Description

Technical Field

[0001] The invention relates to the technical field of pressure reactors, in particular to waste gas leakage detection equipment for pressure reactors used in chemical production. Background Art

[0002] Conventional pressure reactor detection devices on the market are difficult to accurately detect the leakage position of the reactor due to their structural limitations. Moreover, most reactors have cylindrical shells, and ordinary external tank detection devices are difficult to fit tightly on the shell surface, and the sealing is poor. In addition, due to the different inner diameters of the reactors and the different curvatures of different shells, it is necessary to equip a variety of external tank detection devices for detection, and the detection cost is relatively high. A pressure reactor leakage detector with application number CN2016106225169 includes a pressure pump and a detection head. The detection head consists of a connecting rod and a sealing cover. The elastic sealing port and supporting spring on the sealing cover can be arbitrarily deformed according to the shape of the reactor shell. The sealing port is tightly adsorbed on the outside of the reactor shell. Through the change of the vacuum degree inside the sealing cover, it is timely judged that the reactor shell at that position has a leak.

[0042] Embodiment 4: Based on Embodiment 3, refer to the attached Figure 1 , Attachment Figure 5 ;

[0043] A purification component 5 is arranged outside the half set 2, and the purification component 5 includes a liquid tank 51, and the liquid tank 51 is loaded with a purification liquid for purifying the leaked gas. The outer surface of the liquid tank 51 is fixedly connected to the outer surface of one side of the half set 2, and the interior of the liquid tank 51 is connected with an exhaust pipe 52. One end of the exhaust pipe 52 extends to the bottom of the interior of the liquid tank 51 and is below the liquid level of the purification liquid. One end of the exhaust pipe 52 is fixedly connected to the body of the liquid tank 51 and extends to the outside of the half set 2. The interior of the exhaust pipe 52 is connected with an intake pipe 53, and the intake pipe 53 is arranged in parallel on the exhaust pipe 52 to recover the gas leaked inside the detection partition. One end of the intake pipe 53 is connected to the interior of the half set 2, and the interior of the exhaust pipe 52 is provided with a fan 54, and the fan 54 is electrically connected to the external control circuit.

[0044] An exhaust pipe 55 is passed through the interior of the liquid tank 51, and a sealing plate 56 is movably connected to the interior of the liquid tank 51. The sealing plate 56 is made of a material that is resistant to pressure, wear and corrosion and has good sealing properties. The body of the sealing plate 56 is movably connected to the outer surface of the exhaust pipe 52. A spring rod 57 is fixedly connected to the outer surface of the sealing plate 56. The spring rod 57 is made of a material that is resistant to pressure, corrosion and fatigue, and one end of the spring rod 57 is fixedly connected to the interior of the liquid tank 51.

[0045] By setting up the purification component 5 and utilizing the combination of the fan 54, the exhaust pipe 52 and the suction pipe 53, the leaked gas can be sucked into the liquid tank 51 and reacted with the purification liquid to be purified and discharged, thereby avoiding the problem of external pollution caused by the leaked gas and personal injury.

[0046] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0047] When working; first, the ring plate 6 is fixedly installed inside the half sleeve 2 through the arc strip 9 and the bolt 10, and then the fixing ring 8 is sleeved on the specified position outside the kettle body 1 and fixed by interference fit connection, then the two half sleeves 2 are attached to each other and wrapped around the outside of the kettle body 1, and at the same time, through the connection between the clamping groove 7 and the fixing ring 8, the fixing ring 8 and the ring plate 6 partition the outside of the kettle body 1, and then after the two half sleeves 2 are completely attached, the existing clamp is used to tie and fix the two, and then the purified liquid is added to the inside of the liquid tank 51, and it is submerged in the exhaust pipe 52 at one end inside the liquid tank 51, and then when the kettle body 1 is working, or the inside is inflated through the feeding end for detection;

[0048] During detection, the output end of the telescopic rod 41 is extended, so that the fork frame 43 drives the pressure-sensitive plate 44 and the gas sensor 47 to approach the outer wall of the kettle body 1, and then the output end of the driving motor 424 drives the gear 423 to rotate. Through the engagement of the gear 423 and the gear ring 422, the gear ring 422 drives the pressure-sensitive plate 44 and the gas sensor 47 to rotate around the kettle body 1 through the telescopic rod 41 and the fork frame 43. During the movement, the pressure-sensitive plate 44 performs a comprehensive longitudinal detection on the outer side of the kettle body 1. When there is a leak in the corresponding partition of the kettle body 1, gas is ejected from the holes or cracks, and the air flow contacts the pressure-sensitive plate 44. The air pressure causes the current and resistance of the circuit of the pressure-sensitive plate 44 to change to generate a pressure-sensitive signal. Then the fork frame 43 drives the gas sensor 47 to continue to move and put it in the previous position of the pressure-sensitive plate 44. Then the linear motor 46 moves along the slide rail 45, so that the gas sensor 47 follows the movement to perform longitudinal fixed-point detection, thereby improving the detection efficiency. The efficiency of measurement is improved, and gas leakage is avoided. At the same time, the fixed ring 8 also monitors the outer side of the kettle body 1 to which it is fixed, and also realizes the sealing effect. If there is a gas leakage problem, it can be detected by the gas sensor 47 after disassembly. After gas leakage occurs inside the partition, the fan 54 works through the exhaust pipe 52 and the corresponding suction pipe 53 to draw the leaked gas into the liquid tank 51, and after being filtered and purified by the purified liquid, it is isolated in the liquid tank 51 by the sealing plate 56. The gas power is buffered and offset by the elastic force of the spring rod 57. As a result, the air pressure between the sealing plate 56 and the purified liquid increases, and the gas pushes the sealing plate 56 to rise and compress the output end of the spring rod 57. When the sealing plate 56 rises, it is separated from the shielding of one end of the exhaust pipe 55, and then the purified gas is discharged through the exhaust pipe 55. When the air pressure value decreases, the output end of the spring rod 57 rebounds, so that the sealing plate 56 is reset.

[0049] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
