Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of smoke leak detection systems, specifically a smoke leak detection system for large-volume environmental protection equipment. Background Technology
[0002] Leak detection for large-volume environmental protection equipment generally employs the following two methods:
[0003] The first method is the air-soap water test:
[0004] Technical principle: Compressed air is injected into the equipment, and soapy water is applied to suspected external areas to detect leaks by observing the bubbles.
[0005] Core defect: Corrosive contamination; soap residue can corrode metal surfaces, especially carbon steel components (such as heat exchangers) in catalytic combustion furnaces, posing a risk of intergranular corrosion.
[0006] The second method, based on the technical principle, involves a built-in smoke generator and pressure sensor, which determine the sealing performance by observing the smoke diffusion.
[0007] Key shortcomings: Existing smoke generators have two main drawbacks. First, the amount of smoke generated is insufficient, with a typical smoke generation rate of 50 m³ / min, which is only suitable for devices smaller than 1 m³, such as car engine blocks, and cannot create an effective concentration gradient in large spaces. Second, the pressure control is crude, using a fixed pressure threshold, such as 0.1 MPa, which can easily lead to overpressure damage to the equipment.
[0008] Therefore, there is an urgent need for a large-volume environmental protection equipment smoke leak detection system to solve the above problems. Utility Model Content

A regulating valve is connected to the left end of the industrial gas source, and a pressure sensor is connected to the upper left side of the environmental protection device.
[0012] Preferably, the smoke oil in the smoke generator is vaporized by the heating rod and then rapidly sprayed out as smoke particles through the nozzle.
[0013] Preferably, the smoke generator is a high-flow-rate smoke generator, which has a 1500W titanium alloy heating rod and a 1L e-liquid capacity, and the smoke generation rate reaches 566m³ / min, which can fill a 100m³ space within 3 minutes.
[0014] Preferably, the environmental protection equipment is connected to a pressure sensor, and the smoke generator is controlled by a remote control. The smoke is then visualized using fluorescent smoke, which will show a yellow-green trail under ultraviolet light.

[0024] In the smoke generator 3, the e-liquid is vaporized by the heating rod and then quickly sprayed out as smoke particles through the nozzle.
[0025] I. Core Structure and Components of a Smoke Generator
[0026] 1. Main components
[0027] Liquid storage system: includes oil reservoir (oil can), top cover, and filling port;
[0028] Delivery system: miniature electromagnetic oil pump, oil pipeline;
[0029] Heating system: titanium-aluminum alloy heating rod (heating tube), thermostat, temperature fuse;
[0030] Control and display: control circuit board, remote control / wired control module, LED beads;
[0031] Smoke output and outer casing: nozzle, heat dissipation holes, handle, and housing.
[0032] II. Connection Relationships Between Components
[0033] 1. Oil storage tank and oil pump: The bottom of the oil storage tank is connected to the oil pump inlet via a silicone oil delivery pipe, and the oil pump outlet is connected to the heating chamber inlet via another silicone pipe.
[0034] 2. Heating chamber and nozzle: The outlet of the heating chamber is directly connected to the nozzle, and the vaporized smoke agent is sprayed out at high speed through the nozzle.
[0035] 3. Heating rod and control circuit: The heating rod, thermostat, and temperature fuse are all connected to the control circuit board via wires, and are powered and temperature controlled by the circuit.
[0036] 4. Control circuit and external components: The control circuit is connected to 220V AC mains power via a power cord, and a remote control / wired control interface is reserved to support remote start and stop operations.
[0037] III. Working Principle (Heating and Atomization Type)
[0038] 1. Filling and sealing: Open the top cover of the oil storage tank, inject 1L of fluorescent smoke agent through the funnel, and close the top cover to form a sealed space in the oil tank.
[0039] 2. Preheating stage: Turn on the power to the heating rod, and the control circuit supplies power to the heating rod. The heating rod quickly heats up to the preset temperature (about 200-400℃). The temperature controller monitors the temperature in real time and maintains a constant temperature.
[0040] 3. Delivery and atomization: After preheating, the control circuit starts the micro oil pump, which pumps the atomizer in the oil storage tank into the high-temperature heating chamber through the oil delivery pipe, where the atomizer is instantly heated and vaporized.
[0041] 4. Smoke production stage: The vaporized smoke agent is sprayed out through the nozzle under pressure and quickly condenses into fine particles upon contact with cold air, forming visible fluorescent smoke; at the same time, LED beads emit light synchronously, combining with the smoke to create special effects.
[0042] 5. Stop and Protection: When smoke stops, the oil pump stops working first, and the heating rod continues to maintain the temperature in standby mode; if the temperature rises abnormally, the thermal fuse will blow, cutting off the power supply to prevent damage to the equipment.
[0043] Among them, the smoke generator 3 is a high-flow smoke generator with a 1500W titanium alloy heating rod and a 1L e-liquid capacity, producing 566m³ / min of smoke, which can fill a 100m³ space in 3 minutes.
[0044] Among them, the environmental protection equipment 2 is connected to the pressure sensor 5, and the smoke generator is controlled by remote control to visualize the smoke. Fluorescent smoke is used, which will show a yellow-green trail under ultraviolet light, making it easier to identify the leak point.
[0045] The upper end of the environmental protection equipment 2 is sealed by the blocking plate 9.
[0046] Among them, the smoke generator 3 uses a smoke agent loading method. Open the top cover of the oil storage tank, inject 1L of fluorescent smoke agent through the funnel, close the top cover and start the heating rod for preheating.
[0047] It should be noted that the smoke generation and diffusion of this large-volume environmental protection equipment smoke leak detection system are optimized by using Bernoulli effect atomization technology. After the e-liquid is vaporized by the heating rod of the smoke generator 3, it is quickly sprayed out as smoke particles through the nozzle.
[0048] Equipment Connection and Preparation: Pressure Test. Connect the air inlet of the environmental protection equipment 2 to the environmental protection equipment under test through the quick-connect coupling. Start the industrial air source and inject compressed air into the environmental protection equipment to 0.03MPa. Continue for 5 minutes to perform a pre-test for air tightness.
[0049] Fluorescent agent loading: Initiation of filling: Open the top cover of the oil storage tank and add 1L of fluorescent smoke agent into the oil storage tank through the funnel; Sealing and closing: After filling, close the top cover of the oil storage tank to form a sealed filling chamber; Preheating start: Start the heating rod drive power supply to control the heating rod to preheat the fluorescent smoke agent in the oil storage tank and complete the preheating preparation.
[0050] Test Smoke Injection: Turn on the smoke generator 3. The smoke agent is heated and atomized at a fixed rate and injected into the environmental protection equipment under test through a hose, for example, the inner diameter of the hose is 25mm. At the same time, adjust the regulating valve 6 to maintain the pressure inside the environmental protection equipment at the set value.
[0051] Leakage location: Operators wearing night vision goggles with a wavelength of 400-700nm move and observe the surface of the environmental protection equipment. The fluorescent smoke leak point appears as a specific light spot, and the location accuracy reaches the visual level.
[0052] The contents not described in detail in this specification are existing technologies known to those skilled in the art.
[0053] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
