Description

Technical Field

[0001] The utility model relates to the field of waste heat boilers, in particular to a dust removal waste heat boiler. Background Technique

[0002] A waste heat boiler refers to a boiler that uses the waste heat in various industrial processes, waste materials or waste liquids, and the heat generated after the combustion of combustible substances therein to heat water to a certain working medium. Through the waste heat boiler, the waste gas or waste can be reused, which can greatly improve the utilization rate of heat and achieve the purpose of energy conservation and environmental protection.

[0003] At present, after the waste heat boiler utilizes the waste heat of the flue gas, the flue gas will be discharged. However, the flue gas discharged by the current waste heat boiler still contains a large amount of dust, which is easy to pollute the air environment and cannot achieve the effect of environmental protection production. Therefore, we propose a dust removal waste heat boiler to solve the above problems. Content of the Utility Model

[0004] The purpose of the utility model is to provide a dust removal waste heat boiler to solve the problems put forward in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0011] In a further embodiment, a flue gas flange is fixedly communicated with one end of the waste heat pipe far away from the housing, and a warning sign is fixedly connected to the front surface of the housing.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] Through the arrangement of the housing and the heat exchanger, the high-temperature flue gas can flow between the housing and the heat exchanger, which will heat the fluid inside the heat exchanger by the high-temperature flue gas, and then achieve the effect of utilizing the waste heat of the flue gas. Through the provided spray tank and spray tray, and in cooperation with the connecting pipe, the flue gas can be discharged into the spray tank through the connecting pipe, and the dust in the flue gas will be sprayed and dust-removed. At the same time, in cooperation with the filter plate inside the filter cover, the dust can be adsorbed again, and then the waste heat boiler can achieve the effect of dust removal when the flue gas is discharged, avoiding polluting the air environment.
