Description

Technical Field

[0001] The invention relates to the technical field of energy equipment manufacturing, and in particular to a hydrocarbon and liquid ammonia emergency rescue mobile skid-mounted system and a use method thereof. Background Art

[0002] Liquid ammonia and flammable and explosive substances such as hydrocarbons including LPG, propane, propylene and butane are generally stored in room temperature liquid tank trucks for road transportation. If a serious traffic accident occurs along the way, it is easy to overturn and leak. If there is no special equipment to export the medium inside the tank truck, the internal hazardous substances can generally only be released. This process takes several days and a lot of manpower and material resources, occupies highway lane space, and faces the risk of combustion or even explosion. Once an accident occurs, it will cause great losses. In addition, on-site emissions cause serious pollution to the soil, water quality and other environments, and on-site ignition causes pollution to the atmosphere. An emergency equipment is urgently needed to guide the hazardous substances in the accident tank truck into a safe empty tank truck to prevent danger and serious damage to the ecological environment. Summary of the invention

[0003] The purpose of the present invention is to provide a mobile skid-mounted system for emergency rescue of hydrocarbons and liquid ammonia and a method for using the same, so as to reduce the risk of hydrocarbon and liquid ammonia material transfer.

[0004] To achieve the above object, the present invention provides the following solutions:

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] The purpose of the present invention is to provide a mobile skid-mounted system for emergency rescue of hydrocarbons and liquid ammonia and a method for using the same, so as to reduce the risk of hydrocarbon and liquid ammonia material transfer.

[0028] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] refer to Figure 1A mobile skid-mounted system for emergency rescue of hydrocarbons and liquid ammonia, comprising a compressor, a gas phase hose arranged at both ends of the compressor and connected to the compressor, a pump body, and a liquid phase hose arranged at both ends of the pump body and connected to the pump body. The pump body and the compressor are both provided with infrared locators, the gas phase hose is respectively connected to an accident tank truck and a rescue tank truck, the liquid phase hose is respectively connected to an accident tank truck and a rescue tank truck, the infrared locator is used to locate the accident tank truck and make the distance between the pump body and the compressor and the accident tank truck greater than 15m; in the present invention, the compressor and the pump body are organically integrated, and the positions of the compressor and the pump body are accurately located by the infrared locator, so that the compressor and the pump body are operated in an area away from the accident tank truck, and the ignition source is kept away from the accident area to avoid explosion and ensure the personal safety of operators.

[0030] Furthermore, when the tank truck overturns in an accident, the pressure inside the tank truck decreases as the gas or liquid is pumped out. At this time, the saturated gasification temperature of the medium also decreases, forming a certain temperature difference with the ambient temperature outside the tank body at normal temperature. Through temperature difference heat exchange, the medium is continuously gasified and replenished, so that the pressure inside and outside the tank body is always kept in a balanced state, and the gas and liquid are extracted cleanly; in addition, when the external ambient temperature is too low, it is only necessary to spray the tank body with fire water to prevent the tank body temperature from being too low. If the ambient temperature is high, the compressed gas enters the normal tank truck, and the pressure will continue to rise. At this time, fire water spraying is required to reduce the temperature of the outer wall of the tank body, so that the internal medium is cooled and condensed, thereby reducing the pressure of the tank truck. Therefore, there is no negative pressure inside the tank body, and it will not affect the outflow of the fluid in the tank body.

[0031] Furthermore, the connection status of the gas phase pipeline and the liquid phase pipeline are respectively sealed with the gas phase pipeline interface and the liquid phase pipeline interface of the accident tank truck. Furthermore, when the gas phase pipeline interface is covered by the liquid phase, the liquid phase is extracted first, and when the liquid phase is extracted to the point where the gas phase pipeline interface is exposed, the gas phase can be extracted.

[0032] Furthermore, the pump body is a high-pressure liquid pump, the high-pressure liquid pump adopts a balanced mechanical seal, and the compressor is a reciprocating piston compressor; the pump body adopts a high-pressure liquid pump, which replaces the traditional explosion-proof motor as a power source to further avoid the risk of generating electric sparks or open flames.

[0033] refer to Figure 1 Both ends of the high-pressure liquid pump connected to the liquid phase hose and both ends of the compressor connected to the gas phase hose are provided with female connectors, and one end of the liquid phase hose connected to the high-pressure liquid pump and one end of the gas phase hose connected to the compressor are provided with male connectors; this can facilitate operators to quickly install and disassemble, thereby saving time.

[0034] Furthermore, both the male connector and the female connector are quick connectors.

[0035] refer to Figure 1 The ends of the liquid phase hose and the gas phase hose connected to the accident tank truck and the rescue tank truck are both provided with container tank adapters, and the end of the container tank adapter away from the liquid phase hose or the gas phase hose is connected to the accident tank truck or the rescue tank truck.

[0036] refer to Figure 1 An H-type connector is provided between the liquid phase hose and the gas phase hose, and two parallel sides of the H-type connector are respectively provided on the liquid phase hose and the gas phase hose and are respectively connected with the liquid phase hose and the gas phase hose, and one side of the H-type connector perpendicular to the parallel sides is respectively connected with the parallel sides and a valve is provided on the side.

[0037] Furthermore, the liquid phase hose and the gas phase hose are connected to the H-type connector through a male connector and a female connector.

[0038] Furthermore, a slidable base is provided at the bottom of the compressor and the pump body.

[0039] Furthermore, the slidable base includes a bottom plate and universal wheels arranged on the bottom plate.

[0040] Furthermore, the compressor and pump body outer cover protective container is placed on a double-row truck and can quickly reach the accident site.

[0041] A method for using a mobile skid-mounted system for emergency rescue of hydrocarbons and liquid ammonia, comprising the following steps:

[0042] Turn on the infrared locators on the compressor and the pump body to locate the accident tanker, and move the compressor and the pump body to an area 15 meters away from the accident tanker;

[0043] Connect the accident tanker and the rescue tanker via a gas phase hose and a liquid phase hose;

[0044] When liquid phase transfer is required, just open the pump body to complete the liquid transfer;

[0045] When gas phase transfer is required, when the gas phase pipeline interface is covered by the liquid phase, first extract the liquid phase. When the gas phase pipeline interface is exposed, turn on the compressor to complete the gas transfer.

[0046] When both gas phase transfer and liquid phase transfer are required, when the gas phase pipeline interface is covered by the liquid phase, the liquid phase is extracted first. When the gas phase pipeline interface is exposed to the liquid surface, the compressor and the pump body can be opened at the same time to transfer the gas and liquid phases. When both the gas phase and liquid phase pipeline interfaces are exposed to the liquid surface, only the compressor can be opened for gas phase transfer. As the gas pressure in the accident tank truck decreases, liquid hydrocarbons or liquid ammonia can continue to absorb heat and vaporize until the liquid and gas in the accident tank truck are drained.
