Abstract
The utility model relates to a drying dust-cleaning apparatus for a forced air drying section of a chain grate machine, which is characterized in that a hot air pipeline is led out from the forced air drying section of the chain grate machine to be connected with a dust remover and a dust-cleaning fan, two auxiliary air bellows are installed under a feeding end grate bed of the forced air drying section of the chain grate machine and connected with a main exhaust pipeline via the hot air pipeline, a lower part of the feeding end grate bed of the forced air drying section of the chain grate machine is provided with a dust hood connected with the main exhaust pipeline via a dust hood pipeline, the exhaust pipeline connected with the dust remover and the dust-cleaning fan is connected with a high-temperature section of the chain grate machine via the hot air pipeline, and a pipeline is led out from the forced air drying section of the chain grate machine to be connected with the dust remover and the dust-cleaning fan. An electric valve and a thermometer are installed on the pipeline. The utility model has the following advantages: effect of the forced air drying section is ensured, so that a fresh pellet cannot burst in next link for the reason of too much water; production environment in a workshop of the forced air drying section is improved; and environment pollution caused by exhaust emission is reduced.
Description
Technical field
The utility model relates to chain grate machine-rotary kiln pelletizing process medium chain grate apparatus for forced technology field, particularly a kind of dust-removing apparatus for forced air drying section of chain grate.
Background technology
Energy-saving and emission-reduction will run through in the long term among the economic life as a fundamental state policy, have influence on all trades and professions.A plurality of dedusters have been designed in chain grate machine-rotary kiln pelletizing process production line link, these dedusters not only to the process dedusting also to final exhaust gas discharged dedusting, we can say that whole process has fewer environmental impacts, still, the waste gas of chain grate apparatus for forced section is taked the directly way of discharging always.Consider that this part waste gas water content is big, do not have the cleaner that is fit to; Because this part waste gas dustiness is lower, therefore, all think in a very long time to there is no need dedusting again.Following problem before not adopting dust collecting process, chain grate apparatus for forced section is arranged: one, not enough owing to diffusing chimney height, can't provide enough negative pressure that cover waste gas on the blasting drying period is directly all extracted out, this just makes a part of waste gas enter the workshop from chain grate machine feed end or bellows interface and slit, and this part waste gas constitutes very big influence to the production environment in workshop.Because this part EGT at 60～70 ℃, has simultaneously and is being mingled with dust and gives the people's feel to be exactly not only heat but also dirty; Two, because the blasting drying period process characteristic, need up-draught drying fan that the hot waste gas from central cooler is passed the green-ball bed of material from bottom to top, waste gas afterwards need carry moisture that green-ball takes off and discharge on the blasting drying period and cover.But, if there is not the dedusting fan forced draft, only rely on the draft of diffusing chimney can't realize enough negative pressure, such result assembles one section very large waste gas layer of water content in green-ball upper surface space, the water content of the green-ball on these waste gas and chain grate machine grate bed top forms dynamic balance, and just this part green-ball does not only obtain drying and may make the increase of green-ball moisture on the contrary.The a large amount of broken reasons of green-ball in producing before Here it is.At these problems, must improve technology.
Summary of the invention
The purpose of this utility model provides a kind of dust-removing apparatus for forced air drying section of chain grate.
A kind of dust-removing apparatus for forced air drying section of chain grate of the present utility model comprises the deduster, dedusting fan of chain grate machine, the exhaust piping that is connected of deduster, dedusting fan therewith, it is characterized in that:

Adopt the dry dust collecting process process of dust-removing apparatus for forced air drying section of chain grate of the present utility model to be:
1) by the hot air duct of drawing the waste gas of blasting drying period is introduced described dedusting fan, deduster in chain grate apparatus for forced section, utilize dedusting fan and deduster that the waste gas of blasting drying period is carried out dust removal process and forced draft, forced draft helps the moisture of green-ball and deviates from
2) two secondary bellows by under chain grate apparatus for forced section feeding end grate bed, being provided with, these two secondary bellows are connected with main exhaust piping with hot air duct, waste gas in two secondary bellows is introduced main exhaust piping enter cleaner and dedusting fan, guarantee that enough negative pressure pump the waste gas in the secondary bellows fully, guarantee dust removing effects
3) dust excluding hood by being provided with on chain grate apparatus for forced section feeding end grate bed top is delivered to main exhaust piping to the waste gas in the dust excluding hood with pipeline, guarantees that enough negative pressure pump the waste gas in the dust excluding hood fully,
4) with hot air duct chain grate machine high temperature section hot blast is introduced main exhaust piping and enter cleaner and blower fan, guarantee that waste gas has enough temperature and can dewfall., introduce hot blast with pipeline from chain grate machine high-temperature area, reduce the probability of dewfall so effectively.
Advantage of the present utility model:
1) guarantee the blasting drying period drying effect, green-ball enters next link explosion can not take place because moisture is excessive;
2) improve production environment in the blasting drying period workshop;
