Research on Environmental Protection Methods for Air Supply and Exhaust in Kitchen Waste Treatment Workshop
In the kitchen waste treatment workshop,the waste treatment process inevitably produces foul smelling gases,if effective measures are not taken for collection and ventilation,it will seriously affect the physical health of personnel in the workshop.In order to save investment,most kitchen waste treatment projects only consider the discharge of odor in the treatment workshop,ignoring the importance of air supply,resulting in poor ventilation,poor gas flow,and a harsh environment in the treatment workshop.This paper compares two typical large-scale domestic kitchen waste treatment projects and analyzes the impact of different air supply and exhaust modes and different layout forms of air supply and exhaust pipes on odor collection and workshop environment.Research has shown that kitchen waste treatment projects need to consider both air supply and exhaust in the workshop,match the air supply and exhaust,and coordinate the layout of air supply and exhaust ducts to ensure negative pressure in the workshop and waste treatment equipment,and that the negative pressure value in the workshop is less than that in the waste treatment equipment,and the gas flow direction is fresh gas outside the workshop → low concentration odor area inside the workshop → high concentration odor area inside the workshop → odor treatment device,ensuring that odor does not diffuse,the environment inside the workshop is good,and there is no odor in the factory area.
