From the upper section of the gas of the upper outlet of the gas producer, the upper section of the gas is first used to remove the tar by the electric tar remover, and then cooled to room temperature by the upper section of the gas cooler to remove the condensate water in the gas.The gas then passes through a secondary electric deoiler to remove the light oil and the tar and impurities involved.At this time, the content of impurities in the gas can reach 20mg/Nm3.
The lower section of the gas at the lower outlet of 600-700 ℃, after the dust is removed by the cyclone dust collector, it enters the waste heat boiler to recover sensible heat and produce steam. Finally, it enters the lower section of the gas cooler for indirect cooling to room temperature. The gas is mixed with the upper section of the gas to form a cold clean gas and sent to the user by the gas exhaust machine.
The transmission distance of cold clean gas is long, which is suitable for automatic control and can meet the requirements of desulfurization process.The disadvantage is that the system is complex and the investment is relatively large.Since the tar and light oil are removed and the gas is cooled to room temperature, the thermal efficiency is relatively low, usually 75-78%.When clean gas is needed or cold gas with high calorific value is needed, the cooling gas flow can be adopted.
In China, the technology of gas generator has been leading the development of environmental protection machinery industry.In addition, with the development of social economy, the development of China's machinery industry has made great progress, the development of gas generator is the most prominent.With the development of coal gas generator technology, its related industries have also made progress, raw material selection and drying technology have reached a relatively high level.With the development of gas generator, its application scope is becoming more and more extensive, more and more materials will use gas generator.For the gas generator, this is an opportunity for the development of gas generator, and it is also an opportunity for the development of other industries.
High quality gas producer furnace is made of very thick steel plate, very heat resistant, very strong resistance, can greatly improve the service life of the gas producer furnace.The biggest advantage of gas generator can make full use of coal, let coal get full combustion, improve the efficiency of gas generator will not produce coal waste.The dust removal device in the gas generator furnace can remove the dust in the furnace, so that the exhaust gas produced by the gas generator furnace can meet the national emission standards, will not pollute the atmospheric environment, fully in line with the national strategy of green economic development.
The company has long been engaged in the design, manufacture, installation, commissioning and other technical services of two-stage gas generator and gas generator.Contact number: 86-13676907460
