1. Introduction: During the operation of factories in industrial zones, the new solid waste to liquid and gas, and dust is inevitable. Therefore the process of pollution is extremely important to protect the environment, protect the health of the community. Face reality that the company has focused on offering solutions to environmental process for this region, to contribute to the environmental protection of the country and create a good environment for producers business. 2. Principle activities: At the source of dust arise, when reading in the operation of the factory is collected by the system capture the smoke and smoke and wind with a large enough pressure to ensure that the resources arising to be collected completely. Depending on the case that we have made travel and local travel directly in the area of dust and pollution. Then the dust, gas is transported to processing equipment. Here are the air draft is defined components to select the equipment to handle most relevant such as traffic, heat, dust components, chemical components of the gas. .. It also decided to select the level to handle most appropriate to achieve the two criteria of economy and technology. Equipment in this process if the process is dust and dust will be out in a separate waste line outside, as if in the air will be absorbed and the absorbed substances are transported out of, or calcify secondary to the substance is not harmful to the environment. Standard products are designed and manufactured in accordance with the standards of Vietnamese concentration of gas outside the external environment. The criteria for creating and processing on the air pipe, the noisy, filter equipment. Absolute guarantee of the optimal design, selection of equipment with appropriate technology and production lines to ensure durability of materials and equipment, flexibility in control and saving energy in the operation. 3. Application Products are for the following industries: a. Industrial cement b. Embryo industrial steel, rolled steel c. Industry wood processing industry d. Industrial exploitation, the exploitation of stone e. Industrial paint f. Industrial production of food animals ... 4. Special features: System designed to optimize the technical standards as well as the conditions of operation for easy and convenient. In the case where the system can be designed save energy and make use of excess heat from the sub-factory of production.
