Description

TECHNICAL FIELD [0001] The present invention relates to a condensate water treatment apparatus for a condensing boiler,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a condensate water treatment apparatus installed in a condensing boiler exhaust pipe, and more particularly, to a condensate water treatment apparatus which is simple in installation and is easy to install and repair.

A boiler is a device configured to heat the heat generated by burning fuel through a heat exchanger and to use the heated water as heating or hot water.

Such a boiler generates exhaust gas at about 250 캜 while burning fuel, and the high temperature exhaust gas is directly discharged to the outside, which causes a problem that the thermal efficiency is not high.

Recently, a boiler has a sensible heat exchanger for directly absorbing the heat of the burner and a latent heat exchanger for absorbing heat in the combustion air in order to increase the heat efficiency. The boiler having the sensible heat exchanger and the latent heat exchanger is called a condensing boiler.

In the condensing boiler having the above structure, the exhaust gas is condensed and a large amount of condensed water is generated. Since the condensed water contains acidic substances such as CO ₂ , NO x and SO x contained in the exhaust gas, the condensed water has a strong acidity.

Condensate water treatment equipment for neutralizing condensate flowing down the boiler exhaust pipe is installed in the boiler because acidic condensation of the strong acid is drained to the sewer as it can acidify the river ecosystem and the surrounding environment .

Since the conventional condensate water treatment apparatus is installed inside the boiler, maintenance and repair are very troublesome and difficult because the boiler must be disassembled to maintain and repair the condensate water treatment apparatus.

The connection pipe 101 is formed in the shape of a double pipe with an outer pipe 103 and an inner pipe 102 formed inside the outer pipe 103.

An upper portion of the inner tube 102 formed to have a smaller diameter than the outer tube 103 is protruded upward from the lower end of the outer tube 103, The upper portion of the inner pipe 102 is formed into an inner wall shape in the outer pipe 103 to form a groove-like condensate collecting portion 115 between the outer pipe 103 and the inner pipe 102 .

A condensed water discharge pipe 107 is formed outside the outer pipe 103 so as to communicate with the condensed water collecting unit 115 and a condensed water discharge pipe 107 is formed outside the inner pipe 102 to communicate with the inside of the inner pipe 102 108 are formed.

The cover 112 covering the cup 114 filled with the neutralizing agent for neutralizing the condensed water is fastened to the reaction water discharge pipe 107 and the condensed water inflow pipe 108 of the connection pipe 101.

The cover 112 covers the upper part of the cup 114 filled with the neutralizing agent and closes the cup 114. The cover 112 is provided at one side of the cover 112 with a condensed water discharge pipe 111 And a condensed water inflow pipe 109 penetrating the upper portion of the cover 112 and extending to an inner lower portion of the cup 114 is formed on the cover 112. [

The condensed water inflow pipe 109 of the cover 112 is connected to the condensed water discharge pipe 107 of the connection pipe 101 through a releasable attachment means and the condensed water discharge pipe 111 of the cover 112 is connected to the connection pipe 101, To the condensate inlet pipe (108) of the connection pipe (101).

It is preferable to completely seal the space between the cover 112 and the cup 114 by inserting a rubber ring 113 between the cover 112 and the cup 114. [

The cover 112 and the cup 114 are fastened together by using various fastening means which are easily detached and attached so that the cup 114 can be easily detached and attached from the cover 112.

The condensed water treatment process of the condensed water treatment apparatus 100 according to the present invention will be described in detail.

When the boiler 10 is operated, exhaust gas is generated and the exhaust gas is exhausted to the outside through the exhaust pipe 11 and the integrated exhaust pipe 12. In this process, a large amount of strongly acidic condensed water is generated in the exhaust pipe 11.

The condensed water flows down on the inner wall of the exhaust pipe 11 installed in the vertical shape to reach the connection pipe 101 and condensed water other than the connection pipe 101 rides on the inner wall of the outer pipe 103 connected to the exhaust pipe 11 And flows into the condensate collecting part 115 formed in a groove shape between the outer pipe 103 and the inner pipe 102.

The condensed water which has been accumulated in the condensed water collecting part 115 flows along the condensed water discharge pipe 107 of the connection pipe 101 communicated with the condensed water collecting part 115 and flows into the condensate water inflow pipe 107 of the cover 112 connected to the condensed water discharge pipe 107 Condensate flows along the tube 109 into the lower portion inside the cup 114.

Alkaline neutralizing agent is filled in the cup 114. As the condensed water flows into the lower portion of the inside of the cup 114 along the inlet pipe 109, the condensed water level rises in the cup 114, The condensed water flows into the connection pipe 101 through the condensed water inflow pipe 108 communicated with the inner pipe 102 of the connection pipe 101. [

As described above, the strong acid condensate flows from the lower part of the cup 114 to the upper part, and is neutralized by the neutralizing agent filled in the cup 114.

The neutralized condensed water flowing into the inner pipe 102 of the connection pipe 101 flows down the inner pipe 102 of the connection pipe 101 and flows into the boiler 10 and flows into the boiler 10 The introduced neutralized condensed water is installed inside the boiler 10 and discharged to the outside through a condensate collecting device (not shown).

A condensing water collecting device (not shown) installed in the boiler 10 is a well-known technology, and a detailed description thereof will be omitted.

In the embodiment of the present invention as described above, the condenser water collecting apparatus is constructed in the boiler 10, and the condenser water collecting apparatus is installed in the boiler 10 Is a condensate water treatment device for the case where no water is used.

The other embodiment of the present invention shown in FIG. 5 is the same as the entire embodiment of the present invention shown in FIG.

However, the condensed water inflow pipe 108 is not formed in the inner pipe 102 of the connection pipe 101, and the condensed water discharge pipe 111 of the cover 112 is not connected to the connection pipe 1010.

The condensed water processed according to another embodiment of the present invention configured as described above is configured to be discharged to the outside without flowing into the connection pipe 101 through the condensed water discharge pipe 111.

Since the condensed water treatment apparatus according to the present invention can be easily installed in the existing boiler exhaust pipe 11, the condensate water treatment apparatus 100 can be installed in a conventional boiler without a condensate treatment apparatus.

In addition, since the neutralizing agent for neutralizing strong acidic condensed water is filled in the cup 114, the neutralizer can be easily replenished or replaced simply by removing the cup 114 from the cover 112 when the neutralizer is replenished or when the neutralizer is replaced Maintenance and repair is very easy.

At this time, it is preferable that the cup 114 is formed of a transparent material so that the operator can visually recognize the filler state or foreign matter deposition inside the cup 114 with the naked eye from the outside.
