Column-distributed ventilation heating system and method for high-pollution oil mist emission plant

Abstract

The invention discloses a column-distributed ventilation heating system and method for a high-pollution oil mist emission plant. The method comprises the steps that clean air lower than the room temperature is fed through air supply outlets formed in the periphery of a column structure of the high-pollution oil mist emission plant and below the height of a breathing area and passes through a working area in the high-pollution oil mist emission plant, personnel, process equipment and the like in the working area transfer heat to the clean air, the clean air carries oil mist generated in the working area to rise under the driving of thermal buoyancy and then is discharged from an exhaust outlet formed in the top of the high-pollution oil mist emission plant, and a ceiling infrared radiationheater arranged above a production line of the working area is started in an auxiliary mode when the fed air cannot meet the load requirement. Therefore, the ventilation efficiency can be effectivelyimproved, the energy consumption can be reduced, the oil mist concentration of the working area can be reduced, and the quality of the working environment can be improved.

Description

technical field [0001] The invention relates to the field of heating, ventilating and air conditioning, and relates to a column-along distributed ventilation and heating scheme suitable for high-pollution oil mist emission factory buildings, and in particular to a column-along distributed ventilation and heating system and method for high-pollution oil mist emission factory buildings. Background technique [0002] In recent years, with the urgent demand for green buildings, building indoor air quality and energy saving has become a research hotspot, but most of the related research focuses on civil buildings while industrial buildings are neglected. With the development of industrialization and the gradual emphasis on the working environment of workers, it is particularly important to propose a ventilation and heating scheme suitable for high-pollution industrial plants.

AI Technical Summary

Problems solved by technology

[0003] After investigation, the current situation of the domestic factory environment needs to be improved. Taking the machining workshop as an example, its processes usually include turning, milling, planing and grinding. The temperature requirements of tall factory buildings are usually regulated by high-volume mixed ventilation, and the messy airflow organization often leads to oil mist concentration limits that usually exceed worker health limits.

Researches at home and abroad have pointed out that the traditional displacement ventilation suitable for providing a cleaner space is usually installed near the enclosure structure. The area is also limited to the load that can be carried
