Embodiment 1

[0027] This embodiment provides a device for crushing and dust-free ash discharge of hydraulic pins at the bottom of the tower, the structure of which is as follows: figure 1 , figure 2 As shown, it includes a funnel-shaped desulfurization tower silo 1 and a bottom hydraulic flashboard 4. The bottom hydraulic flashboard 4 is a symmetrically arranged two-way flashboard. Two-way four-row pins, the two-way four-row pins are symmetrically provided with two rows of pins on both sides, the top of the flat pin 3 is connected to the bottom outlet of the desulfurization tower silo 1, and two symmetrically installed on the side wall of the desulfurization tower silo 1 An inclined pin 2, the acute angle between the pin 2 and the side wall of the desulfurization tower silo 1 is 15-75°; the bottom hydraulic insert 4 is provided with a tower bottom dust cover 7, and the tower bottom dust cover 7 is on both sides A first dust removal pipeline 5 and a second dust removal pipeline 6 are resp...

Embodiment 2

[0031] This embodiment provides an application method of a hydraulic pin crushing and dust-free ash discharge device at the bottom of the tower. The method is as follows:

[0032] (1) Install two-way four-row pins above the bottom hydraulic plug-in board with two-way plug-in board, and two rows of plug-in pins are symmetrically arranged on both sides, and two inclined pins are symmetrically installed on the side wall of the desulfurization tower silo. Hydraulic pin;

[0033] (2) When the ash discharge device is working, when there is a large block at the bottom of the tower blocking the discharge port, stop the truck at the discharge port, and notify the central control room to open the dampers of the two additional fans to 100%, and increase the first dust removal pipeline and the second 2. The negative pressure of the dust removal pipeline;

[0034](3) Close the valve port of the bottom hydraulic plug-in plate, and then insert two rows of pins on both sides into the bottom ...

Abstract

The invention discloses a tower bottom hydraulic contact pin breakage dust-free ash discharge device. The device comprises a funnel-shaped desulfurizing tower stock bin and bottom hydraulic insertion plates. The bottom hydraulic insertion plates are two-way insertion plates symmetrically arranged. Flat contact pins are arranged above the bottom hydraulic insertion plates and are two-way four-row contact pins. The two-way four-row contact pins are four rows of contact pins symmetrically arranged on the two sides respectively. The upper portions of the flat contact pins are connected with a bottom outlet of the desulfurizing tower stock bin. Two inclined contact pins are symmetrically installed on the side wall of the desulfurizing tower stock bin. A tower bottom dust cover is arranged below the bottom hydraulic insertion plates, the two sides of the tower bottom dust cover are provided with a first dust removal pipeline and a second dust removal pipeline respectively, and the first dust removal pipeline and the second dust removal pipeline are connected with an inlet flue duct and an outlet flue duct of a desulfurizing tower respectively. The invention further discloses an application method of the tower bottom hydraulic contact pin breakage dust-free ash discharge device. The tower bottom hydraulic contact pin breakage dust-free ash discharge device and the application method solve the problem that large desulfurizing tower bottom blocks block a discharge port, labor intensity is relieved, the labor environment is improved, labor cost is saved, and stable desulfurizing operation is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of metal smelting, and relates to an ash-releasing device, in particular to a dust-free ash-releasing device for crushing hydraulic pins at the bottom of a tower and an application method thereof. Background technique [0002] In the field of metal smelting technology, 2×180m 2 Desulfurization In the production process, the desulfurizer CaO is mixed with water to produce Ca(OH) 2 SO in desulfurization tower and high temperature flue gas 2 A chemical reaction occurs and the main component is CaSO 4 , CaSO 3 , CaCO 3 Most of the desulfurization ash enters the bag filter with the flue gas and is collected in powder form. Some of them are large in size, and the heavier ones will directly fall into the lower silo of the desulfurization tower, becoming loose tower bottom ash. In addition, part of the mixture sticks to the wall of the sulfur tower to form a compacted material. 1. When the working conditions c...
