The invention discloses a coal economizer with an efficient dust clearing function. The coal economizer comprises a coal economizer body. A gas input pipe is arranged at the lower end of the right endface of the coal economizer body. A gas input pipe is arranged at the upper end of the right end face of the coal economizer body. A dust removing device fixedly connected to the gas input pipe and the right end of the gas input pipe is arranged on the right side of the coal economizer body. Three filtering cavities are uniformly distributed in the dust clearing device up and down. A filtering plate is fixedly arranged on the inner left side of each filtering cavity. Ventilating openings are formed in the left wall and the right wall of each filtering cavity in a communicating manner. A gas collecting channel is formed in the left side of each ventilating opening in the left side in a communicating manner. The lower ends of the gas collecting channels communicate with the gas input pipe.According to the coal economizer, smoke is dispersed and filtered, then the purified smoke is collected and input into the coal economizer to be utilized, the dust clearing efficiency is improved, meanwhile, dust generated by filtering can be exhausted in time, the situation that due to dust accumulation, filtering of the smoke is influenced is avoided, flowing of gas is utilized to serve as power, and thus the dust clearing frequency can be adjusted according to the speed of gas ventilating.
Description
technical field [0001] The invention relates to the technical field of coal economizers, in particular to a coal economizer with ash cleaning function. Background technique [0002] When the boiler is burning, it will produce flue gas with a lot of heat. If the flue gas is directly removed, the heat will be wasted, resulting in waste of resources and low utilization rate. The economizer can utilize the heat in the flue gas , Absorb the waste heat in the flue gas and improve the utilization rate of resources. If the flue gas is directly passed into the economizer, the dust in the flue gas will accumulate in the economizer, which will reduce the heat absorption capacity of the economizer, reduce the use effect and service life, therefore, the flue gas needs to be cleaned The ash is then passed into the economizer. The present invention illustrates a device capable of solving the above-mentioned problems. Contents of the invention [0003] technical problem: [0004] Ordi...
