Description

Technical Field

[0001] The invention belongs to the technical field of rubber hose vulcanization waste gas emission, and in particular relates to a linkage-controlled rubber hose high-temperature steam shaping waste gas emission control system. Background Art

[0002] During the hose vulcanization process, the rubber raw materials undergo a cross-linking reaction under high temperature and high pressure, releasing a large amount of smoke containing volatile organic compounds (VOCs), hydrogen sulfide, sulfur dioxide and other harmful gases.

[0003] The current smoke exhaust method for hose vulcanization relies on a simple door-opening strategy, which has exposed many drawbacks in practice, especially in the post-vulcanization area. The original design for this area relied solely on a single, always-on exhaust fan at the door for exhaust. However, this exhaust method proved inadequate for complex smoke emission scenarios.

[0004] First, the direct consequence of opening the door to exhaust smoke is the uncontrolled spread of smoke. When the door is open, smoke spreads rapidly in all directions, polluting the surrounding air and posing a potential threat to worker health. Because smoke cannot be effectively captured and discharged by the door's fans, a large amount of smoke remains in the work area, seriously affecting the cleanliness of the production environment and operational safety.

[0005] Secondly, the open exhaust design resulted in an excessively large air outlet area, which to some extent exacerbated the difficulty of exhaust. To cope with the large exhaust area, higher-power fans had to be used. However, operating high-power fans not only meant higher energy consumption but also brought with it additional issues such as noise and vibration, causing secondary disruption to the production environment. More critically, despite the increased fan power, exhaust effectiveness did not significantly improve, and the energy-to-performance ratio actually decreased, creating a dual dilemma of wasted resources and low efficiency. Summary of the Invention

[0006] The purpose of the present invention is to solve the problem that the current hose vulcanization smoke exhaust adopts a simple door-opening method, which causes the smoke to spread everywhere and cannot be completely collected by the fan at the door. At the same time, due to the open smoke exhaust, the air outlet area is too large and the fan selection power is high, resulting in a poor energy-to-effect ratio. A linkage-controlled hose high-temperature steam curing waste gas emission control system is proposed.

[0007] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solution: a linkage-controlled high-temperature steam shaping exhaust gas emission control system for hoses, comprising:

[0008] Closed smoke exhaust cavity: A closed smoke exhaust cavity is set around the hose vulcanization equipment. The closed smoke exhaust cavity completely surrounds the hose vulcanization area, and only adjustable smoke exhaust ports are set at the top of the cavity or at specific locations to limit the range of smoke diffusion;

[0009] Intelligent smoke exhaust device: includes at least one variable power exhaust fan, the exhaust fan is connected to the exhaust port of the closed smoke exhaust cavity, and the exhaust fan is equipped with a variable frequency controller for dynamically adjusting the fan power according to the actual smoke exhaust demand;

[0010] Smoke concentration monitoring system: at least one smoke concentration sensor is provided in the closed smoke exhaust cavity to monitor the smoke concentration in the cavity in real time;

[0011] Linkage control system: The linkage control system is respectively connected to the smoke concentration monitoring system and the intelligent smoke exhaust device by signal. The linkage control system receives the smoke concentration data transmitted by the smoke concentration sensor and automatically controls the opening and closing and power adjustment of the exhaust fan according to the preset smoke concentration threshold, thereby realizing intelligent linkage control of the smoke exhaust process and the amount of smoke generated;

[0012] Hose vulcanizing equipment interface module: The hose vulcanizing equipment interface module is connected to the main control system of the hose vulcanizing equipment and is used to receive the working status signal of the hose vulcanizing equipment. When the hose vulcanizing equipment is started, the linkage control system can receive the start signal and make smoke exhaust preparations in advance;

[0013] And safety protection module: including an emergency smoke exhaust channel and a matching emergency opening device arranged on the closed smoke exhaust cavity. The emergency smoke exhaust channel is automatically or manually opened when the conventional smoke exhaust system fails or the smoke concentration exceeds the safety threshold to ensure smoke exhaust safety.

[0014] As a further description of the above technical solution:

[0015] The closed smoke exhaust cavity adopts a detachable structure, which is convenient for maintenance and repair of the hose vulcanizing equipment, and the inner wall of the closed smoke exhaust cavity is made of stainless steel or nickel-based alloy material.

[0016] As a further description of the above technical solution:

[0017] The variable power exhaust fan is a centrifugal fan. The variable frequency controller adopts a closed-loop control algorithm to accurately adjust the fan speed according to the real-time data feedback from the smoke concentration sensor to achieve the best smoke exhaust effect and energy utilization efficiency. The formula of the closed-loop control algorithm is:

[0018]

[0019] Among them, Δv is the fan speed adjustment, K p , K i , K d are proportional, integral and differential control parameters respectively, C target is the preset smoke concentration threshold, C current is the current smoke density.

[0020] As a further description of the above technical solution:

[0021] The smoke concentration monitoring system also includes a data recording and analysis module for recording historical smoke concentration data and providing a basis for optimizing the smoke exhaust strategy through data analysis. The preset smoke concentration threshold C target It can be calculated using the following formula based on historical data:

[0022] C target =μ+kσ; where μ is the average value of historical smoke concentration, σ is the standard deviation of historical smoke concentration, and k is the safety factor, ranging from 1.5 to 3.

[0023] As a further description of the above technical solution:

[0024] The linkage control system is also equipped with a remote monitoring and operation interface, allowing operators to remotely monitor the status of the smoke exhaust system through the network and perform necessary parameter adjustments and control operations.

[0025] As a further description of the above technical solution:

[0026] The emergency smoke exhaust channel is equipped with an automatic sensing device, which automatically triggers the emergency smoke exhaust program when it detects that the smoke concentration exceeds the preset safety threshold, and sends an alarm message to the operator at the same time; the safety threshold C safe for:

[0027] C safe =C target +ΔC, ΔC is the safety margin, and its value range is C target 10% to 20% of.
