Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of flue gas purification, in particular to a flue gas purification device. Background Art
[0002] Most of the existing fire-burning drying rooms will produce a large amount of dirty smoke, which is discharged outward through the chimney. This fire-insulated heat transfer mode often has low thermal efficiency, and a lot of heat cannot be converted and is forced to be discharged, resulting in waste and uneconomical. Some drying rooms adopt a smokeless burner design, supplemented by cyclone dust removal and purification technology, and the smoke is directly discharged into the drying room. Although it is clean and dust-free on the surface, because the smoke dust is too fine and too light, there is still a small amount of dust that cannot be completely purified and enters the drying room through the end of the cyclone purifier. It is okay for low cleanliness requirements, but for high requirements and high cleanliness of drying products, there is still a risk of not meeting the standards. Although it is energy-saving, it is useless if the cleanliness is not up to standard and it cannot work normally. At present, there are also devices for dust removal using water bodies. This device will cause the water body to absorb heat and evaporate a large amount of water, which will increase the humidity of the baking room, affecting the drying progress and work efficiency. Therefore, it is necessary to design a baking room with high cleanliness and low humidity. Utility Model Content
[0003] The purpose of the utility model is to provide a flue gas purification device in view of the shortcomings of the prior art. The device has a simple structure, low cost, convenient use and strong practicality.
[0004] The technical solution to achieve the purpose of this utility model is:
[0005] A flue gas purification device comprises a cyclone purifier and a liquid reservoir, wherein the outlet of the cyclone purifier is vertically spaced above the liquid reservoir, a water outlet is provided on the top side wall of the liquid reservoir and connected to a water outlet pipe, a water inlet pipe connected to a water supply source is provided below the side wall of the liquid reservoir, and the water outlet pipe and the water inlet pipe penetrate the side wall of a baking room and extend outward.
[0006] The top of the liquid reservoir is designed to be open, and the diameter of the opening is larger than the outlet diameter of the cyclone purifier;
[0007] The liquid contained in the liquid reservoir is water or a solution having physical properties similar to water;
[0008] The liquid storage container is made of a heat-insulating material or a composite material with low thermal conductivity.
[0009] The water outlet of the liquid reservoir is arranged at the top edge of the liquid reservoir.
[0010] The smoke generated by the combustion of the furnace in the baking room is purified by the cyclone purifier connected to the chimney. Most of the dust is removed, and the fine dust that cannot be purified is blown to the water basin from the outlet of the cyclone purifier. The dust is adsorbed on the liquid in the water basin and then discharged out of the baking room through the outlet pipe along with the flowing liquid. The dust that cannot be removed automatically is precipitated and removed manually.
[0011] Since the water outlet of the liquid reservoir is arranged above the side wall of the water basin, the liquid reservoir above the water surface avoids the accidental inhalation of excessive heat to increase the water temperature and reduce water evaporation; a uniform amount of liquid is maintained in and out, so that the liquid in the water basin is exchanged, and the heat brought by the hot air discharged through the outlet of the cyclone purifier is reduced to increase the liquid surface temperature, avoid the liquid temperature in the liquid reservoir from rising and evaporating water vapor, and reduce the increase of humidity in the drying room; the heat insulation design of the liquid reservoir is also for the liquid in the liquid reservoir to heat up and produce water vapor in the high-temperature environment of the baking room. The three measures work together to minimize the temperature rise of the water body and reduce water evaporation, so as to reduce the humidity in the baking room, and do not increase the extra water in the drying room due to artificial water increase and dust removal in the drying room, and keep the normal water content of the drying room to maintain normal, quickly dry the items, and simultaneously improve the cleanliness of the drying room, so as to achieve the purpose of baking with high standards and high requirements. The design of the opening diameter of the liquid reservoir being larger than the outlet of the cyclone purifier is to capture the vertically facing downward dust continuously, and capture the positively escaping dust after the wind direction is blocked, so as to further expand the effect of dust removal and purification.
[0012] The design of the water outlet at the top protects the water basin material exposed to the water surface and minimizes the basin's absorption of heat. In addition, the slowness and limitations of the low thermal conductivity of air to water are also beneficial to reducing the generation of extra water vapor in the baking room in addition to the baked goods.
[0013] The device has a simple structure, low cost, and is easy to use. It can provide a high-cleanliness, low-humidity environment for the baking room and is highly practical. BRIEF DESCRIPTION OF THE DRAWINGS
[0014] Figure 1 Schematic diagram of the structure of the embodiment device.
[0015] In the figure, 1 is a water basin, 2 is a water inlet pipe, 3 is a water outlet pipe, 4 is a cyclone purifier outlet, 5 is a cyclone purifier induced draft fan, 6 is a cyclone purifier, 7 is a chimney, 8 is a stove, and 9 is a baking room. DETAILED DESCRIPTION
[0016] The content of the utility model is further explained below in conjunction with the drawings and embodiments, but the utility model is not limited thereto. Example
[0017] Reference Figure 1A flue gas purification device includes a cyclone purifier 6 and a water basin 1, wherein an outlet 4 of the cyclone purifier 6 is vertically spaced above the opening of the water basin 1, a water outlet pipe 3 is provided on the top side wall of the water basin 1, and a water inlet pipe 2 connected to a water supply source is provided below the side wall of the water basin 1, and the water outlet pipe 3 and the water inlet pipe 2 penetrate the side wall of the baking room 9 and extend outward;
[0018] The opening diameter of the water basin 1 is larger than the outlet diameter of the cyclone purifier 6;
[0019] The liquid contained in the water basin 1 is water or a solution having similar physical properties to water; in this example, the liquid contained in the water basin 1 is water;
[0020] The water basin 1 is made of a heat-insulating material or a composite material with a low thermal conductivity.
[0021] After the smoke generated by the combustion of the furnace in the baking room 9 is purified by the cyclone purifier 6 connected to the chimney 7, most of the dust is removed, and the fine dust that cannot be purified is blown to the water basin 1 through the cyclone purifier outlet 4. The dust is adsorbed on the water in the water basin 1 and then discharged out of the baking room 9 through the outlet pipe along with the flowing water. The dust that cannot be automatically removed is precipitated and removed manually.
[0022] The ability of the water basin to directly heat the water on one side of the air is inherently slow and weak. The conditions for the water to heat up are offset by the continuous increase in the amount of circulating water from the outside. Without efficient water heating conditions, the water always maintains low temperature and low volatility conditions. Due to the conditions of water in multiple movements in the drying room, the conditions for water to heat up and evaporate are extremely low. Only a small amount of water is needed to reduce the incorrect evaporation of water vapor. Therefore, low water consumption to achieve efficient dust removal is also an energy-saving method. The conditions are similar to traditional baking without water, but the purpose of adding water to safely enhance dust removal has been achieved.
