Description

Technical Field

[0001] The utility model relates to an exhaust gas collection device for resin reactor production. Background Art

[0002] Resins are divided into natural resins and synthetic resins. Natural resins refer to amorphous organic substances obtained from secretions of animals and plants in nature, such as rosin, amber, shellac, etc. Synthetic resins refer to resin products obtained by chemical synthesis of simple organic substances or by chemical reactions of certain natural products, such as phenolic resin, polyvinyl chloride resin, etc. Among them, synthetic resin is the main component of plastics. Resin usually refers to an organic polymer that has a softening or melting range when heated, has a tendency to flow under the action of external force when softened, and is solid, semi-solid, or sometimes liquid at normal temperature.

[0003] In addition, resins have a certain volatility. During the resin production process, a large amount of exhaust gas is generated, the smell of which will affect human health, and direct emission into the air is likely to cause air pollution.

[0004] In existing large-scale production, generally, after the equipment generated by multiple reaction kettles is sucked through a negative pressure system, centralized treatment is carried out. However, when the production batch is small, if the entire negative pressure system is directly used for suction, the energy consumption is large, which is not conducive to the current concept of environmental protection and energy conservation.

During use, the exhaust gas in the reaction kettle is directly sucked by the exhaust gas recovery device through the exhaust gas outlet on the resin reaction kettle, and at the same time, the suction mechanism sucks the gas at the output end of the discharge pipeline to achieve comprehensive exhaust gas suction.

[0024] In this embodiment, for reasonable design, the waste gas recovery device includes a fixed seat 6. An primary filtration mechanism 7 and a secondary recovery mechanism 8 are installed on the fixed seat. The fixed seat is fixed on the lid of the resin reaction kettle. A connection hole 9 penetrating the fixed seat is provided on the fixed seat. The connection hole is communicated with the waste gas outlet. The other end of the connection hole is connected to the input end of the primary filtration mechanism. The output end of the primary filtration mechanism is connected to the input end of the secondary recovery mechanism. During use, the primary filtration mechanism filters impurities at the bottom of the waste gas, and the secondary recovery mechanism recovers the filtered waste gas.

[0025] In this embodiment, the specific structure of the primary filtration mechanism is as follows: The primary filtration mechanism includes a filter 10. The filter includes a horizontally arranged filter housing 11. A filtration chamber 12 is arranged inside the filter housing. A plurality of vertical sockets 13 communicating with the filtration chamber are arranged at intervals on the side wall of the filter housing along the waste gas flow direction. A filter plate 14 is inserted into the vertical socket. The filter plate can be an existing filter box with filter particles. Activated carbon particles can be selected as the filter particles. The filter plate can be quickly replaced through the plug-and-play filter plate. For reasonable design, a filtration inlet 15 communicating with the filtration chamber is provided at one end of the filter housing, and a filtration outlet 16 communicating with the filtration chamber is provided at the other end of the filter housing. The filtration outlet is connected to the input end of the secondary recovery mechanism through a pipeline, and the filtration inlet is connected to the connection hole through a pipeline.

[0026] In this embodiment, in order to more specifically realize the plugging and unplugging of the filter plate, slots 17 are symmetrically arranged on the upper and lower sides of the filter housing corresponding to the vertical sockets. The filter plate is slidably connected between the upper and lower two slots.

[0027] In this embodiment, the secondary recovery mechanism includes a recovery tank 18. The recovery tank is installed on the fixed seat. A tank cover 19 is provided on the opening of the recovery tank. A component recovery liquid 20 is contained in the recovery tank. An air inlet hole 21 is provided on the tank cover. The pipeline on the filtration outlet extends into the recovery tank through the air inlet hole and enters the component recovery liquid. An air outlet hole 22 is provided on the tank cover. The air outlet hole is connected through a pipeline. The component recovery liquid is an existing technology. Those skilled in the art select it according to the volatiles of different components of the resin. The waste gas output from the filtration outlet is directly introduced into the component recovery liquid. After sufficient contact, the purification is completed and it floats and discharges.

[0028] In this embodiment, in order to specifically realize suction, an air extractor 23 is installed on the filtration outlet. The input port of the air extractor is connected to the filtration outlet, and the output port of the air extractor is connected to the recovery tank through a pipeline, that is, the pipeline at the output port of the air extractor extends into the recovery tank through the air inlet hole and enters the component recovery liquid.

The other end of the air suction pipe is connected to a corrugated pipe 25. A flared mouth 26 is provided at the other end of the corrugated pipe. A drip trough 27 is connected to the flared mouth. More specifically, the drip trough includes a flared outer wall. Annular plates are provided at both the large mouth and the small mouth of the flared outer wall. The two annular plates and the flared outer wall form an annular groove. The small mouth of the flared mouth is connected to the corrugated pipe. An annular connecting plate is provided at the edge of the large mouth of the flared mouth. The annular connecting plate is connected to the inner side of the annular plate at one end of the small mouth of the drip trough. By directly connecting the annular groove outside the flared mouth, it is convenient to always flow the waste liquid along the pipeline into the annular groove for collection no matter how it is rotated and adjusted, effectively avoiding natural dripping or dripping into the material-containing container and causing pollution. After use, it can be removed and cleaned in time.
