Novel spray type desulphurization dust removal boiler

Abstract

The invention relates to a novel spray type desulphurization dust removal boiler. A round smoke chamber is rolled by using a plate rolling machine; The upper part and the lower part of the boiler are welded with plugging covers and are provided with two flanges; the upper flange is connected with a chimney, and the lower flange is connected with the upper flange of the boiler; a water inlet pipe is connected with a water pump; water from a spray header is input into a spray chamber to be mixed with a flue gas; because the mixture of the water and the flue gas has a certain weight, the mixture falls into a sedimentation tank after flowing out of a sewage pipe and is purified in the sedimentation tank, then flows into a sewage tank and flows out of the sewage tank through a sewage discharge pipe. The sewage tank and the smoke chamber are positioned by round bars with the same length to ensure that the sewage tank is concentric with the spray chamber, and the underside of the sewage tank is supported by a round bar to ensure that a spray type desulphurization dust remover of a vertical boiler is stable. The spray chamber and the sewage tank use acid-proof cement layers for protection. The lower flange is connected with an upper flange of the chimney of the boiler, and a manhole is used for clearing fouling of a spray head. In production, a welded part should be noted not to leak smoke so as to achieve an effective dust removal and desulfurization effect.

Description

technical field [0001] The invention relates to a dust-removing boiler, in particular to a novel spray-type desulfurization and dust-removing boiler. It belongs to the technical field of boiler manufacturing. Background technique [0002] At present, there are a large number of coal-fired vertical boilers used in the country, and they are basically used by self-employed individuals. The desulfurization and dust collectors on the market are suitable for boilers above 2T / h, but the dust removal of small vertical boilers is basically blank. Because there is no effective desulfurization and dust removal mechanism, the small vertical boiler has large resistance, poor natural ventilation, large investment, complicated installation, high smoke and sulfur dioxide, and large pollution. Contents of the invention [0003] The purpose of this invention is to provide a new type of spray desulfurization and dust removal boiler with low pressure, good natural ventilation, low investmen...

AI Technical Summary

Problems solved by technology

Due to the lack of effective desulfurization and dust removal mechanism, small vertical boilers have large resistance, poor natural ventilation, large investment, complicated installation, a lot of smoke and sulfur dioxide, and heavy pollution.
