Description

Start Kit of an air analyzer and operating method Thereof

The present invention relates to an atmospheric analysis apparatus, and more particularly, to a start kit of an atmospheric analysis apparatus and a method of operation thereof, which enable the analysis performance to be quickly exhibited when the atmospheric analysis apparatus is started.

While the rapid development of the modern industrial society has helped to improve the quality of life of mankind, it has caused various environmental problems due to reckless damage to nature and development. In particular, due to the increase in energy consumption due to the rapid industrial development, the emission of air pollutants has increased rapidly, and the resulting pollution problem is facing a serious situation. In order to prevent this, it is essential to understand the type and concentration of each component by monitoring and analyzing gas or air in the atmosphere discharged from various emission sources such as factories or automobile exhaust pipes.

5 is a schematic configuration diagram of a conventional atmospheric analysis apparatus 10. As shown in FIG. 5, the atmospheric analysis device 10, also known as the shelter, inhales air in the atmosphere through the inlet 20, and then removes moisture from the dissolver 30, and then through the air analyzer 50. Measure the concentration of each component (eg, carbon monoxide, carbon dioxide, NOx, sulfide, benzene (B), toluene (T), ethylbenzene (E), xylene (X), fine dust, etc.).

On the other hand, the dissolver 30 is installed on the inlet pipe 25 to remove moisture contained in the incoming air sample by frost. If there is no dissolver 30, an air sample containing moisture is introduced into the air analyzer 50 as it is, thereby preventing accurate concentration analysis. To this end, a Peltier element (not shown) cooled to -30°C is used inside the dissolver 30. Moisture or moisture contained in the air sample is removed as frost while colliding with the Peltier element, and only the dry air sample from which moisture has been removed is transferred to the air analyzer 50.

Therefore, in order to promote the growth of frost, it is preferable that a certain amount of frost is present on the surface of the Peltier element. This is because moisture is easily removed by adhering to the surface and the end of the frost and solidifying it.

By the way, when starting the operation of the atmospheric analysis device 10 that was in a stopped state, idle the atmospheric analysis device 10 for a long time (eg, 1 hour or more) until a certain amount of frost is generated in the dissolver 30 ), and the analysis result that was printed at this time could not be used.

If, in the case of turning off the atmospheric analyzer 10 in the evening and starting the operation in the morning, it was necessary to consume about an hour of time every day and power according to idling. In particular, in a dry season such as winter, it was possible to form a small frost on the surface of the Peltier device only when the idling operation was performed for up to 2 hours.

Therefore, the conventional atmospheric analysis apparatus 10 has a disadvantage in that it is impossible to immediately operate and output results according to environmental changes, and waste time and power through an idling operation of 1 hour or more.

The humidity sensor 130 is installed on the branch pipe 120 to measure the (relative) humidity of the gas passing through the branch pipe 120 and transmits the measurement result to the control unit 200.

The water tank 160 accommodates water 170 therein, and an insulating material 140 is formed around it so as not to freeze in winter.

The heater 180 is provided on the lower surface or the side of the water tank 160 to be heated by electric power, and may convert the water 170 into water vapor.

The refill cap 150 is provided on the upper surface of the water tank 160 and is used to supplement water 170 when there is no water 170 or the water level is low. To this end, the refill cap 150 may be a stopper that the user can open by hand, or may be connected to a water pipe having a solenoid valve to automatically supply water.

The supply pipe 195 is a pipe through which air is supplied, one end is connected to the upper portion of the water tank 160, and the other end is connected to the pump 190.

Example of action

Hereinafter, the operation of the preferred embodiment will be described in detail with reference to the accompanying drawings. 3 is a flowchart illustrating a method of operating a start kit according to an embodiment of the present invention, and FIG. 4 is a detailed flowchart of a step S230 of determining the presence of water in the water tank in FIG. 3.

First, the standby analysis device 10 that has been stopped starts an operation by a user or a timer (S190). At this time, a flow rate of about 5ℓ/min is introduced from the atmosphere.

Then, the controller 200 operates the heater 180 for the first time (about 5 minutes) (S200, S210). Then, the temperature of the water 170 in the water tank 160 rises, and water vapor is generated from the surface of the water to collect on the water tank 160.

Then, the pump 190 operates according to the driving of the motor 192 to supply air (wind) into the water tank 160 through the supply pipe 195. Then, the air is moved to the dissolver 30 through the branch pipe 120 together with the water vapor (S220).

At this time, it is determined whether there is water 170 in the water tank 160 (S230). More specifically, first, the humidity sensor 130 installed in the branch pipe 120 detects the humidity of the air (S232).

Then, the control unit 200 determines whether the humidity is less than or equal to a predetermined humidity (S234). When the heater 180 is sufficiently heated, but the humidity is less than a predetermined humidity (eg, RH 50%), the cause is that there is no water 170. Therefore, the control unit 200 stops the operation of the pump 190 and the heater 180, and notifies the necessity of replenishing water by flashing the LED 210 (S236).

If the detected humidity is greater than the predetermined humidity, the controller 200 determines that moisture is normally supplied and returns to FIG. 3 (S238).

Then, since the air supplied with moisture (moisture) is high in humidity, it quickly transforms into frost on the Peltier surface of the dissolver and begins to grow. As frost grows in the pipeline, the cross-sectional area decreases, and a pressure difference occurs before and after the dissolver 30. The front pressure sensor 32 and the rear pressure sensor 35 are for generating this differential pressure 37.

The control unit 200 determines whether the differential pressure 37 before and after the dissolver 30 in the atmospheric analysis device is equal to or greater than a predetermined pressure (eg, 0.1 psi) (S240).

If the differential pressure is greater than or equal to the predetermined pressure, it is determined that the frost has grown sufficiently, and the operation of the start kit 100 is stopped (S250). Thereafter, even if an air sample is introduced from the atmosphere, moisture can be removed immediately, and concentration analysis becomes possible immediately.

If the differential pressure is less than the predetermined pressure, it is determined that there is no or insignificant frost inside the dissolver 30. Accordingly, the controller 200 operates the pump 190 and the heater 180 for a second time (about 15 minutes) and then stops the operation (S260). The second time (about 15 minutes) may be adjusted in the range of 10 minutes to 20 minutes in consideration of the capacity and seasonal characteristics of the water tank 160 and the heater 180.

The control unit 200 may receive data from the outside through the communication unit 230 or may transmit data of the start kit to the outside. To this end, the communication unit 230 may be a wireless communication network such as wireless Internet, 4G, 5G, Wi-Fi, Zigbee, Bluetooth, low power wide area network (LPWAN), beacon communication module, and the like.
