Abstract
The invention discloses a rotary kiln waste gas dust removal system which comprises a cooler, a bag-type dust remover and an exhaust fan. The output end of the cooler is connected with the input end of the bag-type dust remover, and the output end of the bag-type dust remover is connected with the exhaust fan. The rotary kiln waste gas dust removal system further comprises a gas uniformizing device, wherein the output end of the gas uniformizing device is connected with the input end of the cooler, the gas uniformizing device comprises a shell and a spiral stirrer, and the spiral stirrer is rotatably installed in the shell. The rotary kiln waste gas dust removal system can conduct uniformizing processing on waste gas before dust removal is conducted, the temperature of the waste gas is uniformized, and the dust removal efficiency is ensured.
Description
Technical field
The present invention relates to a kind of rotary kiln waste gas dedusting system.
Background technology
The height of rotary kiln tail kiln discharge EGT is the key factor affecting consumption of raw materials.When under kiln type and calcining materials stable condition, the operation of kiln discharge EGT and kiln has much relations.As undue intensified operation, the heating load of kiln is too much, and heat can not make full use of, and kiln tail gas temperature is raised, and causes unit of fuel consumption to increase, dedusting difficulty.
Enter the calcining in kiln of kiln raw material and can produce decomposition, when the small grain size proportion of the material that point to ungird is larger or when entering that in kiln material, content of powder is higher, dust content in stack gas is higher.Add that in rotary kiln production, material and waste gas are reverse movements, when gas flow rate in kiln improves, it is significantly inevitable that waste gas takes dust quantity, and therefore, rotary kiln tail dust content in stack gas is very large, is generally 20-30g/m
3, maximumly reach 70-80g/m
3.Thus, need to carry out dedusting to revolution kiln tail gas.The structure of dust arrester of the prior art is: comprise cooler, sack cleaner and air exhauster, the output of cooler is connected with the input of sack cleaner, the output of sack cleaner is connected with air exhauster, after waste gas is discharged from rotary kiln, first enter into cooler to lower the temperature, the waste gas exported from cooler carries out dedusting by sack cleaner again, finally to be taken away by gas by air exhauster and is transported to diffusing chimney.This processing mode due to the temperature of gas exported from rotary kiln not too even, after subcooler cooling, the temperature approach of waste gas obviously increases especially, and therefore, waste gas, when carrying out dedusting by sack cleaner, has influence on the effect of dedusting.
Summary of the invention
For above-mentioned technical problem, the invention provides a kind of rotary kiln waste gas dedusting system, the present invention can carry out uniform treatment to waste gas before dedusting, makes the equalizing temperature of waste gas, guarantees the efficiency of dedusting.
Technical scheme of the present invention is as follows:
Rotary kiln waste gas dedusting system, comprise cooler, sack cleaner and air exhauster, the output of cooler is connected with the input of sack cleaner, the output of sack cleaner is connected with air exhauster, also comprise an equal device of air, the output of this equal device of air is connected to the input of cooler, and described equal device of air comprises housing and spiral agitator, and described spiral agitator is installed in rotation in housing.
Have employed such scheme, also comprise an equal device of air, the output of this equal device of air is connected to the input of cooler, and described equal device of air comprises housing and spiral agitator, and described spiral agitator is installed in rotation in housing.After waste gas streams enters into housing, by the stirring of the spiral agitator in equal device of air, waste gas streams is mixed in the housing fully, thus makes the temperature of waste gas streams and entrained dust homogenising, contribute to follow-up sack cleaner like this and dedusting is carried out to waste gas.
Described sack cleaner is reverse-suction wind-bag type dust remover, this reverse-suction wind-bag type dust remover comprises the housing with air inlet and gas outlet, distributor is provided with in shell air inlet side, the middle part of housing is provided with dirt pocket, filter bag is provided with in this dirt pocket, filter bag is by spring suspended, and back suction air-valve is located at the top of housing and is communicated with dirt pocket.Waste gas streams can be made evenly to be diffused in dirt pocket by distributor, can the filter bag in dirt pocket be cleared up by back suction air-valve, to guarantee the efficiency of dedusting.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
The structural representation of Fig. 2 sack cleaner;
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is further described.
See Fig. 1, rotary kiln waste gas dedusting system of the present invention, comprises cooler 1, sack cleaner 2 and air exhauster 3, and the output of cooler 1 is connected with the input of sack cleaner 2, and the output of sack cleaner 2 is connected with air exhauster 3.Also comprise an equal device of air, the output of this equal device of air is connected to the input of cooler 1, and described equal device of air comprises housing 4 and spiral agitator 5, and described spiral agitator 5 is installed in rotation in housing 1.Described sack cleaner 2 is reverse-suction wind-bag type dust remover, this reverse-suction wind-bag type dust remover comprises the housing 21 with air inlet and gas outlet, distributor 22 is provided with in shell air inlet side, the middle part of housing is provided with dirt pocket 23, filter bag 24 is provided with in this dirt pocket, filter bag is suspended in midair by spring 25, and back suction air-valve 26 is located at the top of housing and is communicated with dirt pocket 23.
