Description

Technical Field

[0001] The invention relates to the field of sewage treatment, in particular to sludge drying treatment equipment for sewage treatment. Background Art

[0002] Sludge is the terminal product of sewage treatment. After biochemical treatment of sewage, a large amount of residual sludge will be produced. There are a large number of bacteria in these sludges. If they cannot be treated in time, they will pose a huge threat to human health and the ecological environment. Due to the high water content of sludge, it is usually necessary to dry and dehydrate it first, reduce the weight of the sludge, and then conduct centralized harmless treatment. With the acceleration of industrial development and urbanization, industrial sludge and urban domestic sludge are increasing rapidly. The main drying modes currently used are: traditional thermal sludge drying and solar sludge drying. Traditional thermal sludge drying refers to the use of sludge thermal drying integrated equipment to dry sludge. According to the contact mode between the heat medium and the sludge, the drying equipment can be divided into direct drying, indirect drying and direct-indirect combined drying and other process types. The disadvantages of this type of equipment are high consumption and high cost, so the market application value is low. Another common method: solar sludge drying treatment.

[0003] Solar sludge drying technology is a common sludge drying method. It reduces the water content of sludge, eliminates sludge odor and pathogens, and increases the calorific value of sludge through sunlight irradiation. It is a sludge drying technology with low investment and low operating cost, which can reduce sludge, make it harmless, and recycle it.

[0004] Existing sludge solar drying devices are all set in solar drying sheds to enhance the photothermal effect. Sludge solar drying devices generally use a turning machine to continuously and comprehensively turn over the wet sludge spread in the drying area, so that the wet sludge is fully exposed to sunlight. After a period of time, the water in the wet sludge can be evaporated to achieve the drying effect. However, when treating sewage, it is very troublesome to use solar energy to convert high-concentration mud into sludge. After the wastewater is evaporated, the water vapor is not easy to leave, which easily causes high humidity in the entire space. In addition, the existing technology for converting high-concentration sewage into mud still requires auxiliary heating, which has high energy consumption and low efficiency.

[0005] Moreover, solar energy drying is prone to heat pipe blockage and is difficult to clean:

[0006] For example, patent CN216273706U discloses a sludge drying device. The sludge drying device includes a sludge drying chamber and a solar air collector. The sludge drying chamber is provided with a wet mud inlet and a PC solar panel. The solar air collector is connected to the interior of the sludge drying chamber through the wet mud inlet, and the high-temperature air heated by the solar air collector enters the interior of the sludge drying chamber through the wet mud inlet.

[0007] When the above-mentioned sludge drying device is in use, for the treatment of the dried sludge in the sludge drying device, the steps are to first open the PC solar panel at the top of the drying chamber, and then the personnel take it out by themselves using tools. However, no matter how high the sludge drying device is, it is inconvenient to rely solely on manual removal of the dry sludge from the top of the device, not to mention the cleanliness of the removal of the dry sludge, which wastes time and easily causes dry sludge residue inside the device. Summary of the invention

The bottom end of the inner mesh pipe is fixedly installed with a communicating elbow A above the extrusion ring. The other end of the elbow A runs through the heat pipe. The lower end of the heat pipe is fixedly installed with a transverse pipe connected to the annular cavity below the extrusion ring.

[0012] The ball valve is located in the bottom box and is opened and closed by the control assembly;

[0013] The outer end of the elbow A is connected to the connecting pipe B, and the outer end of the horizontal pipe is connected to the connecting pipe C.

[0014] Preferably, the solar drying component further comprises two temperature storage covers, which are respectively located on both sides of the heat pipe. The temperature storage covers are arc-shaped structures, and two ends thereof are respectively fixed to two fixing plates.

[0016] Preferably, the control component includes an electric push rod, a pull rod and a turntable. The pull rod is located in a base box. Both ends of the pull rod adopt rocker arms for being supported and rotated by the base box. One end of the electric push rod is hinged to the side wall of the base box, and the other end is hinged to one end of the pull rod. The number and position of the turntables correspond to the solar drying component. The turntables are mounted on the pull rod and rotatably connected to the pull rod.

[0022] The sludge drying treatment equipment for sewage treatment is provided with a solar drying component, a primary treatment box and a secondary treatment box. The wastewater in the primary treatment box can be pumped into a plurality of heat pipes. Since the annular cavity at the bottom of the heat pipe has a smaller diameter, the evaporation efficiency is higher, and the heat will rise, so the larger annular cavity at the upper end will be preheated and evaporated first, and the annular cavity at the bottom will focus on the precipitated sludge. Excess water in the wastewater will enter the inner network pipe, and the evaporated steam will also be pushed into the inner network pipe, and then recirculated to the primary treatment box for further precipitation treatment. The wastewater that has become sludge will not be discharged directly, but will be sent to the secondary treatment box for further precipitation, and then pumped back into the heat pipe, and then returned to the heat pipe for the first treatment, and the less viscous sludge in the heat pipe will be squeezed out and replaced with viscous sludge, which will be discharged through the ball valve after one cycle. In this way, when converting mud into sludge, solar energy circulation conversion can be utilized, and the circulation treatment has low energy consumption and good drying effect.

[0023] The sludge drying treatment equipment for sewage treatment is provided with a plurality of sets of solar drying components distributed in parallel. When the primary treatment box and the secondary treatment box are cyclically dried, the heat of the heat pipes treating the sludge with less water content will be higher than that of the heat pipes treating the sludge with more water content. Therefore, when the heat pipes of the two circulate alternately, the heat of the solar energy can be utilized to the maximum extent, and the heat can be maintained, so that the temperature change curve of the heat pipe fluctuates less during the circulation.

[0024] The sludge drying equipment for sewage treatment is equipped with a spiral pumping component. When pumping the sludge, it can squeeze out the sludge with less water content in the original heat pipe and press the water into the inner network pipe. The sludge is also discharged from the heat pipe smoothly, and the inside of the heat pipe can always be kept clean during circulation. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] like Figure 1-10 As shown, a sludge drying treatment equipment for sewage treatment includes a primary treatment box 1 and a secondary treatment box 2, one side of the primary treatment box 1 and the secondary treatment box 2 is provided with a spiral pumping assembly 3, the input ends of the two spiral pumping assemblies 3 are respectively connected to the bottom of the primary treatment box 1 and the secondary treatment box 2, and also includes a connecting pipe A4, a connecting pipe B5 and a connecting pipe C6, the output ends of the two spiral pumping assemblies 3 are respectively connected to the two ends of the connecting pipe A4; one end of the connecting pipe B5 is fixed and communicated with the upper end of the primary treatment box 1, and the other end is sealed, and one end of the connecting pipe C6 is fixed and communicated with the upper end of the secondary treatment box 2, and the other end is sealed;

[0041] It also includes two fixing plates 7 and a plurality of solar drying components 8, wherein the plurality of solar drying components 8 are located between the two fixing plates 7, and the two ends thereof are fixedly plugged with the two fixing plates 7 respectively; it also includes a bottom box 9, which is fixed to the fixing plates 7, a control component 10 is installed in the bottom box 9, and a spiral pumping component 3 is fixed on the bottom box 9;

[0042] The solar drying assembly 8 includes a heat pipe 801, an inner mesh pipe 802, a ball valve 803 and an extrusion ring 804. The two ends of the heat pipe 801 are fixed by two fixing plates 7 respectively. The inner mesh pipe 802 is in the heat pipe 801. There is an annular cavity 805 between the inner mesh pipe 802 and the heat pipe 801. The upper end of the heat pipe 801 is a closed structure and is equipped with two liquid inlet nozzles 806 connected to the annular cavity 805. The liquid inlet nozzle 806 is fixed and communicated with the connecting pipe A4. The ball valve 803 is fixed at the bottom of the heat pipe 801 and is connected thereto. The bottom outlet of the ball valve 803 is in a conical contraction shape. The extrusion ring 804 is fixed inside the lower end of the heat pipe 801. The bottom end of the inner network tube 802 is located above the extrusion ring 804 and is fixedly installed with a communicating elbow A807. The other end of the elbow A807 passes through the heat pipe 801. The lower end of the heat pipe 801 is located below the extrusion ring 804 and is fixedly installed with a transverse tube 808 communicating with the annular cavity 805.

[0043] The ball valve 803 is located in the bottom box 9 and is controlled to open and close by the control component 10;

[0044] The outer end of the elbow A807 is connected to the connecting pipe B5, and the outer end of the horizontal pipe 808 is connected to the connecting pipe C6.

[0045] The ball valve 803 is an existing structure and can use the specifications of the existing technology with low sealing degree but small rotation resistance, which is convenient for one-time operation of multiple ball valves to open and close at the same time. The use of ball valve 803 can prevent sludge from damaging the valve core.

[0046] The bottoms of the primary treatment box 1 and the secondary treatment box 2 are fixedly installed with supports and can stand on the ground. The primary treatment box 1 is used to receive the residue after treatment by the existing wastewater treatment equipment. The residue at this time is in a muddy state with a large water content. It can be pumped into the primary treatment box 1 for precipitation by a pump. A solenoid valve is installed between the connection between the connecting pipe A4 and the spiral pumping component 3. The connecting pipe A4 can adopt a single pipe to connect all the solar drying components 8 together, or a double pipe to connect two adjacent solar drying components 8 respectively. The connection between the connecting pipe B5 and the primary treatment box 1 is installed with a solenoid valve and a pump, and the connection between the connecting pipe C6 and the secondary treatment box 2 is installed with a solenoid valve and a pump;

[0047] The fixing plate 7 has a specific length, and the number of solar drying components 8 between the fixing plates 7 is limited. In actual use, multiple sets of parallel fixing plates 7 need to be set up and installed together outdoors. At this time, there are more solar drying components 8, and the connecting pipes A4, B5 and C6 between the multiple sets are connected to each other. The primary processing box 1 and the secondary processing box 2 are set at the head and tail. The arrangement and distribution layout of the multiple sets of fixing plates 7 and the solar drying components 8 can be confirmed according to the actual site;

[0048] The heat pipe 801 is a traditional solar glass tube, which heats up when exposed to sunlight and has a smooth interior. The inner mesh tube 802 uses a metal filter mesh folded into a tubular structure to filter wastewater in the sludge. When the sludge is squeezed, the wastewater will enter the inner mesh tube 802 and be discharged. This type of filtration requires external squeezing to allow the wastewater to pass through the mesh of the inner mesh tube 802. Without external squeezing, it is difficult for the wastewater to pass through.

[0049] The solar drying assembly 8 further includes two temperature storage covers 809 , which are respectively located on both sides of the heat pipe 801 . The temperature storage covers 809 are arc-shaped structures, and both ends thereof are respectively fixed to the two fixing plates 7 .

[0050] The temperature storage cover 809 can be a plastic cover with a reflective material coated inside, which can further store heat for the heat pipe 801 and ensure that the temperature fluctuation between two adjacent heat pipes 801 is small.

[0051] The heat pipe 801 is a two-section structure, with the diameter of the upper end being larger than that of the lower end, and a conical transition being used between the two sections. The inner network tube 802 is concentric with both ends of the heat pipe 801, and the annular cavity 805 is divided into two different upper and lower parts.

[0052] The sludge at the upper end has more water content, while the sludge at the lower end has less water content. The further the sludge moves downward, the stronger the squeezing degree is, and the smaller the size of the annular cavity 805 is, the sludge is more affected by temperature. Therefore, the lower end of the heat pipe 801 is more viscous than the upper end, and the wastewater in the sludge will move upward after being heated, so that the thicker annular cavity 805 at the top will also heat up quickly, which can play a preliminary preheating effect. The steam generated after heating will squeeze the inner network pipe 802 and enter the inner network pipe 802, and can also prevent the inner network pipe 802 from being blocked. When the sludge in the heat pipe 801 is squeezed out, the pressure on the sludge at the lower end of the heat pipe 801 is greater. When being squeezed out, the bottom end of the heat pipe 801 is not easily contaminated. The provision of the extrusion ring 804 further increases the pressure when the sludge is squeezed out.

[0053] The control component 10 includes an electric push rod 1001, a pull rod 1002 and a turntable 1003. The pull rod 1002 is located in the bottom box 9. Both ends of the pull rod 1002 use rocker arms for being supported and rotated by the bottom box 9. One end of the electric push rod 1001 is hinged to the side wall of the bottom box 9, and the other end is hinged to one end of the pull rod 1002. The number and position of the turntable 1003 correspond to the solar drying component 8. The turntable 1003 is installed on the pull rod 1002 and is rotatably connected thereto. Two pins 1005 are fixedly installed on one side of any turntable 1003 away from the pull rod 1002. A lever 1004 is fixedly installed on the input shaft of the ball valve 803. The two pins 1005 on a turntable 1003 are respectively clamped on both sides of the lever 1004.

[0054] The electric push rod 1001 is controlled by an external driving component and can be arranged in groups. When contracting and extending, it can drive the opening and closing of multiple ball valves 803 at one time.

[0055] The spiral pumping assembly 3 includes a sleeve 301, a motor 302 and a spiral blade 303. The sleeve 301 is fixed on the bottom box 9, the motor 302 is fixed at the bottom of the sleeve 301, the spiral blade 303 is in the sleeve 301, and its main shaft is supported for rotation by the bottom end of the sleeve 301. The output shaft of the motor 302 is connected to the main shaft of the spiral blade 303. The bottom ends of the primary treatment box 1 and the secondary treatment box 2 are fixedly installed with a curved pipe B304 connected thereto, and the other end of the curved pipe B304 is fixed and connected to the bottom side wall of the sleeve 301, and the upper end of the sleeve 301 is fixed and connected to one end of the connecting pipe A4.

[0056] The sediments in the primary treatment tank 1 and the secondary treatment tank 2 can be transferred to the sleeve 301, and a pump can be installed at the connection. The spiral blade 303 is used to rotate and drive the sludge, which can increase the pressure of the sludge. When pushing, the high pressure can also squeeze out the wastewater in the sludge, so that the sludge is not only baked at high temperature, but also subjected to high pressure. The spiral blade 303 uses an upward pumping method to bring the sludge to the connecting pipe A4 and enter from the upper end of the heat pipe 801.

[0057] The connecting pipe B5 and the connecting pipe C6 are respectively located on both sides of the bottom end of the heat pipe 801. The connecting pipe B5 and the connecting pipe C6 are installed with interconnected bent pipes C11 at the ends away from their seals. The other ends of the two bent pipes C11 are respectively connected to the upper end of the primary processing box 1 or the upper end of the secondary processing box 2.

[0058] The elbow C11 is a longitudinal structure. The elbow C11 connected to the connecting pipe C6 has a trumpet cover 12 fixedly installed at one end thereof away from the connecting pipe C6. The diffusion end of the trumpet cover 12 is fixed to the upper end of the secondary treatment box 2 and communicates with the interior thereof.

[0059] It also includes a corrugated drying plate 13, which is arranged below the bottom box 9, and the corrugated groove of the plate corresponds to the output end of the ball valve 803.

[0060] The corrugated drying board 13 is made of soft material. When the sludge is poured onto the corrugated drying board 13 , it can flow along the corrugations. After being exposed to sunlight again and dried, the corrugated drying board 13 can be rolled up. When rolled up, the sludge can be easily removed.

[0061] When in use, the primary treatment box 1 is used to receive wastewater from the previous treatment step and can be connected by a pipeline. The wastewater at this time should be the wastewater that has been coarsely filtered in the previous step. The wastewater contains more sludge and is in a muddy state. The wastewater in the primary treatment box 1 will be left to settle inside, and then the sediment below will enter the sleeve 301, and then be pumped into the connecting pipe A4 as the spiral blade 303 rotates, and then pumped into multiple heat pipes 801. The heat pipe 801 will heat up after being exposed to the sun. Since the annular cavity 805 at the bottom of the heat pipe 801 has a smaller diameter, the evaporation efficiency is higher, and the heat will rise, so the larger annular cavity 805 at the upper end will be preheated and evaporated first, and the bottom The smaller annular cavity 805 focuses on evaporating the precipitated sludge. When pumping, the spiral blades 303 squeeze the wastewater, and the excess water in the wastewater enters the inner network pipe 802. The evaporated steam is also pushed into the inner network pipe 802 under pressure, and then recirculated to the primary treatment tank 1 for further precipitation treatment. The sludge-like wastewater will not be discharged directly, but will be pushed into the secondary treatment tank 2 for further precipitation, and then pumped back into the heat pipe 801 by the spiral pumping component 3, and then returned to the heat pipe 801 for the first treatment, and the less viscous sludge in the heat pipe 801 will be squeezed out and replaced with viscous sludge, and then discharged through the ball valve 803 after one cycle;

[0062] Alternatively, the connecting pipe A4 adopts double pipe control, and the wastewater pumped by the primary treatment box 1 and the wastewater pumped by the secondary treatment box 2 pass through different heat pipes 801 respectively. The heat pipes 801 through which the two are pumped are arranged alternately. At this time, not only the secondary heating effect is achieved, but also the heat can be utilized to the maximum extent, ensuring that the temperature fluctuation of the heat pipe 801 is small.
