Description

Technical Field

[0001] The utility model belongs to the technical field of fire fighting, and more specifically, relates to a methanol storage tank fire fighting system based on an electric three-way valve. Background Art

[0002] Since the sewage treatment plant needs to provide a certain carbon source to microorganisms to meet their production needs during the sewage treatment process, some treatment plants will choose methanol as the carbon source. However, due to maintenance, reconstruction, and new construction, sewage treatment plants may involve operations such as open flames and temporary electricity that may produce open flames or sparks. At the same time, methanol is a highly volatile and flammable liquid, which may cause fire and explosion accidents. Therefore, it is necessary to set up fire protection measures for the methanol addition system and conduct fire drills regularly.

[0003] The manual two-way valve fire-fighting system currently used in sewage treatment plants has fire prevention functions, but some valves are manual valves and cannot be opened remotely. At the same time, due to the limitations of the two-way valve, firstly, the foam generated by the foam generator in the existing fire-fighting system directly enters the methanol pipe through the foam pipeline without a fork, which is not conducive to practical exercises and production operations; secondly, it is impossible to observe whether the fire-fighting foam entering the foam pipeline is successfully foamed. Utility Model Content

[0004] The purpose of the utility model is to address the deficiencies in the prior art and to provide a methanol storage tank fire extinguishing system based on an electric three-way valve. The fire extinguishing system is easy to operate and does not affect production operations, and can prevent fire foam from entering the methanol storage tank during practical exercises.

[0017] The utility model provides a methanol storage tank fire fighting system based on an electric three-way valve, and its beneficial effects are: the fire fighting system is provided with a three-way valve between a fire fighting foam storage unit and a methanol storage tank, and during a fire drill, a quick connector can be connected to a connecting hose, so that the fire fighting foam can be directly output without affecting the normal operation of the methanol storage tank; in addition, when a fire occurs, the fire fighting foam can be delivered into the methanol storage tank through the second outlet of the three-way valve, thereby eliminating safety hazards and reducing the possibility of fire and explosion accidents.

[0026] The preferred embodiments of the present invention will be described in more detail below. Although the preferred embodiments of the present invention are described below, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.

[0027] The utility model provides a methanol storage tank fire fighting system based on an electric three-way valve, comprising:

[0028] A three-way valve, the inlet of which is connected to the fire foam storage unit, the first outlet of the three-way valve is connected to the methanol storage tank, and the second outlet of the three-way valve is the output end of the emergency drill fire foam;

[0029] A control unit is connected to the three-way valve control.

[0030] Specifically, the fire fighting system is provided with a three-way valve between the fire fighting foam storage unit and the methanol storage tank. The three-way valve is used to control the outflow direction of the fire fighting foam. During the transportation process, the three-way valve introduces the foam liquid of the fire fighting foam storage unit, and the control unit is used to select the first outlet or the second outlet to discharge the foaming foam. When a fire drill is required, the three-way valve can be switched to the second outlet to discharge the foaming foam, so that the foam will not enter the methanol storage tank and will not affect the normal production operation. When a fire occurs, the three-way valve can be switched to the first outlet to discharge the foaming foam, so that the foam enters the methanol storage tank to achieve the purpose of fire prevention and extinguishing. In addition, if you want to observe the foaming of the foam, you can also switch the three-way valve to the second outlet to discharge the foam.

[0031] Optionally, the fire-fighting foam storage unit includes a fire-fighting foam liquid storage tank and a foam generator, with a first fire-fighting pipeline arranged therebetween.

[0032] Specifically, in the fire foam storage unit, the fire foam liquid is sent from the storage tank to the foam generator through the first fire pipe, so that the fire liquid is foamed, and then the foamed fire foam is transported to the three-way valve, and the opening method of the three-way valve is adjusted as needed.

[0033] Optionally, an electric valve is provided on the first fire-fighting pipeline.

[0034] Specifically, whether it is a fire drill or a fire, the control unit needs to select the connection mode of the three-way valve, connect the first outlet or the second outlet with the inlet, and then start the electric valve, so that fire foam can be generated and output from the designated outlet. The control unit is connected to the electric valve, and the opening mode of the electric valve and the three-way valve forms a variety of opening modes, so that the needs can be met by operating the control unit, and the fire fighting system is more intelligent and easier to operate.

[0035] Optionally, a quick connector is provided on the second outlet of the three-way valve.

[0036] Optionally, the quick connector and the connecting hose are detachably connected.

[0037] Specifically, the second outlet of the three-way valve is connected to the connecting hose through a quick connector for use in fire drills. During actual drills, the fire foam is output from the connecting hose, which can prevent the foam from directly entering the methanol storage tank and affecting production operations. The connecting hose can be disassembled at any time and will not affect the surrounding environment.

[0038] In one embodiment, the link hose may be a foam hose.

[0039] Optionally, a second fire-fighting pipeline is provided between the three-way valve and the methanol storage tank.

[0040] Optionally, the three-way valve is made of stainless steel.

[0041] Specifically, the three-way valve is made of stainless steel, and the pipe wall thickness is set to be relatively thick, so that it can have certain corrosion resistance and resistance to smashing and deformation.

[0042] Optionally, the control unit is a remote control terminal.

[0043] Specifically, a remote control terminal is used to control the three-way valve. The remote control terminal can be wirelessly connected to a display screen, a storage unit, and a playback unit. The wireless connection facilitates remote control of the display screen, the storage unit, and the playback unit, thereby improving the intelligent operation of the fire protection system.

[0044] Optionally, the methanol storage tank is connected to at least two three-way valves, and each three-way valve is respectively connected to a fire-fighting foam storage unit.

[0045] Specifically, in order to ensure that the explosion hazard of the methanol storage tank is eliminated as soon as possible when a fire occurs, multiple three-way valves are connected to the methanol storage tank. The number of three-way valves opened is controlled according to the size of the fire to ensure production safety. When a three-way valve or foam generator fails, the foamed firefighting foam can be sent to the methanol storage tank through other three-way valves that are operating normally.

[0046] Optionally, the firefighting foam liquid in the firefighting foam storage unit is a non-temperature sensitive foam liquid.

[0047] Specifically, the fire-fighting foam liquid needs to be stable, non-toxic and non-corrosive. Therefore, using non-temperature-sensitive foam liquid as the fire-fighting foam liquid can avoid corrosion to the foam generator and pipelines and is not affected by freezing and melting.
