Gas samples with high moisture sample pretreatment system design

Really deal with special difficulties, so this option is feasible. 2.2 The selection of the original sampling point may be for the convenience of the original sample tap in the final after a steam jet pump. However, before the emission Yan, close to the platform less than half a meter long section of the level of Pa 00rrm pipe. Sampling tube for the worship 0H Ⅱ n the ordinary steel pipe,[link widoczny dla zalogowanych], welded pipe at the top of the craft. The length of the horizontal pipe and the valve short-barrier effect, so there might be water (that is, out of water with the gas sample into a great possibility that pre-treatment system), automatic drainage because of insufficient capacity of the original, so buried water into the seeds of the instrument. 2.3 The new sampling points chosen to select a new sampling point after the discharge valve vertical pipe section, where about 1 meter away from the platform. The level of process piping from about l meter. Ruled out the gas sample with a clear water possible. Therefore greatly reducing the burden of pre-treatment system. 3, the design of the sampling probe with a buffer of high moisture gas samples for the sampling, with no water in the sampling of the instruments at the 1999 3 or less with the water still is very important in order to achieve this purpose, a specially designed low-cost sampling probe with a special buffer, as shown in Figure l. Figure 1 Schematic sampling probe with a buffer gas sample to sample and make the gas-water separator for automatic drainage, the design has taken the following measures: (1) gas pipeline by ~ lOmm like stainless steel, one-way downward installation . (2) two-stage gas-water separation devices, the first stage set into the instrument before the complete system, outside the room. After a gas-water separation, with the peristaltic pump water directly; the second level on the meter room, the same peristaltic pump water directly. (3) using the water level in the second interlock alarm protect the gas-water separator designed a pair of cable, when the anomalies so that the water level up to the electrode to drown it, in addition to normal drainage outside. Electrode-related delay time relay began. If the production. Relay delay period, the drainage discharge abnormally,[link widoczny dla zalogowanych], that is, the electrode can not set the time delay from the flood, then cut off the gas sampling, sample pre-treatment system so that the suction pump to stop working, and alarm operation workers to take urgent measures. Risk of exclusion such as operator, and then return to work. 4 Practical application of process analysis of Chongqing Special Steel Plant in the use of r or more sets of system corrective measures, in the production of satisfactory results achieved with the gas sample into the sample pretreatment significantly reduced the water system,[link widoczny dla zalogowanych], automatic drainage capacity enhancement drainage flow,[link widoczny dla zalogowanych], Shaanxi speed. Additional drainage interlocking automatic alarm device. Reliable, to improve the security of the system operation.
