Detailed Description
Preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only for explaining the technical principle of the present invention, and are not intended to limit the scope of the present invention.
The utility model provides a sampling device for monitoring smoke emission, which comprises a sampling box, a confluence box, a sampling tube and a sampling probe. The bottom of the sampling box is communicated with the top of the confluence box. The top of sampling case is provided with the end cover. The right center of the end cover is provided with a mounting hole, the end cover is also provided with a plurality of smoke inlets, and the smoke inlets surround the mounting hole to form a circle. The smoke inlet is used for connecting different smoke pipelines in the production system, and the generated smoke is discharged into the sampling box.
The sampling tube is "J" type, and outside the vertical upwards stretching out the sampling case of mounting hole was followed to the one end of sampling tube, the other end of sampling tube was located the sampling case, and sampling probe installs the one end that is located the sampling case at the sampling tube. The sampling probe was model number testo 06007610.
A rotary cylinder is arranged in the sampling box and sleeved outside the sampling probe. And a connecting plate is arranged between the rotary cylinder and the sampling tube, and the connecting plate is connected with the rotary cylinder and the sampling tube in a welding manner. The axis direction of the rotary cylinder is consistent with that of the smoke inlet, and the rotary cylinder is attached to the end cover. The rotary cylinder corresponds to the smoke inlet, and the diameter of the rotary cylinder is larger than that of the smoke inlet.
And a driving device for driving the sampling tube to rotate is arranged outside the sampling box. The driving device comprises a mounting pipe, a mounting seat and a servo motor. The vertical setting of installation pipe, its bottom weld in mounting hole department, and the mount pad is fixed in the top of installation pipe, and servo motor fixes on the mount pad, and servo motor's output shaft is deepened the inside of installation pipe. The end of the sampling tube, which is positioned outside the sampling box, also extends into the mounting tube and is connected with an output shaft of the servo motor.
The servo motor rotates to drive the sampling tube to rotate, and then the rotary cylinder and the sampling probe are driven to rotate. The servo motor can rotate by different angles according to the set PWM signal. In the rotation process of the sampling tube, the rotary cylinder is coaxially opposite to each smoke inlet, so that the smoke discharged from the smoke inlet into the sampling box directly enters the rotary cylinder, and then the parameters of the smoke are directly acquired by the sampling probe. Because the rotatory section of thick bamboo blocks, the flue gas can be continuously blown off downwards from advancing the mouth in addition, so can not receive the influence of other flue gases in the sampling box during the sampling of sampling probe, and then the parameter that acquires every mouth exhaust flue gas that advances that sampling probe can be accurate.
In addition, two sealing bearings are further arranged in the mounting pipe and used for supporting the mounting pipe and preventing the smoke from overflowing. And a diagnostic instrument interface is arranged on the pipe wall of the mounting pipe and is arranged between the two sealing bearings. The diagnostic meter interface is used for mounting the diagnostic meter. The model number of the diagnostic meter is testo 310.
The sampling probe can not seal the sampling tube, and the smoke discharged into the rotary cylinder is discharged downwards, and a part of the smoke enters the sampling tube. Three smoke outlet holes are formed in the part, in the mounting pipe, of the sampling pipe, and the smoke outlet holes are located between the two sealing bearings. The smoke entering the sampling pipe is discharged into the mounting pipe from the smoke outlet hole and is captured by the diagnostic instrument. Through sampling probe and diagnostic instrument, realize the independent measurement to flue gas in certain pipeline.
And a fixed swirl blade is arranged in the sampling box and is used for uniformly mixing the flue gas entering the sampling box from the plurality of smoke inlets and then flowing into the confluence box. The smoke blown into the confluence box is formed by mixing the smoke exhausted from the smoke inlet. One end of the sampling box connected with the confluence box is in a closing-up arrangement, and the sampling box has the advantages of 1 and convenience for installing the swirl vanes; 2. the size of the swirl vane can be reduced, and the cost is reduced; 3. the small size space is beneficial to the swirl blades to stir and fully mix the flue gas; 4. the tapered mouth will accelerate the flow of flue gas through, better facilitating mixing.
The bottom of collection flow box sets up the outlet flue for discharge flue gas. And a smoke online instrument interface is also arranged on the combiner box and used for installing a smoke online instrument to carry out numerical monitoring on the mixed smoke. The model of the smoke online instrument is CEMS-2000. And the two opposite ends of the confluence box are respectively provided with an emission end of an ammonia gas online analyzer and a reflection end of the ammonia gas online analyzer.
In general, the sampling device for monitoring smoke emission disclosed by the utility model can monitor smoke in a certain single pipeline so as to obtain the actual condition of pollutant concentration at each point in a pollution discharge flue; and the mixed flue gas discharged by a plurality of pipelines can be monitored so as to measure the mean value data of pollutants in the flue gas. The utility model realizes the independent monitoring of each area of the flue by using a scheme with lower cost, does not need to use a plurality of sets of equipment, can independently measure the data of each area while measuring the mean value data of the flue gas, and greatly shortens the independent measurement time.
