PURPOSE:To remove impurities in hot-water almost perfectly and reduce power for carrying the hot-water remarkably by a method wherein the insides of a carrying pipe and hot-water reserving tower are evacuated by employing a vacuum pump and the hot-water is flushed to obtain steam and carry the steam automatically. CONSTITUTION:When a hot-water supplying pump 2 is operated, the hot-water, extracted, from a production well 1, is supplied into the hot-water reserving tower 3. The inside of the tower 3 is evacuated by the operation of the vacuum pump 6, therefore, the hot-water, supplied here, is flushed and changed into steam, thereafter, is carried automatically and smoothly through a carrying pipe 5 in a form, not including impurities. The hot-water can be carried automatically in the form of steam, therefore, 90-95% of impurities may be removed by remaining them in the hot-water and, further, only the power to operate the vacuum pump is enough to operate the system, therefore, the low- temperature hot-water of 50-60 deg.C may be carried by the 30% of power as compared with the case, wherein the hot-water is transported, because of the expansion of the steam of the hot-water. |
