Description

Technical Field

[0001] This utility model relates to the field of waste gas treatment technology, specifically a waste gas treatment condensation and recovery device. Background Technology

[0002] Waste gas treatment refers to the process of purifying waste gas emitted during industrial production, energy utilization, transportation, etc., through physical, chemical, or biological methods to reduce or eliminate harmful substances (such as particulate matter, gaseous pollutants, odors, etc.) so that it meets national or local environmental protection standards before being discharged, thereby protecting the atmospheric environment and human health.

[0003] Condensation recovery technology in waste gas treatment is a method that achieves pollutant separation and resource recovery by lowering the temperature of waste gas, causing condensable components (such as volatile organic compounds (VOCs), solvent vapors, water vapors, etc.) to condense into liquid after reaching a saturated state.

[0004] When the temperature of exhaust gas is too high, direct condensation and recovery through the condenser will result in a heavy load on the condenser, which is prone to damage. At the same time, the condensed gas is discharged after being sprayed, and the water generated by the spraying is discharged without being purified, which will also cause environmental pollution. Therefore, an exhaust gas treatment condensation and recovery device is proposed to solve the above problems. Utility Model Content

It solves the problem that when the temperature of waste gas is too high, direct condensation and recovery through the condenser will result in a large load on the condenser and easy damage. At the same time, the condensed gas is discharged after being sprayed, but the water generated by the spraying is discharged without being purified, which will also cause environmental pollution.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a waste gas treatment condensation and recovery device, including a cooling box, a purification box installed outside the cooling box, and a recovery structure fixedly installed outside the cooling box;

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-5 The waste gas treatment condensation and recovery device in this embodiment includes a cooling box 1, a purification box 4 installed on the outside of the cooling box 1, and a recovery structure 5 fixedly installed on the outside of the cooling box 1.

[0024] The recycling structure 5 includes a temperature sensor 501. The temperature sensor 501 is fixedly installed inside the cooling box 1. A drain pipe 502 is fixedly installed at the bottom of the cooling box 1. A water tank 503 is fixedly installed outside the drain pipe 502. An outlet pipe 504 is fixedly installed at the top of the water tank 503. Valves 505 are fixedly installed outside both the drain pipe 502 and the outlet pipe 504. A spray pipe 506 is fixedly installed inside the water tank 503. A water pump 507 is fixedly installed outside the spray pipe 506. A spray head 508 is fixedly installed inside the purification box 4. A dust filter 509 is fixedly installed at the ventilation opening on the right side of the purification box 4. A discharge pipe 510 is fixedly installed at the bottom of the purification box 4. A purification plate 511 is inserted into the discharge pipe 510.

[0025] exist Figure 2 In the middle, the temperature sensor 501, such as a thermocouple, thermistor, RTD or integrated digital sensor, monitors the water temperature in real time and converts the temperature signal into an electrical signal voltage / current / digital signal. When the temperature exceeds the limit, the controller outputs a switching signal, and the driver converts the controller's electrical signal into mechanical force or fluid pressure to drive the valve 505 to open or close or adjust the opening degree.

[0026] exist Figure 2 In the process, after the purified water inside the cooling box 1 is discharged, it is necessary to manually add purified water back into the cooling box 1 through the water inlet. The heat exchange can be completed when the gas flows by the contact between the purified water and the outer wall of the heat exchange tube 2.

[0027] exist Figure 4In the process, one of the two purification plates 511 contains a polypropylene meltblown filter element. The purification plate 511 forms a multi-layer gradient pore structure through the meltblown process to intercept particles of different sizes. The other purification plate 511 uses the porous structure of activated carbon to adsorb dissolved organic matter, residual chlorine and some heavy metals, thus completing the purification of wastewater.

[0028] During implementation, the following steps are performed: When in use, the exhaust gas enters the cooling box 1 through the left end of the heat exchange tube 2. Low-temperature pure water is added into the cooling box 1 through the water inlet. The exhaust gas enters the condenser 3 for condensation. The liquid produced by condensation enters the water tank 503 through the liquid outlet pipe 504, while the gas enters the purification box 4. The water in the water tank 503 is pumped to the spray head 508 by the water pump 507 to spray the gas and complete the discharge.

[0029] In summary, this waste gas treatment condensation and recovery device allows waste gas to enter the cooling box 1 through the left end of the heat exchange tube 2. Low-temperature pure water is added to the cooling box 1 through the water inlet. As the waste gas flows through the heat exchange tube 2, it exchanges heat with the pure water, lowering the temperature of the waste gas. The waste gas then enters the condenser 3 for condensation. The condensed liquid enters the water tank 503 through the liquid outlet 504, while the gas enters the purification box 4. A water pump 507 pumps the water from the water tank 503 to the spray head 508 to spray the gas, thus completing the discharge process. Temperature sensing is also included. Device 501 monitors the temperature inside the cooling box 1. When the temperature is too high, valve 505 is opened, and pure water flows into water tank 503 for subsequent spraying. The wastewater generated after spraying is purified by two purification plates 511 before being discharged. This solves the problem that when the temperature of the exhaust gas is too high, directly condensing and recovering it through condenser 3 will cause the condenser 3 to be overloaded and easily damaged. At the same time, the condensed gas is discharged after spraying, but the water generated by spraying is discharged without being purified, which will also cause environmental pollution.
