Description
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.
