Description

technical field [0001] The invention relates to the field of sewage treatment and the field of heat pump heat exchange, in particular to a heat pump type closed sludge drying system. Background technique [0002] With the emphasis on sewage treatment, the main market of sewage treatment in my country is basically completed. In the plan, the sewage treatment market will be further promoted and expanded, and the efficiency of sewage treatment and the average technical level of the industry will be improved. As a derivative of sewage, the output of sludge has also been increasing in recent years. In 2015, the output of domestic sludge reached 35 million tons, a year-on-year increase of 16%. It is estimated that about 10,000 tons of sewage will produce 50,000-80,000 tons of sludge in terms of municipal sludge. According to estimates by experts, my country produces 30 million to 40 million tons of municipal sludge with a water content of about 80% every year. The amount of slud...
