Mobile particle bed dust filter device with automatic particle size stratification and filter material stratification replacement

Abstract

The invention provides a moving particle bed dust filter device with automatic particle size stratification and filter material layer replacement, which belongs to the technical field of dust-containing gas filtration and purification. The device includes a feed inlet, an offset feed channel, a particle size distribution pre-separator, a material layer thickness adjustment baffle, a particle filter material, a flue gas inlet channel, an anti-arch movable wall panel, and a layered discharge telescopic adjustment panel , discharge port, mobile discharge platform, flue gas outlet channel. There is an offset feed channel and a particle size distribution pre-separator below the feed inlet. The lower part of the particle size distribution pre-separator is connected to the thickness adjustment baffle of the material layer, and the material layer thickness adjustment baffle is connected to the flue gas inlet channel. The channel is connected with the anti-arching movable wall plate, the discharge port is located at the lower part of the device, and the lower part of the discharge port is provided with a mobile discharge platform. The device has the advantages of simple structure, convenient operation, adjustable particle layer thickness, no moving parts in the filter material layer, wide temperature range, suitable for both non-condensable dust filtration and purification, and also suitable for condensation dust filtration and purification.

Description

technical field [0001] The invention relates to the technical field of dust-containing gas filtration and purification, in particular to a moving particle bed dust filtration device with automatic particle size stratification and filter material stratification replacement. Background technique [0002] In 2010, the energy consumption of metallurgy, chemical industry, building materials and other industries accounted for about 70% of China's total industrial energy consumption and 46% of the global industry's energy consumption. According to statistics in 2015, in China's total industrial energy consumption, residual energy emissions accounted for 48%, equivalent to 970 million tons of standard coal. Among them, the average energy utilization efficiency of industrial furnaces is only 33%, the exhaust heat loss accounts for about 17% of the total industrial energy consumption and about 35% of industrial waste energy emissions, which is equivalent to 340 million tons of standar...
