Description

Technical Field

[0001] The utility model relates to the production and processing of carbon-based purification materials, in particular to a modification system of carbon-based purification materials, and belongs to the technical field of carbon-based purification material production and processing equipment. Background Art

[0002] With the increasing requirements of environmental protection in my country, more and more types of air pollutants are being controlled, and emission standards are becoming more stringent, and the demand for multi-pollutant treatment of industrial flue gas is becoming more urgent. The activated carbon flue gas purification technology with carbon-based materials as the core has been rapidly applied and promoted due to its advantages of high pollutant removal efficiency, no secondary pollution, simple operation, low operating cost, and resource-based by-products. With the rapid promotion of activated carbon flue gas purification technology, the market demand for flue gas purification carbon-based material products has grown rapidly, and the requirements for performance indicators have also been continuously improved. At present, the quality of flue gas purification carbon-based material products still has the problems of low desulfurization and denitrification performance and poor stability, which makes it difficult to adapt to higher flue gas purification requirements, and also directly leads to high operating costs of activated carbon flue gas purification technology; in addition, the technology of flue gas purification carbon-based material preparation industry is relatively backward, the level of automation of production equipment is low, large-scale equipment is rarely put into operation, and there is a lack of unified process equipment standards, which directly leads to low production efficiency and production capacity, and also leads to high production costs. The above problems will affect the quality assurance of carbon-based materials, which will in turn restrict the further development of activated carbon flue gas purification technology. In the prior art, the desulfurization efficiency of carbon-based materials is usually improved by adjusting the raw material formula, but the improvement effect is limited. Because the adjustment of the raw material formula requires a better quality coal, this usually easily leads to increased costs. Studies have shown that it is feasible to modify carbon-based materials to improve their desulfurization efficiency, but the existing activated carbon modification method generally uses a liquid oxidant for oxidation modification. For example, CN113117642B discloses the use of at least one of a nitric acid solution and a hydrogen peroxide solution to impregnate the activated carbon, which requires a large amount of modifiers and has a high investment cost. There are few records of the use of oxidizing gases (such as air) to modify activated carbon in the prior art, and there is also a lack of gas-based modification equipment with low investment costs and stable modification effects.

[0023] Preferably, the feed port and the discharge port are independently provided with air lock rotary valves. An inspection door is also provided on the tower body corresponding to the modified middle chamber.

[0024] In the utility model, the inner cavity of the tower body is divided from top to bottom into an upper feeding chamber, a modified middle chamber and a discharging lower chamber by an upper feeder and a lower feeder, wherein a feed port is provided on the upper feeding chamber for receiving carbon-based materials added from the feed port, and the carbon-based materials are buffered in the upper feeding chamber, and then can be uniformly dropped into the modified middle chamber through the upper feeder, that is, the upper feeding chamber is provided to buffer the carbon-based materials and fully disperse them before passing through the upper feeder, thereby ensuring the consistency of the carbon-based materials from various regions through the upper feeder to ensure the uniformity and stability of the drop. The carbon-based materials in the modified middle chamber flow uniformly from top to bottom, and the oxygen-containing modified gas (such as air) flows from bottom to top, and the carbon-based materials are oxidatively modified in a high temperature environment (such as 400~700℃, which can be achieved by additional heating or the modified gas itself has a high temperature) to increase the specific oxygen-containing functional groups on the surface of the carbon-based materials, thereby improving their adsorption and purification performance. Furthermore, uniform material flow and airflow in the modified chamber are important links in the modification effect. Uniform logistics and airflow are conducive to uniform modification, and can also prevent the oxidation transition caused by uneven modification and the subsequent spontaneous combustion caused by excessive temperature. Therefore, a lower feeder is provided to control the discharge speed of the descending carbon-based material in the modified chamber to achieve uniform discharge. That is to say, uniform feeding is achieved through the upper feeder, and uniform discharging is achieved through the lower feeder, thereby effectively ensuring the uniformity of the material flow rate during the oxidation modification process, which is beneficial to ensuring and promoting the stability and uniformity of the modification effect.

[0025] In the present invention, in order to meet the uniformity of the material in and out of the chamber during the modification, in the preferred embodiment of the present invention, the upper and lower feeders are basically the same in structure, and both include a sealing plate and a feed pipe (i.e., an upper sealing plate, a lower sealing plate, an upper feed pipe, and a lower feed pipe). Taking the above feeder as an example, in the upper sealing plate, an upper feed pipe is provided at the center thereof, which is called the central upper feed pipe. On the outer side of the central upper feed pipe, a plurality of upper feed pipes are arranged in a regular hexagonal arrangement manner (i.e., the centers of all upper feed pipes in the same layer are connected in sequence to form a hexagon, the closer to the outside, the larger the regular hexagon, and the spacing between any two adjacent layers of regular hexagons is the same) until it is spread over the entire upper sealing plate, that is, the radial spacing between any two adjacent upper feed pipes is the same. That is, through the design of the upper and lower feeders with special structural designs, the uniform downward movement of carbon-based materials in the oxidation modification area is achieved, which is conducive to promoting the uniformity of the modification effect.

[0026] In the utility model, in order to make the modified gas evenly distributed, gas inlets and outlets are respectively arranged on the outer side of the tower body at the lower end of the lower and upper bulkers. The gas inlets and outlets are designed to be symmetrically arranged on at least two opposite side walls of the tower body, and can also be evenly distributed around the outer wall of the entire tower body. The main airflow pipeline (including the air intake main pipe and the exhaust main pipe) is connected to the inlet and outlet through multiple airflow branches (including the air intake branch pipe and the exhaust branch pipe), and is provided with a high-temperature gasket and fixed to the tower body by bolts. In order to prevent the beneficial large particles from flowing out of the pipeline, a grid with a certain slope is set at the gas inlet and outlet. In addition, the feed pipes (including the upper feed pipe and the lower feed pipe) extend downward from the sealing plate to a certain length. After the material flows out of the feed pipe, an empty area will be formed between the feed pipe outlet and the sealing plate, which is conducive to the formation of an air chamber. The modified gas enters the oxidation zone from the air chamber at the lower end of the lower sealing plate through the lower feed pipe and penetrates the material layer, and then converges in the air chamber at the lower end of the upper sealing plate, and then flows out through the gas outlet. This is conducive to the gas flowing into the lower feed pipes of all the lower feeders, and then evenly distributed in the oxidation zone, so as to improve the uniformity of contact between the modified gas and the carbon-based material.

[0027] In the utility model, the lower discharge chamber is a top-down tapered design, and a material hopper is arranged in the lower discharge chamber. A plurality of material hoppers are evenly distributed in the lower discharge chamber and are connected to each other to form a horizontal lattice structure. In the lower discharge chamber, multi-layer lattice structure material hoppers are arranged from top to bottom, and the number of material hoppers in the upper lattice structure is 1.5 to 3.5 times the number of material hoppers in the lower lattice structure (preferably 2 times, and the number of material hoppers in the lowest layer is 1, that is, all material hoppers form an inverted pyramid distribution as a whole). The design of multi-layer lattice structure material hoppers further improves the uniformity of carbon-based material discharge, which is conducive to ensuring the uniformity of carbon-based materials flowing downward in the entire tower body inner cavity.

[0028] In the utility model, multiple temperature sensor interfaces are provided on the tower body, and temperature sensors of different lengths can be installed to track the temperature changes in different areas of the oxidation zone. If there is a sharp increase in local temperature, corresponding measures can be taken to solve it. In addition, a water cooling jacket is provided outside the constriction section of the lower chamber of the discharge, and the material is quickly cooled by circulating cooling water.

[0029] Compared with the prior art, the beneficial technical effects of the utility model are as follows:

[0030] 1: The modification system of the carbon-based purification material of the utility model can realize uniform and temperature oxidation modification of the carbon-based material by using low-cost oxidants such as air, by cleverly arranging an upper material loader, a lower material loader, a modified gas intake mechanism and a modified gas exhaust mechanism in the inner cavity of the tower body, and the equipment and production investment costs are low.

[0031] 2: The modification system of the carbon-based purification material of the utility model also has the characteristics of simple structure, easy operation, low equipment investment cost, simple maintenance, good oxidation modification effect, stable modification effect, and strong practicality.
