An LNG gasifier water spraying system comprises an LNG gasifier, a circulation water pool, a monitor device, a controller and a spraying device. The LNG gasifier is arranged on a base. A water guide trough connected with the circulation water pool is arranged around the base. Heating devices are independently mounted on the side wall and the bottom of the circulation water pool. The monitor devicecomprises a first temperature detector on a water inlet pipe, a second temperature detector in the circulation water pool and a liquid level detector. The controller controls opening and closing of avalve and the heating devices according to transmitted temperature signals and liquid level signals. Multiple water stop layers are arranged in the middle of a heat exchange pipe set on the gasifier.Fins of heat exchange pipes are spirally distributed in different forms. By means of the LNG gasifier water spraying system, heat exchange efficiency is greatly improved, the intelligent control method is adopted, the relation
