TABLE 1 spark detection alarm parameters

TABLE 2 spark test Probe parameters

The utility model discloses in the use, when the first time (jar body is empty jar) carries out the use, need to fill a proper amount cooling water to jar in, the volume of filling is 110L, and current level gauge 10 shows that the scale is 48cm (the level gauge 10 range is 50 cm). Under the condition, the internal circulation use condition of the spark extinguishing device can be realized, the consumption of cooling water is reduced, and after the cooling water is consumed (the current 10-degree scale of the liquid level meter is 8 cm), external water supplement can be performed. The spark extinguishing device does not need to be stopped in an external water replenishing link, and water can be replenished without stopping in the using process.

The utility model discloses it is main including following cooling process:

1. heat exchange between surface of guide tube 2 and air

The tail gas in the exhaust pipe of the engine is high-temperature gas, the temperature of the tail gas entering the guide pipe 2 is 360 ℃, the temperature of the air used by the device is about 30 ℃, and the high-temperature tail gas in the guide pipe 2 is in a forced convection heat exchange mode in the pipeline.

2. Heat exchange between tank surface and air

When the surface of the tank body is subjected to heat exchange with air, the high-temperature tail gas extinguishes sparks by self-deflection on the assumption that atomized water is not sprayed in the tank body, and the high-temperature tail gas in the tank only carries out heat exchange with the air through the surface of the tank body. The vertical cylindrical tank is considered as a section of pipe, and the heat exchange is similar to the heat exchange between the guide pipe 2 and air.

3. Heat exchange between cooling water and tail gas

The high-temperature tail gas in the spark extinguishing tank 1 contacts with cooling water to carry out heat exchange, and because the cooling water in the tank is internal circulation, the cooling water can be discharged together with the tail gas in a water vapor form through long-time heat exchange until the cooling water in the tank is consumed completely, and the heat exchange belongs to evaporative heat exchange.

Because of the cooling water is with shower head 6 blowout, forms the atomized water, increase and tail gas area of contact, but the tail gas that the tank inner space flows through is not all to carry out the direct contact heat transfer with the atomized water, so when carrying out the heat exchange, follow that gas cooling release heat approximately equals the evaporation of cooling atomized water and take away the heat and deposit the water absorption heat.

Because the cooling water in the tank is internal circulation, the low-temperature water stored at the bottom can absorb part of heat released by cooling the tail gas in the heat exchange process, so that the temperature of the low-temperature water per se can be continuously increased along with the extension of a time axis until the temperature of the low-temperature water per se reaches a boiling point and keeps constant. Therefore, in the using process, the evaporation capacity of the cooling water in the early stage is far less than that of the cooling water after the temperature is raised.

After the spark extinguishing device is used each time, the residual cooling water in the tank is drained, and the inner surface of the tank and the baffle plate 5 are washed, so that the phenomenon that harmful components such as sulfide, nitride, dust, peroxide and the like dissolved in water form acid liquor to corrode the tank body and other parts is avoided.

The above is only the preferred embodiment of the present invention, not to the limitation of the present invention in any form, all the technical matters of the present invention all fall into the protection scope of the present invention to any simple modification and equivalent change of the above embodiments.
