[0002] To address the issues of solid waste disposal and effective utilization of carbide slag, and to maximize economic benefits, the desulfurization agent in the generator set desulfurization system is made by mixing carbide slag with limestone, thereby reducing production costs.

[0003] Currently, the calcium carbide slag pulping system mainly includes a calcium carbide slag storage device, a calcium carbide slag feeding device, a calcium carbide slag conveying device, and a calcium carbide slag slurry device. The calcium carbide slag storage device is a calcium carbide slag stockpile. Industrial exhaust fans are appropriately installed within the stockpile to ensure smooth air circulation and prevent residual acetylene gas buildup. The calcium carbide slag feeding device uses a transfer loader to feed material into the upper feeding hopper. The feeding hopper is equipped with a hopper wall vibrator and the hopper is smoothed to ensure material transport. The calcium carbide slag conveying device mainly consists of a conveyor belt. The conveyor belt is located below the feeding hopper to transport the material out. The calcium carbide slag slurry device has multiple calcium carbide slag slurry tanks, each corresponding to a calcium carbide slag transfer conveyor belt, unloading the calcium carbide slag transferred by the conveyor belt into the slurry tank.

[0004] During the use of the aforementioned carbide slag pulping system, the belt conveyor frequently experienced blockages, spillage, belt misalignment, and slippage, which severely restricted the carbide slag pulping process and resulted in the carbide slag usage failing to meet system requirements. Utility Model Content

[0005] To address some or all of the aforementioned technical problems in the prior art, a desulfurizing agent carbide slag feeding device and a carbide slag slurry preparation device comprising the device are provided. This desulfurizing agent carbide slag feeding device avoids the use of belt conveyors to transport carbide slag, thus achieving reliable transportation of the desulfurizing agent carbide slag.

Attached Figure Description

[0024] The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings, in which:

[0025] Figure 1The schematic diagram illustrates the desulfurizing agent carbide slag feeding device and process water source of this utility model embodiment;

[0026] Figure 2 The illustration schematically shows the second flushing component of the desulfurizing agent carbide slag feeding device according to an embodiment of the present invention.

[0027] In the accompanying drawings, the same parts use the same reference numerals. The drawings are not drawn to scale. Detailed Implementation

[0028] To make the technical solution and advantages of this utility model clearer, the exemplary embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not an exhaustive list of all embodiments. Furthermore, without conflict, the embodiments and features in the embodiments of this utility model can be combined with each other.

[0029] Figure 1 The schematic diagram illustrates the overall structure of the desulfurizing agent carbide slag feeding device according to an embodiment of this utility model. For example... Figure 1 As shown, the desulfurizing agent calcium carbide slag feeding device of this utility model embodiment includes a slurry tank 1, a feeding hopper 2, a guide channel 3, and a first flushing component 4. The slurry tank 1 is mainly used to receive and store the desulfurizing agent calcium carbide slag material for a limited time, serving as a transfer station for the desulfurizing agent calcium carbide slag and part of the process water. The feeding hopper 2 is located at the first end of the slurry tank 1, and its outlet is connected to the inner cavity of the slurry tank 1. Feeding is performed into the slurry tank 1 through the feeding hopper 2. The guide channel 3 is connected at the second end of the slurry tank 1. This guide channel 3 is used to transport the desulfurizing agent calcium carbide slag in the slurry tank 1 to the slurry pool. The first flushing component 4 is located on the feeding hopper 2. The first flushing component 4 is used to selectively connect to the process water source 8 to flush the desulfurizing agent calcium carbide slag in the feeding hopper 2 into the slurry tank 1.

[0030] As can be seen, in this application, the desulfurizing agent calcium carbide slag is fed into the feeding hopper 2 and, under its own gravity and the action of the flushing process water, is transported to the slurry tank 1. In the slurry tank 1, the process water and the desulfurizing agent calcium carbide slag are further mixed. The desulfurizing agent calcium carbide slag, after being mixed with the process water, flows into the guide channel 3 and is then transported to the downstream slurry pool. Therefore, in this application, the desulfurizing agent calcium carbide slag is transported to the slurry pool via the slurry tank 1 and the guide channel 3, avoiding the use of a belt conveyor. During transport, the desulfurizing agent calcium carbide slag can be well contained within the slurry tank 1 and the guide channel 3, preventing spillage and improving civilized production. Furthermore, the first flushing component 4 can flush the desulfurizing agent calcium carbide slag, ensuring smooth transport and allowing the desulfurizing agent calcium carbide slag to mix with the process water in advance, improving the slurry production efficiency of the entire calcium carbide slag slurry system.

[0031] In one embodiment, a rod valve 5 is provided at the outlet of the feeding hopper 2. By setting the rod valve 5, the flow area of ​​the rod valve can be controlled by adjusting the gap between the rods, thereby regulating the flow rate of the material and achieving precise adjustment of the ratio of process water to desulfurizing agent carbide slag.

[0032] The inner bottom wall of the slurry tank 1 is inclined, with the first end higher than the second end. Preferably, the inclination angle of the inner bottom wall of the slurry tank 1 is 15 to 20 degrees, for example, 18 degrees. This inclination angle is adjusted to regulate the material conveying efficiency. The specific value ensures both sufficient mixing of process water and desulfurizing agent calcium carbide slag, and efficient conveying of both. In this application, after the desulfurizing agent calcium carbide slag feeding device is installed, the inclination angle of the inner bottom wall of the slurry tank 1 refers to the angle formed between the extended surface of the inner bottom wall of the slurry tank 1 and the installation plane, such as the earth.

[0033] A second flushing element 6 is installed on the first end wall of the slurry tank 1. The second flushing element 6 is used to connect to the external process water source 8. By installing the second flushing element 6, the material can be moved downstream, preventing material accumulation and ensuring the normal operation of the desulfurizing agent / carbide slag feeding device. Figure 2 As shown, for example, the second flushing component 6 includes a flushing pipe 61. The flushing pipe 61 is connected to a process water source 8 and serves to transport process water. Along the length of the flushing pipe 61, a plurality of nozzles 62, for example, four or more, are provided and communicate with the flushing pipe 61. After installation, in Figure 1 In the orientation shown, the length of the flushing pipe 61 extends in the inward and outward direction, that is, the length of the flushing pipe 61 is perpendicular to the direction from the first end to the second end. The nozzle 62 faces the direction of the second end. Thus, in the inner cavity of the slurry tank 1, the flushing pipe 61 is located at the first end and sprays process water towards the second end to effectively promote the movement of the desulfurizing agent carbide slag downstream.

[0034] To facilitate the smooth downstream flow of the desulfurizing agent calcium carbide slag and process water mixture, the inner bottom wall of the guide channel 3 is also constructed as an incline, with the first end higher than the second end. Preferably, the incline angle of the inner bottom wall of the guide channel 3 is 25 to 35 degrees, for example, 30 degrees. The incline angle of the inner bottom wall of the guide channel 3 refers to the angle formed between the extended surface of the inner bottom wall of the guide channel 3 and the mounting plane, such as the ground. This incline angle can effectively ensure the rapid flow of the desulfurizing agent calcium carbide slag and process water, thereby improving the slurrying efficiency. A third flushing element 7 is provided in the guide channel 3. The third flushing element 7 is used to connect to the external process water source 8. The main purpose of the third flushing element 7 is to avoid material accumulation and ensure smooth material transport. The specific structure of the third flushing element 7 can be the same as or similar to that of the second flushing element 6. The flushing pipe of the third flushing element 7 is located at the first end of the guide channel 3, and the nozzle sprays towards the second end to promote the uniform flow of the desulfurizing agent calcium carbide slag and process water.

[0035] According to this application, the height from the bottom wall of the first end of the guide channel 3 to the bottom wall of the second end of the slurry tank 1 is one-sixth to one-half the height of the side wall of the second end of the slurry tank 1, for example, one-third. That is, the guide channel 3 connects to one-third of the height of the slurry tank 1. At the same time, a drain outlet 11 selectively communicates with the outside is provided on the bottom wall of the second end of the slurry tank 1. For example, a cover 12 threadedly connected to the slurry tank 1 is provided at the drain outlet 11 to allow selective communication between the slurry tank 1 and the outside. The above arrangement ensures that the mixture of desulfurizing agent calcium carbide slag and process water in the slurry tank 1 does not flow smoothly and unimpeded directly into the guide channel 3. The side wall of the second end of the slurry tank 1 has a certain blocking effect on the mixture of desulfurizing agent calcium carbide slag and process water. This method can ensure that the heavy metals in the mixture of desulfurizing agent calcium carbide slag and process water can be effectively deposited in the slurry tank 1, reducing the flow of heavy metals downstream into the guide channel 3. After the desulfurizing agent carbide slag feeding device has been in operation for a long time, the heavy metals and other deposits settled in the slurry tank 1 can be cleaned out by opening the drain outlet 11.

[0036] This application also relates to a calcium carbide slag pulping device. This calcium carbide slag pulping device includes the aforementioned desulfurizing agent calcium carbide slag feeding device, a process water source 8, and a pulping tank (not shown in the figure). The process water source 8 is mainly used to supply process water. The process water is the same material added to the pulping tank in the prior art, for example, it can be gypsum filtrate water or desulfurization process water. The process water source 8 is connected to the first flushing component 4, the second flushing component 6, and the third flushing component 7 via pipelines 9. Regulating valves 10 are installed at appropriate locations on the main line and each branch line of pipeline 9 to control the switching on / off of the process water and the flow rate. The pulping tank is connected to the second end of the guide channel 3 to receive the desulfurizing agent calcium carbide slag and process water mixture from the guide channel 3.

[0037] The following is based on Figure 1 and 2 Describe the working process of the desulfurizing agent calcium carbide slag feeding device.

[0038] First, check if the rod valve 5 is functioning properly and adjust it to the working state. Then, open the second flushing component 6 and the third flushing component 7 to release flushing water into the slurry tank 1 and the guide channel 3 to clean them and prevent material buildup. Next, open the first flushing component 4 to spray process water into the upper hopper 2. Then, feed material into the upper hopper 2. Under the action of the process water at the first flushing component 4, the desulfurizing agent calcium carbide slag enters the slurry tank 1 through the rod valve 5. The mixture of desulfurizing agent calcium carbide slag and process water in the slurry tank 1 then enters the guide channel 3 and is finally transported to the slurry pool. During this desulfurizing agent calcium carbide slag transportation process, the process water serves not only as slurry water but also as flushing water. During the material transportation process, the slurry density can also be tested to reasonably adjust and control the amount of process water and the amount of desulfurizing agent calcium carbide slag fed.

[0039] After feeding is completed, feeding into hopper 2 must be stopped first. Once the desulfurizing agent / carbide slag in hopper 2 has entered the slurry tank 1, the first flushing component 4 should be closed. After the mixture of desulfurizing agent / carbide slag and process water has basically all flowed into the slurry tank, the second flushing component 6 and the third flushing component 7 should be closed. Finally, the drain outlet 11 should be opened to clean the slurry tank 1.

[0040] In this application, process water is used as both rinsing water and pulping water. It needs to be combined with rod valves to form a reasonable slurry ratio adjustment. Operators need to make timely adjustments and subsequent optimizations to ensure that the pulping density is within a reasonable range and to select and control the rinsing quantity.
