Description

Technical Field

[0001] The invention relates to the technical field of distillation towers, in particular to a distillation tower safety device with an early warning function. Background Art

[0002] Distillation towers are chemical equipment made of rare metal materials such as titanium and their alloys. They have the characteristics of high strength, high toughness, high temperature resistance, corrosion resistance, and light specific gravity. Therefore, they are widely used in chemical, petrochemical, metallurgical, light industry, textile, alkali, pharmaceutical, pesticide, electroplating, electronics and other fields. There are many types of tower equipment. The distillation tower is a tower-type gas-liquid contact device for distillation. There are two main types: plate tower and packed tower.

A positioning rod 2108 is fixedly connected to the surface of the sliding plate 2116. The number of the positioning rods 2108 is six, and one end of the positioning rod 2108 is fixedly connected to a strip Rod 2109, the number of bars 2109 is two, a telescopic rod 2110 is fixedly installed on the top of one of the bars 2109, the number of telescopic rods 2110 is several, a piston 2111 is fixedly installed on one end of the telescopic rod 2110, the surface of the piston 2111 contacts the inner wall of the arc plate 2106, a tension spring 2112 is fixedly installed on the top of the bar 2109, the number of the tension spring 2112 is several, the tension spring 2112 is sleeved on the surface of the telescopic rod 2110, one end of the tension spring 2112 is fixedly connected to the bottom of the piston 2111, a semicircular clamping block 2113 is fixedly installed on the top of the bar 2109, the number of the semicircular clamping blocks 2113 is two, the tops of the two semicircular clamping blocks 2113 are in contact with the inner wall of the piston 21 11, the inner walls of the two semicircular clamping blocks 2113 are each provided with an inclined groove 2114, the surfaces of the inclined grooves 2114 are each provided with an air hole groove 2115, and the number of the air hole grooves 2115 is several, a connecting rod 2117 is rotatably installed on the inner wall of the pressure relief pipe 2101, one end of the connecting rod 2117 penetrates the surface of the pressure relief pipe 2101, and a meniscus 2118 is rotatably sleeved on the surface of the connecting rod 2117, and the number of the meniscus 2118 is several, a shaking alarm 2119 is fixedly installed on the top of the tower body 1, and the output end of the shaking alarm 2119 is fixedly connected to one end of the connecting rod 2117, and one end of the pressure relief pipe 2101 is fixedly connected to a branch pipe 2120, and the number of the branch pipe 2120 is two.

[0039] The specific implementation of this embodiment is as follows: when the internal pressure of the distillation tower is too high during operation, the pressure can be discharged outward through the pressure relief pipe 2101, and the pressure is accumulated at the top of the distillation tower, and its force can push the piston 2111 upward. At this time, the piston 2111 is separated from the semicircular clamping block 2113, so that the two semicircular clamping blocks 2113 can be separated, and the piston 2111 is upward and its surface is separated from the inner wall of the arc plate 2106, leaving a certain space for initial pressure relief, and at the same time, the pressure and steam rush upward and their force will act on the chute 2 114, the gas and steam will force the semicircular clamp 2113 to push to both sides when it hits the air hole groove 2115. The greater the pressure, the faster the steam and gas impact will force the semicircular clamp 2113 to push to both sides, so as to perform a rapid pressure relief operation. The sliding plate 2116 slides on the inner wall of the tower body 1, and the airtight pad 2107 can ensure the sealing of the sliding plate 2116 during the sliding process. The greater the impact of the semicircular clamp 2113 pushing to both sides, the larger the opening of the arc plate 2106 will be, and the entire space in the pressure relief pipe 2101 will be. It is used to perform rapid pressure relief operation. At the same time, when the steam and gas are discharged during pressure relief, the meniscus 2118 on the surface of the connecting rod 2117 will be impacted to rotate, so that the connecting rod 2117 drives the shaking alarm 2119 to alarm, which is used to remind the staff to perform early warning operation. When the pressure is discharged, the pressure inside the distillation tower is reduced, and the tension spring 2112 can drive the piston 2111 to move downward. At the same time, the telescopic rod 2110 can ensure the stability of the piston 2111 when it moves up and down, and play a certain role in guiding. The spring 2105 is no longer under stress and can be reset by pushing the arc plate 2106 with the help of the sliding rod 2104. The bracket 2102 and the fixed tube 2103 can fix the position of the spring 2105 so that it will not shift when under stress, thereby increasing stability. The bar 2109 and the connecting rod 2117 further increase the connection between the sliding plate 2116 and the arc plate 2106, making it more stable and more stable when moving. The gas and steam discharged during pressure relief will be diverted through the branch pipe 2120. Example
