Embodiment 1

[0146] use as figure 2 In the shown device, before dust removal starts, water is stored in the buffer pool through the water inlet pipe, and the water in the buffer pool flows into the dust removal pool together, and the water level adjustment plate is adjusted to completely cover the water level adjustment hole. When the water level reaches the predetermined water level, close the water inlet pipe, and then adjust the water level in the dust removal pool by adjusting the area and height of the water level adjustment plate to cover the water level adjustment hole. The excess water flows into the overflow water seal pool through the water level adjustment hole. When the overflow water seal When there is too much water in the pool, the overflow pipe can be opened to discharge the excess water.

[0147] The dust flue gas from the dust removal port of the quicklime digester enters the dust collector through the dust removal pipe. The dust removal pipe is inserted into a certain p...

Embodiment 2

[0152] adopted with figure 2 Basically the same equipment, except that the V-shaped filter screen is not arranged under the bracket, dust removal is performed in the same manner as in Example 1, and the dust removal efficiency is 95%.

Embodiment 3

[0158] A method for using quicklime digestion water bath dedusting device, the method comprises the following steps:

[0159] (1) Store water in the buffer pool R103 through the water inlet pipe R502, and the water in the buffer pool R103 flows into the dust removal pool R101 together, adjust the water level adjustment plate R601 to completely cover the water level adjustment hole R605, when the water level in the dust removal pool When the predetermined water level is reached, close the water inlet pipe R502;

[0160] (2) By adjusting the area and height of the water level adjustment plate R601 to block the water level adjustment hole R605 to regulate the water level in the dust removal pool R101, the excess water flows into the overflow water seal pool R102 through the water level adjustment hole R605, when the overflow water seal pool R102 When there is too much water, the overflow pipe R501 can be opened to discharge the excess water;

[0161] (3) Dust and flue gas from t...

Abstract

The invention relates to a dust collecting device for digestion water bath of quick lime. The dust collecting device comprises a de-dusting pool, a dust collector shell, a de-dusting pipeline, an overflow water seal pool, a buffering water pool, a water level adjusting hole and a water level adjusting device, wherein the dust collector shell is located above the de-dusting pool; one end of the de-dusting pipeline is externally connected with a de-dusting interface of a lime digester while the other end passes through the dust collector shell and extends into the de-dusting pool under the dust collector shell; an underwater pipeline nozzle is arranged at one end of the de-dusting pipeline extending into the de-dusting pool; a net structure or a porous structure is arranged at the tail end of the underwater pipeline nozzle; the overflow water seal pool is located on one side of the de-dusting pool; the buffering water pool is located on the other side of the de-dusting pool; the water level adjusting hole is located between the de-dusting pool and the overflow water seal pool and is formed at the lower end on one side of the dust collector shell; a clamping and releasing slot is formed on the outer side of the shell aside the water level adjusting hole; the water level adjusting device comprises a water level adjusting plate, a screw rod and an adjusting valve; the water level adjusting plate is placed in the clamping and releasing slot; the vertical width of the water level adjusting plate is slightly more than the vertical width of the water level adjusting hole.

Description

technical field [0001] The invention relates to the field of quicklime digestion and dust removal in iron and steel sintering plants, in particular to a high-efficiency quicklime digestion water-bath dust collector and quicklime digestion and dust removal sewage treatment method. The method mainly solves the problems of low dust removal efficiency and poor dust removal effect of existing quicklime digestion, environmental pollution of quicklime digestion and dust removal sewage, and how to reuse the dust removal sewage. Background technique [0002] With the development of modern industry and the improvement of people's quality of life, the requirements for environmental protection are getting higher and higher. Safe production and clean production have become the symbol of modern enterprise civilization. [0003] In the iron and steel metallurgical industry, it is generally necessary to sinter iron ore before entering the blast furnace for ironmaking, and quicklime plays an...
