Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
As shown in fig. 1 and 2, the inverted T-shaped full-liquid evaporation separation superheater comprises a lower evaporation area 1, an evaporation area shell-side outlet gas-liquid separation area 2, an upper steam superheating area 3, a connecting section 4 and a support 5. The steam superheating area 3 is vertically arranged at the upper part of the horizontally arranged evaporation area 1; the shell pass of the lower evaporation zone 1 is connected with the tube pass of the upper steam superheating zone 3 through a gas-liquid separation zone 2; the shell pass of the upper steam superheating area 3 is connected with the tube pass inlet of the lower evaporation area 1 through a connecting section 4.
The lower evaporation zone 1 can be of a tubular full-liquid evaporator structure or a plate full-liquid evaporator structure, and the embodiment is a tubular technical scheme. The gas-liquid separation zone 2 and the steam overheating zone 3 are uniformly distributed at the shell pass steam outlet of the evaporation zone 1 and are integrated with the shell pass steam outlet of the evaporation zone 1. In order to meet the separation overheating effect of the full-liquid evaporator, reduce the on-way resistance as much as possible and save the installation space, the steam overheating area and the gas-liquid separation area are uniformly distributed at the shell-side steam outlet of the evaporation area and are integrated with the shell-side steam outlet of the evaporation area. The vapor from the inclusion liquid drops in the evaporation area finishes vapor-liquid separation in the vapor-liquid separation area, and the separated vapor enters the vapor superheating area to be superheated, so that a vapor product meeting the quality requirement is obtained.
The gas-liquid separation zone 2 at the shell pass outlet and the upper steam superheating zone 3 can be connected through a flange (as shown in figure 1) or a welding connection (as shown in figure 3). The flange connection mode can realize that overheated district 3 dismantles with evaporation zone 1, gas-liquid separation district 2, conveniently examines the maintenance to overheated district 3, gas-liquid separation district 2, evaporation district 1 part, and welded connection structure can not dismantle the separation district part.
The steam superheating area 3 is of a single-tube-pass shell-and-tube superheater structure and is used for reducing on-pass resistance as much as possible.
The utility model discloses a working process: cold flow enters the inverted T-shaped full-liquid evaporation separation superheater from the cold flow inlet B1, is subjected to heat exchange with heat flow in the evaporation area 1 to be vaporized into steam, the steam containing a small amount of liquid is subjected to steam purification through the gas-liquid separation area 2, the purified steam is subjected to heat exchange with the heat flow in the superheating area 3 to form a steam product meeting the quality requirement, and the steam product enters the steam turbine through the cold flow outlet B2. The heat flow enters from a heat flow inlet A1 of the superheat area, enters into the evaporation area through the connecting section after exchanging heat with purified steam in the superheat area, and flows out of the inverted T-shaped full liquid evaporation separation superheater through a heat flow outlet A2 after exchanging heat with cold flow in the evaporation area.
