DETAILED DESCRIPTION

[0049] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field based on this application are within the scope of protection of the present invention.

[0050] In coke dry quenching waste heat power generation systems, drain expansion tanks are typically installed to recover drain water generated by the steam pipes. These tanks expand the volume of condensed drain water in the steam pipes, reducing its pressure. A portion of the drain water is vaporized into steam, while the remaining portion is cooled and introduced into a drain tank. The drain water is then regularly fed into the water supply system. Existing drain expansion tanks in the related art have limited drain water processing capacity, and a single drain expansion tank cannot meet the requirement for fully recovering the drain water. Therefore, improving the drain water processing capacity of a single drain expansion tank is an urgent problem for those skilled in the art.

[0051] In order to solve the above technical problems, the embodiments of the present application propose a hydrophobic expansion tank and a dry quenching waste heat power generation system.

[0052] like Figure 1 As shown, Figure 1 This is a structural diagram of the hydrophobic expansion container 10 according to an embodiment of the present application. Figure 1As shown from the top view, the embodiment of the first aspect of the present application provides a hydrophobic expander 10, which comprises a hydrophobic expander body 100, a first hydrophobic pipe 200 and a second hydrophobic pipe 300. Specifically, the hydrophobic expander body 100 comprises a shell 110, which surrounds an inner cavity; the shell 110 has oppositely arranged first and second side walls 111 and 112; the first side wall 111 is provided with a first hydrophobic interface 1111 communicating with the inner cavity; the second side wall 112 is provided with a second hydrophobic interface 1121 communicating with the inner cavity; the first and second hydrophobic interfaces 1111 and 1121 are arranged in a staggered manner; the first hydrophobic pipe 200 has a first connecting port 201 and a plurality of first hydrophobic ports 221 arranged at intervals; the first connecting port 201 is connected to the first hydrophobic interface 1111; the second hydrophobic pipe 300 has a second connecting port 3011 and a plurality of second hydrophobic ports 321 arranged at intervals; the second connecting port 3011 is connected to the second hydrophobic interface 1121.

[0053] The hydrophobic expander 10 of the embodiment of the present application comprises a hydrophobic expander body 100, a first hydrophobic pipe 200 and a second hydrophobic pipe 300. The hydrophobic expander body 100 comprises a shell 110, which surrounds an inner cavity; the shell 110 has oppositely arranged first and second side walls 111 and 112; the first side wall 111 is provided with a first hydrophobic interface 1111 communicating with the inner cavity; the second side wall 112 is provided with a second hydrophobic interface 1121 communicating with the inner cavity; the first hydrophobic pipe 200 has a first connecting port 201 and a plurality of first hydrophobic ports 221 arranged at intervals; the first connecting port 201 is connected to the first hydrophobic interface 1111; the second hydrophobic pipe 300 has a second connecting port 3011 and a plurality of second hydrophobic ports 321 arranged at intervals; in this way, the first hydrophobic ports 221 of the first hydrophobic pipe 200 and the second hydrophobic ports 321 of the second hydrophobic pipe 300 can both be used to input hydrophobic water into the inner cavity of the hydrophobic expander body 100. The hydrophobic expander 10 of the embodiment of the present application is provided with two hydrophobic pipes, i.e., the first hydrophobic pipe 200 and the second hydrophobic pipe 300, and each of the hydrophobic pipes has a plurality of hydrophobic ports, which increases the number of hydrophobic ports of the hydrophobic expander 10, so that a single hydrophobic expander 10 can be connected to more steam pipes to handle more hydrophobic water, thereby improving the hydrophobic water handling capacity of a single hydrophobic expander 10. At the same time, the first and second hydrophobic interfaces 1111 and 1121 are arranged in a staggered manner, which can prevent the problem of hydrophobic water collision caused by the direct arrangement of the first and second hydrophobic interfaces 1111 and 1121, and can make the hydrophobic water enter the inner cavity more smoothly.

[0054] By properly setting the volume of the hydrophobic expansion tank 10 and the number of hydrophobic ports, a single hydrophobic expansion tank 10 in the embodiment of the present application can achieve the hydrophobic processing capacity of two hydrophobic expansion tanks in the related art, which helps to reduce the space occupied by the hydrophobic expansion tank 10 in the dry quenching waste heat power generation system. Optionally, the volume of the hydrophobic expansion tank 10 can be 1.5 cubic meters, and the number of hydrophobic ports can be Figure 1 In the embodiment shown, there are 24, wherein the number of the first drain ports 221 is 14 and the number of the second drain ports 321 is 10. The distance between the axial direction of the first drain pipe 200 and the axial direction of the second drain pipe 300 may be 100 mm.

[0055] Alternatively, as Figure 1 As shown, the hydrophobic expansion container body 100 can be fixed to the wall through the mounting bracket 500 to achieve the installation and fixation of the hydrophobic expansion container 10 .

[0056] In some embodiments of the present application, Figure 1 As shown, the first hydrophobic pipe 200 extends from the first sidewall 111 along a first direction away from the hydrophobic expansion container body 100. The second hydrophobic pipe 300 includes a curved section 301 and a straight section 302. The curved section 301 bends from the second sidewall 112 toward the first sidewall 111, with a first end having a second connection port 3011 and a second end connected to the first end of the straight section 302. The second end of the straight section 302 extends along the first direction away from the curved section 301. This arrangement places the straight sections 302 of the first and second hydrophobic pipes 200 and 300 parallel to each other, facilitating the layout of the hydrophobic expansion container 10. The first direction may be the extension direction of the hydrophobic expansion container body 100, with the first and second sidewalls 111 and 112 facing each other in the first direction. The hydrophobic expansion container body 100 may be cylindrical.

[0057] In some embodiments of the present application, Figure 1 and Figure 2 As shown, Figure 2 for Figure 1 In the A-direction view of the hydrophobic expansion container 10, when the hydrophobic expansion container 10 is in operation, the upper portion is referred to as the "top" and the lower portion is referred to as the "bottom". The descriptions of "top" and "bottom" hereinbelow correspond to this definition. The axes of the first hydrophobic pipe 200 and the second hydrophobic pipe 300 are located in the same plane, which helps to reduce the space occupied by the hydrophobic expansion container 10 in the vertical direction. A plurality of second hydrophobic ports 321 are formed on the straight section 302, making the entry of hydrophobic water smoother. The top wall 113 and the bottom wall 114 of the hydrophobic expansion container body 100 are arranged opposite to each other in the vertical direction.

[0058] In some embodiments of the present application, Figures 1 to 3 As shown, Figure 3 for Figure 1The local view of the B view of the figure shows that the first drain pipe 200 includes a first pipe 210 and a plurality of first short pipes 220 arranged at intervals on the first pipe 210, and the first short pipes 220 have first drain openings 221; the first short pipes 220 are arranged at an acute angle with the first pipe 210; the second drain pipe 300 includes a second pipe 310 and a plurality of second short pipes 320 arranged at intervals on the second pipe 310, and the second short pipes 320 have second drain openings 321; the second short pipes 320 are arranged at an acute angle with the second pipe 310. The first short pipes 220 and the second short pipes 320 are respectively connected with steam pipes, compared with the first drain openings 221 arranged on the first pipe 210, the second drain openings 321 arranged on the second pipe 310, the connection mode of the short pipes is more reliable, and the operation space is larger, which is convenient for connection; the arrangement mode of the acute angle, that is, the first short pipes 220 are arranged at an inclination relative to the first pipe 210, and the second short pipes 320 are arranged at an inclination relative to the second pipe 310, so that the flow of the drain is more smooth.

[0059] Optionally, the included angle θ between the first short pipe 220 and the first pipe 210 is 45°, and the included angle between the second short pipe 320 and the second pipe 310 is 45°. A plurality of first short pipes 220 can be uniformly arranged on the first pipe 210 in the first direction, and the distance between two adjacent first short pipes 220 can be 250 mm; the free end of the first short pipe 220 can be provided with a connecting flange 222, so that the connection is more reliable. The arrangement mode of the plurality of second short pipes 320 can be the same as that of the first short pipes 220, which will not be described here.

[0060] In some embodiments of the present application, as shown in Figure 1As shown, the plurality of first hydrophobic openings 221 are sequentially and spacedly arranged along the extension direction of the first hydrophobic pipe 200, and in the adjacent two first hydrophobic openings 221, the pressure of the hydrophobic water flowing into the first hydrophobic opening 221 away from the hydrophobic expander body 100 is greater than or equal to the pressure of the hydrophobic water flowing into the first hydrophobic opening 221 close to the hydrophobic expander body 100; the plurality of second hydrophobic openings 321 are sequentially and spacedly arranged along the extension direction of the second hydrophobic pipe 300, and in the adjacent two second hydrophobic openings 321, the pressure of the hydrophobic water flowing into the second hydrophobic opening 321 away from the hydrophobic expander body 100 is greater than or equal to the pressure of the hydrophobic water flowing into the second hydrophobic opening 321 close to the hydrophobic expander body 100. That is, in the pipe extension direction of the first hydrophobic pipe 200 and the second hydrophobic pipe 300, the first hydrophobic opening 221 and the second hydrophobic opening 321 close to the hydrophobic expander body 100 are low-pressure interfaces, and the first hydrophobic opening 221 and the second hydrophobic opening 321 away from the hydrophobic expander body 100 are high-pressure interfaces. If necessary, a medium-pressure interface can also be provided between the low-pressure interface and the high-pressure interface. In this way, the hydrophobic water in the steam pipe can enter the inner cavity more easily, and the existence of high-pressure hydrophobic water close to the hydrophobic expander body 100 will not affect the inflow of low-pressure hydrophobic water away from the hydrophobic expander body 100 into the inner cavity.

[0061] Optionally, the thickness of the connecting flange 222 corresponding to the low-pressure interface, the medium-pressure interface and the high-pressure interface can be increased sequentially, so as to bear greater pressure.

[0062] In some embodiments of the present application, as shown in Figure 1 and Figure 2 and Figure 4 as shown, Figure 4 is a connection relationship diagram of the spray pipe 400 and the shell 110 in the embodiments of the present application. The shell 110 has a cooling water inlet 1131, and an inspection hole 1132, a diffusion hole 1133 and a water outlet 1141 which communicate with the inner cavity. The inner cavity is provided with the spray pipe 400. The spray pipe 400 is arranged close to the top wall 113 of the shell 110 and has a plurality of spray openings 410. The cooling water inlet 1131 is arranged on the top wall 113 of the shell 110 and communicates with the spray pipe 400. The diffusion hole 1133 and the inspection hole 1132 are arranged on the top wall 113 of the shell 110. The water outlet 1141 is arranged on the bottom wall 114 of the shell 110. In the working process of the hydrophobic expander 10, cooling water can be introduced into the spray pipe 400 through the cooling water inlet 1131. The cooling water enters the inner cavity of the hydrophobic expander body 100 through the spray openings 410 and exchanges heat with the high-temperature hydrophobic water in the inner cavity, thereby cooling the high-temperature hydrophobic water. The cooled hydrophobic water is discharged to a hydrophobic collection device such as a hydrophobic tank through the water outlet 1141. The steam generated in the heat exchange process is discharged through the diffusion hole 1133. The inspection hole 1132 is used for repairing the hydrophobic expander 10 when it fails.

[0063] The hydrophobic expansion vessel 10 of the embodiment of the present application increases the hydrophobic port, improves the hydrophobic processing capacity of the single hydrophobic expansion vessel 10, so that the hydrophobic in each steam pipeline can be recycled, the number of hydrophobic expansion vessels 10 in the dry quenching waste heat power generation system can be reduced, thereby reducing equipment investment, saving cost, improving economic benefit, and the layout of the dry quenching waste heat power generation system is more reasonable.

[0064] As shown in Figure 5 and Figure 6 , the hydrophobic expansion vessel 10 of the embodiment of the present application is a hydrophobic expansion vessel for the dry quenching waste heat power generation system, and the hydrophobic expansion vessel 10 includes a first hydrophobic pipe 100, a second hydrophobic pipe 300, and a hydrophobic expansion cavity 1000.
