Embodiment Construction
[0020] Such as figure 1 and figure 2 As shown, the blast furnace gas rotary pulse bag filter: the upper cylinder (10), the middle cylinder (20) and the lower cylinder (21) are welded to each other to form an integrated structure.
[0021] The upper cylinder body (10) is provided with a release pipe interface (25) and a clean gas outlet (26); the middle cylinder body (20) is provided with a raw gas inlet (29), and the inlet of the raw gas inlet (29) is provided with Raw coal gas distribution device (28); the lower cylinder (21) is equipped with a nitrogen gas clearing device (22), a bag taking device (23), a nitrogen filling pipe (24), an ash discharge port (32) and a heating device (31 ).
[0022] In the upper cylinder (10), the flower plate (16) is circular and directly welded to the inner wall of the upper cylinder. The flower plate (16) is densely covered with filter bag holes (16-1), and the filter bag holes (16-1 ) is oval, a filter bag (17) is installed under each fi...

The invention relates to a rotary pulse bag type dust remover for blast furnace gas. According to the technical scheme, a dispersing pipe port and a pure gas outlet are formed in an upper cylinder body; a coke-oven gas inlet is formed in a middle cylinder body; and a nitrogen unblocking device, a bag taking device, a nitrogen inflating pipe, a dust discharging opening and a heating device are arranged on a lower cylinder body. A pattern card is arranged inside the upper cylinder body; filter bag holes are densely distributed on the pattern board; a filter bag is mounted under the filter bag holes; and a set of an injection device is mounted at the upper part of the pattern card. A pulse air pocket bracket and a pulse air pocket are sequentially mounted at the top of the upper cylinder body; a twisted-pair wire pulse airflow output pipe is arranged inside the pulse air pocket; and one end of the twisted-pair wire pulse airflow output pipe is connected with a pulse valve, and the other end of the twisted-pair wire pulse airflow output pipe passes through the pulse air pocket and the pulse air pocket bracket, extends into the cylinder bodies, and are fixedly connected with a positioning device I. The rotary pulse bag type dust remover provided by the invention is simple in structure; dust cleaning operation can be completed by only arranging one pulse valve, so that the dust removing efficiency can be improved; and meanwhile, the quantity of the cylinder bodies in different processes can be reduced.
Description
technical field [0001] The invention belongs to the technical field of pulse bag type dust removal device. Background technique [0002] At present, it is suitable for the purification of normal temperature and high temperature dust-containing gas and the recovery of dust materials in metallurgy, chemical industry and other fields. The structure is very complicated. The pulse valve and the injection pipe are designed in a one-to-one form. There are many pulse valves and many wearing parts, so there are many problems in the manufacture and maintenance of the equipment. In addition, there are two relatively new types of bag-type dust collectors, one is driven by a motor to rotate the shaft, and the filter bag is rotated and sprayed to clean the dust. The other is driven by a cylinder to rotate the device to carry out rotary blowing and dust removal on the filter bag. The blowing pipes of the above two dust collectors are designed in the form of one-to-one rows of filter bags...
