Abstract

The invention provides a top end smoke discharge device and method used for sintered product production. The top end smoke discharge device comprises a kiln body. The inner portion of the kiln body isdivided into a product kiln entering section and a product kiln leaving section. The product kiln leaving section is sequentially provided with a second kiln door and a first kiln door in the kiln car advancing direction. A main smoke discharge pipeline is arranged above the kiln body. A draught fan is arranged on the portion, close to a pipeline outlet, of the main smoke discharge pipeline. A main smoke discharge valve is arranged on the second kiln door. A top branch smoke discharge port is formed in the area, corresponding to the portion between the first kiln door and the second kiln door, of the top of the kiln body and communicates with the main smoke discharge pipeline through a top branch smoke discharge pipeline. A side wall body of the product kiln entering section is provided with side wall branch smoke discharge ports and corresponding side wall branch smoke discharge pipeline valves. The side wall branch smoke discharge ports communicate with the main smoke discharge pipeline through side wall branch smoke discharge pipelines correspondingly arranged on the top of the kiln body. According to the device, by regulating opening sizes of all the valves, the temperature differences in a whole kiln are reduced, and the gas flow speed and the ventilation amount can be more uniform; and therefore the product quality is improved, energy conservation is achieved, and the heat loss is reduced.

Description

technical field [0001] The invention belongs to the technical field of sintered product production, and relates to a top smoke exhaust device and method for sintered product production. Background technique [0002] In recent years, with the rapid development of the sintered product industry, the technology and equipment of the sintered product industry have become more and more advanced, especially the key equipment for sintered products - tunnel kiln. The advanced structure of the tunnel kiln can help enterprises greatly improve product quality and Save fuel. Most of the traditional tunnel kilns use the side wall smoke exhaust method, especially the wide-section tunnel kiln, which is easy to cause uneven wind speed in the kiln. The quality of sintered products. At the same time, due to the uneven air flow in the kiln, it will also cause the problem of excessive heat consumption. Contents of the invention [0003] The purpose of the present invention is to solve the pr...
