Problems solved by technology

[0004] However, due to the narrow flow channel between the plates of the detachable plate water generating device, the flow channel is easily blocked after the plates are scaled, and the plates must be disassembled and cleaned regularly; at the same time, the plates are sealed with gaskets, Under the action of seawater, the gasket will be corroded and aged, so the gasket needs to be replaced regularly, which increases the maintenance cost of the seawater desalination device and shortens the continuous operation time; in addition, due to the limitation of its own structure, it can The temperature and pressure of the heat source of the split-plate water-making device should not be too high, and the adaptability to the parameters of the heat medium is poor

Embodiment Construction

[0042] As shown in the figure, a welded plate type water generator is provided with a bracket 1, and an evaporator and a condenser are welded on the bracket 1, and the evaporator includes an evaporator shell 2 and a Evaporator plate bundle 12 within body 2.

[0043] The evaporator shell 2 is provided with a heat medium inlet pipe box 203 , a heat medium outlet pipe box 204 , a preheated seawater inlet pipe box 205 and a concentrated seawater outlet pipe box 206 .

[0044] The evaporator plate bundle 12 includes a plurality of rectangular heat exchange plates 12a and four toothed plates 12b arranged in parallel up and down. a raised structure.

[0045] There are welding connection areas on all four sides of the heat exchange plate 12a, wherein the welding connection areas of one set of opposite sides are flush with the bottom of the groove on one side, and the welding connection areas of the other set of opposite sides are flush with the top of the groove on the same side Eac...

Abstract

A welded plate-type water generator and a manufacturing method thereof are provided with a bracket, and an evaporator and a condenser are welded on the bracket, and both the evaporator and the condenser adopt a plate-type heat exchange structure. The structure of welding connection is adopted respectively. The evaporator shell and the evaporator plate bundle and between the condenser shell and the condenser plate bundle are also completely welded, and the evaporator and the condenser are welded by a common partition plate. The whole product has a compact structure and reliable connection, which improves the pressure bearing and temperature resistance performance of the plate-type water generator, prolongs the service life, and facilitates maintenance.

Description

technical field [0001] The invention relates to a water making device for desalinating seawater, in particular to a welded plate type water making device and a manufacturing method thereof. Background technique [0002] The existing seawater desalination technology usually adopts reverse osmosis method and distillation method. Due to the phase change of seawater in the distillation method, the generated steam passes through the vapor-liquid separator and then condenses to form fresh water. The water quality of the product is high and the salt content is less than 5ppm, which can be used as boiler feed water. The cost is lower, so the distillation method is more widely used than the reverse osmosis method. [0003] At present, the water generators used in seawater desalination by distillation are divided into "tube-shell" heat exchange type water generators and detachable water generators (hereinafter referred to as detachable plate type) according to the different heat exch...
