Abstract
Description
Technical Field
[0001] This utility model belongs to the field of flue gas emission technology, and in particular relates to a flue gas emission pipeline structure for an electrostatic precipitator. Background Technology
[0002] Electrostatic precipitators (ESPs) generate large amounts of flue gas during processes such as asphalt unloading. If these gases are not effectively collected and treated, they will permeate the production site, severely impacting the working environment and employee health, while also posing environmental compliance risks. Traditional ESPs typically have built-in fans for flue gas emission, but these suffer from high energy consumption, high operating noise, and high maintenance costs. Especially during unloading, flue gas is prone to unorganized dispersion, and current technologies lack an energy-efficient and comprehensive flue gas extraction solution. Therefore, there is an urgent need for an ESP flue gas emission system that is structurally sound, economically operated, and can completely solve the problem of flue gas overflow.

[0012] Preferably, the flue gas diversion pipe is fixed to the pipe support frame by pipe clamps.
[0013] Preferably, the structure utilizes the negative pressure of the black dust removal system as a power source to draw all the flue gas generated by the electrostatic precipitator into the black dust removal system for purification.
[0014] Compared with related technologies, the flue gas emission pipe structure of the electrostatic precipitator provided by this utility model has the following beneficial effects: 1.

[0022] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.
[0023] A preferred embodiment of the flue gas emission pipe structure of the electrostatic precipitator provided by this utility model is, for example... Figures 1 to 2 As shown: A flue gas emission duct structure for an electrostatic precipitator, comprising: Electrostatic precipitator 1; Black dust removal system 2, which has a negative pressure source; The flue gas diversion pipe 3 has one end connected to the flue gas outlet of the electrostatic precipitator 1 via a flexible connection 4, and the other end connected to the inlet of the black dust removal system 2. One or more pipe support frames 5 are used to support and fix the flue gas diversion pipe 3.
[0024] The diameter of flue gas diversion pipe 3 is 400mm.
[0025] Flexible connector 4 is made of flexible non-metallic material and is used to compensate for vibration and displacement between pipes.
[0026] The pipe support frame 5 is made of welded I-beams.
[0027] The bottom of the pipe support frame 5 is provided with a concrete base 6.
[0028] The inlet of the black dust removal system 2 is connected to the upper part of its settling chamber 21.
[0029] The original induced draft fan of the electrostatic tar precipitator 1 stopped operating after the flue gas diversion pipe 3 was connected.
[0030] The total length of flue gas diversion pipe 3 is approximately 70 meters.
[0031] The flue gas diversion pipe 3 is fixed to the pipe support frame 5 by pipe clamps 7.
[0032] This structure utilizes the negative pressure of the black dust removal system 2 as a power source to guide all the flue gas generated by the electrostatic precipitator 1 to the black dust removal system 2 for purification.
[0033] The working principle and process of this utility model are as follows: The flue gas generated by the electrostatic precipitator 1 during processes such as asphalt unloading was originally driven by its own induced draft fan. After modification, its flue gas outlet is connected to the inlet of the settling chamber 21 of the black dust removal system 2 via a flue gas diversion pipe 3. The key is that this utility model creatively utilizes the strong negative pressure generated by the black dust removal system 2 itself during operation as a new power source. This negative pressure is transmitted to the flue gas outlet of the electrostatic precipitator 1 through the flue gas diversion pipe 3, forming a suction force, thus replacing the original induced draft fan. Under the action of negative pressure, the flue gas flows sequentially through the flexible connection 4 and the flue gas diversion pipe 3, and is finally completely drawn into the black dust removal system 2 for efficient purification treatment, achieving emission standards.
[0034] In practical implementation, a site survey and design were first conducted to determine the pipeline laying path and support points. A pipeline support frame 5 was fabricated using scrap I-beams, and a foundation pit was excavated at its base, with a concrete base 6 poured to ensure long-term stability. A 400mm diameter pipe, approximately 70 meters long, was selected as the flue gas diversion pipe 3 and laid along the designed path on the support frame 5. One end of the pipe was reliably connected to the fan interface of the electrostatic precipitator 1 via a flexible non-metallic connector 4. This design effectively compensates for displacement caused by equipment vibration and prevents pipe stress damage. The other end was connected to the inlet at the top of the settling chamber 21 of the black dust removal system 2. The entire pipeline was securely fixed to the support frame 5 using pipe clamps 7. After the system connection was completed, commissioning was performed: the black dust removal system 2 was started, using its negative pressure to draw in the flue gas from the electrostatic precipitator 1, while simultaneously stopping the operation of the original induced draft fan of the electrostatic precipitator 1. During commissioning, the smoothness of the flue gas flow and the overall system sealing were monitored to ensure no flue gas leakage.
[0035] Compared with related technologies, this specific implementation method achieves the following significant beneficial effects through structural modifications: First, it completely eliminates the unorganized spread of flue gas during the unloading of asphalt by the electrostatic precipitator, fundamentally improving the production site environment and protecting employee health; Second, it fully utilizes the surplus negative pressure capacity of the existing black dust removal system, discontinuing the original 30kW induced draft fan of the electrostatic precipitator, saving over 110,000 yuan in electricity costs annually, resulting in significant energy-saving and consumption-reducing benefits; Third, the flue gas is entirely introduced into a mature dust removal system for treatment, ensuring that emission indicators consistently meet environmental protection requirements and mitigating environmental risks; Fourth, the pipeline support structure is robust, the flexible connection design is reasonable, the system operates reliably, and maintenance workload is minimal.
