Description

Technical Field

[0001] The utility model relates to the technical field of dust removal and vulcanization in sintering plants, and particularly relates to a dust removal and vulcanization gas source pipe for sintering plants with convenient connection. Background Technique

[0002] In a sintering plant, the dust removal and vulcanization gas source pipe plays an important role, mainly used for collecting and transporting dust removal ash to ensure the air quality inside the plant and reduce environmental pollution.

[0003] Flue gas desulfurization and dust removal are two different processes. Flue gas desulfurization refers to the removal of sulfur oxides (SO2 and SO3) from flue gas or other industrial waste gases, while flue gas dust removal refers to the removal of particulate matter in the flue gas. During the dust removal process, the dust removal filter screen is prone to blockage, and at the same time, the dust removal device located in the flue gas pipeline is not easy to disassemble, making daily maintenance more troublesome. Therefore, we propose a dust removal and vulcanization gas source pipe for sintering plants with convenient connection to solve the above problems. Content of the Utility Model

[0004] The purpose of the utility model is to solve the shortcomings in the prior art, and propose a dust removal and vulcanization gas source pipe for sintering plants with convenient connection.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A dust removal and vulcanization gas source pipe for sintering plants with convenient connection includes an elbow pipe and a vertical pipe. A dust removal mechanism is installed inside the elbow pipe, and a desulfurization mechanism is installed inside the vertical pipe; the dust removal mechanism includes a ring frame and a pressure equalizing ring pipe. A filter screen is fixedly installed inside the ring frame, the pressure equalizing ring pipe is fixedly installed on the inner wall of the elbow pipe, a number of jet orifices are evenly distributed on the pressure equalizing ring pipe, a high-pressure inlet pipe is connected and installed on the pressure equalizing ring pipe, the high-pressure inlet pipe extends through to the outside of the elbow pipe, a first connection flange is fixedly installed at the left end of the elbow pipe, a ring groove is opened at the left end of the elbow pipe, and the ring frame is screwed and installed inside the ring groove.

[0007] Preferably, the elbow pipe includes a bent section, a horizontal section and a vertical section, and a second connection flange is fixedly installed at the upper end of the vertical section.

[0008] Preferably, a third connection flange is fixedly installed at the lower end of the vertical pipe, and the third connection flange is screwed to the second connection flange.

[0009] Preferably, a drain pipe is connected and installed at the lower end of the horizontal section, and a solenoid valve gate is installed on the drain pipe.

[0010] Preferably, the jet orifices face the filter screen.

[0011] Preferably, the desulfurization mechanism includes a number of annular pipes. Limestone solution inlet pipes and cleaning water inlet pipes are connected and installed on both sides of the annular pipes. A connecting main pipe is connected between the several annular pipes. Spray heads are evenly installed on the annular pipes and the connecting main pipe.

[0012] Preferably, the spray head is an atomizing spray head.

[0013] Compared with the related technology, a sintering plant dust removal sulfurization gas source pipe with convenient connection proposed by the present utility model has the following beneficial effects:

[0014] In the present utility model, for the sintering plant dust removal sulfurization gas source pipe with convenient connection, through the provided dust removal mechanism, the filter screen of the dust removal mechanism is screwed and installed at the end of the elbow through the ring frame connected to its outer side. At the same time, the elbow can be screwed to the smoke inlet pipe through the first connecting flange, which facilitates the disassembly and installation of the elbow. By disassembling the connection between the elbow and the smoke inlet pipe, the dust removal mechanism inside the elbow can be overhauled and maintained. At the same time, the filter screen can also be disassembled from the inner side of the ring groove for cleaning or replacement, which is convenient for the later maintenance of the device. At the same time, a pressure equalizing annular pipe is also provided behind the filter screen. The air jet ports installed on the pressure equalizing annular pipe are aligned with the filter screen. After daily use, high-pressure air flow is introduced through the high-pressure air inlet pipe, and finally the high-pressure air flow is sprayed onto the filter screen through the air jet ports to knock down the dust and blockages on the filter screen, so that the filter screen maintains good use functions, further improving the practicability of the present utility model.

Detailed implementation mode

[0021] The present utility model will be further described below in conjunction with the accompanying drawings and the implementation mode.

[0022] Refer to Figures 1-5 , please refer to Figures 1-5 , wherein, Figure 1 is a three-dimensional structural schematic diagram of a dust removal and sulfurization gas source pipe for a sintering plant with convenient connection proposed by the present utility model Figure 1 ; Figure 2 is a three-dimensional structural schematic diagram of a dust removal and sulfurization gas source pipe for a sintering plant with convenient connection proposed by the present utility model Figure 2 ; Figure 3 is a split three-dimensional structural schematic diagram of a dust removal and sulfurization gas source pipe for a sintering plant with convenient connection proposed by the present utility model; Figure 4 is a partial three-dimensional structural schematic diagram of a dust removal and sulfurization gas source pipe for a sintering plant with convenient connection proposed by the present utility model Figure 1 ; Figure 5 is a partial three-dimensional structural schematic diagram of a dust removal and sulfurization gas source pipe for a sintering plant with convenient connection proposed by the present utility model Figure 2 . A dust removal and sulfurization gas source pipe for a sintering plant with convenient connection includes: an elbow pipe 1 and a vertical pipe 2. A dust removal mechanism 4 is installed inside the elbow pipe 1, and a desulfurization mechanism 5 is installed inside the vertical pipe 2.

[0023] In this mode, the dust removal mechanism 4 includes a ring frame 41 and a pressure equalizing ring pipe 43. A filter screen 42 is fixedly installed inside the ring frame 41. The pressure equalizing ring pipe 43 is fixedly installed on the inner wall of the elbow pipe 1. A number of jet orifices 44 are evenly distributed and installed on the pressure equalizing ring pipe 43. A high-pressure inlet pipe 45 is connected and installed on the pressure equalizing ring pipe 43. The high-pressure inlet pipe 45 extends through to the outside of the elbow pipe 1. A first connecting flange 11 is fixedly installed at the left end of the elbow pipe 1. An annular groove 13 is opened at the left end of the elbow pipe 1. The ring frame 41 is screwed and installed inside the annular groove 13.

[0024] Through the above settings, the pressure equalizing ring pipe 43 in the dust removal mechanism 4 provides a gas supply channel for the jet orifice 44. After introducing high-pressure air flow from the high-pressure air inlet pipe 45, the high-pressure air flow can enter the jet orifice 44 through the pressure equalizing ring pipe 43 and then be sprayed onto the filter screen 42. Then, after the daily use, the dust particles and blockages attached to the filter screen 42 are washed off the filter screen 42, enabling the filter screen 42 to maintain a good filtering function during daily use. Additionally, by using the filter screen 42 to filter the particulate matter in the flue gas, it prevents the particulate matter from clogging the spray heads 55 on the subsequent desulfurization mechanism 5, enabling the desulfurization mechanism 5 to maintain a good spraying effect.

[0025] In this method, the elbow pipe 1 includes a bent section, a horizontal section, and a vertical section. A second connecting flange 12 is fixedly installed at the upper end of the vertical section.

[0026] Through the above settings, the bent section, horizontal section, and vertical section are arranged such that the reactants after desulfurization on the vertical pipe 2 do not flow onto the bent section and all flow into the drain pipe 3 below the horizontal section, thus not affecting the dust removal mechanism 4.

[0027] In this method, a third connecting flange 21 is fixedly installed at the lower end of the vertical pipe 2, and the third connecting flange 21 is screwed to the second connecting flange 12.

[0028] Through the above settings, the vertical pipe 2 is screwed to the second connecting flange 12 on the elbow pipe 1 using the third connecting flange 21, facilitating later disassembly and maintenance work.

[0029] In this method, the desulfurization mechanism 5 includes a number of ring pipes 51. A limestone solution feed pipe 52 and a cleaning water inlet pipe 53 are connected and installed on both sides of the ring pipe 51. A connecting main pipe 54 is connected between the number of ring pipes 51. Spray heads 55 are evenly installed on the ring pipe 51 and the connecting main pipe 54, and the spray heads 55 are atomizing spray heads.

[0030] Through the above settings, after passing through the limestone solution from the limestone solution feed pipe 52, the limestone solution enters the ring pipe 51 and the connecting main pipe 54, and finally is sprayed downward in an atomized form by the spray heads 55 to touch the limestone solution. Then, the limestone solution chemically reacts with and neutralizes the sulfur oxides in the flue gas to achieve the desulfurization effect. The solution formed during the desulfurization process flows through the vertical pipe 2 into the elbow pipe 1 and finally into the drain pipe 3.

[0031] In this method, a drain pipe 3 is connected and installed at the lower end of the horizontal section, and a solenoid valve gate 31 is installed on the drain pipe 3.

[0032] Through the above settings, the solenoid valve gate 31 in the drain pipe 3 can control the opening and closing of the drain pipe 3. During the desulfurization work, the solenoid valve gate 31 remains closed to prevent flue gas leakage.

[0033] In this method, the air jet orifice 44 faces the filter screen 42.

[0034] Through the above arrangement, the air jet orifice 44 facing the filter screen 42 enables the high-pressure air flow ejected from the air jet orifice 44 to directly wash off the dust on the filter screen 42.

[0035] The working principle of a sintering plant dust removal sulfurization gas source pipe with convenient connection provided by the present utility model is as follows:

[0036] During use, the flue gas generated by the sintering plant passes through from the left side of the elbow 1. The flue gas passes through the filter screen 42 in the elbow 1. Then, the dust particles in the flue gas are blocked outside the filter screen 42 under the filtering action of the filter screen 42. The flue gas passing through the filter screen 42 then enters the vertical pipe 2 from the elbow 1. After passing through the limestone solution from the limestone solution feed pipe 52, it enters the annular pipe 51 and the connecting main pipe 54, and finally is sprayed downward by the spray head 55 to touch the limestone solution. Then, the limestone solution chemically reacts and neutralizes the sulfur oxides in the flue gas to achieve the desulfurization effect. The solution formed during the desulfurization process flows from the vertical pipe 2 to the elbow 1 and finally enters the discharge pipe 3. When the flue gas treatment work is completed, the solenoid valve gate 31 on the discharge pipe 3 can be opened to discharge the waste. Subsequently, cleaning water is introduced from the cleaning water inlet pipe 53, and the spray head 55 is used for spraying to clean the pipe walls of the vertical pipe 2 and the elbow 1 to prevent the pipe walls from being adhered by sundries during the desulfurization process. At the same time, after introducing high-pressure air flow from the high-pressure air inlet pipe 45, the high-pressure air flow can enter the air jet orifice 44 through the pressure equalizing annular pipe 43 and then be sprayed onto the filter screen 42. Then, after the daily use is completed, the dust particles and blockages attached to the filter screen 42 are washed off the filter screen 42, enabling the filter screen 42 to maintain a good filtering function during daily use.

[0037] The above are only the embodiments of the present utility model, and do not limit the patent scope of the present utility model accordingly. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present utility model, or directly or indirectly applied to other related technical fields, shall be similarly included within the patent protection scope of the present utility model.
