Abstract
The invention discloses a scale depositing disc and a device for capturing solid substances in gas. The scale depositing disc comprises a tower tray plate and a scale depositing device arranged on the tower tray plate, the device for trapping the solid substances in the gas comprises an upper sealing head, a shell and a lower sealing head, a scale depositing disc is arranged in the device, a flow field flow state suitable for adhesion and aggregation of the solid substances is constructed by arranging the scale depositing disc with a flow blocking and equalizing function, the solid substances in the gas are intercepted, trapped and stored, and the solid substances in the gas can be collected and stored. The gas purification is realized; and the long-period stable operation of the device is ensured. The device for capturing the solid substances in the gas is simple in structure, small in pressure drop in the using process, capable of stably running for a long period and suitable for intercepting and storing dust in a gas phase.
Description
technical field [0001] The invention belongs to the technical field of chemical engineering and relates to a fouling pan and a device for collecting solid matter in gas. Background technique [0002] Most of the chemical process produces process gas. With the improvement of environmental protection regulations on emission standards, this part of the gas needs to remove solid particles and / or purify it before being discharged. For example, the fly ash in the flue gas produced in the production process of a coal-fired power plant must be removed before it leaves the chimney. The entrainment of solid dust in the gas generated in the chemical production process will cause fouling and blockage of the device, which seriously restricts the long-term stable operation of the device. The dust entrained in this part of the gas has good adhesion and aggregation. Dust adhesion refers to the attraction between different molecules, such as the adhesion between powder particles and the wal...
