Abstract
ABSTRACT OF THE DISCLOSURE
A device for the safe processing of all concentrations of gaseous mixtures using a thermal recombinator in a compact construction. For this purpose, a recombinator, which is comprised of a metallic housing and deviation surfaces arranged therein is inductively heated. The inlet piping for the hydrogen-enriched gaseous mixture and the outlet piping for the hydrogen-poor gaseous mixture are joined by means of a three-way valve. The third outlet of the safety valve conducts most of the flow of the hydrogen-poor gaseous mixture back to the containment. A requisite amount of hydrogen-poor gaseous mixture is conducted by means of the three-way valve to dilute the gaseous mixture coming from the containment, so that the hydrogen content of the gaseous mixture going to the recombinator remains below the combustion level.

A DEVICE_FOR REMOVING HYDROGEN GAS ~ROM THI~ CONTAINMENT
OF A NUCLEAE~ RE~CTOR PLANT
BACKGROUND
The present invention relates to nuclear reactors and more particularly to -5a device for removing hydrogen gas from the containment of a nuclear reactor piant by using a thermal recombinator, which is comprised of a metallic housing and deviation surfaces arranged therein for the flow of gas and which has an inlet piping for the hydrogen enriched gas mixture as well as an outlet piping for the hydrogen-poor gas mixture.
10Such a device has been described by the publication "Hydrogen Recombiner .
System" of the Rockwell Company under the publication No. 523K-20 Rev.
8/79. In this system two electrical heating elements are placed in an insulatlngspace. The gas mixture enriched with hydrogen led off from the containment [
flows within the space in a large tubular scroll case. The gaseous mixture is F::
15heated above the hot air in the space and then enters the reaction chamber also placed within the space. The gaseous mixture, which is now hydrogen-poor --leaves the insulated space by means of a pipe and after transferring its residual heat to a heat exchanger, again enters the containment. This type of heating requires a large floor space. In addition, for reasons for saEety, the device can 20only be operated if the hydrogen content of the gaseous mixture introduced is less than the concentration above which explosion may occur, i.e., approximately four volume percent.
The present invention therefore takes up the problem of producing a device of the type known initially9 which has a compact heating unit and which permits 25processing all gas mixture concentrations without danger. ~`

SUMMARY OF THE INVENTION
This problem is solved according ~o the present invention by inductively heating the walls of the housing and the deviation surfaces and by connecting the inlet piping for the hydrogen-enriched gaseous mixture to the outlet piping -S for the hydrogen-poor gaseous mixture by means of a three-way valve, whose ---third outlet conducts a portion of the hydrogen-poor gaseous mixture to the containment.
~y means of inductive heating, which does not require a great deal of space, a uniform introduction of heat, with little heat loss, is achieved up to the deviation surfaces acting as a stationary mixer surface. The gaseous mixture introduced into the recombinator is reliably maintained below the critical limitof four volume percent hydrogen by diluting the hydrogen-enriched gaseous mixture with a partial flow of the hydrogen-poor gaseous mixture In the region of the three-way valve.
The housing of the recombinator is preferably formed as an elongated tube r ....
unit, which is surrounded at least partially by a water-cooled induction coil.
In order to increase the input of heat, the region of the housing walls ,L":,:,:surrounded by the induction coil is reinforced in its construction and the deviation surfaces contact the inner surface of the walls in a type of friction 20 connection. Such an effort is obtained by welding the deviation surfaces to athick-walled piece of tubing and forming the friction connection between the - -peripheral side of the piece of tubing and the inner side of the housing walls.
According to a preferred configuration of the device, the gas flowing into the connecting pipe between the three-way valve and the containment as well 25 as into the inlet piping in the region between the containment and a recuperating heat exchanger is maintained, preferably by means of a supplemental heating unit at a temperature which is higher $han the temperature prevailing in the containment. This measure has the advantage of preventing formation of condensate in the piping system and thus there is no __ ~

A hydrogen-enriched gaseous mixture, which has formed in an excessive 10 amount in the containment is removed from the containment 1 of a nuclear reactor plant, not shown in further detail, by means of blower 2 and inlet piping 3 and is fed into recombinator 4. Housing 5 of the recombinator is an elongated cylindrical tubular unit, which is closed semispherically at both of its ends. In the cylindrical section of the housing are placed deviation surf aces 6 of 15 stainless steel, which serve as stationary mixing surfaces. The upper half of the housing is inductively heated by water-cooled coil 7. In this way swirling flow is induced also by deviation surfaces 6 as well as by housing wall 8, so that a homogeneous temperature distribution is assured. Insulation 13 introduced on the cylindrical section of housing 5 protects the induction coil from too high a20 heat load. The self-heating of the induction coil is led off by means of cooling circuit 14. The cooling circuit is provided with checkpoints 15, 16, recuperating heat exchanger 17, cut-off armature 18 and control armature l9.

In the region oE induction coil 7, deviation surfaces 6 are welded to thick-walled piping piece 9, which enters into a -type of friction connection with itsperiphery extending to the inside of housing wall 8 and contacting this wall. Aneffective introduction of heat is achieved by this intimate connection. The upper half of the recombinator serves for heating up to the operational temperature of seven hundred to seven hundred fifty degrees Celcius. The time it takes for the complete reaction of the hot gaseous mixture in the lower half amounts to approximately one half (0.5) second. A homogeneous temperature distribution is achieved ~y the appropriate confi~uration of the deviation surfaces. With a flow rate of one hundred eighty cubic meters per hour (in the normal state), approximately fifty liters total volume of the recombinator is necessary in all for a total time of one second. This volume is achieved, for example, by housing 5, which is comprised of one and one half meter long tube of nominal width of twenty five centimeters. After combustion has been achieved, the now hydrogen-poor gaseous mixture leaves the recombinator via outlet piping 10. The necessary heating power of induction coil 7 is controlled by means of temperature checkpoint 11. The gaseous mixture gives up a part of its heat by flowing through recuperating heat exchanger 12. In this way the gaseous mixture flowing into inlet piping 3 is preheated. The gaseous mixture found in outlet piping 3 is cooled to sixty to sixty-five degrees Celcius in counterflow in recuperating heat exchanger 17. Control armature 19 placed in the cooling circuit for the induction coil, to which recuperating heat exchanger17 is connected, controls the flow-through quantity of coolant. The desired temperature of the gaseous mixture passing through heat exchanger 17 in counterflow can therefore be controlled in a simple way. ~he gaseous mixture cooled for the time being now reaches remote-controlled three-way valve 21.
From here most of the hydrogen-poor gaseous mixture flows through outlet 22 of the three-way valve and pipe-line 23 through flame arrester 34 and arrives back at containment 1. The remainder of the gaseous mixture goes through ::

gaseous mixture coming from the containment. The quant;ty of the gaseous mixture brought through connecting pipe 3a depends on the hydrogen content of the gaseous mixture coming from the containment. It is con~rolled in such a way by the three-way valve that the gaseous mixture reaching the recombinator 5 is always less than four volume percent hydrogen. A dangerous explosion is thus reliably preYented~ Flowmeter units 27, 38, pressure gau~e units 29, 30, 31, temperature sensors 32, 33, and flame arrester 34 are incorporated. Pipe 23 is heated by means of a not-shown supplementary heating unit in order to keep the gaseous mixture at a temperature of sixty to sixty-five degrees Celcius. In this10 way it is assured that no condensate can form in the gaseous mixture prior toreaching the containment. In addition, the region of the inlet piping 3 between containment 1 and recuperating heat exchanger 12 is provided with a supplementary heating unit, not shown. l he temperature of the gaseous mixture flowing therein is thus kept at a higher value than the temperature 15 measured within the containment. Just as for pipe 23, this measure will present the possibility of any incidence of highly radioactive condensate occurring outside the containment.
