Problems solved by technology

At the same time, due to the deposition of impurities in the gas, it is found that the heat exchange tubes are often blocked in actual use, which seriously affects the continuous production of gas, resulting in high cost of gas equipment and production costs

Embodiment Construction

[0032] The concrete steps of the two-stage furnace gas purification and cooling process of the present invention are as follows:

[0033] a. The upper gas enters the electric tar catcher to remove heavy tar and dust to obtain purified crude gas;

[0034] b. The gas in the lower section is passed through the cyclone to remove the large particles of dust in the gas, and enters the air cooling tower for cooling, and the preheated air is sent to the two-stage gas furnace;

[0035] c. After the gas obtained from the upper section and the lower section is mixed, it enters the next-stage electric tar catcher to further remove tar impurities, pressurized by the gas booster, and then passes through the drop catcher to remove moisture and transport it to the user .

[0036] The preheated air in step b is sent into the two-stage gas furnace, which can be induced draft type: cold air first passes through the air cooling tower, and after heat exchange, it is introduced into the gas furnac...

Abstract

The invention relates to gas purifying and cooling process and equipment, in particular to gas purifying and cooling process and equipment of a two-section furnace. The gas is cooled by an induced air or blast type air cooling tower instead of a tube air cooling tower and an intercooler in the traditional gas cooling and purifying process, and the preheated air enters a gas furnace. Because the intercooler and a softened water supplying, returning and cooling system thereof are eliminated, the equipment manufacture cost and the maintenance cost of the whole process system are greatly reduced; the preheated air enters the gas furnace, thereby strengthening the gasification process of coal, improving the output of the coal and reducing energy loss; the induced air or blast type air cooling tower has a large heat transfer coefficient, reinforced convection heat transfer and good cooling effect; meanwhile, the volume and the weight of the induced air or blast type air cooling tower are reduced, and the equipment investment is lowered.

Description

technical field [0001] The invention relates to a gas purification and cooling process and equipment, in particular to a two-stage furnace gas purification and cooling process and equipment. Background technique [0002] The two-stage gas generator is widely used in the production of industrial fuel gas, including machinery, metallurgy, non-ferrous metal smelting, glass, ceramics, silt and other industries. The two-stage furnace is a fully gasified gas generator. It adds a dry distillation section to the upper part of the gasification section of the ordinary single-stage atmospheric fixed-bed gas generator, so that the gas furnace includes a gasification section (lower section) and a dry distillation section ( Upper section) two sections, each with a gas outlet. The gas from the two outlets contains impurities such as dust and tar, the gas tar from the dry distillation section is more, and the gasification section has more dust, which requires cooling and purification.
