Abstract

A condenser for drying equipment, and drying equipment. The front side wall of a hollow chamber of the condenser includes a first arc structure, a second arc structure, and a flow dividing structure; the flow dividing structure is opposite to an air inlet; the left and right side walls of the hollow chamber are arc-shaped; the flow dividing structure can divide the gas entering from the air inlet into a first airflow and a second airflow, and enable the first airflow and the second airflow to enter the first arc structure and the second arc structure along a tangential direction of the first arc structure and second arc structure, to provide centrifugal and rotational airflow. Since the first airflow and the second airflow rise centrifugally and rotationally, the strokes of the first airflow and the second airflow in a condenser body are lengthened, thus improving the cooling effect.

First claim

What is claimed is:

1 . A condenser for a drying apparatus, the condenser comprising:
a body and a cooling water pipe, and a water outflow end of the cooling water pipe in communication with a hollow chamber formed inside the body, and a front side wall of the hollow chamber is provided with a first arc-shaped structure, a second arc-shaped structure and a flow splitting structure located between the first arc-shaped structure and the second arc-shaped structure; a gas inlet is provided on a rear side wall of the hollow chamber, and the flow splitting structure is opposite to the gas inlet; both a left side wall and a right side wall of the hollow chamber are configured to be arc-shaped, two ends of the left side wall are smoothly connected with the first arc-shaped structure and the rear side wall respectively, and two ends of the right side wall are smoothly connected with the second arc-shaped structure and the rear side wall respectively; the flow splitting structure is arranged to be capable of splitting a gas entering from the gas inlet into a first gas flow and a second gas flow, and is arranged to enable the first gas flow and the second gas flow to enter the first arc-shaped structure and the second arc-shaped structure substantially in a tangential direction of the first arc-shaped structure and a tangential direction of the second arc-shaped structure respectively, thereby enabling the first gas flow to rise centrifugally and rotationally along the first arc-shaped structure, the left side wall and a left part of the rear side wall, and enabling the second gas flow to rise centrifugally and rotationally along the second arc-shaped structure, the right side wall and a right part of the rear side wall.

2 . The condenser according to claim 1 , wherein the flow splitting structure is arranged in a left-and-right symmetrical manner, and a central line of the flow splitting structure coincides with a central line of the gas inlet, so that the first gas flow and the second gas flow have substantially the same flow rate.

3 . The condenser according to claim 1 , wherein the rear side wall is provided with a first arc-shaped guide structure and a second arc-shaped guide structure, so that the first gas flow and the second gas flow can smoothly flow toward the first arc-shaped structure and the second arc-shaped structure respectively.

4 . The condenser according to claim 1 , wherein the front side wall is provided with a water guide groove, a top end of the water guide groove is connected with the water outflow end of the cooling water pipe, and a bottom end of the water guide groove is connected with the flow splitting structure.

5 . The condenser according to claim 4 , wherein the water guide groove is inclinedly arranged in a direction approaching the rear side wall from top to bottom.

6 . The condenser according to claim 4 , wherein the flow splitting structure is inclinedly arranged in a direction away from the rear side wall from top to bottom.

7 . The condenser according to claim 4 , wherein the flow splitting structure comprises a first arc-shaped flow splitting part and a second arc-shaped flow splitting part; one end of the first arc-shaped flow splitting part is smoothly connected with the first arc-shaped structure, the other end of the first arc-shaped flow splitting part is smoothly connected with one end of the second arc-shaped flow splitting part, and the other end of the second arc-shaped flow splitting part is smoothly connected with the second arc-shaped structure.

8 . The condenser according to claim 1 , wherein the left part of the rear side wall is provided with a first water intercepting groove, so that water droplets in the first gas flow are separated from the first gas flow.

9 . The condenser according to claim 1 , wherein the right part of the rear side wall is provided with a second water intercepting groove, so that water droplets in the second gas flow are separated from the first gas flow.

10 . A drying apparatus, comprising the condenser according to claim 1 .
