Problems solved by technology

[0005] Traditionally, when replacing the filter element, the filter is manually disassembled from the pipeline and then removed. After replacing the filter element, the filter is moved to the installation position and connected to the pipeline. However, due to the filter volume of the waste heat boiler Often heavy and heavy, it is difficult to align the filter with the pipeline, so the removal and installation of the filter is time-consuming and laborious, resulting in reduced operating efficiency

Abstract

The invention provides an afterheat boiler which comprises a boiler body, a stream drum, a circulating pump and a filter device. The boiler body is provided with a heat exchanger; the stream drum comprises an outer shell which is respectively connected with a water supply pipe, a drainage pipe, a return pipe and a steam outlet pipe, wherein the drainage pipe and the return pipe are respectively connected with the heat exchanger; the circulating pump is arranged on the drainage pipe; the filter device is arranged on the drainage pipe and arranged between the circulating pump and the stream drum; the filter device comprises a filter body, a bracket and a supporting frame; the filter body is provided with an inlet, an outlet and a filter core arranged therein; and the bracket is mounted on the filter body and can be movably supported on the supporting frame along the longitudinal direction. The filter device of the afterheat boiler is rapid to dismount, replace and mount the filter core to improve the operation efficiency.

Description

technical field [0001] The invention relates to a waste heat boiler, in particular to a waste heat boiler with a filter device. Background technique [0002] Waste heat boilers are equipment for recovering heat. For example, in the field of non-ferrous metallurgy, waste heat boilers are widely used to recover heat from flue gas discharged from smelting furnaces. [0003] Traditionally, the waste heat boiler usually includes a furnace body, a steam drum and a circulation pipeline. The circulation pipeline supplies the cooling water in the steam drum to the furnace body, and the mixture of water and steam after heat exchange in the furnace body is returned to the steam drum, the steam is discharged through the steam drum for gas use, and the returned water is recycled. [0004] In order to avoid the adverse effects of cooling water on the furnace body, steam drum, circulating pipeline, circulating pump, etc., the waste heat boiler has relatively high requirements on cooling w...
