[0001] The present invention relates to the field of emergency treatment equipment for hazardous chemicals, and in particular to an emergency treatment device for leakage of hazardous chemicals. Background Art

[0002] Refineries involve a large number of hazardous chemicals in the production process, such as crude oil, natural gas, hydrogen, hydrogen sulfide, carbon monoxide, etc. These chemicals are flammable, explosive, toxic and harmful. Once leaked, they will cause serious harm to personnel, equipment, environment, etc. For example, the leakage of hazardous chemicals may cause casualties such as poisoning, suffocation, and burns. Leaked hazardous chemicals may pollute environmental media such as soil, water sources, and air, and have long-term effects on the ecological environment. The specific reasons for the leakage of hazardous chemicals are as follows: The equipment of refineries is complex and has been operating in harsh environments such as high temperature, high pressure, and corrosion for a long time, which can easily lead to equipment aging, damage or failure, thereby causing the leakage of hazardous chemicals. Operators may cause the leakage of hazardous chemicals due to improper operation, negligence or violation of operating procedures during the production process. There may be defects or deficiencies in the design stage of the refinery, such as improper equipment selection and unreasonable process flow, which may increase the risk of hazardous chemical leakage. Natural disasters such as earthquakes, floods, and typhoons may damage refinery facilities and cause hazardous chemical leakage.

[0029] Embodiment 1, as Figure 1 As shown, a hazardous chemical leakage emergency treatment device proposed by the present invention includes a leakage blocking frame 1, a purification cylinder 2 and a recovery cylinder 3 which are connected in sequence.

[0030] like Figure 2 The leakage plugging frame 1 includes a frame 101 which is detachably installed at the leakage site; a leakage plugging member 103, a sealing member 102 and a recovery member 104 are arranged on the mounting surface of the frame 101; the leakage plugging member 103 sprays refrigerant to cool and freeze the leakage site on the one hand, and covers the leakage site on the other hand to prevent the diffusion of gaseous hazardous chemicals; the sealing member 102 surrounds the leakage plugging member 103 and forms a seal by fitting with the leakage site; the recovery member 104 utilizes negative pressure adsorption to recover the leaked hazardous chemical gas.

[0031] like Figure 6 As shown, the purification cylinder 2 includes a cylinder body 201; a buffer chamber 202, a refrigeration chamber 208 and a purification chamber 203 are arranged in the cylinder body 201 from top to bottom, and a purification auxiliary component 209 is also arranged in the cylinder body 201, which runs through the buffer chamber 202, the refrigeration chamber 208 and the purification chamber 203; the buffer chamber 202 is connected to the recovery component 104 through a pipe 1 5; the refrigeration chamber 208 is connected to the leakage blocking component 103 through a pipe 2 4; a purification liquid is arranged in the purification chamber 203, and is connected to the recovery cylinder 3 through a pipe 3 6.

[0032] like Figure 3As shown, the frame 101 is a U-shaped structure, which is connected to the pipeline by snap-fitting, and a handle 105 is provided on the outer wall; the recovery member 104 is located on both sides of the outer wall of the frame 101; the leakage plugging member 103 is located at the top of the inner wall of the frame 101; the sealing member 102 is provided along the inner wall of the frame 101 and extends to the outside of the frame 101.

[0033] When a hazardous chemical leaks from a pipeline, it will be detected by nearby leak sensing equipment and a leak warning will be issued to the staff. Before the maintenance personnel arrive, the nearby staff can clamp the frame 101 on the leaking pipeline to carry out emergency treatment.

[0034] like Figure 3-Figure 4 As shown, the leakage plugging component 103 includes a leak-proof cover 10301; the leak-proof cover 10301 is arc-shaped, the convex surface of the leak-proof cover 10301 fits with the concave surface of the frame 101, and the concave surface of the leak-proof cover 10301 is open; the nozzle 10302 is located at the top of the leak-proof cover 10301, and sprays refrigerant toward the open mouth; the leakage sensor 10303 is located on the side wall of the leak-proof cover 10301.

[0035] It should be further explained that multiple groups of leakage sensors 10303 are arranged along the side wall of the leak-proof cover 10301 and correspond one-to-one to the nozzles 10302.

[0036] It should be further explained that a refrigeration pipe 106 is arranged inside the frame 101; the refrigeration pipe 106 is connected to the nozzle 10302 and the refrigeration chamber 208 through a pump 1 and a pipe 15.

[0037] The refrigeration chamber 208 is used to store refrigerant, which is set as dry ice here; when performing emergency treatment of hazardous chemical leakage, the leakproof cover 10301 covers the pipeline to form a sealed space. The leakage sensor 10303 detects the pressure changes at different positions to determine the leakage position. The nozzle 10302 at the corresponding position sprays refrigerant, which can cool the pipeline and oil and reduce the safety hazards caused by high temperature. At the same time, it can reduce the fluidity and volatility of hazardous chemicals, prompting the oil components therein to freeze to block the leak, avoid further leakage, and buy more time for maintenance personnel.

[0038] like Figure 3-Figure 4 As shown, the recovery member 104 is a telescopic tube rotatably arranged on the outer wall of the frame 101; a recovery pipe 107 is arranged inside the frame 101; the recovery pipe 107 is connected to the telescopic tube and the buffer chamber 202 through a pump 2 and a pipe 2 4.

[0039] Since the recovery part 104 is a rotatable and retractable pipe, the position of the pipe mouth of the retractable pipe can be adjusted according to the position of the leaked hazardous chemicals, so that the leaked hazardous chemicals can be recovered in a targeted manner to avoid further spread of the hazardous chemicals.

[0040] It should be further explained that the frame 101, the recovery pipe 107 and the refrigeration pipe 106 are all made of cold-conducting metal material; the recovery parts 104 correspond to the two sides of the frame 101, with two groups arranged on one side; two groups of recovery pipes 107 are arranged, located on both sides of the refrigeration pipe 106, and at the same time, the two ends of each group of recovery pipes 107 are respectively connected to the recovery parts 104 on both sides.

[0041] It should be further explained that the recovery pipe 107 and the refrigeration pipe 106 are arc-shaped pipes arranged in parallel.

[0042] It should be further explained that the frame 101 is provided with four sets of leakage sensors 108 located at the front, back, left and right sides corresponding to the four sets of recovery components 104 .

[0043] The leakage sensor 108 detects the location where the concentration of leaked gas is high, and the staff adjusts the recovery part 104 to the corresponding position for targeted recovery. When the refrigeration pipe 106 circulates the refrigerant, the recovery pipe 107 simultaneously recovers the leaked hazardous chemicals. Both circulate in the frame 101 at the same time. The refrigerant can cool the frame 101 and the hazardous chemical gas. Cooling the frame 101 and the hazardous chemicals can reduce the risk of leakage, diffusion, explosion, and combustion.

[0044] like Figure 5 As shown, the seal 102 includes a flexible adhesive tape 10201; the flexible adhesive tape 10201 is configured as a U-shaped structure that fits the concave surface of the frame 101, a through groove 10202 surrounding the leak-proof cover 10301 is provided in the middle, and notches 10203 are provided at both ends to form two extended adhesive strips extending out of the frame 101.

[0045] It should be further explained that an adhesive layer is provided on the surface of the flexible adhesive tape 10201.

[0046] It should be further explained that a release layer is provided on the surface of the adhesive layer.

[0047] In case of emergency, the release layer needs to be torn off, and when the leak-proof cover 10301 covers the leak, the flexible adhesive tape 10201 simultaneously adheres to the outer wall of the pipe. Then the staff will extend the adhesive layer and wrap it around the pipe along the length of the pipe to further seal it, so as to reduce the spread of the leak and buy time for repair.

[0048] like Figure 6-Figure 8As shown, an upper partition plate 207 is provided in the cylinder 201 to separate the buffer chamber 202 and the refrigeration chamber 208, and a lower partition plate 210 is provided to separate the refrigeration chamber 208 and the purification chamber 203; the upper partition plate 207 and the lower partition plate 210 are both provided with corresponding and connected through holes; the refrigeration channel 211 passes through the refrigeration chamber 208, and the two ends are respectively fixed in the upper and lower through holes. A pressure regulating plate 205 is provided in the buffer chamber 202; a pressure regulating chamber is provided above the pressure regulating plate 205; the pressure regulating device 204 pressurizes / depressurizes the pressure regulating chamber to drive the pressure regulating plate 205 to move up and down.

[0049] It should be further explained that a buffer spring 206 is also provided in the pressure regulating chamber to act on the pressure regulating plate 205 .

[0050] It should be further explained that the leakage blocking member 103 is a retractable structure, the upper end of which is connected to the pressure regulating plate 205 , and the lower end of which penetrates the refrigeration channel 211 and is connected to the purification chamber 203 .

[0051] When the recovered leaked hazardous chemical gas enters the buffer chamber 202, the pressure regulating plate 205 moves up and down through the pressure change in the pressure regulating chamber. The recovered hazardous chemicals are pressurized by the lifting and lowering of the pressure regulating plate 205, which makes them pass through the refrigeration channel 211, and at the same time, the leakage blocking member 103 can be extended and retracted. The leakage blocking member 103 can dredge the refrigeration channel 211 by extending and retracting, and can stir the purified liquid by extending and retracting.

[0052] like Figure 6-Figure 9 As shown, the leakage plugging member 103 includes a mounting seat 20901 connected to the pressure regulating plate 205, a telescopic rod 20902 connected to the bottom of the purification chamber 203, and a dredging rod 20903 connecting the two. An adsorbent is arranged in the refrigeration channel 211; the dredging rod 20903 penetrates the refrigeration channel 211, and a dredging frame 20908 is arranged along the length direction of the refrigeration channel 211.

[0053] It should be further explained that the adsorbent is activated carbon particles; the dredging rack 20908 is set in a "cross" structure. When the hazardous chemical gas passes through the activated carbon bed, the organic pollutants are adsorbed by the micropores on the surface of the activated carbon, thereby achieving gas purification.

[0054] When the pressure regulating plate 205 rises and falls, the telescopic rod 20902 is synchronously extended and retracted, the dredging rod 20903 moves up and down in the refrigeration channel 211, and the dredging frame 20908 stirs the adsorbent. On the one hand, it promotes the circulation and refrigeration of the recovered hazardous chemicals, and on the other hand, it ensures the adsorption effect.

[0055] like Fig.10As shown, multiple groups of telescopic rods 20902 are arranged, one group is located in the center, and the remaining groups of telescopic rods 20902 are arranged around the central group of telescopic rods 20902; the stirring outer ring 20904 is sleeved on the telescopic section of the peripheral telescopic rod 20902; the stirring inner ring 20906 is located on the telescopic section of the central telescopic rod 20902; the stirring outer ring 20904 and the stirring inner ring 20906 are connected by a stirring rod 20907 to form a stirring structure for mixing the purified liquid.

[0056] It should be further explained that a leakage hole 20905 is provided on the stirring outer ring 20904 for the purification liquid to flow.

[0057] When the pressure regulating plate 205 rises and falls, the telescopic rod 20902 is synchronously extended and retracted, and the stirring structure is synchronously moved up and down, driving the purified liquid to shake, mixing the purified liquid and the recovered hazardous chemicals, and promoting the purification effect of the purified liquid.

[0058] like Fig.11 As shown, a spray head 213 is arranged on the hole wall of the lower through hole; the spray head 213 absorbs the purified liquid through the suction pipe 212 and the pump, and then sprays it from the lower through hole, so that the effect of hazardous chemicals and the purified liquid is more thorough and comprehensive.

[0059] Common purification liquids in refineries include oil-water separators, demulsifiers, and hydrogen sulfide gas leakage removers. Oil-water separators are mainly used to treat oil leakage in refineries, separating oil and water by physical or chemical methods to achieve the purpose of purifying the environment. This type of purifier usually has good emulsification, dispersion and flocculation properties, and can effectively separate leaked oil substances from water. Demulsifiers are mainly used to treat emulsified oil leakage in refineries. Demulsifiers can destroy the stability of emulsified oil and decompose it into oil and water, which is convenient for subsequent treatment. Hydrogen sulfide gas leakage removers can react with leaked hydrogen sulfide gas, reduce and control its diffusion speed and range, and win precious time for emergency rescue and evacuation of personnel in the leakage area. The choice of purification liquid can be selected according to the actual distribution of hazardous chemicals in the refinery.

[0060] The purified waste gas and waste liquid mixture is transferred to the recovery tube 3 and discharged after further processing and testing. The recovery tube 3 can be set in multiple groups and stored uniformly on the base for emergency use.

[0061] Embodiment 2: Based on the hazardous chemical leakage emergency treatment device in Embodiment 1, this embodiment proposes an emergency treatment method for hazardous chemical leakage, and the steps are as follows:

[0062] S1. The leak sensing device detects a hazardous chemical leak in a certain section of the pipeline and issues a leak warning to the staff;

[0063] S2. The staff nearby tears off the release layer and clamps the frame 101 on the leaking pipe; the leak-proof cover 10301 covers the leaking part, and the flexible adhesive tape 10201 adheres to the outer wall of the pipe at the same time; then the staff extends the adhesive layer and wraps it around the pipe along the length of the pipe to further seal it;

[0064] S3, the leakage sensor 10303 determines the leakage position; the nozzle 10302 at the corresponding position sprays refrigerant to cool down the pipeline and hazardous chemicals; the leakage sensor 2 108 detects the position with a high concentration of leaked gas, and the staff rotates and adjusts the recovery unit 104 to the corresponding position for targeted recovery;

[0065] S4, the refrigeration pipe 106 performs refrigeration, and the recovery pipe 107 recovers the leaked hazardous chemicals simultaneously; the hazardous chemicals are cooled down once by the cooling;

[0066] S5, hazardous chemicals enter the buffer chamber 202; the pressure regulating plate 205 rises and falls, the telescopic rod 20902 is synchronously extended and retracted, the dredging rod 20903 moves up and down in the refrigeration channel 211, and the dredging frame 20908 stirs the adsorbent; the hazardous chemicals are pressurized and pass through the refrigeration channel 211; the refrigerant in the refrigeration chamber 208 cools the hazardous chemicals for a second time;

[0067] S6, after the spray head 213 absorbs the purification liquid, it sprays from the through hole below to purify the hazardous chemicals;

[0068] S7, the hazardous chemicals enter the purification chamber 203, and the stirring structure moves synchronously with the rise and fall of the pressure regulating plate 205, driving the purification liquid to shake, promoting the mixing of the purification liquid and the hazardous chemicals, and performing secondary purification treatment on the hazardous chemicals;

[0069] S8. The purified waste gas and waste liquid mixture is transferred to the recovery cylinder 3 and discharged after further treatment and detection.

[0070] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
