Description

Technical Field

[0001] This utility model relates to a waste gas treatment device, and more particularly to a waste gas treatment device for rubber vulcanization. Background Technology

[0002] The development of waste gas treatment equipment for rubber vulcanization stems from the fact that the waste gas generated in rubber product vulcanization workshops contains pollutants such as volatile organic compounds (VOCs), hydrogen sulfide (H2S), benzene compounds, and particulate matter. Its complex composition and pungent odor mean that direct emissions would severely pollute the environment and harm human health. With the strict enforcement of environmental regulations such as the "Emission Standard for Pollutants from Rubber Products Industry," traditional treatment methods, such as wet treatment processes (e.g., spray towers), suffer from secondary wastewater pollution. Activated carbon adsorption systems require frequent maintenance and are costly, while combustion catalysis methods are energy-intensive. None of these methods meet the demand for efficient treatment. Utility Model Content

[0003] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a rubber vulcanization waste gas treatment device.

[0004] The technical solution is as follows: A rubber vulcanization waste gas treatment device includes a conical separation cylinder, an inlet pipe, a guide strip, an exhaust pipe, a condenser, a central connecting pipe, and a catalytic converter. The lower part of the conical separation cylinder has an inlet pipe, and the cylinder has an airflow cavity. The inlet end of the inlet pipe is located at the tangent of the lower part of the cylinder wall. A guide strip is annularly arranged on the inner wall of the conical separation cylinder, guiding the airflow in a spiral motion towards the upper part of the cylinder. An exhaust pipe is located at the top of the conical separation cylinder, communicating with the interior of the cylinder. The end of the exhaust pipe is connected to a condenser. A central connecting pipe is located at the lower part of the condenser, and the end of the central connecting pipe is connected to a catalytic converter. A drain pipe is located on the catalytic converter. A slag discharge device is located at the lower part of the conical separation cylinder, through which particulate impurities inside the conical separation cylinder are discharged.

[0005] Preferably, the slag discharge component includes a slag discharge pipe, a valve, and a collection box. The lower part of the conical separation cylinder is provided with a slag discharge pipe, which is connected to the internal space of the conical separation cylinder. A valve is provided on the slag discharge pipe, and a collection box is provided at the lower end of the slag discharge pipe.

[0006] Preferably, the conical separator is inclined.

[0007] Preferably, the upper center of the conical separator is provided with a downward-pointing hemispherical protrusion.

[0008] Preferably, the system also includes a filter box, an oil receiving tank, grooved plates, and baffles. The filter box is installed on the exhaust pipe. The filter box contains multiple grooved plates, which divide the interior of the filter box into multiple horizontally arranged spaces. The grooved plates have several slots. There is a gap between the bottom of the grooved plates and the bottom of the filter box. Several baffles are arranged between adjacent grooved plates. Each baffle has a protrusion, and an airflow channel is formed between two adjacent baffles. The protrusions extend into the airflow channel. The lower part of the filter box is connected to an oil receiving tank, which is connected to the lower space inside the filter box through a pipe.

[0009] Preferably, a pressure pump is also included, with the pressure pump installed on the pipeline of the central connecting pipe.

[0010] The beneficial effects of this utility model are as follows: 1. This utility model achieves dry separation of particulate matter in waste gas through a conical separation cylinder, which completely avoids the problems of secondary pollution and maintenance difficulties in traditional processes; the waste gas is treated by integrated condensation and catalysis, which efficiently removes volatile organic compounds and sulfur-containing pollutants, while using reaction heat energy to reduce system energy consumption.

[0011] 2. This utility model has a downward-pointing hemispherical protrusion at the upper exhaust pipe inside the conical cylinder. The arc-shaped lower convex surface changes the airflow direction and slows down the flow rate, allowing particulate impurities to settle naturally due to inertia. This effectively prevents impurities from being carried out directly by the airflow, improves the fineness of exhaust gas purification, and reduces the risk of subsequent pipe blockage.

[0012] 3. By adding a filter box to the exhaust pipe of the conical separator, this utility model not only efficiently intercepts the residual oil mist in the exhaust gas, but also further captures fine oil droplets and aerosol particles through its unique layered filtration structure, thus completely avoiding the problem of oil mist adhering to, polluting and corroding the subsequent condensation pipes and the inside of the catalytic converter.

Detailed Implementation

[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0019] Example 1

[0020] A rubber vulcanization waste gas treatment device, such as Figure 1-4 As shown, the device includes a conical separator 1, an intake pipe 2, a guide strip 21, an exhaust pipe 3, a condenser 4, a central pipe 5, and a catalytic converter 6. The conical separator 1 is inclined, with an intake pipe 2 located in its lower part. The intake end of the intake pipe 2 is located at the tangent of the lower part of the conical separator 1. This arrangement allows the incoming gas to enter the conical separator 1 along the tangent of the cylinder wall, forming a rotating airflow. The conical separator 1 has an airflow cavity, and a guide strip 21 is arranged in a ring on the inner wall. The guide strip 21 guides the airflow to flow spirally towards the upper part of the conical separator 1. During the spiral ascent, the particulate impurities in the gas will gradually approach the inner wall of the conical separator 1 and settle downwards due to gravity and centrifugal force, thereby achieving preliminary particle separation.

[0021] The upper center of the conical separator 1 is provided with a downward-pointing hemispherical protrusion 22. The lower convex surface of the hemispherical protrusion 22 can further change the flow direction and velocity distribution of the airflow, so that the airflow is disturbed and decelerated when passing through the lower convex surface. Due to inertia, particulate impurities are less likely to continue to move upward with the airflow, thereby further preventing particulate impurities from being discharged from the exhaust pipe 3 with the airflow, and greatly improving the particle separation effect.

[0022] The conical separator 1 is inclined. When the waste gas entering the cylinder forms a rotating airflow along the tangential direction of the cylinder wall, the inclined angle can better guide the particulate impurities to settle quickly and thoroughly to the bottom of the cylinder under the dual action of gravity and centrifugal force, effectively avoiding the disorderly accumulation of particulate impurities in the cylinder. At the same time, the inclined structure can also promote the natural convergence of the settled impurities to the slag discharge area.

[0023] The top of the conical separator 1 is equipped with an exhaust pipe 3, which is connected to the interior of the conical separator 1. The gas after preliminary particle separation is discharged from the exhaust pipe 3. The end of the exhaust pipe 3 is connected to a condenser 4. After the gas enters the condenser 4, the condensable components such as oil mist will condense into liquid at low temperature, thereby achieving preliminary separation of oil mist. The lower part of the condenser 4 is equipped with a middle pipe 5, and the end of the middle pipe 5 is connected to a catalytic converter 6. The gas after condensation enters the catalytic converter 6 through the middle pipe 5. In the catalytic converter 6, the harmful substances in the gas will undergo a chemical reaction under the action of the catalyst and be converted into harmless substances. Finally, the gas is discharged through the drain pipe on the catalytic converter 6.

[0024] like Figure 1 As shown, the lower part of the conical separator 1 is equipped with a slag discharge component, which includes a slag discharge pipe 23, a valve 24, and a collection box 25. The lower part of the conical separator 1 is connected to the slag discharge pipe 23, and the valve 24 is installed on the slag discharge pipe 23. The collection box 25 is installed at the lower end of the slag discharge pipe 23. When a certain amount of particulate impurities accumulate at the lower part of the conical separator, the valve 24 is opened, and the particulate impurities will fall into the collection box 25 through the slag discharge pipe 23 under the action of gravity, which facilitates the centralized cleaning of particulate impurities and ensures the continuous and efficient operation of the conical separator 1.

[0025] Example 2

[0026] Based on Example 1, such as Figure 1 , Figure 3 and Figure 4As shown, it also includes a filter box 7, an oil receiving tank 71, a grooved plate 72, and a baffle plate 73. The filter box 7 is installed on the exhaust pipe 3. The filter box 7 has multiple grooved plates 72 inside, which divide the interior of the filter box 7 into multiple horizontally arranged spaces. This partitioning design can prolong the residence time of the airflow in the filter box 7 and improve the filtration effect. The grooved plate 72 has several slots, and there is a gap between the bottom of the grooved plate 72 and the bottom of the filter box 7. This gap allows the oil mist to drip off under the action of gravity, preventing the oil mist from accumulating on the grooved plate 72 and affecting the filtration efficiency. Several baffles 73 are arranged between adjacent slotted plates 72. Each baffle 73 has a protrusion, and an airflow channel is formed between two adjacent baffles 73. The protrusions extend into the airflow channel, and there is an airflow gap between the end of each protrusion and the adjacent baffle. When the airflow enters the airflow channel from right to left through the slots of the slotted plates 72, the protrusions change the direction and speed of the airflow, causing turbulence. This makes it easier for the oil mist in the exhaust gas to collide with the baffles 73 and adhere to their surfaces, thereby achieving effective separation of the oil mist. The airflow sequentially passes through multiple slotted plates 72 and the airflow... As the airflow passes through the channel, it flows to the right along the gaps in the airflow and finally exits from the slot of the rightmost slotted plate 72. It then enters the exhaust pipe 3 connected to the condenser 4. The lower part of the filter box 7 is connected to an oil receiving tank 71, which is connected to the lower space inside the filter box 7 through a pipe. In this way, the oil mist dripping from the slotted plate 72 and the baffle plate 73 will flow into the oil receiving tank 71 through the pipe, which facilitates the collection and treatment of the separated oil mist, avoids the pollution of the environment by the oil mist, and also reduces the impact of the oil mist on the subsequent equipment, thereby improving the stability and reliability of the entire exhaust gas treatment device.

[0027] like Figure 1 As shown, it also includes a pressurizing pump 51. The pressurizing pump 51 is installed on the pipeline of the intermediate connecting pipe 5. The setting of the pressurizing pump 51 can provide additional power for the gas after condensation treatment, so that the gas can enter the catalytic machine 6 more smoothly through the intermediate connecting pipe 5. Since the catalytic reaction needs to be carried out under a certain airflow speed and pressure, the pressurizing pump 51 can ensure that the gas enters the catalytic machine 6 at a suitable flow rate and pressure, thereby improving the efficiency and effect of the catalytic reaction, ensuring that the harmful substances in the waste gas can be more fully converted into harmless substances, and further improving the purification capacity of the entire waste gas treatment device.

Any equivalent structural or procedural transformations made using the content of this utility model specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
