However, in the conventional exhaust gas drain water treatment apparatus having the above-described structure, there is a portion in front of the filter where the drain water that has flowed in is retained, so that sludge containing oil is present in this portion. Collect. For this reason, the sludge accumulated in front of the filter cannot be removed just by replacing the filter.Therefore, there is a problem that it is necessary to remove the accumulated sludge at the same time as the filter is replaced. The development of an exhaust gas drain water treatment device was a challenge.

[0005]

As a concrete means for solving the problems of the prior art, the present invention uses an engine driven by gas or oil as a fuel as a power source and also heats the exhaust gas. In an exhaust gas drain water treatment device used in a system constructed for effective use, a filter is installed in a bottomed cylindrical shape at the drain water inlet part formed with an opening on the upper surface, and between the filter and the drain port. An exhaust gas drain water treatment device, characterized in that an alkaline neutralizing agent is installed in

Further, by providing an exhaust gas drain water treatment device characterized in that an alkaline neutralizing agent is installed between the filter and the drain port, the above-mentioned problems of the conventional art are solved.

[0007]

[Function] Acidic drain water, which is condensed from exhaust gas and contains sludge and oil, is filtered by a bottomed cylindrical filter provided at the drain water inlet opening upward and then with an alkaline neutralizing agent. It is neutralized by contact and drained from the drain. It is filtered by a bottomed cylindrical filter,
The sludge and oil collected here are all taken out when taking out the bottomed tubular filter, so there is no need to perform the work of removing sludge and oil again.

[0008]

Embodiments of the present invention will now be described in detail with reference to the drawings. It should be noted that the portions having the same functions as those of the conventional technique shown in FIG.

The inside of the container body 1 is partitioned by a partition wall 5A having a small hole 5a formed on the entire surface and a partition wall 5B having a small hole 5b formed on the upper 1/4, for example, and the flow of drain water flows in. The inlet 2, the neutralization chamber 3, and the outlet 4 are all connected in a state where the upper surface is open.

A cylindrical filter 6 having a bottom is removably inserted and installed in the inflow port 2, and the filter 6 comes out from above at an opening 61 when the gas engine heat pump air conditioner or the like is operated. The drain water condensed from the exhaust gas is configured to flow down and be introduced through the drain water introducing pipe 7.

Into the neutralization chamber 3, a drain water introduction pipe 7 flows into the inflow port portion 2 and is filtered by a filter 6 to form a partition wall 5A.
The well-known alkaline neutralizing agent 8, which is known as calcium carbonate or magnesium carbonate for neutralizing drain water that has entered through the small holes 5a, is loaded.

The outlet 4 is a spare chamber for draining drain water neutralized in the neutralization chamber 3, and a drain water discharge pipe 9 is provided in the middle part of the outlet 4. Nothing is particularly provided in the outflow port 4, and when the drain water flowing from the drain water introducing pipe 7 is neutralized and drained, the neutralizing agent 8 is added to the partition wall 5B. Even if the neutralizing agent 8 is discharged to the outlet 4 through the small hole 5b, the neutralizing agent 8 stays at the bottom of the outlet 4 and does not cause the inconvenience of flowing out from the apparatus. There is.

In the exhaust gas drain water discharge device having the above structure, the exhaust gas emitted from the engine (not shown) is cooled by the exhaust gas heat exchanger (not shown) and the like, and the water vapor contained in the exhaust gas is contained. The drain water generated by condensation of the water flows into the inflow port 2 through the drain water introducing pipe 7, and the sludge and oil contained in the drain water are filtered out by the filter 6, so that only water is contained. It flows into the neutralization chamber 3.

The drain water flowing into the neutralization chamber 3 is stored in the partition wall 5
Since the small holes 5b of B are stored there until reaching the height at which the small holes 5b are bored, the time of staying in the neutralization chamber 3 is long and the neutralizing effect of the neutralizing agent 8 is large.

The drain water neutralized by contacting the neutralizing agent 8 in the neutralization chamber 3 enters the outlet 4 through the small holes 5b of the partition wall 5B and is drained by the drain water drain pipe 9. It

When a problem such as clogging of the filter 6 occurs due to long-term use, only the filter 6 is pulled up, and the sludge and oil filtered off here are all pulled up together with the bottomed filter 6, and Since the inner wall of the inflow port 2 of the container 1 can be prevented from being contaminated with sludge or the like, the maintenance work can be performed very easily.

As for the inflow port 2, as shown in FIG. 2, a punching metal having a small hole 5c on the entire surface is separated from the side plate 1a and the bottom plate 1b of the container body 1 by a predetermined distance, for example, 2 cm. 5C is installed, and if the drain water introduced from the drain water introducing pipe 7 into the opening of the filter (not shown) installed here is configured to be filtered from the four sides and the bottom, the filtration speed is increased. Therefore, there is an advantage that the partition wall 5A does not need to be wide.

Further, as shown in FIG. 3, the filter locking means 1c is installed at a predetermined distance from the side plate 1a of the container body 1, for example, 1 cm.
When the filter 6A having the shape shown in FIG. 4 and the filter 6B having the shape shown in FIG. 5 are installed in c as shown in FIG. 6, not only the filter can be easily manufactured, There is also an advantage that the work of setting the filter becomes easy. Also in this case, if the bottoms of the filters 6A and 6B are provided so as to be separated from the bottom of the container body 1, there is an advantage that the filtration speed is improved.

Further, a partition wall 5D having an opening such as a small hole 5d in the lower portion is installed on the upstream side of the partition wall 5B, and the neutralization chamber 3
If the drain water sunk at the bottom of the tank is provided so as to flow into the outlet 4, there is an advantage that the effect of preferentially discharging the drain water neutralized by the alkaline neutralizing agent 8 becomes greater. In this case, the partition wall 5B may be removed and only the partition wall 5D may be installed.

Further, the inflow port 2, the neutralization chamber 3, and the outflow port 4
It is also possible to install an appropriate lid on each of them so that they can be opened and closed.

The materials of the filters 6, 6A, 6B are cloth, non-woven fabric, glass fiber, synthetic fiber, activated carbon,
Conventionally known materials such as natural fibers formed from porous ceramics, wood or paper are used.

Since the present invention is not limited to the above embodiments, various modifications can be made without departing from the spirit of the claims.
