Small-size coal-fired boiler flue gas dedusting device

Abstract

The invention provides a small-size coal-fired boiler flue gas dedusting device. The small-size coal-fired boiler flue gas dedusting device comprises an untreated gas pipe, a separation cylinder, an eddy flow plate blade, a purified gas pipe, a dust outlet pipe, a gate valve, eddy flow plate supporting plates, an eddy flow blind plate, an eddy flow plate hood cylinder, an eddy flow plate main body, a flue gas deodorizing cleaning management structure, a flue gas purifying absorbing ball structure, and a purified flue gas sampling pipe structure; the untreated gas pipe is connected with the left end inlet of the flue gas purifying absorbing ball structure through threaded connection. The small-size coal-fired boiler flue gas dedusting device is provided with the untreated gas pipe, the separation cylinder, the eddy flow plate blade, the purified gas pipe, the dust outlet pipe, the gate valve, the eddy flow plate supporting plates, the eddy flow blind plate, the eddy flow plate hood cylinder, and the eddy flow plate main body, so that it is beneficial for rapid assembling and dismounting, the structure is simple, and operation is convenient. The small-size coal-fired boiler flue gasdedusting device is provided with a cleaning pipe main body, a blocking plate, a hollow lower bottom plate, a deodorizing absorbing core, a hollow upper bottom plate, and a cleaning door, so that it is beneficial for deep filtering of impurities and speculiar smell in flue gas, and is convenient for cleaning.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, and in particular relates to a small coal-fired boiler flue gas dedusting device. Background technique [0002] For small coal-fired boilers below 20t / h, bag filter or electrostatic precipitator is generally used for flue gas dust removal. The investment of bag filter and electrostatic precipitator is relatively high, the energy consumption is relatively high, and the maintenance cost is also relatively high. [0003] The current coal-fired dedusting devices are roughly divided into two categories, one is dry dedusting, and the other is wet dedusting. The dry method mainly includes cyclone dust removal, electrostatic dust removal and bag dust removal. The wet method mainly includes water film dust collector, spray tower, Venturi scrubber and swirl plate tower, etc. The design and structure of the above-mentioned devices are relatively complicated, and the construction cost is ...
