according to the online air quality analyzer based on the Internet of things, through the design of the cooling component 34, on one hand, moisture in air entering the interior of the drying box 33 can be cooled and dried, then the air enters the temporary storage tank 38 for temporary storage or is input into the air analyzer 4, specifically, the height of the air guide port 331 on the side wall of the drying box 33 is lower than the installation height of the cooling component 34 so as to facilitate the air flow to flow upwards through the cooling component 34, meanwhile, a negative pressure pumping device is arranged in the temporary storage tank 38 to guide the air flow to flow upwards into the temporary storage tank 38, and after the air flow contacts with the surfaces of the cooling plates 342, the moisture therein is condensed into water drops; on the other hand, the protrusion 343 provided on the cooling plate 342 can balance the temperature difference of the air between two adjacent cooling plates 342, specifically, compared with the air temperature initially entering from below the cooling assembly 34 being higher at the middle or tail of the cooling plate 342, in the space between the two cooling plates, the hot air needs to be closer to the cooling plate to achieve a good heat dissipation effect, otherwise, the air temperature in the middle of the space between the two cooling plates 342 is higher than the temperature at both sides;
on the other hand, the height of the protruding portion 343 is sequentially reduced along the airflow flowing direction, and the protruding portions 343 on the two adjacent cooling plates 342 are also staggered, so that in the process of ensuring that air flows through the cooling plates 342, the distance between the two adjacent cooling plates 342 is gradually increased along with the reduction of the air temperature, so that the air flow is gradually increased, the problem of reducing the cooling effect or the cooling rate caused when the hot air and the cold air are at the same flow rate is avoided, and the upward flowing airflow and the protruding portion 343 can buffer the downward flow of the condensed water formed on the surface of the cooling plates 342, so that the water drops are prevented from directly falling to the bottom of the drying box 33, and the water drops are prevented from splashing, so that the condensed water is not beneficial to timely discharging.
Referring to fig. 1-2, fig. 17, a gas analyzer 4 has an analyzing box 41, the analyzing box 41 has a square box structure, a main controller 42 is fixedly connected to one side surface of the analyzing box 41, an analyzing tank 43 is fixedly connected to the other side surface of the analyzing box 41, an exhaust port 431 is arranged at the lower end part of the analyzing tank 43, an air inlet port 44 is arranged at the top of the analyzing box 41, a mounting transverse plate 45 is fixedly connected to the bottom of the analyzing box 41, mounting bending plates 46 are fixedly connected to two end parts of the mounting transverse plate 45, a pressure gauge 47 is arranged on the analyzing tank 43, and the mounting bending plates 46 are fixedly connected to a main bearing disc 11 through fixing pieces 112;
according to the online atmospheric quality analyzer based on the Internet of things, through the design of the gas analyzer 4, an air inlet port 44 on the gas analyzer 4 is communicated with a temporary storage tank 38 through an air pipe, specific components in air can be analyzed by each analysis tank 43, main components in the atmosphere are analyzed by each analysis tank 41, analysis results are summarized to a main controller 42 and output to a main console, and meanwhile, the internal air pressure of the analyzer can be monitored through a pressure gauge 47 arranged on the analysis tanks 43.
It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The present embodiments are, therefore, to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
