Description

Condensate water disposal device of boiler

The present invention relates to a condensate treatment apparatus of a boiler, and more particularly, in the condensate neutralization and automatic discharge device of a heat recovery type boiler (aka condensing boiler), by forming a non-drift means on the side of the condensate storage container, condensate water wall It is invented to increase the condensate treatment efficiency and prevent environmental pollution by forming a flow path that can be in direct contact with the neutralizing member without drift toward.

In general, a heat recovery type boiler refers to a boiler designed to facilitate condensation heat exchange by installing a burner on the top or side of a heat exchanger to make the combustion gas flow downward and to lower the dew point temperature.

Unlike the Bunsen type boiler, this heat-absorbing boiler adopts a porous premixing method and installs a heat exchanger immediately after the flame surface to suppress the generation of nitrogen compounds and emit less carbon monoxide. Since it absorbs sensible heat first and latent heat discharged to exhaust gas secondly, the temperature of exhaust gas of general boiler is 150-260 ℃, whereas heat absorption boiler recovers heat by 50-120 ℃. High heat of more than% can be obtained.

And, in such a heat absorption boiler, water vapor contained in exhaust gas condenses below the dew point temperature and is discharged to the outside of the heat exchanger. Since the acidity of the condensate is about pH2.8-pH3.5, the acid condensate If it comes in contact with the components constituting the component, there is a risk of corrosion, and if such acid condensate is discharged to the sewer as it may cause environmental pollution.

Therefore, in order to prevent such condensed water from causing corrosion or other environmental pollution problems, a dilution method of increasing the pH by supplying a certain amount of dilute water to the condensed water was used.

In addition, a neutralization device for neutralizing condensing gas boiler condensate using magnesium (Mg), potassium (K) and sodium chloride (Nacl) has been proposed in Korean Utility Model Registration Nos. 1998-20222 and 1998-20228. have.

The dilution method of increasing the pH by supplying dilution water to the condensate in the condensate treatment apparatus of the conventional condensing boiler configured as described above has the advantage of easy operation in terms of boiler control and easy maintenance after boiler installation, while condensate at pH 3 In order to dilute the pH to 5 or more, a large amount of dilution water of about 100 times or more of the amount of condensate is required, resulting in large waste of resources and boundary loss due to excessive use of dilution water.

In addition, the configuration proposed in the Korean Utility Model Registration Application Nos. 1998-20222 and 1998-20228 for neutralizing the condensing water boiler condensate using magnesium (Mg), potassium (K) and sodium chloride (Nacl). The actual neutralization effect is not very satisfactory, and because it is a hydrophobic substance, if the reaction with water is too fast, there is a high possibility of the secondary safety risk due to the generation of hydrogen gas during the reaction.

Then, in order to compensate for the above disadvantages, the solid natural neutralization (eg shell, basic, mineral, coral, eggshell, etc.) is pulverized and charged into a container having a certain size and shape, and the condensed water is passed through the container. It has been proposed to neutralize acidic condensate by contacting condensate with the surface of neutralizing material.However, in the early stage of neutralization treatment, the condensed water has good flow and good water permeability due to voids between pulverized solid neutralizing material. The effect is kept constant, but when a large amount of condensate passes or passes for a certain period of time, the voids between the neutralizing substances are filled or reduced by the flow of neutralizing substances in the container according to the flow of the condensate, and the filling density of the neutralizing substances in the bending container is increased. This increases the water permeability due to fine powder granulation and impairs the flow of condensate, resulting in clogging. It was.

In addition, when the solid neutralizing material is in the form of small balls or beads, the porosity of the ball or beads is somewhat affected by the size of the balls or beads.

In this case, in the initial stage of neutralization, neutralization is well performed by uniformly contacting the entire surface of the neutralizing material, but after a certain time, the condensate flow does not evenly contact the entire surface of the solid phase neutralizing material in the container, Drift phenomenon that flows along the surface or the wall of the container may occur, resulting in an unstable state in which the neutralization effect is inferior or not neutralized at all.

In addition, even when the neutralization performance is poor or the blockage occurs, the parts themselves are not exposed to the outside, so consumers are not easily able to identify them, and the replacement time due to the deterioration of the neutralization performance of the neutralization materials according to the amount of condensate generated. There was a difficult problem to know.

In the condensing gas boiler, the neutralization apparatus for condensate is necessary in consideration of the environmental aspects, and when the life of the boiler is estimated to be 7 years or more, the condensate drift problem greatly impairs the nature of the neutralization treatment. Therefore, it is very important to keep the effect constant or to prevent drift due to the adverse effect.

SUMMARY OF THE INVENTION An object of the present invention is to provide a condensate dilution and automatic discharge device of a heat recovery type boiler (aka condensing boiler), by forming a drift preventing means on the side surface of the condensate storage container so that the condensate can be directly contacted with the neutralizing member without drift toward the wall. It is to provide a condensate treatment device for a boiler to increase the condensate treatment efficiency and prevent environmental pollution by forming a flow path.

The object of the present invention is located on the bottom surface of the heat exchanger 10 of the boiler with a predetermined width and size, so that the condensate storage chamber 21 inside the body so as to neutralize and discharge the condensate generated during boiler operation. A condensate storage container 20 having a condensate inlet 22 formed at an upper portion of the body at a central portion of the condensate accommodating chamber 21, and a housing 23 formed at an inner portion of the body;

It is installed in the housing 23 of the condensate storage container 20, the receiving portion 31 is provided inside the body, the discharge port 32 is formed in communication with the inner bottom surface of the receiving portion (31). A plug member 30;

The neutralizing member 40 is installed in the accommodating part 31 of the plug member 30 to be in contact with the condensate when the condensate is discharged to neutralize the condensate.

Both sides of the wall surface 33A of the inner housing portion 31 of the plug member 30 have a predetermined step, and a plurality of protrusion preventing means 33 are formed to protrude in a direction corresponding to each other. .

Therefore, in the condensate treatment apparatus of the present invention, condensed water flows down the wall surface on both sides of the housing 31 of the plug member 30 for accommodating the neutralizing member 40 inside the boiler member. Since it is not in contact with the non-drift preventing means 33 is formed to prevent falling, since the condensate can form a flow path that can more easily contact the neutralizing member 40, the condensate is generated The problem can be solved.

Therefore, the reliability and the merchandise of the product can be improved.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a schematic configuration diagram showing an installation state of the condensate treatment apparatus of the present invention boiler.

Figure 2 is an exploded perspective view showing a state in which the deflection prevention means is formed in the plug member of the condensate treatment apparatus of the present invention.

3 is a front sectional view showing the internal shape of the condensate treatment apparatus of the present invention boiler.

That is, in the condensate treatment apparatus of the boiler of the present invention as shown in Figures 1 to 3 inside the housing 23 formed in the condensate storage chamber 21 of the condensate storage container 20 inside the body accommodating portion 31 Plug member 30 is provided on the wall surface (33A) of the () is the deflection prevention means (33).

The plug member 30 is in contact with the condensed water introduced into the body, a neutralizing member 40 is installed to neutralize the acidic condensate discharged.

The neutralizing member 40 is set differently according to the characteristics of the product and the characteristics of the product, etc. In the configuration of the present invention has a diameter of a predetermined size (about 0, 5 ~ 10mm), is formed in a spherical shape It is used by applying the neutralizing member 40 made in the form of ceramic balls (Beads) or beads (Beads) particles.

Accordingly, in the case of the spherical neutralizing member (ceramic ball, beads particles) as described above, the neutralizing member 40 is generally filled in the receiving portion 31 of the plug member 30 by less than about 40 to 70%. As a result, after a certain period of time, the neutralization effect rapidly decreased due to the drift phenomenon, or there was a lung lung that could not be neutralized at all.

That is, since the ceramic balls, beads particles, etc. used as the neutralizing member 40 is molded to have a spherical shape, when filled in the accommodating part 31 of the plug member 30, the condensed water neutralizing member 40 because the porosity is large. The entire surface of the c) is not evenly contacted, and a drift phenomenon occurs in which only one surface of the ceramic ball, the beads, or only one wall of the accommodating part 31 flows.

Therefore, the condensate drift preventing means 33 of the present invention is formed in a plurality of zigzag shapes in a direction corresponding to each other with a predetermined step on both sides of the wall surface 33A of the accommodating portion 31 of the plug member 30.

2 and 3, since the guide jaw 34 having a predetermined length and thickness is formed as the deflection preventing means 33, the plug member 30 through the condensate storage container 20 is used. As the condensate flowing into the accommodating portion 31 of the drop down, it is possible to prevent the phenomenon that the condensed water is deflected in a certain direction, that is, only one direction by the guide jaw 34, which is the deflection prevention means 33 when the drift occurs. It is.

As a result, the condensate that has been deflected and dropped by the guide jaw 34, which is the deflection preventing means 33, is moved from the wall surface direction to the center by the guide jaw 34, thus delaying the falling time of the condensate neutralizing member 40. ), The neutralizing effect can be increased.

In addition, since the guide jaw 34, which is the deflection preventing means 33, has a predetermined step and is formed in a zigzag shape with respect to the mutually corresponding directions, the condensed water that has been dropped and dropped in the lateral direction by the guide jaw 34 is formed. While moving toward the center portion, since the contact with the surface of the neutralizing member 40 evenly to maximize the neutralizing effect of the condensate.

In addition, the length of the guide jaw 34, which is the deflection preventing means 33, is formed to have a length that can be close to the center of the accommodating portion 31 of the plug member 30, and the retardation portion 36 of the plane to the upper portion of the body. Is preferably formed.

This, the length of the guide jaw 34 is formed to be close to the central portion of the accommodating portion 31 filled with the neutralizing member 40, the condensed water introduced by the retardation portion 36 of the upper portion of the retardation portion 36 Since it is possible to increase the contact time with the neutralizing member 40 by delaying the falling time by, the length of the guide jaw 34 is preferably used to form a length that can be close to the central portion.

In addition, as illustrated in FIGS. 4A and 4B, the drift preventing means 33 may use the guide jaw 34 by forming a predetermined inclined portion 35 with respect to the downward direction. The delay portion 36 may be formed at the end of the inclined portion 35 to be used.

That is, the condensate generation amount is different according to the characteristics and characteristics of the product, the condensate flowing into the neutralizing member 40 is more easily introduced into the neutralizing member 40 to increase the contact time and area, the guide jaw ( 34 may be used to form an inclined portion 35, and a concave portion 36, that is, a flat portion is formed at the end of the inclined portion 35, so that the condensed water easily introduced by the concave portion 36 is formed. It is possible to secure a flow path that can be in contact with the neutralizing member 40 more easily.

Therefore, in the condensate treatment apparatus of the present invention, the guide jaw 34 which prevents the drift of the condensate from the wall surface of the accommodating part 31 of the plug member 30 in which the neutralizing member 40 is accommodated is predetermined. Since the step is formed in a zigzag shape, when the condensed water is introduced and the drift occurs, the guide jaw 34 converts the condensed water into the center so that the condensed water can be contacted with the neutralizing member 40 more easily. Therefore, the neutralization effect of condensate can be increased.

According to the configuration of the present invention as described above, since the guide jaw, which is the anti-drift means, is formed in a zigzag shape with a predetermined step on the wall surface of the housing of the plug member in which the neutralizing member is embedded, the condensed water that has been drift-dried evenly on the surface of the neutralizing member Since it can contact, a neutralization effect can be increased.

In addition, by modifying the flow of the condensate by the drift prevention means during the drift movement of the condensate, it is possible to improve the water permeability and the durability of the boiler as well as the effect of the neutralization treatment.

In addition, since the flow path may be modified so that the acidic condensed water may evenly contact the entire surface of the solid ceramic ball or the bead-shaped neutralizing member by the surface tension of the water, the neutralizing effect of the condensed water may be continuously maintained.

Therefore, it is a very useful invention that can improve the reliability and marketability of the product, and can prevent environmental pollution.
