Abstract
An auxiliary air supply device for a negative pressure dust collection system of a rotary kiln relates to the technical field of chemical equipment and comprises a fan, an air delivery pipe and an auxiliary air pipe. An outlet of the fan is connected with the air delivery pipe, the auxiliary air pipe is fixedly arranged on a dust collection pipeline of the negative pressure dust collection system, one end of the auxiliary air pipe is connected with the air delivery pipe, the other end of the auxiliary air pipe extends into the dust collection pipeline, and the air outlet direction of one end, extending into a dust collection bag, of the auxiliary air pipe is not opposite to the direction of an original dust collection pipeline. Due to the fact that the auxiliary air pipe with an air source is additionally arranged in the dust collection bag, air speed in the original dust collection pipeline is effectively improved, and large particle dust can be blown away from the dust collection pipeline before falling and depositing. The auxiliary air supply device is simple in structure, good in effect, capable of effectively avoid enterprise loss brought by rotary kiln suspend production caused by dust pipeline blockage, easy to popularize and high in popularization value.
Description
Technical field
The utility model relates to technical field of chemical, and the negative pressure dust collecting system that is specifically related to a kind of rotary kiln provides the device of auxiliary wind source.
Background technology
Rotary kiln is widely used in the chiral process, such as the equipment of conduct calcining in adopting rotary kiln, is subjected to fire evenly during calcining, with respect to the calcining of shaft kiln formula, can greatly improve the quality of the product of calcining.But rotary kiln is because of the restriction of its operation principle and institute's converted products, dust collecting system becomes very important part, especially in the today to the environment pay attention to day by day, whether dust collecting system is directly connected to the discharging of enterprise up to standard, and a responsible enterprise, should be devoted to select dust collection effect better, more efficient dust collecting system.Negative pressure is gathered dust as ripe technology, and the enterprise of employing is a lot, but in production reality, the negative pressure dust collection pipe stops up becomes the key factor that impact is produced.After the negative pressure dust collection pipe stops up, rotary kiln is stopped production afterwards dust collection pipe is cleared up, bring larger economic loss to production.Wind speed in the dust collection pipe is the key factor that affects dust collection pipe efficient, and because of the wind speed less, dust is after entering dust collection pipe, and larger particle can produce natural subsidence, thereby is deposited in the dust collection pipe, stops up dust collection pipe, and impact is produced.
The utility model content
For solving above-mentioned negative pressure dust collection pipe blockage problem, the utility model provides a kind of device that prevents larger particles dust natural subsidence.
Rotary kiln negative pressure dust collecting system auxiliary air supply device comprises blower fan, wind conveying pipe, auxiliary airduct, and it is characterized in that: fan outlet links to each other with wind conveying pipe; Auxiliary airduct is fixedly mounted on the dust collection pipe of negative pressure dust collecting system, and the one end links to each other with wind conveying pipe, and the other end probes in the dust collection pipe, probes into not contrary of the air-out direction of dust collecting sleeve one end and the wind direction in the former dust collection pipe.
The utility model can effectively improve the wind speed in the former dust collection pipe by install the auxiliary airduct with wind regime additional in dust collecting sleeve, the dust that makes larger particles before the landing deposition by wind from dust collection pipe.Simple in structure, effective, be easy to promote, have higher promotional value, can effectively avoid stopping up the loss that makes rotary kiln stop production and bring to enterprise because of dust collection pipe.
Description of drawings
Fig. 1: the auxiliary device scheme of installation of buying on behalf of rotary kiln dust collecting system;
Among the figure: 1. the wind direction in the by-pass valve control 2. dust collection pipes 3. former dust collection pipes 4. is assisted airduct 5. wind conveying pipes 6. blower fans.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described:
Rotary kiln negative pressure dust collecting system auxiliary air supply device comprises blower fan 6, wind conveying pipe 5, auxiliary airduct 4, it is characterized in that: blower fan 6 outlets link to each other with wind conveying pipe 5; Auxiliary airduct 4 is fixedly mounted on the dust collection pipe 2 of negative pressure dust collecting system, and the one end links to each other with wind conveying pipe 5, and the other end probes in the dust collection pipe 2, probes into not contrary of the air-out direction of dust collection pipe one end and the wind direction 3 in the former dust collection pipe.
As the improvement of this utility model, described blower fan also comprises a by-pass valve control 1, and by-pass valve control 1 links to each other with blower fan 6, is used for the wind speed that control blower fan 6 is supplied with auxiliary wind.
The auxiliary wind that described auxiliary airduct 4 provides is identical with wind direction 3 in the former dust collection pipe.The auxiliary wind of this type needs a direct-open, increases wind speed in the dust collection pipe 2, prevents the natural subsidence of dust.
For giving full play to the effect of auxiliary airduct 4, the wind direction 3 in described auxiliary airduct 4 and the former dust collection pipe is angle, and the angle span is between positive and negative 90 degree.When the auxiliary wind in the auxiliary airduct 4 enters in the dust collection pipe 2, form certain vortex with original wind, make the dust of natural subsidence leave the dust collection pipe wall, reenter the scope that wind speed can act in the dust collection pipe 2, thereby follow-up wind blows off dust and receives the cleaning that realizes the sedimentation dust, the auxiliary wind of this type only needs time opening a period of time, can prevent the obstruction of dust collection pipe.
The angle of above-mentioned auxiliary airduct and former dust collection pipe wind direction be 30 degree between 60 degree, negative 30 degree are between negative 60 degree time, anti-dust collection pipe obstruction effect is best.
Protection domain of the present utility model is not limited only to the disclosed technical scheme of specific embodiment part, and all technical schemes of auxiliary wind that provides in dust collection pipe all fall into protection domain of the present utility model.
