Description

Technical Field

[0001] The utility model relates to the technical field of waste gas filtering, in particular to a high-efficiency fiber filter system. Background Art

[0002] Waste gas refers to toxic and harmful gases emitted by humans during production and daily life. During the production of apparel fabrics, waste gas emissions primarily come from the production of chemical fibers, particularly viscose fibers. Chemical fiber production uses large amounts of carbon disulfide and hydrogen sulfide as synthetic raw materials, resulting in waste gas that primarily contains irritating gases, dust, and fibers.

[0003] If the filtration process continues, the pores in the filter layer are gradually filled with suspended solids, and the filtration resistance increases, making the filtration process no longer sustainable. In particular, the fibers in the residue continue to accumulate, and the fibers tend to aggregate and break, thereby deteriorating the performance of the fiber filter and making it difficult to clean later.

DETAILED DESCRIPTION

[0028] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0029] See attached Figure 1-6 As shown, the high-efficiency fiber filter system includes a filter base 1, one side of which is provided with an exhaust gas inlet 2 and the opposite far end is provided with an exhaust gas outlet 3. The filter base 1 is provided with two filter units, and there is a gap between adjacent filter units. The first part of the filter unit includes a vortex structure 4, a stratified flow control spray device 5 and a baffle 6 arranged upward along the exhaust gas flow direction for coarse filtration.

[0030] A wastewater outlet 10 is provided at the bottom of the filter base 1 .

[0031] Specifically, the structures of the vortex structure 4, the layered flow control spray device 5 and the baffle 6 are as follows.

[0032] The vortex structure 4 is a fixed vortex structure 4, which includes a vortex seat 41 with an annular groove. Diverter plates 42 are arranged at equal intervals in the circumferential direction of the annular groove. After the exhaust gas enters, it is dispersed by the vortex of the diverter plates 42, and the exhaust gas is rectified relatively evenly after passing through the vortex structure 4 from a chaotic flow direction. The diverter plates 42 are arranged at an angle to increase the spray contact area, and large particles will adhere to the blades and fall off.

[0033] The layered flow control spray device 5 is a device that uses six atomizing nozzles 9 placed above the vortex structure 4 and adapted to its circumferential position to spray water mist at 120 degrees inside the box at the same time, so that the water mist can spread throughout the interior of the spray box, which can effectively reduce the temperature of the exhaust gas and intercept large particle pollutants dispersed by the vortex.

[0034] The deflection assembly includes a horizontal array of deflectors 6, which are made of stainless steel. The exhaust gas rises and passes through the deflectors 6 to integrate the airflow. After being sprayed, tiny particles adhere and fall off to form secondary filtration, which can remove and filter most of the oil, water droplets, water mist, etc.

[0035] An exhaust gas flow channel 62 is formed between adjacent baffles 6, dividing the entire interior space. All baffles 6 are connected to the filter base 1 via brackets 61. The baffles 6 are vertically zigzag, consisting of multiple vertical and inclined plates that are staggered and stacked upward. When moistened exhaust gas enters the exhaust gas flow channel 62, it collides with the inclined baffles 6, blocking some large impurities in the exhaust gas and allowing them to seep downward along the baffles 6.

[0036] The blocking plate 7 is provided with a plurality of horizontally arranged ventilation grooves 71. The ventilation grooves 71 are arranged at intervals in the vertical direction, and the bottom thereof is hollowed out 72, so that most of the exhaust gas flows into the second part of the filter unit from the bottom, and a small part enters the second part of the filter unit through the ventilation grooves 71. Since the exhaust gas enters from the bottom of the blocking plate 7, it is basically filtered through the bottom of the annular filter element 8 first, causing its bottom to be contaminated first, and the subsequent exhaust gas still contacts the bottom of the annular filter element 8 first, which affects the filtration efficiency. The setting of the ventilation grooves 71 enables the exhaust gas to directly contact the entire annular filter element 8 in the vertical direction, thereby improving the exhaust gas filtration rate and slowing down the speed and degree of contamination of the bottom of the annular filter element 8 to a certain extent. The front and rear steam cleaning of the filter base 1 can quickly cause the oil and particulate matter condensed on the surface of the filter cotton to drip into the oil at the bottom of the filter base 1 along with the oleophobic filter cotton, and then be discharged through the wastewater outlet 10.

[0037] Secondly, there is a gap d between the blocking plate 7 and the first filter unit. The setting of the gap is mainly used to retain the exhaust gas so that more of it can flow out from the ventilation groove 71, avoiding the exhaust gas from being directly discharged from the hollow part 72 at the lower part.

[0038] The annular filter element 8 comprises three layers of filter cotton rolled into a circle from the inside out. The three layers of filter cotton fit tightly together. An iron mesh holder is provided on the inner side of the three layers of filter cotton, and the outer side is covered with a wire mesh 81 .

[0039] The main consideration is that there are a lot of impurities on the outermost side of the ring filter element 8, which will be flushed during use, and the impurities will seep down along the outer wire mesh 81 with the liquid. If the horizontal part of the conventional wire mesh 81 is easy to collect the wastewater on the upper side and not easy to seep down, it will cause secondary pollution at the junction of the ring filter element 8 and the horizontal wire mesh 81. Figure 6-7 As shown, the improvement of this solution lies in the design of the outer wire mesh 81 for covering the wastewater, which is not designed in a crisscross pattern but in an inclined pattern with a diamond-shaped cross section. The junctions of the staggered wires form wastewater nodes 82. This allows the wastewater on the upper side to flow smoothly downward along all the inclined wire meshes 81 and converge at the wastewater nodes 82 at the wire junctions. This allows the wastewater to seep down into the inclined wire mesh 81 and also drip out when the accumulated wastewater is large, thus improving the cleaning effect.

[0040] Secondly, the multi-layer filter cotton of the annular filter element 8 is not completely flat, resulting in the upper side not being level and unable to fit with the inner wall of the base, causing the exhaust gas to easily leak out directly from the upper side without being filtered through the circumferential filter cotton layers, greatly affecting the exhaust gas filtration efficiency. Therefore, see the attached Figure 8 As shown, an annular sealing cover is fitted onto the top of the annular filter element 8, which presses down the multi-layer filter cotton of the annular filter element 8. Furthermore, it is preferable that the outer side of the sealing cover is formed into an annular body extending circumferentially downward to fit the outer wire mesh 81. This is because the wire mesh 81 can be horizontal as a whole, and can more easily adhere to the annular filter element 8 through the lateral periphery to form a secondary seal, thereby improving the sealing effect.

[0041] The specific embodiments described above further illustrate the purpose, technical solutions and beneficial effects of the present invention in detail. It should be understood that the above description is only a specific embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
