Embodiment Construction

[0036] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present invention, and not to limit the present invention.

[0037] In the present invention, if there is no explanation to the contrary, the orientation words used such as "up, down, left, right" and "inside, outside" usually refer to the orientation or positional relationship shown in the drawings, only for It is convenient to describe the technology and simplify the description, instead of indicating or implying that the device or element referred to must have a specific orientation, be configured and operated in a specific orientation, and therefore is not used to limit the technology.

[0038] In order to remove dust from the gas under high temperature and low resistance operating environment, especially when the temperature is gr...

Abstract

The invention relates to the field of filtering, and particularly relates to a filtering dust remover, which can efficiently filter and remove dust under the operation environment of high temperatureand low resistance. The filtering dust remover comprises an air inlet section (5), a filter main body and an air outlet section (8); the air inlet of the filter main body section is connected to the air inlet section, and the air outlet thereof is connected with the air outlet section; the filter main body comprises more than one filter rooms (1) linked in series on the air flow direction; an aircirculation hole is arranged between adjacent filter rooms; every filter room is filled with a temperature-resisting granular filter medium with preset granularity; the filter medium in every filtering room is transferred and updated according to the tested suitable updating rate; the medium of every filter room is fully used; the air inlet section is provided with a dust containing gas inlet (4),and the gas outlet section is provided with a dust removing air outlet (7). The filtering dust remover can work under the low allowable pressure drop environment, in particular to the condition of being less than 2kPa.

Description

Technical field [0001] The present invention relates to the field of filtration, in particular, to a filter dust collector, and is particularly suitable for a high-efficiency filter dust collector under a high temperature and low resistance operating environment. Background technique [0002] Gas-solid separation technology, represented by coal pyrolysis raw gas dust removal, has such stringent requirements as system allowable pressure reduction (generally less than 2KPa), high-temperature operation (above 400°C), and finer entrained dust (higher particle content below 10μm) Requirements, it is difficult to achieve the expected results by using ordinary gas-solid separation methods, such as: the normal operating pressure drop of the cyclone separator is generally not less than 2KPa, and it is difficult to capture fine particles below 5μm; electrostatic precipitator and bag filter can capture fine However, the ceramic filter is not able to withstand the temperature above 250 ℃; du...
