Description

Technical Field

[0001] The utility model relates to the technical field of sulfuric acid dilution coolers, in particular to a sulfuric acid dilution cooler. Background Art

[0002] Sulfuric acid is the most active binary inorganic strong acid and can react with most metals. During the dilution process, sulfuric acid needs to react with water for dilution, but when mixed with water, it releases a lot of heat energy. Therefore, an acid dilution cooler is needed to reduce the dilution temperature when diluting sulfuric acid.

[0003] According to the description of a sulfuric acid dilution cooler disclosed in the patent website (authorization announcement number: CN 218307775 U), "The utility model relates to the technical field of chemical equipment, and discloses a sulfuric acid dilution cooler, including a barrel, a dilution chamber and a transition chamber are arranged inside the barrel, a plurality of groups of liquid flow holes are equidistantly arranged at the bottom of the dilution chamber, a liquid flow tube is fixedly connected to the inner wall of the liquid flow hole, the bottom end of the liquid flow tube passes through the top of the transition chamber and is connected to the inner cavity of the transition chamber, an exhaust hole is arranged at the top of the dilution chamber, and an exhaust pipe is fixedly installed on the inner wall of the exhaust hole. The sulfuric acid dilution cooler, by arranging a cooling pipe and a shunt pipe, allows the cooling water to flow to different positions inside the barrel after passing through the cooling pipe and the shunt pipe, thereby improving the cooling effect provided by the cooling water to the dilution chamber and the transition chamber, and a connecting pipe is arranged to realize the connection between the transition chamber and the discharge pipe, so that the cooling water contacts the connecting pipe when flowing inside the barrel and provides cooling for the sulfuric acid inside the connecting pipe, thereby improving the cooling efficiency of the device."

[0005] During use, the utility model allows cooling water to flow to different positions of the cylinder body through the cooling pipe and the shunt pipe, providing cooling for dilution. The design of the guide plate and the return plate allows the cooling water to be circulated. However, in actual use, the cooling water will take away heat when cooling the sulfuric acid dilution, causing the cooling water to heat up. After the cooling water circulates back to the cooling water tank, the temperature of the cooling water continues to rise because the temperature fails to decrease, resulting in a continuous decrease in the cooling effect on the sulfuric acid dilution. Therefore, it is necessary to improve a sulfuric acid dilution cooler to solve the above problem. Utility Model Content
