Description

Technical Field

[0001] The utility model belongs to the technical field of physical cooling devices for high-heat exhaust gas, and in particular relates to a drip irrigation type physical cooling tower for high-heat exhaust gas from printing and dyeing. Background Art

[0002] The high-temperature exhaust gas physical cooling tower is an industrial equipment mainly used to reduce the temperature of high-temperature gases generated in industrial production processes. This cooling tower transfers the heat in the gas to other media, usually water or air, through physical methods such as heat exchange, to achieve the cooling effect. The working principle of the physical cooling tower is usually based on the following methods: 1. Evaporative cooling: The heat is taken away by the evaporation of water, thereby reducing the temperature of the gas. This is a common cooling method, especially in wet cooling towers; 2. Contact heat dissipation: The high-temperature gas is in direct or indirect contact with the cooling water, and the heat is transferred to the water by heat conduction, and then the water takes away the heat; 3. Convection heat dissipation: The heat is transferred from the high-temperature area to the low-temperature area through the flow of gas.

[0003] The temperature of high-heat exhaust gas in the printing and dyeing industry can be very high, and the specific temperature will vary depending on the process, equipment used and the specific conditions of production. In some cases, the flue gas temperature generated by the printing and dyeing setting machine can exceed 200°C. For example, it is mentioned in that the inlet air temperature of the setting machine can be increased to 120-140°C through the heat exchange system, which means that the temperature of the exhaust gas may be higher before the exchange. Therefore, when recovering heat energy from the printing and dyeing exhaust gas, contact heat dissipation is often used. Usually, solid low-temperature medium is used for heat exchange with waste heat exhaust gas. However, the long-term heat exchange between the solid low-temperature medium and the waste heat exhaust gas leads to a decrease in the efficiency of the cooling device. Conventionally, cold water pipes are used for heat exchange. Cold water pipes are often made of ceramic pipes and metal pipes, but both have obvious defects. Ceramic pipe defects: Because the treatment process of printing and dyeing waste heat exhaust gas often faces a high-temperature and rapid cooling working environment, the ceramic pipe breaks due to rapid thermal expansion and contraction. Metal pipe defects: Since the waste heat exhaust from printing and dyeing contains more corrosive substances, metal pipes are prone to rust, resulting in a short actual lifespan.

[0004] In order to improve the problems that occur in the process of treating printing and dyeing waste heat tail gas with a water cooling pipe, the utility model hopes to provide a drip irrigation type printing and dyeing high-heat tail gas physical cooling tower. Utility Model Content
