Problems solved by technology

Since the sludge is heated, a small part of it is coked, resulting in burnt odor with a very low threshold. The requirements for the deodorization system are extremely high, and oxygen oxidation is often required to

Abstract

The embodiment of the invention discloses a sludge drying machine energy-saving consumption-reducing and waste gas zero-emission system and method based on a zero-emission framework. The system includes: a sludge drying machine, a spiral discharging machine, a dust remover, a heat regenerator, a circulating fan, a heat exchanger, a cooling tower and a deodorization system, the sludge drying machine is used for drying the sludge to obtain a mixture of water vapor and air; the dust remover is used for removing dust from the mixture of the water vapor and the air; the heat regenerator is used forcooling the gas generated by the dust remover; the heat exchanger is used for carrying out heat exchange on cold water provided by the cooling tower and gas cooled by the heat regenerator; the deodorization system is used for deodorizing waste gas generated by the heat exchanger and then feeding the deodorized waste gas into the circulating fan through the heat regenerator, and the circulating fan is used for feeding the treated gas into the sludge drying machine. According to the scheme, zero emission of waste gas treatment is achieved, the operation cost is saved to the maximum extent by recycling heat energy, and compared with a traditional sludge drying deodorization process, the treatment scale is greatly reduced, the cost performance is high, and good economic benefits are achieved.

Description

technical field [0001] The embodiment of the present application relates to the field of environmental protection technology, and in particular to a system and method for energy saving and consumption reduction of sludge dryer and zero emission of exhaust gas based on a zero-emission architecture. Background technique [0002] With the acceleration of my country's urbanization process, people's living standards continue to improve, people's environmental awareness is constantly increasing, the requirements for the ecological environment are getting higher and higher, the pressure of traditional industrial environmental protection upgrading is increasing, and the corporate social responsibility is also increasing. stronger. [0003] The existing waste gas treatment methods of sludge dryers are mainly as follows: sludge enters the dryer through a sludge delivery pump, heat is obtained through a disc scraper heated by steam, and the water in the sludge is heated and gasified to ...
