Embodiment Construction

[0022] like figure 1 and figure 2 As shown, the sludge integrated treatment device of the present invention includes a drying part and a carbonization part. A first mud inlet 11 and a first air inlet 12 are processed on the top of the drying part containing the drying box 1, and a first mud outlet 16 and a first air outlet 15 are respectively processed on the bottom of the drying box 1 and on one side of the box bottom. . A heat collector is arranged above the drying box 1. The heat collector contains a box body 7 and a heat pump 8. The box body 7 is a closed box body. The inner side of the box bottom and the inner side of the four walls of the box body 7 are made of foam insulation materials For the insulation layer, the top plate of the box body 7 is made of light-transmitting glass, and the cold end of the heat pump 8 is placed in the box body 7 . In this way, in the daytime and when the sun is shining, the solar energy can be fully utilized to heat the cold end of the ...

Abstract

The invention relates to an integrated sludge treatment device which is characterized by comprising a drying part and a carbonizing part. The drying part comprises a drying box, wherein the drying box is provided with a first sludge inlet, a first air inlet, a first sludge outlet and a first air outlet. The drying box is internally provided with at least two belt conveyors and the belt conveyors are arranged up and down; and the rotation directions of the adjacent belt conveyors are opposite and the belt conveyors are crossly arranged in a staggered manner. The carbonizing part comprises a carbonizing furnace; the furnace body of the carbonizing furnace is internally provided with upper and lower sludge grooves; and the upper and lower sludge grooves are internally provided with agitators. A combustor is arranged between the upper and lower sludge grooves. A second sludge inlet and a second air outlet are arranged at the top of the furnace body; a second conveyor is arranged below the sludge outlet of the drying box and an inlet of the second conveyor is communicated with the sludge outlet of the drying box; and the sludge outlet of the second conveyor is communicated with an inlet of a third conveyor. With the adoption of the integrated sludge treatment device, the sludge treatment cost can be reduced, and the pollution to the environment can be completely avoided. The integrated sludge treatment device is applicable to the treatment on sludge in middle-sized and small-sized sewage treatment plants.

Description

technical field [0001] The invention relates to a sludge treatment equipment. Specifically, it is an integrated treatment device for drying and carbonizing sludge. It is suitable for sludge treatment in small and medium-sized sewage treatment plants. Background technique [0002] With the acceleration of urbanization, the amount of sewage produced increases year by year. In order to reduce the pollution of sewage to the environment, the state and enterprises have invested a lot of financial resources and established many sewage treatment plants to purify urban sewage. The sewage treatment plant will produce a large amount of sludge in the process of sewage treatment. Sludge is the product of the accumulation of many pollutants. If the sludge is not treated, it will bring secondary pollution to the environment. Therefore, the sludge produced by the sewage treatment plant must be treated. [0003] At present, the treatment of sewage sludge mainly includes the following tw...
