The device includes a recovery tank. A filter mechanism is arranged on one side of the recovery tank, and a collection mechanism is arranged on the other side of the recovery tank. A waste heat recovery device is arranged on the inner side of the recovery tank. The filter mechanism includes a support plate, and a filter box is fixed on the top side of the support plate. A sliding groove is formed in the inner side of the filter box, and a filter screen is slidingly installed in the sliding groove. A fixed block is fixed to one end of the filter screen, and the fixed block is buckled on one side of the filter box. Sealing pads are fixed to the two sides of the fixed block. Steam is introduced through the air inlet, and the filter screen filters out impurities in the steam. When the filter screen needs to be replaced, the handle can be pulled out of the filter box. Then, the replaced filter screen is installed in the inner side of the sliding groove. With the cooperation of the sealing pads, steam leakage during the filtering process can be prevented. The existing waste heat recovery device is inconvenient to maintain, which reduces the recovery efficiency.

[0004] Although the above-mentioned steam waste heat recovery device is provided with a filter screen to filter impurities in the steam and prevent impurities from accumulating on the pipe wall to affect the steam waste heat recovery efficiency, the filter plate needs to be replaced regularly by personnel. Before the filter screen is replaced, impurities will adhere to the surface of the filter screen, which will still affect the steam flow rate before the filter screen is cleaned. In addition, the area of the steam blown onto the filter screen in the above-mentioned steam waste heat recovery device is limited, and the steam contains heat. Therefore, long-term use can cause local fatigue of the filter screen, resulting in relaxation of the filter screen and affecting the filtering effect of impurities.

[0005] Therefore, a steam heat supply waste heat recovery device is proposed to solve the above-mentioned problems. UTILITY MODEL CONTENTS

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] In practical implementation: such as Figures 1-4 As shown, a steam heating waste heat recovery device includes: a housing 1 and a collection shell 2 connected to its air inlet end via a pipe 301, wherein a filter plate 4 is provided in the collection shell 2; and a cleaning and dispersing component 3, which is provided at the air inlet end of the collection shell 2.

[0026] Waste heat recovery usually refers to the technology of reusing high-temperature waste gas generated during industrial processing, and recovering waste heat steam to improve resource utilization.

[0027] It should be noted that: the box 1 is a waste heat recovery device, for capturing the waste heat generated in the steam after impurity removal, converting it into usable heat or electricity, thereby improving energy utilization efficiency, reducing energy consumption, and reducing environmental pollution. The waste heat recovery device is a relatively mature product in the prior art, and will not be described here;

[0028] As Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, the cleaning and dispersing assembly 3 includes a pipe 301 connected to the inlet end of the collection shell 2, the pipe 301 is provided with a movable shell 303, the movable shell 303 is provided with an impeller 306, the impeller 306 is fixedly connected with a connecting rod 304, one end of the connecting rod 304 close to the filter plate 4 is fixedly connected with a scraper 305, one side of the scraper 305 is in contact with the filter plate 4; the outlet port of the pipe 301 is larger than the inlet port, and the outlet end of the pipe 301 is in communication with the collection shell 2; the surface of the impeller 306 is annularly arranged with six blades, the blades of the impeller 306 are inclined, and the blade ends of the impeller 306 are fixedly connected with the inner wall of the movable shell 303;

[0029] When the waste heat of the steam is recovered, the steam first needs to pass through the pipe 301 into the collection shell 2 for impurity removal. When the steam flows in the pipe 301, it first contacts the impeller 306 in the movable shell 303. Because the blades on the surface of the impeller 306 are inclined, the steam will cause the impeller 306 to rotate by gas extrusion. When the impeller 306 rotates, the steam entering the collection shell 2 through the impeller 306 will be changed in direction and uniformly blown to the surface of the filter plate 4 for impurity removal, which can effectively improve the overall utilization rate of the filter plate 4, and also can avoid the problem of local fatigue of the filter plate 4 caused by the steam blowing to a certain part of the filter plate 4 for a long time;

[0030] The inner wall of the pipe 301 is fixedly connected with a guide rail 302, the guide rail 302 is slidingly connected with a movable ring 307, and the inner wall of the movable ring 307 is fixedly connected with the movable shell 303;

[0031] As Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, the scraper 305 is annularly arranged with three, the edge of the scraper 305 is inclined; the surface of the connecting rod 304 is fixedly connected with a bearing seat, and both ends of the bearing seat are fixedly connected with the inner wall of the pipe 301;

[0032] When the impeller 306 rotates, the connecting rod 304 will drive the scraper 305 to rotate on the surface of the filter plate 4 along with the impeller 306, and the impurities on the surface of the filter plate 4 are scraped, achieving the effect of continuous cleaning, and at the same time, the manpower and time consumed by manual removal and cleaning can be reduced, and the flow rate of steam is ensured not to be limited.

[0033] The collecting shell 2 is provided with sockets on both sides, and the filter plate 4 is inserted between the two sockets.

[0034] Working principle: when the waste heat of steam is recovered, the steam needs to pass through the pipeline 301 into the collecting shell 2 for impurity removal. When the steam flows in the pipeline 301, the steam first contacts the impeller 306 in the movable shell 303. Since the blades on the surface of the impeller 306 are inclined, the steam will be extruded by the gas to make the impeller 306 rotate. When the impeller 306 rotates, the steam entering the collecting shell 2 through the impeller 306 will be changed in direction and uniformly blown to the surface of the filter plate 4 for impurity removal, which can effectively improve the overall utilization rate of the filter plate 4, and can also avoid the problem of local fatigue of the filter plate 4 caused by the steam blowing to a certain part of the filter plate 4 for a long time. When the impeller 306 rotates, the connecting rod 304 will drive the scraper 305 to rotate on the surface of the filter plate 4 along with the impeller 306, and the impurities on the surface of the filter plate 4 are scraped, achieving the effect of continuous cleaning, and at the same time, the flow rate of steam is ensured.

[0035] In addition, it should be understood that although the present specification is described in terms of embodiments, not every embodiment contains only one independent technical solution, and the description of the specification is only for the sake of clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can be appropriately combined to form other embodiments that those skilled in the art can understand.
