Online waste removing system for waste discharge area of plate type SCR denitration catalyst calcinator
2014
The invention discloses an online waste removing system for a waste discharge area of a plate type SCR denitration catalyst calcinator. The problems that in the prior art, dust and volatile matters in a calcinator are easily condensed and adsorbed to the inner wall of a gas flue, and product quality is affected are solved. The online waste removing system is characterized in that a gas flue vertical branch pipe (5) is arranged on the top of a body, in the waste discharge area, of the calcinator; a side flue gas discharge port is connected with a flue gas header pipe (3) through a connecting branch pipe provided with a butterfly valve (4); the top of the gas flue vertical branch pipe (5) extends upwards to form a blind plate provided with a waste removing device; the waste removing device is composed of a circular scraping plate (8), a lifting rod (1) and a handle (7); the circular scraping plate (8) is arranged in the gas flue vertical branch pipe (5), the center of the circular scraping plate (8) and the bottom of the lifting rod penetrating through the blind plate (2) are welded into a whole, and the top of the circular scraping plate (8) is provided with the handle (7). The online waste removing system has the advantages of being reasonable in structure, easy to operate, safe, environmentally friendly, efficient, high in quality and the like; waste adsorbed on a pipeline in production can be effectively removed in time, it is guaranteed that flue gas is pumped and discharged smoothly, the qualified rate of products are increased, and therefore the online waste removing system is worth popularizing.
