Description
Technical Field
[0001] The utility model relates to the technical field of flue gas purification, in particular to an integrated desulfurization, denitrification and dust removal device which is easy to clean. Background Art
[0002] Flue gas desulfurization and denitrification technology is a boiler flue gas purification technology used in the chemical industry that produces a lot of nitrogen oxides and sulfur oxides. Nitrogen oxides and sulfur oxides are one of the main sources of air pollution. Therefore, the application of this technology has many benefits for environmental air purification. Known flue gas desulfurization and denitrification technologies include PAFP, ACFP, pyrolusite method, electron beam ammonia method, pulse corona method, gypsum wet method, catalytic oxidation method, microbial degradation method and other technologies. In order to prevent acid rain and other harmful substances from seriously polluting the atmosphere, the generated flue gas needs to be treated with desulfurization, denitrification and dust removal processes.
[0003] In the prior art, there are the following problems:
[0004] At present, when the integrated desulfurization, denitrification and dust removal device desulfurizes and denitrates the flue gas, the flue gas is generally mixed with the desulfurization solution and the denitrification solution for reaction before desulfurization and denitrification. When the desulfurization solution and the denitrification solution reach saturation after a period of use, the staff needs to replace them. The replacement efficiency of the desulfurization solution and the denitrification solution is low, and the desulfurization solution and the denitrification solution reach saturation after a period of use, which is easy to discharge the flue gas that is not completely desulfurized and denitrified directly to the outside, which is easy to cause environmental pollution. When the dust in the flue gas is filtered, the dust in the flue gas is easy to clog the filter structure and affect the flue gas purification rate. For this reason, we propose an easy-to-clean integrated desulfurization, denitrification and dust removal device to solve the existing problems. Utility Model Content
[0005] The purpose of the utility model is to provide an integrated desulfurization, denitrification and dust removal device which is easy to clean, so as to solve the problems raised in the above-mentioned background technology.
[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an easy-to-clean integrated desulfurization, denitrification and dust removal device, comprising a shell, a rotating shaft is installed inside the shell, one end of the rotating shaft is installed in a bearing on an outer wall of one side of the shell, the other end of the rotating shaft passes through the bearing on the outer wall of the other side of the shell and extends to the outside and is connected to a reduction motor through a coupling, a cam is installed on the outer wall of the rotating shaft, a connecting plate is provided at the bottom of the cam, and the upper surface of the connecting plate is in contact with the outer wall of the cam, the outer walls on both sides of the connecting plate are connected to the first connecting rod through a second connecting rod, the first connecting rod is installed on the top of a second U-shaped card plate, and a plate filter is installed between two adjacent second U-shaped card plates. A second protrusion is installed on the outer wall of one side, and the other end of the second protrusion is installed in the strip slot hole. A through hole is opened on the surface of the second protrusion, and a guide column is installed in the through hole. The two ends of the guide column are respectively installed on the two ends of the hole wall of the strip slot hole, and a spring is sleeved on the outer side of the outer wall of the guide column, and the spring is located between the surface of the second protrusion and the hole wall of the strip slot hole. A plate-type honeycomb denitrification molecular sieve is arranged above the cam, and a honeycomb desulfurization molecular sieve is arranged above the plate-type honeycomb denitrification molecular sieve. An exhaust pipe is arranged at the top center of the shell, and a VOCS detection sensor and a gas flow rate detection sensor are arranged on the inner wall of the exhaust pipe, and the VOCS detection sensor is located above the gas flow rate detection sensor.
[0007] Through the coordinated arrangement of a series of structures such as VOCS detection sensors, plate-type honeycomb denitrification molecular sieves, and plate-type honeycomb desulfurization molecular sieves, the plate-type honeycomb denitrification molecular sieves and the plate-type honeycomb desulfurization molecular sieves can desulfurize and denitrate the flue gas.

Compared with the prior art, the utility model improves the staff's efficiency in disassembling and replacing the plate-type honeycomb denitrification molecular sieves or the plate-type honeycomb desulfurization molecular sieves. The VOCS detection sensor detects in real time whether the purified flue gas discharged from the exhaust pipe meets the standards and displays it on the display screen on the PLC controller, which is convenient for the staff to view and avoids a large amount of unmet needs. To prevent the flue gas that does not meet the emission standards from being discharged to the outside and causing environmental pollution, a series of structures such as a reduction motor, a rotating shaft, a cam, a connecting plate, a spring, and a plate filter are arranged in coordination. When the flue gas is transported to the inside of the shell and filtered through the plate filter, some dust in the flue gas will be adsorbed on the plate filter.

When the gas flow rate detected by the gas flow rate detection sensor is lower than the preset gas flow rate, the PLC controller controls the reduction motor to start, and the reduction motor drives the cam to rotate. The rotation of the cam can cause reciprocating extrusion on the connecting plate. After the reciprocating extrusion, the connecting plate will cause the plate filter to vibrate up and down. The up and down vibration of the plate filter can vibrate the dust adsorbed on the plate filter, thereby avoiding the situation where dust blocks the plate filter.

[0015] Compared with the prior art, the beneficial effects of the utility model are:
[0016] 1. The utility model adopts the coordinated arrangement of a series of structures such as VOCS detection sensor, plate-type honeycomb denitration molecular sieve, plate-type honeycomb desulfurization molecular sieve, etc. The plate-type honeycomb denitration molecular sieve and the plate-type honeycomb desulfurization molecular sieve can desulfurize and denitrate the flue gas. When the staff needs to disassemble and replace the plate-type honeycomb denitration molecular sieve and the plate-type honeycomb desulfurization molecular sieve, the staff can directly draw out the plate-type honeycomb denitration molecular sieve or the plate-type honeycomb desulfurization molecular sieve after opening the sealed door to disassemble and assemble it.
