Embodiment Construction

[0008] The present invention will be further described below in conjunction with accompanying drawing:

[0009] As shown in the accompanying drawings, the sludge drying and carbonization treatment device includes a drying treatment device and a carbonization treatment device. 4. Composed of pump 5, combustion furnace 6, fuel tank 7, cooling tower 8, rotary kiln 9, secondary dryer 10 and dry matter storage tank 11, the sludge stored in the hopper 1 enters from the outlet through the screw conveyor 2 The first drying is carried out in the first stage dryer 3, and the sludge after the first drying enters the rotary kiln 9 through the screw conveyor 2, and the sludge is reheated in the combustion furnace again, and then returned to the first stage dryer 3, indirect heating is carried out to achieve the purpose of making full use of waste heat resources. The sludge heated by the rotary kiln 9 is fed into the secondary dryer 10 through the screw conveyor 2 for secondary drying, and...

Abstract

The invention relates to a sludge drying and carbonizing processing device which mainly solves the problems that the prior sludge processing device has high processing cost, needs huge amount of auxiliary fuel and has poor processing effect. The sludge drying carbonization processing device is characterized by comprising a drying processing device and a carbonizing processing device, wherein the drying processing device comprises a charge hopper (1), a screw rod transmission machine (2), a primary drier (3), a fan (4), a pump (5), a combustion furnace (6), a fuel tank (7), a cooling tower (8),a rotary furnace (9), a secondary drier (10) and a drying object storage tank (11); and the carbonizing processing device comprises a fire spray type carbonizing machine combustion furnace (11), a carbonizing machine (12), a carbonized object storage tank (13) and a condenser. The sludge drying carbonizing processing device has the characteristics of low processing cost, less auxiliary fuel and favorable processing effect, thereby achieving the effects of energy saving and environmental protection.

Description

Technical field: [0001] The invention relates to a sludge treatment device, in particular to a sludge drying and carbonization treatment device. Background technique: [0002] As the urban population continues to grow, so does the amount of sludge generated. Sludge is composed of sediment left over from the sewage treatment process and has a high moisture and organic content, so it is very difficult to deal with. To deal with this kind of activated sludge, it needs to be stabilized first, then dehydrated, and finally disposed of in the following ways. There are many types of sludge disposal technologies, but landfill and incineration have always been the main methods. Although the disposal cost of landfill is not high, the methane (greenhouse effect) and leached water (odor) produced by landfill will cause environmental pollution, and the expansion of landfill is also restricted by many factors, which will make land use more efficient decline. Another commonly used techn...
