Description

Technical Field

[0001] This utility model relates to the field of sludge treatment technology, and in particular to a sludge injection gun for furnaces. Background Technology

[0002] Waste-to-energy plants require sludge to be injected into the incinerator for combustion. However, sludge is characterized by low fluidity and high viscosity, and it needs to be dispersed before entering the furnace. Therefore, there is a need for a sludge injection nozzle. Utility Model Content

[0003] This utility model solves the problems in related technologies and proposes a sludge injection gun for furnaces. A water inlet is provided in the sludge inlet pipe for backup water replenishment, which can be appropriately diluted with water according to the actual situation of the sludge. An auxiliary blowing port is provided on the side of the sludge outlet pipe near the sludge inlet pipe. The auxiliary blowing port is connected to compressed air. One cavity of the sludge outlet pipe is connected to the sludge inlet pipe and is used to carry sludge, while the other cavity is connected to the auxiliary blowing port and is used to carry air. After the sludge is sprayed out, it is dispersed by air, so that the sludge is dispersed as much as possible after entering the furnace, thereby improving the combustion efficiency.

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: a sludge injection gun for furnace, including a detachably connected sludge inlet pipe and a sludge outlet pipe, wherein the sludge inlet pipe is provided with a water inlet, the sludge outlet pipe is provided with an auxiliary blowing port, and the sludge outlet pipe has two cavities, one of which is connected to the sludge inlet pipe and the other cavity is connected to the auxiliary blowing port.

[0005] As a preferred embodiment, the sludge inlet pipe is a bent pipe with two ports, one of which is detachably connected to the sludge outlet pipe, and the other port is a sludge inlet.

[0006] As a preferred embodiment, both ends of the mud inlet pipe are provided with connecting flanges, and one end of the mud outlet pipe is also provided with a connecting flange. The mud inlet pipe and the mud outlet pipe are detachably connected by connecting flanges and bolts.

[0007] As a preferred embodiment, the mud inlet pipe is also provided with a main nozzle and a cleaning port, wherein the main nozzle is connected to compressed air and inserted into the inner cavity of the mud outlet pipe.

[0008] As a preferred embodiment, a temperature measuring port is also provided inside the mud inlet pipe.

[0009] As a preferred embodiment, the sludge outlet of the sludge discharge pipe has a conical structure.

[0010] As a preferred embodiment, there are at least two blowing ports.

[0011] As a preferred embodiment, the outer wall of the mud discharge pipe is provided with several reinforcing ribs.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: The sludge inlet pipe is equipped with a water inlet for backup water replenishment, allowing for appropriate dilution based on the actual condition of the sludge; the sludge outlet pipe is equipped with an auxiliary blowing port connected to compressed air. One cavity of the outlet pipe is connected to the inlet pipe for sludge flow, while the other cavity is connected to the auxiliary blowing port for air flow. After the sludge is sprayed out, it is dispersed by air, which provides both cooling and dispersion, thus maximizing the dispersion of the sludge upon entering the furnace and improving combustion efficiency; the inlet pipe is a curved pipe, saving more space compared to straight or right-angled pipes; the sludge outlet of the outlet pipe has a conical structure, facilitating rapid sludge discharge. Furthermore, the gradually narrowing conical structure reduces the risk of sludge adhesion and accumulation on the pipe wall. For high-viscosity or high-solids-content sludge, the conical design effectively prevents blockage through increased flow velocity and shear force; the outer wall of the outlet pipe is equipped with reinforcing ribs, which not only strengthen the pipe but also guide and position it.

Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0022] In the description of this utility model, it should be understood that the directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description.

[0025] like Figures 1 to 4 As shown, a sludge injection gun for furnace includes a detachably connected sludge inlet pipe 1 and sludge outlet pipe 2. To address the low fluidity and high viscosity of the sludge, a water inlet 3 is provided on the side of the sludge inlet pipe 1 near the sludge outlet pipe 2. The water inlet 3 is connected to a water source and a water pump and is used for backup water replenishment. Depending on the actual condition of the sludge, water can be added appropriately to dilute it before it enters the sludge outlet pipe 2. To ensure that the sludge disperses as much as possible after entering the furnace and improves combustion efficiency, an auxiliary blowing port 4 is provided on the sludge outlet pipe 2. The auxiliary blowing port 4 is connected to compressed air. The sludge outlet pipe 2 has two cavities, namely a first cavity 201 and a second cavity 202. The first cavity 201 is connected to the sludge inlet pipe 1 and is used to carry sludge, while the second cavity 202 is connected to the auxiliary blowing port 4 and is used to carry air. After the sludge is sprayed out, it is dispersed by air, which has both cooling and dispersing effects.

[0026] In one embodiment, the sludge inlet pipe 1 is a bent pipe, which saves more space compared to a straight pipe or a right-angle pipe. The sludge inlet pipe 1 has two ports, one of which is detachably connected to the sludge outlet pipe 2, and the other port is the sludge inlet 5.

[0027] In one embodiment, a connecting flange is provided at both ends of the sludge inlet pipe 1, and a connecting flange is also provided at one end of the sludge outlet pipe 2. The sludge inlet pipe 1 and the sludge outlet pipe 2 are detachably connected by the connecting flange and bolts. This detachable structure facilitates the disassembly and assembly of the two pipes and makes replacement convenient. In addition, the sludge inlet pipe 1 is also connected to the on-site pipeline through the connecting flange at the sludge inlet 5.

[0028] In one embodiment, the sludge inlet pipe 1 is also provided with a main nozzle 6 and a cleaning port 7. The main nozzle 6 is connected to compressed air and inserted into a suitable position in the inner cavity of the sludge outlet pipe 2 to squeeze out the sludge with air. It is only activated when the spray gun of this application is blocked. The cleaning port 7 is also connected to compressed air to improve the flowability of sludge in the sludge inlet 5.

[0029] In one embodiment, a temperature measuring port 8 is also provided inside the sludge inlet pipe 1 for inserting a thermometer or other temperature measuring device to monitor the temperature of the sludge.

[0030] In one embodiment, the sludge outlet 203 of the sludge outlet pipe 2 has a conical structure, which helps the sludge to be sprayed out quickly. Moreover, the conical structure reduces the risk of sludge adhesion and accumulation on the pipe wall through the gradually narrowing channel. For sludge with high viscosity or high solids content, the conical design can effectively prevent blockage by increasing the flow rate and shear force. The outlet end of the second cavity 202 forms a blowing outlet 204. The blowing outlet 204 is outside the sludge outlet 203. After the sludge is sprayed out from the sludge outlet 203, it is blown away by air through the blowing outlet 204.

[0031] In one embodiment, there are two blowing ports 4, which are symmetrically distributed to better disperse the sludge.

[0032] In one embodiment, the outer wall of the mud discharge pipe 2 is provided with several stiffening plates 9. The stiffening plates 9 are arranged vertically along the outer wall of the mud discharge pipe 2, which not only strengthen the pipe but also guide and position it.

[0033] The above are preferred embodiments of this utility model. Those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments described above. Any obvious improvements, substitutions or modifications made by those skilled in the art based on this utility model shall fall within the protection scope of this utility model.
