Casting waste gas treatment equipment

Abstract

The invention discloses casting waste gas treatment equipment, which comprises an outer shell, an inner shell, a water-gas separation tank, a grit chamber, a spray head and a vibration mechanism, wherein the upper end of the inner shell is fixedly connected with the top of the outer shell; the lower end of the inner shell penetrates through the bottom of the outer shell and extends out of the outer shell; the outer shell and the inner shell form a containing cavity together; and metal wire balls are filled in the containing cavity; the water-gas separation tank is arranged below the inner shell, the top of the water-gas separation tank is communicated with the bottom of the inner shell, and the bottom of the water-gas separation tank is communicated with the water inlet end of the grit chamber. A spraying device is arranged in primary dust removal equipment, so that the occupied area is reduced, the contact efficiency of an airflow and a vertically moving water flow is greatly improved, the spraying purification effect is improved, the equipment operation noise is low, and the secondary environmental pollution is greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of waste gas treatment equipment, in particular to casting waste gas treatment equipment. Background technique [0002] A large amount 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 and phenol are volatilized and cracked in the process of core making and high-temperature pouring. 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. Purification of foundry exhaust gas needs to be carried out in several steps. Most of the existing related purification equipment has simple structure and single function, and has disadvantages such as lo...

Problems solved by technology

[0002] A large amount 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 and phenol are volatilized and cracked in the process of core making and high-temperature pouring. 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 relevant national emission standards are met.

Casting exhaust gas purification needs to be carried out in several steps. Most of the existing related purification equipment has simple structure and single function, and has disadvantages such as low purification efficiency, high operating noise, and large floor space.
