Whitening Heat Exchanger

The boiler flue gas whitening heat exchanger is an all-welded plate bundle. By cooling the slurry, the temperature and humidity of the flue gas in contact with the slurry are reduced, and the discharge of desulfurization salts in the chimney is reduced. Combined with the flue gas heater, the flue gas whitening is achieved. Effect. It is widely used in flue gas dewhitening process systems in electric power, iron and steel, coking and other industries. This product is also suitable for slag-water heat exchange in the iron and steel industry, and slurry cooling in the alumina industry.
The working principle of boiler flue gas whitening heat exchanger: The fresh air and the exhaust gas pass through the heat exchanger, the two air flows do not meet directly, and the energy will be transferred from the upper side to the lower side to achieve the purpose of energy recovery. The fresh air and exhaust air are completely separated by the heat conduction plate to avoid cross contamination and ensure the cleanliness of the fresh air. Used for boiler flue gas cooling and energy recovery. Supply air and exhaust air are completely separated, and two adjacent aluminum foils form a channel for fresh air or exhaust air flow. When the airflow crosses through the channels, heat will be transferred and fresh air and exhaust air will be completely separated. The boiler flue gas whitening heat exchanger is installed in the boiler exhaust system. During the exhaust process, the exhaust gas and the fresh air exchange heat through the heat exchange core. The heat of the exhaust gas is used to pretreat the fresh air and increase the temperature of the incoming air. It can also be used for The exhaust gas treatment of the paint baking room, and the increase of the air supply temperature of the ventilation system in the room, etc., so as to achieve the purpose of energy recovery.
Features of whitening heat exchanger: 1. Energy saving and consumption reduction. The whitening heat exchanger does not require external force for heat exchange, is relatively energy-saving, and has low operating costs. 2. Stable operation, no moving parts, easy maintenance. The heat exchange is the phase change heat transfer in the tube, and the equipment is directly flue. 3. High and low temperature flue gas zero wind. Because we use full welding between the middle orifice plate and the heat pipe. No mixed wind, to ensure our role in desulfurization. 4. High heat exchange efficiency. The evaporating end and the condensing section of the whitening heat exchanger are integrated into one piece of equipment. In order to avoid heat loss during the heat exchange process. The working fluid can design the steam start-up temperature according to the working conditions to reduce the heat waste in the working fluid. Its heat absorption, heat transfer and heat dissipation performance ensures that the low temperature flue gas can be heated up relatively high, and the whitening effect is relatively good. 5. Treatment of ash accumulation and dirty gambling: In the working conditions where the flue gas contains dust and ammonia gas is relatively large, we add a soot stopper at the inlet of the high temperature flue gas, and choose different soot blowers according to the working conditions. Below the equipment, keep the ash hopper, the ash outlet, and the ash cleaning door on both sides of the equipment.
