The invention discloses an
energy conservation and emission reduction circulating air
system of a spraying chamber. The
energy conservation and emission reduction circulating air
system comprises a spraying
production line, a circulating
system and a
fresh air system, wherein the spraying
production line comprises a manual pretreatment section, a
machine spraying section, an inspection section anda leveling section; a part of exhaust air of the
machine spraying section, exhaust air of the inspection section, and exhaust air of the leveling section enter an inlet of the circulating system andare exhausted into the
machine spraying section after exhaust air is filtered by the circulating system and temperature and
humidity are adjusted; the other part of exhaust air of the machine sprayingsection is exhausted after follow-up treatment; exhaust air of the manual pretreatment section is directly exhausted to the machine spraying section; and the
fresh air system sucks external
fresh air, and external fresh air is exhausted to the manual pretreatment section, the machine spraying section, the inspection section and the leveling section after external fresh air is filtered and temperature and
humidity are adjusted. According to the
energy conservation and emission reduction circulating air system, the
utilization rate of exhaust air of the spraying chamber can be effectively increased,
energy consumption is greatly reduced, and energy conservation and emission reduction are achieved.
