Description

Technical Field

[0001] The invention belongs to the technical field of bag dust removal, and in particular relates to a dust removal bag cooling device. Background Art

[0002] The material of the dust collector bag is cloth or felt woven from synthetic fiber, natural fiber or glass fiber. The cloth or felt is sewn into cylindrical or flat filter bags according to the needs. According to the properties of the flue gas, the filter material suitable for the application conditions is selected. There are many kinds of materials for dust collector bags, and different materials are suitable for different working environments and dust removal requirements.

[0003] The differences in the materials of some dust collector bags are as follows: Polyester fiber bag: It has good heat resistance and chemical resistance, high filtration efficiency, and can filter out particles with a diameter of more than 1 micron. It is suitable for dust removal in harsh environments such as high temperature, high humidity, and high pH.

[0004] Polypropylene fiber bag: low price, good acid and alkali resistance and wear resistance, high filtration efficiency, can filter out particles with a diameter of more than 5 microns, suitable for dust removal in general industrial environments.

[0005] Fiberglass bag: resistant to high temperature and corrosion, it is a special dust bag material.

[0006] Polytetrafluoroethylene fiber cloth bag: high temperature resistant, corrosion resistant, with good heat resistance and chemical resistance.

[0007] Polyamide fiber bag: high temperature resistant, corrosion resistant, with good heat resistance and chemical resistance, and high filtration efficiency.

[0008] The existing dust bags are combined with production materials to improve high temperature resistance. The dust bags are installed in dust bag equipment to filter air particles. The gas in industrial scenes is often high-temperature gas, with a temperature of 300 to 500 degrees. Improving the high temperature resistance of the material alone leads to high costs and too high replacement frequency, resulting in high operating costs.

[0009] Therefore, in order to solve the problem of high cost and too frequent replacement of high-temperature dust bags in existing industrial dust removal technology. In industrial scenarios, especially those places where high-temperature gases are generated, such as steelmaking and chemical plants, particulate matter in the air needs to be filtered through high-temperature resistant dust bags. However, these high-temperature bags have high material requirements, which leads to increased costs, and due to the wear and damage of the bags in high-temperature environments, the replacement frequency also increases, further increasing the operating cost. A dust bag cooling device is proposed. Summary of the invention

[0010] The present invention aims to solve the technical problem that the high-temperature cloth bags in the above-mentioned prior art are relatively expensive and easily worn and damaged in a high-temperature environment, resulting in frequent replacement, thereby increasing operating costs.

[0011] To achieve the above object, the present invention provides the following technical solutions: A dust bag cooling device comprises a water chamber, an air inlet chamber and an air outlet chamber, wherein the water chamber is evenly arranged with integrated fine pipes which penetrate the water chamber and are composed of a plurality of fine pipes; the air inlet chamber and the air outlet chamber are respectively located on the left and right sides of the water chamber, and the air inlet chamber is connected to the air inlet of the integrated fine pipe, and the air outlet chamber is connected to the air outlet of the integrated fine pipe; When high-temperature air enters the integrated fine pipe through the air inlet chamber, it is divided into several fine pipes by the integrated fine pipe and is cooled by heat exchange with the water in the water chamber before being discharged through the air outlet chamber.

[0012] When the high-temperature air enters the integrated fine pipe from the air inlet chamber, it is divided into several fine pipes by the integrated fine pipe, subdividing the number of high-temperature air, increasing the area of ​​high-temperature air contacting water, and the water chamber is connected to the cooling tower to quickly cool the water in the water chamber, thereby achieving rapid cooling, and then enters the dust bag device from the outlet pipe for filtration. Among them, the higher the height of the integrated fine pipe submerged by the water in the water chamber, the faster the cooling speed. By increasing the contact area between the hot air and the water in the water chamber, the high-temperature air is quickly cooled. After cooling, the requirements for the high-temperature resistance of the dust bag are reduced, thereby reducing costs.

[0013] Preferably, an air inlet nozzle is provided at the top of the air inlet chamber, and the air inlet nozzle is connected to the high-temperature air inlet duct, which helps to centrally introduce high-temperature air and effectively distribute it to the integrated fine ducts, which helps to improve the uniformity of air distribution, thereby improving cooling efficiency and dust removal effect.

[0014] Preferably, an air outlet nozzle is provided on the top of the air outlet chamber, and the air outlet nozzle is connected to the dust bag device through a pipeline, which helps to introduce the air cooled by the water chamber into the dust bag device, and then be discharged after being filtered by the dust bag device, so as to ensure that the dust-removed air can be effectively purified and released into the external environment.

[0015] Preferably, the water chamber is connected to a cooling tower for rapidly cooling the water in the water chamber.

[0016] The water chamber is connected to the cooling tower, which helps to quickly cool down the water in the water chamber. It can improve the cooling efficiency, allowing the water to quickly absorb the heat of the high-temperature air, thereby speeding up the cooling process and improving the overall heat exchange efficiency.

[0017] Preferably, one side of the bottom of the air inlet chamber and the air outlet chamber is provided with an inspection port, and a detachable inspection cover is threadedly connected to the inspection port.

[0018] It is convenient to maintain and overhaul the device, reducing the need to open the entire device and improving the convenience and safety of maintenance.

[0019] Preferably, the water chamber is a rectangular box structure.

[0020] This helps provide greater water capacity, thereby enhancing cooling capabilities, while the rectangular structure may be easier to manufacture and install.

[0021] Preferably, the number of integrated thin pipes can be increased so that the high-temperature air can be divided from 1 part to 100 parts, or from 1 part to 200 parts.

[0022] Integrated fine ducts can increase the number of groups and divide the high-temperature air into more fine airflows. This design helps to further increase the contact area between the high-temperature air and water, improve cooling efficiency, and may also help to increase the service life of the dust bag, because finer airflow can reduce wear on the bag.

[0023] Compared with the prior art, the technical effects and advantages of the present invention are: The dust bag cooling device distributes the high-temperature air into multiple fine pipes through the design of integrated fine pipes, thereby increasing the contact area between air and water and using water cooling to achieve rapid cooling of the high-temperature air. This design effectively reduces the high temperature entering the dust bag, thereby allowing the use of lower-cost materials with poorer high-temperature resistance, reducing the demand for special high-temperature resistant materials and reducing the cost of dust bags. At the same time, due to the good cooling effect, the high-temperature resistance requirements of the bags are reduced, thereby reducing the replacement frequency and reducing operating costs.

[0024] Water cooling is used to reduce the high temperature gas entering the dust bag, thereby reducing the need for special high temperature resistant materials and reducing costs. In addition, the cooling device can extend the service life of the bag and reduce the frequency of replacement, thereby reducing the overall operating cost. This cooling device is designed to improve the efficiency of industrial dust removal while reducing maintenance costs, achieving air pollution control in a more economical and efficient way.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] The following is combined with Figure 1-4 To further explain this application in detail, The embodiment of the present application discloses a dust bag cooling device, comprising a water chamber 1, an air inlet chamber 3 and an air outlet chamber 4. The water chamber 1 is a rectangular box structure, and the water chamber 1 is evenly arranged with integrated fine pipes 2 which penetrate the water chamber 1 and are composed of a plurality of fine pipes; the air inlet chamber 3 and the air outlet chamber 4 are respectively located on the left and right sides of the water chamber 1, and the air inlet chamber 3 is connected to the air inlet 10 of the integrated fine pipe 2, and the air outlet chamber 4 is connected to the air outlet 11 of the integrated fine pipe 2; When high-temperature air enters the integrated fine pipe 2 through the air inlet chamber 3 , it is divided into a plurality of fine pipes by the integrated fine pipe 2 and is cooled by heat exchange with the water in the water chamber 1 before being discharged through the air outlet chamber 4 .

[0029] An air inlet nozzle 5 is provided at the top of the air inlet chamber 3, and the air inlet nozzle 5 is connected to the high-temperature air inlet pipe. An air outlet nozzle 6 is provided at the top of the air outlet chamber 4, and the air outlet nozzle 6 is connected to the dust bag device 7 through a pipeline. The water chamber 1 is connected to a cooling tower 8 for rapidly cooling the water in the water chamber 1.

[0030] The dust bag cooling device uses a water cooling system to reduce the high temperature gas entering the dust bag, thereby reducing the demand for special high temperature resistant materials and extending the service life of the bag.

[0031] The water chamber 1 adopts a rectangular box structure, and the integrated fine pipes 2 are evenly arranged inside and run through it. These fine pipes are composed of several pipes. After the high-temperature air enters the integrated fine pipe 2 through the air inlet chamber 3, it will be distributed to multiple fine pipes and exchange heat with the water in the water chamber 1 for cooling. The air inlet chamber 3 and the air outlet chamber 4 are respectively located on the left and right sides of the water chamber 1. The air inlet chamber 3 is connected to the air inlet 10 of the integrated fine pipe 2, and the air outlet chamber 4 is connected to the air outlet 11 of the integrated fine pipe 2. Such a layout helps to centrally introduce high-temperature air and effectively distribute it to the integrated fine pipe 2, thereby improving the cooling efficiency. The water chamber 1 is connected to the cooling tower 8, which helps to quickly cool down the water in the water chamber 1. The cooling tower 8 quickly cools down the water through the principle of evaporative cooling, so that the water can quickly absorb the heat of the high-temperature air, thereby accelerating the cooling process.

[0032] By exchanging heat between high-temperature air and water, the air temperature can be effectively reduced and the cooling efficiency can be improved. Since the temperature of the gas entering the dust bag is reduced, the demand for special high-temperature resistant materials can be reduced, thereby reducing material costs. Lowering the temperature helps reduce wear and damage to the bag, thereby extending the service life of the bag. By cooling, the filtering efficiency and performance of the dust bag can be improved, thereby improving the dust removal effect.

[0033] An inspection port 9 is provided at one side of the bottom of the air inlet chamber 3 and the air outlet chamber 4, and a detachable inspection cover is threadedly connected to the inspection port 9. This facilitates maintenance and overhaul of the device, reduces the need to open the entire device, and improves the convenience and safety of maintenance.

[0034] The number of integrated thin pipes 2 can also be increased, so that the high-temperature air can be divided from 1 to 100 parts, or from 1 to 200 parts. The number of integrated thin pipes 2 can be increased to divide the high-temperature air into more fine airflows. This design helps to further increase the contact area between the high-temperature air and the water, improve the cooling efficiency, and may also help to increase the service life of the dust bag, because the finer airflow can reduce the wear on the bag.

[0035] The dust bag cooling device uses a cooling system to reduce the high-temperature gas entering the dust bag, reduces the need for special high-temperature resistant materials, and extends the service life of the bag, thereby reducing overall operating costs.

[0036] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein.
