With the improvement of economic level, people pay more and more attention to environmental protection. In future economic development, economic benefits must be given top priority. As a major coal consumer in China, whether coal can be used environmentally is very important for environmental protection. As an energy-saving, efficient and environmentally friendly way to utilize coal, gasifiers are undoubtedly an effective tool for environmental protection in the future. The gas produced by the two-stage gas generator is relatively pure and has made great contributions to environmental protection. Its sales volume ranks first among environmental protection equipment.
As a kind of coal gasification equipment, gasifier has a history of hundreds of years. China's industrialization is moving towards“Smoke-free”、“green”, the times have come to support environmental protection, and the accelerated development of urbanization, industrialization, and informatization have made environmental pollution work more difficult, and gas generators are even more difficult.“of great importance”A warrior. The gas produced by the two-stage gas generator is relatively pure and has made great contributions to environmental protection. Its sales volume ranks first among environmental protection equipment.
Double-stage gas generator gas transmission process:
Two-stage gas generatorThe generated gas is divided into upper section gas and lower section gas. The upper section gas goes to a Class I electric tar collector to remove heavy tar and dust. Its working temperature is between 90~150℃, and then enters the indirect cooler, where the gas is cooled to about 35~45℃. The lower section gas is dusted by the cyclone dust collector, and the temperature after dust removal is about 450~550℃. Then it enters the waste heat heat exchanger, which cools the gas while recovering the sensible heat of the gas. The gas temperature drops to about 200~230℃; then it enters the air cooler for cooling, and the temperature drops to 65~80℃. Through the indirect cooler, the circulating cooling water is indirectly cooled to 35~45℃. After being indirectly cooled, the upper section gas and lower section gas enter the II-level electric light oil collector to be deoiled and dusted again. The cooled and purified gas is pressurized and transported through gas pipelines for use.
In the next five years, the two-stage gas generator will become a substitute for the single-stage gas generator. In terms of improving gas utilization, the gasification intensity of the single-stage gas generator is relatively low. In the process of making gas, coal tar will be produced, and the generated coal tar will be mixed with the dust in the gas. In this way, the scope of application of the single-stage gasifier is determined without dust removal. Since the coal tar mixture easily precipitates and blocks the pipes, if the use environment does not require purification, the single-stage gasifier is more suitable for places with short transmission intervals, such as kilns and industrial furnace industries.
As the demand for environmental protection increases, two-stage gas generators will surely replace single-stage furnaces. In many years, better and more environmentally friendly technologies will replace two-stage furnaces. As a member of the coal gas industry, Jinan Huangtai Gas Furnace must continue to make progress, insist on innovation, and move forward firmly on the road of environmentally friendly coal gas technology!
