Description

Technical Field

[0001] This utility model relates to the field of flue gas desulfurization slurry technology, specifically to a flue gas desulfurization slurry preparation system. Background Technology

[0002] Flue gas desulfurization slurry is a chemical solution used to remove sulfur dioxide (SO2) from flue gas. In the flue gas desulfurization (FGD) process, the desulfurization slurry typically contains an absorbent, such as limestone (CaCO3) or lime (CaO), and water. In the absorption tower, the desulfurization slurry comes into countercurrent contact with the flue gas. The SO2 in the flue gas reacts with the calcium carbonate in the slurry to form calcium sulfite (CaSO3) and calcium sulfate (CaSO4). During this process, the calcium carbonate in the slurry neutralizes the acidic gases, thereby achieving desulfurization and reducing environmental pollution. The limestone-gypsum wet flue gas desulfurization process achieves a desulfurization rate of over 95%. The desulfurized flue gas not only has a very low sulfur dioxide concentration but also a significantly reduced dust content.

[0003] Dust not only harms human health, but high concentrations of dust suspended in the air can also reduce visibility at work sites, making safety accidents more likely. It can also accelerate mechanical wear and even cause violent explosions under certain conditions. Therefore, eliminating the hazards of dust has become an urgent task for safe production.

[0016] This invention provides a flue gas desulfurization slurry preparation system. It has the following beneficial effects:

[0017] (1) When preparing limestone slurry, a gas collection hood is installed above the slurry box. When limestone powder is added, the boiling material can be controlled in the pit by the suction dust collection device, so that no dust overflows and the damage rate of nearby equipment is reduced. Powered by compressed air, there is no electrical interference and no electrical hazards. Since there is only gas flow and no mechanical movement during the use of the equipment, it is not easy to be damaged. The maintenance of parts is not considered. The assembly parts can be connected by adhesive. The suction device has no moving parts, making it safer and maintenance-free. It has a compact structure, simple operation, easy installation and carrying. It has an airflow enhancement function, low gas consumption, and saves gas. It solves the problem that dust not only harms human health, but also high concentrations of dust suspended in the air will reduce the visibility of the work site, which is easy to cause safety accidents. At the same time, it accelerates mechanical wear and may even cause violent explosions under certain conditions.

[0018] (2) When the operator uses the device, the position of the limestone powder silo can be supported by the stable base plate and the column. The stability of the limestone powder silo can be effectively improved by setting the arc rod. The material can be added into the limestone powder silo by setting the connecting flange, which makes it easier for the operator to use the device. Attached Figure Description
