Embodiment Construction

[0015] see figure 1 with figure 2 , the present invention includes a mobile shelter 14 mounted on a truck. The mobile shelter 14 is divided into two parts, front and rear, and its rear part forms a closed cabin for an airtight structure. A sludge extraction unit 11 , a cleaning tank 6 , a dehydration unit 9 , a delivery unit 10 , a dosing unit 13 , and a sealed packaging unit 12 are installed in the airtight cabin on the mobile shelter 14 . Also comprise the purification ventilating unit that is made up of centrifugal fan 15 and air filter 16, the control display unit that is made up of micro pressure sensor, display instrument, power inverter, control panel, switch one and alarm and is made up of ultraviolet lamp 18 and switch Two-component disinfection unit. Generator 1 and its electric control cabinet one 2 and electric control cabinet two 3 are installed on the upper front of the mobile shelter 14. The generator 1 supplies power to each unit and is controlled by the el...

Description

technical field [0001] The invention relates to the field of environmental protection, in particular to negative pressure mobile sludge drying treatment equipment. Background technique [0002] The drying treatment of the sludge can significantly reduce the volume of the sludge, and the volume can be compressed to 1 / 4-1 / 5 of the original. The sludge product after drying is stable, odorless, and pathogen-free, and can be used as fertilizer, soil improver, etc., or as an alternative energy source. As early as the 1940s, Japan, Europe and the United States have used direct heating drum dryers to dry sludge. After decades of development, the advantages of sludge drying technology are gradually emerging. Due to the high requirements for sludge thermal drying technology, high processing costs and complicated management, this technology was not promoted in western developed countries until the successful application in Sweden and other countries in the late 1980s. [0003] At pre...
