Description

Technical Field

[0001] This utility model relates to the field of sludge treatment technology, and in particular to a wastewater sludge treatment device. Background Technology

[0002] In the wastewater treatment process, the wastewater is first filtered, and the filtered sludge enters a sludge drying tank. The dehydrated and dried sludge can be used as fuel. The traditional method is to directly incinerate the sludge in a sludge incinerator. However, the waste heat generated during the incineration process cannot be effectively utilized.

[0003] The existing utility model patent with publication number CN207584782U discloses a wastewater and sludge treatment device, which has a heating chamber and a dust removal box outside the incinerator. The hot gas in the incinerator enters the heating chamber through a first duct to heat the cold water in the water storage chamber, thereby improving the utilization rate of waste heat. Moreover, the dust removal box can remove dust from the exhaust gas, thereby reducing air pollution. However, it directly introduces flue gas into the heating chamber, and the contact area between the flue gas and water is relatively limited. The time and path of the flue gas in the heating chamber are also relatively short, which can easily lead to poor heating effect of the flue gas on the water and insufficient utilization of the waste heat of the flue gas. Therefore, we need to upgrade and modify the existing technology to overcome the existing problems and shortcomings. Utility Model Content

[0004] The purpose of this invention is to provide a wastewater and sludge treatment device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] Design a wastewater sludge treatment device, including a device body, which includes an incineration chamber, a recovery component and a filtration component. A burner is provided on one side of the lower end of the incineration chamber and a feed inlet is provided on the other side. An exhaust pump is connected to the top of the incineration chamber and an exhaust pipe is provided at the outer end of the exhaust pump. The filtration component is connected to the outer end of the exhaust pipe and the recovery component is connected to the rear end of the filtration component.

[0007] The recycling assembly includes a water storage tank and an air guide pipe. The water storage tank has an inlet and an outlet on its outer wall, and the air guide pipe is fixed inside the water storage tank with an air inlet and an air outlet at both ends.

[0008] Preferably, the filter assembly includes a filter box, with pipes on both sides of the filter box being connected to an exhaust pipe and an air inlet, respectively. The filter box contains a filter screen and has a sealing cover installed at its top.

[0009] Preferably, the air guide pipe is configured as a spiral coil structure, and the air inlet and air outlet extend to the outside of the water storage tank.

[0010] Preferably, the inner wall of the water storage tank is provided with a heat insulation layer, and the outer side of the air guide pipe is fitted with a fixing sleeve, which is installed on the inner wall of the heat insulation layer.

[0011] Preferably, the filter box has an insertion slot at its upper end, and the filter screen has a mounting bracket on its outer side, which is inserted into the insertion slot.

[0012] Preferably, the sealing cover has two sets of limiting holes, and bolts are screwed to both sides of the filter box, with limiting rods fixed on the bolts. The limiting rods are connected to the limiting holes.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model includes a recovery component, a water storage tank, an insulation layer, a water inlet, a water outlet, a gas guide pipe, an air inlet, an air outlet, and a fixing sleeve. An exhaust pump pumps combustion waste gas into the gas guide pipe, which then allows the gas to swirl through the water storage tank. This enables the recovery and reuse of combustion waste heat, facilitates heating of the water in the storage tank, and ensures sufficient contact between the water and the swirling gas guide pipe, effectively achieving efficient heat exchange, reducing energy consumption, minimizing environmental pollution, and improving the practicality of the equipment.

[0015] 2. This utility model, through the installation of a filter assembly, filter box, insertion slot, mounting bracket, filter screen, sealing cover, limiting hole, bolts, and limiting rod within the device, enables the mounting bracket and filter screen to be inserted and installed via the insertion slot, and the sealing cover to be fixed via the limiting hole and limiting rod. This allows for the filtration of flue gas entering the recovery assembly, effectively removing particulate matter and impurities from the flue gas, preventing impurities and particulate matter from adhering to the inner wall of the pipe, and preventing them from affecting the pipe's heat conduction effect and service life.

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] like Figure 1 As shown in Figure 4, the wastewater sludge treatment equipment provided in this embodiment includes a device body 1. The device body 1 includes an incineration chamber 2, a recovery component 4, and a filter component 5. A burner 21 is provided on one side of the lower end of the incineration chamber 2 and a feed inlet 22 is provided on the other side. An exhaust pump 3 is connected to the top of the incineration chamber 2 and an exhaust pipe 31 is provided at the outer end of the exhaust pump 3. The filter component 5 is connected to the outer end of the exhaust pipe 31, and the recovery component 4 is connected to the rear end of the filter component 5.

[0025] In this embodiment, the recovery component 4 includes a water storage tank 41 and a gas guide pipe 45. The water storage tank 41 has an inlet 43 and an outlet 44 on its outer wall. The gas guide pipe 45 is fixed inside the water storage tank 41 and has an inlet 46 and an outlet 47 at both ends. The gas guide pipe 45 is configured as a spiral coil structure. The inlet 46 and outlet 47 extend to the outside of the water storage tank 41. The inner wall of the water storage tank 41 is provided with a heat insulation layer 42. A fixing sleeve 48 is fitted on the outside of the gas guide pipe 45 and is installed on the inner wall of the heat insulation layer 42. The exhaust gas is pumped into the gas guide pipe 45 by the exhaust pump 3. The gas is swirled through the water storage tank 41 through the gas guide pipe 45, thereby realizing the recovery and reuse of combustion waste heat. This facilitates the heating of the water in the water storage tank 41. The water and the swirling gas guide pipe 45 are in full contact, effectively achieving efficient heat exchange, reducing energy consumption, reducing environmental pollution, and improving the practicality of the equipment.

[0026] In this embodiment, the filter assembly 5 includes a filter box 51. The pipes on both sides of the filter box 51 are connected to the exhaust pipe 31 and the air inlet 46, respectively. The filter box 51 is equipped with a filter screen 54 and a sealing cover 55 is installed on the upper end. The filter box 51 has an insertion groove 52 at the upper end. The filter screen 54 has an installation bracket 53 on the outside and the installation bracket 53 is inserted into the insertion groove 52. The sealing cover 55 has two sets of limiting holes 56. Bolts 57 are screwed to both sides of the filter box 51 and limiting rods 58 are fixed on the bolts 57. The limiting rods 58 are connected to the limiting holes 56. The installation bracket 53 and the filter screen 54 are inserted and installed through the insertion groove 52. The sealing cover 55 is fixed through the limiting holes 56 and the limiting rods 58. This can achieve the filtration treatment of the flue gas entering the recovery assembly 4, effectively remove particulate matter and impurities in the flue gas, prevent impurities and particulate matter in the flue gas from adhering to the inner wall of the pipe, and prevent them from affecting the heat conduction effect and service life of the pipe.

[0027] The working principle and process of this utility model are as follows: During use, sludge is placed in the incineration chamber 2 through the feed inlet 22. The burner 21 heats and dries the sludge. During the sludge drying process, the generated flue gas enters the filter box 51 through the exhaust pump 3 and exhaust pipe 31. After being filtered by the filter screen 54, it continues to be guided into the air guide pipe 45 and finally discharged from the air outlet 47. After the filter screen 54 has been used for a period of time, the bolt 57 can be rotated to move the limiting rod 58 upward and align it with the limiting hole 56. Then, the sealing cover 55 can be removed, and the mounting bracket 53 can be pulled out from the insertion slot 52 to replace the filter screen 54. The operation is simple and convenient. When the flue gas passes through the air guide pipe 45, it can heat the water inside the water storage tank 41. The spiral air guide pipe 45 more effectively ensures the contact time and area between the flue gas and water, improving the heating effect of the water and effectively ensuring the utilization rate of combustion resources.
