Description

Technical Field

[0001] The utility model relates to the technical field of kiln fume treatment, in particular to kiln fume treatment equipment. Background Art

[0002] Industrial kilns can be divided into two categories according to the thermal system: one is the intermittent kiln, also known as the periodic kiln, which is characterized by intermittent production of the kiln, and the temperature of the kiln changes in each heating cycle, such as chamber kilns, trolley kilns, pit kilns, etc.; the second is the continuous kiln, which is characterized by continuous production of the kiln, and the kiln chamber is divided into temperature sections. During the heating process, the temperature of each section is constant, and the workpiece gradually enters the high-temperature heating zone from the low-temperature preheating zone, such as continuous heating kilns and heat treatment kilns, ring kilns, walking kilns, vibrating bottom kilns, etc.

[0003] Industrial kilns need to be heated when they are working, and exhaust gas will be produced when the fuel is burned. These exhaust gases contain flue gas particles and cannot be directly discharged into the environment, which will cause environmental pollution. For this reason, we have proposed a device for industrial kiln flue gas treatment.

[0004] In the prior art, a Chinese patent with a publication number of CN219023722U is proposed to solve the above-mentioned technical problems. The technical solution disclosed in the patent document is as follows: a kiln flue gas treatment device, including a lower hopper, a tank body, a top cover and an air inlet pipe, the bottom end of the tank body is provided with a lower hopper, the top of the tank body is provided with a top cover, the top of the top cover is provided with an air outlet pipe, the inside of the tank body is fixed with a first liquid distribution pipe and a second liquid distribution pipe by a fixing card, the upper surface of the first liquid distribution pipe and the lower surface of the second liquid distribution pipe are both provided with liquid outlets, and an air intake nozzle is installed on the tank body between the first liquid distribution pipe and the second liquid distribution pipe. The utility model increases the washing effect and improves the washing efficiency by flushing the gas from the upper and lower sides of the air intake nozzle. In the existing direct spraying, the spraying of the nozzle has a range. When the air intake speed is too fast, the flue gas does not contact the sprayed desulfurizer thoroughly enough, resulting in poor flue gas treatment effect. Utility Model Content

[0005] The purpose of the utility model is to provide a kiln fume treatment device to solve the problems raised in the above background technology.

[0006] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0007] A kiln fume treatment device comprises a treatment tower and a bracket; a water tank is arranged on the top of the treatment tower, and the water tank is annular; an air inlet is arranged at the center of the water tank, and an air inlet pipe is fixedly connected to the air inlet; a spray plate is arranged at a position below the water tank in the water tank, and a pressurized water pump is arranged in the water tank, one end of the water pump is connected to the water tank, and the other end is connected to the spray plate; a plurality of spray convex heads are arranged on the spray plate, and a plurality of nozzles are fixedly connected to the lower end of the spray convex head, and the nozzles are connected to the spray convex head; a spray plate is arranged at the center of the spray plate A first air duct is connected to the air inlet; a diverter plate is fixedly provided below the spray plate, a second air duct is provided at the top of the diverter plate, and the second air duct is connected to the first air duct; a plurality of diverter pipes are provided below the diverter plate, a spray port is provided at the upper end of the diverter plate, the spray port, the spray convex head and the diverter pipe are all concentrically arranged, and the diameter of the spray convex head and the spray port are the same; a collecting component and an exhaust pipe are fixedly connected below the diverter pipe, the exhaust pipe is connected to the inside of the collecting component, and the collecting component and the diverter pipe are connected.

[0008] When the flue gas is treated, the flue gas is input from the air inlet on the top of the water tank. The flue gas is input through the air inlet, transmitted to the second air channel through the first air channel on the spray plate, and enters the diverter plate. At this time, the spray convex head of the spray plate matches the spray port on the diverter pipe, so that the upper end of the diverter plate does not leak. Then the nozzle sprays the desulfurizer, and the flue gas entering the air inlet is diverted through the diverter plate, and then the desulfurizer is sprayed out through the nozzle, so that the flue gas treatment is more complete, and the treated flue gas is discharged through the exhaust pipe, thereby preventing incomplete flue gas treatment.

[0009] A further improvement of the technical solution of the utility model is that: the collecting component includes a collecting chamber, a through hole is provided at the upper end of the collecting chamber, and the size, position and number of the through hole are consistent with the diversion pipe; below the collecting chamber is a waste chamber, a material pipe and a water filter port are provided at the bottom of the waste chamber, and a filter plate is provided on the water filter port.

[0010] The above technical scheme is adopted. In this scheme, a collection chamber is set up, and the sprayed desulfurizer will flow down after treating the flue gas. The waste liquid will be accompanied by some impurities and precipitates produced by the reaction. By setting a material pipe and a water filter port, the precipitate can be discharged through the material pipe, and the liquid will leak out through the filter plate, thereby separating the solid and liquid.

[0011] A further improvement of the technical solution of the utility model is that the filter plate is in a truncated cone shape, and a filter hole is provided at the top of the filter plate.

[0012] By adopting the above technical solution, a filter hole is opened through the top of the filter plate, and the solid will slide down from the side end of the truncated cone, preventing the solid from precipitating and accumulating on the filter hole, causing the filter plate to be blocked and reducing the separation effect.

[0013] A further improvement of the technical solution of the utility model is that the waste cavity is in the shape of an inverted cone.

[0014] The above technical solution is adopted, in which the shape of the waste chamber is set to be an inverted cone, so that the waste liquid can quickly gather at the bottom of the waste box.

[0015] A further improvement of the technical solution of the utility model is that a partition is provided below the outlet of the exhaust pipe in the collecting chamber, and a waste opening is provided at the center of the partition.

[0016] The above technical solution is adopted. In this solution, a partition is provided. The partition can block the gas discharged from the shunt pipe to a certain extent, preventing most of the discharged gas from escaping from the collecting chamber.

[0017] A further improvement of the technical solution of the utility model is that the filter plate is slidably connected to the water filter port.

[0018] The above technical solution is adopted, in which a filter plate is slidably connected to the water filter port. Some small sediments and fertilizers are easy to block the water filter port. By setting the filter plate slidably connected to the water filter port, when the water filter port is blocked, the filter plate can be slid out and cleaned.

[0019] A further improvement of the technical solution of the utility model is that a corrugated plate is fixedly provided in the exhaust pipe.

[0020] The above technical solution is adopted, in which a corrugated plate is set up, and the water vapor in the flue gas hits the corrugated plate and is captured, and the droplets gather to form a water flow, which falls into the slurry pool due to gravity, thereby achieving gas-liquid separation, so that the flue gas flowing through the demister meets the demisting requirements and is discharged.

[0021] Due to the adoption of the above technical solution, the utility model has achieved the following technical progress compared with the prior art:

[0022] 1. The utility model provides a kiln flue gas treatment device. When the flue gas is treated, the flue gas is input from the air inlet on the top of the water tank, and the flue gas is input through the air inlet and transmitted to the second air channel through the first air channel on the spray plate, and enters the diverter plate. At this time, the spray convex head of the spray plate is matched with the spray port on the diverter pipe, so that the upper end of the diverter plate does not leak. Then the nozzle sprays the desulfurizer, and the flue gas entering the air inlet is diverted through the diverter plate, and then the desulfurizer is sprayed out through the nozzle, so that the treatment of the flue gas is more complete, and the treated flue gas is discharged through the exhaust pipe; to prevent the occurrence of incomplete treatment of the flue gas.

[0023] 2. The utility model provides a kiln flue gas treatment equipment. The desulfurizer will flow down after treating the flue gas. The waste liquid will be accompanied by some impurities and precipitates produced by the reaction. By setting a material pipe and a water filter port, the precipitate can be discharged through the material pipe, and the liquid will leak out through the filter plate, so that the solid and liquid are separated.

[0024] 3. The utility model provides a kiln flue gas treatment equipment. By setting a corrugated plate, water vapor in the flue gas hits the corrugated plate and is captured, and the mist droplets gather to form a water flow, which falls into the slurry pool due to gravity, realizing gas-liquid separation, so that the flue gas flowing through the demister meets the demisting requirements and is discharged.

DETAILED DESCRIPTION

[0032] The present invention is further described in detail below in conjunction with the embodiments:

[0033] like Figure 1-5As shown, the utility model provides a kiln fume treatment device, including a treatment tower 1 and a bracket 2; a water tank 3 is provided on the top of the treatment tower 1, and the water tank 3 is annular; an air inlet is provided at the center of the water tank 3, and an air inlet pipe 4 is fixedly connected to the air inlet; a spray plate 5 is provided at a position below the water tank 3 in the water tank 3, and a pressurized water pump is provided in the water tank 3, one end of the water pump is connected to the water tank 3, and the other end is connected to the spray plate 5; a plurality of spray convex heads 6 are provided on the spray plate 5, and a plurality of nozzles 7 are fixedly connected to the lower end of the spray convex head 6, and the nozzles 7 are connected to the spray convex head 6, and the center of the spray plate 5 is provided with a plurality of nozzles 7, and the nozzles 7 are connected to the spray convex head 6. A first air duct 8 is provided, and the first air duct 8 is communicated with the air inlet; a diverter plate 9 is fixedly provided below the spray plate 5, and a second air duct is provided at the top of the diverter plate 9, and the second air duct is communicated with the first air duct 8; a plurality of diverter pipes 10 are provided below the diverter plate 9, and a spray port 11 is opened at the upper end of the diverter plate 9, the spray port 11, the spray convex head 6 and the diverter pipe 10 are all concentrically arranged, and the diameter of the spray convex head 6 and the spray port 11 are the same; a collecting component and an exhaust pipe 12 are fixedly connected below the diverter pipe 10, the exhaust pipe 12 is communicated with the inside of the collecting component, and the collecting component and the diverter pipe 10 are communicated.

[0034] When the flue gas is treated, the flue gas is input from the air inlet on the top of the water tank 3. The flue gas is input through the air inlet, transmitted to the second air duct 8 on the spray plate 5, and enters the diverter plate 9. At this time, the spray convex head 6 of the spray plate 5 is matched with the spray port 11 on the diverter pipe 10, so that the upper end of the diverter plate 9 does not leak. Then the nozzle 7 sprays the desulfurizer, and the flue gas entering the air inlet is diverted through the diverter plate 9, and then the desulfurizer is sprayed out through the nozzle 7, so that the treatment of the flue gas is more complete, and the treated flue gas is discharged through the exhaust pipe 12, thereby preventing incomplete treatment of the flue gas.

[0035] In this embodiment, the collecting component includes a collecting chamber 13, and a through hole 14 is provided at the upper end of the collecting chamber 13. The size, position and number of the through hole 14 are consistent with the diversion pipe 10; below the collecting chamber 13 is a waste chamber, and a material pipe 15 and a water filter port 16 are provided at the bottom of the waste chamber, and a filter plate 17 is provided on the water filter port 16.

[0036] By setting up the collecting chamber 13, the sprayed desulfurizer will flow down after treating the flue gas, and the waste liquid will be accompanied by some impurities and precipitates produced by the reaction. By setting up the material pipe 15 and the water filter port 16, the precipitate can be discharged through the material pipe 15, and the liquid will leak out through the filter plate 17, so as to separate the solid and liquid.

[0037] In this embodiment, preferably, the filter plate 17 is in a truncated cone shape, and a filter hole 18 is formed at the top of the filter plate 17 .

[0038] A filter hole 18 is provided at the top of the filter plate 17, and the solid will slide down from the side end of the truncated cone, preventing the solid from settling and accumulating on the filter hole 18, causing the filter plate 17 to be blocked and reducing the separation effect.

[0039] Preferably, the waste chamber is in the shape of an inverted cone.

[0040] By setting the waste chamber to be inverted cone-shaped, waste liquid can quickly gather at the bottom of the waste box.

[0041] On the basis of Example 1, the utility model provides a technical solution: preferably, a partition 19 is provided below the outlet of the exhaust pipe 12 in the collecting chamber 13, and a waste outlet is provided at the center of the partition 19.

[0042] In this embodiment, by providing the partition 19 , the partition 19 can block the gas discharged from the shunt pipe 10 to a certain extent, thereby preventing most of the discharged gas from overflowing from the collecting chamber 13 .

[0043] On the basis of Example 1, the utility model provides a technical solution: preferably, the filter plate 17 is slidably connected to the water filter port 16 .

[0044] In this embodiment, the filter plate 17 is slidably connected to the water filter port 16. Some small sediments and fertilizers are easy to block the water filter port 16. By setting the filter plate 17 slidably connected to the water filter port 16, when the water filter port 16 is blocked, the filter plate 17 can be slid out and cleaned.

[0045] On the basis of Example 1, the utility model provides a technical solution: preferably, a corrugated plate 20 is fixedly provided in the exhaust pipe 12 .

[0046] In this embodiment, because the temperature of the flue gas input from the air inlet pipe 4 is relatively high, the output gas will easily liquefy to form white mist. When the gas containing mist flows through the demister at a certain speed, due to the inertial impact of the gas, the mist collides with the corrugated plate 20 and the collected droplets are so large that the gravity generated by itself exceeds the combined force of the gas's rising force and the liquid's surface tension, and the droplets are separated from the surface of the corrugated plate 20. The multi-fold structure of the corrugated plate 20 increases the chance of mist being captured, and the mist that is not removed is captured at the next turn through the same action, and the repeated action greatly improves the demisting efficiency.

[0047] The following is a detailed description of the working principle of the kiln flue gas treatment equipment.

[0048] like Figure 1-5As shown, when the flue gas is treated, the flue gas is input from the air inlet on the top of the water tank 3, and the flue gas is input through the air inlet, transferred to the second air channel through the first air channel 8l on the spray plate 5, and enters the diverter plate 9. At this time, the spray convex head 6 of the spray plate 5 is matched with the spray port 11 on the diverter pipe 10, so that the upper end of the diverter plate 9 does not leak. Then the nozzle 7 sprays the desulfurizer, and the flue gas entering the air inlet is diverted through the diverter plate 9, and then the desulfurizer is sprayed out through the nozzle 7, so that the treatment of the flue gas is more complete, and the treated flue gas is discharged through the exhaust pipe 12 ; Prevent incomplete treatment of flue gas; the sprayed desulfurizer will flow down after treating the flue gas, and the waste liquid will be accompanied by some impurities and precipitates produced by the reaction. By setting the material pipe 15 and the water filter port 16, the precipitate can be discharged through the material pipe 15, and the liquid will leak out through the filter plate 17, so as to separate the solid and liquid; by setting the corrugated plate 20, the water vapor in the flue gas hits the corrugated plate 20 and is captured, and the droplets gather to form a water flow, which falls into the slurry pool due to gravity, realizing gas-liquid separation, so that the flue gas flowing through the demister meets the demisting requirements and is discharged.

[0049] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
