Description

An air-cooled graphite condenser

technical field

The utility model belongs to the mechanical field and relates to a heat exchange device, in particular to an air-cooled graphite condenser.

Background technique

Air-cooled condensers have excellent performances such as environmental protection, water saving, and energy saving, and are being gradually popularized and applied in various industries. However, affected by factors such as corrosion, most air-cooled condensers are made of metal materials. Graphite materials not only have excellent thermal conductivity, but also have good corrosion resistance. Using graphite materials to make air-cooled condensers has high application value.

Utility model content

The utility model discloses an air-cooled graphite condenser which completely solves the fouling problem and saves water, electricity and cost.

The purpose of this utility model is achieved in the following ways:

An air-cooled graphite condenser, including a hot steam inlet, a condensed liquid outlet, a tube side and a shell side, the tube side is composed of a plurality of graphite tubes, and the shell side is made of thin metal tightly wound on the outside of the graphite tube It consists of sheets, and multiple graphite tubes are arranged in parallel. The metal sheet is preferably an aluminum sheet or a copper sheet.

The hot air outlet is connected to the induced draft fan, and the opposite side of the hot air outlet is provided with a cold air inlet.

When in use: hot steam enters the graphite condenser through the hot steam inlet, condenses into a liquid through the graphite condenser, and is discharged by self-flow through the condensed liquid outlet. The exchange becomes hot air and is discharged upward from the hot air outlet.

The utility model uses the metal winding sheet wound outside the graphite tube to increase the heat exchange area, and the graphite and the aluminum (or copper) winding sheet are closely bonded to enhance the heat exchange effect (the heat exchange effect between solids is the best, if the If the joint is not tight, it will affect the heat transfer effect).

The traditional graphite heat exchanger uses water as the refrigerant. Ordinary water contains a certain amount of heavy metals such as calcium and magnesium. Long-term operation of hot steam above 100°C will easily lead to fouling of the condenser, which will seriously affect the cooling effect. The method of adding chemicals to the water reduces scaling, but the use of chemicals will form a certain cost of chemicals, and the circulating water must be replaced regularly and quantitatively. Using the graphite air-cooled condenser of the utility model can completely solve the scaling problem, save water, save electricity, and save costs.
