[0002] Large-scale coating companies represented by shipbuilding companies need to maintain a certain temperature in the coating workshop during winter coating operations to speed up the curing of the paint film. In order to shorten the paint curing time and speed up the turnover of workpieces, the air in the coating workshop needs to be heated. The traditional heating method is to use electric / gas / oil heating and air supply units to heat the indoor air.
[0003] VOCs treatment equipment can recover heat to a certain extent, but some high-temperature waste gas that can be recovered will still be directly discharged into the atmosphere. For example, this part of high-temperature waste gas is generally below 200°C, which is low-temperature waste heat. If this part of low-temperature waste heat is used to heat the workshop to accelerate paint curing, it can partially or even completely replace the electric heater heating or gas / oil heating of the air supply system, saving equipment investment and operating costs for heating and air supply.
[0004] Although the heating and air supply system based on the low-temperature waste heat of VOCs treatment equipment has the advantages of saving equipment investment and reducing operating costs, it is restricted by the instability of the low-temperature waste heat of the VOCs treatment equipment. The heating and air supply unit often operates at a higher heating power, resulting in increased energy consumption for shipping companies. There is an urgent need for a real-time heating and air supply control system based on the utilization of low-temperature waste heat from VOCs treatment equipment to improve the energy efficiency of the heating and air supply system.
