Description

Technical Field

[0001] This utility model relates to the technical field of sludge treatment, specifically to a sludge treatment waste gas separation and collection device. Background Technology

[0002] With the rapid increase in urban population and socio-economic development in my country, the amount of urban sewage generated has increased dramatically. This increased demand for sewage treatment has led to greater pressure on sludge management. Furthermore, the natural degradation time of sludge is long; existing sludge doesn't degrade before new sludge accumulates, polluting the land and surrounding environment. Over time, this will severely impact the urban ecological environment and hinder urban development. Current urban sewage treatment plants primarily use sludge reduction technology to reduce sludge volume. However, existing sludge treatment technologies are inefficient and energy-intensive, resulting in high costs. Moreover, current sludge treatment technologies do not treat the emitted exhaust gases, which pollute the environment.

[0003] A prior art "stirring and drying device" is disclosed in Chinese Patent Application No. 201310464982.5, Publication No. CN103508649B. This invention relates to a stirring and drying device, comprising a tank with a heating jacket on its side wall. The tank is characterized by a main shaft and a rotating drum connected to the main shaft via an intermediate rod. Several layers of spiral conveyor belts with equal pitch are arranged on the outer periphery of the rotating drum. A material drying channel is provided between the spiral conveyor belts and the side wall of the tank. This invention has a simple structure, rapid stirring, and high drying efficiency, effectively improving the efficiency and effect of sludge drying treatment, and also ensuring the reliability of equipment operation, thus possessing broad market prospects.

[0004] However, the existing technologies do not have a related exhaust gas purification and treatment structure, and the existing urban sludge contains a large number of pollutants. The exhaust gas produced during the heating and drying process contains a variety of complex components. Therefore, a device that can separate the internal gases of the exhaust gas is needed to improve the collection and utilization efficiency of the exhaust gas. Utility Model Content

[0005] The purpose of this invention is to provide a sludge treatment waste gas separation and collection device that can quickly separate and collect different gases from waste gas.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A sludge treatment waste gas separation and collection device includes a support frame with several separation cylinders screwed onto the support frame. Ventilation pipes are fixed to both ends of each separation cylinder. Connecting pipes are screwed to the flanges at the ends of the ventilation pipes furthest from the separation cylinders. A first solenoid valve is fixed to the outside of each connecting pipe. A temperature control rod is inserted inside each separation cylinder. A pressure control pipe is also fixed to the side of each separation cylinder. A second solenoid valve is fixed to the outside of the pressure control pipe. A pressure monitoring gauge and a temperature monitoring gauge, inserted inside the separation cylinder, are located on the side of the pressure control pipe.

[0008] Furthermore, the temperature control rod includes a condenser and a resistance heating rod located on the side of the condenser, both of which are inserted into the side of the separation cylinder.

[0009] By adopting the above technical solution, it is convenient to control the temperature environment inside the separation cylinder, so as to achieve independent control of each separation cylinder.

[0010] Furthermore, the separating cylinder has an opening facing the support, and an outlet pipe is threaded inside the opening. A third solenoid valve is fixed outside the outlet pipe.

[0011] By adopting the above technical solution, it is convenient to collect the liquefied gas.

[0012] Furthermore, a fixed frame is fixed inside one of the ventilation pipes, and a rotating shaft is rotatably connected inside the fixed frame. A first bevel gear is fixed outside the rotating shaft, and a second bevel gear meshes with the first bevel gear. A drive shaft is fixed inside the second bevel gear, and the drive shaft extends toward one side of the ventilation pipe. A motor is connected to the extended end of the drive shaft, and the motor is fixed outside the ventilation pipe.

[0013] Furthermore, a fixed plate is fixed to the end of the rotating shaft away from the fixed frame, and several inclined connecting rods are fixed to the side of the fixed plate. Ring blocks are fixed to the side of the connecting rods, and several ring blocks are arranged along the axis of the rotating shaft. All the connecting rods form a conical structure.

[0014] By adopting the above technical solution, after the exhaust gas enters, the connecting rod can be driven to rotate by the motor. The conical guide structure formed by the connecting rod increases the rate of exhaust gas entry and avoids the exhaust gas from staying inside the connecting pipe for too long, thereby improving the exhaust gas treatment and separation efficiency.

[0015] Furthermore, flanges are welded to both ends of the connecting pipe.

[0016] By adopting the above technical solution, it is possible to facilitate the connection between ventilation pipes or the connection between ventilation pipes and the exhaust gas inlet.

[0017] In summary, the beneficial technical effects of this utility model are as follows:

[0018] 1. It adopts a separation cylinder. By setting up multiple independent separation cylinders, the temperature and pressure of each separation cylinder can be controlled independently to achieve liquefaction conditions for different types of gases, and can quickly separate and collect waste gas.

[0019] 2. The system adopts a connecting rod and a motor drive. After the exhaust gas enters, the motor drives the connecting rod to rotate. The conical guide structure formed by the connecting rod increases the rate of exhaust gas entry and avoids the exhaust gas from staying inside the connecting pipe for too long, thereby improving the exhaust gas treatment and separation efficiency.

[0020] 3. Solenoid valves are used, and different first, second and third solenoid valves are set to facilitate the control of air intake and exhaust of the separation cylinder. At the same time, the separation cylinder can be kept in a closed environment to facilitate gas separation. Attached Figure Description

[0026] The present invention will be further described in detail below with reference to the accompanying drawings.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-3 This utility model provides a technical solution: a sludge treatment waste gas separation and collection device, including a support 1, a plurality of separation cylinders 2 are screwed on the support 1, and ventilation pipes 3 are fixed at both ends of the separation cylinders 2. The flange of the ventilation pipe 3 away from the separation cylinder 2 is fixed with a connecting pipe 4 by screws. A first solenoid valve 5 is fixed to the outside of each connecting pipe 4. A temperature control rod is inserted into the inside of the separation cylinder 2. A pressure control pipe 6 is also fixed to the side of the separation cylinder 2. A second solenoid valve 7 is fixed to the outside of the pressure control pipe 6. A pressure monitoring gauge 8 and a temperature monitoring gauge 9 are provided on the side of the pressure control pipe 6 and inserted into the inside of the separation cylinder 2.

[0029] The temperature control rod includes a condenser 10 and a resistance heating rod 11 located on the side of the condenser 10. Both the condenser 10 and the resistance heating rod 11 are inserted into the side of the separation cylinder 2.

[0030] In this embodiment, the condenser 10 and the resistance heating rod 11 are both conventional products in the art. They can both control the ambient temperature inside the separation cylinder 2, and the internal temperature of the separation cylinder 2 can be monitored by the temperature monitoring table 9 so as to adjust the internal temperature of the separation cylinder 2.

[0031] Meanwhile, each separation cylinder 2 has an opening 12 facing the support 1. The opening 12 is threaded with an outlet pipe 13. A third solenoid valve 14 is fixed to the outside of the outlet pipe 13. The opening and closing of the outlet pipe 13 is controlled by the third solenoid valve 14.

[0032] One of the ventilation pipes 3 has a fixed bracket 15 inside, and a rotating shaft 16 is rotatably connected inside the fixed bracket 15. A first bevel gear 17 is fixed outside the rotating shaft 16. A second bevel gear 18 meshes with the first bevel gear 17. A drive shaft 19 is fixed inside the second bevel gear 18. The drive shaft 19 extends toward the ventilation pipe 3. A motor 20 is connected to the extended end of the drive shaft 19. The motor 20 is fixed outside the ventilation pipe 3.

[0033] A fixed plate 21 is fixed to the end of the rotating shaft 16 away from the fixed frame 15. Several inclined connecting rods 22 are fixed to the side of the fixed plate 21. Ring blocks 23 are fixed to the side of the connecting rods 22. Several ring blocks 23 are arranged along the axis of the rotating shaft 16. All the connecting rods 22 form a conical structure.

[0034] Then, after the motor 20 is turned on, the motor 20 can drive the drive shaft 19 to rotate, which in turn drives the second bevel gear 18. The meshing connection between the second bevel gear 18 and the first bevel gear 17 drives the first bevel gear 17 to rotate, which in turn drives the overall fixed disk 21 and connecting rod 22 to rotate.

[0035] In this embodiment, the number of separation cylinders 2 can be set according to the types and quantities of gases detected in the exhaust gas. A fixing frame 15 is set inside the ventilation pipe 3 near the exhaust gas discharge side. After the exhaust gas enters, the connecting rod 22 can be driven to rotate by the motor 20. The conical flow guiding structure formed by the connecting rod 22 is used to increase the rate of exhaust gas entry and avoid the exhaust gas from staying in the connecting pipe 4 for too long, thereby improving the exhaust gas treatment and separation efficiency.

[0036] Meanwhile, flanges 24 are welded to both ends of the connecting pipe 4 to facilitate the connection between ventilation pipes 3 or between ventilation pipes 3 and the exhaust gas inlet.

[0037] The working principle of this utility model is as follows: Different types of gases are liquefied at different temperatures, that is, the different liquefaction temperatures of other gases create a high-pressure constant temperature environment inside the separation cylinder 2. The temperature is regulated by the condenser 10 or the heating resistance rod. At the same time, nitrogen is introduced into the separation cylinder 2 through the pressure control pipe 6 to control the pressure. Since the liquefaction temperature of nitrogen is lower than that of all gases in the waste gas, the pressure inside the separation cylinder 2 can be controlled by controlling the amount of nitrogen introduced. The pressure is also observed through the pressure monitoring gauge 8.

[0038] Specifically, one of the separation cylinders 2 is installed at one end of the connecting pipe 4, and the other end of the connecting pipe 4 is connected to the exhaust gas outlet. The other separation cylinders 2 are connected in sequence. After the exhaust gas enters the first separation cylinder 2, the second solenoid valve 7 on the pressurization control pipe 6 is opened and the corresponding liquefaction temperature is set. At the same time, the first solenoid valve 5 between the separation cylinder 2 and the next separation cylinder 2 is closed. At this time, a sealed environment is formed inside the separation cylinder 2. At the corresponding liquefaction temperature, the corresponding gas can be converted into a liquid state. Then, the first solenoid valve 5 is opened again to introduce the remaining gas into the next separation cylinder 2. At the same time, the third solenoid valve 14 is opened to discharge and collect the liquid gas along the outlet pipe 13. In this way, the gas inside the exhaust gas is separated one by one.

[0039] In this embodiment, under an atmospheric pressure environment, the liquefaction temperature of sulfur dioxide is -10°C, and the liquefaction temperature of carbon dioxide is -78.4°C.
