There is a certain amount of sulfur in the plate heat exchanger, and the sulfur will pollute the environment. Therefore, it is necessary to desulfurize the heat exchanger. What desulfurization principles are used?
The desulfurization of the phe can not only recover the heat of the high-temperature flue gas, save energy, but also ensure the normal operation of the desulfurization tower, reduce the water consumption. Improve the desulfurization efficiency of the desulfurization tower and reduce the secondary pollution to the atmosphere.
The heat exchanger has a rectangular outer casing, and the interior is composed of single plate heat exchangers, which may be arranged in a staggered triangular arrangement or in a square arrangement. A tube sheet is placed in the center of the rectangular housing to divide the housing into two parts, forming a passage for high temperature fluid and cryogenic fluid.When the high and low temperature fluids flow through the respective channels at the same time, the heat exchanger transfers the heat of the high temperature fluid to the low temperature fluid, thereby achieving heat exchange between the two fluids, so that the original flue gas temperature is lowered to reach the absorption tower temperature . The temperature rise of the net flue gas meets the emission requirements.
The number of plate heat exchangers depends on the amount of heat exchange. In order to increase the heat transfer coefficient, the fins are wound on the heat exchanger, so that the number of heat exchangers required can be greatly reduced.
In addition to heat transfer, the plate heat exchanger can also be used for desulfurization. It is an energy-saving and environmentally-friendly device that uses the principle of desulfurization to achieve environmental protection and meet corresponding requirements.
