Abstract
The utility model provides a two combustion chamber flue gas emergency door sealing device, includes the vertical setting of the export section of emergency door, and its below is equipped with sealed basin, is equipped with water in the sealed basin, and the tip of export section is located under the liquid level of sealed basin, and the liquid level department of sealed basin is equipped with the overflow hole, the one end of overflow hole intercommunication overflow pipe, the other end intercommunication water tank of overflow pipe, the water tank is equipped with the water pump, the one end of the export intercommunication moisturizing pipe of water pump, the other end intercommunication sealed basin of moisturizing pipe. Compared with the prior art, the technical effect of the utility model is that, the utility model discloses sealing is the water seal, and when the indoor pressure of second combustion is great, the water seal can be broken to the indoor gas of second combustion, and the rapid escape does not destroy the water seal moreover.
Description
Technical Field
The utility model relates to a second combustion chamber flue gas emergency door sealing device.
Background
The second combustion chamber among the useless system of burning of danger is essential equipment at present, and it passes through flue intercommunication exhaust-heat boiler, through exhaust-heat boiler's draught fan's attraction, and the second combustion chamber high temperature flue gas after the burning passes through the flue and gets into exhaust-heat boiler, and the second combustion chamber is the negative pressure. However, in order to prevent the failure of the induced draft fan or the flue, the secondary combustion chamber is communicated with an emergency door, a sealing device is arranged at an outlet section of the emergency door, and the sealing device is not opened in a normal state; when a fault occurs, the sealing device is opened to communicate with the outside, so that the excessive pressure in the secondary combustion chamber is avoided, and the protection effect is achieved.
SUMMERY OF THE UTILITY MODEL
The utility model discloses the technical problem who solves: the opening of the sealing device is cumbersome.
The technical scheme of the utility model specifically does:
the utility model provides a two combustion chamber flue gas emergency door sealing device, includes the vertical setting of the export section of emergency door, and its below is equipped with sealed basin, is equipped with water in the sealed basin, and the tip of export section is located under the liquid level of sealed basin, and the liquid level department of sealed basin is equipped with the overflow hole, the one end of overflow hole intercommunication overflow pipe, the other end intercommunication water tank of overflow pipe, the water tank is equipped with the water pump, the one end of the export intercommunication moisturizing pipe of water pump, the other end intercommunication sealed basin of moisturizing pipe.
Compared with the prior art, the technical effect of the utility model is that, the utility model discloses sealing is the water seal, and when the indoor pressure of second combustion is great, the water seal can be broken to the indoor gas of second combustion, and the rapid escape does not destroy the water seal moreover.
Drawings
Fig. 1 is a schematic view of the usage state of the present invention.
Fig. 2 is a schematic diagram of the present invention.
Detailed Description
The present invention will be described in detail with reference to the accompanying drawings and specific embodiments thereof.
As shown in fig. 2, a second combustion chamber flue gas emergency door sealing device, including the outlet section 12 vertical setting of emergency door, its below is equipped with sealed basin 20, be equipped with water 21 in the sealed basin 20, the tip of outlet section 12 is located the liquid level of sealed basin 20, the liquid level department of sealed basin 20 is equipped with overflow hole 22, overflow hole 22 communicates the one end of overflow pipe 23, the other end of overflow pipe 23 communicates water tank 30, be equipped with water pump 31 in the water tank 30, the export of water pump 31 communicates the one end of moisturizing pipe 32, the other end of moisturizing pipe 32 communicates sealed basin 20.
The working principle is as follows:
during normal operation, as shown in fig. 1-2, the water pump 31 is continuously operated, the second combustion chamber 10 is communicated with the emergency door 11, the end part of the outlet section 12 is positioned below the liquid level of the sealed water tank 20, the second combustion chamber 10 is at negative pressure, the liquid level (see reference numeral 13) of the water column of the outlet section 12 is higher than the liquid level of the sealed water tank 20, and when the pressure in the second combustion chamber 10 changes, the height of the water column of the outlet section 12 also changes, and when the height of the water column becomes higher, water is sucked from the sealed water tank 20; when the height of the water column becomes low, the water in the sealed water tank 20 flows into the sealed water tank 20.
If the water in the sealed water tank 20 is excessive, the water enters the water tank 30 through the overflow hole 22 and the overflow pipe 23. Therefore, the liquid level of the sealed water tank 20 can be kept stable, the sealed water tank 20 forms a water seal, and when the secondary combustion chamber 10 works normally, the sealed water tank 20 prevents external air from entering the secondary combustion chamber 10.
When the draught fan or the flue fails, the pressure in the secondary combustion chamber 10 is increased, part of the gas forces the water column of the outlet section 12 to completely enter the sealed water tank 20, and part of the gas escapes from the sealed water tank 20, the emergency door 11 is opened, the pressure in the secondary combustion chamber 10 is reduced, the excessive pressure in the secondary combustion chamber is avoided, and the protection effect is achieved.
It should be noted that:
the second combustion chamber 10 is only several meters away from the outlet section 12, the temperature of the outlet section 12 is high, the damage of the emergency door pipeline can be accelerated, after the water circulation is formed at the position of the sealing water tank 20, the sealing water tank 20 can perform the effect of other cooling water, the temperature of the outlet section 12 and even the temperature of the whole emergency door 11 are reduced, and the service life of the emergency door is prolonged.
See the prior art for additional details.
While the preferred embodiments of the present invention have been described, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the general inventive concept, and it is intended to cover all such changes and modifications as fall within the true spirit and scope of the invention.
