Contact: 13259782015 Zhang Lei 4.2.1 4.2.1.1 probe and processing unit dedicated electric heating sampling probe is mounted on the flue, including sampling and purging unit consists of the following components: 1) the sampling probe: Φ50mm stainless steel, stretch about one meter into the flue at about the position, the sample gas through the tube into the sampler. 2) Ceramic Filter: filtering accuracy of 10um, the vast majority of the flue dust filter is blocked outside. 3) electric heating tube: the sample cell in order to prevent condensation in the device and the establishment of the heating temperature can be controlled at about 140 ℃. 4) flange butt: sampling unit flange and nozzle flanges relative access technology to complete the installation of the sampling unit. 5) metal mounting bracket shell: sampling unit each member has a shield connected together to achieve the purpose of rain and dust. 6) cleaning system: In order to prevent the accumulation of dust around the filter, causing blockage affects the sample gas flow, the device must purge timing, in order to prevent anti-blowing pressure below standard, this device is designed with anti-blowing gas tank, and cleaning cycles depending on the circumstances at the scene, set or modified through the touch screen. 4.2.1.2 probe technology parameter 1) Heating temperature: 120 ~ 160 ℃ 2) Power: AC220V ± 10% 50Hz 3) Power: 150W 4) Working temperature: -20 ~ 45 ℃ 5) dust filtration capacity: 200g / nm3 4.2 .1.3 special electric heating sampling tube heat pipe is connected to the probe and the sample pretreatment system wiring, the use of electric heating in the form, in the middle like the trachea using F6 resistant PTFE hose, sample temperature control at 120 to 160 ℃, so that the water content in the flue gas in the presence of the state in the form of steam, is mixed with the sulfur dioxide to prevent condensation of acid generated by the alarm device. Contact: 13259782015 Zhang Lei 4.2.1.4 sampling tubes technical parameters 1) Heating temperature: 120 ~ 160 ℃ 2) Power: AC220V ± 10% 50Hz 3) Power: 40W / m 4) Weight: 1.5Kg / m 4.2.2 Pretreatment unit pretreatment system to ensure that within the shortest possible time lag, select a representative sample gas, sample gas state, such as temperature, pressure, flow rate, moisture content, the amount of dust, etc., cleanliness analytical instruments operating conditions must be met. Mainly to complete the following tasks. 1) sample extraction: The flue gas sampling pump extraction, providing analytical instruments to measure SO2, NOX, O2 content. 2) In addition to the condensed water: dual compressor chiller two desiccant, peristaltic pump automatic drainage, and the use of membrane dehumidifier to remove moisture in the sample gas. 3) precision filter: Dust further precision to ensure the accuracy of the overall filter 0.2um below. 4) Scaling: timing instrument zero and span calibration. 5) flow regulation: to ensure that the flow injection analysis instruments within 0.5 ~ 0.7L / min. Processing unit comprising: a compressor condenser, antiseptic vacuum sampling pump, mist filter, precision, central cleaning unit, etc., to complete the sample gas purification, dust, dampness, its filtering accuracy 0.1um, fully meet the analytical instruments requirements clean, constant, constant and stable sample gas calibration gas, continuous feeding of the instruments, thus ensuring the accuracy and reliability of the analyzer. First, the sample gas entering the enclosure through an electric valve, electric valve is normally open state, when the purge, the electric valve Close, prevent anti-blowing into the cabinet, played the role of protecting the pretreatment system. Sample gas enters the compressor a condenser to remove moisture, condensate build-up at the bottom of the condenser through a drain automatically excluded peristaltic pump. Then the sample gas through a filter shaker, and then after a two one-way solenoid valve, automatic zero calibration clean air through the valve, the sampling pump out of the analyzer zero point calibration, then the gas into two coolers Further desiccant, gas dehumidified injected standard gas range instrument by sampling pump and a manual three-way valve calibration, finally do further drying the sample gas into the analyzer. Condenser fault signal is generated when the sampling pump stops working, troubleshooting sampling pump starts automatically. After measuring the exhaust gas discharged outdoors condensate produced is stored in the tank corrosion, automatically excluded from automatic trap. If a fault or when maintenance is required corresponding signal sent to the control room, the operator will discover. 4.3 Analysis of the cabinet 1) Frame size: 2000mm (H) * 600mm (W) * 600mm (D) 2) Degree of protection: IP54 3) Cabinet material: cold-rolled carbon steel plate 4) In order to facilitate the lifting of the cabinet, with top cabinet The lifting lugs. 4.4 System Specifications 1) Adaptation: online analysis of flue gas composition, dust, flow, temperature parameters and continuous monitoring. 2) measures to reduce the impact of a shock event, use the following two measures to minimize the impact to make a shock event: to ensure that the system is grounded, the signal to increase signal isolation, surge suppression devices installed in the import and export cables for Surge suppression design. 3) equipment grounding maximum resistance: an equipment grounding resistance of less than 4 ohms maximum. 4) protection method flue devices: no flue hood components that can withstand high temperatures and insulation; and all arranged in outdoor or harsh environmental conditions where the control box, cabinet used in all carbon steel materials, degree of protection is not less than IP65 5) to prevent clogging of the line probe measures: a sampling probe with a temperature control device, temperature control probe at 120 ~ 160 ℃, water has been in the vapor state, will not liquefy, the probe filter accuracy 5um, can The vast majority of dust filtered out, while the probe on a regular cleaning function, can be attached to the probe filter core flue dust blown back. Therefore, the sampling probe and the pipeline will not be clogging. 6) the calibration gas storage methods and requirements: Standard gas stored in controlled environmental conditions between the instruments, standard gas cylinders made of wood or steel produced bracket to the wall 1 to 2 meters away from the main cabinet, bottom placed on the ground, determine the standard cylinder fixed and reliable, and easy disassembly, standard cylinders through valves, corrosion-resistant pipe is connected to the control unit or gas samples directly to the analyzer's standard port, check the tightness of standard cylinders air inlet and outlet valve with a pressure gauge to indicate the pressure and the remaining capacity. Environmental requirements: temperature 5 ~ 45 ℃, Relative Humidity: 0 to 75%, without a strong heat and vibration source nearby. Contact: 13259782015 Zhang Lei
