Single-color-group RST circulating thickening and emission reduction heat treatment equipment and system

The invention provides monochromatic group RST circulating thickening and emission reduction heat treatment equipment and system, relates to the field of organic waste gas treatment, and solves the problem that in the prior art, thickening and emission reduction cannot be truly achieved. The monochromatic group RST circulating thickening and emission reduction heat treatment equipment comprises a first fan, a color group heat oven, a VOCs concentration sensor and a second valve which are sequentially connected through a pipeline; the air inlet end of the first valve communicates with the external environment, the air outlet end of the first valve is connected into a pipeline from the air outlet end of the second valve to the air inlet of the first fan, and the air inlet of the second fan is connected into a pipeline from the air outlet of the color cell heat drying oven to the air inlet end of the second valve through a pipeline. An air inlet end and an air outlet end of the third valve are respectively conne
