Description
Technical Field
The utility model relates to a pollution sources detects technical field, specifically says and involves a smoke and dust flue gas detector.
Background
At present, when the smoke detector detects working conditions and smoke particulate matter concentration, a pitot tube needs to be inserted into a flue, pressure in the flue passes through the pitot tube and is transmitted to a pressure sensor inside the measuring instrument, so that the pressure in the flue is read, and the pressure value participates in working condition measurement and smoke particulate matter concentration calculation.
When the moisture content concentration in the flue is high, part of water vapor enters the pitot tube, and the water vapor forms condensed water in a gas path from the pitot tube to the pressure sensor due to the temperature difference along with the increase of the detection time. In order to eliminate the influence of condensed water, a micro filter element is arranged at the front end of the pressure sensor of part of the detector, the filter element is made of filter cotton, once the condensed water is met, the pressure cannot be transmitted to the pressure sensor, and finally the measurement fails; on the other hand, when the amount of condensed water is large, the condensed water can pass through the filter element and reach the pressure sensor, and finally the sensor is damaged; on the other hand, the filter element can not be freely disassembled and replaced inside the instrument, and can only be sent back to a manufacturer for maintenance or can be continuously used after long-term waiting for the water in the filter element to evaporate. The mode for protecting the sensor has high maintenance and time cost, and greatly reduces the detection efficiency.

Detailed Description
In order to make the above objects, features and advantages of the present invention more clearly understood, the present invention will be described in further detail with reference to the accompanying drawings and examples.
In the first embodiment, referring to fig. 1, the first embodiment provides a condensing device, which includes an upper ventilation shell 3-1, a lower ventilation shell 3-2, an air inlet nozzle 3-3, and an air outlet nozzle 3-4, wherein the upper ventilation shell 3-1 and the lower ventilation shell 3-2 are connected together to form a water storage cavity, the top surface of the upper ventilation shell 3-1 is provided with the air inlet nozzle 3-3 and the air outlet nozzle 3-4, and when considering that the condensing device has a scene of rotating 90 degrees and rotating 180 degrees or being completely inverted in the use process, the air inlet nozzle 3-3 and the air outlet nozzle 3-4 are designed to protrude from the top surface of the upper ventilation shell 3-1 in the water storage cavity, and the protruding air inlet and outlet nozzles can prevent condensed water from flowing backwards into an air inlet channel.
In order to conveniently detach the ventilation upper shell 3-1 and the ventilation lower shell 3-2, the ventilation lower shell 3-2 is designed to be in a knob type, and the knob is in threaded connection with the ventilation upper shell and is sealed by a sealing ring 3-6. Of course, the connection mode between the lower ventilation shell 3-2 and the upper ventilation shell 3-1 is not limited to threaded connection, and the connection can be realized by adopting structures such as buckles or silica gel plugs and the like.
In order to improve the condensation effect, the height of the air outlet nozzle 3-4 in the water storage cavity is higher than that of the air inlet nozzle 3-3. The inner diameter of the air outlet nozzle 3-4 is smaller than that of the air inlet nozzle 3-3, so that the retention time of water vapor in the condensing device can be prolonged, namely the cooling and condensing time of the water vapor is prolonged. In addition, a condensation wall 3-5 is arranged between the air inlet nozzle 3-3 and the air outlet nozzle 3-4 on the top surface of the air exchange upper shell 3-1 in the water storage cavity, and the height of the condensation wall 3-5 is higher than that of the air outlet nozzle 3-4. Thus, after entering the condensing device, the airflow collides with the condensing wall 3-5 to form partial condensed water, and then collides with the air outlet nozzle 3-4 again to be condensed again, and finally forms the anhydrous airflow.
In order to conveniently observe the volume of the condensed water and drain water in time, the lower ventilation shell 3-2 is made of transparent plastic.
In the second embodiment, referring to fig. 2, the present embodiment provides a smoke and fume detector 2 with a condensing device 3 in the first embodiment, which includes a sampling pipeline 2-3, a filter element 2-1, and a pressure sensor 2-2. The middle section of the sampling pipeline is divided into a first branch and a second branch, the air inlet nozzle 3-3 is connected with the first branch, and the air outlet nozzle 3-4 is connected with the second branch. For convenient installation, the air inlet nozzle 3-3 and the air outlet nozzle 3-4 protrude out of the top surface of the air upper shell in the water storage cavity.
The utility model discloses increase a condensing equipment before the filter core, the device exposes the instrument, because external environment temperature is less than flue 1 internal temperature, so aqueous vapor forms the comdenstion water in the device, suction nozzle among the condensing equipment, play gas nozzle can prolong aqueous vapor detention time, and the condensation wall makes the aqueous vapor strike here, further promotes condensation effect, ensures that aqueous vapor can not enter into the condensation of the filter core department of rear end. The condensing device exposes the instrument, so that the condensed water capacity can be observed in real time, the condensed water can be poured conveniently, and the adverse effect of the condensed water on the pressure sensor is eliminated.
The utility model discloses condensing equipment is not limited to and installs on above-mentioned smoke and dust flue gas detector, still can install on pollution sources check out test set such as smoke and dust flue gas sampling pipe.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention in other forms, and any person skilled in the art may use the above-mentioned technical contents to change or modify the equivalent embodiment into equivalent changes and apply to other fields, but any simple modification, equivalent change and modification made to the above embodiments according to the technical matters of the present invention will still fall within the protection scope of the technical solution of the present invention.
