Description
A shockproof and sediment-proof residue collection device Technical Field
[0001] This utility model relates to a residue collection device, specifically a vibration-proof and sediment-proof residue collection device, belonging to the field of residue collection devices. Background Technology
[0002] my country's municipal solid waste has a high water content, resulting in large quantities of leachate with high pollutant concentrations and a wide range of water quality variations, making treatment significantly more difficult than in developed countries in Europe and America. Currently, most landfill leachate requires combined treatment processes to meet the pollutant discharge concentration limits required by standards. The mainstream process is biological treatment combined with membrane treatment. While the mainstream "enhanced biological treatment + membrane reactor" process effectively ensures that the effluent meets discharge standards, the membrane concentrate produced by membrane technology, which is rich in high concentrations of organic matter and salts, is difficult to treat. The membrane concentrate has a CODcr of 3500-8000 mg / L and a conductivity of 35-150 mS / cm. Submerged combustion evaporation (SCE) technology, based on the principle of direct contact heat transfer, is an evaporation method without a fixed heat transfer surface. High-temperature flue gas comes into direct contact with the liquid to be evaporated, and the heat transfer efficiency is generally as high as 95% or more, achieving efficient evaporation of the concentrate. High-concentration pollutants are discharged and solidified in the form of residue or crystals. The saturated residual liquid produced after evaporation of the membrane concentrate flows by gravity into a residue collector. The residue collector is a transfer tank for the evaporation residue and salt mud deposits at the bottom of the evaporator. The concentration of the saturated evaporation residue can reach 10-20 times or more of the influent membrane concentrate. Under high concentration ratios, crystallization residue containing organic matter is completely precipitated.
[0003] However, traditional residue collection devices used in immersion fuel evaporators for treating membrane concentrates have the following problems:
[0004] 1. During the operation of traditional residue collection devices, residue and residual liquid are prone to stratification. The moisture content of the residue in the upper part of the device is low, which causes some residue to adhere to the side wall or bottom of the device, resulting in incomplete slag discharge and reduced slag discharge rate.
[0005] 2. Traditional residue collection devices have a horizontal bottom, and residue located in the corners of the device tends to accumulate, resulting in incomplete removal of residue and reduced effective utilization of the device.
[0006] 3. Traditional residue collection devices will experience irregular oscillations and continuous vibrations during operation due to the influence of the upper evaporator. After long-term continuous operation, the device will deform externally, and in severe cases, the equipment will be damaged and the collection device will need to be replaced.
[0007] 4. Traditional residue collection devices cannot monitor the amount of residue discharged in real time, control the frequency and amount of residue discharge, and require a high degree of manual monitoring.
[0008] 5. Traditional residue collection devices have complex structures, occupy a large space, and are prone to corrosion. Summary of the Invention
[0009] The purpose of this invention is to design a vibration-proof and sediment-proof residue collection device, which can effectively prevent residue from settling at the bottom. At the same time, the vibration-proof function of the residue collection device can effectively reduce the impact of surge on the sedimentation tank, maximize the service life of the residue collection device, and reduce the cost of treating membrane concentrate to a certain extent.
[0010] The technical solution of this utility model is as follows:
[0011] A vibration-proof and sediment-proof residue collection device includes a housing equipped with a residue stirring device; an inclined filter plate is installed at the bottom of the housing, and a water hammer absorber is installed at the top of the housing; an inlet is located on one side of the housing, and an outlet is located on the other side of the bottom; an inspection port is located at the top of the housing. The water hammer absorber at the top of the housing includes a cylinder, the bottom of which is connected to the housing; a piston is installed inside the cylinder, and a sealing ring is installed outside the piston. The downward flow of the distilled residual liquid impacts the piston, causing it to move towards the cylinder. The piston moves up and down under the combined action of a certain pressure of gas and the irregular impact of the distilled residual liquid, forming a dynamic balance, thus eliminating the irregular impact and vibration of the distilled residual liquid.
[0012] Furthermore, the cylinder is equipped with a pressure gauge and an inflation valve at the top. The pressure gauge is located at the top of the cylinder, and the inflation valve is located below the pressure gauge. The inflation valve is welded to the outer shell of the cylinder.
[0013] Furthermore, the conveying pipe of the submerged combustion evaporator is connected to the feed inlet of the housing via a flange, and the concentrated liquid remaining after evaporation enters the housing through the feed inlet.
[0014] The membrane concentrate remaining after treatment in the immersion combustion evaporator, along with the residue generated after crystallization, enters the tank through the feed inlet via a pipeline. Once inside the tank, the residue is uniformly stirred with the evaporation residue by a residue stirring device.
[0015] Furthermore, the inspection port is equipped with a sealing quick-opening valve, which facilitates opening and prevents odors from escaping.
[0016] Furthermore, an electronic weighing device is installed at the bottom of the box.
[0017] Furthermore, the stirring device is located in the middle of the housing and consists of a stirring motor, a stirring shaft, and stirring blades. The stirring motor is located at the top of the housing, and the upper end of the stirring shaft is rotatably connected to the stirring motor, while the other end extends into the bottom of the housing. The stirring blades are vertically and fixedly connected to the stirring shaft. The number of stirring blades is 4-8, and adjacent stirring blades are arranged at equal angles with the stirring shaft as the center. The height of the stirring blades can be adjusted according to the feed rate and the sedimentation area, and three heights can be adjusted. The stirring speed is 82-120 rpm, and the height can be automatically controlled by adjusting the matching density meter.
[0018] The inspection port is located at the top of the housing and extends from the top of the housing through a riser. A quick-opening valve is installed on the end cap on the outer surface of the inspection port, and a sealing ring is installed at the junction of the pipe and the end cap. The outer diameter of the riser matches the inner diameter of the inspection port end cap. This allows for rapid troubleshooting, cleaning, and repair when the residue collection device malfunctions.
[0019] The bottom of the housing is equipped with an inclined filter plate at an angle of 30° to the horizontal plane. The surface of the inclined filter plate is coated with a special ceramic coating, which can improve the smoothness of the inclined plate and effectively reduce the accumulation of residue. When residue settles at the bottom, it will accumulate along the inclined plate to one side of the design, reducing the residue accumulation area and volume, and making it easier to clean.
[0020] Below the inclined filter plate is an electronic weighing device, which includes a weighing platform, a junction box, a sensor, and a foundation. The junction box connects to the high-precision sensor. The foundation is a bottom plate with a recessed bottom, providing support and preventing residual liquid from overflowing and corroding the equipment. The electronic weighing device can interlock with the slag discharge pump according to a set weight. Once the slag discharge pump is activated, automatic material discharge is achieved, reducing the intensity of manual operation.
[0021] A discharge port is located on the bottom right side of the outer casing, and the residual liquid from the distillation enters the slag-water separation device through the pipe connected to the discharge port.
[0022] The beneficial effects of this utility model are as follows:
[0023] (1) Made of high temperature resistant stainless steel, cylindrical box with moderate size, lightweight, corrosion resistant, anti-aging, suitable for high conductivity and high TDS media;
[0024] (2) An internal residue stirring device is provided. The stirring device relies on the stirring motor to drive the stirring shaft and uses the stirring blades to mix the residue and liquid evenly, so that the residue maintains a suitable humidity, prevents the residue from sticking to the inner wall of the device, and improves the slag discharge efficiency.
[0025] (3) The inclined filter plate can separate the residue from the liquid; it forms an angle with the bottom of the device, which can prevent the residue from accumulating in large quantities at the bottom of the device. In addition, the filter holes are evenly distributed on the surface of the inclined filter plate, which improves the residue filtration effect and increases the slag discharge rate.
[0026] (4) A water hammer absorber is used, which has a piston inside. Under the dual action of a certain pressure of gas and irregular water hammer, the piston forms a dynamic balance, which can effectively eliminate the irregular water hammer wave oscillation and prevent the device from deforming during long-term continuous operation.
[0027] (5) The stirring blades are made of polymer materials and their height can be automatically adjusted according to the feed rate and density meter after interlocking. They have a longer service life, a unique treatment method, and obvious effects.
[0028] (6) An automatic weighing system is set up, which can automatically discharge materials after interlocking with the slag discharge pump according to the set weight, thereby reducing the intensity of manual operation and controlling the slag discharge cycle.
[0029] (7) The inspection port set on the top of the device facilitates troubleshooting, cleaning and repair when the residue collection device malfunctions.
[0030] The present invention will be further described below with reference to the accompanying drawings and embodiments. Attached Figure Description
