Heat recovery device for yellow phosphorus tail gas boiler

Abstract

The invention discloses a heat recovery device for a yellow phosphorus tail gas boiler. The device comprises a heat inlet, a water tank and an outlet; a filter box is arranged on the right side of theheat inlet; a first filter plate is arranged in the filter box; the upper end of the first filter plate is connected with a rubber plug; a sealing pad is fixed at the lower end of the rubber plug; arecovery groove is formed under the first filter plate; a collecting box is arranged under a second filter plate; the water tank is positioned on the right side of a filter box; a steam inlet is formed in the upper end of the water tank; the outlet is positioned at the bottom end of the water tank; and the right side of the water tank is connected with a treatment box. The heat recovery device forthe yellow phosphorus tail gas boiler solves the problem that most heat recovery devices cannot filter hot air, the problem that general heat recovery devices are insufficient in heat utilization andthe problem that the general heat recovery devices directly exhaust gas without performing treatment.

Description

technical field [0001] The invention relates to the technical field of heat recovery devices, in particular to a heat recovery device for a yellow phosphorus tail gas boiler. Background technique [0002] The heat recovery device for the yellow phosphorus tail gas boiler collects and utilizes the heat generated by the combustion of the yellow phosphorus tail gas to reduce energy waste. The existing heat recovery devices on the market often do not filter the hot air, which is likely to cause blockage of the heat pipe. And the general heat recovery device will not fully utilize the heat, resulting in a waste of energy, and most heat recovery devices will directly discharge the discharged gas without processing it, which will easily cause air pollution. The purpose of the present invention is to provide a yellow phosphorus tail gas A heat recovery device for a boiler is used to solve the problems of heat recovery devices currently on the market raised by the above-mentioned bac...
