Abstract
The invention relates to a vapor heat exchanger provided with a venturi, which comprises a heat exchange container and a vapor pipeline, wherein the heat exchange container comprises a heat exchanger body and a heat exchange coil tube; the heat exchanger body is a sealed container in which water bathing is carried out; the heat exchanger body is provided with a vapor inlet tube and a water overflow tube; the heat exchange coil tube is arranged in the heat exchanger body; the vapor pipeline is provided with a vapor electromagnetic valve and arranged in the heat exchanger body through the vapor inlet tube; the end parts of the vapor pipeline which is arranged in the heat exchanger body are fixed with vapor nozzles; the venturi is fixed in the heat exchanger body; and the vapor nozzles are arranged in the contraction cavity mouth of the venturi. The vapor heat exchanger provided by the invention has the advantages that the vapor quantity for heat exchange can be stably controlled; the heat exchange temperature is easily controlled; the venturi can reduce the noise because most noise is absorbed when the gas and the water are mixed; the heat exchanger has the advantages of simple structure, simplicity in operation, convenience in maintenance and strong applicability, is safe and reliable and can be applied to the heat exchange device of a vaporizer for liquefied gas, liquid natural gas, ammonia and the like.
Description
(1) technical field
The present invention relates to steam water-bath type heat exchanger, particularly a kind of vapor heat exchanger that is provided with Venturi tube.
(2) background technology
In steam water-bath type heat exchanger, when steam carried out the thermal source exchange, way in the past used steam directly to blow water or utilize plate type heat exchanger to carry out indirect heat exchange.This dual mode on using, respectively have need not, preceding a kind of method is fairly simple, but to require be withstand voltage container, otherwise the steam of high pressure will rise the container that is filled with water and split and deform under the steam pressure effect, can produce the very violent sound simultaneously.The temperature control of heat exchange is coarse.The latter carries out heat exchange with plate type heat exchanger and just can effectively address the above problem, and can effectively reduce noise and vibrations, can also control temperature accurately, but complex manufacturing technology.
(3) summary of the invention
The objective of the invention is at above-mentioned existing problems, a kind of simple in structure, safe and reliable, bath temperature is controlled easily, operating noise is low and applicability is strong venturi type vapor heat exchanger is provided.
Technical scheme of the present invention:
A kind of vapor heat exchanger that is provided with Venturi tube, comprise heat exchange container and steam pipework, heat exchange container comprises heat exchange body and heat exchange coil, the heat exchange body is the airtight container that carries out water-bath, the heat exchange body is provided with steam inlet pipe and water overflow pipe, and heat exchange coil places in the heat exchange body and in external heat transferring medium inlet tube and the heat transferring medium outlet of being provided with of heat exchanger; Steam pipework is provided with steam electromagnetic valve and the steam inlet pipe by the heat exchange body enters in the heat exchange body, the end that is positioned at the steam pipework of heat exchange body is fixed with steam jet, Venturi tube is fixed in the heat exchange body, and steam jet is positioned at the contraction accent of Venturi tube.
Described steam jet is a conical structure, and bore is that 6mm, length are 80mm, is threaded with the steam pipe screw thread, adopts the stainless steel manufacturing.
Described Venturi tube inlet diameter is 40mm, and the collapsible tube central angle is 15 degree, and the anemostat angle is 20 degree, and entire length is 500mm, adopts the aluminium manufacturing.
Working procedure of the present invention:
Steam enters into heat exchange body inside from inlet tube, 0.2MPa the steam of pressure carries out high velocity jet by nozzle, enter into Venturi tube, according to the rapid before this contraction of venturi principle, expansion rapidly again, make the import of Venturi tube produce great negative pressure, make the water in the heat exchanger under the effect of negative pressure, enter into Venturi tube and vapor mixing, finish heat exchange.
Advantage of the present invention is: be used for the control that the quantity of steam of heat exchange can be more stable, and the heat exchange temperature is easy to control; Adopt Venturi tube that noise is reduced, because most of noise is absorbed when mixing at vapour, water; This heat exchanger structure is simple, operation easily, safe and reliable, easy to maintenance, applicability is strong, can be applicable to the heat-exchanger rig of gasifiers such as liquefied gas, liquified natural gas and ammonia.
