Inlet air cooling device for gas turbine

The utility model provides an air inlet cooling device for a gas turbine, which belongs to the technical field of air inlet cooling of the gas turbine and comprises a cooling box body, a square air inlet pipe is fixedly connected to the input end of the cooling box body, and a non-woven fabric filter screen is fixedly connected to the inner wall of the square air inlet pipe. The output end of the cooling box body is fixedly connected with a circular air outlet pipe, and at least two water passing pipes are fixedly installed on the inner top wall of the cooling box body. After the atomized cold water cools the air, a large amount of the air can be gathered on the inner wall of the cooling box body, water drops can automatically flow into the water collecting pipe at the moment, then water in the water collecting pipe can automatically flow into the filtering tank body, and the water can be sequentially subjected to impurity removal and filtration through the glass fiber filtering layer and the activated carbon
