Smoke dust removing and waste heat recovering integrated box of boiler

Abstract

The invention relates to a smoke dust removing and waste heat recovering integrated box of a boiler. The smoke dust removing and waste heat recovering integrated box comprises a box body and a support connected to the bottom of the box body. An inner cavity of the box body is divided into a smoke cavity, a heat exchange cavity and a dust removing cavity by a front vertical partition board and a rear vertical partition board. A first horizontal partition board dividing the smoke cavity into a smoke inlet cavity and a smoke outlet cavity is arranged in the smoke cavity, and a second horizontal partition board dividing the dust removing cavity into an upper dust cavity and a lower dust cavity is arranged in the dust removing cavity. A plurality of heat exchange pipes are arranged in the heat exchange cavity at intervals, part of the heat exchange pipes are communicated with the smoke inlet cavity and the lower dust cavity, and the other part of the heat exchange pipes are communicated with the upper dust cavity and the smoke outlet cavity. A smoke inlet is formed in the smoke inlet cavity, and a smoke outlet is formed in the smoke outlet cavity. The upper portion and the lower portion of the heat exchange cavity are provided with an air outlet and an air inlet respectively, and a cyclone dust removing pipe is arranged on the second horizontal partition board. The smoke dust removing and waste heat recovering integrated box of the boiler has the advantages of being simple in structure, convenient to use and capable of recycling smoke heat and removing dust of smoke.

Description

technical field [0001] The invention relates to a boiler flue gas dust removal and waste heat recovery integrated box. Background technique [0002] Boilers are widely used in production and life. The flue gas of existing boilers, especially small and medium-sized boilers, is mostly discharged directly into the atmosphere, and the dust and sulfur oxides in the flue gas will cause serious pollution to the environment. In addition, the flue gas also carries a large amount of heat, which leads to energy loss and lower fuel utilization, which not only pollutes the environment but also increases production costs. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a boiler flue gas dedusting and waste heat recovery integrated box which is simple in structure, easy to use, capable of recycling flue gas heat and dedusting flue gas. [0004] In order to solve the above-mentioned technical problems, the boiler flue gas dust...

Problems solved by technology

The flue gas of existing boilers, especially small and medium-sized boilers, is mostly discharged directly into the atmosphere, and the dust and sulfur oxides in the flue gas will cause serious pollution to the environment

In addition, the flue gas also carries a large amount of heat, resulting in energy loss and reduced fuel utilization, which not only pollutes the environment but also increases production costs.
