Description

Technical Field

[0001] The utility model relates to the technical field of ferroalloy processing, in particular to a spray tower for smoke and dust treatment. Background Art

[0002] Ferroalloy, in a broad sense, refers to a product that is added to molten iron as a deoxidizer, element additive, etc. during steelmaking to give the steel certain characteristics or meet certain requirements. The intermediate alloy composed of iron and one or several elements is mainly used in steel smelting. In the steel industry, all intermediate alloys used for steelmaking, whether they contain iron or not (such as silicon-calcium alloy), are generally called ferroalloys; the flue gas generated during the production process of ferroalloys needs to use a spray tower. The spray tower is a gas purification and treatment equipment, which is widely used in pre-treatment of industrial organic waste gas treatment, waste gas purification, dust removal, etc., with a good purification effect. Because its working principle is similar to the spray process, it is called a spray tower.

[0003] For example, Chinese patent application No. 202321713618.3 discloses a high-efficiency spray tower, including a spray tower body, characterized in that at least two groups of spray pipes are arranged inside the spray tower body, a plurality of spray heads are installed on the spray pipes, an air outlet pipe is arranged at the top of the spray tower body, and an air inlet pipe is arranged at the bottom of the spray tower body. The utility model provides an air inlet pipe at the bottom of the spray tower body, which includes an air inlet pipe main pipe, an annular branch pipe and a connecting pipe. The number of annular branches is two, including an outer annular branch pipe and an inner annular branch pipe. The outer annular branch pipe and the inner annular branch pipe are connected through the air inlet pipe main pipe and the connecting pipe. The annular and outer pipe design enables the exhaust gas to be evenly distributed inside the spray tower body, thereby increasing the purification effect of the spray tower.

[0004] However, in the above scheme, although a flue gas filtering device is added to improve the flue gas purification effect, the flue gas directly enters the spray tower. The flue gas entering the tower may go directly upward, resulting in uneven flue gas in the tower and poor spraying effect. In order to solve the above problems, we designed a spray tower for smoke dust treatment. Utility Model Content
