Problems solved by technology
Although this kind of filter device can carry out back blowing and cleaning of the filter element through the back blowing soot cleaning device, the cleaning effect is not ideal when thick dust is attached to the surface of the filter element, especially for the "dust accumulation" formed between the filter element and the filter element. "Ash bridge" is difficult to effectively destroy, thus limiting the use of filter devices

The invention discloses a filter device for gas-solid separation and an injection device thereof, thereby effectively removing "ash bridges" formed between filter elements. The filtering device includes a filter element group composed of a plurality of outer filter elements arranged at intervals and installed on the filter element positioning device. The length directions of these filter elements are consistent. Leading part and blowing part, described blowing part comprises the blowing pipe that is arranged in the side gap of filter core and extends along the length direction of filter core, and the peripheral wall of described blowing pipe is distributed with a plurality of blowing ports that act on the side part of filter core, The guide part includes a guide pipe, the air inlet of the guide pipe is used to connect with the compressed air supply device, and the exhaust port of the guide pipe is connected with the air inlet of the blowing pipe. After the above-mentioned blowing device is installed, the dust between the filter elements can be blown directly, and the "ash bridge" formed by dust accumulation between the filter elements can be broken.
Description
technical field [0001] The invention relates to a filter device for gas-solid separation and a blowing device thereof. Background technique [0002] At present, the structure of the filter device used for gas-solid separation generally includes a cylinder body and a plurality of external filter elements arranged at intervals in the cylinder body. The original gas chamber is formed under the orifice plate in the cylinder, and the clean air chamber is formed above the orifice plate. The cylinder of the filter device is provided with an air inlet connected to the original gas chamber and an exhaust port connected to the clean air chamber. The lower part of the cylinder is a conical ash chamber that communicates with the original gas chamber, and the bottom of the conical ash chamber is provided with an ash discharge port; in order to periodically clean the filter element, the upper part of the cylinder is also equipped with a back blowing ash removal port. device. The working...
