An internal circulation spray booth

Abstract

The invention discloses an internal circulation type spraying room. The internal circulation type spraying room comprises a paint spraying room, a paint mist filtering system, an air conditioning system and a control system, wherein the paint mist filtering system is connected with the paint spraying room and used for filtering paint mists and supplementing fresh air, the air conditioning system is connected with the filtering system and used for exhausting waste gas and supplying air to the paint spraying room according to a certain proportion of fresh air and previous air, and the control system is connected with the paint spraying room, the paint mist filtering system and the air conditioning system and used for adjusting the proportion of fresh air and previous air and supplementing fresh air according to the concentration of the paint mists in the paint spraying room. According to the invention, gas with a certain enthalpy value can be recycled, and therefore the production cost can be saved.

Description

technical field [0001] The invention relates to a spray processing equipment, in particular to an internal circulation spray booth. Background technique [0002] The existing water curtain spraying room has a certain distance from the spray paint mist to the entrance of the treatment area, because it needs a considerable amount of air to inhale all the air containing the spray paint mist, which requires a lot of energy consumption ; The water baffle in the paint mist treatment area can only block the water into the water tank, but cannot further absorb the remaining paint mist, resulting in unsatisfactory paint mist treatment in the paint mist treatment area, and part of the paint mist overflows from the air outlet. In the air supply system of the spray booth, the air conditioning system with all fresh air is generally used, which is directly sent to the exhaust, and the constant temperature and wet air can only be used once, and the energy consumption is high; and because t...

[0002] The existing water curtain spraying room has a certain distance from the spray paint mist to the entrance of the treatment area, because it needs a considerable amount of air to inhale all the air containing the spray paint mist, which requires a lot of energy consumption ; The water baffle in the paint mist treatment area can only block the water into the water tank, but cannot further absorb the remaining paint mist, resulting in unsatisfactory paint mist treatment in the paint mist treatment area, and part of the paint mist overflows from the air outlet

In the air supply system of the spray booth, the air conditioning system with all fresh air is generally used, which is directly sent to the exhaust, and the constant temperature and wet air can only be used once, and the energy consumption is high; and because the large air volume dilutes the concentration of the released gas, it also causes Exhaust gas treatment is very difficult. The current activated carbon method, catalytic combustion method, and RTO combustion method (regenerative rotary incineration) all have the problem of high air volume treatment cost and cannot be promoted.
