Description
Technical Field
The utility model relates to the technical field of bag-type dust collectors, in particular to a device for reducing the temperature of inlet smoke of a bag-type dust collector.
Background
The cloth bag dust collector is a dry dust filter which is suitable for collecting fine, dry and non-fibrous dust. The filter bag is made of woven filter cloth or non-woven felt, dust-containing gas is filtered by utilizing the filtering effect of fiber fabric, and when the dust-containing gas enters the bag-type dust collector, dust with large particles and large specific gravity falls down due to the action of gravity and falls into an ash bucket, and when the gas containing finer dust passes through the filter material, the dust is blocked, so that the gas is purified.
With the development of industry, the boiler is increasingly used, most of dust in the flue gas is filtered by adopting a bag-type dust remover, and then the flue gas enters a subsequent dust removing device for further dust removal treatment, and the flue gas is discharged into the atmosphere after reaching the standard. The bag-type dust remover has strict requirements on the temperature of the smoke because of the bag, when the temperature of the smoke is lower than the use temperature, the smoke is easy to condense to generate water vapor, the water vapor is adhered to the bag, and the filtered dust and the water vapor condense on the surface of the bag to influence the subsequent use of the bag, so that the smoke cannot normally pass through the bag and the normal use of a boiler is influenced; when the temperature of the flue gas is too high, the cloth bag can be aged at an excessive temperature, and the fire of the cloth bag can be seriously caused. Therefore, in order to ensure the normal use of the bag-type dust collector, the temperature of the flue gas entering the bag-type dust collector needs to be strictly controlled, and at present, the existing control method comprises the following two methods:
The first is that the flue gas temperature is interlocked, namely, the electric valve is utilized to interlock with the temperature, when the temperature is lower than or higher than the using temperature, the electric valve on the flue gas bypass pipeline is automatically opened, the inlet and outlet valves of the bag-type dust remover are closed, and the flue gas is directly discharged to the next dust removing equipment from the bypass pipeline;
The second is to install a flue gas waste heat utilization device before the bag-type dust collector to reuse the flue gas temperature, thereby reducing the flue gas temperature, but the flue gas waste heat is already effectively utilized before entering the bag, if the flue gas waste heat utilization device is installed again, the temperature is relatively low at first, the utilization value is low, the cost of newly-built equipment is high, the utilization of tail gas preheating is caused to generate low value, the economic level is not cost-effective, the flue gas temperature fluctuation is large, the electric appliance element works frequently, and the service life of the electric appliance element is influenced.
