Description

Technical Field

[0001] This utility model relates to the field of waste incineration technology, and in particular to a lime slurry preparation device for a flue gas deacidification atomizer. Background Technology

[0002] Existing lime slurry preparation equipment involves adding calcium hydroxide and water to a storage tank, stirring, and then pumping the slurry to an atomizer. After atomization, the slurry is sprayed into the flue gas, effectively controlling acidic substances in the flue gas. However, existing slurry tanks discharge lime slurry from the bottom to the lime slurry pump, resulting in a large amount of sediment and impurities at the bottom. This causes the lime slurry to enter the atomizer and be atomized, which accelerates the wear of the atomizing disc, increases equipment maintenance costs, reduces the lifespan of the atomizing disc, and also increases environmental risks. Therefore, improvements are urgently needed. Utility Model Content

[0003] To address the shortcomings of the aforementioned technologies, this utility model provides a lime slurry preparation device for a flue gas deacidification atomizer, comprising a slurry storage tank, a lime slurry pump, and a transmission pipe. The lime slurry pump is connected to the inside of the slurry storage tank via the transmission pipe. The transmission pipe includes an outer pipe, an inner suction pipe, and a connecting flange. The end of the inner suction pipe is located in the middle of the slurry storage tank. A light filter device is provided at the end of the inner suction pipe. The light filter device includes a filter cylinder and an installation limiting mechanism. The filter cylinder includes a cylinder body, a cylinder bottom, and a sealing ring. The top of the cylinder body is detachably connected to the inner suction pipe via the installation limiting mechanism. The bottom of the cylinder body has an internal thread. A threaded connecting ring matching the shape and size of the cylinder body is provided on the cylinder bottom. The sealing ring is fitted onto the connecting ring. The cylinder bottom is detachably connected to the cylinder body via the connecting ring.

[0004] By adopting the above technical solution, the transmission pipe is divided into an outer pipe and an inner suction pipe, with the end of the inner suction pipe located in the middle of the slurry tank. A light filtration device, including a filter cylinder and a limiting mechanism, is installed on the inner suction pipe. When transferring lime slurry in the slurry tank, the inner suction pipe draws relatively clear lime slurry from the middle of the slurry tank. The drawn lime slurry first enters the filter cylinder from the top, flows through the bottom of the filter cylinder, and then enters the pipe from the inlet of the inner suction pipe. In this way, the lime slurry drawn in can minimize the carrying of impurities and sediments. At the same time, the light filtration device only adjusts the flow direction of the slurry and does not add components such as filter screens. Therefore, it does not require frequent maintenance, which improves the life of the atomizing disc and reduces environmental risks.

[0005] Further features of this invention: The installation limiting mechanism includes a limiting protrusion, an installation ring, several connecting rods, and several connecting hooks. The limiting protrusion is disposed on the outer circumferential surface of the inner suction tube, and the limiting protrusion has a groove that matches the connecting hook. The installation ring is connected to the inner wall of the cylinder through several connecting rods, and the several connecting hooks are disposed on the installation ring and rotate with the installation ring.

[0006] By adopting the above technical solution, since the installation limiting mechanism includes a limiting protrusion, an installation ring, several connecting rods, and several connecting hooks, the limiting protrusion is provided on the outer circumferential surface of the inner suction tube, and the limiting protrusion has a groove that matches the connecting hooks. The installation ring is connected to the inner wall of the cylinder through several connecting rods, and the several connecting hooks are provided on the installation ring and rotate with the installation ring. This allows the filter cartridge to be quickly and conveniently installed at the end of the inner suction tube. At the same time, since the inner suction tube is also detachable, it can be installed externally first and then installed internally, reducing the difficulty and tedium of maintenance.

[0007] A further feature of this invention is that a baffle is provided at the bottom of the cylinder to block impurities in the lime slurry, and the baffle is rotatably connected to the bottom of the cylinder.

[0008] By adopting the above technical solution, since a baffle for blocking impurities in lime slurry is provided at the bottom of the cylinder, and the baffle is rotatably connected to the bottom of the cylinder, the degree to which impurities and sediments at the bottom of the slurry tank float with the liquid flow during slurry transfer can be further reduced, and the content of impurities and sediments in the slurry entering the suction pipe can be further reduced.

[0009] A further feature of this invention is that an angle limiting plate for keeping the baffle tilted is provided at the bottom of the cylinder where it connects with the baffle.

[0010] By adopting the above technical solution, since an angle limiting plate for keeping the baffle tilted is provided at the bottom of the cylinder where it is connected to the baffle, the baffle can be kept tilted in the slurry tank, minimizing the accumulation of impurities and sediments on the surface of the baffle.

Detailed Implementation

[0016] like Figure 1-4 The illustrated lime slurry preparation equipment for a flue gas deacidification atomizer includes a slurry storage tank 1, a lime slurry pump 2, and a transmission pipe 3. The lime slurry pump is connected to the inside of the slurry storage tank through the transmission pipe. The transmission pipe includes an outer pipe 4, an inner suction pipe 5, and a connecting flange 6. The end of the inner suction pipe is located in the middle of the slurry storage tank. A light filter device 7 is provided at the end of the inner suction pipe. The light filter device includes a filter cylinder 8 and an installation limiting mechanism 9. The filter cylinder includes a cylinder body 10, a cylinder bottom 11, and a sealing ring 12. The top of the cylinder body is detachably connected to the inner suction pipe through the installation limiting mechanism. The bottom of the cylinder body is provided with an internal thread. A threaded connecting ring 13 matching the shape and size of the cylinder body is provided on the cylinder bottom. The sealing ring is fitted on the connecting ring. The cylinder bottom is detachably connected to the cylinder body through the connecting ring.

[0017] By dividing the transmission pipe into an external pipe and an internal suction pipe, with the end of the internal suction pipe located in the middle of the slurry tank, and then installing a light filtration device including a filter cylinder and a limiting mechanism on the internal suction pipe, when transferring lime slurry in the slurry tank, the internal suction pipe draws in the relatively clear lime slurry from the middle of the slurry tank. The drawn lime slurry first enters the filter cylinder from the top, flows through the bottom of the filter cylinder, and then enters the pipe from the inlet of the internal suction pipe. In this way, the lime slurry drawn in can minimize the carrying of impurities and sediments. At the same time, the light filtration device only adjusts the flow direction of the slurry and does not add components such as filter screens, so it does not require frequent maintenance, which improves the life of the atomizing disc and reduces environmental risks.

[0018] The installation limiting mechanism includes a limiting protrusion 14, an installation ring 15, several connecting rods 16, and several connecting hooks 17. The limiting protrusion is disposed on the outer circumferential surface of the inner suction tube, and the limiting protrusion is provided with a groove 18 that matches the connecting hook. The installation ring is connected to the inner wall of the cylinder through several connecting rods, and the several connecting hooks are disposed on the installation ring and rotate with the installation ring.

[0019] Since the installation limiting mechanism includes a limiting protrusion, an installation ring, several connecting rods, and several connecting hooks, the limiting protrusion is located on the outer circumferential surface of the inner suction tube, and the limiting protrusion has a groove that matches the connecting hooks. The installation ring is connected to the inner wall of the cylinder through several connecting rods, and the several connecting hooks are located on the installation ring and rotate with the installation ring. This allows the filter cartridge to be quickly and easily installed at the end of the inner suction tube. At the same time, since the inner suction tube is also detachable, it can be installed externally first and then installed internally, reducing the difficulty and tedium of maintenance.

[0020] The bottom of the cylinder is provided with a baffle 19 for blocking impurities in the lime slurry, and the baffle is rotatably connected to the bottom of the cylinder.

[0021] Because the bottom of the cylinder is equipped with a baffle to block impurities in the lime slurry, and the baffle is rotatably connected to the bottom of the cylinder, the baffle can further reduce the degree to which impurities and sediments at the bottom of the slurry tank float with the liquid flow when the slurry is transferred, and further reduce the content of impurities and sediments in the slurry entering the suction pipe.

[0022] An angle limiting plate 20 for keeping the baffle tilted is also provided on the bottom of the cylinder at the position where it connects with the baffle.

[0023] Because an angle limiting plate for keeping the baffle tilted is provided at the bottom of the cylinder where it connects with the baffle, the baffle can be kept tilted in the slurry tank, minimizing the accumulation of impurities and sediments on the baffle surface.
