Description

Technical Field

[0001] This utility model relates to the field of waste incineration technology, specifically to a waste incineration fly ash cooling, collection, and resource utilization treatment device. Background Technology

[0002] Waste incineration involves burning waste in an incinerator to release heat energy. Waste heat can be recovered for heating or power generation, and the purified flue gas is discharged. A small amount of residual residue is disposed of in landfills or used for other purposes. Simultaneously, fly ash generated during waste incineration is often collected and cooled for resource treatment. Cooling prevents further reactions or the generation of harmful substances at high temperatures. In the existing technology, authorized publication number CN 220453696... U proposed a cooling device for fly ash from waste incineration, comprising a body, an ash inlet pipe connected to one side of the body, a motor installed below the ash inlet pipe, a rotating shaft installed inside the body connected to the output end of the motor, conveying blades connected to the outside of the rotating shaft, a water inlet pipe connected through the top of the body, a spraying mechanism installed at the bottom of the water inlet pipe inside the body, a fan installed on one side of the water inlet pipe, a suction nozzle connected to the air inlet of the fan inside the body, an adsorption mechanism connected to the air outlet of the fan, and a discharge pipe connected to the bottom of the body. Although it can cool and collect fly ash, during the cooling and collection process, the flue gas is relatively concentrated in the flow, and the contact area between the flue gas and the coolant is small, affecting the comprehensiveness of fly ash cooling and collection. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the existing defects and provide a waste incineration fly ash cooling and collection resource utilization treatment device, which makes the waste incineration flue gas more dispersed in contact with the coolant on a horizontal plane, increases the contact area between the waste incineration flue gas and the coolant, and makes the cooling and collection of waste incineration flue gas more comprehensive, which can effectively solve the problems in the background technology.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a waste incineration fly ash cooling and collection resource utilization treatment device, including a frame, a cooling collection box at the upper end of the frame, nozzles at the upper end of the interior of the cooling collection box, an air inlet pipe at the air inlet on the left side of the cooling collection box, an air outlet pipe at the air outlet on the right side of the cooling collection box, and a flow guiding mechanism.

[0005] The flow guiding mechanism includes a dispersion shell, a cooling shell, and a converging shell. The dispersion shells are respectively disposed between the left and right inner walls of the cooling collection box. The longitudinally arranged dispersion shells are all connected to the air inlet pipe. The rear side of each dispersion shell is provided with a cooling shell. The cooling shells are connected to adjacent dispersion shells through multiple channels. The upper and lower ends of the cooling shells are open structures. The converging shell is disposed at the upper part of the interior of the cooling collection box. The right end of the converging shell is connected to the air outlet pipe. The upper end of each cooling shell is connected to the converging shell. Through the cooperation of the dispersion shell and the cooling shell, the waste incineration flue gas is more dispersed in contact with the coolant when placed horizontally. Compared with the direct contact between the waste incineration flue gas and the coolant, the contact area between the waste incineration flue gas and the coolant can be increased, making the cooling and collection of waste incineration flue gas more comprehensive, accurately avoiding the re-synthesis of dioxins in fly ash, and improving the resource utilization effect of waste incineration fly ash.

[0006] Furthermore, the flow guiding mechanism also includes baffles, which are respectively disposed between the front and rear inner walls of the cooling shell. The baffles in the same cooling shell are distributed laterally at equal intervals to separate the space inside the cooling shell and prevent the dispersed flue gas from mixing again.

[0007] Furthermore, the flow guiding mechanism also includes flow guiding inclined plates, which are respectively disposed between the upper and lower inner walls of the air inlet pipe. The flow guiding inclined plates are installed in conjunction with the dispersion shell to guide the flue gas into the interior of the dispersion shell evenly.

[0008] Furthermore, the flow guiding mechanism also includes dispersion holes and dispersion plates. The dispersion holes are respectively disposed on the rear side of the dispersion shell and are respectively connected to the air inlet holes on the front surface of the cooling shell. The dispersion plates are respectively disposed on the rear inner wall of the dispersion shell to guide the flue gas away from the dispersion shell through multiple channels.

[0009] Furthermore, all the dispersion holes are inclined holes, and all the dispersion plates are inclined plates. Both the dispersion holes and the dispersion plates gradually tilt to the right from front to back, making the guidance of flue gas smoother.

[0010] Furthermore, there is a gap between the front surface of the dispersion plate and the front inner wall of the dispersion shell. The gap between the front surface of the dispersion plate and the front inner wall of the dispersion shell decreases in a stepped manner from left to right within the same dispersion shell, so that the flue gas flows out of the dispersion hole evenly.

[0011] Furthermore, the upper surface of the manifold is provided with a water pipe, and a valve is connected in series at the water inlet end of the water pipe. All nozzles are connected to the water outlet end of the water pipe to control the spraying of coolant.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This waste incineration fly ash cooling, collection, and resource utilization treatment equipment has the following advantages:

[0013] By combining the dispersion shell and the cooling shell, the flue gas from waste incineration is more dispersed in contact with the coolant when placed horizontally. Compared with direct contact between the flue gas and the coolant, this increases the contact area between the flue gas and the coolant, making the cooling and collection of the flue gas more comprehensive, accurately preventing the resynthesis of dioxins in fly ash, and improving the resource utilization effect of waste incineration fly ash.

[0020] 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.

[0021] Please see Figure 1-5This embodiment provides a technical solution: a waste incineration fly ash cooling and collection resource utilization treatment device, including a frame 1, which provides support for the setting of waste incineration fly ash cooling and collection components. The upper end of the frame 1 is provided with a cooling collection box 2, which provides space for the setting of waste incineration fly ash cooling and collection components. The upper end of the cooling collection box 2 is provided with nozzles 8. Cooling liquid is sprayed from the nozzles 8 and comes into contact with the flue gas to quickly cool the flue gas, prevent the re-synthesis of dioxins in the fly ash, reduce the harmful substances in the fly ash, and perform resource utilization treatment of the fly ash, which is convenient for subsequent reuse of the fly ash. At the same time, the cooling liquid mixes with the fly ash in the flue gas to form ash residue. The ash residue falls downward to the lower end of the cooling collection box 2 under the action of gravity to collect the fly ash. An air inlet pipe 4 is provided at the air inlet on the left side of the cooling collection box 2 to facilitate the entry of flue gas into the cooling collection box 2. An air outlet pipe 3 is provided at the air outlet on the right side of the cooling collection box 2 to facilitate the discharge of the treated flue gas from the cooling collection box 2. It also includes a flow guiding mechanism 5.

[0022] The flow guiding mechanism 5 includes a dispersion shell 51, a cooling shell 52, and a confluence shell 53. The dispersion shells 51 are respectively disposed between the left and right inner walls of the cooling collection box 2. The longitudinally arranged dispersion shells 51 are all connected to the air inlet pipe 4. The rear side of each dispersion shell 51 is provided with a cooling shell 52. The cooling shell 52 is connected to the adjacent dispersion shell 51 through multiple channels. The upper and lower ends of the cooling shell 52 are open structures. The confluence shell 53 is disposed at the upper part of the interior of the cooling collection box 2. The right end of the confluence shell 53 is connected to the air outlet pipe 3. The upper ends of the cooling shells 52 are all connected to the confluence shell 53. After the flue gas enters the interior of the cooling collection box 2 through the air inlet pipe 4, it is sequentially processed inside the dispersion shell 51, cooling shell 52, and confluence shell 53. The flue gas flows and is finally discharged from the outlet pipe 3. The dispersion shell 51 makes the flue gas evenly distributed in the front-to-back direction. The multi-channel connection between the dispersion shell 51 and the cooling shell 52 makes the flue gas evenly distributed in the left-to-right direction, making the flue gas more dispersed in the horizontal direction, and making the contact between the flue gas and the coolant more uniform, thus improving the cooling and collection effect of fly ash. The flow guiding mechanism 5 also includes baffles 54, which are respectively set between the front and rear inner walls of the cooling shell 52. The baffles 54 are evenly distributed laterally within the same cooling shell 52 to separate the interior of the cooling shell 52 and prevent the dispersed flue gas from mixing. The flow guiding mechanism 5 also includes guide inclined plates 55, which are respectively set on the upper and lower inner walls of the inlet pipe 4. Between them, the guide plate 55 and the dispersion shell 51 are installed together to guide the flue gas, so that the flue gas enters the interior of the dispersion shell 51 evenly. The guide mechanism 5 also includes dispersion holes 56 and dispersion plates 57. The dispersion holes 56 are respectively set on the rear side of the dispersion shell 51 and are respectively connected to the air inlet holes on the front surface of the cooling shell 52. The dispersion plates 57 are respectively set on the rear inner wall of the dispersion shell 51. As the flue gas flows from left to right in the dispersion shell, the flue gas guided by the inclined dispersion plates 57 leaves through the dispersion holes 56 and enters the interior of the cooling shell 52. The dispersion holes 56 are all inclined holes, and the dispersion plates 57 are all inclined plates. The dispersion holes 56 and the dispersion plates 57 are all inclined plates. The dispersion holes 56 and the dispersion plates 57 are all gradually inclined to the right from front to back, so that the flue gas... The guidance is smoother. There is a gap between the front surface of the dispersion plate 57 and the front inner wall of the dispersion shell 51. The gap between the front surface of the dispersion plate 57 and the front inner wall of the dispersion shell 51 within the same dispersion shell 51 decreases in a stepped manner from left to right. The dispersion plate 57, whose length increases in a stepped manner from left to right, guides the flue gas multiple times, so that the flue gas leaves the dispersion hole 56 evenly and enters the interior of the cooling shell 52, making the flue gas more dispersed in the left and right directions. The upper surface of the confluence shell 53 is provided with a water pipe 6. The inlet end of the water pipe 6 is connected in series with a valve 7. The nozzles 8 are all connected to the outlet end of the water pipe 6 to control the spraying of coolant. The valve 7 can be a solenoid valve. The input end of the valve 7 is electrically connected to the output end of the external controller.

[0023] The working principle of the waste incineration fly ash cooling and collection resource utilization treatment equipment provided by this utility model is as follows: During the waste incineration process, the flue gas generated by incineration will enter the cooling collection box 2 through the air inlet pipe 4. Under the guidance of the guide plate 55, the flue gas will enter the dispersion shell 51 and be evenly distributed in the front-to-back direction. As the flue gas flows from left to right in the dispersion shell, the inclined dispersion plate 57 guides part of the flue gas to leave through the dispersion hole 56 and enter the cooling shell 52. The dispersion plate 57, whose length increases stepwise from left to right, guides the flue gas multiple times, so that the flue gas leaves through the dispersion hole 56 and enters the cooling shell 52 evenly. The flue gas is further dispersed in the left and right directions. Due to the closed lower end of the cooling collection box 2, the flue gas flows upward inside the cooling shell 52. At this time, the valve 7 is opened, and the coolant is sprayed out from the nozzle 8. As the coolant falls inside the cooling shell 52, it comes into contact with the rising flue gas and cools the flue gas. At the same time, the coolant mixes with the fly ash in the flue gas to form ash residue. The ash residue falls downward to the lower end of the cooling collection box 2 under the action of gravity to collect the fly ash, prevent the re-synthesis of dioxins in the fly ash, reduce the harmful substances in the fly ash, and carry out resource treatment of fly ash to facilitate subsequent reuse of fly ash. The treated flue gas is collected by the manifold shell 53 and discharged from the exhaust pipe 3.

[0024] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
