Description
Technical field
The present invention relates to a kind of exhaust treatment system, specifically relate to a kind of circulation enrichment exhaust treatment system.
Background technology
Coating machine is used for coating to be produced, and the base material of rolling is coated with glue, coating or the printing ink etc. of last layer specific function, and dries the back rolling.It adopts special-purpose high-speed coating head, can effectively reduce the generation of bubble, and the unwinding and rewinding of coating machine are all disposed at full speed and met film mechanism automatically, and tension closed loop is controlled automatically.Can produce volatile organic waste gas such as methyl alcohol in the coating dry run, directly discharging pollutes atmospheric environment.The method of handling this volatile organic waste gas at present has several methods such as catalytic oxidation combustion, absorption method, absorption method, according to volatile organic waste gas concentration difference, selects rational processing mode most important.General catalytic oxidation combustion one-time investment is higher, absorption method, absorption method operating cost height, if this part organic exhaust gas is directly burnt, calorific value is far from reaching the direct combustion standard of organic exhaust gas, needs to increase fuel cost.Therefore, the research and development one cover circulation enrichment exhaust treatment system that the organic exhaust gas that discharges in the coating machine is recycling is the technical problem that those skilled in the art are badly in need of solving, and the present invention produces thus.
Summary of the invention
For solving the problems of the technologies described above, the purpose of this invention is to provide a kind of circulation enrichment exhaust treatment system, the organic exhaust gas that coating machine produces part circulation after air-introduced machine is extracted out is heated as the oven dry medium, another part directly enters the burner hearth burning, thereby reduced the consumption of fuel, also reached the purpose of environment protection emission simultaneously.
For achieving the above object, the present invention is achieved by the following technical solutions:
A kind of circulation enrichment exhaust treatment system, comprise coating machine, described coating machine is connected with waste gas circulation combustion heat wind furnace and air-introduced machine, described waste gas circulation combustion heat wind furnace is connected with air blast and circulating fan, described circulating fan is connected with air valve, described air blast is connected with first valve, described air-introduced machine is connected with second valve, described first valve is connected with air-introduced machine, described second valve, one end is connected between air valve and the circulating fan, the second valve other end is connected between first valve and the air-introduced machine, is connected with the oxygenating valve between described first valve and the air blast.
