Ceramic cems flue gas online monitoring system Environmental Protection Bureau requires installation of equipment

I. Product application range The ceramic smoke online monitoring system is suitable for building ceramic manufacturing enterprises, independent dry blank manufacturing or firing, and independent baking process. Real-time monitoring of particulate matter concentration, sulfur dioxide (SO2) concentration, nitrogen oxide (NOX) concentration, oxygen (O2) content, flue gas temperature, flue gas pressure, flue gas flow rate, humidity, and carbon monoxide ( CO), carbon dioxide (CO2), hydrogen chloride (HCL), hydrogen fluoride (HF), ammonia (NH3), hydrocarbon (CHX) and other parameters. It can also be connected to the computer of the superior environmental protection department through the network, and the environmental protection department can conveniently and quickly call the monitoring data.

Product advantages
1. The pre-processing system adopts a front door cradle design. The heating temperature of the probe, the sampling tube and the backflush time are directly set on the man-machine dialogue screen, and can be set, fault alarm, PLC status and other information. Convenient for later maintenance.
2. The pre-processing system is equipped with a sample gas humidity alarm device. The humidity can interlock the entire system to protect the analyzer from water pollution.
3. The analysis flowmeter adopts Dwyer imported from the United States to ensure that the sample gas flows into the gas analyzer steadily and is not affected by the fluctuation of gas flow, thereby making the measurement data more accurate.
4. The pre-processing system is open circuit, the terminal is ABB, the relay and temperature controller are Omron products, and the 24v power supply, temperature control module, PLC and I / O expansion module are Siemens products.
5.The flue gas analyzer uses imported spectrometers and key components. The range is dual range. The range can be manually / automatically switched to ensure the accuracy at different levels. The use is more stable and the data is more accurate.
6. The pre-processing system uses an electric ball valve to achieve the zero-range automatic calibration function.
7. Support remote configuration and remote diagnosis analyzer via GPRS.
8, the analysis system contains automatic standard effects, one-click leak detection, one-click maintenance and other functions.
9. Provides PC-side and **-side APP, with functions such as display monitoring, data processing, report management, remote communication, remote monitoring, and abnormal alarm.

3. Sewage production and discharge links (1) PM: mainly from crushers, polishing machines, firing kiln, drying kiln (room), spray drying tower, hot air stove, cutting machine, edger, glaze line machine and other ventilation production equipment, etc. .
(2) SO2, NOx: mainly from firing kiln, drying kiln (room), spray drying tower, hot air furnace, etc.

IV. Verification methods (1) Electricity analysis: Obtain the power consumption of the company from the grid company, analyze the changes in electricity during the historical warning period, and compare the changes in electricity consumption during normal production and the period of emission reduction measures. Business.
(2) On-site inspection: On-site inspection is to check whether the production facilities of ceramic firing kiln, roasting kiln, etc. have been stopped.
(3) Checking the ledger: Check the historical data such as production records, production line operation records to confirm the production suspension and limit, read the natural gas usage records to confirm the natural gas usage, and check whether the online monitoring data meets the standard emissions.
(4) Transportation inspection: Obtain video monitoring records of the factory gates, compare the frequency of transportation of heavy-duty trucks in the factory area before and after the warning, and check whether they meet the requirements; spot-check the running vehicles to check whether the emission standards meet the requirements.

V. Emission reduction measures (1) A-level enterprises:
It is encouraged to take measures to reduce emissions in accordance with the actual situation.
(2) Class B enterprises:
Orange and above warning period: the roasting process is suspended for more than 50% (inclusive), based on the production line; transportation is prohibited.
(3) C-level enterprises:
Yellow and above warning period: production stop and transportation prohibited.
(4) Wei Tao and daily ceramics:
Red warning period: stop production and prohibit transportation.
(5) Remarks:
For processes that are difficult to stop in a short period of time, such as roasting, it is recommended to adjust the production plan in advance during autumn and winter when heavy pollution is frequent, to ensure that the enterprise's roasting process can effectively implement emergency emission reduction measures. Cities with conditions can take a regionally coordinated approach in combination with actual conditions to implement production cuts and emission reductions in turn; during non-autumn and winter periods, they can use furnace shutdowns and kiln reductions to reduce pollutant emissions.
Sanitary ceramics and daily-use ceramics are not involved in performance classification.
