AI Technical Summary
Existing asphalt fume incinerators have difficulty draining oil from the bottom during operation, posing a safety hazard. In particular, under negative pressure conditions, the drain outlet is prone to backflow, preventing the oil from being effectively discharged.
A box-type structure is installed at the bottom of the incinerator body, equipped with a collection plate and a liquid guide column. The liquid guide channel guides the oil, and the oil is collected through the liquid hopper and discharged through the oil outlet. Combined with a liquid baffle ring, the oil is prevented from flowing back.
It effectively prevents oil accumulation, increases the rate of oil coagulation and dripping, simplifies the oil discharge process, and ensures safety.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of regenerative thermal incinerator technology, and in particular to a regenerative thermal incinerator that prevents oil accumulation. Background Technology
[0002] Existing asphalt fume incinerators accumulate oil at the bottom during asphalt combustion, posing a safety hazard. Current regenerative thermal pyrolysis incinerators for asphalt fume typically have three channels at the bottom: an inlet channel, an outlet channel, and a middle channel. All three channels are horizontal, making it difficult to position the drain outlet at the lowest point. This results in incomplete oil discharge. Furthermore, the drain outlet in the middle channel must be routed from the center of the unit, resulting in a long drain pipe that hinders proper drainage. When the incinerator is designed for negative pressure operation, opening the drain outlet at the bottom allows outside air to be drawn into the unit due to the high-volume airflow from the fan, preventing oil from draining and causing backflow into the unit. Utility Model Content
[0003] The purpose of this invention is to address the shortcomings of existing technologies, such as the inconvenience of draining oil from inside the incinerator, and to propose a regenerative incinerator that prevents oil accumulation.
[0004] To achieve the above objectives, the present invention adopts the following technical solution:
[0005] Design a regenerative thermal oxidizer to prevent oil accumulation, comprising an oxidizer body, a box-shaped structure installed at the bottom of the oxidizer body, an air inlet and an air outlet installed on opposite sides of the box-shaped structure, a collection plate installed at the junction of the top of the box-shaped structure and the oxidizer body, the structural dimensions of the collection plate matching the cross-sectional structural dimensions of the box-shaped structure, the collection plate being a metal mesh plate, a first liquid guiding column installed in the middle of the collection plate, and multiple second liquid guiding columns evenly installed circumferentially on the outer side of the collection plate, a liquid hopper installed at the bottom of the box-shaped structure, and an oil outlet installed at the bottom of the liquid hopper.
[0006] Preferably, a liquid-retaining ring is installed inside the liquid-collecting hopper, and the liquid-retaining ring is located above the oil outlet.
[0007] Preferably, the first liquid guiding column has a plurality of first liquid guiding grooves evenly distributed along the circumference, and the second liquid guiding column has a plurality of second liquid guiding grooves evenly distributed along the circumference.
[0008] Preferably, a reinforcing ring is installed inside the collecting plate, and the position of the reinforcing ring corresponds to the position of the second liquid guiding column.
[0009] Preferably, both the second liquid guiding column and the first liquid guiding column are conical columns, and the tips of both the first liquid guiding column and the second liquid guiding column face downwards.
[0010] The present invention proposes a regenerative incinerator for preventing oil accumulation, which has the following advantages: the first and second liquid guiding columns are installed by a collection plate mounted on a box at the bottom of the incinerator body, which facilitates the condensation and flow of oil. At the same time, the liquid collection hopper is used to collect the oil, which facilitates the discharge of the oil and prevents the oil from accumulating and becoming difficult to discharge.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Example
[0016] Reference Figure 1-3A regenerative thermal oxidizer with oil accumulation prevention includes an oxidizer body 1. A box-type incinerator 7 is installed at the bottom of the oxidizer body 1. An air inlet 2 and an air outlet 3 are respectively installed on opposite sides of the box-type incinerator 7. A collection plate 6 is installed at the top of the box-type incinerator 7 where it connects with the oxidizer body 1. The structural dimensions of the collection plate 6 match the cross-sectional dimensions of the box-type incinerator 7. The collection plate 6 is a metal mesh plate. A first liquid guiding column 8 is installed in the middle of the collection plate 6, and multiple second liquid guiding columns 9 are evenly installed circumferentially on the outer side of the collection plate 6. A reinforcing ring 11 is installed inside the collection plate 6. The position corresponds to the position of the second liquid guiding column 9, which improves the installation stability of the second liquid guiding column 9 and can improve the coagulation efficiency of the second liquid guiding column 9 for oil. A liquid holding hopper 5 is installed at the bottom of the box 7, and an oil outlet 4 is installed at the bottom of the liquid holding hopper 5. A liquid baffle ring 12 is installed inside the liquid holding hopper 5, and the liquid baffle ring 12 is located above the oil outlet 4. Multiple first liquid guiding grooves 13 are evenly opened in the circumference of the first liquid guiding column 8, and multiple second liquid guiding grooves 10 are evenly opened in the circumference of the second liquid guiding column 9 to prevent the oil from flowing with the wind and improve the coagulation and dripping efficiency of the oil.
[0017] Working principle: The first liquid guiding column 8 and the second liquid guiding column 9 installed on the collection plate 6 installed between the incinerator body 1 and the box 7 complete the condensation and dripping of the oil. The opening of the first liquid guiding groove 13 and the second liquid guiding groove 12 increases the dripping rate of the oil. The liquid baffle ring 12 installed inside the liquid hopper 5 prevents the collected oil from flowing, which facilitates the discharge of the oil and prevents the oil from accumulating inside the incinerator body 1. Example
[0018] Reference Figure 1-2 As another preferred embodiment of this utility model, the difference from embodiment 1 is that the second liquid guiding column 9 and the first liquid guiding column 8 are both conical columns, and the tips of the first liquid guiding column 8 and the second liquid guiding column 9 are both pointing downwards, which facilitates the coagulation and dripping of the oil, prevents the accumulation of oil inside the incinerator, and is simple to operate and has high oil removal efficiency.
[0019] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
