Abstract
The invention belongs to the technical field of liquid ammonia safe treatment, and particularly relates to an integrated liquid ammonia consumption and conversion device.The integrated liquid ammonia consumption and conversion device comprises a shell, and is characterized in that a main heat exchanger is arranged in the shell, a cavity is formed in the center of the main heat exchanger, a liquid ammonia inlet pipeline is connected with a main pipeline extending into the cavity after being connected with a consumption water inlet pipeline so that mixing and heat exchanging can be integrated, the bottom of the main heat exchanger is connected with a cooling water inlet, and the upper portion of the main heat exchanger is connected with a cooling water outlet.The integrated liquid ammonia consumption and conversion device has the advantages that the liquid ammonia inlet pipeline goes deep in the cavity in the center of the spiral plate type heat exchanger after being connected with the consumption water inlet pipeline, a mixer in a traditional consumption device is integrated with the heat exchanger, liquid ammonia is absorbed and cooled synchronously, the whole device is smaller in size and higher in efficiency, the ammonia temperature at the mixing position is effectively controlled, and it is avoided that because liquid ammonia greatly dissipates heat when absorbed, damage and potential dangers are caused to the device.
Description
(1) technical field
The invention belongs to liquefied ammonia safe handling technical field, dissolve conversion system in particular to a kind of integration liquefied ammonia.
(2) background technology
Ammonia is a kind of material being widely used with various phase, and ammonia is extremely soluble in water and forms ammoniacal liquor. Ammoniacal liquor is a kind of important industrial chemicals, is also reagent conventional in chemical experiment. Ammoniacal liquor is the liquid of a water white transparency, has special intense stimulus stink, and ammoniacal liquor is in alkalescence, and the ammonia soln character extremely unstable of high temperature, the ammonia being dissolved in water can overflow from ammoniacal liquor so that the concentration of ammoniacal liquor reduces greatly.
Liquefied ammonia is higher to storage request because of safety reasons, need to be equipped with corresponding liquefied ammonia emergency treatment plant, liquefied ammonia is converted into ammoniacal liquor. Liquefied ammonia and water mixing process are strong exothermic process, strong heat release can gasify participate in mixing liquefied ammonia be gas ammonia, cause volume acutely to expand, and in hot ammoniacal liquor, ammonia more easily volatilizees, and causes ammonia loss by volatilization, be unfavorable for the storage of ammoniacal liquor.
Existing liquefied ammonia is dissolved device, mostly comprise jet mixer, static mixer, interchanger, tail gas absorber, pipeline and pepeline fittings, system is entered after being filtered from the liquefied ammonia of liquid ammonia storage tank outflow, a small amount of liquefied ammonia directly enters first step mixing tank and mixes with soft water, the ammonia soln of the rear high temperature of mixing enters first step interchanger and cools, ammonia soln after cooling enters second stage mixing tank and again mixes with a small amount of liquefied ammonia, now, the heat of second time mixing generation can be utilized in the interchanger of the second stage by liquid ammonia gasification, simultaneously, the temperature of high temperature ammoniacal liquor is by rapid reduction, ammonia soln after cooling flows out system, enter tank used for storing ammonia for subsequent use. so, heat exchange efficiency is very low, and absorption and the cooling of liquefied ammonia need proceed step by step, it is necessary to equipment volume relatively big, mixing place ammonia temperature cannot be effectively controlled, and when liquefied ammonia absorbs, equipment is easily caused bigger damage by a large amount of heat release.
(3) summary of the invention
The present invention is in order to make up the deficiencies in the prior art, it provides a kind of efficiency height, liquefied ammonia absorb with lower the temperature synchronously carry out, floor space is little, security is high integrated liquefied ammonia dissolves conversion system.
The present invention is achieved through the following technical solutions:
A kind of integration liquefied ammonia is dissolved conversion system, comprise shell, it is characterized in that: in described shell, be provided with main heat exchanger, main heat exchanger center is provided with cavity, the mixing that has been connected with the supervisor road stretching into cavity after being connected with water inlet pipeline of dissolving of liquefied ammonia inlet pipeline is integrated with heat exchange, being connected with entrance of cooling water bottom main heat exchanger, main heat exchanger top is connected with cooling water outlet.
Ammoniacal liquor outlet it is connected with bottom described main heat exchanger.
Described main heat exchanger top is connected with venting port.
Described supervisor road is provided with some apertures.
Described main heat exchanger is spiral-plate exchanger.
The invention has the beneficial effects as follows: liquefied ammonia inlet pipeline gos deep into spiral-plate exchanger center cavity after being connected with water inlet pipeline of dissolving, achieve tradition mixing tank in equipment of dissolving integrated with interchanger, the absorption of liquefied ammonia synchronously carries out with cooling, make whole equipment volume less, efficiency is higher, mixing place ammonia temperature is effectively controlled, and avoids damage and potentially dangerous that when liquefied ammonia absorbs, equipment is caused by a large amount of heat release.
(4) accompanying drawing explanation
Below in conjunction with accompanying drawing, the present invention is further illustrated.
Accompanying drawing 1 is the structural representation of the present invention;
In figure, 1 shell, 2 spiral-plate exchangers, 3 cavitys, 4 liquefied ammonia inlet pipelines, 5 dissolve water inlet pipeline, 6 supervisor roads, 7 entrance of cooling water, 8 cooling water outlets, 9 ammoniacal liquor outlets, 10 venting ports, 11 apertures.
(5) embodiment
Accompanying drawing is a kind of specific embodiment of the present invention. This embodiment comprises shell 1, it is provided with main heat exchanger in shell 1, main heat exchanger center is provided with cavity 3, liquefied ammonia inlet pipeline 4 mixing that has been connected with the supervisor road 6 stretching into cavity 3 after being connected with water inlet pipeline 5 of dissolving is integrated with heat exchange, being connected with entrance of cooling water 7 bottom main heat exchanger, main heat exchanger top is connected with cooling water outlet 8. Ammoniacal liquor outlet 9 it is connected with bottom main heat exchanger. Main heat exchanger top is connected with venting port 10. Supervisor road 6 is provided with some apertures 11. Main heat exchanger is spiral-plate exchanger 2.
The integrated liquefied ammonia of the present invention is adopted to dissolve conversion system, liquefied ammonia is flowed into the supervisor road 6 of spiral-plate exchanger 2 respectively with water of dissolving by liquefied ammonia inlet pipeline 4 and water inlet pipeline 5 of dissolving, carrying out being thoroughly mixed to form certain density ammoniacal liquor in spiral-plate exchanger 2, ammoniacal liquor exports 9 inflow ammoniacal liquor pond or ammoniacal liquor storage tanks by ammoniacal liquor after being down to normal temperature; Certain space is left at spiral-plate exchanger 2 center, liquefied ammonia inlet pipeline 4 stretches into spiral-plate exchanger 2 center cavity 3 with water inlet pipeline 5 of dissolving after being connected, achieve tradition mixing tank in equipment of dissolving integrated with interchanger, the absorption of liquefied ammonia synchronously carries out with cooling, make whole equipment volume less, efficiency is higher, and mixing place ammonia temperature is effectively controlled, and avoids damage and potentially dangerous that when liquefied ammonia absorbs, equipment is caused by a large amount of heat release. Recirculated cooling water enters in spiral-plate exchanger 2 by entrance of cooling water 7, after carrying out abundant heat exchange with the ammoniacal liquor in spiral-plate exchanger 2, flows into recirculated water supervisor road through cooling water outlet 8; The ammonia produced in this process can be discharged from venting port 10.
