Description

Technical Field

[0001] The utility model relates to the technical field of cooling towers, in particular to a cooling tower with bamboo lattice fillers. Background Art

[0002] A cooling tower is a device that uses water as a circulating coolant to absorb heat from a system and discharge it into the atmosphere to lower the water temperature. It uses the heat exchange between water and air flow to generate steam, and the steam evaporates and takes away the heat to achieve the principles of evaporative heat dissipation, convection heat transfer and radiation heat transfer to dissipate the waste heat generated in industry or refrigeration and air conditioning to lower the water temperature. The device is generally barrel-shaped, hence the name cooling tower.

[0003] The working mode of the cooling tower is usually to spray hot water on the bamboo lattice filler, and the airflow generated by the fan takes away the heat of the hot water on the bamboo lattice filler, thereby achieving cooling and cooling. The cooled water falls into the recovery pool under the action of gravity. After long-term use, the surface of the bamboo lattice filler is prone to accumulate impurities and dirt in the water, which will reduce the service life of the bamboo lattice filler. After long-term use, the inner wall of the recovery pool is prone to accumulate impurities and algae, which is easy to pollute the environment. The existing cooling tower is not convenient for uniform spraying when spraying hot water, which affects the cooling efficiency. Therefore, a bamboo lattice filler cooling tower is proposed.

Through such a setting, it is convenient to clean the inner wall of the recovery pool, prevent the deposition of debris on the inner wall of the recovery pool to produce algae, and prevent environmental pollution.

[0033] like Figure 1-Figure 4 As shown, an air intake cylinder 19 is fixedly connected to the bottom of the cooling cylinder 17, a recovery pool is fixedly connected to the bottom of the air intake cylinder 19, a drainage pipe 21 is fixedly connected to the bottom of the recovery pool, four legs 20 are fixedly connected at equal intervals below the recovery pool, and the scraper 6 abuts against the inner wall of the recovery pool.

The fixed cage 7 is no longer subjected to the downward force but is pushed upward by the second spring 23. The fixed cage 7 drives the bamboo lattice filler 24 to move upward. As the electric push rod 14 is repeatedly pushed, the bamboo lattice filler 24 repeatedly moves up and down to achieve vibration, and the vibration causes the impurities and dirt on the surface of the bamboo lattice filler 24 to fall off.
