Description

Technical Field

[0001] The present invention relates to a corrosion-resistant and leak-proof gas drainer, and in particular to a corrosion-resistant and leak-proof gas drainer applied to the technical field related to gas drainers. Background Art

[0002] The leak-proof gas drainer is a device connected to the outlet pipe of the gas pipeline at a certain distance. The gas in the pipeline can be blast furnace gas, coke oven gas, converter gas, etc. There are a lot of condensed water and suspended solids in the gas medium. The leak-proof gas drainer is a device that uses the water seal height to seal the gas, collects and discharges the condensed water, and the solid particles are deposited on the bottom plate of the cylinder and cleaned regularly; reducing the corrosion of gas-using equipment and storage devices.

[0003] The main structure of the anti-leakage gas drainer is composed of a cylinder, a condensate inlet pipe, an exhaust vent pipe, a sewage cleaning hand hole, a liquid level gauge, an anti-leakage device, and heat insulation. The cylinder is a multi-compartment structure, and the compartments are filled with water to form a water seal with a certain water column height to prevent the breakdown of gas with a certain pressure. Once the breakdown occurs due to lack of water in the drainer (the sealing water column decreases) or the medium pressure in the pipeline suddenly increases, the gas can be sealed by the gas leakage prevention device, which can effectively prevent the leakage of gas and prevent the occurrence of gas leakage accidents. For example, the specification of Chinese patent CN101701666B discloses an anti-leakage gas drainer and the specification of Chinese patent CN107131427A discloses a gas drainer with anti-leakage function.

[0004] However, there are three problems with the above patents. First, the anti-leakage devices are all arranged outside the drainer, resulting in a large overall volume, which leads to a large space requirement for the equipment during installation; secondly, since the composition of the gas contains a certain amount of acidic components and acidic microparticles, it has a corrosive effect on the various components of the drainer; in particular, coke oven gas contains impurities such as tar, naphthalene, benzene, ammonia, hydrogen sulfide, etc., which are extremely corrosive to the drainer. Although stainless steel materials with strong corrosion resistance are used according to the type of gas, single key components still suffer from corrosion damage in a very short time and have to be stopped and replaced; finally, when the water seal height has not dropped significantly, when the gas pressure entering the drainer with the condensate is high, it is also easy to break down, and there is still a risk of gas leakage.

DETAILED DESCRIPTION

[0017] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0018] The first implementation method: Figure 1-3 The figure shows a corrosion-resistant and leak-proof gas drainer, comprising an outer cylinder 1 with a controller, a gas sound and light alarm installed on the top of the outer cylinder 1, an inlet tank 2, two pressurized tanks 3 and a drain tank 4 are arranged inside the outer cylinder 1, the inlet tank 2 and the drain tank 4 are fixedly passed through the upper end of the outer cylinder 1 and extend to the top of the outer cylinder 1, the bottoms of the inlet tank 2, the two pressurized tanks 3 and the drain tank 4 are commonly connected with a chassis 105, and connecting pipes 6 are fixedly connected between the inlet tank 2 and the adjacent pressurized tank 3, the two pressurized tanks 3, and the drain tank 4 and the adjacent pressurized tank 3, and multiple connecting pipes 6 are all located near the top of the outer cylinder 1. The chassis 105 is fixedly connected to the bottom of the outer cylinder 1, and the bottoms of the liquid inlet tank 2, the two pressurized tanks 3, and the liquid discharge tank 4, which are far away from each other, are fixedly connected with hand holes 101, and the tops of the four are fixedly connected with exhaust pipes 301. The upper ends of the four exhaust pipes 301 extend to the top of the outer cylinder 1 and are fixedly connected to the exhaust main pipe 103. The exhaust main pipe 103 is in a normally closed state and can be opened for exhaust at regular intervals. The mouth of the hand hole 101 is fixedly passed through the outer cylinder 1 and extends to the outside of the outer cylinder 1. A liquid level indicator 104 is also installed on the upper end of the outer cylinder 1, and the detection end of the liquid level indicator 104 extends into the liquid inlet tank 2; The gas sound and light alarm, the liquid level indicator 104 and the solenoid valve are all connected to the controller signal. When the liquid level indicator 104 detects abnormal liquid level, it can directly feedback to the controller, and then the controller can control the gas sound and light alarm to alarm, so that the workers can perform maintenance in time and reduce the safety hazard of gas leakage.

[0019] like Figure 4-6 The liquid inlet tank 2 includes a liquid inlet tank cylinder 21, an inner water conduit 22 fixedly connected to the inside of the liquid inlet tank cylinder 21, and a liquid conduit port 23 fixedly connected to the outer end of the liquid inlet tank cylinder 21. The liquid conduit port 23 is fixedly connected to the adjacent connecting pipe 6. The liquid conduit port 23 is close to the upper end of the liquid inlet tank cylinder 21. The pressurized tank 3 includes a pressurized tank cylinder 31 and a liquid conduit 32 fixedly connected to the liquid conduit 32 inside the pressurized tank cylinder 31. The upper end of the liquid conduit 32 is fixedly penetrated through the pressurized tank cylinder 31. The tank cylinder 31 extends to the outside of the pressurized tank cylinder 31, the first connecting pipe 6 is connected between the liquid guide port 23 and the adjacent pressurized tank cylinder 31, the second connecting pipe 6 is connected between the liquid guide pipe 32 and the pressurized tank cylinder 31 of another pressurized tank 3, the anti-leakage buoy 5 includes a liquid discharge tank cylinder 41, an anti-leakage cylinder 42 fixedly connected to the top of the liquid discharge tank cylinder 41, a connecting ring plate 44 with holes fixedly connected to the inner wall of the bottom of the anti-leakage cylinder 42, and a connecting ring plate fixedly connected to the connecting ring plate The reduced diameter pipe 43 at the lower end of 44, the anti-leakage buoy 5 is placed in the anti-leakage cylinder 42, the outer end of the liquid discharge tank cylinder 41 is opened with an inlet, and the third connecting pipe 6 is connected between the inlet and the mouth of the adjacent liquid guide pipe 32. The outer ends of the liquid inlet tank cylinder 21, the two pressurized tank cylinders 31 and the liquid discharge tank cylinder 41 are fixedly connected with a connecting plate 201, and the two adjacent connecting plates 201 are connected by bolts. The outer end of the liquid discharge tank cylinder 41 is fixedly connected with an overflow pipe 102, and the overflow pipe 102 It is fixed through the outer cylinder 1 and extends outside the outer cylinder 1, and a solenoid valve is installed on the overflow pipe 102. When the water seal height is not reduced below the warning line and a breakdown phenomenon occurs, the controller can close the overflow pipe 102 through the solenoid valve, thereby achieving a leakage prevention effect. The heights of the multiple connecting pipes 6 and the exhaust manifold 103 are kept consistent, so that the liquid levels used for water seals in the inlet tank 2, the booster tank 3 and the drain tank 4 can be kept consistent and are all at a high level, thereby effectively ensuring the water seal effect; like Figure 6-7The anti-leakage float 5 is made of a hollow, lightweight, corrosion-resistant material, such as PPH material, and when the bottom of the anti-leakage float 5 contacts the connection between the anti-leakage cylinder 42 and the reduced diameter pipe 43, from top to bottom, the first five-point point of the anti-leakage float 5 is not higher than the central axis of the connecting pipe 6, and the outer end of the anti-leakage float 5 is fixedly connected with two groups of triangular limit blocks 51 distributed in a ring array, and the vertices of the two groups of triangular limit blocks 51 are in contact with the inner wall of the reduced diameter pipe 43, so that multiple triangular limit blocks 51 can limit the anti-leakage float 5, so that it is always in a coaxial state with the anti-leakage cylinder 42 and is not easy to deviate, so that it can stably block the mouth of the reduced diameter pipe 43 when it moves downward, and the lower end of the anti-leakage float 5 is also fixedly connected with a sealing gasket 52, which is a fluororubber gasket with a skeleton. The diameter of the sealing gasket 52 is larger than the inner diameter of the connection between the anti-leakage cylinder 42 and the reduced diameter pipe 43, so that it can effectively block the connection between the two.

[0020] When in use, water is poured into the liquid inlet tank 2, the booster tank 3 and the liquid discharge tank 4 in advance until water overflows from the overflow pipe 102, so that a water seal is formed in the outer cylinder 1, and the condensate and impurities in the gas pipeline enter the inner water pipe 22 from the upper end of the liquid inlet tank 2, and pass through the inner water pipe 22 to reach the bottom of the liquid inlet tank cylinder 21, so that the liquid in the liquid inlet tank 2 increases, and then enters the booster tank cylinder 31 along the connecting pipe 6, and then along the liquid pipe 32 and another connecting pipe 6 to reach another booster tank 3, and then along the third connecting pipe 6 to enter the anti-leakage cylinder 42, as shown in FIG. Figure 8 At this time, the liquid level is relatively high, so that the anti-leakage float 5 floats up under the action of buoyancy and presses on the top of the anti-leakage cylinder 42. At this time, the connection between the anti-leakage cylinder 42 and the reducing pipe 43 is in an open state. The excess water enters the drainage tank cylinder 41 along the connection and is discharged from the overflow pipe 102. The gas contained in the condensate will be blocked by the water in the above-mentioned entire flow channel, which will produce great resistance to it, making it difficult for it to reach the overflow pipe 102, thereby achieving a water seal.

[0021] like Fig. 9 When the water seal height is lowered to a level that is not high enough to float the anti-leakage float 5, the anti-leakage float 5 falls back to just seal the connection between the anti-leakage cylinder 42 and the reduced diameter pipe 43. At this time, if the gas that enters the drainer along with the condensate reaches the anti-leakage cylinder 42, it will be difficult to continue to be discharged. Under the action of the gas pressure, the anti-leakage float 5 will be in closer contact with the connection between the anti-leakage cylinder 42 and the reduced diameter pipe 43, thereby achieving a better sealing effect and preventing gas leakage.

[0022] The liquid inlet tank cylinder 21 is a double-layer structure, and the inner layer of the liquid inlet tank cylinder 21, the inner water pipe 22, the pressurized tank cylinder 31, the liquid pipe 32, the liquid discharge tank cylinder 41, the anti-leakage cylinder 42 and the reduced diameter pipe 43 are all made of PPH pipe materials, and the outer layer of the liquid inlet tank cylinder 21 and the chassis 105 are all made of carbon steel materials. The PPH pipe has the physical properties of light weight and stability to water; good mechanical properties of resistance to tensile and bending fatigue; good heat resistance and chemical stability, so it is widely used in the metallurgical industry for pickling, wastewater treatment, oxidation tanks, pickling tanks, light chemical industry papermaking wastewater treatment, pharmaceutical chemical waste gas and wastewater treatment, various chemical wastewater treatment and purification, chemical reaction transportation of acid and alkali liquids, hypochlorous acid, saline-alkali chemical media, etc. The introduction of this material in the drainer can greatly improve the corrosion resistance of the part of the structure inside the drainer that is directly in contact with the sealing medium, extend the service life, and reduce the frequency of maintenance and replacement.

[0023] In summary, on the one hand, the anti-leakage float 5 is arranged inside the outer cylinder 1, thereby effectively reducing the volume of the entire drainer and reducing the space requirement during installation; on the other hand, the structures inside the drainer that are directly in contact with the sealing medium are made of PPH material, which replaces the stainless steel and other materials in the prior art, greatly improving the corrosion resistance and effectively reducing the frequency of replacement and maintenance of the drainer; in addition, in the setting of the microseismic detection unit, when the water seal height is at a high level, when gas leakage occurs, it can be detected in time, and then the drainer can be closed in time, thereby further reducing the occurrence of gas leakage.

[0024] The second implementation method: Based on the first embodiment, this embodiment adds a microseismic detection unit, and the rest of the parts are consistent with the first embodiment.

[0025] Fig.10As shown, a microseismic detection unit is fixedly connected to the middle of the reduced diameter tube 43, and the microseismic detection unit includes a lining plate 71 and a bottom plate 73 fixedly connected to the inner wall of the reduced diameter tube 43, and a back plate 72 fixedly connected between the lining plate 71 and the bottom plate 73, the bottom plate 73 is located below the lining plate 71, and a plurality of straight holes 702 distributed in a circular array are drilled on the lining plate 71, and a flared hole 701 is also drilled on the lining plate 71, and the flared hole 701 is located in the middle of the plurality of straight holes 702, and a gas sensing string is connected between the lower mouth of the flared hole 701 and the back plate 72, and the cross-section of the flared hole 701 is conical, and the large-diameter side of the flared hole 701 faces upward The maximum inner diameter of the expanded hole 701 is 5-10 times the inner diameter of the straight hole 702. A spherical groove 703 and a detection groove 704 are excavated inside the back plate 72. The detection groove 704 is located below the spherical groove 703, and the two are interconnected. A sealing plate 92 is fixedly connected to the upper mouth of the detection groove 704, and a laser rangefinder 91 is fixedly installed on the inner bottom of the detection groove 704. A follower tube 93 is fixedly connected to the upper part of the sealing plate 92. The follower tube 93 is fixedly connected to the bottom of the gas sensing string. The follower tube 93 is an elastic non-transparent structure, and the sealing plate 92 is a hard transparent structure. The follower tube 93 and the laser rangefinder 91 are coaxially arranged.

[0026] like Fig.12 The air sensing string includes an air guide tube 81 fixedly connected to the lower mouth of the expanded hole 701, a limiting ball 83 fixedly connected to the end of the air guide tube 81 away from the expanded hole 701, and a hollow floating ball 82 fixedly wrapped around the outer end of the air guide tube 81 close to the limiting ball 83. An open ball shell 802 is placed in the spherical groove 703. A lower vertical rod 801 is fixedly connected to the lower end of the open ball shell 802. The lower vertical rod 801 is fixedly connected to the follower tube 93. The limiting ball 83 is located in the open ball shell 802 and fits against the inner wall of the open ball shell 802.

[0027] When the water seal height is high, the anti-leakage buoy 5 is still in the floating state, and the upper opening of the reducing pipe 43 is not closed, when the gas breakdown phenomenon occurs, the gas reaches the lining plate 71 and partially moves downward along the straight hole 702 and passes through it, such as Fig.11 , and most of them will enter the gas sensing string along the larger flared hole 701. Driven by the gas pressure, Fig.13 , causing the gas sensing string to move downward, thereby bending the follower tube 93. At this time, the laser beam emitted by the follower tube 93 will be blocked by the bent follower tube 93, resulting in relatively small data. At this time, the signal can be fed back to the controller, and the controller can control the solenoid valve to close, thereby also achieving the prevention of gas breakdown and further reducing the possibility of gas leakage. Compared with the existing technology, the anti-leakage effect can be further improved on the basis of water seal.

[0028] like Fig.12When there is no gas breakdown, the limit ball 83 is always at the top under the buoyancy of the hollow float 82. At this time, the follower tube 93 is in a vertical state, so that the laser energy of the follower tube 93 can directly irradiate the lower vertical rod 801, making the data larger. like Figure 14-15 The cross-section of the open spherical shell 802 is a fan-shaped structure greater than 180°, and the edge of the mouth of the open spherical shell 802 conflicts with the step of the inner wall of the spherical groove 703, and the middle part of the open spherical shell 802 conflicts with the inner wall of the spherical groove 703, so that the open spherical shell 802 can only move up and down along the spherical groove 703 in the spherical groove 703, and cannot rotate radially, thereby effectively ensuring that the follower tube 93 can always be coaxial with the follower tube 93 when vertical, thereby effectively ensuring the accuracy of the data detected by the follower tube 93, and effectively improving the accuracy of the detection of gas breakdown phenomenon.

[0029] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
