Abstract

The invention relates to a drying oven for spraying, which comprises a drying passage and an exhaust gas incinerator. The drying passage is communicated with the exhaust gas incinerator through an exhaust gas pipeline and an air return pipeline; the wall of the drying passage is provided with an air return outlet, an exhaust gas inlet and an air return inlet; the exhaust gas inlet is communicated with the exhaust gas pipeline; the air return inlet and the air return outlet are communicated with the air return pipeline respectively; the exhaust gas incinerator comprises a heat exchanger which is communicated with the air return pipeline, and a preheater and an incineration chamber which are communicated with the exhaust gas pipeline; and the inlet of the incineration chamber is communicated with the outlet of the preheater, and the outlet of the incineration chamber is communicated with the inlet of the heat exchanger. The drying oven saves a large amount of equipment investment; an exhaust gas heat energy recovery and heat exchange process is introduced based on a hot blast stove with an original drying passage, and the heat energy generated by incinerated exhaust gas is fully utilized, so the heat energy recovery rate is high, energy resources required by the drying oven and the incinerator are greatly saved, and the operating cost is reduced; and the drying oven has the advantages of high exhaust gas treatment efficiency, high incineration temperature, complete exhaust gas decomposition and high purifying rate.

Description

technical field

[0001] The invention relates to a spraying drying device, in particular to a spraying drying furnace integrating waste gas incineration and heat recovery devices. Background technique

[0002] The surface treatment of workpieces mostly adopts spraying technology, such as spray paint and plastic spraying. Most of the spraying agents need to be cured by heating after spraying, and the spraying agents will emit exhaust gas during the heating process. These exhaust gases include gaseous organic compounds. Such as benzene, xylene, etc., have strong toxicity. If they are not treated, they will not only have extremely bad effects on the health of workers, but also pollute the atmosphere. Therefore, waste gas treatment devices must be installed in the establishment of spraying production lines. . Exhaust gas treatment devices and spraying and drying devices currently on the market belong to different industries and are produced by different manufacturers, which resu...
