The invention discloses an industrial boiler exhaust gas treatment device, which comprises a base. The top of the base is fixedly connected with a boiler and a dust removal box in sequence from left to right. The bottom of the left side of the dust removal box is fixedly connected with a second support plate. The top of the plate is fixedly connected with a second exhaust fan. The present invention uses a base, a dust discharge pipe, a dust removal box, a first support plate, a first exhaust fan, an air inlet pipe, an exhaust pipe, a shell, an air outlet pipe, a dust outlet pipe, a second exhaust fan, a second support plate, an air inlet The combined use of dust pipe, boiler, activated carbon filter, dust removal net, suction hood, fixed seat and ultraviolet germicidal lamp solves the problem that the existing industrial furnace exhaust gas treatment device has poor exhaust gas treatment effect. The industrial furnace exhaust gas treatment The device has the advantage of better treatment effect on exhaust gas, reduces the pollution of the exhaust gas to the environment, reduces the harm of the exhaust gas to the user's body, and improves the practicability of the industrial boiler.
