[0001] This utility model relates to the field of oil processing technology, and in particular to a waste gas recycling device for oil processing. Background Technology

[0002] In the oil processing industry, a series of core processes, from oilseed pretreatment, pressing, refining to deodorization, all generate a large amount of waste gas. Taking a medium-sized oil processing plant with a daily processing capacity of 500 tons of oilseeds as an example, the daily waste gas emissions from the deodorization process alone can reach 400-600 cubic meters. The temperature of these waste gases is usually in the range of 80-120℃, and their composition is complex.

[0003] Existing exhaust gases are usually directly emitted into the atmosphere, which easily pollutes the environment, and the large amount of heat energy in the high-temperature exhaust gases is easily wasted, thus causing energy waste. Utility Model Content

In this utility model, by opening the valve on the first conveying pipe, it is beneficial to facilitate the transport of exhaust steam to the interior of the heating tank through the first conveying pipe, which is beneficial to preheat the material inside the pre-softening pot, and to reuse the heat energy. Preheating the material inside the pre-softening pot in advance reduces steam costs.

However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0021] Example 1: As Figures 1-4 As shown, this utility model provides a technical solution: a waste gas recycling device for oil processing, including a processing component 1, a waste heat recycling component 2 and a condensation recycling component 3 connected to the side of the processing component 1, the processing component 1 including a softening pot 101, one end of the softening pot 101 being connected to a tail steam discharge pipe 103, and the other end of the softening pot 101 being connected to a steam inlet pipe 102, the waste heat recycling component 2 including a pre-softening pot 201, the side of the tail steam discharge pipe 103 being connected to a first conveying pipe 104, one end of the first conveying pipe 104 being provided with a heating tank 202, the outside of the heating tank 202 being provided with a heat insulation shell 203, the outside of the first conveying pipe 104 being provided with heat insulation cotton 205, valves being provided on both the second conveying pipe 105 and the first conveying pipe 104, the pre-softening pot 201 being provided with a feed inlet 204, and one end of the heating tank 202 being connected to a connecting pipe 206 and a discharge port 207.

[0022] In this embodiment, the steam inlet pipe 102 facilitates the entry of steam into the softening pot 101, and the exhaust steam inside the softening pot 101 is easily discharged through the exhaust steam discharge pipe 103. By opening the valve on the first conveying pipe 104, the exhaust steam is facilitated to be transported through the first conveying pipe 104 to the interior of the heating tank 202, which is beneficial for preheating the material inside the pre-softening pot 201, thus facilitating the reuse of thermal energy and reducing steam costs. Finally, the exhaust steam is transported to the subsequent processing equipment through the connecting pipe 206, avoiding direct emission of exhaust steam into the air and reducing air pollution. The insulation shell 203 provides insulation for the heat energy inside the heating tank 202, and the insulation cotton 205 provides insulation for the first conveying pipe 104, reducing heat loss and improving energy recovery efficiency.

[0023] Example 2: As Figures 1-4 As shown, the condensation reuse assembly 3 includes a recovery box 301, inside which a condenser 302 is installed. One end of the condenser 302 has a condensate inlet 303, and the other end of the condenser 302 has a condensate outlet 304. A second conveying pipe 105 is connected to the side of the exhaust pipe 103. One end of the second conveying pipe 105 is connected to the condenser 302.

[0024] In this embodiment, opening the valve on the second conveying pipe 105 facilitates the transport of exhaust gas through the second conveying pipe 105 to the interior of the condenser 302. The condensate inlet 303 facilitates the entry of condensate into the interior of the condenser 302, and the condensate outlet 304 facilitates the discharge of condensate, which helps to reduce the temperature of the exhaust gas. This causes the condensed liquid substances in the exhaust gas to be discharged through the outlet 305. Valuable components such as fatty acids can be separated from the liquid substances and used as chemical raw materials for the production of products such as soap and surfactants, realizing the recycling and reuse of resources in the waste gas. Finally, the exhaust gas is transported to the subsequent treatment equipment through the discharge pipe 306.

[0025] The working principle of this embodiment is as follows: During use, steam first enters the softening pot 101 through the steam inlet pipe 102. The exhaust steam inside the softening pot 101 is then easily discharged through the exhaust steam outlet pipe 103. Opening the valve on the first conveying pipe 104 facilitates the transport of the exhaust steam to the heating tank 202, enabling preheating of the material inside the pre-softening pot 201 and facilitating the reuse of thermal energy. Preheating the material inside the pre-softening pot 201 reduces steam costs. Opening the valve on the second conveying pipe 105... The valve facilitates the transport of exhaust gas through the second conveying pipe 105 to the interior of the condenser 302. The condensate inlet 303 facilitates the entry of condensate into the condenser 302, and the condensate outlet 304 facilitates the discharge of condensate, which helps to reduce the temperature of the exhaust gas. This allows the condensed liquid substances in the exhaust gas to be discharged through the outlet 305. Valuable components such as fatty acids can be separated from the liquid substances and used as chemical raw materials for the production of products such as soap and surfactants, realizing the recycling and reuse of resources in the waste gas. Finally, the exhaust gas is transported to the subsequent treatment equipment through the discharge pipe 306.
