Description

Technical Field

[0001] This application relates to the field of sludge drying waste gas treatment technology, and more specifically, to a spray assembly and a plate condenser. Background Technology

[0002] In the high-temperature sludge drying process, wet sludge is heated by a heat medium, and the moisture is separated from the sludge in the form of high-temperature exhaust gas. The high-temperature exhaust gas containing saturated water is cooled and condensed in a condenser to form wastewater, which is then treated as low-temperature dried exhaust gas for harmless treatment. During this process, a certain pressure difference must be maintained between the front and rear ends of the sludge drying exhaust gas treatment system to maintain the flow rate of the exhaust gas, thereby ensuring the stability of wastewater condensation and exhaust gas treatment.

[0003] Due to the high dust content in the high-temperature exhaust gas, some dust adheres to the inner surface of the condenser during its flow. If this dust is not cleaned promptly, it will gradually accumulate and form clumps of solid impurities, thus blocking the airflow channel. This affects the pressure difference between the front and rear ends of the sludge drying exhaust gas treatment system, leading to system instability and impacting the overall load of the sludge drying system. While the flushing components inside the condenser can flush its inner walls, their location limits their coverage. Typically, the flushing components are positioned at the inlet, which is often below the main flushing pipe and thus cannot be flushed, creating a blind spot. Dust accumulates in this area, forming large clumps that fall at the inlet, causing blockage of the exhaust gas flow channel.

[0004] Therefore, a spray assembly and a plate condenser are needed to solve the above problems. Utility Model Content

Figure 2 for Figure 1 The image shows a cross-sectional view of the spray assembly installed inside the condenser, AA section. Figure 3 for Figure 2The BB section view of the spray assembly installed inside the condenser is shown. Figure 4 for Figure 3 The CC-plane sectional view of the spray assembly installed inside the condenser is shown. Figure 5 for Figure 1 A schematic diagram of the spray assembly is shown. Figures 1 to 5 As shown, the spray assembly 10 includes a spray manifold 11, a supply pipe 12, and at least one spray pipe 14.

[0034] The spray manifold 11 receives the spray liquid supplied by the supply pipe 12 and supplies it to each spray pipe 14. The spray manifold 11 is typically a straight pipe extending along the central axis of the air inlet pipe 31 (exhaust gas inlet pipe) of the condenser 30 (such as a wide-channel plate condenser 30), with caps at both ends. Both the inlet and outlet of the spray manifold 11 are located on the pipe wall. The number of inlets is determined according to the required amount of spray liquid, and the number of outlets is determined according to the spray location and spray range. Typically, there is one inlet and multiple outlets, each connected to a pipe. Multiple pipes are distributed axially along the pipe wall of the spray manifold 11 at intervals. The pipe connected to the inlet is connected to the supply pipe 12, and the pipe connected to the outlet is connected to the spray pipe 14.

[0035] The supply pipe 12 is connected to the spray liquid supply source and the spray main pipe 11 respectively. Usually, the inlet of the supply pipe 12 and the spray main pipe 11 are connected by a pipe, and the outlet of the supply pipe 12 is set on the pipe wall of the supply pipe 12. The connection between the pipe and the supply pipe 12 is the water outlet. One end of the supply pipe 12 is sealed, and the other end of the supply pipe 12 is the inlet.

[0036] The spray liquid supply source provides spray liquid; the spray liquid includes, but is not limited to, rinsing water, high-pressure water, etc. The spray liquid supply source can be equipped separately, for example, by using a water pump to supply water to the supply pipe 12; or water can be taken from the rinsing component 20 in the condenser 30, that is, the rinsing water in the rinsing component 20 is used as the spray liquid supply source, thus avoiding the need for additional equipment.

[0037] The spray liquid supply source supplies liquid to the supply pipe 12, and the supply pipe 12 supplies liquid to the main spray pipe 11. The supply pipe 12 is used to transport the spray liquid supplied by the spray liquid supply source to the main spray pipe 11 through the pipeline; and then the main spray pipe 11 distributes it evenly to each spray pipe 14 through the pipeline for spraying operation.

[0038] The spray assembly 10 includes at least one spray pipe 14, and typically there are multiple spray pipes 14, which are evenly distributed along the axial direction of the main spray pipe 11. Each spray pipe 14 is connected to the main spray pipe 11, and has multiple evenly distributed spray holes 15. The spray pipes 14 spray and flush the blind area inside the condenser 30 through the spray holes 15.

[0039] The liquid supply pipe is connected to the main spray pipe 11 via a pipeline, and the main spray pipe 11 is connected to the spray pipe 14 via a pipeline. The main spray pipe 11 can be installed near the axis of the air inlet pipe 31 of the condenser 30, and the spray pipe 14 is located above the inlet of the condenser 30. The spray liquid supply source supplies high-pressure spray liquid to the supply pipe 12, the supply pipe 12 supplies high-pressure spray liquid to the main spray pipe 11, and the main spray pipe 11 supplies spray liquid to the spray pipe 14. The spray pipe 14 sprays and flushes easily clogged or difficult-to-clean areas of the condenser 30 through the spray holes 15, such as the inlet, thereby achieving rapid cleaning and unblocking.

[0040] Using the aforementioned spray assembly 10, for a condenser 30 equipped with a flushing assembly 20, the spray assembly 10 is positioned between the air inlet pipe 31 of the condenser 30 and the flushing assembly 20. The supply pipe 12 can supply flushing water from the flushing assembly 20 to the main spray pipe 11 and the spray pipe 14, allowing the spray pipe 14 to spray the flushing blind spots of the flushing assembly 20, further eliminating cleaning blind spots in the condenser 30. Moreover, for areas within the condenser 30 prone to clogging, the spray pipe 14 can be installed at multiple angles or the spray holes 15 can be installed in multiple directions for targeted spraying and flushing, achieving rapid cleaning and unblocking.

[0041] In one embodiment of this application, the supply pipe 12 is disposed in the middle of the width direction of the condenser 30, and the number of spray pipes 14 is an even number, which are respectively disposed on the left and right sides of the width direction of the condenser 30 and symmetrically arranged along the supply pipe 12.

[0042] In one embodiment of this application, the supply pipe 12 and the spray pipe 14 are arranged in parallel and at the same height, and both are located below the spray pipe 14 and the air inlet pipe 31 of the condenser 30. The extending directions of both the spray pipe 14 and the supply pipe 12 are perpendicular to the extending directions of the air inlet pipe 31 of the condenser 30 and the extending direction of the main spray pipe 11. The diameter of the supply pipe 12 is not less than the diameter of the spray pipe 14, and the diameter of the main spray pipe 11 is the largest.

[0043] Optionally, the main spray pipe 11 includes at least one inlet end and at least one outlet end. The inlet end and outlet end are respectively connected to a first connecting pipe 13 and a second connecting pipe 16. The free end of the first connecting pipe 13 is connected to the supply pipe 12, and the free end of the second connecting pipe 16 is connected to the spray pipe 14. The main spray pipe 11 is connected to the supply pipe 12 via the first connecting pipe 13, and to the spray pipe 14 via the second connecting pipe 16. The first connecting pipe 13 is used to supply liquid from the supply pipe to the main spray pipe 11, and the second connecting pipe 16 is used to discharge liquid from the main spray pipe 11 to the spray pipe 14. There is typically one inlet end and multiple outlet ends, evenly distributed on opposite sides of the inlet end. The diameter of the first connecting pipe 13 is not less than the diameter of the second connecting pipe 16. Using the above-described main spray pipe 11, the main spray pipe 11 can simultaneously meet the spraying needs of multiple spray pipes 14, achieving a good spraying effect.

[0044] In one embodiment of this application, the shapes of the first connecting pipe 13 and the second connecting pipe 16 can be determined based on the installation location and the internal space of the condenser 30. The size and number of the first connecting pipe 13 and the second connecting pipe 16 are determined based on the spray liquid flow rate. For example, one first connecting pipe 13 and two second connecting pipes 16.

[0045] To ensure that the spraying range can fully cover blind areas, optionally, multiple spray pipes 14 are used, evenly distributed along the axial direction of the main spray pipe 11. Each spray pipe 14 is connected to the outlet end of the main spray pipe 11 via a second connecting pipe 16. By increasing the number of spray pipes 14, it can be ensured that the spray pipes 14 provide a sufficiently large spraying range, and also provide sufficient flushing force for blind areas or locations prone to clogging.

[0046] The spray assembly 10 is typically configured with a symmetrical structure. Optionally, the number of spray pipes 14 is even, with each spray pipe 14 forming a pair and symmetrically distributed along the supply pipe 12. For example, there may be two spray pipes 14, forming a pair that are symmetrically distributed along the supply pipe 12. The condenser 30 has a relatively regular structure, and the symmetrical structure of the spray assembly 10 ensures that the condenser 30 is adequately sprayed and flushed, avoiding blind spots or dead zones.

[0047] In one embodiment of this application, the width of the condenser 30 is d. The spray manifold 11 is coaxially arranged with the air inlet pipe 31 of the condenser 30. The distance between both ends of the spray manifold 11 and the inner walls of both sides of the condenser 30 is 1 / 8d. The supply pipe 12 is located at 1 / 2d of the condenser 30. A spray pipe 14 is arranged on its left side at a distance of 1 / 4d from the supply pipe 12, and another spray pipe 14 is arranged on its right side at a distance of 1 / 4d from the supply pipe 12. The distance between the spray pipe 14 and the inlet of the condenser 30 is 1 / 4d, and the distance between the spray pipe 14 and the spray blind zone of the condenser 30 is 1 / 4d. This achieves full coverage of the flushing blind zone while preventing flushing water from spraying into the exhaust gas inlet pipe.

[0048] Optionally, the spray pipe 14 and the supply pipe 12 are arranged side by side or in parallel. The spray pipe 14 and the supply pipe 12 can be arranged side by side or in parallel, and the spray range of the spray pipe 14 covers the entire width of the condenser 30. The spray range mainly covers the area around the air inlet pipe 31, or areas that are prone to blockage.

[0049] Optionally, multiple spray holes 15 are arranged in an array within a preset range on the wall of the spray pipe 14. By using the above-mentioned spray pipe 14, full coverage of the flushing blind area can be achieved, while preventing flushing water from being sprayed into the exhaust gas inlet pipe.

[0050] The size, number, and position of the spray holes 15 can be set according to the specific spraying range. In one embodiment of this application, the spray holes 15 can be set on the surface of the spray pipe 14 facing the flushing pipe 22. For example, the spray holes 15 are arranged in four rows, with multiple holes in each row, and spaced apart along the axial direction of the spray pipe 14. The four rows of spray holes 15 can be set within a 90° pipe wall range, with an angle of 30° between every two adjacent spray holes 15. The diameter of the spray holes 15 is 2-5 mm, such as 3 mm. The hole diameter should ensure that the pressure of the flushing water can flush away the debris attached to the wide-channel plate condenser 30, while increasing the flushing flow rate of the flushing assembly 20, thereby comprehensively improving the flushing efficiency and achieving the effect of preventing the wide-channel plate condenser 30 from clogging.

[0051] Optionally, a nozzle is provided inside the spray hole 15. By installing a nozzle inside the spray hole 15, uniform water distribution can be achieved, water can be saved, the flushing force can be better, and the spray range can be easily controlled.

[0052] In one embodiment of this application, the nozzle can be a rotating spray head. The rotating spray head rotates during spraying, the spray angle is adjustable, and the spray range is wide, covering a larger area. Furthermore, the spray force and uniformity of the rotating spray head can be controlled by adjusting the flow rate and pressure, improving water utilization and thus saving energy.

[0053] Optionally, the spray liquid supply source includes a supply tank and a water pump. The supply tank holds the spray liquid, and the water pump pressurizes and supplies the spray liquid to the spray manifold 11 and / or spray pipe 14. The water pump can lift the spray liquid and supply it to the spray manifold 11 and / or spray pipe 14. Simultaneously, the spray liquid is pressurized, and the spray liquid sprayed from the spray holes 15 has a certain pressure to flush the condenser 30.

[0054] The following section further describes the usage process of the spray assembly 10.

[0055] The liquid supply pipe is connected to the main spray pipe 11 via the first connecting pipe 13, and the main spray pipe 11 is connected to the spray pipe 14 via the second connecting pipe 16. The main spray pipe 11 can be installed near the axis of the air inlet pipe 31 of the condenser 30, and the spray pipe 14 is located above the inlet of the condenser 30. The spray liquid supply source supplies high-pressure spray liquid to the supply pipe 12, or the supply pipe 12 obtains flushing water from the flushing assembly 20 as the spray liquid. The supply pipe 12 supplies the spray liquid to the main spray pipe 11 via the first connecting pipe 13, and the main spray pipe 11 supplies the spray liquid to the spray pipe 14 via the second connecting pipe 16. The spray pipe 14 sprays and flushes the easily clogged or difficult-to-flushed areas of the condenser 30 through the spray holes 15 or the nozzles in the spray holes 15, such as the inlet, thereby achieving rapid cleaning and unblocking.

[0056] This application also provides a plate condenser 30, including: a condenser 30 and at least one spray assembly 10 as described above.

[0057] A flushing assembly 20 is provided inside the condenser 30; a cavity is provided inside the condenser 30; an air inlet pipe 31 is provided on the condenser 30, the air inlet pipe 31 communicates with the cavity, the air inlet pipe 31 is located above the cavity, and the flushing assembly 20 is located below the air inlet pipe 31. The condenser 30 includes, but is not limited to, a wide-channel plate condenser 30.

[0058] The spray assembly 10 is connected to the flushing assembly 20, and the flushing assembly 20 serves as the source of the spray liquid. The spray assembly 10 is positioned between the flushing assembly 20 and the air inlet duct 31, and can spray and flush the area surrounding the air inlet duct 31, the area near the flushing assembly 20, or the inlet of the condenser 30. The spray range does not include the space inside the air inlet duct 31. Any of the spray assemblies described above can be used for the spray assembly 10, and will not be elaborated further here.

[0059] Using the aforementioned plate condenser 30, the spray assembly 10 extracts the rinsing water from the flushing assembly 20 as the spray liquid, expanding the rinsing area and eliminating rinsing blind spots. Because the spray liquid gains pressure from the rinsing water, it can flush away debris adhering to the wide-channel plate condenser 30, while simultaneously increasing the rinsing flow rate of the flushing assembly 20, thus comprehensively improving rinsing efficiency and achieving the anti-clogging effect of the wide-channel plate condenser 30.

[0060] Optionally, the rinsing assembly 20 includes a rinsing manifold 21 and at least one rinsing pipe 22 connected to the rinsing manifold 21; multiple rinsing pipes 22 are arranged sequentially at intervals along the axial direction of the rinsing manifold 21. The supply pipe 12 of the spray assembly 10 is disposed inside the rinsing manifold 21 and is capable of obtaining rinsing water from the rinsing manifold 21 as spray liquid. The rinsing manifold 21 is used to supply rinsing liquid to the rinsing pipes 22. The supply pipe 12 is disposed inside the rinsing manifold 21. When the rinsing water source supplies water to the rinsing manifold 21, the supply pipe 12 can obtain rinsing water and supply the rinsing water as spray liquid to the spray manifold 11, which is then sprayed by the spray pipe 14 into the rinsing blind zone of the rinsing assembly 20.

[0061] As can be seen from the above description and practice, the spray assembly and plate condenser provided in this application have the following advantages compared with the prior art: Using the above-mentioned spray assembly, for condensers equipped with a rinsing assembly, the spray assembly is positioned between the condenser's air inlet pipe and the rinsing assembly. The supply pipe can provide rinsing water from the rinsing assembly to the main spray pipe and spray pipes, allowing the spray pipes to spray the rinsing blind spots of the rinsing assembly, further eliminating cleaning blind spots in the condenser. Furthermore, for areas within the condenser prone to clogging, spray pipes can be installed at multiple angles or spray holes can be installed in multiple directions for targeted spraying and rinsing, achieving rapid cleaning and unblocking.

[0062] Those skilled in the art should understand that the above description is merely a specific embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the scope of this application should be included within the protection scope of this application.
