In addition, the three-dimensional spatial dimension of length, width and depth should be included in actual manufacture.

[0023] In order to make the purpose, technical scheme and advantage of the utility model more clear, the embodiment of the utility model will be described in further detail below with the accompanying drawings.

[0024] Please refer to Figures 1-5 The utility model provides a kind of high -efficient industrial flue gas filter device based on melt -blown non -woven fabric, comprising:

[0025] Box 101, one side of box 101 is fixedly connected with air inlet pipe 102, the other side of box 101 is fixedly connected with exhaust pipe 103, spray assembly 110 is provided in box 101, filter screen plate 105 is provided in box 101, cleaning assembly 120 is provided on filter screen plate 105, collection assembly 130 is provided on the two sides of box 101, movable assembly 140 is provided in box 101, adsorption plate 104 is provided on movable assembly 140.

[0026] Specifically, in use, the industrial flue gas generated by the melt-blown non-woven fabric enters the device through the air inlet pipe 102. Since the water source is arranged inside the box 101, the flue gas can be pretreated and cooled by the spraying assembly 110. At the same time, the water can adsorb some dust and particulate matters in the flue gas. When the sewage falls into the filter screen plate 105, the dust and particulate matters in the water can be filtered by the filter screen plate 105. When the dust and particulate matters on the filter screen plate 105 accumulate, the accumulated matters on the filter screen plate 105 can be pushed to both sides of the box 101 by the cleaning assembly 120, and collected by the collecting assembly 130 for the convenience of the staff to process. When there are some smaller particulate matters or other harmful gases, the industrial flue gas can be filtered and treated by the adsorption plate 104, so as to improve the filtering efficiency and dust capacity. Further, the adsorption plate 104 can be conveniently pulled out and replaced by the movable assembly 140, so that the staff can conveniently install, maintain and replace the filter material.

[0027] Please refer to Figures 1-3 The bottom of one side of the box 101 is provided with a water outlet 101a, and the other side of the box 101 is provided with a water inlet 101b. The inner cavity of the box 101 is fixedly connected with a partition plate 101c. The box 101 is provided with an inclined chute 101d. The bottom of the inclined chute 101d is provided with a sliding groove 101e. The filter screen plate 105 is located below the sliding groove 101e. The other side of the box 101 is provided with a pull groove 101f. The pull groove 101f is provided with fixed grooves 101g on both sides.

[0028] Specifically, the water in the box 101 can be discharged through the water outlet 101a. A certain amount of water can be added to the box 101 through the water inlet 101b. At the same time, since the valve is arranged on the water outlet 101a and the water inlet 101b, the amount of water in the box 101 can be controlled. The filter screen plate 105 and the adsorption plate 104 are separated by the partition plate 101c, which facilitates the filtration and cleaning of the industrial flue gas. The inclined chute 101d can prevent water from falling into the sliding groove 101e with particulate matters during spraying, so as to avoid affecting the work of the cleaning assembly 120. The movable assembly 140 can move in the pull groove 101f through the fixed grooves 101g.

[0029] Please refer to Figures 1-3The spraying assembly 110 comprises a water pump 110a, a spraying pipe 110b, a spraying nozzle 110c, a connecting pipe 110d and a filter box 110e. The water pump 110a is fixedly connected to the top of the box body 101. One end of the spraying pipe 110b is fixedly connected to the water pump 110a. The spraying nozzle 110c is fixedly connected to the spraying pipe 110b. One end of the connecting pipe 110d is fixedly connected to the water pump 110a. The filter box 110e is fixedly connected to the bottom of the box body 101. The other end of the connecting pipe 110d is located in the filter box 110e.

[0030] Specifically, when the industrial flue gas enters the box body 101 from the air inlet pipe 102, the water pump 110a is operated to make the connecting pipe 110d draw water from the bottom of the inner cavity of the box body 101 and spray the water out through the spraying nozzle 110c, so as to pre-treat and cool the flue gas. At the same time, the sprayed water can adsorb a part of dust and particulate matters in the flue gas. When the sewage falls into the filter screen plate 105, the dust and particulate matters in the water can be filtered through the filter screen plate 105. When the dust and particulate matters on the filter screen plate 105 are accumulated, the motor 120b is operated to rotate the screw rod 120c. Since the screw rod 120c is a reciprocating screw rod, the cleaning plate 120a slides on the sliding rod 120d, and the screw rod 120c is threadedly connected to the cleaning plate 120a, so that the cleaning plate 120a reciprocally moves on the filter screen plate 105, and the cleaning plate 120a pushes the dust accumulation on the filter screen plate 105 to the two sides of the box body 101, so as to facilitate the collection and treatment of the accumulation by the collection assembly 130. Further, since the other end of the connecting pipe 110d is located in the filter box 110e, and the filter box 110e is fixedly connected to the bottom of the box body 101, the water pump 110a can be prevented from being affected by the particulate matters in the water when drawing water from the bottom of the box body 101.

[0031] Please refer to Figures 1-4 The collection assembly 130 comprises a rotating plate 130a, a collection box 130b, a fixed plate 130c and a protruding block 130d. The two sides of the box body 101 are provided with placing grooves 130e, and the placing grooves 130e are provided with recesses 130f. The rotating plate 130a is rotationally connected to the two sides of the box body 101. The protruding block 130d is fixedly connected to the fixed plate 130c. The collection box 130b is fixedly connected to the fixed plate 130c.

[0032] Specifically, when the cleaning plate 120a moves to both sides of the inner cavity of the box body 101, the convex rod 120e on the cleaning plate 120a will contact the rotating plate 130a, so that the convex rod 120e pushes the rotating plate 130a to rotate, thereby opening the rotating plate 130a, so that the cleaning plate 120a can push the dust and other accumulated objects into the collection box 130b, facilitating the handling of the staff; further, when the convex rod 120e leaves the rotating plate 130a, the rotating plate 130a will rotate to the original position, avoiding the leakage of smoke from the box body 101; when the collection assembly 130 needs to be replaced, by placing the fixed plate 130c into the placement slot 130e and fixing it in the groove 130f through the convex blocks 130d on both sides of the fixed plate 130c, the fixed plate 130c can be fixed in the placement slot 130e, thereby avoiding the activation of the collection assembly 130 during the use of the device, affecting the processing of the filtered smoke.

[0033] Please refer to Figures 1-5 The movable assembly 140 includes a pull-out plate 140a, a fixed rod 140b, a pull plate 140c, a wedge block 140d, and a spring 140e. The pull-out plate 140a is provided with a pressing groove 140f and a movable groove 140g. The fixed rod 140b is fixedly connected in the pressing groove 140f. One side of the pull plate 140c is fixedly connected with the wedge block 140d, and the other side is fixedly connected with one end of the spring 140e. The other end of the spring 140e is fixedly connected to the inner wall of the pressing groove 140f. The adsorption plate 104 includes an activated carbon adsorption plate 104a, a fine particle adsorption plate 104b, and an oxidation adsorption plate 104c. The activated carbon adsorption plate 104a is located in one of the movable grooves 140g, the fine particle adsorption plate 104b is located in the other movable groove 140g, and the oxidation adsorption plate 104c is located in one of the movable grooves 140g.

[0034] Specifically, when part of the smoke passes through the filter screen plate 105, the device can pass through multiple adsorption plates 104, which can perform hierarchical processing on the smoke. The activated carbon adsorption plate 104a is used to adsorb gaseous pollutants such as ammonia, sulfides, methyl sulfate, benzene, etc. The fine particle adsorption plate 104b is used to adsorb smaller particles and conventional organic matter in the airflow. The oxidation adsorption plate 104c is used to convert certain gaseous toxic substances such as sulfur dioxide, carbon monoxide, etc. and volatile organic compounds, thereby achieving hierarchical filtration of smoke and improving filtration efficiency and dust capacity. When the adsorption plate 104 needs to be replaced, the pull plate 140c is pressed to move the wedge block 140d, so that the wedge block 140d moves away from the fixed groove 101g, thereby pulling the pull-out plate 140a, so that the pull plate 140a moves with the adsorption plate 104 in the pull slot 101f, thereby facilitating the replacement of the adsorption plate, and facilitating the installation, maintenance and replacement of filter materials by the staff.
