Embodiment
[0028] Such as figure 1 A combined dust collector for combustible gas is shown, including a cylinder body and an air inlet pipe 10 and an air outlet pipe 4 arranged on the cylinder body. It is characterized in that the inside of the cylinder body is sequentially assembled with the first Perforated plate 13, the second perforated plate 11 and the third perforated plate 9, and the cylinder is divided into filter chamber, clean air chamber, gravity settling chamber and feeding chamber from top to bottom. The gravity settling chamber carries out the gravity settling of the first-stage large-particle dust, and the cyclone separator 6 is installed between the second porous plate 11 and the third porous plate 9 to carry out the second-stage centrifugal separation and discharge it through the feeding chamber. For dust particles, the filter chamber is provided with a gas filter for third-stage precision filtration.
[0029] The cylinder includes an elliptical head 2, a cylindrical cyl...

Abstract
The invention relates to a combined dust collector for combustible gas, which comprises a cylinder body and an air inlet pipe (10) and an air outlet pipe (4) arranged on the cylinder body, and the inside of the cylinder body is sequentially assembled from top to bottom One perforated plate (13), the second perforated plate (11) and the third perforated plate (9), and the cylinder body is divided into filter chamber, clean air chamber, gravity settling chamber and The feeding chamber, the gravity settling chamber carries out the first-stage large particle dust separation by gravity settling, and the cyclone separator (6) is installed between the second porous plate (11) and the third porous plate (9). ), carry out the second stage of centrifugal separation, and remove the dust particles through the feeding chamber, and the filter chamber is provided with a gas filter for the third stage of precision filtration. Compared with the prior art, the invention has the advantages of high efficiency, low resistance, stable and reliable operation, high dirt holding capacity, high tolerance and the like.
Description
technical field [0001] The invention relates to a dust collector, in particular to a combined dust collector for combustible gas. Background technique [0002] The purification technology of combustible gas under pressure is a key link in gas transmission, distribution and use, and its efficiency directly affects the performance and economic cost of subsequent pressure regulation distribution and combustion devices. At present, on the basis of digesting and absorbing foreign advanced gas purification technologies, my country has developed a variety of gas purification technologies for various working conditions of pressurized combustible gases. [0003] At present, the gas purification for natural gas distribution stations is mainly of filter cartridge and filter element type, the purpose is mainly to protect the subsequent pressure regulation and metering devices of the gas distribution station. This type of gas purification device is mainly suitable for occasions with sma...
