Portable denitration catalyst honeycomb hole dredge

Abstract

A portable denitration catalyst honeycomb hole dredge is characterized by comprising a housing, a mounting plate and dredging needles; the dredging needles are arranged corresponding to the position of honeycomb holes, the mounting plate is provided with mounting holes corresponding to the dredging needles, the dredging needles penetrate into the corresponding mounting holes, the tail end of each dredging needle is in transmission connection with a rotation output shaft of a motor, the motor is arranged and located in relative to the mounting plate, the mounting plate is slidably arranged in relative to a housing by a liner driving mechanism along the axial direction of the dredging needles, positioning plates are arranged in intervals along the axial direction of the dredging needles, the positioning plates are provided with guiding holes corresponding to the dredging needles, the dredging needles penetrate into the corresponding guiding holes, and springs are arranged between adjacent positioning plates. The portable denitration catalyst honeycomb hole dredge can simultaneously dredge multiple honeycomb holes, dredge efficiency is greatly improved, and manpower is saved.

Description

technical field [0001] The invention relates to the field of flue gas purification, in particular to a dredger for flue gas denitration and nitrogen oxide removal catalyst honeycomb holes in the fields of thermal power plants, coal-fired power plants, gas turbine units, garbage incineration, steel, petrochemical, and internal combustion units. Background technique [0002] my country's energy structure is dominated by coal, and coal consumption will continue to grow. According to statistics, thermal power installed capacity accounts for more than 74% of my country's installed power generation capacity. For a long time to come, nitrogen oxide pollution caused by coal burning will be another important environmental problem after sulfur dioxide pollution. [0003] At present, there are mainly two types of NOx control technologies: one is the combustion process control technology, which is characterized by controlling the generation of NOx in the combustion process, including th...

AI Technical Summary

Problems solved by technology

Certain pollutants in the complex flue gas are likely to poison the catalyst, and dust particles cover the surface of the catalyst to reduce its activity. At the same time, SO2 in the flue gas reacts with some unreacted HN3 in the flue gas to form NH4HSO4 and (NH4)2SO4, resulting in Corrosion and plugging of honeycomb holes, resulting in a reduction in the catalyst reaction area, a decrease in the removal rate of nitrogen oxides, and an increase in system resistance

At present, iron wires are usually used to dredge the clogged honeycomb holes manually. The dredging efficiency is extremely low and the labor intensity is extremely high.
