Description

Technical Field

[0001] The present invention relates to the technical field of dust collectors, in particular to a dust collector for a power plant. Background Art

[0002] The core function of dust collectors in power plants is to control and reduce solid particulate matter in flue gases released during the combustion of coal and other fossil fuels. These dust collectors are crucial for environmental protection and human health because they effectively reduce the concentration of suspended particulate matter in the air, reducing the risk of respiratory diseases and curbing the exacerbation of acid rain and the greenhouse effect.

[0003] Currently, power plants widely use air-box pulse bag filters as the primary equipment for treating coal-fired flue gas. These filters hold a significant position in the industry due to their high dust removal capabilities. However, they also face challenges in practical application, particularly regarding dust accumulation in the flue gas ducts and at their connections to the equipment.

[0004] The operating principle of an airbox pulse bag dust collector is simple and highly effective: a fan draws dust-laden flue gas into the collector, where it is then filtered through filter bags, trapping dust particles. Clean flue gas is discharged from the other end of the filter bags. However, over time, dust gradually accumulates in the flue gas inlet duct. While some dust is flushed by the flue gas into the dust collector for disposal, some remains deposited within the duct. This deposited dust easily agglomerates in high temperature and high humidity, reducing the cross-sectional area of ​​the duct and hindering the smooth flow of flue gas.

[0005] Furthermore, problems with the design or installation of the connection between the smoke inlet duct and the dust removal equipment can also lead to dust accumulation. Gaps or loose joints often occur, allowing dust particles in the flue gas to accumulate and form clumps. These clumps not only affect the normal operation of the equipment but can also impair its sealing performance.

[0006] The accumulation and agglomeration of dust in the smoke inlet duct and equipment connections significantly increases the flow resistance of the smoke and reduces the smoke inlet efficiency. This not only weakens the dust removal effect of the dust collector, but also increases the energy consumption burden of the fan, which has a negative impact on the economic benefits of the entire power plant. Summary of the Invention

[0007] In view of the problems existing in the prior art, the present invention is proposed.

[0008] In order to solve the above technical problems, the present invention provides the following technical solutions: a power plant dust collector, comprising:

[0009] A support frame and a dust removal box mounted on the support frame; and

[0010] A dust collecting hopper provided on the end surface of the dust removal box; and

[0011] Two connecting pipes are distributed on the side wall of the dust removal box, and are respectively connected to the smoke inlet pipe and the exhaust pipe through the two connecting pipes;

[0012] The connection between the smoke inlet pipe and the connecting pipe is a docking port, a mounting bracket is installed on the upper end of the smoke inlet pipe, and a fan is connected to the mounting bracket, and the fan is connected to the smoke inlet pipe through the docking pipe.

[0013] As a preferred solution of the power plant dust collector described in the present invention, the fan blows in fresh air to drive the dust particles agglomerated at the interface into the dust removal box and increase the wind flow in the smoke inlet duct.

[0014] As a preferred solution of the power plant dust collector described in the present invention, a connecting cloth belt is inserted into the side wall opening of the docking pipe, and a cleaning cloth belt is connected to the lower end of the connecting cloth belt.

[0030] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0031] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0032] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive of other embodiments.

[0033] like Figure 1 - Figure 4 The figure shows an innovative power plant dust collector. The core component of this system is the support frame 1, which stably bears the weight of the entire dust removal system. A dust collection box 2 is carefully installed at its upper end, serving as the main battlefield of the dust removal process. A dust collection hopper 3 is cleverly placed below the dust collection box 2 to collect processed dust particles.

[0034] On the side wall of the dust removal box 2, two connecting pipes 6 are carefully arranged, which respectively play the role of a bridge to communicate with the smoke inlet pipe 4 and the exhaust pipe 5. The smoke inlet pipe 4, as the entrance of the smoke, is provided with a mounting frame 7 at its upper end, on which a fan 8 is firmly installed. The fan 8 is closely connected to the smoke inlet pipe 4 through the docking pipe 9. This design enables the fan 8 to blow in fresh air strongly, thereby not only driving the dust particles that may be agglomerated at the docking port 10 (i.e., the connection between the smoke inlet pipe 4 and the connecting pipe 6) to smoothly enter the dust removal box 2, but also significantly enhancing the wind flow inside the smoke inlet pipe 4, thereby improving the dust removal efficiency.

[0035] The side wall of the butt joint 9 is cleverly designed with an opening, and a connecting cloth belt 12 is inserted. The lower end of the connecting cloth belt 12 is connected to the cleaning cloth belt 11. When the fan 8 is working, the wind force it blows will drive the cleaning cloth belt 11 to cling to the inner wall of the butt joint 10, thereby achieving efficient cleaning of dust particles and further ensuring the dust removal effect.

[0036] The dust removal box 2 adopts an advanced air box pulse bag dust removal mechanism, which can efficiently remove and filter dust particles and smoothly discharge the filtered dust particles into the dust collecting hopper 3 to complete the collection of dust particles.

[0037] In order to ensure the smooth progress of the dust removal process, a through channel is designed between the two connecting pipes 6, and an inclined plate is installed in it to effectively close the channel and prevent the flue gas containing dust particles from accidentally entering the exhaust pipe 5.

[0038] The connection between the connecting pipe 6 and the smoke inlet pipe 4 or the exhaust pipe 5 is fixed with connecting flanges, bolts, nuts and other fasteners to ensure the firmness and sealing of the connection. At the same time, these joints are also equipped with high-temperature resistant sealing rings to cope with the working requirements of high-temperature environments.

[0039] The mounting frame 7 is firmly mounted on the smoke inlet duct 4 by bolts, and the fan 8 is fixed to the side wall of the mounting frame 7 by bolts. The fan 8 and the butt pipe 9 are also fixedly connected by connecting flanges, nuts and bolts to ensure the stable operation of the entire system.

[0040] The cleaning belt 11 and connecting belt 12 are integrated into one unit, simplifying the structure and improving reliability. A rubber seal is also installed at the connection between the connecting belt 12 and the butt-joint pipe 9 to prevent dust particle leakage and ensure a tight seal. This power plant dust collector, with its meticulous design, efficient dust removal capabilities, and reliable performance, has made a significant contribution to environmental protection in power plants.

[0041] Working process: Flue gas generated by the power plant is first introduced into the dust removal system through the smoke inlet duct 4. A mounting bracket 7 is provided at the upper end of the smoke inlet duct 4. A fan 8, securely mounted on the mounting bracket 7, begins operation, tightly connected to the smoke inlet duct 4 via a docking pipe 9, powerfully blowing in fresh air.

[0042] The wind from the fan 8 drives the cleaning cloth 11 to adhere closely to the inner wall of the docking port 10 (i.e., the connection between the smoke inlet duct 4 and the connecting duct 6). This design effectively removes dust particles that may have agglomerated, ensuring that they can enter the dust removal box 2 smoothly. At the same time, it enhances the wind flow inside the smoke inlet duct 4 and improves the dust removal efficiency.

[0043] The flue gas entering the dust removal box 2 is efficiently filtered by the advanced air box pulse bag dust removal mechanism inside. This mechanism ensures that dust particles are effectively intercepted and the filtered clean flue gas is further transmitted.

[0044] The dust particles processed by the dust removal mechanism are smoothly discharged into the dust collecting hopper 3. As a collection device, the dust collecting hopper 3 can effectively collect and store these dust particles for subsequent processing or transportation.

[0045] The clean flue gas that has passed through the dust removal and filtration is discharged to the external environment through the exhaust duct 5. An inclined plate is installed in the through-channel designed between the connecting ducts 6 to seal the channel, preventing the flue gas containing dust particles from accidentally entering the exhaust duct 5, ensuring that the discharged flue gas meets environmental standards.

[0046] The entire dust collector is securely supported by the support frame 1. The connecting pipes 6, flanges, bolts, nuts and other fasteners, as well as high-temperature resistant seals, ensure the stability and tightness of the system. Even in high-temperature environments, the system can maintain normal operation and dust removal effectiveness.

[0047] The integrated design of the cleaning belt 11 and the connecting belt 12 simplifies the structure and improves reliability. When the fan 8 is operating, the cleaning belt 11 automatically performs cleaning operations, reducing manual intervention and maintenance downtime. Furthermore, the rubber seal at the connection between the connecting belt 12 and the connecting pipe 9 effectively prevents dust particle leakage. Through its carefully designed structure and efficient dust removal mechanism, this power plant dust collector achieves effective dust removal and clean exhaust from power plant flue gas, providing significant support for the power plant's environmental protection efforts.

[0048] Finally, it should be pointed out that the methods and devices described in detail above are merely embodiments, and those skilled in the art can modify these embodiments in different ways without departing from the scope of the present invention.
