Problems solved by technology

Most of the concentration increase and emission reduction systems on the market use time relays to control the emission of VOCs organic waste gas from the thermal ovens of printing machines. The concentration of VOCs organic waste gas emissions from the heat ovens of each color group is different, and it is impossible to truly achieve concentration increase and emission reduction, resulting in a large amount of waste gas emissions. Larger, the load of exhaust gas treatment equipment is increased, and the operating cost is increased

Abstract

The invention provides RST circulation thickening and emission reduction heat treatment equipment and system, relates to the technical field of organic waste gas treatment, and solves the problem that thickening and emission reduction cannot be truly achieved in the prior art. The RST circulation thickening and emission reduction heat treatment equipment comprises a first fan, a first color cell heat oven, a second fan, a second color cell heat oven and a second valve which are sequentially connected through pipelines; the air inlet end of the first valve communicates with the external environment, and 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. An air inlet of the third fan is connected into a pipeline from an air outlet of the second color cell heat oven to the air inlet end of the second valve through a pipeline; the air inlet end and the air outlet end of the third valve are respectively connected with an air outlet of the third fan and waste gas treatment equipment through pipelines. Compared with the prior art, thickening and emission reduction of VOCs organic waste gas of the hot drying oven of the printing machine can be truly achieved, the efficiency of waste gas treatment equipment is better improved, and energy conservation and consumption reduction are achieved.

Description

technical field [0001] The invention relates to the technical field of organic waste gas treatment, in particular to an RST cycle enrichment and emission reduction heat treatment equipment and system. Background technique [0002] For the VOCs organic waste gas generated in the printing production process, the most common method is to use the regenerative combustion method to decompose the organic waste gas into carbon dioxide and water for emission. With this method, when the concentration of organic waste gas reaches a certain level, spontaneous combustion can be maintained without additional fuel for heating, which greatly saves the fuel consumed by the equipment and reduces the operating cost of the enterprise. In printing production, the number of colors used in different product pattern designs is different, and the size of the layout is different. The concentration of VOCs organic waste gas produced by each color group is also different. The VOCs organic waste gas emi...
