Abstract
A water seal of a cooler of a combined air handling unit comprises a combined air conditioner, wherein a water dripping disc is arranged below a surface cooler of the combined air conditioner, a water outlet at the bottom of the water dripping disc is connected with an inlet of a first horizontal water sealing pipe, an outlet of the first horizontal water sealing pipe is connected with an inlet at the upper part of a first vertical water sealing pipe, an outlet at the lower part of the first vertical water sealing pipe is connected with an inlet of a second horizontal water sealing pipe, an outlet of the second horizontal water sealing pipe is connected with an inlet at the lower part of the second vertical water sealing pipe, an outlet at the upper part of the second vertical water sealing pipe is connected with a drain pipe, and a check valve is arranged on the second horizontal water sealing; the utility model makes the water seal quickly established through the check valve, and avoids the excessive condensed water from being brought into other functional sections of the unit; the check valve makes the unit in a sealed state, so that air with radioactive substances is prevented from entering a room.
Description
Technical Field
The utility model relates to a combination formula air handling unit technical field, in particular to combination formula air handling unit cooler water seal.
Background
At present, cold water is introduced into a surface cooler of a combined air handling unit for refrigeration in summer by a ventilation system of a nuclear power station, and hot air flows through the surface cooler for cooling so as to achieve the refrigeration effect. The surface temperature of the surface cooler is lower than the saturation temperature of water vapor in the air, when hot air flows through the surface cooler, condensed water can be generated, a water dripping disc is arranged at the bottom of the surface cooler to catch the condensed water, and the condensed water is discharged through a water seal assembly connected to the water dripping disc.
Taking a nuclear-grade combined air processing unit (hereinafter referred to as a unit) of a master control room as an example, condensed water is generated at a negative pressure section of the unit, after the condensed water is generated, the negative pressure inside the unit is counteracted through a water column with a height difference of two vertical water seal pipes, when the pressure of the water column with the height difference is greater than the negative pressure inside the unit, the water flows out of the unit, and the part is referred to as a water seal.
The existing water seal has the following defects: in the refrigeration in summer, less condensed water is generated at the beginning, and due to negative pressure in the unit, outside air can be sucked into the unit through the water seal, so that the water seal cannot be established quickly, the water seal cannot be established all the time in extreme conditions, water in a drip tray is accumulated a lot, and a motor and a cable are immersed in the water, thereby bringing risks to the safe operation of the unit; if nuclear leakage occurs on site, the air sent into the main control room needs to pass through the purification unit firstly and then is sent into the air conditioning unit, the water seal is a leakage point and is in negative pressure, the air with radioactive substances directly enters the main control room through the water seal without passing through the purification unit, radiation damage is caused to main control personnel, and further expansion of nuclear accidents is influenced.
Disclosure of Invention
In order to overcome the defects of the prior art, the utility model aims to provide a combined water seal for a cooler of an air handling unit, which is quickly established to ensure that an air conditioner is always in a sealing state.
In order to achieve the above purpose, the utility model discloses the technical scheme who takes does:
the utility model provides a modular air treatment unit cooler water seal, including combined type air conditioner 1, the below of combined type air conditioner 1's surface cooler 2 is equipped with drip tray 3, 3 bottom delivery ports of drip tray and the entry linkage of first horizontal water seal pipe 4, the export of first horizontal water seal pipe 4 and the entry linkage on 5 upper portions of first vertical water seal pipe, the export of 5 lower parts of first vertical water seal pipe and the entry linkage of 6 of second horizontal water seal pipe, the export of 6 of second horizontal water seal pipe and the entry linkage of 7 lower parts of the vertical water seal pipe of second, the export and the drain pipe connection on 7 upper portions of the vertical water seal pipe of second, install check valve 8 on 6 of second horizontal water seal pipe.
The check valve 8 is a swing check valve.
The utility model has the advantages that:
1. the water seal is quickly established through the check valve 8, so that excessive condensate water is prevented from being brought into other functional sections of the unit;
2. the unit is sealed by means of a non-return valve 8, preventing air with radioactive substances from entering the room.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
The present invention will be described in detail with reference to the following differences.
Referring to fig. 1, a combined type air handling unit cooler water seal comprises a combined type air conditioner 1, a water dripping disc 3 is arranged below a surface cooler 2 of the combined type air conditioner 1, a water outlet at the bottom of the water dripping disc 3 is connected with an inlet of a first horizontal water sealing pipe 4, an outlet of the first horizontal water sealing pipe 4 is connected with an inlet at the upper part of a first vertical water sealing pipe 5, an outlet at the lower part of the first vertical water sealing pipe 5 is connected with an inlet of a second horizontal water sealing pipe 6, an outlet of the second horizontal water sealing pipe 6 is connected with an inlet at the lower part of the second vertical water sealing pipe 7, an outlet at the upper part of the second vertical water sealing pipe 7 is connected with a drain pipe, a height difference water column of the second vertical water sealing pipe 7 and the first vertical water sealing pipe 5 offsets negative pressure inside the combined type air conditioner 1, and a check valve 8 is arranged.
The check valve 8 is a swing check valve.
The utility model discloses a theory of operation does:
when the unit just begins to operate, the check valve 8 is closed under the action of negative pressure, the first vertical water seal pipe 5 is filled with water along with the increase of condensed water, the check valve 8 is flushed when the water can overcome the negative pressure, and the water flows to the outside of the unit, so that the water seal can be established quickly. The check valve 8 enables the unit to be always in a closed state, and even if radioactive substances exist in the air, the radioactive substances cannot enter the main control room through the water seal.
