Environment-friendly cupola

Abstract

The invention relates to an environment-friendly cupola. The cupola comprises a cupola body box and a waste gas treatment device connected with the cupola body box, wherein the cupola body comprises a flue gas chamber; the lateral surface of the flue gas chamber is connected with the waste gas treatment device via a first flue gas pipe; the waste gas treatment device comprises a large cooler, a small cooler, a third flue gas pipe, a bag dust collector, a fourth flue gas pipe, a fifth flue gas pipe, a draught fan, a spray desulphurization device and a chimney; the upper end and lower end of the large cooler are respectively connected with the small cooler and the first flue gas pipe; the lower part of the smaller cooler is connected with the inlet of the bag dust collector by the third flue gas pipe; the bag dust collector is connected with the air inlet of the draught fan by the fourth flue gas pipe; the air outlet of the draught fan is connected with the upper part of the spray desulphurization device by the fifth flue gas pipe; and the lower part of the spray desulphurization device is connected with the lower part of the chimney. Waste gas generated by the cupola is collected by the large cooler and the small cooler, dust is collected via the bag dust collector and the spray desulphurization device, and the waste gas exhausted finally is free from pollution.

Description

technical field [0001] The invention belongs to the field of metallurgical casting for smelting metals, in particular to an environment-friendly cupola. Background technique [0002] The cupola is an important equipment for melting molten iron in foundry production. The iron material is melted into molten iron and then poured into the sand mold. After cooling, the casting is obtained by opening the box. Energy-saving and environment-friendly cupola refers to an equipment system, which includes independent combustion chamber, heat exchanger, flue gas cooler, dust collector, induced draft fan, spray equipment and chimney in addition to the cupola body. [0003] In the long-term use, it is found that the existing cupolas in China have many shortcomings. One of the more important problems is that most of the waste gas produced by the cupola during the smelting production process is discharged directly or after some simple treatment, causing pollution to the atmosphere. , thus ...

Problems solved by technology

[0003] In the long-term use, it is found that the existing cupolas in China have many shortcomings. One of the more important problems is that most of the waste gas produced by the cupola during the smelting production process is discharged directly or after some simple treatment, causing pollution to the atmosphere. , which brings many problems to the actual use, hinders the survival and development of foundry enterprises, becomes a bottleneck for the survival of foundry enterprises, and cannot keep up with the pace of social development
