Hot cleaning furnace with dual purification treatment

Abstract

The invention discloses a hot cleaning furnace with dual purification treatment. The hot cleaning furnace comprises a furnace body, wherein a first combustion chamber is arranged at the bottom of the furnace body and a second combustion chamber with a smoke exhausting opening is arranged at the top of the furnace body; each of the inner part of the furnace body and the inner part of the second combustion chamber is provided with a temperature sensor; the smoke exhausting opening is provided with a waste gas purification device; the furnace body is provided with a spraying system; the spraying system comprises a spraying pipe, a circulating water groove and a water tank; the water tank is internally provided with a water level monitor. The hot cleaning furnace with the dual purification treatment is reasonable in structure design; the waste gas purification device is arranged and is used for carrying out purification treatment on high-temperature gas; an atomization high-pressure nozzle is used for washing suspended particles in the gas and a baffle is used for increasing a gas flowing route so that gas and solids, which have different specific gravities, can be separated in the route; the secondary purification treatment of the waste gas is realized and the environmental pollution is reduced; the first combustion chamber with an arch-shaped structure is arranged so that the rapid rising of the temperature in the furnace is realized, so that the treatment time is shortened and the energy consumption is saved; an electric cabinet is arranged so that automatic work is convenient to realize and the operation is easy.

Description

technical field [0001] The invention relates to a heat-cleaning furnace, in particular to a heat-cleaning furnace with double purification treatment. Background technique [0002] Hot cleaning furnace, also known as paint stripping furnace, carbonization furnace, incineration furnace, has been widely used in air conditioners, refrigerators, microwave ovens, electric fans, computers, spraying and other home appliance industries as well as motorcycles, bicycles, automobiles, steel furniture, communications, metal industries such as recycling. In the prior art, the coating peeling treatment methods: one is that people traditionally use incineration and chemical methods, which are costly, toxic, cause harm to the operator, cause large deformation of the workpiece, and cause environmental pollution and other problems; the other The method of thermal decomposition is used to deal with the coating peeling. The coating peeling devices that adopt thermal decomposition in the market ...

Problems solved by technology

In the prior art, the coating peeling treatment methods: one is that people traditionally use incineration and chemical methods, which are costly, toxic, cause harm to the operator, cause large deformation of the workpiece, and cause environmental pollution and other problems; the other The method of thermal decomposition is used to deal with the coating peeling. The coating peeling devices that adopt thermal decomposition in the market all use the main and auxiliary burners to heat and treat the exhaust gas respectively. This kind of structure usually has the following problems: First, The combustion in the main drying chamber is uneven, and the temperature in the furnace is slow to rise. At the same time, the temperature in the furnace is difficult to reach a consistent temperature in a short period of time, and the processing time is long; , the flue gas is directly discharged, which is likely to be critical to the national standard, causing air pollution; the third is to use temperature sensors, temperature control meters and time relays to control the work of the burner, usually when the amount of organic matter is small, The preset time is often too long, resulting in waste of energy. When the amount of organic matter is large, the preset time is often too short. The workpiece in the furnace has not been processed, but the hot cleaning furnace has stopped working, causing smoke in the chimney, which needs to be reprocessed, and pollutes the environment. ,low efficiency
