Description

Technical Field

[0001] This application belongs to the field of exhaust gas treatment technology, specifically relating to an exhaust gas treatment system for pipelines prone to solidification and blockage. Background Technology

[0002] With the dwindling supply of oil and the environmental pollution and health hazards caused by petrochemical products during production and use, the country urgently needs to develop technologies for the comprehensive utilization of biorenewable resources. Utilizing soapberry, a byproduct of edible oil mills, to produce high-purity oleic acid, linoleic acid, palmitic acid, and other environmentally friendly products is widely recognized as an excellent alternative to petrochemical products and a scientific choice for the country to develop a low-carbon economy and prevent global environmental degradation. The comprehensive utilization of renewable bio-oil resources is of great significance to the sustainable development of my country's national economy.

[0003] During the production of acidified oil, the waste gas generated by acidification treatment includes sulfuric acid mist and water vapor. Condensing and recovering the water vapor in the waste gas is beneficial for subsequent absorption and treatment. However, the short-chain saturated fatty acids in the exhaust gas have a very high freezing point (greater than 10°C), which can easily cause pipeline blockage at room temperature. Utility Model Content

[0004] This application provides a pipeline gas treatment system for easy solidification and blockage of exhaust gas, in order to solve the above-mentioned technical problems.

[0005] To solve the above-mentioned technical problems, the technical solution adopted in this application is: a tail gas treatment system for easy solidification and blockage of pipelines, including: a tank, an outlet pipe and an inlet pipe, the outlet pipe being located at the top of the tank and inserted into the tank; an inlet pipe being provided on the side wall of the tank, a hopper being provided at the bottom of the tank, and a discharge port being provided at the lower end of the hopper; wherein, a steam pipe extending into the inside of the tank is provided on the inner wall of the inlet pipe.

[0006] Furthermore, the bottom of the exhaust pipe located inside the tank is lower than the lowest point of the intake pipe.

[0007] Furthermore, the steam pipe passes through the inside of the air inlet pipe and the inner wall of the tank, and extends from the bottom of the other side to the outside of the tank to connect to the bucket.

[0008] Furthermore, the bucket is equipped with an inlet pipe and an outlet pipe, wherein the steam pipe enters the bucket from the inlet pipe and exits from the outlet pipe.

[0009] Furthermore, the top of the tank and the side end of the gas outlet pipe are provided with a feeding port and a liquid inlet, and the outer wall of the tank is provided with a drain port.

[0010] Furthermore, a support plate is provided in the middle of the outer side of the tank.

[0011] The beneficial effects of this application are: This application adds a steam pipe to the exhaust gas inlet pipe and inside the tank, thereby controlling the exhaust gas and the inside of the tank periodically with steam through the DCS heating control system, heating the easily solidified short-chain saturated fatty acids in the exhaust gas into liquid, making them easy to collect, while preventing the short-chain saturated fatty acids in the exhaust gas from solidifying, thereby preventing the exhaust pipe from being blocked.

Detailed Implementation

[0013] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0014] like Figure 1-3 As shown, this application discloses a system for treating easily solidified and clogged exhaust gas, including: a tank 1, an outlet pipe 2, and an inlet pipe 3. The outlet pipe 2 is located at the top of the tank 1 and inserted into the tank 1; the inlet pipe 3 is provided on the side wall of the tank 1, and a hopper 4 is provided at the bottom of the tank 1, with a discharge port 41 at the lower end of the hopper 4; wherein, a steam pipe 5 extending into the tank 1 is provided on the inner wall of the inlet pipe 3. This application, by providing a heating steam pipe 5 in the exhaust gas inlet pipe 3, ensures that the inlet pipe 3 and the tank 1 are at a high temperature, thereby effectively preventing the solidification of short-chain saturated fatty acids in oily exhaust gas.

[0015] The bottom of the exhaust pipe 2 located inside the tank 1 is lower than the lowest point of the intake pipe 3. In the above design, the bottom of the exhaust pipe 2 is lower than the lowest point of the intake pipe 3, which ensures that the exhaust gas falls directly into the tank 1 for reaction and cannot be directly discharged from the exhaust pipe 2.

[0016] The steam pipe 5 passes through the inside of the air inlet pipe 3 and the inner wall of the tank 1, and extends from the bottom of the other side to the outside of the tank 1 to connect to the hopper 4. The steam pipe 5 in the above design can heat the inside of the air inlet pipe 3, the tank 1 and the hopper 4, thereby ensuring that the short-chain saturated fatty acids in the oily exhaust gas do not solidify, and ensuring complete purification of the exhaust gas.

[0017] The hopper 4 is equipped with an inlet pipe 42 and an outlet pipe 43. The steam pipe 5 enters the hopper 4 through the inlet pipe 42 and exits through the outlet pipe 43. In the above design, the steam pipe 5 passes through the hopper 4 to heat the hopper 4, prevent the discharge pipe from being blocked by solidified grease, and ensure that the waste material from the esterification reaction in the oily exhaust gas can be discharged from the bottom discharge pipe.

[0018] The tank body 1 has a feeding port 11 and a liquid inlet 12 at the top and side of the gas outlet pipe, and a drain port 13 on the outer wall of the tank body. The feeding port 11 and liquid inlet 12 in the above design can be used to feed materials for purifying oily exhaust gas and reaction liquid.

[0019] A support plate 6 is provided on the middle of the outer side of the tank body 1, which facilitates the placement of the entire tank body 1 through the outer support.

[0020] In the specific reaction process, before the oily exhaust gas is introduced, the steam pipe 5 is opened to allow steam to flow through the steam pipe 5, thereby heating the air inlet pipe 3 and the entire tank 1. Then, the reactants and reaction liquid are added through the feeding port 11 and the liquid inlet. Subsequently, the oily exhaust gas is sent into the air inlet pipe 3 and then into the tank 1 to react with the reactants. The waste is discharged from the discharge port 41 at the bottom, and the purified exhaust gas is discharged from the exhaust pipe 2.

[0021] The above description is merely an embodiment of this application and does not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
