Description

Technical Field

[0001] The present invention relates to the technical field of hazardous liquid chemical leakage disposal, and in particular to emergency rescue equipment for harmlessly disposing of large-scale organic liquid hazardous chemical leakage accidents. Background Art

[0002] During the production, storage, transportation, and use of petrochemicals and hazardous chemicals, leakage may occur for various reasons, thus causing liquid hazardous chemical accidents. Liquid hazardous chemicals are flammable, explosive, toxic, corrosive, and so on. After a liquid hazardous chemical leakage accident occurs, it is very easy to cause great harm to personnel, facilities, and the environment. Liquid hazardous chemical accidents are sudden, urgent, complex, and highly lethal. Therefore, they are extremely difficult to handle. Once they are handled improperly or not in time, chain accidents such as fire and explosion are very likely to occur.

[0003] After a liquid hazardous chemical accident occurs, rapid and correct disposal of the leaked material can effectively prevent secondary disasters such as fire, explosion, poisoning, and environmental pollution, and reduce the harm. However, the existing technology for handling liquid hazardous chemical disasters has the defects of low emergency disposal efficiency and large casualties. The core reason is that it is impossible to completely suppress the volatilization of harmful gases, making it difficult to prevent secondary disasters such as fire, explosion, and poisoning.

[0004] In the prior art, in order to intercept the flow of liquid hazardous chemicals after an accident occurs, the main means used are dike blocking, dilution covering and adsorption. However, these methods are inefficient, ineffective and cannot fundamentally suppress the volatilization of hazardous chemicals.

[0005] For example, the dike interception method requires rescue workers to build dikes and dig pits according to the on-site conditions, which is time-consuming and labor-intensive, has a poor interception effect, is prone to leakage, and cannot control the flow and spread of liquid, causing the scope of the accident to expand.

[0006] For example, the dilution covering and adsorption methods, in order to suppress the volatilization of toxic and harmful gases, the current technology used is to cover with foam, sand or use absorbent materials such as oil absorbent felt. These disposal technologies can only reduce the volatilization rate of liquid chemicals, but cannot change the flow characteristics of the liquid, and cannot effectively suppress the volatilization of hazardous chemicals. The volatilized flammable and explosive / toxic gases are very likely to cause fires and explosions, thereby expanding the scope of the accident and the disposal efficiency is low. After the accident is handled, it is easy to re-ignite, which has an impact on the environment. Due to the continued existence of the volatilization state of the leaked material, the flammable and explosive / toxic gases will continue to cause disasters; if the leaked material and foam are not removed in a timely and effective manner, it may cause serious environmental pollution.

[0007] Patent CN212067515U discloses a cart-type organic liquid hazardous chemical leakage disposal device, which can be filled with dozens of kilograms of absorbent and can handle leakage of typical organic liquid hazardous chemicals such as hundreds of liters of gasoline. However, for slightly larger-scale hazardous liquid chemical leakage accidents, such as tank rupture and leakage accidents of hazardous chemical tank trucks, the disposal capacity of the device is obviously insufficient. On the other hand, the patent is equipped with a handheld spray gun, which requires emergency rescue personnel to spray chemicals at close range to deal with the accident. Due to the complex situation on the scene, there are a large number of flammable, explosive or toxic and harmful gases, as well as many unsafe behaviors of people and unsafe factors of things, which can easily cause secondary disasters and endanger personal and property safety.

[0008] In summary, existing technologies have problems such as insufficient disposal capacity, insufficient safety assurance capabilities, and easy to cause secondary disasters. There is an urgent need for large-scale equipment that can harmlessly dispose of liquid hazardous chemical leaks and effectively suppress secondary disasters. Summary of the invention

[0009] The purpose of the present invention is to solve the problems existing in the prior art such as insufficient disposal capacity for liquid hazardous chemical leakage, insufficient safety assurance capacity, and easy to cause secondary disasters. The present invention provides a large-scale equipment for harmlessly disposing of liquid hazardous chemical leakage, which can achieve harmless disposal, has strong disposal capacity, high operating safety, and can effectively suppress secondary disasters caused by large-scale liquid hazardous chemical leakage accidents.

[0010] In order to achieve the above-mentioned purpose, the present invention specifically adopts the following technical solutions:

[0011] In a first aspect, the present invention provides a large-scale equipment for handling leakage of liquid hazardous chemicals, the equipment comprising a supply system, a spraying terminal and a conveying pipeline assembly connected between the supply system and the spraying terminal; the supply system is provided with an absorbent filling assembly, an inhibitor filling assembly and an air compression assembly, all of which are connected to the conveying pipeline assembly.

[0012] Furthermore, the delivery pipeline assembly includes an absorbent delivery pipeline connected to the absorbent filling assembly, an inhibitor delivery pipeline connected to the inhibitor filling assembly, and a compressed air delivery pipeline connected to the air compression assembly, and the delivery pipelines are all flexible pressure-resistant hoses.

[0013] Furthermore, the absorbent filling assembly includes a powder storage device and a powder filling device connected to the powder storage device, and the outlet end of the powder filling device is connected to the absorbent delivery pipeline.

[0014] Furthermore, the inhibitor filling assembly includes an aqueous solution storage device and a booster pump connected to an outlet end of the aqueous solution storage device, and the booster pump is connected to the inhibitor delivery pipeline.

[0015] Furthermore, the air compression component includes an air compressor connected to the compressed air delivery pipeline, and the air compressor is used to generate compressed air to provide spraying power for the spraying terminal.

[0016] Furthermore, the supply system also includes a carrier for installing the absorbent filling component, the inhibitor filling component and the air compression component, and the carrier can be a car, a trailer, a ship or an integrated skid.

[0017] Furthermore, the spraying terminal is an explosion-proof self-propelled robot, which is used by rescue workers to remotely control its walking, spraying of agents and real-time transmission of on-site video images.

[0018] Furthermore, the explosion-proof self-propelled robot is provided with an absorbent spraying device and an inhibitor spraying device, and the absorbent spraying device and the inhibitor spraying device are used to turn on or off the spraying of the agent and adjust the spraying direction.

[0019] Compared with the prior art, the advantages of the present invention are:

[0020] 1. The present invention relates to a large-scale equipment for handling leakage of liquid hazardous chemicals. By setting a connection structure of a supply system, a spraying terminal, and a conveying pipeline component, three major module components connected to the spraying terminal are set in the supply system, namely: an absorbent filling component, an inhibitor filling component, and an air compression component. The absorbent filling component cooperates with the spraying terminal to realize the long-distance transportation and spraying of the absorbent, the inhibitor filling component cooperates with the spraying terminal to realize the long-distance transportation and spraying of the inhibitor, and the air compression component generates compressed air to provide spraying power for the spraying terminal, forming a complete set of large-scale equipment for liquid hazardous chemical leakage accidents. When handling large-scale liquid hazardous chemical leakage accidents, emergency rescue personnel only need to connect the supply system with the spraying terminal by installing and connecting the conveying pipeline component to carry out emergency rescue work safely and conveniently. It can achieve harmless disposal, has strong disposal capacity, high operational safety, and can effectively suppress secondary disasters of large-scale liquid hazardous chemical leakage accidents, filling the technical gap in the existing technology of lack of emergency rescue equipment for harmless disposal of large-scale liquid hazardous chemical leakage accidents.

[0021] By setting up absorbent filling components and inhibitor filling components, a large amount of reagents can be carried in the supply system, which can efficiently handle and effectively suppress secondary disasters.

[0022] By setting up an intelligent explosion-proof spraying terminal, emergency rescue personnel can enter the dangerous scene for close-range operations instead, reducing the unsafe behavior of rescue personnel. The explosion-proof spraying terminal can minimize the unsafe factors of objects, thereby achieving safer emergency rescue disposal. The overall system is intelligent and safe.

[0023] By setting up air compression components and using compressed air to power the spraying terminal of the supply system, unsafe factors such as cable damage and electrical short circuit caused by using high-power power drive in complex environments are avoided, and unsafe factors such as hydraulic oil leakage caused by using hydraulic drive are also avoided. The equipment itself has a higher safety guarantee capability, and even if the delivery pipeline is damaged during the travel process, no secondary disaster will occur. The safety of the complete set of equipment is further improved. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0029] The present invention provides a large-scale equipment for handling leakage of liquid hazardous chemicals.

[0030] It can be understood that the use and working process of this large-scale equipment is as follows: since the hazardous chemical leakage site is prone to the accumulation of flammable, explosive and toxic and harmful gases, personnel and the non-explosion-proof supply system 1 cannot enter the site. The supply system 1 can only be parked in a safe area, and then the emergency rescue connects the explosion-proof delivery pipeline assembly 3 to the spraying terminal 2 of the supply system 1, and the supply system 1 transports the agent over a long distance, and the spraying terminal 2 of the supply system 1 goes deep into the accident site to spray the agent.

[0031] It should be noted that the large-scale equipment for handling liquid hazardous chemical leakage of the present invention is provided with a connection structure of a supply system 1, a spraying terminal 2, and a conveying pipeline assembly 3, and three module assemblies connected to the spraying terminal 2 are provided in the supply system 1, an absorbent filling assembly, an inhibitor filling assembly and an air compression assembly.

In an emergency, emergency rescue only needs to quickly connect the conveying pipeline assembly 3 to connect the supply system 1 with the spraying terminal 2. The overall structure is relatively simple, the operation is convenient, and it has strong advantages. It can realize harmless disposal, has strong disposal capacity, high operational safety, and can effectively suppress the secondary disasters of large-scale liquid hazardous chemical leakage accidents, filling the technical gap of the lack of emergency rescue equipment for harmless disposal of large-scale liquid hazardous chemical leakage accidents in the prior art.

[0032] By setting up absorbent filling components and inhibitor filling components, a large amount of medicine can be carried in the supply system 1, which can efficiently handle and effectively suppress secondary disasters. By setting up an intelligent spraying terminal 2, it can replace manpower to enter the dangerous site for front-line operations, achieve safer spraying operations, and the overall system is intelligent and safe. By setting up an air compression component, compressed air is used to provide power for the spraying terminal 2 of the supply system 1, avoiding the use of high-power power supplies, and having better explosion-proof performance.

The outlet end of the powder filling device 6 is connected to the absorbent delivery pipeline.

[0036] Specifically, in some embodiments, the powder storage device 4 is preferably a safe and durable powder tank. The powder filling device 6 is used to fill the medicine in the powder storage device 4 and spray it to the spraying terminal 2 over a long distance through the absorbent delivery pipeline.

[0037] In some embodiments of the present invention, please continue to refer to Figure 1 The inhibitor filling assembly includes an aqueous solution storage device 5 and a booster pump 7 connected to the outlet end of the aqueous solution storage device 5, and the booster pump 7 is connected to the inhibitor delivery pipeline.

[0038] Specifically, in some embodiments, the liquid medicine storage device 5 is preferably a safe and durable liquid medicine tank. The air compression component is preferably an air compressor 8.

[0039] Specifically, the aqueous storage device 5 stores a pre-prepared inhibitor, and the outlet of the aqueous storage device 5 is connected to the booster pump 7. The booster pump 7 pressurizes the inhibitor, and realizes long-distance transportation of the inhibitor through the inhibitor delivery pipeline, and finally combines with the power provided by the air compressor 8 to realize long-distance spraying of the inhibitor to the spraying terminal 2.

[0040] In some embodiments of the present invention, please continue to refer to Figure 1 The air compression component includes an air compressor 8 connected to the compressed air delivery pipeline, and the air compressor 8 is used to generate compressed air to provide spraying power for the spraying terminal 2. By setting up the air compression component and using compressed air to provide power for the spraying terminal of the supply system, unsafe factors such as cable damage and electrical short circuit caused by using high-power power drive in complex environments are avoided, and unsafe factors such as hydraulic oil leakage caused by using hydraulic drive are also avoided. The equipment itself has a higher safety guarantee capability, and even if the delivery pipeline is damaged during the walking process, no secondary disaster will occur. The safety of the complete set of equipment is further improved.

[0041] In some embodiments of the present invention, please continue to refer to Figure 1 The supply system 1 further comprises a carrier 9 for installing an absorbent filling component, an inhibitor filling component and an air compression component. The carrier 9 can be a car, a trailer, a ship or an integrated skid. In some specific embodiments, please refer to Figure 2 , the carrier 9 is a car.

[0042] In some embodiments of the present invention, the spraying terminal 2 is an explosion-proof self-propelled robot, which is used by rescuers to remotely control its walking, spraying of agents and real-time transmission of on-site video images. By setting up an intelligent explosion-proof spraying terminal, emergency rescue personnel can be replaced to enter dangerous sites for close-range operations, reducing unsafe behaviors of rescue personnel.

The emergency rescue starts the powder filling device 6 and the booster pump 7, and delivers the medicine in the powder storage device 4 and the water storage device 5 to the spraying terminal 2 of the supply system 1 through the pipeline. Then the air compressor 8 in the supply system 1 is started, and the compressed air delivery pipeline of the air compressor 8 provides spraying power for the spraying terminal 2.

[0045] Then the emergency rescue remote control spraying terminal 2 (preferably an explosion-proof self-propelled robot) walks to the accident site and first sprays the absorbent to quickly absorb and solidify the organic liquid hazardous chemicals to prevent them from flowing and spreading. Subsequently, the inhibitor is sprayed to form a protective film to inhibit the volatilization process, so that rapid and effective emergency disposal can be completed to achieve the best treatment effect.
