Problems solved by technology

At the same time, the total amount of sewage discharge in most cities is also in a trend of continuous and rapid increase. However, at the same time, the corresponding sewage treatment rate has not increased correspondingly, resulting in the discharge and storage of sludge has become a new major source of pollution.

Embodiment Construction

[0040] like Figure 1 to Figure 5 Shown is a sludge heating and drying system of the present invention, including a pretreatment mechanism, a transmission mechanism and a drying mechanism. The pretreatment mechanism is connected to the drying mechanism through the transmission mechanism. The pretreatment mechanism includes a dehydration chamber 1 and a dispersion chamber 2. Chamber 1 and dispersing chamber 2 are arranged in sequence from left to right.

[0041] The dehydration chamber 1 is provided with a dehydration cylinder 3 and an extruding device, the extruding device is arranged in the dehydration cylinder 3, and the lower side wall of the dehydration cylinder 3 is uniformly provided with water leakage holes 15, and the water leakage holes 15 are all provided with water-permeable membranes. The left end of the cylinder 3 is provided with a left seal ring, and the feed hopper 36 extends into the dehydration cylinder 3 through the left seal ring. The design can facilitate...

Abstract

The invention discloses a sludge heating and drying system, which includes a pretreatment mechanism, a transmission mechanism and a drying mechanism. The pretreatment mechanism includes a dehydration chamber and a dispersion chamber. An inclined table and a dispersing device, the drying mechanism includes a drying box and a heating device, and the drying method includes the following steps: (1) sludge initial water removal treatment; (2) sludge dispersion treatment; (3) sludge drying treatment; (4) Cleaning and inspection and repair. The invention has simple structure and strong practicability. Most of the sewage in the sludge is removed through the dewatering chamber, and then the extruded sludge is dispersed through the dispersion chamber, so as to reduce the working pressure of the drying box and improve the sludge yield. The drying effect and drying quality are improved, water resources are saved, and the comprehensive utilization rate is improved.

Description

technical field [0001] The invention relates to a sludge heating and drying system and a method thereof. Background technique [0002] The process of urbanization in our country is in the stage of accelerating, and the situation of environmental pollution is also increasing. The sludge problem has become a major problem related to people's life. The annual sludge output in our country is very huge, and the weight is very alarming. At the same time, the total amount of sewage discharge in most cities is also in a trend of continuous and rapid increase. However, at the same time, the corresponding sewage treatment rate has not increased correspondingly, resulting in sludge discharge and stacking has become a new major pollution source. For the increasingly large amount of sludge, it has become the focus of our country's staff to take effective measures to dehydrate these huge amounts of sludge, so that it can achieve the goals of being environmentally friendly, reducing the a...
