[0018] The utility model is further described in detail below in conjunction with the accompanying drawings and specific embodiments. According to the following description, the advantages and features of the utility model will become clearer. It should be noted that the drawings are all in a very simplified form and are not in precise proportions, and are only used to conveniently and clearly assist in explaining the purpose of the embodiments of the utility model.

[0019] like Figure 1-4As shown, the embodiment of the utility model provides a spray dust reduction and deodorization device, including a frame 1, and the bottom of the frame 1 also includes universal wheels installed for easy movement; a water tank 2, a doser 3, a filter and a high-pressure pump 4 are installed on the frame 1 respectively; the external water supply pipeline is connected with the filter, the doser 3 and the water tank 2 in sequence, the input end of the high-pressure pump 4 is connected with the bottom of the water tank 2, and the output end is connected with the spray pipe network 5, and the spray pipe network 5 is arranged on the top of the drying workshop 6; wherein the agent injected into the doser 3 is a microbial agent, and the microbial agent is EM bacterial liquid. The above-mentioned spray pipe network 5 is arranged on the top of the drying workshop 6, and its spraying area completely covers the drying material stacking and aging area. First, water is transported through the external water supply pipeline, and after three-stage filtration through the filter, it is mixed with the EM bacterial liquid in the doser 3 and enters the water tank 2 until the liquid level height in the water tank 2 meets the full state. When spray deodorization is performed, by controlling the operation of the high-pressure pump 4, the tap water added with EM bacterial liquid in the water tank 2 is pumped to the spray pipe network 5 to perform high-pressure spray dust removal on the stacking and aging area. At the same time, deodorization is performed by adding microorganisms, namely, EM bacterial liquid degradation, so as to improve the working environment in the workshop.

[0020] The filter is a 20-inch three-stage pre-tap water filter to filter impurities in the tap water transported by the water supply pipeline to avoid clogging the atomizing spray nozzles on the spray pipe network 5 system.

[0021] The doser 3 is a hydraulically driven constant ratio diluter, which can improve the mixing uniformity between the drug solution and the tap water.

[0022] The high-pressure pump 4 also includes a pressure gauge 41 and a pressure relief valve installed, which can display the pressure on the high-pressure pump 4 in real time and perform safe pressure relief. The output end of the high-pressure pump 4 also includes a pressure regulating valve installed, which can regulate the water pressure at the output end of the high-pressure pump 4.

[0023] The output end of the high-pressure pump 4 also includes two connected bypass pipes 42, on which solenoid valves 43 are respectively installed. The bypass pipes 42 are connected to the spray network 5. The two bypass pipes 42 are used to pump water to the spray network 5. Compared with a single bypass pipe, the time for the bypass pipe 42 to fill the spray network 5 can be shortened.

[0024] The water tank 2 also includes a liquid level sensor that can display the liquid level in the water tank 2 in real time to facilitate water filling and drug addition.

[0025] It also includes a PLC electric control box 7, which is provided with an HMI human-machine interface touch screen, a power indicator light, an operation indicator light, an alarm indicator light, a manual / automatic switch button and an emergency stop button. The PLC electric control box 7 is electrically connected to the high-pressure pump 4, the solenoid valve 43 and the liquid level sensor respectively.

[0026] It also includes the following workflow:

[0027] The utility model intends to use high-pressure spray dust removal technology to control dust, and equip the spray device with microbial EM bacteria dosing equipment to improve the odor in the workshop. The metabolic action of microorganisms is used to convert odorous substances into CO 2 , H 2 O, SO 4 2- and NO 3- The production of bacteria is beneficial to subsequent purification, combining the advantages of mass transfer and biodegradation. At the same time, the lactic acid and alkaloids metabolized by microorganisms can effectively react with hydrogen sulfide and ammonia in the odor to form organic salts.
