Description

TECHNICAL FIELD

[0001] The application relates to the technical field of fire extinguishing, in particular to a solvent equipment explosion-proof and fire extinguishing device. BACKGROUND

[0002] The solvent equipment has flammable solvents inside, in order to prevent the solvent equipment from catching fire, the solvent equipment usually needs to be provided with a fire extinguishing device, for example, a carbon dioxide fire extinguisher. The solvent equipment has an exhaust pipe, and in the prior art, the exhaust of the solvent equipment is only provided with a manual air valve and is not linked with the fire extinguishing device. After the fire extinguishing medium is released, the exhaust quickly sucks away the fire extinguishing medium, so that the fire extinguishing effect is poor. Secondly, in the prior art, a single type of sensor is usually used to detect a fire, for example, one or two high-temperature sensors. When any high-temperature sensor is triggered, the fire extinguishing medium is released. The signal of the single type of sensor is prone to false reporting of a fire due to signal interference. CONTENT OF THE UTILITY MODEL

[0003] The application aims to overcome the problems of poor fire extinguishing effect and easy false reporting of a fire due to loss of fire extinguishing medium in the prior art, and provides a solvent equipment explosion-proof and fire extinguishing device.

[0004] Specifically, the solvent equipment explosion-proof and fire extinguishing device comprises a pneumatic air valve installed on an exhaust pipe of a solvent equipment, a nozzle installed inside the solvent equipment and a carbon dioxide fire extinguishing device. The air control end of the pneumatic air valve and the solvent equipment are connected with the output end of the carbon dioxide fire extinguishing device. The signal input end of the carbon dioxide fire extinguishing device is electrically connected with a temperature sensor and a flame detector.

[0005] In some possible implementation manners, the carbon dioxide fire extinguishing device comprises a controller and a carbon dioxide compression tank. The output end of the carbon dioxide compression tank is provided with an electromagnetic valve. The electromagnetic valve, the temperature sensor and the flame detector are electrically connected with the controller.

[0006] In some possible implementation manners, the output end of the electromagnetic valve is connected with a three-way pipe. The first output end of the three-way pipe is connected with the air control end of the pneumatic air valve. The second output end of the three-way pipe is connected with the nozzle.

[0007] In some possible implementation manners, the controller is electrically connected with an alarm.

[0008] In some possible implementation manners, the controller is electrically connected with a camera and a display screen. The camera is installed on the top of the solvent equipment.

[0009] In some possible implementation manners, the solvent device top is embedded with a yttrium oxide transparent ceramic outer shell, the yttrium oxide transparent ceramic outer shell is nested with a yttrium oxide transparent ceramic inner shell, a gap is reserved between the yttrium oxide transparent ceramic outer shell and the yttrium oxide transparent ceramic inner shell, the gap is filled with water, and the yttrium oxide transparent ceramic outer shell and the yttrium oxide transparent ceramic inner shell are fixed through a plurality of connecting ribs, and the camera is mounted inside the yttrium oxide transparent ceramic inner shell.

[0010] In some possible implementation manners, an outer wall of the yttrium oxide transparent ceramic outer shell is coated with a high-temperature-resistant transparent thermal insulation coating.

[0011] In some possible implementation manners, the solvent device is further connected with a backup fire extinguishing port, and the backup fire extinguishing port is mounted with a manual valve.

[0012] In some possible implementation manners, the solvent device is further connected with a pressure relief pipe, the pressure relief pipe is connected with an exhaust system, and the pressure relief pipe is mounted with a pressure relief valve.

[0013] The application has the following beneficial effects: the temperature sensor and the flame detector can be used to simultaneously detect a fire, a fire is determined to occur only when the temperature reaches a preset threshold and the flame is detected, and the two signals of the temperature and the flame are triggered at the same time to release carbon dioxide, thereby improving the anti-interference capability of fire detection and starting the carbon dioxide fire extinguishing device. Moreover, the carbon dioxide is output in two ways, one way is to send the carbon dioxide into the solvent device for fire extinguishing, and the other way is to send the carbon dioxide into the control end of the pneumatic air valve to close the pneumatic air valve. After the pneumatic air valve is closed, the carbon dioxide is sent into the solvent device. Therefore, the linkage of fire extinguishing and exhaust is achieved, the exhaust is closed after the carbon dioxide is released, thereby preventing the loss of carbon dioxide, so that more carbon dioxide remains in the solvent device for fire extinguishing, and the fire extinguishing effect is improved.
