[0002] Inorganic pretreatment experiment is an important experimental process of physical and chemical testing experiment. This experiment will use a large amount of strong acid and alkali with high concentration, accompanied by high-temperature evaporation. The acid and alkali are mixed with high-temperature air and discharged at high altitude through the exhaust system. At present, most laboratory buildings are multi-story buildings with long exhaust ducts. The acid and alkali waste gas quickly condenses into liquid and drips onto the ceiling along the flange joints of the ventilation duct and condenses into the inside of the fume hood, damaging the ceiling and seriously affecting the normal progress of the experiment. This phenomenon has troubled laboratory builders and experimental operators for many years. In order to solve this problem, laboratory builders or manufacturers have taken many measures such as installing similar condensation tank devices. Domestic products have taken the installation of water spray devices in the ventilation ducts, which is difficult to operate. These measures have not achieved the desired effect;

[0003] The phenomenon of laboratory waste liquid condensation seriously troubles the safe operation of experimenters, often leading to contamination of test samples and forcing the experiment to be terminated. When multiple measures fail, users can only reduce the test samples and experimental time, sacrificing the experimental results, resulting in very low experimental efficiency. In addition, the existing exhaust device is easily damaged by the erosion of such strong acid and alkali exhaust gas, and the existing exhaust condensation device is not easy to replace, clean and repair.

At the same time, under the action of the slot 19 and the slide block 21, it is convenient for the staff to take out the filter screen 1, so as to perform regular cleaning to ensure the filtering effect of the filter screen 1;

[0027] A condensation assembly 25 is correspondingly arranged on the inner side of the box body 3, and a sealing ring 17 is arranged at the connection between the condensation assembly 25 and the box body 3. By providing the sealing ring 17, the sealing performance of the connection between the condensation assembly 25 and the box body 3 can be ensured to prevent the exhaust gas from leaking out;

[0028] A condensing pipe 14 is provided at the lower end of the condensing assembly 25, a condensing box 13 is provided at one end of the box body 3, a liquid inlet pipe 10 is provided through the upper end of the condensing box 13, the other end of the liquid inlet pipe 10 is provided inside the condensing assembly 25, a water pump 11 is provided in the middle of the liquid inlet pipe 10, a liquid outlet pipe 12 is provided through the other end of the condensing box 13, the other end of the liquid outlet pipe 12 is also provided inside the condensing assembly 25, and the condensed water inside the condensing box 13 can enter the liquid inlet pipe 10 and then enter the condensing pipe 14 by starting the water pump 11, and the circulating condensation and transportation of the condensed water can be realized by providing the liquid outlet pipe 12, and similarly, corresponding cooling components are provided inside and outside the condensing box 13, so as to ensure that the condensed water always maintains the condensation effect during the circulation process;

[0029] A drain pipe 15 is provided through the bottom of the box body 3, and a liquid collecting box 6 is provided correspondingly below the box body 3. A drain head 16 is provided at one end of the liquid collecting box 6.

The filter 1 inside the box body 3 can filter the exhaust gas, thereby filtering the impurities in the exhaust gas to prevent it from sticking to the inner wall of the pipe and being difficult to clean during subsequent discharge. At the same time, the exhaust gas encounters the condenser tube 14. Due to the low temperature of the condenser tube 14, the exhaust gas condenses to form small water droplets, which drip into the inside of the drain pipe 15 and then flow into the collecting tank 6. When it is necessary to disassemble, replace and clean the condensation component 25, the pins 24 at both ends can be pulled outward, and the staff can pull the handle 8 above to pull the condensation component 2 out of the box body 3, which is convenient for cleaning and replacing the condensation component, avoiding the erosion of strong acid and alkali exhaust gas after long-term use and causing the condensation function to fail, thereby improving safety.
