Description

Technical Field

[0001] The utility model relates to the technical field of hazardous waste coke inhibitor dosing, in particular to a portable coke inhibitor delivery device. Background Art

[0002] Hazardous waste often exhibits one or more hazardous properties, including corrosiveness, toxicity, flammability, reactivity, and infectivity, and exists in solid, semi-solid, or liquid forms. Therefore, incineration in rotary kilns is the most widely used and thorough method for decontamination. However, due to the diverse types and composition of hazardous waste, severe coking is a common operational issue in rotary kiln incineration at most domestic hazardous waste comprehensive disposal centers.

[0003] To reduce the coking rate in incinerators and improve the system's continuous operational stability, hazardous waste coke inhibitors are typically injected. These inhibitors are specialized coke inhibitors specifically designed for hazardous waste incinerators. When mixed with low-melting-point hazardous waste materials, the inhibitor raises their melting point through chelation or crystallization, preventing the formation of large network structures and coke lumps. Furthermore, the inhibitor forms a sandwich layer and a loose structure with the molten material, effectively inhibiting the formation of large coke lumps.

[0004] In the related art, the anti-coking agent is added from the inside of the feeding pipe to the inside of the dosing barrel. After the material is filled, the air compressor generates an air flow to blow into the inside of the dosing barrel, causing the anti-coking agent to spray out from the discharge pipe, thereby realizing the addition of hazardous waste anti-coking agent.

[0005] Regarding the relevant technologies mentioned above, the anti-scorch agent stored in the dosing barrel is also easily ineffective due to the combination with moisture in the natural air, and the air flow generated by the air compressor carries impurities such as water vapor and dust. The impurities are easily combined with the anti-scorch agent along with the air flow to form moist lumps, which block the discharge pipe of the dosing barrel. Therefore, there is a problem that the anti-scorch agent is easily moist and lumpy, and is difficult to store and transport.

[0006] In view of this, it is indeed necessary to provide a portable anti-coking agent delivery device to solve the above-mentioned technical solutions. Utility Model Content

The specific connection methods of each part adopt conventional means such as mature bolts, rivets, welding, etc. in the existing technology. The machinery, parts and equipment all adopt conventional models in the existing technology, and the circuit connection adopts the conventional connection method in the existing technology, which will not be described in detail here.

[0032] The following is combined with Figure 1 , further details of this application are given.

[0033] The present application provides a portable anti-coke agent delivery device, which adopts the following technical solutions:

[0034] The conveying device includes a dosing barrel 1, a movable barrel cover 2, a blanking pipe 3, a tee pipe 5, an air blowing pipe 6 and a spraying pipe 7. The dosing barrel 1 is in the shape of a hollow cylinder, and the dosing barrel 1 contains hazardous waste anti-coking agents used in hazardous waste incinerators. An interlayer 11 is provided inside the side wall of the dosing barrel 1, and a heating coil 4 is installed in a spiral manner inside the interlayer 11. The type of the heating coil 4 can be a conventional heat exchange tube or a high-frequency welded finned tube. The side wall of the dosing barrel 1 is fixedly connected with a first pipe 12 and a second pipe 13 in sequence from top to bottom. The first pipe 12 is connected to one end of the heating coil 4. On the incineration line of hazardous waste, the steam generated in the waste heat boiler is passed into the first pipe 12. The second pipe 13 is connected to the other end of the heating coil 4. The second pipe 13 is used to discharge the steam in the heating coil 4. The first pipe 12, the heating coil 4 and the second pipe 13 constitute the heating unit of the dosing barrel 1. Steam enters from the first pipe 12, flows through the heating coil 4 and is discharged from the second pipe 13. During the flow, the steam heats the side wall of the dosing barrel 1 through the heating coil 4, so that the water vapor in the dosing barrel 1 evaporates quickly, maintaining the environment in the heating barrel dry, avoiding the anti-scorch agent from agglomerating during storage, and helping to extend the shelf life of the anti-scorch agent.

[0035] The movable barrel cover 2 is installed on the top of the dosing barrel 1. One side of the movable barrel cover 2 is hinged to the top edge of the dosing barrel 1. The movable barrel cover 2 can prevent debris from falling into the barrel. The bottom end of the dosing barrel 1 is conical, and the blanking pipe 3 is vertically welded to the bottom center of the dosing barrel 1. The anti-coking agent is put into the incinerator through the blanking pipe 3. In actual production, in order to avoid the bridging and agglomeration of the anti-coking agent during the discharge process, the length of the blanking pipe 3 is designed to select the minimum length that meets the actual application. In this embodiment, the length of the blanking pipe 3 is 5 cm. In other embodiments, the length of the blanking pipe 3 is adaptively designed according to the size of the dosing barrel 1 and the agent addition requirements.

[0036] The tee pipe 5 is installed at the end of the blanking pipe 3 away from the dosing barrel 1. The tee pipe 5 is a reducing tee, including a main pipe and two branch pipes, wherein the axes of the two branch pipes are located on the same straight line, and the axes of the branch pipes are perpendicular to the axis of the main pipe. The main pipe of the tee pipe 5 is vertically threadedly connected to the bottom end of the blanking pipe 3, which is convenient for timely unblocking of the blanking pipe 3.

[0037] The air blowing pipe 6 is installed on the branch pipe at one end of the tee pipe 5. The air blowing pipe 6 is connected to the public auxiliary system of the incineration line, and the compressed air of the public auxiliary system is poured into the tee pipe 5. A filter 61 is also installed in the air blowing pipe 6 to filter impurities in the compressed air. The filter 61 can be a gas source treatment two-piece or a gas source treatment three-piece. Specifically, the gas source treatment two-piece integrates the air filter 61 and the pressure reducing valve into one unit, and the structural design is more compact, the component life is longer, and the maintenance cost is lower; the gas source treatment three-piece integrates the three gas source treatment components of the air filter 61, the pressure reducing valve and the oil mist collector into one unit, which can effectively remove impurities such as solid particles, liquid droplets and oil mist in the compressed air, ensuring that a clean, stable and appropriate power source is provided for the conveying device, thereby improving the working efficiency and maintainability of the system. The gas source two-piece is selected in this embodiment.

[0038] The injection pipe 7 is mounted on the branch pipe at the other end of the tee pipe 5 and is coaxial with the air blowing pipe 6. The coke inhibitor falling from the blanking pipe 3 is loosened by the compressed air in the air blowing pipe 6 and is then carried by the compressed air through the injection pipe 7 and released into the corresponding incinerator.

[0039] In a preferred embodiment of the present application, a drain valve 131 and a bypass pipe 14 are connected in parallel at the end of the second pipe 13 away from the dosing barrel 1. A first shut-off valve 132 is installed at each end of the drain valve 131, and a second shut-off valve 141 is installed on the bypass pipe 14. When steam is discharged from the second pipe 13, the two first shut-off valves 132 are opened and the second shut-off valve 141 is closed, allowing the steam to flow into the drain valve 131 and condense. The drain valve 131 then discharges the condensed water, which is then recycled, thereby improving resource utilization and reducing operating costs. If the drain valve 131 malfunctions, the two first shut-off valves 132 are closed and the second shut-off valve 141 is opened, allowing the steam to be discharged through the bypass pipe 14, maintaining the normal operation of the entire device. The drain valve 131 can also be removed from between the two first shut-off valves 132, making it easier to inspect and maintain the drain valve 131.

[0040] In a preferred embodiment of the present application, the end of the injection pipe 7 away from the tee pipe 5 is threadedly connected to a Y-type tube 71, and the end of the Y-type tube 71 away from the injection pipe 7 is integrally formed and connected to two pipelines. The angle between the two pipelines is an acute angle, and a flow control valve 72 is installed on each pipeline. The flow control valve 72 is used to adjust the output of the anti-coking agent at the end of the Y-type tube 71. The flow control valve 72 can be a ball valve, a stop valve, a butterfly valve, etc. On the one hand, one pipeline is put into use and the other pipeline is used as a backup. When a pipeline in use fails, the backup pipeline is switched to ensure the stability of the injection of the anti-coking agent; on the other hand, the two pipelines correspond to different incinerators respectively, and the amount of anti-coking agent injected into each incinerator is controlled by the flow control valve 72, thereby improving the adaptability of the device and meeting the amount of anti-coking agent injected under different working conditions.

[0041] Furthermore, the two pipes at one end of the Y-shaped tube 71 away from the blowing pipe 7 are integrally formed with a quick-connect interface 73, which is a threaded interface. The quick-connect interface 73 can be connected to pipes of various different materials, thereby improving the adaptability and connection efficiency of the device and other equipment.

[0042] In a preferred embodiment of the present application, a stirring blade 8 is rotatably installed at one end of the blanking pipe 3 close to the dosing barrel 1. The stirring blade 8 is spiral-shaped and is driven by a servo motor. The stirring blade 8 physically breaks up the anti-coking agent entering the blanking pipe 3, making the anti-coking agent looser and preventing the material from clogging the pipe mouth of the blanking pipe 3, thereby making the anti-coking agent conveyed smoother.

[0043] Furthermore, a lifting cylinder 81 is fixedly mounted on the inner wall of the dosing barrel 1, with the telescopic rod of the lifting cylinder 81 facing the blanking pipe 3. A servo motor is mounted on the telescopic rod of the lifting cylinder 81, and the servo motor drives the stirring blade 8 to rotate. The lifting cylinder 81 drives the stirring blade 8 to move up and down within the blanking pipe 3, improving the effect of the stirring blade 8 on the scorch inhibitor, making the scorch inhibitor more uniform and loose, and facilitating smoother entry of the scorch inhibitor into the blanking pipe 3.

[0044] In a preferred embodiment of the present application, the outer circumference of the first pipe 12 and the second pipe 13 are wrapped with an insulation layer. The insulation layer is made of aluminum silicate wool or aluminum silicate blanket and is wrapped with aluminum foil. The outer temperature of the insulation layer is lower than 40°C, which can reduce the risk of burns to operators and improve the safety of device operation.

[0045] In a preferred embodiment of the present application, four support legs 9 are installed around the bottom end of the medicine-dosing barrel 1. The support legs 9 are four cylindrical support bodies. The four support legs 9 are connected to the four sides of the medicine-dosing barrel 1 and serve as the main supporting components for the medicine-dosing barrel 1 to stand, thereby improving the stability of the medicine-dosing barrel 1. The bottoms of the support legs 9 are also installed with non-slip pads 91, which can increase the friction between the support legs 9 and the ground, further improving the stability of the medicine-dosing barrel 1.

[0046] The experimental principle of the embodiment of the present application is as follows: when it is necessary to add a coke-retarding agent to the incinerator, the movable barrel cover 2 is opened, and the coke-retarding agent is manually poured into the inside of the dosing barrel 1. After the agent is filled, the movable barrel cover 2 is closed, steam is introduced into the first pipe 12, the drain valve 131 is put into use, the bypass line is closed, and the steam flows through the heating coil 4 to exchange heat with the inside of the dosing barrel 1, continuously increasing the temperature of the coke-retarding agent inside the dosing barrel 1, thereby making the agent powder looser. The blowing pipe 6 is connected to the compressed air station of the public auxiliary system, and the blowing pipe 6 is screened by the filter 61 to introduce clean and dry compressed air. The quick-connect interface 73 of the Y-tube 71 is connected to the hose, and the flow control valve 72 is adjusted to an appropriate opening. The coke-retarding agent enters the tee pipe 5 from the blanking pipe 3, is mixed with the compressed air in the tee pipe 5, and is introduced into the Y-tube 71, and finally added to the incinerator. This device can not only keep the anti-scorch agent stored in the dosing barrel 1 dry and loose, but also make it easy to transport the anti-scorch agent, solving the problem of easy moisture and agglomeration during the agent addition and storage process. In addition, this device uses the steam of the waste heat boiler in the incineration line as a heat source, and recovers the condensed water therein. At the same time, it uses the compressed air produced by the public auxiliary system during normal production of the incineration line as the gas source, making full use of the gas circulation of the incineration line itself, thereby reducing the cost of use. In addition, the overall device is small in size, easy to operate, low in maintenance cost, easy to disassemble and transport, and can meet the use requirements of different working conditions.
