Positive displacement heat exchanger

Overview

SVRJ series positive displacement heat exchanger is based on floating coil heat exchanger with increased volume. It has automatic temperature control, it fully utilizes steam energy, and it is a new type of energy-efficient water heater. Ordinary heat exchangers generally need to be equipped with water-to-water heat exchangers to reduce the temperature of steam condensate for reuse. The condensate effluent temperature of the energy-saving volumetric heat exchanger is about 75 ° C, which can be directly returned to the boiler room for repeated use. This reduces equipment investment, saves the area of the heat exchanger room, and thus reduces the capital construction cost. Therefore, energy-saving volume heat exchangers are welcomed by customers.

SVRJ series volumetric heat exchange units use high-quality copper as floating coils, which have strong metal heating and creep performance. When cold water enters the shell, it is forced to pass through the floating coils through a special flow guide device. The laminar flow is destroyed, enhancing the heat transfer effect. The heat medium is steam, the working pressure of the heating pipe is less than 0.6 MPa, the working pressure of the shell is 0 to 1.6 MPa, and the outlet hot water temperature is 65 ° C. Energy-saving volumetric heat exchangers, there are three kinds of shell materials: carbon steel Q235-A, B, stainless steel Igr18Ni9Ti, carbon steel lined with copper, U-shaped tube materials are copper tube T2, stainless steel tube ICr18Ni9Ti, according to need Choose it. When steam or high-temperature hot water passes through the control valve and the main heat medium, it enters each of the parallel floating coils for heat exchange. When the heat medium flows to the coil outlet, it becomes condensed water or low temperature water, and finally flows out of the heat exchange unit. An expansion water tank is provided, which is connected to a water heater to discharge the expansion water volume.

SVRJ type heat exchanger

Features

SVRJ series volumetric heat exchange unit is a new type of high-efficiency energy-saving heat exchange equipment, which is better than similar products on the current market. Compared with similar products at home and abroad, it has the following characteristics:

If the water contains hardness and salt, when the heat exchanger is used, scales will be formed on the wall of the vessel and the tube wall, which will reduce the heat exchange rate and increase energy consumption, which will affect the use. Therefore, certain softening measures should be adopted.

Selection

SVRJ series positive displacement heat exchanger can be carefully designed according to the user's heat medium and heating medium. Therefore, customers must provide: the nature of the heat medium, heating medium, flow rate, and inlet and outlet temperature when ordering, such as the heat exchanger Material, form and other special requirements must be stated in writing.
