Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings.

[0022] like Figure 1 , Figure 2 As shown in the figure, this application embodiment proposes an explosion-proof safety device for intelligent fluid processing, including a detection module and a collection module 3. The collection module 3 includes a device housing 301, which has an interconnected inner cavity and a negative pressure suction port 302. The inner cavity is equipped with a dust consolidation device and a fan 308. The dust consolidation device has an air inlet 317 and an air outlet 307. The air inlet 317 is connected to the negative pressure suction port 302, and the air outlet 307 is connected to the suction end of the fan 308. The air outlet of the fan 308 is connected to a gas storage structure. The detection module includes a sensor structure 1 and a controller 2 that are electrically connected to each other. The controller 2 is electrically connected to the fan 308. The sensor structure 1 is used to detect the dust concentration and gas composition at a specified location. The controller 1 is an existing control software that is compatible with the device and controls the operation of the collection module 3 after receiving signals. Moreover, the overall electronic circuit and switches are explosion-proof wires and explosion-proof switches.

[0023] First, it should be stated that after the sensor structure 1 detects an excessive leak of toxic gas or dust, it transmits the data to the controller 2. The controller 2 then controls the fan 308 to start, drawing the toxic gas, dust, or their mixture into the equipment housing 301. At the same time, it controls the dust agglomeration device to agglomerate and collect the dust, while simultaneously drawing the toxic gas into the gas storage structure. This enables a rapid response and minimizes the potential for leaks of toxic gas, dust, or their mixture, effectively improving the efficiency of eliminating potential leaks of toxic gas or dust in chemical production activities.

[0024] The aforementioned dust consolidation device includes a housing, with the air inlet 317 and the air outlet 307 respectively located on opposite side walls of the housing. A collection box 310 is connected to the lower end of the housing, and a consolidation chamber 304 is provided inside the housing. Both the air inlet 317 and the air outlet 307 are connected to the consolidation chamber 304. An inclined plate structure is provided inside the consolidation chamber 304, with the inclined surface of the inclined plate structure facing the side of the air inlet 317. It also includes a spray structure, with the spray direction of the spray structure facing the inclined surface of the inclined plate structure. In other words, the fan 308 is used to draw leaked toxic gases and dust into the consolidation chamber 304. Under the action of the inclined plate and the spray structure, the drawn-in dust is consolidated on the inclined plate. If toxic gases are present, the toxic gases are introduced into the gas storage structure from the air outlet 307, realizing a dual collection process of dust and toxic gases.

[0025] It also includes a connecting pipe 303. The negative pressure suction ports 302 are evenly arranged in a plurality of the above-mentioned equipment housing 301, and the plurality of negative pressure suction ports 302 are all sealed and connected to the connecting pipe 303. The connecting pipe 303 is connected to the air inlet 317. The arrangement of the connecting pipe 303 ensures sufficient air tightness; and the plurality of negative pressure suction ports 302 can ensure the efficiency of extracting leaked materials.

[0026] The aforementioned gas storage structure includes a compressed gas tank 309, which is electrically connected to the controller 2. Toxic gas enters the compressed gas tank directly through the outlet 307 for compression and storage, and the pressure inside the compressed gas tank does not exceed 0.1 MPa.

[0027] The aforementioned inclined plate structure includes a motor 306 disposed in the aforementioned housing, which is electrically connected to the aforementioned controller 2. A rotating plate 305 is connected to the output end of the motor 306. The rotating plate 305 is inclined with its inclined surface facing the air inlet 317. The rotating plate 305 is driven by the motor 306 to rotate circumferentially within its plane. During operation, the motor 306 controls the rotation of the rotating plate 305, and the spray angle of the spray structure is perpendicular to the rotating plate. The sprayed substance can be a coagulant or water. Under the rotational action and the spraying effect of the spray structure, dust can quickly agglomerate into large spherical particles that roll off the rotating plate for easy collection. In one embodiment, the inclination angle of the rotating plate 305 is 45°, resulting in optimal collection. The above-mentioned spray structure includes a water tank 316, and a water pump 315 is connected to the water tank 316. The outlet of the water pump 315 is provided with a nozzle 314, and the water pump 315 is automatically controlled to start and stop by the controller 2 to realize automatic control.

[0028] Furthermore, multiple nozzles 314 are provided, and the spray area of ​​multiple nozzles 314 completely covers the inclined surface of the inclined plate. Each nozzle 314 is equipped with an electric regulating valve, which is used to open and close the nozzle 314 and regulate the water spray volume. The electric regulating valve is electrically connected to the controller 2. The arrangement of multiple nozzles 314 can ensure full coverage of the inclined plate surface and improve the efficiency of dust agglomeration.

[0029] Furthermore, to facilitate the collection of solidified dust spherical particles, a collection port 311 is provided at the connection point between the collection box 310 and the outer shell. The collection port 311 is funnel-shaped and located below the inclined plate structure. An automatic valve 312 is installed in the collection port 311 and is electrically connected to the controller 2. After the dust spherical particles are formed, they roll from the turntable into the funnel-shaped collection port 311 and then fall into the collection box 310. To ensure airtightness and prevent toxic gases from entering the collection box 310 during extraction, the controller 2 activates the automatic valve 312 even without extraction, ensuring that the dust particles accumulated in the collection port 311 fall into the collection box 310. An automatic discharge port 313 is provided at the lower end of the collection box 310 and is electrically connected to the controller 2. The controller 2 controls the automatic opening and closing of the automatic discharge port 313 to achieve the cleaning of solidified dust.
