The steam-water heat exchanger is composed of a sealing head, a heat exchanger body and a condensed liquid collector, wherein the sealing head is arranged on the upper end of the heat exchanger body and is provided with a steam inlet and a steam outlet; the condensed liquid collector is arranged on the lower end of the heat exchanger body and is provided with a condensed liquid guide pipe; the heat exchanger body is a cylinder body, and is composed of more than one independent unit; two sets of heat exchange pipes with unequal quantity are arranged in each independent unit; steam flows in different directions in each set of heat exchange pipes, one set of heat exchange pipes downwards flow, and the other set of heat exchange pipes upwards flow. All independent units are connected through pipe plates to form an integral heat exchanger body; heat exchange pipes between two independent units are staggered; the quantity of each set of heat exchange pipes in each independent unit gradually decreases along the flow direction; the outer wall of the first independent unit is provided with a cooling water inlet, and the outer wall of the last independent unit is provided with a cooling water outlet; a connecting opening of a cooling water connecting pipe is formed between two adjacent independent units. The steam-water heat exchanger can fully use heat exchange areas, the heat exchange coefficient can be increased by 30 to 50%, and material consumption can be reduced.
Description
Technical field
The present invention relates to Thermal Equipment, be specifically related to a class steam-water-to-water heat exchanger.
Background technology
At present, all kinds of heat exchangers are applied to gas or liquid medium usually.When cold and hot side heat exchange area near the time, the hot and cold stream side has the suitable coefficient of heat transfer, the operational effect of heat exchanger is better.If a side coefficient of heat transfer is lower, generally should adopt the reinforcement means, reduce this side thermal resistance.But, its characteristics are arranged then for steam-water-to-water heat exchanger.At first be that vapour condensation heat transfer intensity is higher, but variation of volumetric flow is very big; The cold water side flow is very big, and flow resistance clearly; Secondly the accumulation submergence part heat exchange surface of condensation water influences heat exchange; Strengthening surface increases the cold water side resistance, causes the downstream part heat exchange area not to be fully utilized owing to steam condenses simultaneously.Thereby traditional heat exchangers exists volume big when being used for steam and water heat exchange, and condensation water is derived problems such as not smooth.
Summary of the invention
The purpose of this invention is to provide and a kind ofly can effectively utilize heat exchange area, improve heat transfer coefficient, reduce heat exchanger volume, derive the high-efficiency steam-water-to-water heat exchanger of condensation water rapidly.
Constant flow velocity steam-water heat exchanger of the present invention is made up of end socket, heat exchanger body, condensation water gatherer three parts, and end socket is placed in the heat exchanger body upper end, and steam inlet and outlet are arranged; The condensation water gatherer is placed in the heat exchanger body lower end, and the condensation water delivery line is housed; Heat exchanger body is a cylindrical shell, is made up of more than one separate unit from top to bottom, settles two groups of heat exchanger tubes that number of tubes does not wait in each separate unit, and to press different directions mobile for steam in every group of heat exchanger tube, and one group to dirty, and one group to the upper reaches.Each separate unit is connected by tube sheet, makes it to form the heat exchanger body of an integral body.Heat exchanger tube between two separate units is staggeredly arranged; The number of tubes streamwise of every group of heat exchanger tube successively decreases.On first separate unit outer wall cooling water inlet is arranged, on last separate unit outer wall coolant outlet is arranged.Between adjacent two 1 separate units cooling water tube connector interface is arranged.
Constant flow velocity steam-water heat exchanger of the present invention makes full use of heat exchange area owing to adopt the separate multiple layer structure, has improved the coefficient of heat transfer, can reduce heat exchange area 30-50%, reduces material consumption.
Description of drawings
Fig. 1 is a constant flow velocity steam-water heat exchanger structural representation of the present invention.
The specific embodiment
Accompanying drawings embodiment is as follows:
Constant flow velocity steam-water heat exchanger of the present invention (Fig. 1) is made up of end socket 2, heat exchanger body 1, condensation water gatherer 3; Steam inlet 7 and steam (vapor) outlet 8 are arranged in the end socket portion; There are the steam that a dividing plate 6 enters with separation and the steam of discharge in end socket 2 inside, and end socket 2 and heat exchanger body 1 are connected by flange; Heat exchanger body 1 is formed by connecting by flange by two separate units; The steam flow direction of 4, two groups of pipes of set of heat exchange tubes that two groups of number of tubes of arrangement do not wait in each separate unit is opposite, and one group from top to bottom flows, and another group from bottom to top flows; Connect with tube sheet 11 between two separate units, have between the tube sheet cavity 13 with and current downflow, another group from bottom to top flows; Connect with tube sheet 11 between two separate units, cavity 13 is arranged to stockpile condensation water and steam between the tube sheet, condensation water in the cavity 13 is introduced condensation water gatherer 3 by catheter 5, and condensation water gatherer 3 is connected by sending out orchid with heat exchanger body 1, and has condensation water delivery line 12 to discharge condensation waters; Pipe in separate unit and the pipe in another separate unit are staggeredly arranged, and there is cooling water inlet 9 upper end of heat exchanger body 1, and the lower end has has cooling water communicating pipe 14 to link to each other between 10, two separate units of coolant outlet.
During the work of this uniform flow vapor-water heat exchanger, steam is entered by import 7, flows downward by set of heat exchange tubes 4, enters the set of heat exchange tubes of second separate unit, enters condensation water gatherer 3 again, enters another group set of heat exchange tubes again and upwards flows, and discharges to steam (vapor) outlet.In the separate unit in every group of set of heat exchange tubes number of tubes reduce by group along the steam flow direction, to reach the steam uniform flow, improve the purpose of heat exchange efficiency.
