Cleaning frame for waste gas purification apparatus

A cleaning system configured to clean a waste gas purification apparatus including an end plate, a filtration component extending from the end plate on a first side of the end plate, and a connecting component supported on the end plate on a second side of the end plate, the second side of the end plate being opposite to the first side of the end plate, the cleaning system comprising:

• a cleaning tank configured to hold a cleaning solution;
• and
• a cleaning frame configured to support the waste gas purification apparatus in the cleaning solution, the cleaning frame including
• a bottom including a channel running through the bottom, and
• a sidewall formed by upward extension from the bottom around the channel, the bottom having a retaining part between the sidewall and the channel, and the sidewall and the retaining part enclosing a holding cavity,
• wherein a dimension of the channel is smaller than a dimension of the end plate of the waste gas purification apparatus, the end plate of the waste gas purification apparatus being supported by the retaining part and configured to seal the channel such that the connecting component is located above the retaining part, and located within the holding cavity, and
• wherein the cleaning frame is configured to maintain the waste gas purification apparatus in a floating position in the cleaning solution with the sidewall of the cleaning frame can at least partially float above the surface of the cleaning solution to maintain the filtration component in the cleaning solution of the cleaning tank and to isolate the connecting component of the waste gas purification apparatus from the cleaning solution.
