Graphite modified polypropylene heat exchanger

PSGH seriesGraphite modified polypropylene heat exchangerA fully plastic structure corrosion-resistant heat exchange equipment made by secondary processing of integral reinforced polypropylene pipes, modified polypropylene laminates or pure polypropylene plates, and graphite modified polypropylene heat exchange tubes. Widely used in processes such as condensation, cooling, and heating in industries such as chemical, pharmaceutical, metallurgical, and food. This product has excellent corrosion resistance and good physical and mechanical properties.

Graphite modified polypropylene heat exchangerGraphite modified polypropylene tubular heat exchanger is a widely used heat exchanger in chemical and alcohol production. It is mainly composed of shell, tube plate, heat exchange tube, head, baffle, etc.

The required materials can be made of ordinary carbon steel, copper, or stainless steel. During heat exchange, a fluid enters from the connecting pipe of the head, flows through the pipe, and exits from the outlet pipe at the other end of the head, which is called the pipe side; Another type of fluid enters through the connecting pipe of the shell and flows out from another connecting pipe on the shell, which is called a shell side tube heat exchanger.

Graphite heat exchangers can be divided into three types based on their structure: block hole type, tube shell type, and plate type. Block hole type: assembled from several block graphite components with holes. Shell and tube heat exchanger: Shell and tube heat exchangers play an important role in graphite heat exchangers, and are divided into fixed and floating head types according to their structure. Plate type: Plate heat exchangers are made by bonding graphite plates together. In addition, there are immersion, spray, and sleeve heat exchangers (see snake tube heat exchanger, sleeve heat exchanger). Graphite heat exchangers have good corrosion resistance, are not prone to scaling on the heat transfer surface, and have good heat transfer performance. However, graphite is prone to brittle cracking and has low bending and tensile strength, so it can only be used for low pressure, even if it has the ability to withstand pressuregoodThe block hole structure generally has a working pressure of only 0.3-0.5 megapascals. Graphite heat exchangers are expensive, bulky, and rarely used. It is mainly used for heat exchange in corrosive media such as hydrochloric acid, sulfuric acid, acetic acid, and phosphoric acid, such as used as a condenser for acetic acid and acetic anhydride.

Plate heat exchanger is a new type of high-efficiency heat exchanger composed of a series of metal sheets with certain corrugated shapes stacked together. Thin rectangular channels are formed between various plates for heat exchange through half plates. Plate heat exchangers are ideal equipment for heat exchange between liquid and liquid, as well as between liquid and vapor. It has the characteristics of high heat transfer efficiency, low heat loss, compact and lightweight structure, small footprint, easy installation and cleaning, wide application, and long service life.
