Description

Technical Field

[0001] The utility model relates to the technical field of desulfurization, in particular to a feeding device and a desulfurization system. Background Art

[0002] At present, when thermal power plants burn high-sulfur coal, if the sulfur content of the coal is high and the output of the desulfurization system cannot meet the sulfur dioxide emission needs, it is necessary to add desulfurization enhancers to improve the desulfurization efficiency. The bagged enhancers are added to the drainage pit of the absorption tower and transported to the absorption tower through the drainage pit pump. Each time the operator adds the enhancer, 15 to 25 bags are needed. Each bag needs to be disassembled and the enhancer is added to the drainage pit of the absorption tower. The workload of adding is large and the efficiency is low. Sometimes, due to the long time of adding the enhancer, the desulfurization efficiency cannot be improved in time, resulting in the load limit of the unit and the excessive sulfur dioxide, which leads to the failure to meet the emission standards and reduce the company's profits.

[0003] Therefore, there is an urgent need for a delivery device and a desulfurization system to reduce the delivery difficulty and improve the delivery efficiency. Utility Model Content

[0038] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only the parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0039] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0040] In the present utility model, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0041] In the description of this embodiment, the terms "upper", "lower", "right", etc., are based on the directions or positions shown in the drawings, and are only for the convenience of description and simplified operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation of the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0042] This embodiment provides a desulfurization system, such as Figure 1 As shown, the desulfurization system includes a reaction vessel 50, a pumping member 60, an absorption tower and a feeding device, the feeding device is connected to the reaction vessel 50, the pumping member 60 is arranged downstream of the reaction vessel 50, and the pumping member 60 is connected to the reaction vessel 50 and the absorption tower through a pipeline 70, so that the pumping member 60 can pump the reaction solution to the absorption tower (the flow direction of the reaction solution is as shown in FIG. Figure 1 In the direction of the middle arrow, the absorption tower is not shown in the figure). In addition, a pressure detection member 80 is also provided between the pumping member 60 and the absorption tower, and the pressure detection member 80 can detect the pressure of the reaction solution after the pumping member 60 is discharged, so as to judge whether the pumping member 60 is operating normally. However, there is a problem that the feeding device in the prior art requires the operator to feed the materials one by one, which is difficult to feed, the feeding efficiency is extremely low, and the desulfurization effect is not good.

[0043] To solve the above problems, this embodiment also provides a feeding device for feeding materials into the reaction container 50, such as Figure 2 As shown, the delivery device includes a box body 10, a first baffle 20 and a second baffle 30, wherein a delivery port 11 is opened at the top of the box body 10 for delivering materials, and an injection port is arranged at the bottom end of the box body 10, and the injection port is connected with the reaction container 50 so that the material can flow into the reaction container 50; the first baffle 20 is arranged at the injection port, and the first baffle 20 can block or open the injection port; the second baffle 30 is arranged at the bottom end of the first baffle 20, and the second baffle 30 can seal the injection port so that water vapor in the reaction container 50 cannot enter the box body 10 from the injection port.

[0044] It should be noted here that in this embodiment, the material is a desulfurization synergist, so as to improve the desulfurization efficiency. The desulfurization synergist is generally packed in bags, each bag is 25 kg, and each desulfurization needs to be put in 15-25 bags at a time. Therefore, in this device, by setting the first baffle 20, 15-25 bags of desulfurization synergist can be put into the box 10 in advance, and due to the sealing effect of the first baffle 20, the desulfurization synergist can be stored in the box 10. When it is needed to be put in, only the first baffle 20 needs to be opened, and the desulfurization synergist in the box 10 can quickly enter the reaction container 50; in addition, since there is a reaction solution in the reaction container 50, in order to prevent the water vapor of the reaction solution from volatilizing into the box 10, thereby causing the desulfurization synergist to become damp and ineffective, a second baffle 30 is also provided in this embodiment. The second baffle 30 can block the water vapor volatilized in the reaction container 50 from entering the box 10 through the gap between the first baffle 20 and the injection port, thereby ensuring that the desulfurization synergist can smoothly participate in the reaction after being put into the reaction container 50, thereby ensuring the desulfurization effect.

[0045] like Figure 3 As shown, in this example, an inflatable seal 90 is provided on the outer periphery of the second baffle 30, and the inflatable seal 90 is configured to seal the connection between the second baffle 30 and the reaction container 50 when the first baffle 20 blocks the injection port. That is, when the injection port needs to be blocked, the second baffle 30 is located between the connection port of the first baffle 20 and the reaction container 50, and inflates the inflatable seal 90 to expand it (such as Figure 3 The gap between the second baffle 30 and the connection port of the reaction container 50 is filled to ensure its sealing, thereby effectively preventing water vapor from volatilizing from the reaction container 50, so that the desulfurization synergist will not become ineffective due to moisture.

[0046] In addition, the first baffle 20 and the second baffle 30 are connected by a connecting member so that the first baffle 20 and the second baffle 30 can move simultaneously. When the first baffle 20 moves, the second baffle 30 can move with the first baffle 20 under the action of the connecting member, thereby ensuring that the first baffle 20 and the second baffle 30 move simultaneously, so that when the first baffle 20 blocks the injection port, the second baffle 30 can cover the connection port of the reaction container 50, and the inflatable seal 90 can fill the gap between the connection port of the second baffle 30 and the reaction container 50, thereby ensuring the sealing performance; in addition, the simultaneous movement of the first baffle 20 and the second baffle 30 can also ensure that the material can smoothly enter the reaction container 50, ensuring good usability.

[0047] It should be noted here that, in this example, the first baffle 20 is a pneumatic plug-in isolation door. This structure has a good isolation effect, a small size, and is not restricted in the installation position. It can be applied to horizontal, vertical or inclined pipelines.

[0048] like Figure 1 As shown, the box 10 includes a main body 12 and a cone 13 connected in sequence along its axial direction, a delivery port 11 is arranged at the top of the main body 12, and the diameter of the cone 13 gradually decreases in a direction away from the main body 12 to form an injection port. The delivery port 11 is arranged at the top of the main body 12, which can prevent the material from overflowing from the delivery port 11 when there is a lot of material in the box 10, thereby avoiding material waste; in addition, the diameter of the cone 13 gradually decreases in a direction away from the main body 12, which can ensure that the material can flow out from the injection port at a faster speed, so that the material can smoothly fall into the reaction container 50, thereby ensuring smooth desulfurization.

[0049] Considering that there may be residual material at the connection between the side wall of the cone portion 13 and the injection port, the material cannot be completely introduced into the reaction container 50. Figure 2 As shown, an arc-shaped protrusion 40 is provided at the connection between the side wall of the cone portion 13 and the injection port, and an arc-shaped protrusion 40 is provided at the connection along the circumference of the injection port. This structure can ensure that the material will not remain at the connection between the injection port and the side wall of the cone portion 13. The material can slide smoothly from the arc-shaped protrusion 40 to the injection port and then fall into the reaction vessel 50, ensuring that all the material can enter the reaction vessel 50.

[0050] like Figure 1 As shown, the diameter of the main body 12 remains unchanged along its axial direction. In this structure, since the main body 12 is cylindrical as a whole, it is ensured that there is no part protruding outward to scratch the staff; in addition, the overall diameter remains unchanged, which can ensure that the material can be only affected by gravity in the main body 12 and can fall smoothly into the cone 13, thereby ensuring that the material can be smoothly put into the cone. Figure 1 and Figure 2 As shown, the diameter of the delivery port 11 is smaller than the diameter of the main body 12. The smaller diameter of the delivery port 11 can prevent other impurities except the material from entering the box 10 from the delivery port 11, thereby causing the desulfurization synergist to fail.

[0051] The following is a description of the use process of the delivery device and the desulfurization system in this example with reference to the accompanying drawings:

[0052] First, the first baffle 20 and the second baffle 30 are used to block and seal the injection port, and 15-25 bags of desulfurization synergist are added into the box body 10 at one time through the injection port 11;

[0053] Secondly, when the desulfurization synergist needs to be added, the first baffle 20 and the second baffle 30 are opened, so that the desulfurization synergist can all fall into the reaction container 50;

[0054] Finally, the pumping member 60 is started to pump the reaction solution into the absorption tower.

[0055] In summary, the delivery device provided in this example can not only avoid the inconvenience of delivering materials bag by bag and the problem of ineffective desulfurization, but also improve the overall work efficiency.

[0056] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the claims of the present invention.
