Device for automatically adjusting ventilation quantity of cooling tower

Abstract

The invention provides a device for automatically adjusting the ventilation quantity of a cooling tower. A supporting plate comprises an upper plate and a lower plate which are positioned at the upperend and the lower end of a tower body ventilating opening of the cooling tower; the upper plate and the lower plate are connected with the tower body of the cooling tower in a sealed manner respectively; a plurality of rotating shafts are uniformly distributed on the supporting plate; a vertical louver board is fixedly arranged on each rotating shaft; the rotating shafts are connected with the output end of a transmission device; the input end of the transmission device is connected with the output end of a motor; a cooling water temperature sensor is positioned in cooling water in the cooling tower; the motor is connected with a control device; the output end of the cooling water temperature sensor is connected with the control device. The device for automatically adjusting the ventilation quantity of the cooling tower has the beneficial effects as follows: the device for automatically adjusting the ventilation quantity of the cooling tower can monitor whether the temperature of thecooling water meets a set value in real time or not and adjust the opening and closing angle of the vertical louver board in real time according to the situation so as to adjust the air intake of thetower body ventilating opening, does not need manual participation in the whole process, has high degree of automation, does not frequent detachment and mounting, saves manpower and material resources, has low overall production cost, and is suitable for popularization.

Description

technical field [0001] The invention relates to the technical field of cooling and heat dissipation equipment, in particular to an automatic adjustment device for ventilation volume of a cooling tower. Background technique [0002] A cooling tower is a device that dissipates waste heat generated in industrial production or refrigeration processes into the atmosphere. Its own heat dissipation method is usually natural ventilation. Due to the different wind speed and direction in the natural environment, its own heat dissipation is also changing all the time. . Especially in industrial waste heat recovery and utilization projects, in addition to the constant changes in outdoor wind conditions, the heating load of the system also changes. Therefore, when the heat absorbed by the heat pump changes, the heat dissipation of the cooling tower itself must be adjusted to ensure the total heat dissipation of the cooling tower. (The heat pump absorbs heat + the heat dissipation of the...
