Description

Splash-proof raw material bin of desulfurization system

Technical Field

The utility model belongs to the technical field of feeding equipment of a desulfurization system, and particularly relates to a splash-proof raw material bin of the desulfurization system.

Background

The desulfurization system adopts the scheme of SDS desulfurization and a bag type dust collector, and purifies the waste gas generated by the hot blast stove into qualified flue gas for discharge. And (3) injecting finely ground baking soda into the front part of the flue, quickly reacting sulfur dioxide and other acid gases in the flue gas in the flue reaction section with the baking soda to remove the sulfur dioxide and other acid gases efficiently, removing dust from the reaction product by a cloth bag, and discharging qualified flue gas into a chimney. The desulfurizer baking soda raw material conveyed by the desulfurizer storage and transportation system enters a raw material bin and passes through a discharge valve to a receiving hopper, and is ground into particles with D90 less than or equal to 20 mu m by a grinding machine system. The mixed gas of the fine powder at the outlet of the mill and the negative pressure air at the inlet of the mill enters the desulfurization reaction zone through the outlet pipeline of the mill, thereby purifying the flue gas. The raw material bin is used for storing raw material baking soda, and after the material of the receiving hopper is used up, the raw material bin is used for supplementing materials, and the process is repeated until the material of the raw material bin is used up, so that the raw material bin is not fed due to the influence of equipment and environment, at this time, the system is usually used for carrying out gas impact by using a nitrogen gun function of the system to enable the raw material bin to be fed or a worker in a contact site to knock the wall of the bin by a large hammer to knock the bin to enable the raw material bin to be fed to the receiving hopper. Because the feed inlet of the raw material bin feeds materials at any time, a sealing cover cannot be installed, the feed inlet of the raw material bin is in an open state, when the nitrogen gun is used for impacting, raw material baking soda is very easy to spray out of the feed inlet due to high gas pressure, so that on-site environment pollution is caused, and in order to avoid splashing, small soda can only fall down by rapping with a large hammer by on-site staff, so that the labor intensity of staff can be increased.
