Description
Technical Field
The utility model belongs to the technical field of gaseous sampling test, specific theory relates to a sulfuric acid mist monitoring sampling device.
Background
In the existing sulfuric acid industrial manufacturing process, in order to monitor the gas components and the gas phase acid-carrying condition in the dry absorption tower, the dry absorption tower is only provided with a sampling short connecting pipe on the tower wall during design, a common sampling glass pipe is about 2 meters long, gas samples at different positions in the tower are difficult to collect, a sampling point is unique, the gas components in the tower cannot be truly reflected, the conditions of uniform distribution of absorption liquid in the tower, gas absorption efficiency and the like are difficult to judge, and the method has limitation on the condition that large-scale equipment cannot well reflect different position working conditions in the equipment during monitoring.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the problem in the prior art, design a sulfuric acid mist monitoring sampling device, accomplish the multiple spot sample, medium composition in the true reaction equipment, the sampling is convenient.
In order to achieve the purpose, the utility model is realized according to the following technical scheme:
the utility model provides a sulfuric acid mist monitoring and sampling device, which comprises a sampling tube 1, a gas-leading hole 2 and a gas outlet 3; sampling tube 1 be located the tower divide between acid ware 4 and the defroster 5, the vertically is installed on the tower wall, 1 one end of sampling tube is equipped with gas outlet 3, the other end is the blind end, gas outlet 3 passes the tower wall and arranges in outside the absorption tower, three bleed hole 2 is along the even distribution of 1 axial of sampling tube on sampling tube 1, 2 diameters of bleed hole are halved from 1 blind ends of sampling tube to gas outlet 3 gradually, first bleed hole 2 is located absorption tower central point and puts, the diameter equals 1 internal diameters of sampling tube.
Preferably, the sampling tube 1 is a stainless steel tube, and the length of the sampling tube is greater than the radius of the absorption tower.
Preferably, the sampling tube 1 is connected with the tower body by adopting an embedded flange, an acid-resistant polytetrafluoroethylene plate is assembled to be used as a sealing gasket, and the air introducing hole 2 is over against the ascending direction of the air flow in the tower.
The utility model has the advantages that: single-point sampling is replaced by multi-point sampling, the matching degree of the sample and the actual sample is high, and the medium components in the equipment can be truly reflected; the sampling device is vertical to the direction of the airflow, the tail end of the pipe is smoothly sealed and welded, and the sampling port is opposite to the direction of the airflow, so that the sampling is facilitated; the sample connection is located the pipeline lower limb, is convenient for avoid "liquid collecting" problem and original sampling tube jam trouble and arouses the analysis result skew.

In the figure, 1-a sampling tube, 2-an air introducing hole, 3-an air outlet, 4-an acid distributor and 5-a demister.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the following will explain in detail a preferred embodiment of the present invention with reference to the accompanying drawings to facilitate understanding of the skilled person.
As shown in fig. 1-2, the sulfuric acid mist monitoring and sampling device comprises a sampling pipe 1, a gas introducing hole 2 and an air outlet 3; sampling tube 1 be located between acid distributor 4 and the defroster 5 in the tower, adopt embedded flange joint vertically to install on the wall of the tower, assemble acidproof polytetrafluoroethylene board as sealed the pad, easy access and maintenance, sampling tube 1 chooses for use DN 25's 316L stainless steel pipe, length is greater than the absorption tower radius, one end is equipped with gas outlet 3, the other end is the blind end, gas outlet 3 passes the wall of the tower and arranges in outside the absorption tower, three bleed hole 2 is along the even distribution of sampling tube axial on sampling tube 1, the diameter is halved gradually from sampling tube 1 blind end to gas outlet 3, first bleed hole 2 is located the absorption tower central point, the diameter equals sampling tube 1 internal diameter, the bleed hole is to keeping away from gas outlet end bleed hole aperture crescent, with balanced three bleed hole air intake resistance, make each bleed hole air input equal. By adopting multi-point sampling, the matching degree of the sample and the actual sample is high, the medium composition in the equipment can be truly reflected, the air guide holes 2 are over against the ascending direction of the air flow in the tower, the sampling is facilitated, and the problem of liquid collection and the deviation of the analysis result caused by the blockage fault of the original sampling pipe can be avoided.
Finally, it is noted that the above-mentioned preferred embodiments illustrate rather than limit the invention, and that, although the invention has been described in detail with reference to the above-mentioned preferred embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the scope of the invention as defined by the appended claims.
