Abstract
Description
Technical Field
[0001] This utility model relates to the field of semi-coke wastewater technology, specifically a circulating treatment device for semi-coke wastewater. Background Technology
[0002] Semi-coke is a new type of coal conversion product. Due to its low price and advantages such as high fixed carbon, high resistivity, and high chemical activity, it is widely used in industries such as calcium carbide, ferroalloys, fertilizer gasification, blast furnace injection, and the manufacture of clean coal for civilian use. Semi-coke wastewater is the wastewater generated during the low-temperature dry distillation of coal (about 650℃). It mainly comes from the circulating water of cooling and washing coal gas and the separation water in the chemical production process. Semi-coke is produced by low-temperature dry distillation, which produces a large amount of tar and low-molecular-weight organic matter. Therefore, the wastewater contains a large amount of pollutants that have not been oxidized at high temperatures. Its concentration is about 10 times higher than that of coking wastewater, making it more difficult to treat than coking wastewater.
[0003] Chinese Utility Model Patent Publication No. CN218931880U discloses a semi-coke wastewater treatment device. This device, equipped with a motor, rotating shaft, spiral blades, and support plate, rotates the shaft when the motor is started. The rotating shaft, in turn, drives the spiral blades to stir the semi-coke wastewater and flocculant, thereby treating the wastewater and effectively improving sedimentation and filtration. It boasts high filtration efficiency and a simple structure. However, while this device achieves filtration and sedimentation, it does not facilitate the treatment of the adsorbent, hindering its secondary recycling and leading to resource waste. Therefore, its widespread adoption is impractical. Summary of the Invention
[0004] The technical problem to be solved by this utility model is to provide a circulating treatment device for semi-coke wastewater, which can effectively solve the problems in the prior art.
[0005] The technical solution adopted by this utility model is: a circulating treatment device for semi-coke wastewater, including a treatment tank, a fixed base and a negative pressure extraction component. A booster pump is fixedly installed on the fixed base. A connecting pipe is provided at the output end of the booster pump. A methanol storage tank is fixedly installed on the outer wall of the treatment tank at the end of the connecting pipe away from the booster pump. A connecting pipe is provided at the end of the methanol storage tank away from the booster pump and communicates with the treatment tank. A heating component is provided inside the treatment tank.
[0006] The negative pressure extraction assembly includes a negative pressure tank, one end of which is provided with an extraction pipe, and the end of the extraction pipe away from the negative pressure tank is provided with an extraction pump.
[0007] The heating assembly includes a heating box, and a liquid flow pipe is fixedly installed along the inner edge of the heating box.
[0008] Preferably, a solenoid valve is provided at the outer edge of the connecting pipe, a filter plate is fixedly installed at the inner edge of the processing box, and a sandwich layer is provided at the end of the processing box away from the filter plate.
[0009] Through the above technical solution, after the booster pump is started, the methanol in the methanol storage tank can be pumped into the treatment tank through connecting pipe one and connecting pipe two to wash the adsorbent. The methanol washing adsorbent step can effectively remove the pollutants attached to the surface of the adsorbent, restore its adsorption performance, and facilitate subsequent recycling.
[0010] Preferably, a discharge pipe is provided at the other end of the extraction pump away from the extraction pipe two, and the negative pressure tank, extraction pipe one, extraction pump, extraction pipe two and discharge pipe are interconnected.
[0011] With the above technical solution, when the negative pressure extraction component is working, the extraction pump extracts gas from the processing tank through extraction pipe one, forming a negative pressure environment in the negative pressure tank. This causes easily liquefied products in the processing tank to vaporize and be extracted, and then discharged through extraction pipe two and discharge pipe. The negative pressure environment lowers the boiling point of the products, allowing easily liquefied substances to vaporize and separate at a lower temperature, avoiding the influence of high temperature on the performance of the adsorbent, thereby obtaining a dry adsorbent.
[0012] Preferably, a slot is provided along the inner edge of the heating box, and a cover plate is placed in the heating box through the slot. A locking block is fixedly installed on one end of the cover plate near the heating box, and the slot and the locking block are compatible.
[0013] Through the above technical solution, when the heating component is working, it can heat the medium in the liquid flow pipe, thereby heating the adsorbent in the treatment tank. The heating step can improve the solubility of the solute, accelerate the chemical reaction or adsorption-desorption process, and improve the treatment efficiency of semi-coke wastewater.
[0014] Preferably, a control box is provided at one end of the processing box, and an extraction pipe two is provided at the end of the extraction pump away from the extraction pipe one.
[0015] Through the above technical solution, the control box can centrally control the start and stop of the device. In conjunction with the extraction pipe 2 connecting the extraction pump and the discharge pipe, the gas transmission during the negative pressure extraction process can be achieved.
[0016] Preferably, the liquid flow pipe has an inverted "S" shaped cross-section, and both ends of the liquid flow pipe penetrate the treatment tank and extend to its outer surface.
[0017] Through the above technical solution, the inverted "S"-shaped liquid flow pipe can increase the contact area with the substances in the treatment tank, prolong the residence time of the heating medium, and improve the heating efficiency.
[0018] Preferably, a slag discharge pipe is provided at the end of the treatment box away from the center line, and a water outlet tank and a water inlet pipe are provided at the end of the treatment box near the slag discharge pipe.
[0019] Through the above technical solution, the slag discharge pipe can periodically discharge the impurities settled in the treatment tank, keep the inside of the equipment clean, and avoid the accumulation of impurities affecting the treatment effect. The water inlet pipe is used to inject the semi-coke wastewater to be treated, and the water outlet tank can collect the treated water for subsequent testing and discharge.
[0020] Compared with the prior art, this utility model provides a circulating treatment device for semi-coke wastewater, which has the following beneficial effects:
[0021] 1. The semi-coke wastewater is treated using a circulating equipment. When the negative pressure extraction component is working, the extraction pump draws gas from the treatment tank through extraction pipe one, creating a negative pressure environment in the negative pressure tank. This causes easily liquefied products in the treatment tank to vaporize and be extracted, then discharged through extraction pipe two and discharge pipe. The negative pressure environment lowers the boiling point of the products, allowing easily liquefied substances to vaporize and separate at a lower temperature, avoiding the impact of high temperature on the adsorbent performance, thus obtaining a dry adsorbent. After the pressure pump is started, methanol in the methanol storage tank can be pumped into the treatment tank through connecting pipe one and connecting pipe two to wash the adsorbent. The methanol washing step can effectively remove pollutants attached to the surface of the adsorbent, restore its adsorption performance, and facilitate subsequent recycling.
[0022] 2. The semi-coke wastewater is treated using a circulating equipment. The inverted "S"-shaped liquid flow pipe can increase the contact area with the substances in the treatment tank, prolong the residence time of the heating medium, and improve the heating efficiency. When the heating components are working, they can heat the medium in the liquid flow pipe, thereby heating the adsorbent in the treatment tank. The heating step can improve the solubility of the solute, accelerate the chemical reaction or adsorption-desorption process, and improve the treatment efficiency of the semi-coke wastewater.

[0034] Specifically, a solenoid valve 8 is installed at the outer edge of the connecting pipe 2 7, and a filter plate 10 is fixedly installed at the inner edge of the treatment box 1. A jacket 11 is opened at the end of the treatment box 1 away from the filter plate 10. The advantage is that after the booster pump 4 is started, the methanol in the methanol storage tank 6 can be pumped into the treatment box 1 through the connecting pipe 1 5 and the connecting pipe 2 7 to wash the adsorbent. The methanol washing adsorbent step can effectively remove the pollutants attached to the surface of the adsorbent, restore its adsorption performance, and facilitate subsequent recycling.
[0035] Specifically, the other end of the extraction pump 903, away from the extraction pipe 904, is equipped with a discharge pipe 905. The negative pressure tank 901, extraction pipe 902, extraction pump 903, extraction pipe 904, and discharge pipe 905 are interconnected. The advantage is that when the negative pressure extraction component 9 is working, the extraction pump 903 extracts gas from the processing tank 1 through extraction pipe 902, forming a negative pressure environment in the negative pressure tank 901. This causes easily liquefied products such as water or methanol in the processing tank 1 to vaporize and be extracted, and then discharged through extraction pipe 904 and discharge pipe 905. The negative pressure environment lowers the boiling point of the products, allowing easily liquefied substances to vaporize and separate at a lower temperature, avoiding the influence of high temperature on the performance of the adsorbent, thereby obtaining a dry adsorbent.
[0036] Specifically, a slot 1202 is provided along the inner edge of the heating box 1201. A cover plate 1203 is placed in the heating box 1201 through the slot 1202. A locking block 1204 is fixedly installed at one end of the cover plate 1203 near the heating box 1201. The slot 1202 and the locking block 1204 are compatible.

The advantage is that the control box 2 can centrally control the start and stop of other parts. With the extraction pipe 2 904 connecting the extraction pump 903 and the discharge pipe 905, the transmission of gas during the negative pressure extraction process can be achieved.
[0039] Specifically, the liquid flow pipe 1205 has an inverted "S" shaped cross-section. Both ends of the liquid flow pipe 1205 penetrate the treatment box 1 and extend to its outer surface. The advantage is that the inverted "S" shaped liquid flow pipe 1205 can increase the contact area with the substances in the treatment box 1, prolong the residence time of the heating medium, and improve the heating efficiency.

The water inlet pipe 15 is used to inject the semi-coke wastewater to be treated, and the water outlet tank 14 can collect the treated water for subsequent testing and discharge.
[0041] Working Principle: During use, after the booster pump 4 starts, it pumps methanol from the methanol storage tank 6 into the treatment tank 1 through connecting pipe 5 and connecting pipe 7 to wash the adsorbent. This methanol washing process effectively removes contaminants adhering to the adsorbent surface, restoring its adsorption performance and facilitating subsequent recycling. When the negative pressure extraction component 9 is working, the extraction pump 903 extracts gas from the treatment tank 1 through extraction pipe 902, creating a negative pressure environment in the negative pressure tank 901. This causes easily liquefied products such as water or methanol in the treatment tank 1 to vaporize and be extracted, then discharged through extraction pipe 904 and discharge pipe 905. The negative pressure environment lowers the boiling point of the products, allowing easily liquefied substances to vaporize and separate at a lower temperature, avoiding the impact of high temperatures on the adsorbent's performance, thus obtaining a dry adsorbent. When the heating component 12 is working, it can... The medium in the liquid pipe 1205 is heated, which in turn heats the adsorbent in the treatment tank 1. The heating step can improve the solubility of the solute, accelerate the chemical reaction or adsorption-desorption process, and improve the treatment efficiency of semi-coke wastewater. The control box 2 can centrally control the start and stop of other components. With the extraction pipe 2 904 connecting the extraction pump 903 and the discharge pipe 905, the gas transmission during the negative pressure extraction process can be facilitated. The inverted "S"-shaped liquid pipe 1205 can increase the contact area with the substances in the treatment tank 1, prolong the residence time of the heating medium, and improve the heating efficiency. The slag discharge pipe 13 can periodically remove the impurities precipitated in the treatment tank 1, keep the equipment clean, and avoid the accumulation of impurities affecting the treatment effect. The water inlet pipe 15 is used to inject the semi-coke wastewater to be treated, and the water outlet tank 14 can collect the treated water for subsequent testing and discharge.
