Description

Automatic smoke filtering and dust removing equipment

Technical Field

The utility model relates to the technical field of flue gas purification treatment equipment, in particular to automatic flue gas filtering and dust removing equipment.

Background

Smoke is a mixture of gas and smoke dust, and is a main cause of pollution to the atmosphere of residential areas. The components of the flue gas are complex, the gas comprises water vapor, sulfur dioxide, nitrogen, oxygen, carbon monoxide, carbon dioxide, hydrocarbon, oxynitride and the like, and the smoke dust comprises ash, coal particles, oil drops, pyrolysis products and the like of the fuel; therefore, the pollution of the smoke to the environment is the combined pollution of various toxicants, the harm of the smoke to the human body is related to the size of particles, and the harm to the human body is more fly ash with the diameter smaller than 10um, and especially the hazard of the fly ash with the diameter of 1-2.5um is the largest.

The boiler is in the in-process of using the unavoidable flue gas that produces the dust, the boiler removes dust just separates the dust in the boiler from the flue gas, thereby reduce dust pollution and be favorable to further carrying out desulfurization and denitration treatment to the flue gas, wherein, need inhale the flue gas that the boiler contains the dust in the boiler flue gas dust removal through the fan negative pressure in the flue gas dust removal purifier, filter the particulate matter in the flue gas and deposit through the filter core in the flue gas dust removal purifier, discharge after filtering the particulate matter, in the flue gas filtration process, need discharge the flue gas after the filter screen of filter core, filter the particulate matter in the flue gas through the filter screen, the flue gas particulate matter adsorbs in the mesh of filter screen in the filtration process, because carry out the filtration work to the flue gas for a long time back, thereby too much flue gas particulate matter adsorbs in the mesh of filter screen and causes filter screen or filter bag jam, and then cause filter screen or filter bag air output to reduce, influence filtration efficiency, cause the condition that gas can't discharge produce the backward flow when filter screen or filter bag are fully blockked up appears.

Therefore, the filter screen or the filter bag is required to be subjected to ash removal treatment, wherein ash removal is an important link in the operation of the dust remover, the efficiency, the pressure loss, the filtering speed, the service life of the filter bag and the like of the dust remover are all related to ash removal modes, and the simple ash removal is realized by adopting manual periodic beating or shaking of a manual control mechanism, so that the manual ash removal efficiency is lower; the mechanical ash removal is that the filter bag is vibrated by a mechanical vibrating mechanism to fall into the ash bucket, and the mechanical ash removal easily causes the filter bag or the filter screen to be damaged quickly under the action of mechanical force; the air flow ash removing method uses back blowing air to pass through the filter bag and the dust layer from opposite directions, so that dust falls off from the filter bag, but the air flow ash removing device has complex structure and high cost.

For example, the patent publication number is CN113713514B, the patent name is self-cleaning anti-blocking smoke detection device, the technical scheme discloses a smoke detector and a filter connected with the smoke detector, the filter comprises a box body and supporting legs arranged at the bottom of the box body, a smoke inlet and a smoke outlet are arranged on the box body, a first smoke pipe is arranged between the smoke detector and the box body, a base is rotationally connected in the box body and driven by a servo motor, a cylindrical screen with sieve holes at the periphery is embedded on the base, a second smoke pipe corresponding to the first smoke pipe is arranged on the box body, an opening is arranged at the upper end of the box body, a first upper cover is arranged at the opening, a smoke flow rate meter is arranged in the box body and fixedly connected at the smoke outlet of the box body, the outer wall of the box body is connected with the controller, the flue gas flow rate meter is electrically connected with the controller, the controller is electrically connected with the servo motor, the technical scheme is that the flue gas flow rate is monitored, when the cylindrical screen in the box body is blocked, the cylindrical screen can be driven to rotate under the mutual cooperation of the flue gas flow rate meter, the controller and the servo motor, so that the blocked part of the surface of the cylindrical screen is not opposite to a flue inlet, the normal circulation of flue gas in the box body is ensured, but after the cylindrical screen is used for a long time, the surface of the cylindrical screen is basically blocked when the cylindrical screen is rotated for 180 degrees, the continuous filtration of the flue gas can be maintained only by cleaning or replacing the screen, the popularization and the application are not facilitated, and the continuous filtration effect of the flue gas can be achieved only by solving the problem of the screen blocking.
