Description

Technical Field

[0001] This application applies to float glass production lines to improve and reduce glass defects caused by dilution air in the cooling section during the production process. Background Technology

[0002] In the float glass production process, the cooling section requires dilution air drawn from the machine room by fans for cooling. Dilution air is a crucial parameter in the melting furnace process, primarily used for temperature control of the molten glass in the cooling section after being drawn by fans. Its airflow directly affects the lateral temperature distribution of the molten glass; improper design or adjustment can lead to temperature deviations in the flow channels, causing defects such as corrugations or production difficulties. Simultaneously, the dilution air must be clean and dust-free; otherwise, glass defects are likely to occur. In existing technologies in float glass production, the cleanliness of the dilution air is generally controlled by bag filters and high-temperature electrostatic precipitators. Analysis of the accumulated material on the outside of existing dust collection systems shows that over 95% consists of airborne particles such as dust, willow catkins, and pollen.

[0003] Baghouse dust collectors: These use high-temperature resistant filter bags (such as fiberglass), achieving a filtration efficiency of up to 99.9%, and are suitable for handling diluted air with high dust concentrations. Their cleaning methods include pulse jet cleaning and mechanical vibration to prevent filter bag clogging.

[0004] Electrostatic precipitator: It uses an electric field to adsorb dust, and is especially suitable for handling fine particles with a particle size of less than 1μm.

[0005] The above two dust removal methods are complex to implement and costly. The cleanliness of the dilution air in the cooling section of the melting furnace is not very low, so the above dust removal methods are not suitable for the dust removal process of the dilution air. Utility Model Content

[0006] The purpose of this application is to address the shortcomings of the aforementioned background technology by providing a dilution air intake system for the cooling section, which requires only simple modifications to the dilution air fan room, is easy to implement, has good dust removal effect, and is low in cost.

[0007] To achieve the above-mentioned objectives, this application adopts the following technical solution: A cooling section dilution air inlet system is provided, the system comprising:

[0008] A dilution air fan room, wherein the dilution air is used to generate dilution air to cool the temperature inside the melting furnace;

[0009] A dilution air blower, which is connected to a dilution air blower room, is used to draw cold air from the dilution air blower room for furnace cooling.

[0010] An air intake filtration module is installed on one side of the dilution fan room to filter the incoming air. The air intake is drawn into the dilution fan room by the dilution fan, creating a negative pressure. Air flows into the dilution fan room from the side of the air intake filtration module. The air intake filtration module includes an air filter element and a first metal screen.

[0011] Furthermore, a second metal screen is provided at the connection between the dilution air blower and the dilution air blower room; the edges of the second metal screen are sealed with glass glue.

[0012] The cooling section includes a dilution air intake system, which comprises at least two dilution fans and forms several furnace cooling air ducts.

[0013] The cooling section includes a dilution air intake system, and the dilution air fan room is equipped with a cleaning device and a cleaning pool.

[0014] As a preferred embodiment of this application, the metal screen is a 20-mesh stainless steel screen.

[0015] This application has the following beneficial effects:

[0016] This application modifies the existing fan intake and space entrance by replacing all the air intake windows and fan inlets with 20-mesh stainless steel wire mesh and sealing them with glass glue. This enhances the airtightness of the dilution fan room and ensures multiple purifications of the air as it flows through. The modification is simple, low-cost, and has a good cleaning effect.

[0017] Installing mop sinks indoors for convenient cleaning and creating a cleanroom environment is of great significance for improving glass quality. Attached Figure Description

[0018] The present application will be further described below with reference to the accompanying drawings and embodiments:

[0020] In the diagram, 1-dilution fan room, 2-air filter element, 3-first metal screen, 4-dilution fan, 5-second metal screen, 6-air outlet, 7-cleaning pool. Detailed Implementation

[0021] The technical solutions of this application will be described in detail below with reference to the accompanying drawings. The technical solutions in the embodiments of this application will be further clearly and completely described. It should be noted that the described embodiments are only a part of the implementation cases of this application, and not all of the implementation cases. Based on the implementation cases in this application, all other implementation cases obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0022] like Figure 1 As shown, this application provides a cooling section dilution air intake system, which includes: a dilution fan chamber 4 1, wherein the dilution air is used to generate dilution air to cool the temperature inside the furnace; and a dilution air fan, wherein the dilution air fan is connected to the dilution fan chamber 4 1 and is used to draw cold air from the dilution fan chamber 4 1 for furnace cooling.

[0023] An air intake filtration module is installed on one side of the dilution fan 4 chamber 1 to filter the air intake of the dilution fan 4 chamber 1. The air intake filtration module is installed on one side of the dilution fan 4 chamber 1 to filter the air intake of the dilution fan 4 chamber 1. The air intake filtration module includes an air filter element 2 and a first metal screen 3.

[0024] The air intake system provided in this application is designed to meet the process requirements of furnace cooling. The air intake filtration module only includes a screen and air filter element 2. In the implementation of the scheme, the addition of a medium-efficiency filter layer (such as meltblown fabric or electrostatic electret filter material) was considered to form a three-stage filtration system: primary (metal screen) - medium-efficiency - high-efficiency. However, adding a medium-efficiency filter layer would significantly affect the ventilation flow rate and the furnace cooling effect. Therefore, using air filter element 2 and a metal screen as the first stage of filtration in the air intake system satisfies both the air volume and air cleanliness requirements.

[0025] Furthermore, a second metal screen 5 is provided at the connection between the dilution air blower and the dilution air blower 4 chamber 1; the edge of the second metal screen 5 is sealed with glass glue.

[0026] Adding a 20-mesh stainless steel wire mesh to the air intake window and sealing it with glass glue not only adds a second layer of filtration but also increases the airtightness of the dilution fan room 4, reducing the risk of air pollution in the machine room.

[0027] The cooling section dilution air intake system includes at least two dilution fans 4, forming several furnace cooling air ducts.

[0028] The cooling section includes a dilution air intake system. The dilution fan chamber 4 is equipped with a cleaning device and a cleaning pool 7. A mop sink is installed indoors for convenient cleaning, aiming to create a dust-free environment, which is crucial for improving glass quality.

[0029] In a preferred embodiment of this application, a 20-mesh stainless steel screen is used. After comparing various metal screens with different mesh counts, our company found that the 20-mesh stainless steel screen performs best.

[0030] After the renovation, defects on the glass surface were significantly reduced, the quality of float glass production was significantly improved, and the company's production efficiency was greatly increased.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of this application. Those skilled in the art should understand that this application is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this application. Various changes and modifications can be made to this application without departing from the spirit and scope thereof, and all such changes and modifications fall within the scope of this application as claimed. The scope of protection of this application is defined by the appended claims and their equivalents.
