Embodiment Construction

[0041] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0042] A multi-stage separatory plate condenser, such as Figure 2-11 As shown, it includes a front end cover plate 2, a rear end cover plate 1, at least one heat exchange plate 7, at least one water side gasket 8 and at least one steam side gasket 6, the water side gasket 8 and the steam side seal Pads 6 are respectively located on both sides of the heat exchange plate 7 to form a steam flow channel and a cooling water flow channel. The heat exchange plate 4 is provided with a steam inlet corner hole 65, a liquid separation corner hole for the first to nth (n is a natural number greater than 1) stage condensate, a cooling water inlet corner hole, a cooling water outlet corner hole and The liquid separation angle hole 64 of the final stage condensate, wherein the liquid separation angle hole is used to drain the condensate out of the condens...

Abstract

The invention discloses a multistage liquid-separation plate-type condenser. The multistage liquid-separation plate-type condenser comprises a front end cover plate, a rear end cover plate, a heat transferring plate, a water-side sealing gasket and an steam-side sealing gasket, wherein the water-side sealing gasket and the steam-side sealing gasket are located at the tow sides of the heat transferring plate respectively and form a steam flow channel and a cooling water flow channel with the adjacent heat transferring plate, the front end cover plate, or the rear end cover plate, several liquid-separation sealing strips are arranged in the steam-side sealing gasket, the water-side sealing gasket forms a condensate groove with the adjacent heat transferring plate or the front end cover plate, and the lower side of the condensate groove is communicated with a liquid-separation corner hole. The multistage liquid-separation plate-type condenser has the advantages that lowering of condensation heat transferring thermal resistance can be favored; condensation heat transferring of the steam is maintained under high dryness, a high coefficient of heat transfer is maintained, and thus the purpose of intensification of condensation heat transfer can be achieved; the multistage liquid-separation plate-type condenser is guaranteed to work in an optimum liquid-separation working condition, and thus the effect of liquid-separation condensation of the hear transfer can be guaranteed; meanwhile, the structure is simple, processing cost is lowered, and the advantages that a compact structure of a traditional plate-type heat transfer is maintained, and the economical efficiency is good are maintained.

Description

[0001] 【Technical field】 [0002] The invention relates to the field of condensers, in particular to a multi-stage liquid-separating plate condenser. [0003] 【Background technique】 [0004] The plate heat exchanger is composed of a series of corrugated plates, and the sealing gasket is used to form narrow groove flow channels between the plates. The hot and cold fluids enter the adjacent flow channels through the corner holes on the heat exchange plate. Heat exchange is carried out through metal heat exchange plates. Plate heat exchanger is a high-efficiency heat exchanger with good heat transfer performance and compact structure. It is widely used in heat exchange between liquid and liquid medium. [0005] In many cases, the single-phase liquid-liquid The heat transfer plate heat exchanger is directly used as a condenser. There are usually two disadvantages: one is that the steam corner hole is usually designed according to the flow of liquid, and the specific volume of...
