The saturated cooling tower of the grinding dust collector is used to instantly cool the high-temperature flue gas to the corresponding saturation temperature by spraying a large amount of water into the high-temperature flue gas with a liquid-gas ratio up to 1 ~ g/m3. In the high-temperature flue gas wet purification system, such as the converter gas purification system, this cooling device is generally used. In addition to cooling down, it also plays a role of coarse dust removal. A large amount of dust is collected by water to form sewage into the sewage treatment system. Overflow Venturian tube in converter wet purification system is a typical device of saturation cooling.
The dust removal device of electric furnace adopts the bag filter, that is, the dust removal system is dry dust removal, requiring high-temperature flue gas cooling with dry cooling or not saturated cooling. So saturated cooling tower equipment is not suitable for electric furnace and other dry dust removal.
Grinding dust collector evaporating cooling tower
Grinding dust precipitator evaporative cooling tower through to the high temperature flue gas gush are appropriate particles mixed gas water, high temperature flue gas cooling in an instant into the corresponding unsaturated air, at the same time of cooling also have the effect of coarse dust, the dust is frozen into larger dry particles sedimentation in ash bucket of water, no water problem of secondary pollution and the energy consumption of the compulsory blowing cooler and cooling pipe clogging problem.
The cooling tower of grinding dust collector is mainly used for dry dust removal system, which can be used together with bag dust collector and electrostatic dust collector. According to the process form and dust removal scheme, the design of cooling tower can be generally divided into cooling water as the medium and the mixture of air and water as the medium of the cooling tower design requirements of cooling water as the medium of the evaporation cooling tower. The flue gas enters from the top or lower part of the tower and is discharged from the bottom or top discharge part. The spray device is designed to spray smoothly, that is, the cooling water mist flows in the same direction as the airflow.
Grinding, polishing, dust removal, typhoon cooling is the most simple cooling method. It is to set another cold air inlet on the duct before the inlet of the dust collector to suck the ambient air into the duct and mix it with high-temperature flue gas, so that the mixed temperature can be reduced to the set temperature to achieve the purpose of cooling the flue gas.
In the practical application of direct air cooling, automatic regulating valve and temperature sensor should be set at the entrance of cold air
To control the opening time of the regulator to control the amount of cold air intake. The temperature sensor should be located at a distance of more than 5m before the cold air inlet.
This method is usually applied to low temperature (200 ℃) and request the small amount of cooling, or by other means is to still can not meet the requirements after high temperature flue gas temperature drop dramatically, and in this way as to prevent the accident of supplementary measures to cool high temperature, as to prevent accidental most widely used high temperature.
Grinding and polishing dust removal bench mixing air valve
Grinding and polishing dust removal table mixed air valve, also known as cold air valve, is mainly used for dust removal system with unstable air flow temperature, so that the dust removal equipment temperature control operation within the set range, so as to improve the service life of the equipment, ensure the normal operation of the system. The mixed air is generally installed in the bag filter when the flow temperature is higher than the control temperature, the mixed air is opened and mixed into the air duct in front of the cold air mouth. When the air flow temperature is lower than the control temperature, the mixing valve automatically closes.
