Abstract
Description
TECHNICAL FIELD

[0002] In the field of high-concentration high-salt wastewater treatment, the current common pretreatment processes include coagulation sedimentation and advanced oxidation, and the sludge generated by the processes is hazardous waste. After being treated by a filter press, the moisture content of the sludge is still about 80%, and the sludge is generally directly disposed by a hazardous waste treatment institution. If the moisture content of the sludge can be reduced to below 60%, the treatment cost can be effectively reduced. However, the high salt ion concentration in the high-concentration high-salt wastewater makes the moisture content requirement of the sludge generated by the physicochemical pretreatment process more stringent. In the prior art, in order to achieve a lower moisture content, a more complex operation process and a dosing program need to be used in the material selection of the filter press, which not only increases the treatment cost and operation difficulty, but also causes the total amount of dry sludge to increase, further increasing the burden of subsequent treatment.

Those skilled in the art should understand that this application can be implemented without certain specific details. In some instances, methods, means, components, and circuits well-known to those skilled in the art have not been described in detail in order to highlight the main points of this application.
[0035] like Figs. 1-3 As shown, the high-concentration, high-salt wastewater sludge reduction device of this application embodiment includes: a shell 100, a first motor 300, and a first spiral blade 210. The shell 100 is a hollow sandwich structure 110 with a sludge inlet 120 at the top and a sludge outlet 130 at the bottom. The shell 100 also has a heat source outlet 150 and a heat source inlet 140, which are connected to the interior of the sandwich structure 110. The first spiral blade 210 is disposed inside the shell 100, and its two ends are rotatably connected to the left and right sides of the shell 100, respectively. The first motor 300 is disposed outside the shell 100, and the output shaft of the first motor 300 is fixedly connected to the first spiral blade 210, driving the first spiral blade 210 to rotate.
[0036] In this embodiment, the combined effect of the heat source jacket, the self-heating of the spiral blades, and the induced draft device 170 effectively reduces the moisture content of the sludge, lowering the moisture content of the high-concentration, high-salt wastewater sludge to a low level and reducing subsequent treatment costs. Specifically, the rotation of the spiral blades driven by the motor agitates and transports the sludge, ensuring it is in full contact with the heat source within the shell 100, promoting moisture evaporation and providing power support for subsequent reduction of sludge moisture content.
[0037] In one specific embodiment, one end of the first spiral blade 210 is the feed end and the other end is the discharge end. The feed end of the first spiral blade 210 corresponds vertically to the sludge inlet 120, which can ensure that the sludge enters the conveying path of the spiral blade smoothly, avoid the accumulation and blockage of sludge when entering the device, and ensure the continuous and stable operation of the device.
[0038] The first spiral blade 210 includes a connecting rod 211 and a blade 222. The blade 222 is spirally arranged on the connecting rod 211 and along the length of the connecting rod 211 to form a conveying path, which can dehydrate and convey the waste material along the length of the connecting rod 211 to the other end.
[0039] In one specific embodiment, the clamping structure of the housing 100 is provided with a heat source inside, which provides heat for the drying of sludge, improves the water evaporation efficiency, and can more effectively reduce the water content of sludge compared with traditional treatment methods.
[0040] In one specific embodiment, the first spiral blade 210 is a sandwich structure 110, which is filled with hot oil or steam to increase the heat exchange area and heat exchange efficiency with the sludge, so that the sludge can be heated more quickly and fully, accelerate the evaporation rate of water, and improve the efficiency of sludge dewatering.
[0041] In one specific embodiment, an air inlet 160 is provided at the top of the housing 100, and an air intake device 170 is provided inside the air inlet 160. The air intake device 170 accelerates the discharge of water from the sludge, prevents water vapor from accumulating inside the housing 100 and affecting the water evaporation efficiency, and further improves the treatment effect and efficiency of sludge reduction.
[0042] Among them, the air-drawing device 170 can be a device that draws air into the housing 100, which will not be described in detail here.
[0043] In one specific embodiment, it further includes: a second helical blade 220 and a second electrode. The second helical blade 220 is disposed inside the housing 100, and its two ends are rotatably connected to the left and right sides of the housing 100 respectively. The second motor 500 is disposed outside the housing 100, and the output shaft of the second motor 500 is fixedly connected to the second helical blade 220 to drive the first helical blade 210 to rotate. The first helical blade 210 and the second helical blade 220 are arranged vertically, and the first helical blade 210 is located above the second helical blade 220.
[0044] Furthermore, the structure of the second helical blade 220 is the same as that of the first helical blade 210. The first helical blade 210 and the second helical blade 220 of the two-stage helical blades can extend the treatment path and treatment time of sludge in the device, so that the sludge can be more fully stirred, heated and dewatered, further reducing the sludge moisture content and improving the degree of sludge reduction.
[0045] In one specific embodiment, the feed end of the second helical blade 220 corresponds vertically to the discharge end of the first helical blade 210, and the discharge end of the second helical blade 220 corresponds vertically to the sludge outlet 130 of the housing 100. This arrangement ensures that the sludge can be discharged and collected from the sludge outlet 130 after dewatering.
[0046] In one specific embodiment, the device further includes a partition 400, which is a plate-shaped structure vertically disposed inside the housing 100, separating the interior of the housing 100 into a dehydration space and an exhaust space. The partition 400 has multiple ventilation holes 410 connecting the dehydration space and the exhaust space within the housing 100, with the exhaust space corresponding to the ventilation holes. The partition 400 with ventilation holes 410 divides the interior of the housing 100 into two parts. The first helical blade 210 and the second helical blade 220 are disposed within the dehydration space. Since the exhaust space is connected to the ventilation holes, water vapor can be discharged more systematically, improving dehydration efficiency. It also helps maintain the uniformity of temperature and humidity inside the device, ensuring the stability of the sludge treatment effect.
[0047] In one specific embodiment, the vent 410 includes a first vent 410 group and a second vent 410 group. The first vent 410 group includes multiple vents 410 arranged in an array, located on the top of the partition 400, and corresponding to the upper part of the first spiral blade 210. The second vent 410 group includes multiple vents 410 arranged in an array, located in the middle of the partition 400, and corresponding to the upper part of the second spiral blade 220. The placement of the first and second vent 410 groups ensures that water vapor evaporating at different locations can be discharged in a timely manner, preventing water vapor accumulation from affecting the sludge drying effect and improving the dewatering performance of the entire device.
[0048] The various embodiments of this application have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments. The terminology used herein is chosen to best explain the principles, practical application, or improvement of the technology in the market, or to enable others skilled in the art to understand the embodiments disclosed herein.
