BACKGROUND OF THE INVENTION
The present invention relates to a condensed water neutralizing device for neutralizing acidic condensed water generated in a heat exchanger or the like.
[0002]
[Prior art]
Condensation water neutralization equipment for neutralizing acidic dew condensation water generated in heat exchangers, etc., in order to ensure a sufficient contact time between the neutralizing agent and dew condensation water using a compact container It is necessary to make the water passage sufficiently long by zigzag or the like. For this purpose, a partition wall for forming the zigzag passage is required in the container of the neutralization tank. Moreover, the structure for preventing the neutralizing agent from flowing out together is necessary in the vicinity of the outlet where the condensed water after the neutralization treatment exits from the neutralization tank. Further, in the space near the inner bottom portion of the neutralization tank constituting a part of the zigzag passage, there is a configuration in which a strainer or the like for separating the neutralizing agent and the neutralization reaction product so as not to settle and accumulate is arranged. Necessary.
Conventionally, in order to configure a neutralization tank having the above-described functions, a plurality of structural members are generally adhered to the rough neutralization tank configured earlier by bonding or other methods. The method of joining and further assembling the whole neutralization tank was taken. For this reason, the number of assembling steps is increased and the structure is complicated, but the cost is increased.
[0003]
[Problems to be solved by the invention]
As a method for solving the above problems, the present inventors decided to form the neutralization tank by blow molding with a resin. However, for example, when a blow-molded hollow portion is appropriately cut to form a container-shaped main body case, there has been a problem that the side wall of the main body case easily falls down. As a measure for preventing the side wall from falling down (inward), a reinforcing rib can be formed on the side wall near the upper end opening of the main body case. However, such a reinforcing rib is sufficient. In addition, in order to reduce the tendency of falling with only such reinforcing ribs, the rib height had to be considerably increased.
On the other hand, it is necessary to prevent the neutralizing agent from flowing out together when the condensed water that has been neutralized is discharged from the container-shaped main body case. Conventionally, however, a strainer or net with many holes is separately provided. There is a problem that the neutralizing agent leaks due to detachment or misalignment. In addition, assembly costs were added.
In addition, in the conventional neutralization device, when attaching the case lid to the container-like case main body from above, the case main body is provided with a hook projection, and the hook opening provided on the case lid is provided on the case main body. There was something that was fitted and engaged, but since the whole hooking port provided on the case lid was a flat surface, the hooking port was easily detached from the hooking projection In addition, since the hooking opening and the hooking protrusion are not sufficiently in contact with each other, there is a problem that rattling is likely to occur even after the case lid is attached to the case body.
Furthermore, in a conventional neutralization device, a strainer is arranged in the space near the inner bottom of the neutralization tank, so that the neutralizing agent and neutralization reaction products that have settled accumulate on the inner bottom of the neutralization tank and block the passage. In order to prevent this, the strainer is configured to be pressed from above using a separate member so that the strainer does not move upward. However, since a separate part is required, there is a problem in terms of the number of parts or assembly cost. was there.
[0004]
Therefore, the present invention eliminates the drawbacks of the conventional dew condensation water neutralization device, and even when produced using a blow molding method, it can have a strength that can sufficiently prevent the container-like case body from falling down, The number of parts can be reduced sufficiently, and the neutralizing agent and neutralization reaction product can be prevented from leaking out of the outlet or accumulated in the bottom of the case body and blocking the passage with a reduced number of parts. It is another object of the present invention to provide a dew condensation water neutralization device that can prevent the case main body from being easily detached or rattling when the case main body is covered with a case lid.
[0005]

This is the fifth feature.
  Moreover, the condensed water neutralization apparatus of the present invention has a sixth feature that, in addition to any one of the first to fifth features, the case body is a resin blow molded product..
[0006]
According to the first feature, the zigzag passage partition wall of the condensed water formed in the container-shaped main body case is protruded from the opposite side walls of the case main body and is integrally formed with the tips of the pair of partition wall constituting pieces. Since the parts are configured to be abutted against each other, the zigzag passage partition wall is formed as a separate part by simultaneously forming the partition wall constituting piece integrally when forming the main body case. There is no need for separate configuration.
In addition, among the zigzag passage partition walls, each zigzag passage partition wall where the condensed water passes under the partition wall needs to be heightened so that the condensed water does not overflow without darkness. The projecting base end part of the pair of partition wall constituent pieces constituting the tall zigzag passage partition wall is configured integrally with the reinforcing rib formed on the inner side wall near the upper edge opening of the case body so as to be integrated with the case. The main body is prevented from falling down and the case body is strong. Of course, each of the pair of partition wall constituting pieces has a height (height) that decreases from the projecting base end portion to the projecting tip end portion, so that a ventilation space is formed above the zigzag passage partition wall. It is possible to ensure a smooth flow by promoting pressure equalization between the respective parts, and also to ensure a flow to the outlet side due to overflow even when condensed water is blocked in the middle of the case body.
[0007]
According to the second feature, in addition to the function and effect of the first feature, the last zigzag passage partition wall adjacent to the outlet of the condensed water is composed of a pair of partition wall constituting pieces that respectively protrude from both side walls. In addition, a slit such as a strainer or wire mesh is attached separately so that a slit that allows the liquid to pass is formed so that the protruding tip portions of the pair of partition wall constituent pieces face each other with a gap. The neutralizer and the neutralization reaction product can be prevented from flowing out as a part of the main body case.

[0015]
Referring to FIGS. 1 to 3, 10, and the like, the dew condensation water neutralizing device includes a container-like case body 10 and a case lid 20. A dew condensation water inlet 21 is provided at one end of the dew condensation water neutralizer.
[0016]
Referring to FIGS. 2 to 9, the main body case 10 is configured in a container shape, and the inner space thereof is partitioned by the zigzag passage partition walls 11, 12, 13, so that one end side of the case main body with the inlet 21 is formed. A zigzag passage P that zigzags in the vertical direction toward the outlet 14 on the other end side is configured. Condensed water moves from the inlet 21 to the outlet 14 through the zigzag passage P, and is neutralized by the neutralizing agent G (see FIG. 3) disposed in the zigzag passage P.
A reinforcing rib 15 projects from the inner wall near the upper edge opening of the main body case 10 and is integrally formed. Specifically, the reinforcing ribs 15 are formed so as to protrude inwardly on the side walls of the long side walls 10a and 10a of the main body case 10. Although not provided on the short side walls 10b and 10b, they may be provided similarly.
[0017]
The zigzag passage partition walls 11, 12, 13 are each composed of a pair of partition wall constituting pieces 111, 111, 122, 122, 133, 133.
Each partition wall constituting piece 111, 111, 122, 122, 133, 133 is integrally formed so as to protrude inward from the long side walls 10 a, 10 a of the main body case 10.
Among the zigzag passage partition walls 11, 12, 13, the zigzag passage partition walls 11, 12 excluding the last zigzag passage partition wall 13 adjacent to the outlet 14 are protruding tip portions 111 a of the partition wall constituting pieces 111, 111, respectively. , 111a and the protruding tip portions 121a and 121a of the partition wall constituting pieces 121 and 121 are configured to abut against each other. In the case of resin blow molding, this contact is substantially in a bonded state substantially at the contact portion.
[0018]
Of the zigzag passage partition walls 11 and 12 excluding the last zigzag passage partition wall 13 adjacent to the outlet 14, the zigzag passage partition wall 11 on which the condensed water passes below the partition wall has a height In order to prevent the condensed water from overflowing the zigzag passage partition wall 11 without darkness, the passage is short-circuited. On the other hand, by leaving the ventilation space Q above the zigzag passage partition wall 11, pressure equalization between the zigzag passages P is promoted to ensure a smooth flow, and the condensed water is zigzag in the case body 10. When the passage P is blocked in the middle, it is necessary to ensure the flow toward the outlet 14 by causing an overflow. From such a demand, even if the zigzag passage partition wall 11 is made taller, it is necessary to slightly lower the height near the center.
In the situation as described above, the tall zigzag passage partition wall 11 is configured such that the partition wall constituting pieces 111 and 111 have the protruding base end portion 111b higher than the protruding tip end portion 111a. That is, it is inclined so that the height decreases from the protruding base end portion 111b to the protruding tip end portion 111a.
The protruding base end portions 111 b and 111 b of the partition wall constituting pieces 111 and 111 of the tall zigzag passage partition wall 11 are provided on the inner wall near the opening of the case body 10 and are continuous with the reinforcing rib 15. In this way, it is integrally molded.
In this way, by integrally forming the protruding base end portion 111b of the partition wall constituting piece 111 continuously with the reinforcing rib 15, the strength of the case main body 10 as a container is greatly improved, and the inner side of the side wall of the case main body 10 is increased. Falling down can be sufficiently prevented.
The effect of preventing the inward collapse is particularly great when the case body 10 is formed by blow molding with a resin material by cutting the middle of the hollow portion.
[0019]
2 to 4 and the like, with respect to the zigzag passage partition wall 13 adjacent to the outlet 14, the protruding tip portions 131a and 131a of the pair of partition wall constituting pieces 131 and 131 constituting the zigzag passage partition wall 13 are used. Are configured so as to face each other without contacting each other, thereby forming a slit S.
The slit S has a gap size that allows condensed water to pass through but does not allow the neutralizing agent G or the neutralization reaction product to pass through.
Since the slit S is configured in accordance with the integral molding of the partition wall constituent pieces 131, 131, the filter function can be performed without using a conventionally used wire mesh or strainer, and without performing assembly work. Can be configured.
[0020]
Next, attachment of the case body 10 and the case lid 20 will be described.
The case main body 10 and the case lid 20 are attached by providing a plurality of hooking projections 16 on the upper outer wall of the case main body 10 and hooking mouth portions at portions corresponding to the hooking projections 16 of the case lid 20. 22 is provided.
Referring to FIGS. 2, 7, 9 to 11, etc., the hooking projection 16 protrudes downward at a gentle angle from its upper end, and is pulled out so that its lower end is a right angle or a slight acute angle. A stop returning portion 16a is formed.
On the other hand, referring to FIGS. 10, 11, 12 and the like, the hooking portion 22 has a locking piece warped outward with respect to the surrounding surface at the lower edge of the hooking portion 22. 22a is constituted.
With this configuration, when the case lid 20 is put on the case main body 10 and externally fitted, each hooking opening 22 of the case lid 20 fits into each hooking projection 16 of the case main body 10, and The retaining piece 22a of the mouth portion 22 is fitted against the retaining return portion 16a of the hooking projection 16, and the retaining portion 22a warped to the outside is fitted. It abuts on 16a and is locked. This prevents the case lid 20 from being easily detached from the case body 10 and eliminates backlash between the case lid 20 and the case body 10.
The case lid 20 can be made of metal. By being made of metal, the strength can be ensured even if the thickness of the case lid 20 is reduced. Further, since the locking piece 22a of the hooking portion 22 can have elasticity and strength, it can be firmly and sufficiently locked to the retaining return portion 16a of the hooking protrusion 16.
[0021]
Next, the structure which attaches the strainer 30 in the case main body 10 is demonstrated.
Referring to FIGS. 5, 13, 14, and the like, the strainer 30 is disposed so as to fit in the space near the inner bottom portion of the case body 10, so that the neutralizing agent G and the neutralization reaction product are applied to the strainer 30. This prevents the zigzag passage P from being blocked by being separated into an upper region and collecting on the inner bottom of the case body 10. The strainer 30 includes a main body flat plate portion 31 in a porous state and a pair of leg portions 32 and 32 extending downward from two opposite sides of the main body flat plate portion 31. The strainer 30 can be made of metal, for example.
The size of the main body flat plate portion 31 that is fitted in the space near the inner bottom portion of the case body 10 is similar to the horizontal cross-sectional shape of the inner space near the inner fixed portion of the case main body 10 where the main body flat plate portion 31 is arranged. And
The pair of leg portions 32, 32 is provided in a state of hanging from the two sides of the main body flat plate portion 31, and the lower lower half portion 32a is bent from the middle of the leg portion 32 so as to be inclined inward. Has been. The bending angle α of the lower half portion 32a is, for example, an angle smaller than 45 degrees.
[0022]
On the other hand, protrusions 17 for preventing the removal are integrally formed on the inner walls of at least two opposing side walls 10a, 10a near the inner bottom of the case body 10 where the strainer 30 is to be disposed. The protrusion 17 can be integrally formed on the side walls 10a and 10a as a rib protruding from the inner wall.
The inclination angle β of the upper half of the protrusion 17 is the same as the bending angle α of the lower half 32a of the leg 32, and the angle γ of the lower half of the protrusion 17 is greater than 45 degrees.
And the gap dimension of the protrusion parts 17 and 17 which oppose both sides is comprised so that it may become a little smaller than the width W of the main body flat plate part 31 of the strainer 30 (the dimension between the two sides where the leg part 32 is provided).
Now, when the strainer 30 is lowered into the case body 10 with the pair of leg portions 32 facing down, first, the lower half portion 32a of the leg portion 32 of the strainer 30 reaches the upper half portion of the protruding portion 17, The descending resistance increases while descending along the inclination angle β of the upper half. However, the strainer 30 is shaped so as to gradually push the side walls 10a, 10a of the case body 10 with the leg portion 32 whose lower half portion 32a is narrowed, and gets over the protruding portion 17 and fits into the lower space. When the leg 32 reaches the inner bottom, the leg is stabilized.
Once the strainer 30 is placed below the protruding portion 17 and has a lower slope, the inclination angle γ of the lower half of the protruding portion 17 is larger than 45 degrees, so that it can easily escape upward. Disappears and stabilizes at that position.
Therefore, by integrally forming the protruding portion 17 on a part of the side wall 10a of the case body 10, the strainer 30 can be surely disposed and prevented from coming off, so a special member is separately prepared and the strainer 30 is pressed from above. There is no need to do so.
[0023]
In the embodiment of the present invention, the main body case 10 is molded from a resin that is resistant to the neutralizing agent G and acidic dew condensation water, but can be molded by blow molding in particular. This is because even if the case body 10 is molded by blow molding, the case body 10 can be prevented from falling down.
[0024]
Still another embodiment of the present invention will be described with reference to FIG. The zigzag passage P configured in the case body 10 is configured by the zigzag passage partition walls 11, 12, and 13. Of the zigzag passage P, the first tank P on the inlet 21 side is provided.₁And the first tank P₁2nd tank P adjacent to₂The zigzag passage partition wall 11 that divides the space between the two and the second tank P₂And third tank P₃The zigzag passage partition wall 12 that divides the space between the two is configured to have a low height. 3rd tank P₃And 4th tank P₄The zigzag passage partition wall 11 between the two heights is again increased.
On the other hand, by setting the position of the slit S of the zigzag passage partition wall 13 adjacent to the outlet 14 to the same level as the zigzag passage partition wall 12 having a low height, the water level of the condensed water in the case body 10 at the normal time L is set to be slightly higher than the zigzag passage partition wall 12 having a low height.
Further, the neutralizing agent G is filled up to the upper position (not exceeding the higher zigzag passage partition wall 11) sufficiently beyond the vicinity of the upper end of the low zigzag passage partition wall 12 having the water level L. I am doing so.
[0025]
With the configuration as described above, when the neutralizing agent G is reduced by the neutralization reaction, the neutralizing agent G on the upper side moves downward due to gravity and is replenished to the reaction section. Thus, a stable neutralization reaction is possible over a long period of time. Also, with this type of configuration, there has been a problem that the condensed water passage is clogged with the reaction product generated by the neutralization reaction.₁However, in the case of the present invention, the first tank P₁And second tank P₂Zigzag passage partition wall 11 between and the second tank P₂And third tank P₃The zigzag passage partition wall 12 between the first tank P and the₁1st tank P when clogged under₁Water level and second tank P₂There is a large difference in the water level, and the head pressure difference increases the force to flow against clogging, and the neutralization reaction product can be easily washed away.
Also, the first tank P₁Even if the lower part of the tank is completely clogged, the first tank P₁And second tank P₂The condensed water overflowing from the upper end of the zigzag passage partition wall 11 between the second tank P and the adjacent second tank P immediately without reacting.₂And third tank P₃Without going over the zigzag passage partition wall 12 between the second tank P₂3rd tank P after reacting with neutralizer G at the top of₃Therefore, there is also an effect that inconvenience discharged from the outlet 14 in an incomplete neutralized state is reduced.
[0026]
Still another embodiment of the present invention will be described with reference to FIGS. In this embodiment, a water level sensor 40 in which two electrodes 41, 41 are suspended in the case body 10 is disposed on the case lid 20. The pair of electrodes 41 of the water level sensor 40 is suspended to the upper space in the case body 10 so that the water level of the dew condensation water exceeds the normal water level L and is detected when the water level rises abnormally. It is composed.
When the abnormal water level detection by the water level sensor 40 continues for a certain time or more, the control unit in the hot water supply apparatus (not shown) that receives the detection information of the water level sensor 40 determines that the clogging is caused by the neutralization reaction product. I have to.
By determining that the neutralization reaction product is clogged, the control unit of the hot water supply device is configured to notify an abnormality of the neutralization device through a remote controller of the hot water supply device, or prohibit the use of the hot water supply device. Constitute.
The determination of clogging with the neutralization reaction product is made when the detection of the abnormal water level continues for a certain time or more. Even if there is no clogging due to neutralization reaction products, etc., clogging may occur due to freezing during cold weather. In this case, freezing will be thawed by the flow of condensed water, and clogging due to freezing will soon be released. Because it is done. In order to eliminate the case of clogging due to freezing, it can be performed by setting a certain duration, for example, 30 minutes.
Of course, the temperature sensor that detects the temperature of the dew condensation water, the temperature in the neutralization device, and the temperature in the vicinity of the neutralization device is used only when the temperature sensor falls below the freezing danger temperature (for example, 2 ° C.). Such clogging by reactive organisms may be determined on the condition that the continuation is for a long time of 30 minutes or more. In the case of a temperature exceeding the freezing danger temperature, clogging with a neutralization reaction product is performed under a condition of a relatively short duration such as several seconds to several tens of seconds so as not to make a false detection due to shaking of the water surface. Can be determined.
