Example Embodiment

[0032] The present invention will be further described in detail below through specific implementation examples in conjunction with the accompanying drawings.

[0033] A method for treating casting waste gas includes the following steps:

[0034] In the first step, the exhaust gas generated on the casting production line is collected through the suction collecting cover.

[0035] Further, in this embodiment, the waste gas includes waste gas generated by the mechanized pouring production line on the foundry production line, the ground manual pouring site, and the smelting furnace. The waste gas on the mechanized pouring production line is collected by a flip-type suction collection cover, and the ground manual pouring production site The exhaust gas generated is collected by a long-strip mobile suction collecting hood, and the exhaust gas produced in the melting furnace is collected by a rotating suction collecting hood.

[0036] Through comprehensive exhaust gas treatment in multiple ...

Abstract

The invention relates to the technical field of casting waste gas treatment, and particularly provides a casting waste gas treatment method and device. The method comprises the steps that waste gas generated on a casting production line is collected through air suction collection covers; collected waste gas is gathered and conveyed to a low-temperature plasma and compound photocatalysis industrial waste gas purifier through a pipeline to be treated; the treated gas is exhausted into the atmosphere. The casting waste gas treatment device comprises the air suction collection covers, the waste gas collection pipeline, the low-temperature plasma and compound photocatalysis industrial waste gas purifier and a main fan. The multiple air suction collection covers are arranged on the casting production line according to the number of waste gas sources in casting production and communicated with the gas inlet end of the waste gas collection pipeline. The gas outlet end of the waste gas collection pipeline is communicated with a gas inlet of the purifier. A gas outlet of the purifier is communicated with the atmosphere through an exhausting device. The purpose that smoke and organic waste gas are collected and treated in the casting process is achieved, and the problem that an existing treatment technology of existing waste gas casting treatment through a wet method is complex is solved.

Description

technical field [0001] The invention relates to the technical field of casting waste gas treatment, in particular to a casting waste gas treatment method and device. Background technique [0002] As we all know, a lot of smoke, dust and heat will be generated in the casting production process, especially in the equipment manufacturing industry, the relatively common resin-coated sand is currently used, and a large amount of formaldehyde is volatilized and cracked in the process of core making and high-temperature pouring , phenols, amines and other organic compounds with peculiar smell. These toxic and harmful gases not only deteriorate the production environment, but also cause serious pollution to the atmosphere around the factory area. Effective treatment must be carried out to ensure that the relevant national emission standards are met. Existing foundry waste gas treatment usually adopts wet treatment. However, wet treatment of foundry waste gas often brings additional...
