The invention relates to an abandoned-water-free closed cooling tower and a valve cooling system.The abandoned-water-free closed cooling tower comprises a tower body, a spraying assembly, filler, a coil pipe, an electrochemical descaling device and a conductive part, the tower body is provided with a cooling cavity and a water tank, the spraying assembly is arranged at the top of the cooling cavity in the height direction of the tower body, and the filler is arranged in the water tank; due to the action of the filler, water sprayed out of the spraying assembly forms scale on the filler, and the concentration of ions such as Ca < 2 + >, Mg < 2 + >, OH <-> and HCO3 <-> entering water in the water tank can be reduced. The electrochemical descaling device in water prevents positively charged calcium ions and magnesium ions from scaling on the coil pipe according to the principle that like poles repel each other among electrons, the conductive part with the negative electrode connected between the coil pipes can a
