Problems solved by technology

The CYBAG filter invented by Chinese patent CN98114710.0 is to install a bag filter on the top of the cyclone separator. It needs to add a Venturi tube to increase the speed. The efficiency is high, but the structure is complicated and the pressure drop is large.
The obvious disadvantage of this cyclone separator is that its energy loss is large, the pressure drop is large, and the pressure drop combined with the filter is also large

Embodiment 1

[0027] Such as figure 1 As shown: when the dust collector of the present invention is in use, the gas containing dust particles enters the tangential inlet 1 of the DC cyclone separator, and the dust particles are thrown to the wall of the device under the action of centrifugal force, and move spirally along the cyclone separation wall surface, and finally Fall into the ash hopper 7 below and discharge from the discharge port 8; at the same time, the cyclone-separated gas moves down along the center of the cavity of the DC cyclone separator and enters the exhaust pipe 5, and the gas passes through the upper end of the exhaust pipe 5 to install The filter element 4 enters in the 5, and further purifies the gas. When pulse recoil is used, the dust deposited on the filter element 4 will also fall into the ash hopper 7 below and be discharged from the discharge port 8. At the same time, in order to facilitate disassembly and replacement of the filter element 4, the cylindrical bo...

Embodiment 2

[0029] Such as figure 2 As shown: when the dust collector of the present invention is in use, the gas containing dust particles enters the tangential inlet 1 of the DC cyclone separator, and the dust particles are thrown to the wall of the device under the action of centrifugal force, and move spirally along the cyclone separation wall surface, and finally Discharge from the discharge port 8; at the same time, the gas separated by the cyclone moves horizontally along the center of the cavity of the DC cyclone separator and enters the exhaust pipe 5, and the gas enters the exhaust pipe 5 through the filter element 4 installed at the inlet end of the exhaust pipe 5, and further Purified the gas. When pulse recoil is used, the dust deposited on the filter element 4 will also be discharged from the discharge port 8. In order to facilitate disassembly and replacement of the filter element 4, the cylindrical body 2 of the DC cyclone separator is designed as a detachable connection...

Abstract

The invention discloses a flame-retardant high-efficiency low-resistance dust remover. The flame-retardant high-efficiency low-resistance dust remover comprises a direct current type cyclone separator and is characterized in that a flame-retardant filter element (4) is arranged on an inlet of an exhaust pipe of the direct current type cyclone separator and the flame-retardant filter element (4) is made by adopting a low-resistance high-efficiency ultramicropore paper filter drum. According to the flame-retardant high-efficiency low-resistance dust remover, the flame-retardant filter element is arranged in the direct current type cyclone separator, the characteristics of the separator and a filter are organically combined, higher separation efficiency is guaranteed while total pressure drop can be reduced, and energy consumption is reduced while cost is reduced; and pressure drop of the selected direct current type cyclone separator is lower, the low-resistance high-efficiency filter element made by adopting the ultramicropore paper filter drum is selected, initial filteration resistance is low and less than 200Pa and purification efficiency is high, and the purification efficiency on micronic dust with grain size of more than 0.5 micron can be 99.9%; the filter element is convenient to dismount, replace and clean, and the direct current type cyclone separator is connected in a dismountable manner, so that the flame-retardant high-efficiency low-resistance dust remover can be applied to a special working condition place requiring flame retardancy.

Description

technical field [0001] The invention relates to gas purification and dust removal equipment in the field of gas purification, in particular to a flame-retardant high-efficiency and low-resistance dust collector with low pressure drop, high separation precision, low filtration resistance and small volume. Background technique [0002] Dust collectors are widely used and can be applied to many industrial productions to accomplish different process purposes, such as: purifying dispersion media, recycling dispersed materials, purifying exhaust gases, protecting follow-up equipment, etc. There are also many types of dust collectors, which can be divided into: inertial force (gravity) dust collectors, centrifugal force dust collectors, electrostatic dust collectors and filters according to the separation efficiency from low to high. To ensure high separation accuracy, filters must be used. Although the separation accuracy of the filter is very high, the filter is not suitable fo...
