Description

Technical Field

[0001] The utility model belongs to the technical field of condensers, and particularly relates to a two-stage vacuum oil filter condenser. Background Art

[0002] A condenser is a commonly used device in chemical production, mainly used for liquefying materials. The condensers in the prior art are divided into shell-and-tube condensers and plate condensers. Their working principle is that after the gas enters the condenser, it contacts the tube wall or the plate body and undergoes heat exchange, so as to achieve the effect of cooling and condensing the gas.

[0003] CN105043125B discloses a condenser. In the working state, an exhaust port communicated with the inner cavity is arranged at the upper end of the shell, a liquid discharge port communicated with the inner cavity is arranged at the lower end of the shell, an air inlet communicated with the inner cavity is arranged on the shell between the exhaust port and the liquid discharge port, the vertical distance between the air inlet and the exhaust port is greater than the vertical distance between the air inlet and the liquid discharge port, a guiding structure for guiding the airflow entering from the air inlet is arranged in the inner cavity of the shell, and a heat exchange structure for reducing the temperature of the shell by using a cold medium is fixed outside the shell; the above structure has the following advantages: the heat exchange time between the gas and the inner cavity side wall is lengthened, and the cooling effect of the condenser is improved; heat exchange will also occur between the liquefied gas and the unliquefied gas, further improving the cooling effect of the condenser, and the liquefied gas will not crystallize on the side wall of the inner cavity.

[0004] There are still some problems in the use of the above patent, such as:

[0005] 1. When the outside air enters, there is a lack of filtration of the air, resulting in the entry of dust or other impurity particles in the air, which thus adhere to the inner wall of the shell or the surface of other components, reducing the heat exchange efficiency of the shell temperature;

[0006] 2. When used for a long time, the dust impurities in the outside air are easily attached to the surface of the air inlet hole, thus causing blockage of the air inlet hole, reducing the air intake volume inside the shell, and thus reducing the heat exchange efficiency of the shell temperature. Therefore, we need to propose a two-stage vacuum oil filter condenser. Content of the Utility Model

The bottom of the fixed box 3 is provided with a cleaning mechanism 7 for removing dust from the air inlet hole 4 to prevent the air inlet hole 4 from being blocked by dust. Through the filtering mechanism 6 and the cleaning mechanism 7, during use, the filtering mechanism 6 can filter the incoming air, removing dust and other impurity particles in the air, preventing dust or other impurity particles in the air from adhering to the inner wall of the housing 1, thereby improving the efficiency of temperature heat exchange inside the housing 1.
