Recovery device for condensed water

Abstract

The invention discloses a recovery device for condensed water, which is arranged on the precipitation end of a baker roller of an inclination type pipeline and is connected with a cast steel shaft collar of the baker roller and a shaft sealing pipe communicated with the cast steel shaft collar. The recovery device for condensed water comprises a plurality of groups of pumping pipe groups and an outflow pipeline which can regulate air pressure, wherein the pumping pipe groups comprise at least one outflow hole, a collection tank and a pumping elbow pipe; the outflow hole is annularly arranged on the roller wall of the precipitation end of the baker roller; the collection tank is arranged on the outer wall of the precipitation end of the baker roller and is communicated with the outflow hole; both ends of the pumping elbow pipe are respectively connected with the collection tank and the cast steel shaft collar; the bending direction of the pumping elbow pipe is the same as the gyratory direction of the baker roller; and the outflow pipeline comprises a condensed water high-pressure pipeline, a condensed water overhead pipeline and a tee branching pipe, and the tee branching pipe is respectively connected with the shaft sealing pipe, the condensed water high-pressure pipeline and the condensed water overhead pipeline. The invention can be matched with a large inclination type roller to rotate, continuously discharges condensed water in the baker roller and enhances the efficiency of drying coal blocks.

Description

technical field [0001] The invention relates to a recovery device, in particular to a condensed water recovery device used on an inclined pipeline dryer. Background technique [0002] Raw pulverized coal is mainly dried by jar dryers in the briquetting factory, and disk dryers are still used in the old operating equipment. The production efficiency is low and it is not conducive to large-scale production. A kind of inclined pipe dryer is proposed at present (see figure 2 ), through the drying pipes distributed in the large inclined drum 8 to dry the briquettes, which greatly improves the efficiency of drying the briquettes. [0003] In this drying equipment, the timely removal of condensed water is very important, which can help to speed up the coal drying operation. But in this device, because the drum 8 is constantly rotating during the drying operation, the existing condensed water recovery device cannot cooperate well with it, so it is necessary to develop a condensed ...
