Description

Technical Field

[0001] This utility model relates to the field of rotary kiln technology, specifically to a dust collection chamber at the kiln head for a multifunctional rotary kiln. Background Technology

[0002] Rotary kilns are common industrial kilns, widely used in metallurgy, metallurgical waste recycling, municipal and industrial waste incineration, material drying, calcination, and non-ferrous metal volatilization smelting. The high-temperature flue gas generated during the rotary kiln production process is generally treated by pulse dust collectors, electrostatic precipitators, and water film dust collectors.

[0003] Based on the existing design of the dust collection chamber at the kiln head for multi-functional rotary kilns, pulse dust collectors are the most popular choice for dust removal due to their high dust collection efficiency and low investment. However, during operation, they are prone to condensation or burning of filter bags, causing significant problems for production. This is especially true for highly acidic flue gas with high condensation temperatures and when the flue gas temperature fluctuates greatly during production. If the cooling area is too small, the flue gas temperature can easily become too high, making it difficult to collect dust. Therefore, it is necessary to change and adjust the flue gas conveying connection line and the direction of flue gas flow to regulate the flue gas cooling area.

[0004] Now, a novel dust collection chamber for the kiln head of a multifunctional rotary kiln is proposed to solve the above-mentioned problem. Summary of the Invention

[0005] The purpose of this invention is to provide a dust collection chamber at the kiln head for a multifunctional rotary kiln, in order to solve the problems mentioned in the background art, such as the inconvenience of dust collection, the need to change and adjust the flue gas conveying connection line and the direction of flue gas flow, and the need to adjust the flue gas cooling area.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a dust collection chamber for a kiln head in a multifunctional rotary kiln, comprising a support frame and support legs. Support legs are fixedly connected to the four corners at the bottom of the support frame. A dust collection chamber body is fixedly connected to the top of the support frame. A feed inlet is provided on the left side of the dust collection chamber body. A heat-resistant pipe is provided on the left side of the feed inlet. A first valve is fixedly connected between the feed inlet and the heat-resistant pipe. A cooling water tank is fixedly connected to the top of the dust collection chamber body. A forward-oriented herringbone pipe is fixedly connected to the top of the dust collection chamber body.

[0007] As a further technical solution of this utility model, the bottom end of the unidirectional herringbone pipe is embedded inside the cooling water tank, and the unidirectional herringbone pipe is connected to the interior of the dust collection chamber body.
