Description

Technical Field

[0001] The utility model relates to the technical field of gas turbine power plants, in particular to a safety ventilation device for gas turbine power plants. Background Art

[0002] A gas turbine power plant is a place that uses the heat generated by gas combustion to generate electricity. It is one of the main forms of thermal power generation. The main equipment used includes gas turbines, generators, waste heat boilers and steam turbines. Since a high concentration of gas in the air can cause serious danger, a safety ventilation device is needed to ventilate the plant. In order to ensure the freshness of the air inside the plant, filters are usually installed at the vents to filter dust. Dust accumulation on the filter will affect the air flow of the filter, so the filter needs to be cleaned. However, the current safety ventilation device for gas turbine power plants is not easy to clean the filter, which can easily cause impurities to accumulate on the filter, reducing the air flow and affecting the air flow inside the plant. At the same time, since using a brush to clean the filter can easily cause the brush and filter to wear, the brush and filter need to be replaced and maintained in time. However, the current safety ventilation device for gas turbine power plants is not convenient for replacing and maintaining the brush and filter, which can easily cause the brush and filter to wear during use, reducing the cleaning effect of the brush and the filtering effect of the filter.

[0003] To solve the above problems, the existing technology patent (CN216481435U) discloses a safety ventilation device for a gas turbine power plant, comprising a blowing pipe, a right-angled air duct, a multi-stage guide vane, a double-headed motor and a dust filter. The end bolts of the blowing pipe are installed with a right-angled air duct, and the interior of the right-angled air duct is embedded with a multi-stage guide vane, and the interior of the blowing pipe is installed with a double-headed motor.

The safety ventilation device for a gas turbine power plant is convenient for cleaning the filter screen, avoiding the accumulation of impurities on the filter screen and reducing the ventilation volume. At the same time, the ventilation device is convenient for replacing and maintaining brushes and filters, avoiding wear of the brushes and filters during use, reducing the cleaning effect of the brush and the filtering effect of the filter screen.

[0004] However, in the above-mentioned prior art, maintenance personnel are required to regularly replace the ventilation filter and brushes. During the replacement, the ventilation device cannot operate, which increases maintenance costs and limitations. Utility Model Content
