fix the lining plate body 11 on the keel bracket 2 of the coke tank.
[0051] Example 3
[0052] The structure of embodiment 3 is basically the same as that of embodiment 1, except that the support ear 12 is a columnar structure, and the clamping plate 13 is fixed on the keel bracket 2. Figure 6 As shown, a through hole adapted to the support ear 12 is provided on the card plate 13, so that the card plate 13 is sleeved on the columnar structure, and the support ear 12 of the columnar structure passes through the through hole of the card plate 13 to achieve preliminary fixation of the lining plate body 11, and then further tightened with screws or screws.
[0053] Example 4
[0054] The structure of Example 4 is basically the same as that of Example 3, except that the support ear 12 is a columnar screw structure, the clamping plate 13 is fixed on the keel bracket 2, and a through hole adapted to the support ear 12 is provided on the clamping plate 13, so that the clamping plate 13 is mounted on the columnar structure.
