Description

Device for solving problems of wet desulphurization lime blockage and upward steam channeling in ball mill

Technical Field

The utility model relates to a desulphurization unit technical field, concretely relates to solve wet flue gas desulfurization lime and scurry the device of problem on the pipeline at the jam of screw feeder to ball mill pipeline and ball mill steam.

Background

At present, the environment-friendly desulfurization engineering of domestic iron and steel companies mostly adopts a lime-gypsum method desulfurization process, lime slurry enters a desulfurization tower and is atomized by a spray head to react with sulfur dioxide in flue gas, and finally gypsum is formed. The wet desulphurization process is mature, but sometimes the desulphurization pulping system is shut down due to process or equipment reasons, lime can be blocked from a conveying pipeline from a screw feeder to a ball mill in the pulping process, the desulphurization system is shut down, the smoke emission exceeds the standard, not only is the enterprise production influenced, but also the environment is damaged.

Meanwhile, the personnel have great danger during ash adding. When the slurrying is carried out to the on-spot ash that adds, because lime calcium oxide content is about 90%, lime is by lime storehouse through screw conveyer pipeline to ball mill, the lime meets the water and takes place exothermic reaction, produce a large amount of steam, because steam does not have the place of exhausting, cause steam to prolong to add grey pipeline and scurry, cause the inside lime of pipeline to bond, time leads to the fact the pipe blockage for a long time, steam is scurry on the while and is driven the lime and scurry up, because the lime fineness is 200 meshes, steam drives the lime and scurries from the screw feeder observation hole, personnel's eyes burn easily, there is the potential safety hazard.

In order to solve the problems, a novel device for solving the problems of blockage of the wet desulphurization lime ash in the conveying pipeline from the screw feeder to the ball mill and upward movement of steam in the ball mill along the pipeline is particularly necessary.

SUMMERY OF THE UTILITY MODEL

To exist not enough on the prior art, the utility model aims to provide a solve the device that the problem was scurried on wet flue gas desulfurization lime blockked up and the ball-mill internal steam, simple structure, reasonable in design, the pipeline is difficult for blockking up, guarantees desulfurization system's normal operating, prevents simultaneously that steam from scurring outward, and the security is higher, and the practicality is strong, easily uses widely.

In order to achieve the above purpose, the present invention is realized by the following technical solution: the device of problem is scurried on steam in solution wet flue gas desulfurization lime blocks up and the ball mill, including screw feeder, ball mill, pipeline, deashing mouth and compressed air pipeline, screw feeder's export is connected with the entry of ball mill through pipeline, pipeline on install the deashing mouth of the interior lime of pipeline of being convenient for clear away and prevent that steam from scurring on the compressed air pipeline.

Preferably, the ash cleaning port is arranged above the conveying pipeline at the inlet of the ball mill.

Preferably, the compressed air pipeline is arranged on a conveying pipeline positioned at the lower part of the ash removing port; the end part of the compressed air pipeline is connected with an air compressor.

The utility model has the advantages that: the device ensures that the pipeline from the screw feeder to the ball mill is smooth, ensures the normal operation of the desulfurization system, prevents the outward channeling of steam, and has higher safety and wide application prospect.

Drawings

The present invention will be described in detail with reference to the accompanying drawings and specific embodiments;

fig. 1 is a schematic structural diagram of the present invention.

Detailed Description

In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention is further described below with reference to the following embodiments.

Referring to fig. 1, the following technical solutions are adopted in the present embodiment: the device for solving the problems of lime blockage in wet desulphurization and upward steam channeling in the ball mill comprises a screw feeder 1, a ball mill 2, a conveying pipeline 3, an ash removing port 4 and a compressed air pipeline 5, wherein an outlet of the screw feeder 1 is connected with an inlet of the ball mill 2 through the conveying pipeline 3, and the conveying pipeline 3 is provided with the ash removing port 4 and the compressed air pipeline 5 which are convenient for removing lime in the pipelines; the ash cleaning port 4 is arranged above a conveying pipeline at the inlet of the ball mill 2, and the compressed air pipeline 5 is arranged on the conveying pipeline 3 positioned at the lower part of the ash cleaning port 4.

This embodiment installs deashing mouth 4 additional in the entry pipeline top of ball mill 2, can clear up the lime in screw feeder to ball mill section pipeline 3 through deashing mouth 4, guarantees that the pipeline is unblocked not blockking up, installs compressed air pipeline 5 additional in lower pipeline department simultaneously, and compressed air pipeline 5's tip is connected with air compressor, injects compressed air into compressed air pipeline 5 through air compressor, prevents effectively that steam from scurrying outward.

Under the existing production condition, the method eliminates the factors influencing the safe production of desulfurization, solves the problems of blockage of the wet desulfurization lime from the spiral feeder to the ball mill pipeline and upward channeling of steam in the ball mill along the pipeline, ensures the normal operation of a desulfurization process system, ensures the operation of enterprise production, reduces the potential safety hazard, informs that the smoke emission reaches the standard, protects the environment and has wide market application prospect.
