Embodiment Construction
[0062] After the applicant's research and analysis, the reason for this problem (the traditional treatment system is likely to cause huge energy waste of electric energy and natural gas during intermittent work) is that the existing structure is characterized by large volume of treatment facilities and high operating cost, which is suitable for continuous exhaust gas. Emission and concentration balance conditions, but for intermittent production process, without adjustment of equipment structure and operating parameters, it will cause huge energy waste of electric energy and natural gas. The traditional treatment system is basically designed as a set of adsorption mechanisms connected to the regenerative furnace. Therefore, The adsorption mechanism and the regenerative furnace are required to carry out real-time combustion and heating, and even when the exhaust gas is small, the entire working unit needs to operate to complete the treatment of the exhaust gas. For the intermitte...

The invention discloses a waste gas treatment system for coating steel structure parts, comprising: a waste gas inlet branch, a rotary adsorption and desorption device communicated with the waste gas inlet branch, and a filter branch communicated with the rotary adsorption and desorption device; The desorption branch communicated with the filtering branch, the processing branch communicated with the rotary adsorption and desorption device, and the combustion-supporting branch communicated with the processing branch; the filtering branch and the processing branch are connected chimney. By designing the rotary adsorption and desorption device through the double-layer filtration adsorption form of the zeolite molecular sieve adsorbent and the corrugated zeolite molecular sieve adsorbent, the rotary adsorption and desorption device can be maintained offline for a certain period of time. The thermal combustion furnace decomposes four branches, and then controls the coordinated start and stop of four sets of rotary adsorption and desorption devices to reduce the electricity and natural gas consumption of waste gas treatment facilities and equipment in the intermittent production process.
Description
technical field [0001] The invention relates to a waste gas treatment system, in particular to a waste gas treatment system for coating steel structure parts. Background technique [0002] The "Interim Measures for the Calculation of Volatile Organic Compound Emissions in Key Industries in Jiangsu Province" regulates and guides the calculation of volatile organic compound (VOCs) emissions in key industries in the province, finds out the VOCs emission base, provides basic data for pollution prevention and control, and realizes the refinement of VOCs. The management has formulated specific rules to urge enterprises to actively carry out source governance, process control and end governance. [0003] The existing structure is characterized by large volume of treatment facilities and high operating cost, which is suitable for continuous exhaust gas discharge and balanced concentration conditions. However, for intermittent production processes, without adjustment of equipment str...
