蒸發(fā)式冷凝器系列
蒸發(fā)式冷凝器工作原理
蒸發(fā)冷凝器以水和空氣作為冷卻劑它主要利用部分水的蒸發(fā)帶走工藝介質冷凝過程放出熱量它的外殼為一個薄鋼板和長方形精體內有冷凝排管組、淋水裝皿、收水器底部設集水盤箱體外部設循環(huán)水泵箱體頂部裝有軸流風機蒸發(fā)冷凝器工作時冷卻水由水泵送到冷凝排管上部的噴嘴均勻地噴淋在冷卻器外表面形成一層很薄的水膜高溫工藝介質從冷凝排管上部進入被冷凝后的液體從下部流出噴淋到冷凝排管上的水吸收了高溫工藝介質的熱量后一部分蒸發(fā)變成水蒸汽其余落在下部集水盤內供水泵循環(huán)使用風機強制空氣以3-5m/s速度通過冷凝排管促進水膜蒸發(fā)強化冷凝管外放熱并使吸熱后的水滴在落下過程中為空氣所冷卻蒸發(fā)過程中未被氣化的水滴經上部收水器后回落到下部水箱中以減少水的消耗當
此外水箱內還設浮球閥當水不斷地蒸發(fā)消耗水箱中的水水位過低時浮球閥就自動打開補充冷卻水。
The evaporative condenser uses water and air as a coolant. It mainly uses some water to evaporate and removes the process medium. The condensation process releases heat. Its outer casing is a thin steel plate and a rectangular body with a condensing pipe group, a watering vessel, and a water collector. The bottom of the water collecting tray body is provided with an axial flow fan on the top of the circulating water pump box. The evaporating condenser is installed. The cooling water is sprayed by the pump to the upper part of the condensing pipe. The nozzle is evenly sprayed on the outer surface of the cooler to form a thin layer. The water film high-temperature process medium enters the condensed liquid from the upper part of the condensing pipe and flows from the lower part to the water discharged from the lower part of the condensing pipe, absorbs the heat of the high-temperature process medium, and then partially evaporates into water vapor and the rest falls on the lower water collecting tray. The internal water supply pump uses a fan to force air to pass through the condensing pipe at a speed of 3-5 m/s to promote evaporation of the water film to strengthen the heat release outside the condenser tube, and the water droplets after the heat absorption are cooled by the air during the evaporation process. The water droplets fall back into the lower tank through the upper water collector to reduce water consumption.
In addition, a float valve is arranged in the water tank. When the water is continuously evaporated, the float valve automatically opens the supplementary cooling water when the water level in the water tank is too low.

一般濕球溫度比干球溫度低6-8C這就意味著在同樣環(huán)境條件下使用蒸發(fā)冷凝器可使冷凝系統(tǒng)它是一次性直接向環(huán)境空氣排熱可使系統(tǒng)和壓縮機節(jié)能20％以上運行費用低壽命長維修費用低蒸發(fā)冷凝器全為不銹鋼或鍍鋅鋼管熱漫鋅運行時間長維修成本很低節(jié)水水冷式冷凝器1Kg冷卻水能帶走4.6-6.9W的熱量而1Kg水在常壓下蒸發(fā)能帶走76W熱量因而蒸發(fā)式冷凝器理論耗水量僅為一般水冷式冷凝器的5％10因而它特別適于缺水地區(qū)。
Generally, the wet bulb temperature is 6-8C lower than the dry bulb temperature. This means that using the evaporative condenser under the same environmental conditions can make the condensing system discharge heat directly to the ambient air at one time, which can save more than 20% of the system and compressor energy. Low cost, long life, low maintenance cost, evaporative condenser, all stainless steel or galvanized steel pipe, hot diffused zinc, long running time, low maintenance cost, water-saving, water-cooled condenser, 1Kg of cooling water can take away 4.6-6.9W of heat and 1Kg of water is often used. The evaporation can take away 76W of heat and the theoretical water consumption of the evaporative condenser is only 5% of that of a typical water-cooled condenser. It is therefore particularly suitable for water-deficient areas.
