Description

Gas heating for commercial scrubbers

technical field

The utility model relates to the technical field of gas heating devices, in particular to a gas heating device for commercial cleaning equipment.

Background technique

According to the country's emphasis on environmental pollution in recent years, especially the traditional coal-fired heating production industry has been seriously affected. After coal is restricted as a relatively cheap energy source, the remaining energy is nothing more than electricity and gas, which attract people's attention and are expensive. High electricity prices and tight supply-demand relations simply cannot meet the needs of the industry. Compared with electric heating systems, the use of gaseous fuels can significantly reduce energy costs; compared with coal-fired heating systems, it is basically pollution-free and unlimited in use. Based on the above advantages, Gas is often the first choice in the heating industry, and gas heating is also used in the field of cleaning equipment.

Cleaning equipment refers to automatic equipment that can be used to replace manual cleaning of various workpieces and articles. Cleaning equipment is usually suitable for commercial purposes and has the characteristics of high temperature, disinfection, high intensity, and short time processing.
