Description

Technical Field

[0001] The present invention belongs to the technical field of plasma tail gas cooling, and particularly relates to a plasma tail gas cooling system that synergistically combines water curtain guiding forming and kinetic energy honeycomb dissipation. Background Art

[0002] Traditional plasma tail gas cooling systems have problems such as the water curtain being easily vaporized by high temperatures, the airflow being disturbed and becoming unstable, and the cooling structure being damaged by the impact of the flame. This makes it difficult for the water curtain and the plasma tail gas to achieve relatively sufficient contact, reducing the contact heat efficiency. In addition, there is a lack of a flame blocking and kinetic energy dissipation module, and the tail flame of the flame will enter the cooling chamber, thereby damaging the integrity of the water curtain and being unable to balance the heat exchange efficiency and anti-impact stability. Summary of the Invention

[0003] Object of the Invention: In order to overcome the deficiencies in the prior art, the present invention provides a plasma tail gas cooling system that synergistically combines water curtain guiding forming and kinetic energy honeycomb dissipation. By using the water curtain as a cooling medium and the honeycomb plate to reduce the flame impact, the two together form a double protection of a heat barrier and kinetic energy dissipation, ensuring the stability of plasma tail gas cooling and improving the efficiency.

[0004] Technical Solution: To achieve the above object, the plasma tail gas cooling system of the present invention that synergistically combines water curtain guiding forming and kinetic energy honeycomb dissipation includes a cooling chamber. At the top of the cooling chamber, there are coaxially arranged a water distribution ring, an air distribution ring, and a blocking and force-dissipating honeycomb plate from the outside to the inside. At the bottom of the cooling chamber, there is a water collection ring; a water guiding rod is provided from the water distribution port of the water distribution ring to the water collection port of the water collection ring. Through this water guiding rod, cooling water is guided to form water columns, and several circumferentially arranged water columns form an annular array water curtain; the tail gas treated by the plasma flame is distributed into the cooling chamber through the air distribution ring; the blocking and force-dissipating honeycomb plate blocks the plasma flame from entering the cooling chamber and divides and accommodates the tail flame through uniformly distributed honeycomb holes to dissipate the force of the plasma flame.

[0005] Further, the diameter of the water guiding rod is smaller than the inner diameters of the water distribution port and the water collection port. The upper end of the water guiding rod extends coaxially into the water distribution port and is connected to the water distribution ring, and the lower end of the water guiding rod extends coaxially into the water collection port and is connected to the water collection ring.

[0006] Further, it includes a water distribution power source and a water collection power source; the water distribution power source is docked with the water supply pipe of the water distribution ring to provide the water distribution power to the water distribution port; the water collection power source is docked with the return water pipe of the water collection ring to provide the water collection power to the water collection port; the water distribution power and the water collection power form a co-directional double-power combination for the water columns to enhance the morphological stability of the continuous flow of the water columns along the water guiding rod.

[0007] Further, the top of the air distribution ring is provided with an air inlet, and the bottom is provided with air distribution holes. The air inlet faces upward, and the air distribution holes are evenly distributed.

[0008] Furthermore, a bottom cavity is provided at the inner bottom of the flame-blocking and force-discharging honeycomb plate. The bottom cavity is located below the honeycomb holes, and each of the honeycomb holes communicates with the bottom cavity. An annular cavity is provided at the inner side of the flame-blocking and force-discharging honeycomb plate. The annular cavity surrounds and communicates with the bottom cavity. An annular diversion channel is provided on the upper plate surface of the flame-blocking and force-discharging honeycomb plate. The initial port of the annular diversion channel communicates with the annular cavity, and the annular diversion channel is bent outward in an arc shape so that its end port faces downward toward the air inlet of the air distribution ring. When the tail flame of the plasma flame sprays onto the upper plate surface of the flame-blocking and force-discharging honeycomb plate, it is dispersed into each honeycomb hole through the honeycomb holes for force discharging of the plasma flame. The bottom cavity blocks the flame from entering the cooling cavity through the bottom wall, and the exhaust gas carried in the plasma flame is sprayed into the air distribution ring through the honeycomb holes, the bottom cavity, the annular cavity, and the annular diversion channel in sequence and then enters the air distribution ring through the air inlet.

[0009] Furthermore, the height of the bottom wall of the bottom cavity gradually decreases from the center to the edge, forming a slope surface. The flame that enters the bottom cavity from the honeycomb holes and carries exhaust gas is guided along the slope surface to spread to the edge position where the annular cavity is located, so as to promote the discharge of the exhaust gas entering the flame-blocking and force-discharging honeycomb plate.

[0010] Furthermore, the inner edge of the bottom cavity is processed with a radian to form a radian surface. The lower end of the slope surface is connected to the lower end of the radian surface, and the upper end of the slope surface is tangent to the annular cavity, so as to receive the flame carrying exhaust gas flowing along the slope surface and redirect it into the annular cavity.

[0011] Furthermore, the cross-sectional shape of the honeycomb hole is polygonal, and the extending shape from the inlet to the outlet of the honeycomb hole is gradually expanding.

[0012] Furthermore, a transverse fastener penetrating the annular cavity is provided on the outer periphery of the flame-blocking and force-discharging honeycomb plate. A lapping plate extending toward the water distribution ring is connected to the air distribution ring, and a support plate for supporting the flame-blocking and force-discharging honeycomb plate is provided on the inner ring of the air distribution ring. The water guide rod and the water distribution ring, the water guide rod and the water collection ring, the lapping plate and the water distribution ring, and the flame-blocking and force-discharging honeycomb plate and the support plate are respectively connected by vertical fasteners.

[0013] Furthermore, an upper interface is provided at the top of the cooling cavity. The upper interface, the water distribution ring, and the cooling cavity are connected in sequence, and the upper interface is docked with the combustion cavity of the plasma exhaust gas treatment equipment.

[0014] A lower interface is provided at the bottom of the cooling cavity. The water collection ring, the lower interface, and the cooling cavity are connected in sequence, and the lower interface is docked with the dust collection water tank.

[0015] Beneficial effects: The water guide rod of the present invention is coaxially connected through the water distribution port and the water collection port, constraining the water flow into a columnar shape, and arranging it circumferentially to form an annular array water curtain. The annular water curtain covers the cooling chamber, and efficient heat exchange is achieved through the direct contact between water and the tail gas. The honeycomb holes divide the plasma flame through a uniform distribution structure, reducing the kinetic energy of the flame. The bottom chamber blocks the flame from entering the cooling chamber, increasing the contact area between the inner wall of the honeycomb holes and the flame, accelerating energy dissipation. At the same time, the bottom chamber physically isolates the flame, realizing the provision of a cooling medium through the water curtain. The honeycomb plate reduces the flame impact, and the two jointly form a dual protection of a heat barrier and kinetic energy dissipation, ensuring the stability of plasma tail gas cooling and improving the efficiency.

[0020] The present invention will be further described in detail below with reference to the accompanying drawings.

[0021] As Figure 1 , Figure 2 , Figure 3 and Figure 4As shown in the figure, a plasma tail gas cooling system that combines water curtain guiding forming and kinetic energy honeycomb dissipation includes a cooling chamber 1. At the top of the cooling chamber 1, there are coaxially arranged a water distribution ring 2, a gas distribution ring 3, and a blocking and force-dissipating honeycomb plate 4 from outside to inside. At the bottom of the cooling chamber 1, there is a water collection ring 7. A water guiding rod 5 is arranged from the water distribution port 20 of the water distribution ring 2 to the water collection port 70 of the water collection ring 7. Through this water guiding rod 5, cooling water is guided to form water columns, and several circumferentially arranged water columns form an annular array water curtain. The tail gas treated by the plasma flame is distributed into the cooling chamber 1 through the gas distribution ring 3. At the inner bottom of the blocking and force-dissipating honeycomb plate 4, there is a bottom chamber 41. The blocking and force-dissipating honeycomb plate 4 blocks the plasma flame from entering the cooling chamber 1, and divides and accommodates the tail flame through uniformly distributed honeycomb holes 40 to dissipate the force of the plasma flame. In the present invention, the water guiding rod 5 connects the water distribution port 20 and the water collection port 70 coaxially, constrains the water flow into a columnar shape, and forms an annular array water curtain through circumferential arrangement. The annular water curtain covers the cooling chamber 1, and efficient heat exchange is achieved through the direct contact between water and the tail gas. The honeycomb holes 40 divide the plasma flame through a uniform distribution structure, reducing the kinetic energy of the flame. The bottom chamber 41 blocks the flame from entering the cooling chamber 1, increasing the contact area between the inner wall of the honeycomb holes 40 and the flame, accelerating energy dissipation. At the same time, the bottom chamber 41 physically isolates the flame, realizing the provision of a cooling medium through the water curtain, and the honeycomb plate reduces the flame impact. The two jointly form the purpose of dual protection of heat barrier and kinetic energy dissipation, ensuring the stability of plasma tail gas cooling and improving the efficiency.

[0022] As Figure 3 and Figure 4 shown, the diameter of the water guiding rod 5 is smaller than the inner diameters of the water distribution port 20 and the water collection port 70, so that the water guiding rod 5 forms annular gaps with the water distribution port 20 and the water collection port 70 respectively. The water flow forms a stable wall-attached flow in the annular gaps, reducing the dispersion caused by turbulence. The upper end of the water guiding rod 5 extends coaxially into the water distribution port 20 and is connected to the water distribution ring 2. The lower end of the water guiding rod 5 extends coaxially into the water collection port 70 and is connected to the water collection ring 7. The upper and lower ends of the water guiding rod 5 are respectively inserted into the water distribution port 20 and the water collection port 70, and are kept coaxially aligned to ensure that the water flow flows along the rod, avoiding local pressure unevenness caused by eccentric water flow and maintaining the water column shape.

[0023] As Figure 1 shown, the present invention includes a water distribution power source 2a and a water collection power source 7a. The water distribution power source 2a is docked with the water supply pipe 21 of the water distribution ring 2 to provide the water distribution power for the water distribution port 20. The water collection power source 7a is docked with the water return pipe 71 of the water collection ring 7 to provide the water collection power for the water collection port 70. The water distribution power and the water collection power form a co-directional dual-power combination for the water column to enhance the morphological stability of the continuous flow of the water column along the water guiding rod 5. The water power source 2a (pressurized water supply) and the water collection power source 7a (negative pressure suction) jointly drive the water flow. The water distribution power provides a positive pressure, and the water collection power eliminates the back pressure, forming a stable pressure difference to ensure continuous water flow.

[0024] In the present invention, to ensure the stability of plasma tail gas cooling and improve the efficiency, it should be noted that the arrangements of the water guide rod 5 and the flame-blocking and force-dissipating honeycomb plate 4 both have the effect of improving the stability of the water curtain form. The water guide rod 5 can strengthen the water curtain form, and the flame-blocking and force-dissipating honeycomb plate 4 can block and dissipate the flame, preventing the flame from entering the cooling chamber 1 and destroying the water curtain form. The specific analysis is as follows:

[0025] 1) The direct function of the water guide rod 5:

[0026] 1.1) Form strengthening: Through the physical guidance of the water guide rod 5, the water flow is constrained into regular water columns, forming an annular array water curtain, avoiding the dispersion of the water flow due to the interference of gravity or air flow;

[0027] 1.2) Dynamic balance: The double power sources of water distribution / water collection transmit power through the water guide rod 5 to ensure the continuity of the water column flow and prevent the water curtain from breaking.

[0028] 2) The indirect protection of the flame-blocking and force-dissipating honeycomb plate 4:

[0029] 2.1) Flame blocking: The honeycomb plate, as a physical barrier, directly intercepts the plasma flame, avoiding the direct impact of the high-temperature jet on the water curtain, resulting in vaporization or disorder.

[0030] 2.2) Kinetic energy dissipation: After the honeycomb holes 40 divide the flame, the gradually expanding shape design of the honeycomb holes 40 reduces the flow rate and pressure, reduces the impact force, and improves the stability.

[0031] The water guide rod 5 maintains the stability of the water column from the inside, and the flame-blocking and force-dissipating honeycomb plate 4 eliminates the flame interference from the outside. The two form an "internal and external dual" protection to jointly ensure the integrity and cooling efficiency of the water curtain.

[0032] As Figure 3 shown, an air inlet 30 is provided at the top of the air distribution ring 3. The tail gas enters the air distribution ring 3 from the top, and air distribution holes 31 are provided at the bottom. The air inlet 30 faces upward, and the air distribution holes 31 are evenly distributed to ensure that the opening density and direction at the bottom of the air distribution ring 3 are consistent. The tail gas uniformly diffuses in the inner cavity of the air distribution ring 3 and then enters the cooling chamber 1 through the air distribution holes 31, avoiding excessive local concentration.

[0033] As Figure 2 and Figure 3As shown, the bottom cavity 41 is located below the honeycomb holes 40, and each of the honeycomb holes 40 communicates with the bottom cavity 41; an annular cavity 42 is provided at the inner side of the flame-blocking and pressure-relieving honeycomb plate 4, and the annular cavity 42 surrounds and communicates with the bottom cavity 41; an annular diversion channel 43 is provided on the upper plate surface of the flame-blocking and pressure-relieving honeycomb plate 4, the initial port of the annular diversion channel 43 communicates with the annular cavity 42, and the annular diversion channel 43 is bent outward in an arc until its end port faces downward toward the air inlet 30 of the air distribution ring 3; when the tail flame of the plasma flame sprays onto the upper plate surface of the flame-blocking and pressure-relieving honeycomb plate 4, it is divided by the honeycomb holes 40 and dispersed into each honeycomb hole 40 to achieve pressure relief of the plasma flame. The bottom cavity 41 blocks the flame from entering the cooling cavity 1 through the bottom wall. The tail gas carried in the plasma flame sequentially passes through the honeycomb holes 40, the bottom cavity 41, the annular cavity 42, and the annular diversion channel 43 and sprays toward the air inlet 30 to enter the air distribution ring 3. Most of the tail gas enters the air distribution ring 3 through the air inlet 30, and a small part of the tail gas is mixed in the flame. After the flame is divided by the honeycomb holes 40, this small part of the tail gas mixed in the flame is collected to the annular cavity 42 through the bottom cavity 41 and then guided to the air inlet 30 of the air distribution ring 3 through the annular diversion channel 43, so that this small part of the tail gas also enters the air distribution ring 3, and then is distributed to the cooling cavity 1 for water curtain cooling, improving the thoroughness and efficiency of tail gas cooling.

[0034] As Figure 3 shown, the height of the bottom wall of the bottom cavity 41 gradually decreases from the center to the edge, forming a slope surface 410 with a slope. The flame that enters the bottom cavity 41 from the honeycomb holes 40 and carries tail gas is guided along the slope surface 410 and diffuses to the edge position where the annular cavity 42 is located to promote the discharge of the tail gas entering the flame-blocking and pressure-relieving honeycomb plate 4. The tail gas carries particulate matter and slides along the slope to the annular cavity 42, reducing bottom cavity deposition. The slope reduces the gas flow resistance, thus promoting the rapid discharge of the tail gas. Due to the driving force of the divided flame and the driving effect of the tail gas itself, considering the space limitation problem, the slope angle does not need to be too large, and a range of 3 - 10° is sufficient.

[0035] The inner edge of the bottom cavity 41 is processed with an arc to form an arc surface 411. The lower end of the slope surface 410 is connected to the lower end of the arc surface 411, and the upper end of the slope surface 410 is tangent to the annular cavity 42 to receive the flame carrying tail gas guided along the slope surface 410 and redirect it into the annular cavity 42. The arc surface 411 reduces the eddy current and pressure loss caused by the sharp turn of the air flow, improving the flow efficiency. At the same time, the smooth transition can avoid the accumulation of particulate matter at the corner.

[0036] More specifically, the cross-sectional shape of the honeycomb holes 40 is polygonal. A polygonal shape is more conducive to flame discretization than a circular hole, and the extension shape of the honeycomb holes 40 from the inlet to the outlet is gradually expanding. The gradually expanding structure reduces the outlet flow rate and the impact of the flame and the exhaust gas mixed in the flame on the downstream structure. The blocking and pressure-relieving honeycomb plate 4 is made of a high-temperature resistant ceramic matrix composite material to resist thermal stress deformation.

[0037] As Figure 2 , Figure 3 and Figure 4 shown, a transverse fastener 6 penetrating the annular cavity 42 is provided on the outer periphery of the blocking and pressure-relieving honeycomb plate 4; a lapping plate 12 extending towards the water distribution ring 2 is connected to the gas distribution ring 3, and a support plate 8 for supporting the blocking and pressure-relieving honeycomb plate 4 is provided on the inner ring of the gas distribution ring 3; vertical fasteners 9 are respectively connected between the water guide rod 5 and the water distribution ring 2, between the water guide rod 5 and the water collection ring 7, between the lapping plate 12 and the water distribution ring 2, and between the blocking and pressure-relieving honeycomb plate 4 and the support plate 8. The transverse fastener 6 is a transverse bolt, and the vertical fastener 9 is a vertical bolt. Key components of the entire cooling system are all assembled in a detachable manner, which is convenient for maintenance and replacement, reduces the downtime for maintenance, and improves the equipment utilization rate.

[0038] As Figure 1 shown, an upper interface 10 is provided at the top of the cooling cavity 1. The upper interface 10, the water distribution ring 2 and the cooling cavity 1 are connected in sequence, and the upper interface 10 is docked with the combustion cavity of the plasma exhaust gas treatment equipment; a lower interface 11 is provided at the bottom of the cooling cavity 1. The water collection ring 7, the lower interface 11 and the cooling cavity 1 are connected in sequence, and the lower interface 11 is docked with the dust collection water tank.

[0039] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can still be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
