Problems solved by technology

This process has the following problems: when the sludge just enters the drying cylinder, the moisture content is very large, and at this time it should be the point with the largest evaporation and the highest drying efficiency. Dense hard shell, low diffusion contact between sludge and hot air, low evaporation efficiency
Since two machines are used for granulation and mixing, the production cost is relatively high and the production efficiency is relatively low

Abstract

The invention relates to a production line and a preparation method of sludge and straw mixed fuel. The production line comprises a sludge belt conveyer, a straw grinding machine, a straw pneumatic conveyer and a sludge and straw granulating and drying integrated machine, wherein the sludge and straw granulating and drying integrated machine comprises a sleeve, a granulator, a reduction box, a motor, a screw rod shaft system, a bearing and a microwave generator; the sludge bucket granulator communicated with the sleeve is arranged at the upper end of the sleeve and used for dividing the sleeve into a conveying region and a drying region; the screw rod shaft system penetrates through the granulator; the bearing is arranged between the screw rod shaft system and the granulator; a conveying spiral blade is arranged at a part of the screw rod shaft system, arranged in the conveying region; a stirring blade is arranged at a part of the screw rod shaft system, arranged in the drying region; the microwave generator, a gas outlet and a straw inlet are arranged on the side wall of the sleeve, arranged below the granulator. The sludge conveying process, the sludge granulating process, the straw grinding process and the sludge and straw mixing process are integrated on the production line and synchronously conducted, so that the production efficiency is improved and the automation level is increased.

Description

technical field [0001] The invention relates to the field of sludge and straw mixed fuel, in particular to a production line of sludge and straw mixed fuel and a preparation method thereof. Background technique [0002] With the rapid advancement of urbanization in my country, the amount of municipal sludge is increasing. According to statistics, the total annual sludge production in the country will soon exceed 30 million tons. Due to the large number of urban industrial parks, domestic sewage treatment plants often mix industrial wastewater, resulting in high heavy metal content in sludge. At present, landfill is the main treatment method for sludge in China, and the utilization rate of resource energy is low. Studies have shown that the ignition and burnout characteristics of sludge are good. The reduction of incineration is obvious, and it is one of the directions of sludge treatment in the world. But the calorific value of sludge itself is low, about 1500kcal / kg. I...
