[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] like Figure 1 As shown, existing technologies for explosive dust removal generally employ dry or wet dust collection processes. This invention utilizes a wet dust collection method, specifically including a water storage tank 1. A wet dust collection tower 2 is installed within the water storage tank 1. A dust conveying pipe 10 is connected to the top of the wet dust collection tower 2, and a dust collector 11 is connected to the other end of the dust conveying pipe 10. The dust collector 11 sends external dust into the interior of the wet dust collection tower 2. This product is mainly used for the dust removal and recovery of aluminum powder. A water supply pipe 4 is connected to the side of the wet dust collection tower 2, and a water pump 3 is connected to the end of the water supply pipe 4. The water pump 3 is placed inside the water storage tank 1 and pumps the water from the water storage tank 1 into the interior of the wet dust collection tower 2 to mix with the dust. A water replenishment pipe 8 is introduced into the water storage tank 1 to replenish water. The bottom of the wet dust collection tower 2 is a sludge outlet, which is submerged in the water of the water storage tank 1. After sludge sedimentation, it can be discharged from the water storage tank 1.

[0015] Based on the existing foundation, the following improvements are made:

[0016] A flow detection sensor 5 is installed on the water supply pipe 4 to detect the water flow rate in the water supply pipe 4 and monitor whether the water supply to the wet dust collector 2 is sufficient. A water supply pressure sensor 9 is installed on the water supply pipe 8 to monitor the water pressure in the water supply pipe 8 and determine whether the water supply speed of the water storage tank 1 meets the requirements. A liquid level sensor 12 and a temperature sensor 13 are installed in the water storage tank 1. The liquid level sensor 12 is used to monitor the water level in the water storage tank 1 to ensure that the water volume in the water storage tank 1 is sufficient. Since the entire device is located outdoors, the temperature sensor 13 is used to monitor the temperature to prevent the water in the water storage tank 1 from freezing and failing to perform the dust removal function. The data collected by the flow detection sensor 5, the water supply pressure sensor 9, the liquid level sensor 12, and the temperature sensor 13 are transmitted to the programmable logic controller (PLC). The programmable logic controller (PLC) can integrate the data transmitted from various sensors. The programmable logic controller (PLC) is equipped with a 4G communication module, which can transmit the corresponding data to a remote location to realize remote operation and maintenance and early warning.

[0017] In enterprises dealing with explosive dust, the presence of aluminum powder and moisture in the environment can lead to the generation of hydrogen gas under certain conditions. If this hydrogen gas accumulates in a confined space and mixes with air to reach a concentration within a certain range (the explosive limits of hydrogen are 4.0% - 75.6% by volume), it will ignite upon contact with a source of ignition. Therefore, in such enterprises, it is necessary to monitor the hydrogen concentration in the environment and implement effective ventilation and other safety measures to prevent the accumulation of hydrogen gas and the resulting hazards.

[0018] A hydrogen concentration detection sensor 14 is installed near the exhaust port of the wet dust collector 2. The data collected by the hydrogen concentration detection sensor 14 is transmitted to the programmable logic controller (PLC). This device is mainly used for the dust removal and recycling of aluminum powder, so it is very necessary to install the hydrogen concentration detection sensor 14.

[0019] A connecting pipe 6 is connected to the side of the wet dust collector 2, and an explosion-proof valve 7 is installed on the connecting pipe 6. An explosion relief port 15 is provided on the top side of the wet dust collector 2.

[0020] The function of the explosion vent 15 is primarily to release the high pressure generated by an explosion in a timely manner. When an explosion occurs in an explosive dust environment, it generates enormous pressure instantaneously. If this pressure cannot be released in time, it may cause severe damage to equipment, buildings, etc., due to excessive pressure. The explosion vent 15 opens when the pressure reaches a certain level, dispersing the explosion energy to a safe area, preventing the explosion pressure from causing devastating damage to surrounding facilities, reducing the scope and severity of the explosion hazard, and ensuring the safety of personnel and the integrity of equipment.

[0021] The function of an explosion relief valve: In the event of an explosion, the explosion relief valve can respond quickly to block the propagation of the explosion flame and shock wave. It can quickly close in the early stages of an explosion, preventing the explosion from spreading between different equipment or areas and avoiding a chain reaction of explosions. For example, in the piping system of enterprises dealing with explosive dust, the explosion relief valve can effectively limit the explosion to a localized area, reduce the impact of the explosion on the entire production system, and buy time for the enterprise to control the development of the accident and reduce losses.

[0022] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
