Straw is the residual part of crops and an important biomass resource. In order to make better use of straw and reduce environmental pollution, straw briquette machine came into being. However, in the process of using straw briquette machine, a lot of dust will be produced, which will pose a threat to human health and the environment. Therefore, dust removal measures are essential. This paper will introduce the dust removal measures of straw briquette machine.

1. Water washing dust removal method. Water washing dust removal method is a common dust removal method. This method uses the washing effect of water to precipitate dust and achieve the purpose of dust removal. In the straw briquette machine, a water washing device can be set up, and when the briquetting machine works, a proper amount of water mist is sprayed to reduce the dust generated to a minimum.

2. Bag dust removal method. Bag dust removal method is an efficient dust removal method. This method uses the bag filter to filter the dust in the air, and traps the dust on the bag to achieve the effect of dust removal. In the straw briquette machine, a bag filter can be set. When the briquetting machine works, the dust generated will be filtered through the bag filter to achieve the purpose of dust removal.

3. Electrostatic precipitation method. Electrostatic dust removal is a dust removal method which uses electrostatic action to adsorb dust on electrodes. In the straw briquette machine, an electrostatic precipitator can be set up. When the briquetting machine works, the generated dust will be adsorbed on the electrode by electrostatic action to achieve the effect of dust removal.

4. Cyclone dust removal method. Cyclone dust removal is a dust removal method that separates dust by rotating fluid. In the straw briquette machine, a cyclone separator can be set up, and when the briquetting machine works, the generated dust is separated by rotating fluid to achieve the effect of dust removal.

5. Activated carbon adsorption method. Activated carbon adsorption is a dust removal method which uses activated carbon to adsorb harmful gases and particles in the air. In the straw briquette machine, an activated carbon adsorption device can be set up. When the briquetting machine works, harmful gases and particles in the air can be adsorbed by activated carbon to achieve the effect of dust removal.

To sum up, the dust removal measures of straw briquette machine include washing dust removal, bag dust removal, electrostatic dust removal, cyclone dust removal and activated carbon adsorption. When using the straw briquette machine, the appropriate dust removal method should be selected according to the specific situation to achieve the best dust removal effect.
