Technical Field
The utility model belongs to the technical field of the industrial dust removal, concretely relates to a fan arc transition interface structure that is used for reduction windage of prilling tower, its recovery that is applicable to the urea dust of urea prilling tower.
Background
The urea granulation process can discharge a large amount of tail gas in the production process, the tail gas contains a large amount of urea dust, and the untreated urea dust scatters and settles with the air everywhere to cause serious environmental pollution. In order to solve the problem of tail gas emission pollution of the urea prilling tower, a dry dedusting technology is developed on the basis of a water washing dedusting technology in the past, wherein the dry dedusting technology uses an integral fan to blow and suck for dedusting, namely, the fan is arranged at the top of the urea prilling tower, and air flow is introduced into the urea prilling tower through an induced draft fan. The installation mode of the induced draft fan is as shown in fig. 2, the induced draft fan at the upper part is directly connected to the dust removal air inlet at the lower part through the installation clamping seat 1; by adopting the connection mode, the air flow introduced by the draught fan is directly poured into the dust removal system, namely, the air flow directly enters the large dust removal chamber from the thin pipe, so that the uneven or disordered air flow is caused, and the air flow distribution in the dust removal housing is further influenced.
SUMMERY OF THE UTILITY MODEL
Based on the problems in the prior art, the applicant provides a fan arc-shaped transition interface structure for reducing wind resistance of a prilling tower through multiple designs and researches, and the fan arc-shaped transition interface structure is suitable for recycling urea dust of the urea prilling tower. It has not only improved the air current distribution, has still improved the dust removal effect.
According to the technical scheme of the utility model, a fan arc transition interface structure for reducing wind resistance of a prilling tower is provided, which comprises a convex arc plate and a fan shell assembly, wherein the fan shell assembly is preferably a straight cylinder type fan shell assembly, the straight cylinder type fan shell assembly is connected with a dust removal system through the convex arc plate, the upper end of the convex arc plate is connected with the straight cylinder type fan shell assembly through a clamping end, the extension line of the upper end of the convex arc plate is superposed with the inner wall of the straight cylinder type fan shell assembly,
the extension line of the lower end of the convex arc plate enters the dust removal system.
Furthermore, the arc-shaped transition interface structure of the fan for reducing the wind resistance of the prilling tower further comprises an impeller assembly and a motor assembly, wherein an output shaft of the motor assembly is connected with the impeller assembly and used for converting electric energy into wind energy and promoting airflow to enter a dust removal system.
