Description

Technical Field

[0001] The utility model relates to the technical field of air purification equipment, in particular to a device used for purification of nitrogen oxides. Background Art

[0002] There are many types of nitrogen oxide waste gas, such as nitrous oxide, nitric oxide, nitrogen dioxide, nitrogen trioxide, nitrogen tetroxide and nitrogen pentoxide, but mainly nitric oxide and nitrogen dioxide, which are common air pollutants. Nitrogen oxide waste gas belongs to the most difficult N0x among many waste gases to manage, and is the main culprit of air pollution. With the development of urban modernization and the increase in the number of motor vehicles, the impact of road vehicle exhaust emissions on the environment has become increasingly prominent. Among them, nitrogen oxides, as the precursor of photochemical smog, are directly discharged into the air without treatment, causing public harm to the lives of surrounding residents and the ecological environment.

[0003] The current nitrogen oxide purification treatment equipment refers to a nitrogen oxide purification device disclosed in application number CN202121336497.6. Through the molecular sieve plate set in the main body of the device, it can effectively adsorb the chemical substances in the exhaust gas, so that the exhaust gas is filtered more fully, and the molecular sieve plate is not directly welded in the main body of the device. The molecular sieve plate can be installed and disassembled at any time. When the molecular sieve plate needs to be replaced, it is only necessary to loosen the fixing bolts in the mounting seat to easily disassemble the molecular sieve plate, and the installation is also convenient and quick. It can be seen that the system composition of the current nitrogen oxide purification treatment equipment is diverse and complex, and in order to achieve the purpose of convenient equipment disassembly and installation, many ingenious switches for auxiliary disassembly and assembly will be set, but it must be taken into account that the auxiliary switch also has losses in daily use, and also involves later maintenance. Therefore, the existing nitrogen oxide purification treatment equipment is not only complex in structure but also has too many auxiliary facilities for disassembly and assembly, which brings about great maintenance difficulties and increased maintenance and management costs.

[0004] Therefore, in view of the above situation, there is an urgent need to develop a device for purifying nitrogen oxides to meet the needs of practical use. Utility Model Content
