 【Three type double detachable spiral plate
     
      Spiral plate heat exchanger is a kind of high efficient heat exchanger devices, applicable to steam vapor, vapor - liquid, liquid - liquid, the heat transfer fluid. It is suitable for chemical, oil, solvents, pharmaceutical, food, light industry, textile, metallurgy, steel rolling, such as coking industry. According to the structural form can be divided into not detachable type (Ⅰ) spiral plate and detachable type (Ⅱ, Ⅲ) spiral plate heat exchanger.
      Spiral plate heat exchanger through many years practice shows that it is a kind of high efficient heat exchange equipment, it is suitable for chemical, oil, solvent, medicine, food, light industry, textile, metallurgy, steel rolling, such as coking industry in the application. Heat exchanger from the contemporary international advanced technology, the unique optimal design and manufacture of liquid - liquid, steam - water heat exchanger. Product structure process by Sweden's al generation "company standards, spiral plate end USES ruffled argon arc welding," zenith distance column "special process for capacitors battery contactor, improve the quality of the inner and exterior recognised by" baosteel ", can replace imported. < br > & have spent & have spent & have spent & have spent Not detachable type spiral plate heat exchanger is according to standard JB/TQ724-89 - machine department not detachable type form of spiral plate heat exchanger, the provisions of the basic parameters and the size and design, it has simple manufacture, low cost, small volume and heat transfer performance is good wait for an advantage, but also has its disadvantages, such as mechanical cleaning, not bad not easy maintenance etc, choose the selection should be based on the actual situation of engineering concrete equipment make it most effective.
Structure and performance
    1, this equipment is suitable for: liquid - liquid, gas - gas, gas-liquid convection heat transfer can be used for steam condensation and liquid evaporation heat transfer, chemical industry, petroleum, medicine, machinery, electric power, light industry and textile industries are optional.
    2, this equipment is composed of two pieces of steel plate, formed two uniform spiral channel, two heat transfer by the complete counter-current flow, can be applicable to small temperature difference heat transfer, and facilitate the recovery of low temperature heat source and can accurately control the outlet temperature.
    3, takeover is tangential structure in the shell, local resistance is small, the curvature of the helical channel is uniform, the fluid flow within the device without big reversing, the total resistance is small, so that can improve the design flow rate of high heat transfer capability.
    4, spiral channel is welding seal, sealed performance is good, structure and reliable.
    5, not easy to repair, especially the internal plate to very difficult to repair, the problems of some factory car all the equipment on both ends of the weld, after repair welding plate flattening rolled again, and again do consume too much time, for selecting the spiral plate heat exchanger corrosion protection is very important.
    6, cannot undertake mechanical cleaning, production practice has proved that the spiral plate heat exchanger compared with general shell and tube heat exchanger is not easy to jam, especially the suspended particles impurities such as sand, small shells not easy in the screw channel deposition, analysis its reason; Because it is single channel impurity within the channel deposit formed a revolving flow also will improve to make it develop, two accidents because no dead Angle, spiral channels in the impurities are easy to be out.
    7, because the screw channel with spacer pillar support channel spacing, jilt to can not have fibrous material (cotton, grass, leaves, etc.) into the internal heat exchanger.
    8, strictly control the outlet temperature of cooling water at a temperature below that at which scale.
    9, the commonly used cleaning method is to use steam blowing off or alkaline cleaning, steam blowing to take over, blow the impurity from the equipment, a lot of use factory think this is effective method.
Detachable type (Ⅱ, Ⅲ) spiral plate heat exchanger
    Structure principle and not detachable heat exchanger basic same, but the channel with detachable cleaning, seal head seal on both ends. Especially for viscous and precipitation of liquid fluid and fluid exchange, and a liquid gas, steam condensation. Due to the need to add detachable heat exchanger head, flange and other components, equipment cost is slightly bigger than a non detachable heat exchanger.
The basic parameters
    Nominal pressure of the spiral plate heat exchanger PN regulation 0.6, 1, 1.6, 1.6 Mpa (namely, the original 6, 10, 16, 25 kg/cm2)(refers to the single channel with the maximum working pressure) test pressure is 1.25 times of working pressure.
    Spiral plate heat exchanger and the medium contact part of the material, carbon steel Q235A, Q235AF, acid for SUS321 steel, SUS304 stainless steel. Other materials can be opted according to user requirements.
    Allowed working temperature: t = 0 ~ + 350 ℃ of carbon steel, stainless steel, acid steel t = - 40 ~ 500 ℃, heating decompression range according to the relevant provisions of the pressure vessel. Use this equipment, through contact when process calculation, to equipment within the channel fluid turbulent state. (generally liquid velocity of 1 m/Sec gas velocity 10 m/Sec).
    Can not meet the requirement of the use of a single equipment, can use more than one combination, but when combined must meet the following requirements:
    Parallel combination, series combination: the equipment is the same as the channel spacing. Hybrid combination: a channel in parallel, series a channel.
Stainless acid-resistant steel PN0.6, 1.6 MPa not detachable type (type Ⅰ) spiral plate heat exchanger
