Description

Technical Field

[0001] This utility model relates to the field of dust removal equipment technology, specifically a sintered plastic plate flue gas dust collector. Background Technology

[0002] Industrial flue gas (such as sintering flue gas from steel plants, waste gas from chemical plants, or waste incineration flue gas) contains a large amount of dust, which not only causes air pollution but also corrodes equipment and harms human health. Sintered plastic plate dust collectors, with their advantages of high filtration accuracy, anti-condensation, and compact structure, are gradually replacing traditional baghouse dust collectors in the field of flue gas dust removal. Their core working principle is as follows: after dust-laden flue gas enters the dust collector housing, it passes through the porous filter media of the sintered plastic plate filter element under the guidance of airflow. Dust is trapped on the surface of the filter element, forming a dust layer (filter cake). The purified flue gas is discharged through the outlet. When the filter element pressure difference reaches a set value, the dust removal system is activated, peeling off the dust layer through pulse jet cleaning and other methods. The dust falls into the ash hopper and is discharged by the ash discharge device, thus regenerating the filter element.

[0003] A search revealed a patent, CN220257478U, which discloses a sintered plate dust collector for treating high-humidity flue gas. The collector includes a dehumidification mechanism with a dust collection mechanism externally mounted on top. The dehumidification mechanism includes a separation chamber with an exhaust pipe fixedly connected to its bottom left side. A cooling aluminum plate is fixedly connected inside the separation chamber. This sintered plate dust collector for treating high-humidity flue gas introduces the highly humid flue gas into the separation chamber through the exhaust pipe. A cooler cools the cooling aluminum plates, causing the highly humid flue gas to rise between multiple cooling aluminum plates. The high-humidity flue gas contacts the surface of the low-temperature cooling aluminum plates, cooling the flue gas. The water vapor in the flue gas liquefies and flows downwards through the cooling aluminum plates, exiting through the bottom of the drain port. This process separates the water vapor from the highly humid flue gas. The dried flue gas then enters the dust collection chamber through the exhaust pipe for filtration and dust removal. This structure effectively separates the water vapor from the highly humid flue gas.

[0004] The aforementioned patents have significant beneficial effects, but in practical application, they still have the following shortcomings: In the aforementioned comparative document, flue gas is filtered by horizontally arranged sintered plastic plate filter elements. However, in reality, the horizontal arrangement of the sintered plastic plate filter elements can easily cause blockage near the air inlet. When the sintered plastic plate filter elements near the air inlet become blocked, the flow efficiency of the flue gas is reduced, thus reducing the efficiency of flue gas filtration. Therefore, there is an urgent need in the art to improve the sintered plastic plate flue gas dust collector to overcome the shortcomings of the existing technology. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a sintered plastic plate flue gas dust collector, which improves the dust removal efficiency of the sintered plastic plate dust collector for flue gas.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a sintered plate flue gas dust collector, comprising a lower housing, an upper housing at the upper part of the lower housing, a first ash discharge port at the lower part of the lower housing, a gas outlet on the side of the upper housing, a gas inlet on the side of the lower housing, a fixed pipe inside the upper housing, a connecting pipe communicating with the fixed pipe on the side of the upper housing, a pulse head at the lower part of the fixed pipe, and a plurality of sintered plate filter elements inside the lower housing, with the gas inlet located below the plurality of sintered plate filter elements.

[0007] Preferably, the lower housing is provided with a bearing plate, and the bearing plate has several first through holes adapted to the sintered plastic filter element. A clamping ring is fixedly installed on the upper side of the sintered plastic filter element.

[0008] Preferably, a fixing ring adapted to the bearing plate is fixedly installed on the inner side wall of the lower housing, and the pressing plate, the bearing plate and the fixing ring are fixedly installed by bolts.

[0010] Preferably, the gas inlet is located below the guide ring, and the end of the gas inlet inside the lower housing is aligned with the side wall of the guide ring.

[0011] Preferably, a guide cone frame is fixedly installed on the upper part of the guide ring, and the guide cone frame is adapted to the through hole and is wider at the top and narrower at the bottom.

[0012] Preferably, the lower housing has a second ash outlet on its side, which is located above the guide ring.

[0013] Preferably, the lower housing and the upper housing are connected and installed via a connecting flange.

[0014] To address the shortcomings of existing technologies, this utility model provides a sintered plastic plate flue gas dust collector, overcoming the deficiencies of the prior art. The beneficial effects of this utility model are as follows: In this invention, several sintered plastic plate filter elements are set up to filter flue gas simultaneously and synchronously, thereby improving the flow efficiency of flue gas. In addition, the sintered plastic plate filter elements are cleaned regularly in conjunction with the connecting pipe, pulse head and sintered plastic plate filter elements, thereby improving the dust removal efficiency of the sintered plastic plate dust collector for flue gas.

[0015] In this invention, the use of a pressing plate, a bearing plate, and a fixing ring, along with the connection between the lower and upper housings via a mounting flange, facilitates the installation or replacement of the plastic-coated plate filter element.

[0016] In this invention, by setting a guide ring and a guide cone frame, the guide ring produces a certain condensation effect on the moisture in the flue gas, and the guide cone frame prevents the flue gas from contacting individual sintered plastic plate filter elements, thereby further improving the filtration effect of the flue gas.

[0021] 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.

[0022] Example 1 Please see Figures 1-4A sintered steel plate flue gas dust collector includes a lower housing 1, an upper housing 2 at the top of the lower housing 1, a first ash discharge port 3 at the bottom of the lower housing 1, a gas outlet 4 on the side of the upper housing 2, a gas inlet 5 on the side of the lower housing 1, a fixed pipe 6 inside the upper housing 2, a connecting pipe 7 on the side of the upper housing 2 communicating with the fixed pipe 6, a pulse head 8 at the bottom of the fixed pipe 6, a plurality of sintered steel plate filter elements 9 inside the lower housing 1, the gas inlet 5 located below the plurality of sintered steel plate filter elements 9, and a supporting tube plate 10 inside the lower housing 1. The plate 10 has several first through-holes 18 that are adapted to the sintered plastic plate filter element 9. A clamping ring 11 is fixedly installed on the upper side of the sintered plastic plate filter element 9. A clamping plate 12 is provided on the upper part of the bearing plate 10. Several second through-holes 19 that are adapted to the sintered plastic plate filter element 9 are opened through the clamping plate 12. A fixing ring 13 that is adapted to the bearing plate 10 is fixedly installed on the inner side wall of the lower housing 1. The clamping plate 12, the bearing plate 10 and the fixing ring 13 are fixedly installed by bolts. The lower housing 1 and the upper housing 2 are connected by a connecting flange.

[0023] In this embodiment, the flue gas is transported to the lower housing 1 through the gas inlet 5 when it needs to be filtered. The flue gas is transported upwards, and large particulate impurities contained in the flue gas fall to the bottom of the lower housing 1 by gravity. The flue gas passes through the sintered plastic plate filter element 9, which filters the flue gas. The filtered flue gas is then transported to the upper housing 2 and discharged through the gas outlet 4, thus achieving the filtration effect. Several sintered plastic plate filter elements 9 filter the flue gas simultaneously and synchronously, improving the flow efficiency of the flue gas and thereby improving the dust removal efficiency of the sintered plastic plate dust collector.

[0024] When the sintered plate filter element 9 reaches the specified time threshold, the high-pressure gas generating device connected to the connecting pipe 7 is turned on. The high-pressure gas generating device generates high-pressure gas, which is delivered to the fixed pipe 6 through the connecting pipe 7. The high-pressure gas in the fixed pipe 6 performs pulse dust removal on the sintered plate filter element 9 through the pulse head 8. The dust on the side of the sintered plate filter element 9 falls to the bottom of the lower housing 1, and the ash is discharged by opening the solenoid valve of the first ash discharge port 3. By periodically performing pulse treatment on the sintered plate filter element 9, the filtration effect of the flue gas is further improved.

[0025] The lower housing 1 and the upper housing 2 are connected and installed by flanges and bolts. The connecting pipe 7 and the gas outlet 4 are both installed by mounting flanges. When it is necessary to install or replace the sintered plate filter element 9, the upper housing 2, the connecting pipe 7 and the gas outlet 4 are disassembled, the upper housing 2 is lifted, the clamping plate 12 is removed, and the sintered plate filter element 9 can be taken out or installed. The sintered plate filter element 9 is inserted into the first through-hole 18 and passes through the clamping plate 12 and the supporting plate 10 by bolts. The lower end of the bolt is threaded to the fixing ring 13, which facilitates the installation or replacement of the sintered plate filter element 9. By setting the fixing ring 13, it is easy to replace the supporting plate 10 and the clamping plate 12 with different sizes of the first through-hole 18 and the second through-hole 19, which is suitable for sintered plate filter elements 9 of different sizes and improves the applicability of the sintered plate dust collector.

[0026] All of the electrical products mentioned above can be purchased from the market. They are mature technologies and have been fully disclosed, so they will not be repeated in the instruction manual. All of the electrical products mentioned above are equipped with power cords, and they are electrically connected to the external main controller and 220V phase voltage (or 380V line voltage) through the power cords. The main controller can be a conventional known device such as a computer that plays a control role.

[0027] Example 2 Please see Figures 1-4 This embodiment includes the above embodiment, and further includes: a guide ring 14 with a narrow upper part and a wide lower part is provided in the lower part of the lower housing 1, a through hole 15 is provided in the upper part of the guide ring 14, a gas inlet 5 is located below the guide ring 14, the end of the gas inlet 5 located in the lower housing 1 is aligned with the side wall of the guide ring 14, a guide cone frame 16 is fixedly installed on the upper part of the guide ring 14, the guide cone frame 16 is adapted to the through hole 15 and has a shape that is wide at the top and narrow at the bottom, and a second row of ash outlets 17 is provided on the side of the lower housing 1, the second row of ash outlets 17 is located above the guide ring 14.

[0028] In this embodiment, the flue gas is delivered to the lower housing 1 through the gas inlet 5. The flue gas impacts the guide ring 14, improving the effect of large particulate impurities falling off. The moisture contained in the flue gas contacts the lower part of the guide ring 14, producing a certain condensation effect. The condensed moisture slides down, and the flue gas contacts the guide cone frame 16 through the through hole 15. The guide cone frame 16 diffuses the flue gas to the lower part of the lower housing 1 and contacts the plastic sintered plate filter element 9, preventing the flue gas from contacting individual plastic sintered plate filter elements 9, further improving the filtration effect of the flue gas. If there are particulate impurities on the upper part of the guide ring 14, they are discharged through the second ash outlet 17.
