Embodiment Construction

[0030] The present invention will be described in further detail below in conjunction with the embodiments of the drawings.

[0031] As shown in Figure 1, the system equipment mainly includes an incinerator 10, a dry sludge silo 6, a wet sludge silo 8, and a sludge pump 9, a metal heat exchanger 1, a metal regulator 2, a dryer 3, The separator 4, the metal conveyor 5, the exhaust gas processor 7 and the flue gas treatment system 11 are. among them

[0032] The structure of the metal heat exchanger 1 is shown in Figure 3. It has a drain-shaped shell 1 with a metal inlet 102 and a metal outlet 103 on the top and bottom of the shell, respectively. A flue gas outlet 105 and a flue gas inlet 104 are respectively provided on the side. The flue gas inlet 104 is connected to the incinerator 10 through a pipe, and the flue gas outlet 105 is connected to the flue gas processing system 11. The granular metal for heat transfer uses steel balls, which are added from the inlet 102 at the top of...

Abstract

The invention discloses a drying method by using a metal object as a heat transfer medium and a system device thereof. The method and the device adopt the granular metal object as the heat transfer medium, make the metal object accept heat of a heat source through a heat exchanger, allow the metal object with certain temperature and mud to be directly contacted and mixed in a drier, and transfer heat of the metal object to the mud by a transmission method, thereby achieving the aim of intensifying heat transfer, heating the mud and evaporating moisture in the mud. The device has the advantages of simple and reliable system, strong controllability, good adaptability to multiple kinds of mud, requirement fulfillment to different specifications, small occupied area, low investment, high heat efficiency and the like, solves the technical problems of difficult tail gas treatment, high energy consumption and the like in the direct convection type drying technology by using flue gas or hot air as the heat transfer medium, and avoids the defects of complicated equipment, high cost, small capacity of single equipment, easy wall adhesion and the like in the indirect conduction type drying technology by using vapor or conduction oil as the heat transfer medium. The method and the device can be used for drying mud and other wet materials, household garbage and other waste materials.

Description

Technical field [0001] The invention relates to a waste treatment technology, in particular to a waste drying method and its system device using metal as a heat transfer medium, which is suitable for drying wet materials such as sludge, and also suitable for domestic and industrial waste And other waste pretreatment drying and crushing. Background technique [0002] With the continuous improvement of my country’s requirements for water environmental protection, a large number of sewage treatment facilities have been constructed and put into operation, accompanied by a large amount of high-moisture (70%-85%) sludge. If these sludge cannot be timely, effectively and Stable treatment and disposal will bring great environmental hazards to surrounding areas. [0003] Regardless of whether the sludge treatment is incineration, agricultural use or as a raw material for building materials, choosing a suitable drying process is the key to reducing investment and operating costs. In the ex...
