Description

Technical Field

[0001] This utility model relates to the field of dust removal and environmental protection technology, specifically to a flue gas purification device with adjustable spray heads. Background Technology

[0002] Industrial production processes generate large amounts of flue gas containing various pollutants, such as sulfur dioxide, nitrogen oxides, and particulate matter. If these flue gases are directly released into the atmosphere, they will cause serious harm to the environment and human health. Therefore, the application of flue gas purification equipment is crucial. Currently, many flue gas purification devices use a spraying process, in which absorbent liquid is sprayed into the flue gas through spray heads to achieve full contact between the gas and liquid phases, thereby removing pollutants from the flue gas. However, the spraying range and angle of traditional spray heads are generally fixed, making it impossible to easily clean the inside of the equipment.

[0003] A search revealed existing technology (application number: 201811556527.7), which describes "a flue gas purification and treatment device." This utility model discloses a flue gas purification and treatment device, comprising a flue gas inlet pipe, an electrostatic precipitator, a bag filter, and an agglomerating liquid atomizing spray mechanism. One end of the flue gas inlet pipe is a flue gas inlet, and the other end is connected to and communicates with the inlet flue of the bag filter. The electrostatic precipitator is installed inside the flue gas inlet pipe. The agglomerating liquid atomizing spray mechanism has an atomizing spray head located inside the inlet flue, and is used to spray atomized agglomerating liquid into the inlet flue through the atomizing spray head. A tail gas processor is connected to the clean flue gas outlet of the bag filter.

[0004] However, while existing technologies have improved overall convenience, facilitated overall maintenance, and enhanced the practicality of structural design, thereby improving overall purification efficiency, they still have some shortcomings: the equipment structure is complex and costly, containing multiple components; operating energy consumption and maintenance costs are high, the replacement costs of internal electrostatic dust removal, filter bags, and activated carbon filters are high, and convenient cleaning functions are lacking.

[0042] Example 2:

[0043] Based on Example 1, in order to further increase the coverage area of ​​the spray liquid, a spray assembly is arranged inside the purification box 2;

[0045] In a preferred embodiment, the fixed pipe 10 is made of stainless steel and is cylindrical; the longitudinal pipe 11 is made of stainless steel and is cylindrical; the conveying pipe 22 is made of stainless steel and is cylindrical; the transverse pipe 12 is made of stainless steel and is rectangular tubular, distributed in parallel; the rotating pipe 13 is made of stainless steel and is cylindrical; and the spray head 14 is made of copper and is trumpet-shaped. The spray assembly transmits the spray liquid delivered by the water pump 8 to the spray head 14 through the various pipes.

[0049] The channel enables the circulation of the spray liquid. The water pump 8 transports the spray liquid to the spray head 14 through the conveying pipe 22, etc. The waste liquid after spraying flows back to the water tank 1 through the guide plate 30, improving the utilization rate of the spray liquid and performing preliminary cleaning of the inside of the device.
