Problems solved by technology

The water washing method has high energy consumption, large water consumption, long process, secondary pollution, and is limited by climatic conditions; the pre-spray adsorption method is often not ideal due to insufficient active powder quantity or untimely supply, and still occurs. The phenomenon of tar blocking the filter bag; the flue gas adsorption and purification device has been greatly improved compared with the previous two methods, and can achieve better adsorption effect, but there are still some problems: it is easy to form a "bridge" when the lower hopper is unloading, It affects the normal update of the particle layer; the shell of the adsorption device is mostly cylindrical, which brings a lot of inconvenience to the maintenance work of the field workers; the adsorption device and the bag filter are connected by pipes, and the coke is easily sucked into the bag The dust collector damages the bag and shortens the service life of the filter bag

Abstract

The invention relates to an integrated multi-purification device for dust containing sticky material like tar. The device is characterized by comprising an adsorption purification unit, a terminal purification unit, a pressure-equalizing pre-separation section, an air inlet collecting pipe, an air outlet collecting pipe, a dust trough, and an unloading and discharging system, wherein the smoke inlet side of the adsorption purification unit is connected with the air inlet collecting pipe; the pressure-equalizing pre-separation section is arranged between the adsorption purification unit and the terminal purification unit; the smoke outlet side of the terminal purification unit is connected with the air outlet collecting pipe; the unloading and discharging system is arranged at the lower part of the adsorption purification unit; and the dust trough is arranged at the lower part of the terminal purification unit. The device integrates the functions of coke adsorption, gravity settling and bag type dust removal, and can realize multi-purification processing of smoke containing sticky material like tar; the purification effect is good; and the device has a long service life.

Description

technical field [0001] The invention relates to an integrated device for multiple purification of viscous dust containing tar and the like. Background technique [0002] The flue gas discharged from the top-charging and tamping coke ovens contains tar and other viscous substances during coal charging. The viscous substances contained in the flue dust must be removed before entering the bag filter, otherwise the filter bag will be blocked and the resistance of the filter bag will increase. Large, which not only affects the normal operation of the dust collector but also shortens the service life of the filter bag. At present, water washing, pre-spraying or adsorption by flue gas adsorption and purification devices are often used to solve the problem of sticky dust adhesion, but there are certain limitations. The water washing method has high energy consumption, large water consumption, long process, secondary pollution, and is limited by climatic conditions; the pre-spray ad...
