Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a pretreatment device for a water pretreatment device,

The present invention relates to a pretreatment apparatus for analyzing air pollution, and more particularly, to a pretreatment apparatus for analyzing air pollution, which can effectively remove moisture and particulate matter contained in a combustion gas to be measured, ≪ / RTI >

Due to urbanization, population growth and indiscriminate nature damage, our natural environment is becoming more and more deserted. In particular, it is no exaggeration to say that the environmental pollution that emerged with rapid industrial development is facing not only a limited number of countries, but also all the countries of the world should seriously worry and respond.

To cope with such environmental pollution problems, it can be categorized into the development of technologies for suppressing the emission of pollutants or removing the pollutants that are inevitably discharged.

In order to control the emission of pollutants, emission control standards for each emission source are established and regulated and regulated. In general, monitoring is conducted to confirm the emission amount and emission concentration of pollutants. It is a very important part of the field.

Particularly, devices for monitoring air pollutants derived from combustion of fossil fuels or various manufacturing processes among environmental pollutants use a measurement method based on optical instruments. However, these monitoring devices often have difficulty in determining the exact name or concentration of air pollutants contained in the combustion gas due to moisture or particulate matter contained in the gaseous substance to be measured.

Therefore, in order to grasp the pollutants and their concentrations accurately, it is necessary to remove water or particulate matter which is difficult to measure or analyze beforehand, and to introduce them into the measuring apparatus. In such a case, a filter may be used as the pretreatment method. However, the filter should not be removed due to moisture or particulate matter, as well as water or particulate matter removed from the filter, due to the formation of another filter body. That is, even the gaseous pollutants to be measured can be removed, This may cause difficulties.

In order to solve such a problem, Korean Patent Laid-Open Publication No. 2006-0039465 discloses a pretreatment apparatus for removing moisture. Inside the pretreatment apparatus, a glass tube for cooling and adhering moisture to the inner circumference is provided, and a cotton yarn layer for removing the primary moisture is further formed inside the glass tube. The lower part of the pretreatment apparatus is provided with a peltier trap for performing cooling condensation and thermal desorption so that the pretreatment apparatus equipped with the moisture pretreatment means for analyzing the air pollution heated and driven for removing moisture after the sample collection of the sample collecting unit is completed Lt; / RTI >

Further, in the prior art, a method of removing water and particulate matter from the inflow gas using a cyclone has been proposed (Patent Application No. 10-2015-0062003). That is, the removed moisture and particulate matter are phase-changed into the gaseous state, and then they are dropped and discharged. However, the castle remained frozen without draining, so the worker would turn off the pretreatment device and insert the rod to remove the frozen castle. Because of this, the operator had to be careful about the operation at all times in an uncertain state of the internal state of the cyclone, and had to stop driving occasionally in order to remove the spill.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a pre-treatment apparatus and method for analyzing air pollution measurement according to the present invention will be described in detail with reference to the accompanying drawings.

Example  Configuration

1 is a cross-sectional view of a water pretreatment apparatus for analyzing air pollution measurement that can be applied to the present invention.

First, in the present invention, the term "gelling" means an ice crystal grown by freezing water separated from the inflow gas 200, and may include some particulate matter. Therefore, in the present invention, "to gender" can be used as a concept including pure water and particulate matter. In addition, "gender and particulate matter" means a residual particulate matter that is not included in gender and gender including particulate matter.

As shown in FIG. 1, the gaseous effluent for a water pretreatment apparatus according to an embodiment of the present invention is roughly composed of a first cooling tube 10 and a second cooling tube 70.

The first cooling tube 10 is introduced into the first collecting part 110 of the second cooling tube 70 while the inflow gas 200 enters the first cooling tube 10 at one end with the metal tube installed in the vertical direction.

The first peltier 20 is provided at one side of the first cooling tube 10 to transmit a low temperature (for example, -30 ° C ± 10 ° C) to the inside and generate a high temperature to the outside. The first peltier 20 using the Peltier effect is an apparatus for cooling or heating a specific local region. When the two ends of two different metal wires are joined together and a direct current is passed through the circuit, Heat is generated at the other junctions. If the direction of the current is reversed, endothermic reaction and heat generation occur in opposite directions. This is a kind of heat pumping phenomenon and is the principle of electronic cooling. Therefore, the first peltier 20 using this principle has an advantage that the temperature at a specific position can be accurately maintained at a desired temperature

The first radiator (30) is mounted on the high temperature part of the first peltier (20) where heat is generated, and has a high surface area. The first radiator 30 includes a plurality of radiating fins (or cooling fins), and performs heat exchange with the outside by water-cooling or air-cooling.

The second cooling tube (70) is a metal tube which is installed in a vertical direction in succession to the first cooling tube (10). Accordingly, the upper part of the second cooling tube 70 is connected to the first cooling tube 10, and the lower part is provided with a plurality of ports, and the entrainer 100 is installed therein. The second cooling tube 70 is relatively larger in inner diameter and / or height than the first cooling tube 10 to accommodate the sextant collector 100 therein.

The second peltier 50 is provided at one side or periphery of the second cooling tube 70 to transmit a low temperature (for example, -10 ° C ± 5 ° C) to the inside and generate a high temperature to the outside. This is the same as the first peltier 20 described above in that it uses the Peltier effect. The second radiator (60) is mounted on the high temperature part of the second peltier (50) where the heat is generated, and has a high surface area. The second radiator 60 includes a plurality of radiating fins (or cooling fins), and performs heat exchange with the outside by water-cooling or air-cooling.

The casting collector 100 is composed of an outer tube-shaped outer appearance and an hourglass-shaped inner shape, and is installed vertically in the second cooling tube 70. The upper end of the collecting device 100 is a free end spaced apart from the second cooling tube 70 and the lower end of the collecting device 100 is fixed to the lower surface of the second cooling tube 70. The inside of the collecting device 100 includes a first collecting part 110 at the upper part, a second collecting part 140 at the lower part, and a protruding part 120 provided therebetween.

In order to suppress the heat transfer from the heater 80 installed at the lower part, the collector 100 may be formed of a material having a high heat insulating performance or a material having a low thermal conductivity (e.g., Teflon, ceramics, etc.) or may include these materials.

The first collecting part 110 is a free end whose upper end is opened and is spaced apart from the second cooling tube 70 by a predetermined distance to form a gas passage part 150. The lower end of the first cooling tube 10 extends to the inner intermediate region of the first collecting part 110.

The second collecting part 140 is installed in series below the first collecting part 110. A second discharge port 92 is provided on a side surface of the second collecting part 140, and a first discharge port 91 is provided on a lower surface of the second collecting part 140. The second collecting unit 140 is a space in which the separated gasses 230 are accumulated or the liquid 220 is collected.

The protrusion 120 is located between the first and second collecting parts 110 and 140 and protrudes from the inner surface of the collecting device 100 toward the center. A center hole 130 is formed at the center of the protrusion 120 so that the protrusion 230 can pass through and the upper surface of the protrusion 120 is inclined downward or downward toward the center hole 130, Thereby facilitating the passage of the fluid 230.

The heater (80) is an electrothermal heater installed around the lower part of the second collecting part (140). The periodic heating of the heater 80 melts the sintered body 230 into the liquid 220.

The second cooling tube 70 is provided at its lower end with an analyzer port 75 for delivering the measurement gas 210, a first discharge port 91 for discharging the liquid and a second discharge port (92).

A first valve (90) is provided in the first discharge port (91) to interrupt discharge of the liquid.

The second discharge port 92 is constituted by a second valve 95 which interrupts the discharge of the sludge 230. The vacuum chamber 40 is an empty space for forming a predetermined vacuum pressure, one side connected to the second valve 95, and the other side connected to the vacuum pump 45. The second discharge port 92 helps to form a continuous air flow so that the upper part of the second collecting part 140 is not blocked by the gender (i.e., the second valve 95 is normally open). That is, in the case of normal operation, a predetermined vacuum pressure (low pressure lower than the atmospheric pressure) is formed inside the vacuum chamber 40 so that the flow of the air flows constantly. Sometimes, if there is too much buildup in the second collecting part 140, it can be used to partially remove it.

The vacuum pump 45 is for forming a vacuum inside the vacuum chamber 40. In a configuration according to an embodiment, the valve 80 can be discharged in a liquid state by the heater 80 and the first valve 90 during a normal operation, and the vacuum chamber 40 can continuously flow the air flow, do. At this time, if the gaseous state passed together with the air is accumulated in the vacuum chamber 40, it can be discharged into the liquid state by natural heat.

When the second valve 95 is instantaneously opened in the state where the second valve 95 is closed and the predetermined vacuum pressure is formed, the high pressure difference causes the leakage in the second trapping part 140 It is easily discharged. A drain port (300) and a drain valve (310) are provided at a lower portion of the vacuum chamber (40) to drain the molten steel into a liquid.

Although not shown, the operation control of the first and second valves 90 and 95 and the operation control of the vacuum pump 45 are performed through a control unit (not shown, for example, a microcomputer or a CPU). In addition, temperature control of the first and second peltiers 20 and 60 is also integrally performed by a control unit (not shown).

Example  action

Hereinafter, a discharge method according to an embodiment of the present invention will be described in detail with reference to FIG. 2 attached hereto. 2 is an operation diagram of the discharge device shown in FIG. 2, the inflow gas 200 including the measurement gas 210, moisture, particulate matter, and the like is introduced into the first cooling tube 10.

As the first peltier 20 is cooled to a temperature of about -30 占 폚, moisture and particulate matter in the inflow gas 200 begin to be generated in the gas 230.

The inlet gas 200 and the outlet 230 then enter the first trapping section 110 of the second cooling tube 70 cooled to a temperature of about -10 ° C. At this time, the water in the inflow gas 200 is completely converted into the sludge 230, and the generated sludge 230 collides with the protrusion 120 and flows through the center hole 130 to the second collecting part 140 do.

The measurement gas 210 from which moisture and particulate matter have been removed through the membrane 230 collides with the protrusion 120 and then moves upward to the gas passage unit 150. The measurement gas 210 passing through the gas passage part 150 downward is transmitted to the analyzer (not shown) through the analyzer port 75. Therefore, the analyzer can analyze the accurate gas component using the measurement gas 210 in an ideal state in which moisture and particulate matter are removed.

As shown in FIG. 2, the gut 230 is accumulated inside the second collecting unit 140. The heater 80 periodically operates to melt the accumulated gaps 230 into liquid 220. When the first valve 90 is opened periodically, the liquid 220 flows downward and is discharged to the outside. The operator can separately store, transport and process these liquids 220.

When the vacuum pump 45 operates, a predetermined vacuum pressure lower than the atmospheric pressure is formed in the vacuum chamber 40. When the second valve 95 is instantaneously opened, a high pressure difference between the second collecting part 140 and the vacuum chamber 40 causes the gaps 230 in the second collecting part 140 to flow into the vacuum chamber 40 ). By performing this process periodically, it is possible to discharge the gender 230.

Alternatively, the molten steel can be drained into the liquid through the drain port 300 and the drain valve 310 under the vacuum chamber 40.

Alternatively, the vacuum pump 45 and the vacuum chamber 40 may be omitted when the entire body 230 is melted. The first valve (90) and the heater (80) may be omitted when discharging the entire body (230) in a vacuum.

The sizes and capacities of the first and second peltiers 20 and 50 can be changed according to the shapes of the first and second cooling tubes 10 and 70.

As this process is repeated cyclically, the liquid and particulate matter can be discharged periodically or at irregular intervals whenever the vacuum pressure is high.

Although the present invention has been described in connection with the preferred embodiments set forth above, it will be readily appreciated by those skilled in the art that various other modifications and variations can be made without departing from the spirit and scope of the invention, It is obvious that all modifications are within the scope of the appended claims.
