The 15th Shanghai International Chemical Equipment Fair (“CTEF”) was held on August 23-25, 2023 at the Shanghai New International Expo Center, and King Dupont presented a number of heat transfer equipment at this industry-level exhibition, displaying a variety of core technology products for the fields of HVAC, evaporation and condensation, as well as system integration. King Dupont will exhibit its core technology products for HVAC, evaporative condensing and system integration. Welcome to visit our booth: booth w2668, Hall W2, Shanghai New International Expo Center.

I. Plate heat exchanger

Plate heat exchanger is a series of metal plates with a certain corrugated shape stacked into a high-efficiency heat exchanger. Between the various plates to form a thin rectangular channel, heat exchange through the plate. Plate heat exchanger is the ideal equipment for liquid-liquid and liquid-vapor heat exchange. It is characterized by high heat exchange efficiency, small heat loss, compact and lightweight structure, small footprint, wide range of applications, and long service life. Under the same pressure loss, its heat transfer coefficient is 3-5 times higher than that of tubular heat exchanger, occupies an area of one-third of that of tubular heat exchanger, and the heat recovery rate can be as high as 90% or more.

Half-welded plate heat exchanger

The corrosive medium flows into the welded channel and comes into contact with two circular orifice gaskets between a pair of welded plate sheets. The non-corrosive medium flows into the conventional gasket channel. Especially suitable for ammonia and Freon and other refrigerants evaporation and condensation, for the chemical industry and general process heat exchange gasket corrosive medium is also an ideal heat exchange equipment, in the relevant field can also be called plate evaporator or condenser, etc..

All-welded plate heat exchanger

The conventional thickness of all-welded plate in 1.0mm, 1.2mm, commonly used in high temperature, high pressure conditions, to deal with some of the harsh working conditions of the heat exchange occasions.

Brazed plate heat exchanger

Brazed plate is thinner, the thickness is generally in 0.4mm and cancel the rubber strip, eliminating the corrosion problem, can withstand higher temperatures and pressures. Compared with fully welded plate heat exchanger, brazed plate heat exchanger is more suitable for: small footprint, space constraints, high temperature and high pressure, flow rate is not large conditions, the maximum flow rate is only 150m³/h.

Wide flow channel plate heat exchanger

Wide flow channel plate heat exchanger using a unique coarse corrugated, wide gap channel structure design, the medium can flow through the plate heat transfer surface without restriction without clogging, retention phenomenon, and effectively prevent solid particles, suspended solids, fibers and viscous material deposition, clogging.

2、Evaporator

Jindobang evaporator, more than 10 years of evaporation crystallization equipment research and development manufacturer, complete qualification, professional team, and many universities and colleges cooperation research, with a number of invention patents, focusing on the production of evaporation crystallization equipment manufacturing, to provide one-stop solution for hazardous wastewater treatment, the strength of the certified, is the leading industrial wastewater zero-discharge solution provider.

Low temperature heat pump evaporator

Low-temperature heat pump evaporator is the use of vacuum state of the material boiling point of the physical characteristics of the reduction, through the vacuum pump will evaporate the room atmospheric pressure down to -95Kpa - 97Kpa, the atmospheric pressure conditions of the boiling point of water in the 35-45 ° C, and at the same time the use of heat pumps inverse Carnot cycle principle, through the compressor to act on the refrigerant to achieve energy recycling in order to achieve the purpose of energy saving and consumption reduction. At the same time using the heat pump inverse Carnot cycle principle, through the compressor acts on the refrigerant to realize the energy recycling, so as to achieve the purpose of energy saving and consumption reduction. It can save more than 90% of the treatment cost for customers.

MVR Evaporator

Through the working principle of MVR (Mechanical Vapor Recompression Technology), the 85℃ steam generated from the wastewater that has been heated to 85℃ is compressed again to increase the temperature rise, and the 85℃ steam is compressed to 121℃ steam, and the high-temperature steam is used to heat and evaporate the wastewater again and condense the condensate during the process of exothermic heat release.The advantage of the MVR evaporator lies in the secondary use of the steam, with low energy consumption, and a ton of processed wastewater can be 40-50Kwh. Wastewater can 40-50Kwh/Ton.

Multi-effect evaporator

Through the waste heat or steam and other energy, to provide waste water evaporation treatment. Ton of wastewater treatment steam consumption 1.2m³/Ton (according to multi-effect and different). There are no major limitations on the amount of water and type of wastewater that can be applied. Three-effect evaporation is suitable for making products directly from concentrated dilute solutions, or reprocessing concentrated solutions to produce solid products; while concentrating solutions and recovering solvents; in order to get pure solvents.

3. Heat exchanger unit

Plate heat exchanger unit, by the plate heat exchanger, intelligent temperature control device, intelligent electronic control device, circulating pumps, make-up water pumps, pressure stabilized expansion tank, make-up (condensation) tank, filters, valves, meters, sensors, piping base and other components of the heat exchange equipment, widely used in factories and villas, institutions and schools, residential communities and other civil buildings or shopping malls and hotels, hotels, resorts, and other commercial buildings, heating, air-conditioning, water for bathing, and all kinds of places that need heat exchange.

King Dupont heat exchanger unit, intelligent automation, easy to operate, can be realized unattended, centralized digital display; protection functions: pressure loss overpressure protection, over-temperature protection; unit optimization design, reasonable layout, compact structure, small footprint, saving investment in civil engineering, easy to install and maintain, high efficiency and fast heat, heat energy saving, easy to increase capacity, simple maintenance.

The chemical equipment exhibition, gathering the head enterprises in various fields, displaying the latest advanced technology and equipment at home and abroad, can meet the one-stop purchasing needs of chemical production enterprises. king Dupont exhibition site for you to prepare related product catalogs and peripheral, looking forward to the majority of corporate customers to visit the exchange!
