Description

Technical Field

[0001] The present application relates to the technical field of acetylene production, and in particular to an acetylene purifier and acetylene production equipment. Background Art

[0002] The production of acetylene black requires large quantities of acetylene gas. Currently, industrial production generally uses the calcium carbide process. Calcium carbide produces crude acetylene gas in a generator. After passing through a sodium hypochlorite purification tower and a sodium hydroxide neutralization tower to remove sulfur and phosphorus impurities, other impurities are added to the acetylene gas. After passing through a purifier, the impurities are removed, resulting in a relatively pure acetylene gas for use in acetylene black production, thereby improving the quality of the acetylene black. However, impurities in the acetylene gas can easily clog the filter element of the purifier, reducing its service life. Furthermore, filter element replacement requires technicians to use lifting equipment, which is difficult and labor-intensive. Furthermore, filter elements are expensive, and frequent replacement increases operating costs. Utility Model Content

[0005] Optionally, the freezing coil has a water inlet and a water outlet, and the water inlet is located above the water outlet.

[0006] The beneficial effect of this technical solution is that: in this way, a countercurrent is formed between the low-temperature water in the refrigeration coil and the mixed gas in the shell, thereby improving the cooling efficiency of the water in the mixed gas and further improving the purification efficiency of the refrigeration coil for the mixed gas.

[0007] Optionally, the acetylene purifier provided in the present application further includes a magnetic component, which is installed outside the filter element.

[0008] The beneficial effect of this technical solution is that, before the mixed gas enters the filter element, it first flows through the magnetic element, and the magnetic element will absorb the magnetic substances in the mixed gas, so that the mixed gas is purified before entering the filter element, reducing the purification burden of the filter element, extending the filter element cleaning and replacement cycle, saving labor and machinery, and also saving costs; and, since the magnetic element is added to filter the mixed gas first, the acetylene gas finally sent out from the purifier is cleaner.

[0009] Optionally, the magnetic member is in a rod shape, and the axial direction of the magnetic member is parallel to the axial direction of the filter element.

[0010] The beneficial effect of this technical solution is that the rod-shaped magnetic member allows the mixed gas to quickly surround the magnetic member and fully contact the magnetic member before entering the filter element, thereby achieving the purpose of efficiently purifying the mixed gas.

[0011] Optionally, the acetylene purifier provided in the present application includes a plurality of the magnetic members, and the magnetic members are evenly distributed in the circumferential direction of the filter element.

[0012] The beneficial effect of this technical solution is that it facilitates each magnetic component to contact the mixed gas before entering the filter element from multiple positions, multiple angles and multiple locations, thereby increasing the amount of mixed gas that can be purified by the magnetic component per unit time and improving the purification efficiency.

[0013] Optionally, the acetylene purifier provided in the present application further includes a spray pipe, and the filter element is sleeved on the spray pipe.

[0014] The beneficial effect of this technical solution is that: in this way, water can be intermittently sprayed into the filter element through the spray pipe, so that impurities adsorbed on the filter element are removed by the water spray, and the filter element is cleaned, thereby extending the filter element cleaning and replacement cycle, saving labor and machinery, and also saving costs. At the same time, since the filter element can be periodically cleaned through the spray pipe, the acetylene gas finally delivered from the purifier is cleaner.

[0015] Optionally, the spray pipe includes a connecting portion and a spraying portion distributed in the axial direction of the spray pipe, the connecting portion is used to connect with an external production water pipe, the spraying portion is located in the filter element, the spray pipe is coaxially arranged with the filter element, the length of the spraying portion is smaller than the length of the filter element, and a plurality of spray holes are evenly distributed on the spraying portion.

[0016] The beneficial effect of this technical solution is that the water sprayed from the spray pipe can clean the filter element in a larger range, thereby improving the cleaning efficiency and cleaning effect of the filter element.

[0017] Optionally, the acetylene purifier provided in the present application includes a plurality of the filter elements, and there are a plurality of the spray pipes, and the spray parts of the respective spray pipes are disposed in the respective filter elements in a one-to-one correspondence.

[0023] The acetylene purifier and acetylene production equipment provided by the present application are such that after the mixed gas of acetylene and impurities enters the shell from the gas inlet, it will flow through the refrigeration coil, the filter element and the gas outlet in sequence. When the mixed gas flows through the refrigeration coil, the mixed gas contacts the low-temperature refrigeration coil, and the moisture in the mixed gas is condensed and drips downward. At the same time, the impurities dissolved in the water in the mixed gas also drip downward together with the moisture. Therefore, before the mixed gas enters the filter element, the mixed gas is first purified, reducing the burden of the filter element in filtering impurities in the mixed gas, extending the filter element cleaning and replacement cycle, saving labor and machinery, and also saving costs. Moreover, since the refrigeration coil is added to filter the mixed gas first, the acetylene gas finally sent out from the purifier is cleaner.

[0038] The following will clearly and completely describe the technical solution of this application in conjunction with the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of this application.

[0040] In the description of this application, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0041] like Figure 1 and Figure 2As shown, the present application provides an acetylene purifier, comprising a shell 13 and a filter element 12 installed in the shell 13. The acetylene purifier also includes a refrigeration coil 10 arranged in the shell 13, and the refrigeration coil 10 is located below the filter element 12. A gas inlet 04 and a gas outlet 02 are formed on the shell 13, and the gas outlet 02 is located above the filter element 12, so that the gas entering the shell 13 from the gas inlet 04 flows through the refrigeration coil 10, the filter element 12 and the gas outlet 02 in sequence.

[0042] In the acetylene purifier provided by the present application, after the mixed gas of acetylene and impurities enters the shell 13 from the gas inlet 04, it will flow through the refrigeration coil 10, the filter element 12 and the gas outlet 02 in sequence. When the mixed gas flows through the refrigeration coil 10, the mixed gas contacts the low-temperature refrigeration coil 10, and the moisture in the mixed gas is condensed and drips downward. At the same time, the impurities dissolved in the water in the mixed gas also drip downward together with the moisture. Before the mixed gas enters the filter element 12, the mixed gas is first preliminarily purified (for example, it can be preliminarily purified using an acid tower, an alkali tower and a neutralization tower in sequence), reducing the burden of the filter element 12 in filtering impurities in the mixed gas, extending the cleaning and replacement cycle of the filter element 12, saving labor and machinery, and also saving costs. In addition, since the refrigeration coil 10 is added to first preliminarily remove water and impurities from the gas, the acetylene gas finally sent out from the purifier is cleaner.

[0043] Optionally, the refrigeration coil 10 has a water inlet 03 and a water outlet 05, with the water inlet 03 located above the water outlet 05. This creates a countercurrent between the low-temperature water in the refrigeration coil 10 and the mixed gas in the housing 13, improving the cooling efficiency of the water in the mixed gas and, in turn, the purification efficiency of the mixed gas by the refrigeration coil 10. In this embodiment of the present application, the gas inlet 04 can be located below the refrigeration coil 10, or the gas inlet can be located in the lower middle portion of the refrigeration coil 10.

[0044] Optionally, the acetylene purifier provided in the embodiment of the present application further includes a magnetic member 11, which is mounted outside the filter element 12. Thus, before the mixed gas enters the filter element 12, it first flows through the magnetic member 11. The magnetic member 11 absorbs magnetic substances in the mixed gas, purifying the mixed gas before entering the filter element 12. This reduces the purification burden of the filter element 12, extends the cleaning and replacement cycle of the filter element 12, saves labor and machinery, and also saves costs. Furthermore, since the addition of the magnetic member 11 first filters the mixed gas to remove magnetic substances, the acetylene gas ultimately delivered from the purifier is cleaner.

[0045] Optionally, the magnetic member 11 is in a rod shape, and the axial direction of the magnetic member 11 is parallel to the axial direction of the filter element 12. The rod-shaped magnetic member 11 facilitates the mixed gas to quickly surround the magnetic member 11 before entering the filter element 12 and fully contact the magnetic member 11, thereby achieving the purpose of efficiently purifying the mixed gas.

[0046] Optionally, the acetylene purifier provided in the embodiment of the present application includes a plurality of magnetic members 11, each of which is evenly distributed around the circumference of the filter element 12. This allows each magnetic member 11 to contact the mixed gas before entering the filter element 12 from multiple positions, multiple angles, and multiple locations, thereby increasing the amount of mixed gas that can be purified by the magnetic members 11 per unit time and improving purification efficiency.

[0047] Optionally, the acetylene purifier provided in the embodiment of the present application further includes a spray pipe 14, and the filter element 12 is mounted on the spray pipe 14. In this way, water can be intermittently sprayed into the filter element 12 through the spray pipe 14, so that impurities adsorbed on the filter element 12 are removed by the water spray, thereby cleaning the filter element 12. This extends the cleaning and replacement cycle of the filter element 12, saves labor and machinery, and also saves costs. At the same time, since the filter element 12 can be periodically cleaned through the spray pipe 14, the acetylene gas ultimately delivered from the purifier is cleaner.

[0048] Optionally, the spray pipe 14 includes a connecting portion 16 and a spray portion 17 distributed in the axial direction of the spray pipe 14, the connecting portion 16 is used to communicate with the external production water pipe 01, the spray portion 17 is located in the filter element 12, the spray pipe 14 is coaxially arranged with the filter element 12, the length of the spray portion 17 is less than the length of the filter element 12, and a plurality of spray holes 18 are evenly distributed on the spray portion 17. In this way, the water sprayed from the spray pipe 14 can clean the filter element 12 over a larger range, thereby improving the cleaning efficiency and cleaning effect of the filter element 12. In the embodiment of the present application, multiple rows of spray holes 18 are distributed in the circumferential direction of the spray portion 17, and the number of spray holes 18 in each row is 5 to 15. Preferably, four rows of spray holes 18 are distributed in the circumferential direction of the spray portion 17, and the number of spray holes 18 in each row is 10.

[0049] Optionally, the acetylene purifier provided in the embodiment of the present application includes a plurality of filter elements 12, a plurality of spray pipes 14, and the spray parts 17 of the spray pipes 14 are disposed in correspondence with each other in the filter elements 12. This allows each filter element 12 to be cleaned regularly.

[0050] Optionally, the acetylene purifier provided in this embodiment includes a drain pipe 06 and a controller, as well as a drain valve 08 and a liquid level gauge 09, both of which are communicatively connected to the controller. The drain valve 08 is mounted on the drain pipe 06, and the liquid level gauge 09 is mounted on the housing 13. The drain pipe 06 communicates with the housing 13 at its bottom end. Thus, when the water level in the housing 13 reaches the height monitored by the liquid level gauge 09, the controller controls the drain valve 08 to open, draining the water in the housing 13 through the water distribution pipe to the ditch 07, thereby preventing large amounts of water from accumulating in the housing 13. In other words, the liquid level gauge 09 and the drain valve 08 are interlocked, preventing the liquid level in the purifier from rising.

[0051] Another aspect of the present application provides an acetylene production device, including the acetylene purifier provided in the embodiments of the present application.

[0052] The acetylene production equipment provided in the present application adopts the acetylene purifier provided in the present application. After the mixed gas of acetylene and impurities enters the shell 13 from the gas inlet 04, it will flow through the refrigeration coil 10, the filter element 12 and the gas outlet 02 in sequence. When the mixed gas flows through the refrigeration coil 10, the mixed gas contacts the low-temperature refrigeration coil 10, and the moisture in the mixed gas is condensed and drips downward. At the same time, the impurities dissolved in the water in the mixed gas also drip downward together with the moisture. Then, before the mixed gas enters the filter element 12, the mixed gas is first purified, reducing the burden of the filter element 12 in filtering impurities in the mixed gas, extending the cleaning and replacement cycle of the filter element 12, saving labor and machinery, and also saving costs; and, since the refrigeration coil 10 is added to filter the mixed gas first, the acetylene gas finally sent out from the purifier is cleaner.

[0053] In addition, water can be intermittently sprayed into the filter element 12 through the spray pipe 14, so that impurities adsorbed on the filter element 12 are removed by the water spray, thereby cleaning the filter element 12, thereby extending the cleaning and replacement cycle of the filter element 12, saving labor and machinery, and also saving costs. At the same time, since the filter element 12 can be periodically cleaned through the spray pipe 14, the acetylene gas finally sent out from the purifier is cleaner.

[0054] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some or all of the technical features therein. These modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present application.
