Novel corrosion-resistant boiler for industrial sewage treatment

Abstract

The invention discloses a novel corrosion-resistant boiler for industrial sewage treatment, and belongs to the technical field of sewage treatment. The novel corrosion-resistant boiler comprises a boiler main body, a smoke exhaust pipe and an exhaust pipe are clamped and connected to the side surface of the boiler main body, and the end, close to the smoke exhaust pipe, of the exhaust pipe communicates with the end, close to a primary filtering tank, of the exhaust pipe through a three-way connecting pipe. According to the novel corrosion-resistant boiler, on one hand, through mutual cooperation of design of the primary filtering tank, an adapter shaft, a turbine, a spiral blade, a scraper blade, a filtering plate, a secondary filtering tank, a booster pump, a motor, a driven gear, a driving gear, a stirring shaft, an air hole, a bucket-shaped body, a ball valve, an elastic support device, a second support screen plate and other structures, the heat exchange efficiency of the boiler main body is ensured; and on the other hand, the secondary utilization rate of heat energy carried by high-pressure airflow can be realized, energy conservation and emission reduction effects are realized, descaling is performed by high-temperature airflow, damage of metal friction to a corrosion-resistant layer can be avoided, a thin structural layer can be dried, and the descaling effect is improved.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, in particular to a novel corrosion-resistant boiler used for industrial sewage treatment. Background technique [0002] The boiler is a kind of energy conversion equipment. The energy input to the boiler includes chemical energy and electric energy in the fuel. The boiler outputs steam, high-temperature water or organic heat carrier with a certain amount of heat energy. The original meaning of the pot refers to the water container heated on the fire. Furnace refers to the place where fuel is burned. The boiler includes two parts: the boiler and the furnace. The hot water or steam generated in the boiler can directly provide the required heat energy for industrial production and people's life, and can also be converted into mechanical energy through a steam power device, or regenerated. The generator converts mechanical energy into electrical energy, and the boiler that provides hot water...

Problems solved by technology

[0004] The purpose of the present invention is: in order to solve the problem that the selected corrosion-resistant boiler still has some deficiencies in the process of using, it is easy to produce a large amount of corrosive scaling, which affects the thermal conductivity of the boiler, and a large amount of heat energy is between the boiler and the scaling. In between, it is easy to cause damage to the corrosion-resistant layer, resulting in a reduction in the service life of the boiler. There are many harmful substances in the flue gas, which leads to high treatment costs. Even if the emission standards are met, there will still be a large amount of harmful substances to the human body. The proposed new corrosion-resistant boiler for industrial sewage treatment
