Slurry density measuring device

Abstract

The invention provides a slurry density measuring device. The slurry density measuring device comprises a cleaning brush, a controller and a cylindrical metering tank, wherein the cleaning brush is arranged on a side wall of a desulphurization reaction tower; the cleaning brush is arranged over the metering tank and is connected with a lifting cross plate which can lift along the side wall of thedesulphurization reaction tower; the cleaning brush is suspended below the lifting cross plate; an overflowing opening is formed in a side wall of the upper portion of the metering tank; the overflowing opening is integrally connected with an overflowing tube which extends vertically downwards; a liquid draining opening is formed in the bottom of the metering tank; the liquid draining opening is integrally connected with a liquid draining tube; the liquid draining tube communicates with an overflowing tube; and a liquid feeding solenoid valve and a liquid draining solenoid valve are separatelyarranged on a liquid feeding tube and the liquid draining tube. The slurry density measuring device has the beneficial effects that online sampling of slurry liquid can be realized, slurry density can be measured and calculated automatically, the metering tank can further be automatically cleaned, the degree of automation is high, and the measuring precision is high.

Description

Technical field [0001] The invention relates to a slurry density measuring device. Background technique [0002] At present, with my country’s mandatory regulations on energy conservation and environmental protection, all coal-fired boilers are required to desulfurize and remove dust from the flue gas emitted by environmental protection. Most of the conventional flue gas desulfurization processes use alkaline slurry and The SO2 gas in the flue gas undergoes a contact reaction to reduce the SO2 and smoke in the flue gas. In the operation of the flue gas desulfurization process, the slurry density in the desulfurization reaction tower is a key parameter in the entire desulfurization process. When the slurry density in the desulfurization tower exceeds the limit value, the slurry replacement in the tower should be taken immediately to eliminate part of the high density Slurry, supplement part of fresh desulfurization stock slurry. [0003] At present, there are two more online slurry...

Problems solved by technology

Because the online density meter has strict restrictions on the flow rate of the slurry, the flow rate is high, which affects the measurement accuracy, and the flow rate is low, and the larger particles of dust in the slurry cannot flow through the online density meter smoothly, which is easy to cause damage to the online density meter. jam
