Description
Technical Field
[0001] This invention relates to a pipeline mixing deodorization and odor suppression, detection, adjustment and alarm device, belonging to the technical field of special equipment for sanitation vehicles. Background Technology
[0002] As a primary vehicle for the maintenance and dredging of urban pipe networks, the sludge treatment vehicle integrates functions such as mobile operation, motorized dredging, and sludge dewatering. It is an important sanitation vehicle for ensuring the smooth flow of sewage and flood discharge in urban drainage pipe networks.
[0003] However, these sanitation vehicles typically use a box-type cargo platform, with all sludge removal and dewatering equipment housed inside the cargo compartment. Furthermore, during sludge suction operations, the sludge processing and transfer between the various devices within the vehicle is not a completely enclosed, non-contact process. Therefore, when handling putrefactive sludge, large amounts of ammonia nitrogen odor or other harmful mixed gases are often released. In such cases, all cargo compartment doors must be fully opened; otherwise, it poses a health hazard to workers who are constantly near the equipment. However, doing so also releases the ammonia nitrogen odor and other harmful mixed gases into the surrounding environment, affecting residents' lives and causing short-term air pollution. If a closed operation is forced to avoid odor disturbance, the odor released by the sludge accumulates inside the cargo compartment, posing a significant risk of poisoning and explosion for the operators inside.
[0004] Therefore, how to effectively decompose or suppress harmful gases in the sludge within the pipeline during the sludge treatment and transfer process, especially before the sludge undergoes non-closed transfer procedures, and how to detect and warn of the concentration of harmful gases before the sludge leaves the pipeline, has become an important technological innovation requirement for improving the applicability, operational safety, and environmental friendliness of such vehicles. Summary of the Invention
[0005] The purpose of this invention is to provide a pipeline mixing, deodorizing, odor suppression, detection, regulation, and alarm device to solve the safety hazards of sludge suction and transportation generated during the operation in a closed space when dealing with sludge in drainage ditches.
[0006] A pipeline mixing deodorization and odor suppression and detection and adjustment alarm device, characterized in that it includes a feed pipe section, a drain pipe, a discrete pipe, a double Venturi jet siphon pipe, a spiral pipe, a drainage pipe, a gas collection device, an ammonia nitrogen gas sensor, a control cabinet, a deodorant storage tank, an ozone generator, a frame, a three-way drain valve, a chemical interception control valve, a chemical delivery pipe, and an ozone delivery pipe;
[0007] Using the frame as an installation platform, a dual-inlet jet mixing pipeline with Venturi effect is sequentially installed below the frame, consisting of an inlet pipe section, a discrete pipe, a double Venturi jet siphon, a spiral pipe, a drainage pipe, a gas collection device, and an ammonia nitrogen gas sensor. This allows the slurry jet entering the pipeline to be dispersed and vented through the discrete pipe, while the double Venturi jet siphon mixes ozone and deodorizing agent. The spiral pipe induces secondary mixing through rotational friction, decomposing ammonia nitrogen and inhibiting other harmful gases in the slurry. This achieves the decomposition and inhibition of slurry within the pipeline before it leaves the pipe. The mud jet is stabilized by a diversion pipe installed at the outlet of the spiral tube and enters a gas collection device installed at the outlet of the diversion pipe. The gas collection device has an ammonia nitrogen gas sensor built into the top. The ammonia nitrogen gas sensor receives the concentration of ammonia nitrogen gas carried away by the mud leaving the tube, realizing the acquisition, monitoring and alarm of the concentration of ammonia nitrogen gas leaving the tube. Through the control cabinet, the chemical interception control valve and the three-way drain valve are controlled to adjust the dosage of deodorant in the chemical delivery pipe and the total flow rate of mud entering the discrete pipe, so as to control, regulate and detect the concentration of ammonia nitrogen gas leaving the tube.
[0008] Furthermore, the top of the frame is equipped with an ozone generator, a deodorant storage tank, and a control cabinet; the deodorant storage tank is connected to the double Venturi jet siphon via a chemical delivery pipe, and the chemical delivery pipe is equipped with a chemical interception control valve; the ozone generator is connected to the chemical interception control valve; the control cabinet controls the deodorant interception control valve, the three-way drain valve, and the ozone generator based on the signal fed back by the ammonia nitrogen sensor. When no ammonia nitrogen gas is discharged from the sludge in the pipeline through the discharge port or when the gas level is lower than the set hazard value, the control cabinet does not start the ozone generator and the deodorant interception control valve, the three-way drain valve is in a straight-through state with the main pipeline, and the chemical interception control valve is in a closed state.
[0009] Furthermore, the discretization pipe includes a flange, a discretizer, and a mud pipe. There are two flanges, which are welded to both ends of the mud pipe respectively. The discretizer is welded inside the mud pipe near the mud input direction.
[0010] Furthermore, the dual Venturi jet siphon includes an inlet flange, a front overflow pipe, an inner constriction pipe I, an inner constriction pipe II, a sleeve, a jet throat, a diffuser, and an outlet flange. The inlet flange is welded to the front overflow pipe as a whole. The outlet end of the inner wall of the pipe is welded to the diameter end of the inner constriction pipe I. The sleeve has holes spaced apart. A siphon connector I and a siphon connector II are welded to the holes respectively. The inner constriction pipe II is prefabricated and welded inside the sleeve. The inlet end of the sleeve is inserted into the inner constriction pipe I and welded to the front overflow pipe as a whole. The outlet end of the sleeve is welded to the jet throat. One diameter of the jet throat is welded to the outlet end of the sleeve, and the other diameter is welded to the inlet end of the diffuser. The outlet end of the diffuser is welded to the outlet flange.
[0011] Furthermore, the spiral pipe includes two flanges, a mud pipe, and spiral blades. There are two flanges, which are welded to both ends of the mud pipe respectively. There are a number of spiral blades, which are evenly distributed and welded inside the mud pipe.
[0012] Furthermore, the gas collection device includes a feed pipe with a flange, a gas collection box, a mud guide plate, a shielding plate, and a top cover plate. The feed pipe is welded to the gas collection box. The top cover plate is bolted to the top of the gas collection box, and the bottom is an opening. The box is sealed around its perimeter with plates. One side connected to the feed pipe has an opening and is welded to the feed pipe. The top cover plate has a circular hole. The central circular hole is used to install an ammonia nitrogen gas sensor, and the other circular hole is used for gas exchange.
[0013] Compared with the prior art, the beneficial effects achieved by the present invention are as follows:
[0014] The equipment of this invention enables the sludge treatment truck to perform chemical and gas mixing to decompose and suppress harmful gases such as ammonia, nitrogen, and odor that pose a risk to construction safety and human health before suctioning and treating sludge inside the truck. It can also monitor and regulate the entrained gases in the sludge leaving the pipe, ensuring the safety of construction and personnel in the on-site treatment of sludge in closed-loop pipeline dredging systems, such as the sludge treatment truck.

[0022] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.
[0023] like Figures 1-6 As shown, a pipeline mixing deodorization and odor suppression and detection and adjustment alarm device is disclosed, comprising an inlet pipe section 1, a drain pipe 2, a discrete pipe 3, a double Venturi jet siphon pipe 4, a spiral pipe 5, a drainage pipe 6, a gas collection device 7, an ammonia nitrogen gas sensor 8, a control cabinet 9, a deodorant storage tank 10, an ozone generator 11, a frame 12, a three-way drain valve 13, a chemical interception control valve 14, a chemical delivery pipe 15, and an ozone delivery pipe 16;
[0024] Using the frame 12 as the installation platform, the following components are installed sequentially below the frame: feed pipe section 1, discrete pipe 3, double Venturi jet siphon pipe 4, spiral pipe 5, drainage pipe 6, gas collection device 7, and ammonia nitrogen gas sensor 8. This forms a dual-inlet jet mixing pipe with Venturi effect. The slurry jet entering the pipe can be dispersed and released through the discrete pipe 3, the double Venturi jet siphon pipe 4 can siphon and mix ozone and deodorant, and the spiral pipe 5 can generate a secondary mixing through rotational friction of the fluid. This decomposes ammonia nitrogen and integrates and suppresses other harmful gases in the slurry, achieving the decomposition and suppression of slurry in the pipe before it leaves the pipe. The mud jet is stabilized by a diversion pipe 6 installed at the outlet of the spiral pipe and enters a gas collection device 7 installed at the outlet of the diversion pipe 6. An ammonia nitrogen gas sensor 8 is built into the top of the gas collection device 7. The ammonia nitrogen gas sensor 8 receives the concentration of ammonia nitrogen gas carried away by the mud leaving the pipe, realizing the acquisition, monitoring and alarm of the concentration of ammonia nitrogen gas leaving the pipe. The control cabinet 9 controls the chemical interception control valve 14 and the three-way drain valve 13 to adjust the dosage of deodorant chemical delivery pipe 15 and the total flow rate of mud entering the discrete pipe 3, thereby realizing the control, regulation and detection of the concentration of ammonia nitrogen gas leaving the pipe.
[0025] Frame 12 serves as the installation reference. The frame consists of an equipment mounting platform and support legs. In the front view, the area above the equipment mounting platform is the upper part of the frame, and the area below the equipment mounting platform is the lower part. The left side of the frame in the front view is the left side, and the right side is the right side. Frame 12 serves as the mounting platform for all pipes, valves, and equipment. It can be fixed inside the sludge treatment vehicle and connected to the sludge dewatering equipment inside.
[0026] The feed pipe section 1, three-way valve 13, drain pipe 2, discrete pipe 3, double Venturi jet siphon 4, spiral pipe 5, drainage pipe 6, gas collection device 7, and ammonia nitrogen gas sensor 8 are sequentially connected and fixed as a whole, and fixed below the frame. The ozone generator 11, deodorant storage tank 10, and control cabinet are sequentially installed above the frame. The ozone generator 11 is connected to the first siphon port 4-5 on the double Venturi jet siphon 4 through the ozone delivery pipe 16. The deodorant storage tank 10 is connected to the second siphon port 4-7 on the double Venturi jet siphon 4 through the agent delivery pipe 15. A agent flow control valve 14 is installed in the middle section of the agent delivery pipe to control the amount of deodorant delivered. An ammonia nitrogen sensor 8 is installed inside the gas collection device 7. The gas collection end of the sensor is installed inside the gas collection device, and the signal transmission end is exposed outside the gas collection device 7. It is fixed to the gas collection device by the sensor's own flange. The ammonia nitrogen sensor 8 is connected to the control cabinet 9 through control lines.
[0027] Sludge from the manhole enters a three-way valve 13 via a suction pump from the inlet pipe section 1. The three-way valve 13 connects to a discrete pipe 3 and a drain pipe 2. Under normal loading conditions, the three-way valve 13 remains directly connected to the discrete pipe 3. After the sludge enters the discrete pipe 3, the sludge jet is divided by a discrete device 3-2 installed inside the pipe, splitting the single jet into multiple jets and releasing the gas in the sludge. The sludge jet with released gas passes through a double Venturi jet siphon 4, where it mixes with ozone and a deodorant. The ozone gas is generated by an ozone generator 11, and the deodorant is a liquid agent stored in a deodorant storage tank 10. The two substances pass through the two suction ports of the double Venturi jet siphon 4. The first siphon port 4-5 and the second siphon port 4-7 enter the pipe sequentially. The slurry jet mixed with ozone and deodorant continues to be transported forward into the pipe and enters the spiral tube 5. Four spiral blades 5-3 are arranged at intervals inside the spiral tube 5. When the jet comes into contact with the spiral blades 5-3, the jet rotates under the guidance of the spiral blades 5-3. This can further promote the rotational friction of the slurry mixed with ozone and deodorant under the action of rotation and interval distance. This allows the jet to further release the entrained gas and further decompose the ozone gas in the pipe and further fuse with the deodorant solution to suppress other harmful gases carried in the slurry. After passing through the spiral tube 5, the jet enters the drainage pipe 6. The drainage pipe 6 is connected to the gas collection device 7. The top of the gas collection device 7 has an ammonia nitrogen gas sensor 8 built in. The bottom of the gas collection device 7 is a rectangular open opening for docking with the slurry mixing tank in the ditch sludge treatment vehicle.
[0028] With atmospheric connectivity, when the mud flows out from the bottom of the gas collection device, air exchange and flow will occur inside the box. The shielding plate 7-4 inside the box will guide the airflow generated by the mud jet hitting the inner wall of the box to the gas collection chamber at the top of the device, so that the sensor can collect the ammonia nitrogen gas concentration data when the mud leaves the tube.
[0029] Based on the signal fed back by the ammonia nitrogen sensor 8, the control cabinet 9 controls the deodorant interception control valve 14, the three-way valve 13, and the ozone generator 11. When no ammonia nitrogen gas is discharged from the sludge in the pipeline through the discharge port or when the gas level is lower than the set hazard value, the control cabinet 9 does not start the ozone generator 11 and the deodorant interception control valve 14. The three-way valve 13 is in a straight-through state with the main pipeline, and the deodorant interception control valve 14 is in a closed state.
[0030] When the ammonia nitrogen sensor 8 in the gas collection device 7 senses the ammonia nitrogen gas carried in the slurry discharged from the pipeline and the value reaches the set hazard value, the control cabinet starts the ozone generator 11 and opens the deodorant interception control valve 14. Through the double Venturi jet siphon tube 4, ozone and deodorant are drawn into the pipeline during the slurry transportation process using the Venturi vacuum siphon effect. The mixture and deodorant are then mixed, dissolved, and drained through the spiral tube 5 and the drainage tube 6. The gas collection device 7 continuously collects the gas emission concentration signal of the discharged slurry and controls the deodorant interception control valve 14. The valve size of the deodorant interception control valve 14 is adjusted according to the change in gas concentration.
[0031] When the ammonia nitrogen sensor 8 in the gas collection device 7 detects that the ammonia nitrogen gas carried by the discharged sludge exceeds the warning concentration, the control cabinet 9 can control the three-way valve 13 at the inlet of the main pipeline to divert and limit the flow of sludge entering the main pipeline. This ensures that the sludge carrying high concentrations of hazardous gases does not exceed the gas production capacity of the ozone generator and the deodorizing agent delivery capacity, thereby decomposing the gases carried by the sludge in the pipeline and ensuring the safety of vehicles and workers.
[0032] like Figure 2 As shown, the discrete pipe 3 includes a flange 3-1, a discrete device 3-2, and a mud pipe 3-3. There are two flanges 3-1, which are welded to both ends of the mud pipe 3-3 respectively. The discrete device 3-2 is welded inside the mud pipe 3-3 near the mud input direction, at 1 / 4 of the length of the mud pipe. The discrete device 3-2 is a circular steel plate cut according to the inner diameter of the mud pipe. The steel plate has a matrix structure with closely arranged annular holes. The function of these holes is to divide the single mud jet entering the pipe and release harmful gases such as ammonia nitrogen carried in the mud.
[0033] like Figure 4As shown, the dual Venturi jet siphon 4 includes an inlet flange 4-1, a front overflow pipe 4-2, an inner constriction pipe 1 4-3, an inner constriction pipe 2 4-4, a siphon port connector 1 4-5, a sleeve 4-6, a siphon port connector 2 4-7, a jet throat 4-8, a diffuser 4-9, and an outlet flange 4-10. The inlet flange 4-1 is welded to the front overflow pipe 4-2 as a single unit. The outlet end of the inner wall of the pipe is welded to the large-diameter end of the inner constriction pipe 1 4-3, with approximately half of the large diameter of the inner constriction pipe 1 4-3 protruding externally. Both the inner constriction pipe 1 4-3 and the inner constriction pipe 2 4-4 are sections with varying diameters, with the large diameter being 1.25 times the small diameter. Ozone and deodorant inlets are opened on the sleeve 4-6 according to the calculated delivery volume, with holes spaced at certain intervals. Welds are then applied to the openings. Connect siphon connector 1 4-5 (ozone pipe connector) and siphon connector 2 4-7 (deodorant pipe connector). The inner shrink tube 2 4-4 is prefabricated and welded inside the sleeve 4-6. Its large diameter is located between the ozone inlet and the deodorant inlet. After the inner shrink tube 2 is welded, the inlet end of the sleeve 4-6 is inserted into the inner shrink tube 1 4-5 and welded to the front overflow pipe 4-2 to form a whole. The outlet end of the sleeve 4-6 is inserted and welded to the jet throat 4-8. The jet throat 4-8 is also a pipe with a diameter change. Its diameter change angle is smaller than that of the inner shrink tubes 1 and 2 and its small diameter is longer. The large diameter of the jet throat 4-8 is inserted and welded to the outlet end of the sleeve 4-6, and the small diameter end is inserted and welded to the inlet end of the diffuser 4-9. The diffuser 4-9 is a horn-shaped diameter change pipe. Its outlet end is welded to the outlet flange 4-10.
[0034] like Figure 5 As shown, the spiral pipe 5 includes a flange 5-1, a mud pipe 5-2, and spiral blades 5-3.
[0035] There are two flanges 5-1, which are welded to both ends of the mud pipe 5-2 respectively. There are four spiral blades 5-3, which are evenly distributed and welded inside the mud pipe 5-2 at certain intervals.
[0036] like Figures 5-6 As shown, the gas collection device 7 includes an inlet pipe 7-1, a gas collection box 7-2, a mud guide plate 7-3, a shielding plate 7-4, and an upper cover plate 7-5.
[0037] The feed pipe 7-1 with a flange is welded to the gas collection box 7-2. The gas collection box 7-2 is an irregularly shaped double-sided open box. The top of the box is a cover plate 7-5 connected by bolts, and the bottom is an opening. The box is sealed with plates on all four sides. The side connected to the feed pipe 7-1 has an opening and is welded to the feed pipe 7-1. The cover plate 7-5 has two small round holes. The central round hole is used to install the ammonia nitrogen gas sensor 8, and the other round hole is used for gas exchange, which is beneficial for the collection of gas off the pipe.
[0038] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
