Description

Technical Field

[0001] This invention belongs to the field of sulfur-loaded activated carbon technology, and particularly relates to nitrogen doping devices. Background Technology

[0002] Sulfur-loaded activated carbon is a material that uses activated carbon as a carrier and loads sulfur or other active components to enhance its adsorption capacity for specific substances (such as mercury and sulfides). It is commonly used in environmental and industrial treatment fields such as desulfurization and mercury removal. During the preparation process, sulfur can be loaded onto the surface of activated carbon through physical adsorption or chemical bonding. The presence of sulfur can significantly improve the adsorption performance of activated carbon for pollutants such as mercury because it can chemically react with mercury to form stable compounds, such as mercuric sulfide (HgS), thus effectively preventing secondary escape of mercury. Furthermore, factors such as the sulfur content, specific surface area, pore structure, and the form in which sulfur exists all affect the adsorption efficiency of sulfur-loaded activated carbon.

[0003] Existing sulfur-loaded activated carbon devices have some problems in practical applications. For example, the sulfur immobilization effect is not ideal, which makes sulfur easy to be lost during use and reduces the adsorption efficiency. The structural design of the device may not be optimized, resulting in insufficient contact between the activated carbon and the gas or liquid to be treated, which affects the adsorption performance. Utility Model Content

[0004] This invention provides a nitrogen-doping device, which aims to solve the problems of easy sulfur loss and unreasonable structure in existing sulfur-loaded activated carbon devices, which affect adsorption efficiency and performance.

[0005] This invention is implemented as follows: a nitrogen doping device includes: a heater; a multi-layer filter assembly mounted on the heater, the multi-layer filter assembly being used for filtration; a pH pre-adjustment assembly mounted on top of the multi-layer filter assembly, the pH pre-adjustment assembly being used for pre-treating the raw solution; a gas collection assembly mounted on top of the multi-layer filter assembly, the gas collection assembly being used for collecting reaction gases; a filter assembly cleaning assembly mounted on top of the multi-layer filter assembly, the filter assembly cleaning assembly being used for cleaning the multi-layer filter assembly; and a waste liquid recycling assembly mounted at the bottom of the multi-layer filter assembly, the waste liquid recycling assembly being used for recycling waste liquid.

[0006] Preferably, the multi-layer filter assembly includes: a filter barrel fixedly installed inside the heater, a flow divider fixedly installed on the filter barrel, a flow divider channel opened on the flow divider, a filter plate fixedly installed inside the filter barrel, and a filter groove opened on the inner side of the filter plate.

[0007] Preferably, the diverter, diverter channel, filter plate, and filter groove are provided in three sets, and the three sets of diverter, diverter channel, filter plate, and filter groove are equidistantly arranged inside the filter barrel.

[0008] Preferably, the pH pre-adjustment assembly includes: a control valve pipe fixedly installed on the top of the filter tank, a neutralization tank fixedly installed on the top of the control valve pipe, a feed hopper fixedly installed on the top of the neutralization tank, a pH detector fixedly installed on the top of the neutralization tank, and an acid / base injection pipe fixedly installed on the top of the neutralization tank.

[0009] Preferably, the gas collection assembly includes: a control valve pipe two fixedly installed on the top of the filter barrel, a collection bottle fixedly installed on the top of the control valve pipe two, and a control valve fixedly installed on the top of the collection bottle.

[0010] Preferably, the filter assembly cleaning assembly includes: a control valve three fixedly installed on the top of the filter tank, a cleaning agent storage tank fixedly installed on the top of the control valve three, and an injection pipe fixedly installed on the top of the cleaning agent storage tank.

[0011] Preferably, the waste liquid recycling assembly includes: a waste liquid tank fixedly installed at the bottom of the filter tank, a water pump fixedly installed at the top of the waste liquid tank, an outlet pipe fixedly installed at the top of the water pump, and one end of the outlet pipe fixedly installed inside the filter tank.

[0012] Preferably, the waste liquid recycling assembly further includes: an inlet pipe fixedly installed at one end of the water pump, one end of the inlet pipe fixedly installed on one side of the waste liquid tank, and a drain pipe fixedly installed on one side of the waste liquid tank.

[0013] Compared with related technologies, the nitrogen-doped device provided by this utility model has the following advantages: When using this nitrogen doping device, the raw solution is first added to the neutralization tank through the feed hopper. The acid-base injection pipe injects appropriate amounts of acid or alkali substances to adjust the pH of the raw solution based on the pH detector results. The adjusted raw solution flows into the filter tank through control valve one. The flow divider and flow channel ensure even distribution of the raw solution. It is then filtered through the filter plate and filter grooves, effectively intercepting impurities, improving filtration efficiency, and reducing interference from impurities in subsequent reactions. The filtered liquid continues to flow downwards into the heater for heating, providing a suitable temperature for the nitrogen doping reaction. Gases generated during the reaction enter the collection bottle through control valve two of the gas collection assembly, and are ultimately discharged by the control valve or subjected to further treatment, achieving effective collection and management of reaction gases and preventing gas escape that could cause pollution or resource waste. When cleaning the filter assembly is required, cleaning agent from the cleaning agent storage tank is injected into the filter tank through control valve three to clean the filter assembly. The waste liquid after cleaning flows into the waste liquid tank, and the water pump extracts the waste liquid through the inlet pipe and re-injects it into the filter tank through the outlet pipe for recycling. If the waste liquid reaches a certain volume or does not meet the recycling requirements, it is discharged through the drain pipe. This device improves filtration efficiency and precision through the optimized design of multi-layer filtration components, reducing the impact of impurities on the adsorption performance of activated carbon. At the same time, the inclusion of gas collection components and waste liquid recycling components improves resource utilization and reduces the risk of environmental pollution. It also solves, to some extent, the problems of easy sulfur loss and unreasonable structure in existing sulfur-loaded activated carbon devices, thereby effectively improving adsorption efficiency and overall performance.
