[0027] Through the above structure, the dust hood 1 is installed on the top or upper side of the straw feed production equipment, and the high-speed fan 2 is started. The dust-containing gas inside the straw feed production equipment is sent to the air supply pipe 3 through the high-speed fan 2, and is sent to the inside of the installation frame 4 through the air supply pipe 3. The gas is sent to the inside of the multiple groups of filter bags 8 through the multiple groups of air guide buckets 18. The gas is filtered by the filter bags 8. The gas reflux inside the filter bags 8 is reduced by the bucket-shaped air guide bags 11, driving the dust to float back to the inside of the installation frame 4. The gas filtered by the filter bags 8 is sent to the bottom of the treatment water tank 5. Some fine dust is dissolved in the water at the bottom of the treatment water tank 5. The fine dust is filtered out through the dust filter exhaust port 12, and the clean gas is discharged from the treatment water tank 5. The specific structure is as follows:

[0028] Combined with Figure 4 and attached Figure 5 As shown, a plurality of groups of scattered air ducts 6 are installed at the lower side of the air supply duct 3, the lower ends of the scattered air ducts 6 pass through the interior of the installation frame 4, a supporting keel 10 is installed at the lower side of the connecting pipe 9, the outer side of the filter bag 8 is bonded to the supporting keel 10, and the lower side of the filter bag 8 is placed in the middle of the treated water tank 5.

[0029] Through the above structure, the gas can be evenly delivered to the inside of the installation frame 4 through multiple groups of air distribution pipes 6, so that multiple groups of filter bags 8 can perform the same filtering work. The filter bags 8 are positioned and supported by the supporting keels 10 to prevent the filter bags 8 from shaking and causing damage after being filled with gas. The lower side of the filter bags 8 is located in the middle of the treatment water tank 5, so that the filter bags 8 will not come into contact with the water at the bottom of the treatment water tank 5.

[0030] Combined with Figure 1 and attached Figure 3 As shown, connecting frames 17 are respectively installed on the two opposite side walls of the installation frame 4, a water pipe 13 is installed through the lower part of one side wall of the treatment water tank 5, a connecting frame 14 is installed on the lower side of the installation frame 4, and a connecting frame 2 15 is installed on the upper side of the treatment water tank 5. The connecting frame 2 15 is sleeved on the outside of the connecting frame 1 14 and is equipped with multiple sets of bolts 16 for matching connection.

[0031] Through the above structure, the installation frame 4 is fixedly installed through the connecting frame 17, and can be installed on the equipment bracket or the top of the workshop. The water inlet and outlet of the treatment water tank 5 can be controlled through the water pipe 13. The water pipe 13 is provided with a control valve for closing. The connecting frame 2 15 is sleeved on the outside of the connecting frame 1 14 and connected by multiple groups of bolts 16, so that the treatment water tank 5 can be disassembled on the lower side of the installation frame 4, which is convenient for the maintenance of the filter bag 8.
