[0002] In the petrochemical industry, the steam cracking unit is one of the core equipment, and its stable operation is crucial to the efficiency of the entire production process and the quality of the product. During the steam cracking process, the raw materials are cracked under high temperature and high pressure to produce a variety of hydrocarbons and non-hydrocarbon compounds, which inevitably carry liquid impurities such as water and heavy hydrocarbons.

[0003] Steam filters are mainly installed at the inlet end of the pressure reducing valve, pressure relief valve, water level valve or other equipment of the steam cracking unit to remove impurities in the steam, such as moisture, oil droplets, solid particles, etc., to protect the normal use of downstream valves and equipment. Through filtering, the purity of the steam can be improved, and the operating efficiency and stability of the system can be improved.

[0004] Traditional deliquoring devices mostly adopt a fixed structure design, and the filtering devices inside them are often difficult to disassemble and install quickly. When the filtering elements need to be replaced or maintained due to blockage, damage, etc., it is usually necessary to shut down the machine, disassemble a large number of parts, and use professional tools for tedious operations, which not only increases the complexity and time cost of maintenance, but also may cause production interruptions and affect the overall economic benefits. Therefore, in view of the above problems, a deliquoring device for steam from a steam cracking unit is proposed. Summary of the invention

[0007] Preferably, one end of the clamping block away from the deliquidation device body is fixedly connected to a finger handle; the upper end of the finger handle is fixedly connected to a first closing block; the lower end of the finger handle is fixedly connected to a second closing block; the second closing block and the first closing block are both slidably connected to the clamping plate.

[0008] Preferably, the filter element device comprises a filter housing; the inner side of the connecting pipe is threadedly connected to the filter housing; and a plurality of groups of filter screens are fixedly connected to the inner side of the filter housing.

[0009] Preferably, one end of the connecting pipe away from the deliquidation device body is fixedly connected with a bellows; the bellows has a wavy shape.

[0010] Preferably, one end of the bellows away from the connecting pipe is fixedly connected to a connecting head; the inner side of the connecting head is rotatably connected to a rotating head.

[0011] Preferably, a plurality of groups of anti-sliding blocks are fixedly connected to the outer side of the rotating head.

DETAILED DESCRIPTION

[0023] 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 described embodiments 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 without creative work are within the scope of protection of the present invention.

[0024] like Figures 1 to 4 As shown, a deliquidation device for steam from a steam cracking device comprises a deliquidation device body 101; a clamping plate 103 is installed at the end of the deliquidation device body 101; a connecting pipe 102 is fixedly connected to the inner side of the clamping plate 103; a plurality of groups of clamping blocks 104 are slidably connected to the inner side of the clamping plate 103; the clamping block 104 is slidably connected to the deliquidation device body 101; a plurality of groups of limiting columns 105 are fixedly connected to the inner side of the clamping plate 103; the limiting columns 105 are slidably connected to the clamping block 104; a spring 106 is arranged between the clamping block 104 and the clamping plate 103 and on the outer side of the limiting column 105; the two ends of the spring 106 are fixedly connected to the clamping plate 103 and the clamping block 104 respectively; a filter element device is arranged on the inner side of the connecting pipe 102; during operation, when it is necessary to repair or replace the filter device, the clamping block 104 is pulled, The clamping block 104 is retracted to the inner side of the clamping plate 103, so that the clamping block 104 is separated from the dehydrating device body 101, and then the clamping plate 103 is pulled out from the inner side of the dehydrating device body 101. When the filtering device needs to be installed, the clamping block 104 is pulled to shrink the clamping block 104 to the inner side of the clamping plate 103, and then the clamping plate 103 is slid into the inner side of the dehydrating device body 101, and then the clamping block 104 is released. The elastic characteristics of the spring 106 allow the clamping block 104 to slide into the inner side of the dehydrating device body 101, so that the device can be quickly repaired or replaced. In this step, multiple groups of clamping blocks 104 slide on the inner side of the dehydrating device body 101, so that the filtering device can be quickly disassembled and installed, which significantly improves the convenience of maintenance and replacement, does not require complicated tools or long-term operation, effectively reduces maintenance costs, and improves work efficiency.

[0025] like Figures 1 to 4 As shown, the end of the clamping block 104 away from the dehydration device body 101 is fixedly connected with a finger handle 201; the upper end of the finger handle 201 is fixedly connected with a first closing block 202; the lower end of the finger handle 201 is fixedly connected with a second closing block 203; the second closing block 203 and the first closing block 202 are both slidably connected to the clamping plate 103; during operation, the clamping block 104 is moved by pulling the finger handle 201, and at the same time, the first closing block 202 and the second closing block 203 are moved when the finger handle 201 moves, so that the groove where the limiting column 105 is located is in a sealed state, thereby reducing the entry of impurities and dust into the groove. In this step, the finger handle 201 makes it more convenient for the staff to move the clamping block 104. At the same time, the first closing block 202 and the second closing block 203 are used to reduce the entry of impurities and dust into the groove, thereby maintaining the elastic characteristics of the spring 106 and increasing the service life of the device.

[0026] like Figures 2 to 3 As shown, the filter element device includes a filter housing 301; the inner side of the connecting pipe 102 is threadedly connected to the filter housing 301; the inner side of the filter housing 301 is fixedly connected to multiple groups of filter screens 302; when working, the filter housing 301 is rotated to separate the filter housing 301 from the connecting pipe 102, so as to replace the new filter housing 301 and the filter screen 302. In this step, by replacing the filter housing 301 and the filter screen 302, the replacement cost is reduced, and the user can only replace the worn or damaged parts instead of the entire device, thereby realizing the maximum utilization of resources and effective control of costs.

[0027] like Figure 1 to Figure 2 As shown, the end of the connecting tube 102 away from the deliquidation device body 101 is fixedly connected with a bellows 401; the bellows 401 has a wavy shape; during operation, when the staff needs to move the clamping plate 103, the structural characteristics of the bellows 401 allow the clamping plate 103 to have a larger space to move. In this step, by moving the clamping plate 103 with a larger space, more space is freed up for replacing the filter element device, making it more convenient to replace the filter element device.

[0028] like Figure 1 , Figure 2 and Figure 5 As shown, the end of the bellows 401 away from the connecting pipe 102 is fixedly connected with a connecting head 501; the inner side of the connecting head 501 is rotatably connected with a rotating head 502; when working, the rotating head 502 is rotated so that the rotating head 502 is threadedly connected to the steam pipe, so that the device can be quickly connected to the steam pipe.

[0029] like Figure 1 , Figure 2 and Figure 5 As shown, the outer side of the rotating head 502 is fixedly connected with multiple groups of anti-sliding blocks 601 ; during operation, the anti-sliding blocks 601 make it more convenient for the staff to rotate the rotating head 502 .

[0030] like Figure 3 As shown, during operation, after the filter housing 301 is threadedly connected to the connecting pipe 102, the gap between the filter housing 301 and the clamping plate 103 is sealed by the sealing gasket 701, thereby reducing resource waste.

[0031] Working principle: During operation, when the filter device needs to be repaired or replaced, the clamping block 104 is pulled to make the clamping block 104 shrink to the inner side of the clamping plate 103, so that the clamping block 104 is separated from the dehydration device body 101, and then the clamping plate 103 is pulled out from the inner side of the dehydration device body 101. When the filter device needs to be installed, the clamping block 104 is pulled to make the clamping block 104 shrink to the inner side of the clamping plate 103, and then the clamping plate 103 is slid into the inner side of the dehydration device body 101, and then the clamping block 104 is released, and the elastic characteristics of the spring 106 make the clamping block 104 slide into the dehydration device body 101. The inner side of the device can be quickly repaired or replaced; in this step, multiple sets of snap-fit ​​blocks 104 slide on the inner side of the deliquidation device body 101, so that the filter device can be quickly disassembled and installed, which significantly improves the convenience of repair and replacement, does not require complex tools or long-term operation, effectively reduces maintenance costs, and improves work efficiency. The snap-fit ​​block 104 is moved by pulling the finger handle 201. At the same time, the first closing block 202 and the second closing block 203 are moved when the finger handle 201 moves, so that the groove where the limit column 105 is located is in a sealed state, thereby reducing the entry of impurities and dust into the groove. In this step, the staff moves the snap-fit ​​block 104 through the finger handle 201. The filter housing 301 is rotated to separate the filter housing 301 from the connecting pipe 102, thereby replacing a new filter housing 301 and a filter screen 302. In this step, by replacing the filter housing 301 and the filter screen 302, the replacement cost is reduced. The user can only replace the worn or damaged parts instead of the entire device, thereby maximizing the utilization of resources and effectively controlling costs. When the staff needs to move the card plate 103, The structural features of the bellows 401 allow a larger space for the clamping plate 103 to move. In this step, the larger space for moving the clamping plate 103 frees up more space for replacing the filter element device, making it more convenient to replace the filter element device. The rotating head 502 is rotated to make the rotating head 502 threadedly connected to the steam pipe, so that the device can be quickly connected to the steam pipe. The anti-sliding block 601 makes it more convenient for the staff to rotate the rotating head 502. After the filter housing 301 is threadedly connected to the connecting pipe 102, the gap between the filter housing 301 and the clamping plate 103 is closed by the sealing gasket 701, thereby reducing resource waste.

Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, and these changes and improvements all fall within the scope of the present invention to be protected.
