Install the condensate collection device and include a water seal structure, and ensure that when the outlet of the condensate collection device is blocked, the collection device is in a sealed state, no combustion smoke will be discharged from here, and ensure that the equipment is shut down safely. The existing condensate collection device consists of upper and lower covers, water inlets, drains, electrodes, etc. When the drain is blocked, the condensate cannot be discharged. At this time, the condensate will accumulate in the channel of the condensate collection device. When the condensate When the two electrodes are in contact, the electrodes will conduct and the equipment will stop safely. This structure requires that the channel of the collecting device must be a sealed structure; some condensate collecting devices only have a water-sealed structure to prevent the smoke from being discharged from this channel, but there is no Safety protection mechanism, when the drain is blocked, the condensate will fill the entire channel of the collection device and cause backflow, causing safety hazards.

Embodiment one

As shown in Figure 1, the schematic diagram of the condensate collection device described in this embodiment, the condensate collection device is provided with a water inlet 10, a condensate collection chamber for collecting and placing condensate, connected with the water inlet 10 and extending into the condensate collection The water inlet pipe 110 of the cavity, and the drain port 50 for discharging condensate. The top of the condensate collection chamber is covered with an upper cover 20 and a lower cover 30 , the upper cover 20 and the lower cover 30 are arranged in parallel and can be connected by fasteners or the like, and there is no need for a seal between the two. Wherein the upper cover 20 and the lower cover 30 are provided with the same shape and corresponding first openings corresponding to the water inlet pipe 110, and are used to pass the water inlet pipe 110. The connections between the water inlet pipe 110 and the first opening are all sealed connections, and there is a Mechanisms such as sealing rings to enhance the sealing effect. Preferably, the water inlet pipe 110 is integrally connected with the upper cover 20 as one piece.

A partition 730 is provided in the condensate collection chamber, which is a thin plate and is located in the middle of the condensate collection chamber. The partition 730 protrudes upward from the bottom of the condensate collection chamber, and its height is lower than the lower surface of the lower cover 30. Divide the condensate collection chamber into a first chamber 710 and a second chamber 720, and form a gap space between the lower cover 30 and the lower cover 30, which is the condensate overflow port 740, the first chamber 710 and the second chamber Chamber 720 communicates only through condensate overflow 740 .

The condensate collection chamber on one side provided with the water inlet pipe 110 is the first chamber 710, and the first chamber 710 receives the initial water intake of the condensate from the condensing equipment. The condensate connected by the water inlet pipe 110 of the water inlet 10 settles and accumulates in the first chamber 710. When the accumulated height reaches the vicinity of the condensate overflow port 740, it will overflow to the second chamber 720, and the bottom of the second chamber 720 is set There is a drain port 50 through which the overflowing condensate is discharged out of the device. The second chamber 720 is also equipped with a safety protection mechanism. When the drain outlet 50 is blocked and cannot drain water, the safety protection mechanism will be triggered to give an alarm or automatically trigger the switch, so as to achieve the purpose of safety protection. The water column of the water inlet pipe 110 and the accumulated water column of the first chamber 710 form a coherent water body that isolates the external air from the air in the condensate collection device, which can be used to resist the change of pressure difference in the condensate collection chamber, prevent external air from entering and The condensate is discharged to achieve the effect of water seal. For equipment that may have flue gas, the water sealing effect of the condensate collection device is more important to prevent the flue gas from escaping. The height ratios of the water inlet pipe 110 , the condensate collecting chamber and the partition 730 are obtained through many tests and calculations, and the optimal height ratio is selected to ensure the best water sealing effect.

There is a sewage outlet 60 at the bottom of the first chamber 710. Since the first chamber 710 is the water inlet side, the inflowing condensed water will accumulate and precipitate here, and some impurities in the condensate will be deposited at the bottom, and the sewage outlet will be opened regularly. 60 can carry out sewage.

Embodiment two

This embodiment is a further description of the first embodiment above. As shown in FIG. 1, the safety protection mechanism is an air conduction unit and a triggerable unit 430 connected to each other, and the air conduction unit is a lower air cavity connected sequentially from bottom to top 40. The connecting air pipe 410 and the upper air chamber 420, the lower air chamber 41, the connecting air pipe 410 and the upper air chamber 420 are uniform cylindrical structures, and the upper end of the upper air chamber 420 is connected with the triggerable unit 430. The upper cover 20 and the lower cover 30 are provided with a second opening corresponding to the air conduction unit, the second opening of the upper cover 20 is used to pass through the connecting air pipe 410, the second opening of the lower cover 30 is used to pass through the lower air chamber 40, and the air conduction unit The connection mode with the second opening is a sealed connection, and a sealing ring and other mechanisms to enhance the sealing effect are arranged at the opening. Wherein, the lower air cavity 40 is in sealing contact with the lower surface of the upper cover 20 without any gap.

The connecting air tube 410 is used to connect the upper air chamber 430 and The lower air cavity 40 forms a closed atmospheric structure. One end of the connecting air tube 410 protrudes from the lower air cavity 40 and penetrates the upper cover 20 , and the other end is seamlessly sleeved in the upper air cavity 420 . Here, the cross-sectional area of the upper air chamber 420 is smaller than or equal to the cross-sectional area of the lower air chamber 40 , and the cross-sectional area of the connecting air pipe 410 is smaller than the cross-sectional area of the upper air chamber 420 . Preferably, the cross-sectional shapes of the lower air chamber 40 , the connecting air pipe 410 and the upper air chamber 420 may be the same or different, as long as the joints of the air chambers are sealed. The lower air chamber 40, the connecting air pipe 410 and the upper air chamber 420 form an integrated air pressure structure. The lower air chamber 40 bears the liquid surface pressure from the second chamber 720 and transmits it to the upper air chamber 420. The upper air chamber 420 The unit 430 is triggered upon receipt of the conducted pressure.

The specific principle of the safety protection mechanism is as follows:

Since the pressure and volume of the lower air chamber 40 and the upper air chamber 420 have the following proportional relationship: P1*V1=P2*V2 (P is pressure, V is volume), so when the lower air chamber 40 is continuously subjected to compression from the liquid surface, When the pressure P1 increases, V1 gradually decreases. At the same time, for the upper air chamber 420, V2=S*H (S is the cross-sectional area of the air chamber, and H is the height of the air chamber). When H is fixed, the unit can be triggered When the installation position of 430 is fixed, the volume V2 of the air cavity is also fixed. As the condensate level rises, P2 gradually increases. When the pressure is greater than the action point of the trigger unit 430, it will trigger the safety shutdown of the heating and hot water equipment, which plays a role in safety. Protective effects.

Embodiment three

This embodiment is a further limitation of the second embodiment above, and the triggerable unit 430 is a water level switch or a water pressure sensor. When the drain port is blocked and cannot drain smoothly, the water level of the second chamber 720 will continue to rise, and compress the air chamber of the safety protection mechanism to realize pressure transmission, trigger the water level switch to stop safely, or trigger the water pressure sensor to alarm.
