Waste gas treatment equipment for steelworks convenient to it is clean Technical Field The invention relates to the technical field of waste gas treatment, in particular to waste gas treatment equipment for a steel mill, which is convenient to clean. Background Steel mills produce large amounts of exhaust gas during production, which contains various pollutants, such as particulates, sulfur dioxide, nitrogen oxides, etc., which are extremely harmful to the environment and to human health. Therefore, an effective exhaust gas treatment device is of great importance to steel mills, and conventional steel mill exhaust gas treatment devices have problems in terms of cleaning. On the one hand, the internal structure of the equipment is complex, and a plurality of corners and gaps which are difficult to access exist, so that the cleaning work is difficult to fully develop, and part of pollutants remain in the corners and gaps, so that the treatment effect and the service life of the equipment are affected. On the other hand, the cleaning process of some equipment is tedious, a large amount of manpower, material resources and time investment are needed, and the operation cost of enterprises is increased. For example, disassembly and assembly of the equipment is time consuming and may damage the equipment components due to improper operation, and in addition, contaminants in the steel mill exhaust gas are sticky and corrosive and easily adhere to the equipment walls and process components, further increasing the difficulty of cleaning. The long-term accumulated pollutants can also cause equipment blockage and corrosion, reduce the operation efficiency and stability of the equipment, and even cause safety accidents. The existing waste gas treatment equipment of the steel mill generally faces serious problems in the operation process, so that the equipment performance is reduced, the operation resistance is increased, the energy consumption is increased, and even the equipment is forced to be shut down for maintenance. The difficulties in cleaning and maintenance are mainly manifested in high concentration, fine particles, sticky dust (which is extremely easy to adhere, accumulate and harden on the inner wall of the equipment, the surface of the filter bag/polar plate/polar line, the spray layer, the demister blade, the surface of the catalyst, etc., and the dust adhesion problem is more serious especially when the humidity of the exhaust gas is high or the temperature fluctuation causes dew formation.
