Efficient air cooler

Abstract

The invention discloses an efficient air cooler. The efficient air cooler comprises heat exchange tubes, manifolds, end covers, an explosion-proof fan, a fan cover, supporting columns and tube plates.The two tube plates are arranged in parallel, the two supporting columns are fixedly connected to the lower portions of the tube plates, the heat exchange tubes are arranged between the adjacent faces of the tube plates, the heat exchange tubes are obliquely arranged, and the multiple manifolds are arranged on the opposite faces in a staggered manner; the manifolds on the two sides communicate ina Z shape through the heat exchange tubes, the end covers are arranged on the end faces of the manifolds, a liquid inlet is formed in one end of the uppermost manifold, and a liquid outlet and an airexhaust and a sewage drainage outlet are formed in one end of the lowermost manifold; and the number of the supporting columns is four, connecting rods are arranged at the positions, close to the topends, of the adjacent supporting columns, the four connecting rods are distributed in a rectangular shape, one end of the fan cover is connected with the connecting rods through flanges, the other end of the fan cover is fixedly connected with the explosion-proof fan, extending edges are arranged on the two side faces in the length direction of the fan cover and fixed to the two side edges of thetube plates, liquid in the heat exchange tubes is forcedly cooled through the explosion-proof fan, and sand in the liquid can be gradually precipitated in the flowing process and is concentrated in the manifolds.

Description

technical field [0001] The invention relates to the technical field of desanding and cooling of produced water, in particular to a high-efficiency air cooler. Background technique [0002] The produced water of some oil and gas fields contains a lot of sand and other impurities, and the temperature is very high. During the treatment process, sand can easily block equipment and valves, and erode pipelines. High temperature also places higher requirements on subsequent equipment. This undoubtedly increases the procurement cost and maintenance cost of the oil production station. Therefore, it is necessary to carry out sand control and cooling treatment on the produced water at the wellhead. [0003] At present, the desanding of produced water mostly adopts the method of combining sand removal tank and heat exchanger, that is, the sand removal tank is used to remove sand and then enters the heat exchanger for cooling treatment. Due to the complex internal structure of the san...

AI Technical Summary

Problems solved by technology

Due to the complex internal structure of the sand removal tank, it is easy to block and inconvenient to clean

If the sand removal is not thorough, it is also prone to clogging after entering the heat exchanger, which is difficult to clean and reduces the heat exchange efficiency

This method has high procurement costs, large floor space, and high operation and maintenance costs.
