Abstract
Description
Technical Field
[0001] The present application relates to the technical field of flue gas treatment, and in particular to a mobile loading trolley. Background Art
[0002] Waste incineration is a process in which the combustible components in the garbage react violently with the oxygen in the air in a high-temperature incinerator, converting into high-temperature combustion gas and stable solid residue, and releasing heat. It has important applications in the field of urban waste treatment. For the silos in the flue gas treatment system of waste incineration power generation, such as activated carbon silos, slaked lime silos, cement silos, etc., the current main method is to use the feed truck with its own air pump to connect to the feeding pipe of the silo to feed the material. There are also electric hoists to lift ton bags to the top of the silo and pour them into the silo, or ton bag feeders cooperate with their matching fans to feed. Although the feeding truck with its own air pump has the advantages of simple structure and easy feeding, it is not easy to find matching feeding trucks with pumps in remote areas, and the applicability is poor. Electric hoists or ton bag feeders require personnel to be present to feed bags one by one, which is slow and easy to cause dust pollution. The site needs to be cleaned after feeding. Storing ton bags will also reduce the utilization rate of the site ground, and the labor cost and equipment cost are high, so it needs to be improved. Summary of the invention
