Description

Technical field:

[0001] The utility model relates to the production and manufacturing field of silicon-manganese alloy, in particular to a silicon-manganese alloy smelting tail gas washing tower. Background technology:

[0002] Silicon manganese alloy is an alloy composed of manganese, silicon, iron, a small amount of carbon and other elements. It is a ferroalloy with a wide range of uses and a large output. Manganese silicon alloy is a commonly used composite deoxidizer in steelmaking, and a reducing agent in the production of medium and low carbon ferromanganese and the production of metallic manganese by electrosilicon thermal method.

[0003] Due to the complex composition of silicon manganese tail gas, there are still fine dust particles in the gas after purification. Generally, the purification outlet temperature is between 100℃ and 300℃. Under this temperature condition, the tar is in gaseous state. After passing through pipelines and other facilities, the temperature gradually drops and it becomes liquid, resulting in blockage of the gas supply pipeline or tar blockage in the gas tank. When the amount of tar is large, it will also have a great impact on the service life of the inner membrane of the gas tank. When the dust content is high, it will have a great impact on the use of gas for power generation at the back end.

[0004] In order to solve the above problems, a scrubber capable of reducing the amount of tar and dust is proposed. Utility model content:

[0005] The utility model aims to provide a silicon-manganese alloy smelting tail gas washing tower.

[0006] The utility model is implemented by the following technical solutions:

[0007] A silicon-manganese alloy smelting tail gas scrubber comprises a scrubber, wherein two groups of guide plates and spiral water sprayers are arranged in the scrubber, wherein the spiral water sprayers in each group are arranged above the guide plates, wherein the spiral water sprayers are composed of a circular pipe and a plurality of nozzles, wherein a connecting pipe is arranged below the circular pipe, wherein fixing parts are respectively fixedly connected to both sides of the connecting pipe, wherein the fixing parts are provided with through holes, wherein a cover body is sleeved on the connecting pipe, wherein the cover body is cylindrical, wherein two cavities are arranged in the cover body, wherein a T-hook is slidably connected in each cavity, wherein the top end of each T-hook passes through the cavity and is slidably connected thereto, wherein the top end of each T-hook is hooked in the corresponding through hole of the fixing part, wherein a spring is sleeved on the T-hook, and wherein the spring is arranged in the cavity.

[0008] Preferably, a rotating ring is rotatably connected in the cover body, a nozzle is fixedly connected to the bottom end of the rotating ring, and a cleaning rod is inserted into the bottom end of the cover body.

[0009] Preferably, a sealing assembly is provided at the top of the cover body.

[0010] The advantages of the utility model are as follows: when installing, the two T-hooks are directly pulled out so that the top of the cover body is also directly put on the connecting pipe, so that it can be installed and disassembled very conveniently, and the operation is simple and convenient. When repairing and replacing damaged nozzles, it can improve work efficiency and save time. The output end of the nozzle can be simply cleaned with a cleaning rod, which can effectively increase the service life of the nozzle and reduce the blockage rate. Description of the drawings:

[0011] Figure 1 It is a schematic diagram of the structure of the utility model;

[0012] Figure 2 This utility model Figure 1 Schematic diagram of the structure of the spiral water sprinkler.

[0013] In the figure: a scrubber 1, a guide plate 2, a spiral water sprayer 3, a fixing member 4, a cover 5, a cavity 6, a T-hook 7, a spring 8, a nozzle 9, a rotating ring 10, and a cleaning rod 11. Specific implementation method:

[0014] like Figure 1 to Figure 2 As shown, a silicon-manganese alloy smelting tail gas scrubber includes a scrubber 1, wherein two groups of guide plates 2 and spiral water sprayers 3 are arranged in the scrubber 1, wherein the spiral water sprayers 3 in each group are arranged above the guide plates 2, wherein the spiral water sprayers 3 are composed of a circular pipe and a plurality of nozzles 9, wherein a connecting pipe is arranged below the circular pipe, wherein fixing members 4 are fixedly connected to both sides of the connecting pipe, wherein the fixing members 4 are provided with through holes, wherein a cover body 5 is sleeved on the connecting pipe, wherein the cover body 5 is cylindrical, wherein two cavities 6 are arranged in the cover body 5, wherein each cavity 6 is slidably connected to a T-shaped hook 7, wherein the top of each T-shaped hook 7 is It passes through the cavity 6 and is slidably connected thereto, the top end of each T-hook 7 is hooked in the corresponding through hole of the fixing member 4, and a spring 8 is sleeved on the T-hook 7, and the spring 8 is arranged in the cavity 6. During installation, the two T-hooks 7 are directly pulled out, so that the spring 8 is compressed by force, so that the two T-hooks 7 can be smoothly hooked on the fixing member 4, so that the top end of the cover body 5 is also directly sleeved on the connecting pipe, so that it can be installed and disassembled very conveniently, the operation is simple and convenient, and when repairing and replacing damaged nozzles 9, it can improve work efficiency and save time.

[0015] The gas direction of the scrubbing tower 1 is low-in and high-out. The gas enters the tower and moves upward. The gas velocity is reduced when passing through the first layer of guide plate 2 in the middle. 24 groups of spiral water sprayers 3 are set 1 meter above the guide plate 2. The gas continues to pass through the second layer of guide plate 2 upward. The second layer of guide plate 2 can further reduce the gas velocity. 24 groups of spiral water sprayers 3 are added 1 meter above the second layer. The spiral water sprayers 3 can atomize the water under pressure through the water pump. The gas can be quickly cooled during the passage of the gas, so that the gaseous tar becomes liquid. The dust particles contained in the gas increase their specific gravity after mixing with water, and fall to the bottom of the tower after mixing with water tar. They are washed into the sedimentation tank by water flow. The sedimentation tank is divided into 6 sections. After each section, it is deposited in the water reservoir. The water returns to the tower for spraying through the water pump, thereby achieving the recycling of water resources.

[0016] The guide plate 2 in the scrubber 1 is made of polypropylene material, which has good acid and alkali resistance and corrosion resistance. A spray device is set inside the tower to flush and absorb the gas by spraying liquid, so as to achieve full contact between the gas and the liquid. This can improve the scrubbing effect, improve the gas purification and liquid recycling rate, can handle corrosive gases and liquids, and can effectively remove harmful substances and particulate matter in the gas, such as acid mist, alkali mist, odorous gas, etc. According to different process requirements, different fillers and spray liquids can be selected to achieve better gas purification effects. The operating energy consumption of the scrubber is relatively low, and the purpose of energy saving and emission reduction can be achieved by adjusting parameters such as liquid flow and gas flow rate.

[0017] A rotating ring 10 is rotatably connected inside the cover body 5, and a nozzle 9 is fixedly connected to the bottom end of the rotating ring 10. A cleaning rod 11 is inserted into the bottom end of the cover body 5. When water flows into the nozzle 9, since the rotating ring 10 is rotatably connected to the cover body 5, the operator can manually rotate it during each maintenance process. In this way, the output end of the nozzle 9 can be simply cleaned using the cleaning rod 11, which can effectively increase the service life of the nozzle 9 and reduce the blockage rate.

[0018] A sealing component is provided at the top of the cover body 5 to play a sealing role and prevent water seepage.

[0019] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
