Embodiment 1

[0024] A multi-layer snake coil flash heater, such as figure 1 with figure 2 As shown, it includes a head 1, a cylinder body 2, a coil assembly 3 and a support plate 4. The head 1 and the cylinder body 2 are detachably connected through a head flange 11 and a cylinder body flange 21. The disk The pipe assembly 3 is located in the head 1 and the cylinder body 2, and is fixedly connected with the head 1. The coil assembly 3 is arranged in 5 layers from bottom to top, and the coils in each layer are arranged reciprocatingly in an S shape. The total length of the coil is about 40000mm, the coil pipe diameter gradually increases from bottom to top, as follows: φ45mm, φ57mm, φ76mm and φ89mm. The coil lengths of the four different pipe diameters are all about 10000mm. Different pipe diameters are connected by different diameter pipes. The bottoms of each layer of coils are on the same plane, and the plane has an included angle of 3 degrees with the horizontal plane, and the plane...

Abstract

A multi-layer coiled tube type flash heater comprises an end socket, a cylinder, a coiled tube assembly and a supporting plate. The end socket is detachably connected with the cylinder through a flange. The coiled tube assembly is located in the end socket and the cylinder and fixedly connected with the end socket. The coiled tube assembly is arrayed from bottom to top in a multi-layer mode. Coiled tubes in each layer are arrayed in an S shape in a reciprocation mode, and the pipe diameters of the coiled tubes gradually increase from bottom to top. The multi-layer coiled tube type flash heater is simple in structure, the pipe diameters of the coiled tube assembly gradually increase from bottom to top, and vaporization space is provided for materials; the S-shaped coiled tube type is adopted, and therefore the volume and the area are large, and the heat transfer efficiency is high; a slide way is arranged in the cylinder, and therefore the coiled tube assembly can be conveniently pushed in and pulled out, and convenience is provided for overhauling; the whole coiled tube assembly inclines by a certain degree, and therefore it can be ensured that liquid inside the coiled tubes can be completely discharged, and the multi-layer coiled tube type flash heater is easy to clean and convenient to maintain.

Description

technical field [0001] The invention relates to a multi-layer snake-coil type flash heater, which belongs to the field of heat exchangers. Background technique [0002] The flash vaporization of materials consumes a lot of heat. The usual flash device is a separate heater and flash evaporator, or a spiral coil type; the split flash evaporator has a large volume area, but the material is in the heater. The flow rate is low, and it is easy to cause local blockage for some special materials, thus affecting the quality of the materials. Spiral coil flash evaporator, the material is heated and flash vaporized at the same time, the material gradually becomes a gas-liquid two-phase, the material flow rate is fast, and its volume area is low, which often makes the equipment too large, low energy utilization rate, and not easy Cleaning increases the difficulty of maintenance. Contents of the invention [0003] In order to solve the defects in the prior art that most of the flash ...
