Description

Technical Field

[0001] The utility model relates to the technical field of ventilation of thermal power plants, in particular to a ventilation structure of a thermal power plant. Background Art

[0002] A thermal power plant, also known as a thermal power plant, uses combustible materials (such as coal) as fuel to produce electricity. The basic production process is as follows: Combustion of the fuel heats water to generate steam, converting the fuel's chemical energy into thermal energy. The steam pressure then drives a turbine, converting the thermal energy into mechanical energy. The turbine then drives a generator, converting the mechanical energy into electrical energy. To maintain a consistent temperature in the workplace, thermal power plants require adequate ventilation to prevent poor air quality from affecting worker health.

[0003] After searching, the existing Chinese patent with publication number CN202220534330.9 discloses a ventilation and heat dissipation device for a thermal power plant, wherein an air inlet device is detachably installed at one end of the thermal power plant room, a side exhaust device is detachably installed at the other end of the thermal power plant room, and a top heat dissipation device is detachably installed at the top of the thermal power plant room. The air entering through the air inlet device is discharged through the side exhaust device and the top heat dissipation device, thereby accelerating the air circulation inside the thermal power plant room. At the same time, according to the principles of aeronautics, the hot air is discharged from the top, which lowers the indoor temperature, reduces the aging speed of the machine, and makes the interior of the thermal power plant room more comfortable; the rotating shaft is movably installed inside the rotating hole, and the spring assembly is movably installed on the side of the movable groove. The filter device is simple to disassemble and install, and is convenient to use, thereby protecting the internal environment of the thermal power plant room and the health of the staff. It is easy to clean and more convenient to use.

[0004] The above technical solution has the following defects: although such a thermal power plant ventilation structure can accelerate the air circulation in the thermal power plant through the exhaust component, thereby providing the ventilation capacity of the thermal power plant and protecting the working environment, when the ventilation structure of the thermal power plant is maintained and repaired, the ventilation component needs to be closed, affecting the normal operation of the thermal power plant. For this reason, a thermal power plant ventilation structure is first proposed, which is provided with a filter component that is convenient for handling dust. When the dust filtered in the ventilation structure needs to be cleaned, the ventilation structure does not need to be closed, and the ventilation needs of the thermal power plant will not be affected.

[0005] In view of this, the author improves and solves the above problems, concentrates on research and combines theoretical application, and finally proposes a technical solution with reasonable design and effective improvement of the above defects.

[0006] The information disclosed in this background technology section is only intended to deepen the understanding of the overall background technology of the present invention, and should not be regarded as an admission or any form of suggestion that the information constitutes the prior art already known to those skilled in the art. Utility Model Content

[0007] The utility model provides a ventilation structure for a thermal power plant, which solves the problems raised in the above background. A filtering component is provided for facilitating dust processing. When dust filtered in the ventilation structure needs to be cleaned, the ventilation structure does not need to be closed, and the ventilation needs of the thermal power plant will not be affected.

[0008] The solution of the utility model to solve the above technical problems is as follows: a thermal power plant ventilation structure, comprising a thermal power plant wall, a ventilation duct, and a ventilation fan, the ventilation duct runs through the thermal power plant wall, the ventilation duct is fixedly connected with a U-shaped tube, the U-shaped tube is fixedly connected with a dust collecting box, the dust collecting box is fixedly installed with a dust collecting hopper, the dust collecting box is fixedly installed with a slot fixedly installed inside the dust collecting box, the slot is slidably connected with a sealing plate, the bottom end of the dust collecting box is fixedly connected with a drain valve, the interior of the ventilation duct is fixedly installed with a partition plate, the U-shaped tube is fixedly installed with a mounting plate, the mounting plate is evenly installed with a filter bag frame and a dust collection filter bag, the U-shaped tube is fixedly installed with a spray pipe, the spray pipe is evenly fixedly connected with a nozzle corresponding to the dust collection filter bag, the spray pipe is fixedly connected with a pulse valve, the pulse valve is fixedly connected with an air bag, the ventilation duct is installed with a limiting frame corresponding to the ventilation fan, the ventilation fan can be inserted into the limiting frame, and the ventilation fan is connected to the ventilation duct by screws.

[0009] On the basis of the above technical solution, the present invention can also be improved as follows.

[0010] Furthermore, the sealing plate can be connected to the dust box by screws.

[0011] Furthermore, the bottom end of the dust collecting box is configured as a conical structure.

[0012] Furthermore, two partition plates are provided, and the two partition plates are respectively provided at both ends of the U-shaped tube.

[0013] Furthermore, protective nets are installed at both ends of the ventilation duct through bolts.

[0014] Furthermore, the U-shaped tube is provided with a mounting hole corresponding to the blowing tube, and the interior of the mounting hole is fixedly connected to the blowing tube, and the connection is sealed.

[0015] Furthermore, the ventilation duct is provided with a socket corresponding to the ventilation fan.

[0016] The utility model provides a ventilation structure for a thermal power plant, which has the following advantages:

[0017] 1. The air inside the wall of the thermal power plant is drawn into the ventilation duct from one side and transferred to the U-shaped tube under the separation effect of the partition plate. The dust filter bag at the installation plate can intercept the smoke and dust in the air, and act as a pulse valve to spray the gas in the air bag through the nozzle of the blowing pipe. The filter bag frame can limit the dust filter bag, so that the dust can be blown down by the air flow and collected in the dust collecting hopper, thereby preventing the smoke and dust from clogging the dust filter bag and affecting the ventilation effect.

[0018] 2. The filtered air can be discharged from the other end of the ventilation duct. The dust collected in the dust hopper passes through the slot and is collected in the dust box. When the dust needs to be cleaned, the slot can be driven to slide and seal the dust hopper at the sealing plate. The drain valve can be opened to uniformly process the smoke and dust collected in the dust box. Since it is isolated from the ventilation duct and U-shaped tube, it will not affect the normal ventilation operation.

[0019] 3. Such a thermal power plant ventilation structure is provided with a filter assembly for facilitating dust treatment. When the dust filtered in the ventilation structure needs to be cleaned, the ventilation structure does not need to be closed, which will not affect the ventilation needs of the thermal power plant.
