Description

Technical Field

[0001] The utility model relates to the technical field of waste gas treatment, in particular to a wind-reducing, concentration-enhancing, condensation and recovery device. Background Art

[0002] Organic pollutants in industrial waste gas are usually discharged in low concentrations. Such waste gas is quickly diluted in the atmosphere, resulting in too low a concentration of organic pollutants, making it difficult to effectively collect and treat. Traditional waste gas treatment methods have low condensation efficiency due to the low concentration of organic pollutants. At the same time, in traditional waste gas treatment methods, the treatment equipment consumes a lot of energy and chemicals, and the treatment efficiency is limited by the concentration of organic pollutants. The lower the concentration of organic pollutants in the waste gas, the larger the treatment equipment required and the higher the operating cost. Utility Model Content

[0003] The purpose of the utility model is to provide a condensation recovery device with reduced airflow and increased concentration, which can reduce the exhaust air volume at the air outlet of the production equipment by adjusting the fan frequency and using a regulating valve, thereby reducing airflow and increasing concentration, concentrating organic pollutants, and then condensing and liquefying the concentrated high-concentration organic pollutants through a condenser. As the concentration of organic pollutants increases, the condensation efficiency is improved, and at the same time, reducing airflow and increasing concentration can simplify equipment, save energy and cost.

[0004] In order to achieve the above-mentioned purpose, the utility model provides a condensation recovery device with reduced air flow and increased concentration, comprising:

[0005] Production equipment;

[0006] A fan, wherein the fan inlet is provided with a fresh air inlet pipe, and the fan outlet is connected to the air inlet of the production equipment;

[0007] A condenser, a delivery pipeline is arranged between the condenser inlet and the air outlet of the production equipment, the condenser inlet and the air outlet of the production equipment are connected through the delivery pipeline, and the delivery pipeline is connected to the fresh air inlet pipe.

[0008] Optionally, a first regulating valve is provided on the fresh air inlet pipe, and a second regulating valve is provided on the delivery pipeline.

[0009] Optionally, a third regulating valve is provided at the connection between the delivery pipeline and the fresh air inlet pipe.

[0010] Optionally, the condenser is provided with a condenser tube, and the condenser tube is in a curved and folded shape.

[0011] Optionally, the condenser tubes are arranged in multiple rows, and the condenser tubes in a single row are arranged in a zigzag shape horizontally and / or vertically.

[0012] Optionally, the condenser outlet is a non-condensable gas discharge port.

[0013] Optionally, the air reduction and concentration increase condensation recovery device further comprises:

[0014] A refrigeration unit is connected to the condenser and is used for conveying refrigerant to the condenser.

[0015] The beneficial effects of the utility model are as follows: by adjusting the frequency of the fan and using the regulating valve, the exhaust air volume at the air outlet of the production equipment is reduced, and the organic pollutants are concentrated by reducing the air flow and increasing the concentration, and then the concentrated high-concentration organic pollutants are condensed and liquefied through the condenser. Due to the increase in the concentration of organic pollutants, the condensation efficiency is improved. At the same time, by reducing the air flow and increasing the concentration, the equipment can be streamlined, and energy and costs can be saved. In addition to reducing the speed of the fan, the gas flow rate and flow rate can be reduced by adjusting the first regulating valve, the second regulating valve and the third regulating valve to different degrees to achieve the effect of increasing the concentration of organic pollutants. The concentrated high-concentration organic pollutants enter the condenser and are condensed into a liquid state by lowering the temperature. During the condensation and liquefaction process, due to the high concentration of organic pollutants, the relative humidity may also increase, so the condensation efficiency is improved.

[0022] See also Figure 1 A condensation recovery device for reducing air flow and increasing concentration shown in a preferred embodiment of the present application includes production equipment 1, a fan 2, a condenser 3 and a refrigeration unit 4. The inlet of the fan 2 is provided with a fresh air inlet pipe 5, and the outlet of the fan 2 is connected to the air inlet of the production equipment 1. A delivery pipeline 6 is provided between the inlet of the condenser 3 and the air outlet of the production equipment 1. The inlet of the condenser 3 is connected to the air outlet of the production equipment 1 through the delivery pipeline 6. The outlet of the condenser 3 is a non-condensable gas discharge port 31, and the delivery pipeline 6 is connected to the fresh air inlet pipe 5. The refrigeration unit 4 is connected to the condenser 3 for delivering refrigerant to the condenser 3. A first regulating valve 7 is provided on the fresh air inlet pipe 5, and a second regulating valve 8 is provided on the delivery pipeline 6. A third regulating valve 9 is provided at the connection between the delivery pipeline 6 and the fresh air inlet pipe 5.

[0023] According to the solution of the embodiment of the utility model, since the organic pollutants in industrial waste gas are usually discharged in the form of low concentration, such waste gas is quickly diluted in the atmosphere, resulting in too low concentration of organic pollutants, making it difficult to effectively collect and treat. The traditional waste gas treatment method has low condensation efficiency due to the low concentration of organic pollutants. At the same time, in the traditional waste gas treatment method, the treatment equipment needs to consume a lot of energy and chemicals, and the treatment efficiency is limited by the concentration of organic pollutants. The lower the concentration of organic pollutants in the waste gas, the larger the treatment equipment required and the higher the operating cost.

[0024] Therefore, the present application reduces the exhaust air volume of the air outlet of the production equipment by reducing the speed of the fan 2 and using the regulating valve, reduces the dilution effect of the exhaust gas, makes the organic pollutants more concentrated in the exhaust gas, realizes the concentration of the organic pollutants by reducing the wind and increasing the concentration, and then condenses and liquefies the concentrated high-concentration organic pollutants through the condenser 3. Due to the increase in the concentration of organic pollutants, the condensation efficiency is improved, and at the same time, the equipment can be streamlined by reducing the wind and increasing the concentration, saving energy and cost. When in use, in addition to reducing the speed of the fan 2, the control gas flow rate and flow rate can also be reduced by regulating the first regulating valve 7, the second regulating valve 8 and the third regulating valve 9 to different degrees to achieve the effect of increasing the concentration of organic pollutants. The concentrated high-concentration organic pollutants enter the condenser 3, are condensed into a liquid state by lowering the temperature and discharged through the non-condensable gas discharge port 31. During the condensation and liquefaction process, due to the high concentration of organic pollutants, the relative humidity may also increase, so the condensation efficiency is improved.

[0025] The following is a detailed description with specific embodiments:

[0026] In one embodiment, the condenser 3 is provided with a condensing tube, which is a curved folding shape. The condensing tube is provided with multiple rows, and the condensing tube described in a single row is arranged in a zigzag shape in a horizontal and / or vertical direction. In the present application, by reducing the exhaust air volume of the production equipment air outlet, organic pollutants are more concentrated in the waste gas, thereby improving the concentration of organic pollutants and facilitating the subsequent improvement of the condensing efficiency of the condenser 3. In order to further improve the condensing efficiency, the present application increases the contact area with the organic pollutants in the waste gas by changing the shape of the condensing tube, thereby making the condensing efficiency higher. Specifically, the condensing tube is arranged in a multi-row parallel form, and the rows are interconnected. The single row cooling tube can be arranged in a zigzag shape in a horizontal or vertical direction, and can also be arranged in a zigzag shape in a horizontal and vertical direction, thereby further increasing the condensing efficiency.

[0027] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0028] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
