The baking plant purification workshop renovation project uses clean technology to eliminate particulates, harmful air, bacteria and other pollutants in the air in a specific room, and to temperature, humidity, cleanliness, indoor pressure, airflow velocity and airflow distribution in the room. Noise vibration, lighting, and static control are a set of technical work that integrates design and construction within a certain range of requirements. The clean technology used in the renovation of the baking plant purification workshop, namely the pollution control (Contamination Control) technology. Refers to: the object (product, human and animal) in the process of processing, disposal, treatment, protection and experiment, the air in the air (influencing the processing, disposal, treatment, etc. quality, pass rate or The technology of success rate of the substance).

In general, the purification method used in purification engineering is physical purification, which is generally classified into adsorption filtration purification and mechanical filtration purification.

1. Adsorption filtration: Activated carbon is a porous carbonaceous material. It has a highly developed pore structure. The porous structure of activated carbon provides a large amount of surface area and can fully contact with gases (impurities), thus giving activated carbon. The unique adsorption properties make it very easy to absorb and collect impurities. Just like magnetic force, all molecules have mutual attraction.

2, mechanical filtration: HEPA network, HEPA (High Efficiency particulate air filter), Chinese meaning high efficiency air filter, HEPA standard filter, for the efficiency of 0.3 microns is 99.998%, HEPA network is characterized by air can Passed, but the tiny particles could not pass. The HEPA filter consists of a stack of continuous, pre-folded, sub-glass fiber membranes that form a wavy gasket for placement and support of the filter boundary.

Materials used in the renovation of the baking plant purification workshop:

1. The wall and top plate of the purification plant are generally made of 50mm thick sandwich color steel plate, which is characterized by beautiful appearance and strong rigidity. Arc corners, doors, window frames, etc. are generally made of special alumina profiles.

2, the ground can be epoxy self-flowing floor or high-grade wear-resistant plastic floor, anti-static requirements, optional anti-static type.

3. The return air duct is made of hot-dip zinc plate, and the flame-retardant PF foam plastic board with good purification effect is attached.

4, high-efficiency air supply port with stainless steel frame, beautiful and clean, punching stencil with painted aluminum plate, no rust and no dust, should be clean.
