Tail gas treatment device of enamelling machine

Abstract

The invention discloses a tail gas treatment device, and particularly relates to a tail gas treatment device of an enamelling machine. A tail gas collection pipeline is provided with branch collectionpipes; the branch collection pipes are correspondingly connected with enamelling machine waste discharge pipes; one side and the other side of an induced draft fan are connected with the tail gas collection pipeline and a fresh air fan correspondingly; the induced draft fan is connected with a catalytic head in a combustion oxidation chamber; a heater is arranged under the catalytic head; the right side of the combustion oxidation chamber is connected with a heat exchanger; a heat exchange pipeline is arranged in the heat exchanger and connected with a cooling tower; an outlet of the heat exchanger is connected with an inlet of a photolysis tower; an outlet of the photolysis tower is connected with an inlet of an activated carbon adsorption tower; and an outlet of the activated carbon adsorption tower is connected with a chimney. The tail gas treatment device of the enamelling machine has the advantages of being reasonable in structural design, low in cost, compact in structure, smallin occupied space, capable of saving energy, high in waste gas treatment efficiency, good in purification effect and the like, and is suitable for application and popularization.

Description

technical field [0001] The invention relates to the field of tail gas treatment devices, in particular to a tail gas treatment device of an enamelling machine. Background technique [0002] The enamelling machine is used to produce enameled wire. It is to coat insulating varnish on the surface of the conductor (copper or aluminum, etc.) and form an enameled wire after drying. The enamelling machine is a kind of equipment with high pollution, high energy consumption and high material consumption, because enameled wire is in During the roasting process, a large amount of benzene, toluene, xylene, phenols and cyclohexane are produced, which are sent to the catalytic chamber by the circulating fan, burned under the action of the catalyst, and the heat generated is supplemented to the oven, but some exhaust gas is still discharged directly , or the exhaust fan is turned too large in the production process, or the catalyst is invalid or the gas temperature before the catalysis is ...

[0002] The enamelling machine is used to produce enameled wire. It is to coat insulating varnish on the surface of the conductor (copper or aluminum, etc.) and form an enameled wire after drying. The enamelling machine is a kind of equipment with high pollution, high energy consumption and high material consumption, because enameled wire is in During the roasting process, a large amount of benzene, toluene, xylene, phenols and cyclohexane are produced, which are sent to the catalytic chamber by the circulating fan, burned under the action of the catalyst, and the heat generated is supplemented to the oven, but some exhaust gas is still discharged directly , or the exhaust fan is turned too large in the production process, or the catalyst is invalid or the gas temperature before the catalysis is too low or other reasons make the catalysis incomplete, resulting in benzene, toluene, xylene, phenols and cyclohexane in the exhaust. into the atmosphere

[0003] On the surface, the method of discharging after secondary catalytic combustion has realized the environmental protection of exhaust gas, and the content of harmful substances discharged by this method has also reached the environmental protection emission standard, but there are still some problems in this method. The odor cannot be eliminated; second, if the catalytic combustion is not sufficient, the exhaust gas emission cannot be guaranteed to meet the standard, and the problem becomes more obvious the longer the enamelling machine is used
