Description

Technical Field

[0001] The utility model belongs to the technical field of power generation smoke filtering, and in particular relates to a power generation smoke filtering device. Background Art

[0002] During the operation of existing power generation flue gas bag filter, the high temperature of flue gas will cause the filter bag material to age and wear, thus reducing its service life. In addition, dust particles in the flue gas will easily accumulate in the heat exchange structure pipeline, blocking the pipeline and affecting the normal circulation of flue gas. This not only reduces the efficiency of the dust collector, but also requires regular filtration and maintenance of high-temperature flue gas, thereby increasing the operating cost of the power plant. Utility Model Content

[0003] In order to overcome the problem of high maintenance cost of high temperature flue gas filtration, the existing power generation flue gas bag filter has high service life of the filter bags due to the high temperature of the flue gas and the flue gas heat exchange structure pipelines are easily clogged by ash.

The flue gas is then discharged after being filtered for dust through a pulse bag dust collector. The straight pipe ventilation structure of the corrosion-resistant and high-temperature heat exchange air pipe effectively reduces wind resistance and prevents dust adhesion, while the dust exhaust vibration motor drives the funnel-shaped air collecting hood to vibrate at high frequency to realize the external discharge function of the attached dust, which solves the problem of existing power generation flue gas bag dust collectors, because the high temperature of the flue gas can easily reduce the service life of the filter bag, and the flue gas heat exchange structure pipelines are prone to ash accumulation and clogging, resulting in high maintenance costs for high-temperature flue gas filtration.

[0006] Preferably, the flue gas cooling assembly includes a cooling and heat exchange shell, a ventilation joint, an inlet and outlet water pipe, a corrosion-resistant and high-temperature resistant heat exchange air pipe, a heat exchange air pipe base, an air pipe bracket, an air collecting hole, a funnel-shaped air collecting hood, and a dust exhaust vibration motor; ventilation joints are provided at both ends of the cooling and heat exchange shell, and the ventilation joints are sealed and connected to the cooling and heat exchange shell flange.

The straight pipe ventilation structure of the corrosion-resistant and high-temperature heat-exchange air pipe effectively reduces wind resistance and prevents dust adhesion, and the dust exhaust vibration motor drives the funnel-shaped air collecting hood to vibrate at high frequency to realize the external discharge function of the attached dust.

[0009] Preferably, an air collecting hole is provided through the inside of the ventilation joint; a funnel-shaped air collecting hood is provided at one inner end of the ventilation joint, and the funnel-shaped air collecting hood is integrally formed with the ventilation joint, and the funnel-shaped air collecting hood is used to collect airflow and prevent dust adhesion as much as possible.

[0010] Preferably, a dust removal vibration motor is provided between the funnel-shaped air collecting hood and the ventilation joint, and the housing of the dust removal vibration motor is fixedly connected to the outer end surface of the funnel-shaped air collecting hood.

[0011] Preferably, the clean air output end of the pulse bag dust collector is connected to the input end pipeline of the high-speed exhaust fan.

[0022] See also Figure 1-4 In this embodiment, the flue gas cooling component 1 includes a cooling and heat exchange shell 101, a ventilation joint 102, an inlet and outlet water pipe 103, a corrosion-resistant and high-temperature resistant heat exchange air pipe 104, a heat exchange air pipe base 105, an air pipe bracket 106, an air collecting hole 107, a funnel-shaped air collecting hood 108, and a dust exhaust vibration motor 109; ventilation joints 102 are provided at both ends of the cooling and heat exchange shell 101, and the ventilation joints 102 are flange-sealed to the cooling and heat exchange shell 101.

[0023] See also Figure 1-4 In this embodiment, a corrosion-resistant and high-temperature heat-exchange air pipe 104 is arranged inside the cooling and heat-exchange shell 101; heat-exchange air pipe bases 105 are arranged at both ends of the corrosion-resistant and high-temperature heat-exchange air pipe 104, and the vent holes of the heat-exchange air pipe base 105 are sealed and fixedly connected to the corrosion-resistant and high-temperature heat-exchange air pipe 104, and the heat-exchange air pipe base 105 is sealed and fixedly connected to the cooling and heat-exchange shell 101 and the vent joint 102, and an air pipe bracket 106 is arranged on the outside of the corrosion-resistant and high-temperature heat-exchange air pipe 104, and the air pipe bracket 106 is sleeve-connected to the corrosion-resistant and high-temperature heat-exchange air pipe 104, and The air pipe bracket 106 is fixedly connected to the inner wall of the cooling and heat exchange shell 101, and an air collecting hole 107 is provided inside the ventilation joint 102; a funnel-shaped air collecting hood 108 is provided at the inner end of the ventilation joint 102, and the funnel-shaped air collecting hood 108 and the ventilation joint 102 are integrally formed, a dust removal vibration motor 109 is provided between the funnel-shaped air collecting hood 108 and the ventilation joint 102, and the outer shell of the dust removal vibration motor 109 is fixedly connected to the outer end face of the funnel-shaped air collecting hood 108, and the clean air output end of the pulse bag dust collector 2 is connected to the input end pipeline of the high-speed exhaust fan 3.

[0024] During operation, the high-temperature flue gas passing through the internal part is absorbed by the corrosion-resistant and high-temperature heat exchange air pipe 104, and the heat exchange is carried out in conjunction with the water flow in and out of the water inlet and outlet pipes 103 to reduce the flue gas temperature. After that, the flue gas is discharged after the smoke is filtered through the pulse bag dust collector 2. The straight pipe ventilation structure of the corrosion-resistant and high-temperature heat exchange air pipe 104 effectively reduces the wind resistance and prevents the adhesion of dust, and the dust exhaust vibration motor 109 drives the funnel-shaped air collecting hood 108 to vibrate at a high frequency to realize the external discharge function of the attached dust.

[0025] Next, the heat exchange air pipe base 105 effectively improves the structural connection stability and air tightness between the corrosion-resistant and high-temperature-resistant heat exchange air pipe 104 and the ventilation joint 102, preventing the leakage of smoke and moisture.

[0026] Through the above steps, the corrosion-resistant and high-temperature heat exchange air pipe 104 absorbs heat from the high-temperature flue gas passing inside, and the water flow in and out of the inlet and outlet water pipe 103 is used to exchange heat to reduce the flue gas temperature. The flue gas is then discharged after being filtered for dust through the pulse bag dust collector 2. The straight pipe ventilation structure of the corrosion-resistant and high-temperature heat exchange air pipe 104 effectively reduces wind resistance and prevents dust adhesion, while the dust exhaust vibration motor 109 drives the funnel-shaped air collecting hood 108 to vibrate at high frequency to achieve the external discharge function of the attached dust, thus avoiding the problem of high maintenance cost of high-temperature flue gas filtration caused by the existing power generation flue gas bag dust collector, because the high temperature of the flue gas can easily reduce the service life of the filter bag, and the flue gas heat exchange structure pipeline is prone to ash accumulation and clogging.
