Description

TECHNICAL FIELD

[0002] The information disclosed in this Background section is for the purpose of providing context for the disclosure and as such, acknowledges that the information was publicly available prior to the filing date of this patent application and is submitted merely to accelerate the disclosure of the present application.

[0003] In the process of rock wool production, the smelting furnace will produce flue gas containing a large amount of sulfur dioxide, which is one of the main atmospheric pollutants, and needs to be treated by a desulfurization system during production.

[0004] The commonly used desulfurizer for flue gas desulfurization is mainly powder desulfurizer such as quicklime, limestone, sodium hydroxide, etc. It needs to be dissolved in advance before being added to the desulfurization equipment. For example, in the limestone gypsum desulfurization system, the desulfurizer is quicklime, which needs to be mixed with water in a certain proportion in advance and stirred uniformly before being added to the desulfurization system for use.

[0005] The concentration of desulfurizer in the desulfurization slurry directly affects the absorption rate of sulfur dioxide in the desulfurization device. Proper concentration can improve the desulfurization efficiency, and too high or too low concentration will affect the absorption of sulfur dioxide, and even cause scaling or blockage in the desulfurization device. Therefore, whether the unloading device can accurately and stably unload is very important.

[0006] However, the existing unloading device has the following problems, such as: the screw feeder is running all the time, which will interfere with the weighing, and sometimes the feeder and the weighing device do not match, resulting in that the displayed data of the unloading does not match the actual unloading; the powder desulfurizer blocks the inlet and outlet hoses of the feeder, resulting in inaccurate weighing and affecting the preparation of the desulfurization slurry; if the powder desulfurizer is damp, it will cause the desulfurizer to be stuck or blocked in the feeder or the unloading pipe, affecting the accuracy of the unloading amount. Even if the material is stuck or blocked, the staff has difficulty in maintenance, and even cannot determine the blockage position in time, affecting the preparation of the slurry.
