Embodiment Construction
[0034] The specific embodiment of the present invention will be further described below in conjunction with accompanying drawing:
[0035] See Figure 1-Figure 3 As shown, a dust-containing exhaust gas purification device related to the present invention includes a bottom plate 1, a cylinder body 3, a flange 9, a flange cover 10, a washing liquid nozzle 4, a downcomer 5, a spoiler 7, an annular baffle The liquid plate 8, the ammonium sulfate tail gas inlet pipe 11, the annular groove 13 and the support plate 14, the bottom plate 1, the cylinder body 3 and the flange 9 are sequentially welded and connected to form the equipment shell, and the lower left side of the cylinder body 3 is provided with a liquid discharge port 2. The lower part of the right side is located higher than the discharge port 2. There is a full flow port 6. The upper part of the right side is provided with an exhaust gas outlet 12; the exhaust gas inlet pipe 11 is welded to the flange cover 10 and passes t...

The invention relates to a device and a technology for purifying dust-containing tail gas. The device comprises a bottom plate, a barrel, a flange, a flange cover, a washing liquid spray pipe, a downcomer, a turbulent flow barrel, an annular liquid baffle, an ammonium sulfate tail gas inlet pipe, an annular groove and a supporting plate. The washing liquid spray pipe can perform three-stage spraycleaning on the ammonium sulfate tail gas from the ammonium sulfate tail gas inlet pipe from top to bottom, and the annular liquid baffle can perform water-mist separation on the cleaned tail gas containing water mist. The device and the technology have the following advantages: 1) three-stage jet washing at different positions and angles effectively avoids dust escape and remarkably improves thedust purification capacity; 2) the design is optimized, and the heights of the bottom of the ammonium sulfate tail gas inlet pipe and the liquid level are kept, so the phenomenon that the resistance is increased due to the fact that the section of airflow changes too much is avoided; 3) the liquid receiving area of the annular groove can receive a liquid flowing down from the annular liquid baffle, so the separated liquid is prevented from being secondarily carried by gas; and 4) the device has a simple structure, and is convenient to operate.
Description
technical field [0001] The invention relates to the ammonium sulfate tail gas treatment technology in the coking technical field, in particular to a dust-containing tail gas purification device and process. Background technique [0002] In my country's coking industry, the semi-direct ammonium sulfate production process is mainly used at this stage, and the spray saturator is used as the core equipment to produce ammonium sulfate. The tail gas produced by drying the ammonium sulfate is sent to the exhaust gas cleaning tower to remove the ammonium sulfate dust, and then the liquid in the tail gas is removed through the mist separator and then discharged. With the expansion of production scale, the purification capacity of the exhaust gas cleaning tower is insufficient, and a large amount of ammonium sulfate dust is carried by the exhaust gas into the atmosphere, polluting the environment. Contents of the invention [0003] In order to overcome the defects of the existing t...
