Quicklime slaking equipment system

Abstract

The invention discloses a quicklime slaking equipment system which comprises horizontal powerful mixing machines. A waste gas pipeline, a closed filter pond, a spray tower, a purified air pipeline anda fan are sequentially connected onto waste gas exhaust openings of the horizontal powerful mixing machines according to waste gas output and treatment sequences, the spray tower is arranged on the upper portion of the closed filter pond, a waste gas output end of the waste gas pipeline and the bottom of the spray tower are communicated with the upper portion of the closed filter pond, a spray head is arranged on the upper portion of the spray tower, a purified air outlet in the top of the spray tower is connected with the purified air pipeline, a clear water supply pipe is connected onto thespray head, and filter water in the closed filter pond can be delivered onto water adding openings of the horizontal powerful mixing machines by a filter water delivery pump and a filter water delivery pipe. The quicklime slaking equipment system has the advantages that the quicklime slaking rate can be increased, the equipment operation reliability can be improved, quicklime slaking and dust removal can be integrated, and waste gas and waste water zero-discharge effects can be realized.

Description

technical field [0001] The invention relates to the technical field of quicklime digestion equipment, in particular to an equipment system for quicklime digestion. Background technique [0002] Quicklime digestion equipment (also known as quicklime digester) is a special equipment for digesting quicklime into lime milk or lime powder. It produces lime milk or lime powder by mixing quicklime with water to produce digestion reaction. Lime digesters are widely used in industry. For example, quicklime is often used as a sintering flux in the sintering production process, and the quicklime is digested through the digestion equipment in advance to facilitate the strengthening of sintering production and increase the production capacity of the sintering machine. Because quicklime will produce a lot of steam and dust during the digestion reaction, if it is not treated in time, it will pollute the environment. Therefore, a dust removal device must also be provided. [0003] Existi...

AI Technical Summary

Problems solved by technology

[0004] One is that after the quicklime is added with water, the mixture is pushed forward and mixed by the rotation of the double helical blades, and the uniformity of the mixing is poor, thus reducing the digestibility of the quicklime

[0005] The second is that the quicklime is in a semi-solidified state during the process of adding water to digestion. When restarting after stopping, this semi-solidified material in a static state has greater resistance to the double helix, which is prone to the disadvantages of double helix blades being stuck, deformed or falling off.

[0006] The third is that the output of the digester adopting the double-screw propulsion structure is low, and the power required is large when the feeding volume is large, which is prone to equipment tripping

[0007] Fourth, the traditional bag filter is easy to block and needs to be shut down for cleaning and maintenance. It is difficult to continue to work normally, which seriously affects the subsequent sintering production
