DIN 19606:2010-09 Foreword This standard has been prepared by Working Committee NA 119-04-02 AA Wasseraufbereitung of the Normenausschuss Wasserwesen (Water Practice Standards Committee). As a result of developments in chlorinator technology, new chlorinators us

6、ed in public water supply systems or public swimming baths no longer require lines and parts to be under pressure from chlorine gas. Instead, the whole system, from the point of connection to the chlorine gas cylinder to the injector, operates on the vacuum principle, hence the term “vacuum chlorina

7、tor”. For chlorinators still comprising lines and parts under chlorine gas pressure, reference is made to the more stringent requirements specified in the German Ordinances on industrial safety and health and on hazardous substances (Betriebssicherheitsverordnung and Gefahrstoffverordnung). The risk

8、 assessment carried out on the basis of these ordinances then results in the necessity to modify the plant. Amendments This standard differs from DIN 19606:2006-06 as follows: a) the scope has been given more in detail; b) an automatic switchover facility is provided as an option in the case of two

9、or more connected chlorine gas containers; c) the flow control of the sprinkler system with warning device and the presentation of the sensor for chlorine warning devices in the plant room have been deleted; d) specifications relating to further technical details and Figures 1 and 2 have been revise

10、d, and Figure 3 has been included; e) specifications relating to the withdrawal of chlorine gas and the operation of chlorinators have been amended; f) information relating to the installation and operation of chlorinators have been given more in detail and a distinction has been made between the re

11、quired components and the additional devices required in accordance with BGV D 5/GUV-V D 5 or BGR/GUV-R 108; g) other forms of chlorine gas removal devices have been taken into account.

12、to chlorinators used for treatment of water for use as drinking water, swimming pool water, spa bath water and industrial water, and for treating cooling water and waste water. This standard is applicable only to chlorinators operating by the indirect method. For plant provided with chlorine evapora

13、tors this standard applies to the vacuum regulator connected to the evaporator unit and all equipment downstream of this regulator. 2 Normative references The following referenced documents are indispensable for the application of this document.

16、tors shall be used for chlorinating drinking water, swimming pool water and spa bath water by the indirect method. These chlorinators operate under a vacuum which is produced by an injector and extends directly to the chlorine container valve. The structural requirements and safety devices for chlor

17、ine gas rooms are governed by BGV D 5/GUV-V D 5 or BGR/GUV-R 108. Vacuum chlorinators shall be equipped with the devices specified in 3.2 (see Figure 1). Additional devices required in accordance with BGV D 5/GUV-V D 5 or BGR/GUV-R 108 are listed in 3.3 (see Figure 1). Figures 2 and 3 show design ex

19、nominal outlet pressure control (10c), immediately upstream of the chlorine gas container shut-off valve (3). The vacuum control valve (vacuum regulator) shall shut-off automatically in case of a vacuum drop. If a chlorinator is operated with several 1) Source of supply: Responsible Unfallversicheru

20、ngstrger (Statutory accident insurance companies) (Internet: http:/www.arbeitssicherheit.de). 2) Source of supply: Responsible Unfallversicherungstrger (Internet: http:/regelwerk.unfallkassen.de). 4 “DIN 19606:2010-09 chlorine gas containers, a chlorine gas inlet and slam shut valve shall be provide

21、d for each container. When using chlorine drums, a heated liquid trap shall be provided downstream of the vacuum control valve. 3.2.2 Pressure gauge (4a) to indicate the pressure for every chlorine gas container. The pressure in chlorine gas containers is not a function of the filling quantity but o

22、f the chlorine temperature. The pressure gauge can also be equipped with a device to indicate when the chlorine gas container is empty. 3.2.3 Filter used to retain solid impurities in the chlorine gas, to be mounted upstream of the chlorine gas inlet and slam shut valve (usually a filter is part of

23、the chlorine gas inlet and slam shut valve with vacuum control valve). 3.2.4 Safety relief valve (6): Safety device used to prevent the build-up of pressure in the vacuum line. The exhaust line of this device is usually provided with an adsorption device (7) (e.g. a filter packed with ceramic filler

24、 material and activated charcoal grain) and should be installed near the sensor (20) of the chlorine gas alarm device (19). 3.2.5 Vacuum safety valve (8) used to prevent pressure in the vacuum line (5) towards the injector (12). This valve is only required if the injector (12) is located outside the

25、 chlorine gas storage room. 3.2.6 Meter (10a) used to measure the chlorine gas mass flow in g/h or kg/h. The chlorine gas mass flow shall be indicated using a scale that is as long as possible and having a resolution of 5 % of the full scale value. 3.2.7 Valve (10b) for open-loop or closed-loop cont

26、rol of chlorine gas mass flow, the volume feed being set manually by means of an adjusting knob or by an electric servomotor. This can be done depending on the volumetric flow rate of the water and/or the chlorine concentration of the water. 3.2.8 Nominal outlet pressure control (10c) for ensuring c

27、onstant chlorine gas mass flow. 3.2.9 Non-return valve (11a) (resistant to chlorine water, non-positive) to prevent ingress of water into those parts of the chlorinator carrying chlorine gas. 3.2.10 Injector (12) for generating the vacuum and dissolving the chlorine gas in water. 3.2.11 Shut-off val

28、ve (15) for the service water (14). The service water of the chlorinator can also be released using an additional electro-pneumatic valve (18a) or a forcing pump to increase the pressure of the service water (14) in connection with an anti-siphon injector. 3.2.12 Solids separator (16) for the servic

29、e water (14) with pressure gauge or gauge for measuring the volume flow of the service water. 3.2.13 Non-return valve (11b) (resistant to chlorine water) installed immediately upstream of the injector. 3.2.14 Injection of chlorine solution (13) by shut-off valve (13a). Depending on the pressure cond

30、itions, another non-return valve or pressure retaining valve may be required. 3.2.15 Heating (26), thermostatically controlled. 3.3 Additional devices required in accordance with BGV D 5/GUV-V D 5 or BGR/GUV-R 108 3.3.1 Chlorine gas removal device, e.g. sprinkler system with service water (23), serv

Design and execution of the chlorine gas removal device is not dealt with in DIN 19606, but is governed by BGV D 5/GUV-V D 5 or BGR/GUV-R 108. 3.3.2 Chlorine gas

Only about 1 % of the

38、original mass of chlorine can be withdrawn continuously in gaseous form per hour from the chlorine container (e.g. 650 g/h from a chlorine cylinder containing 65 kg of gas). If a larger quantity per hour is withdrawn, the chlorine will cool down because of the increased heat removal, thus resulting

39、in a lower feed capacity (outward signs: range from the condensation of water to the icing of the chlorine gas container). In order to avoid this, a number of chlorine containers or larger containers shall be connected. Because of the heat requirement during withdrawal of chlorine, the room is to be

40、 heated. The permissible temperature on the surface of the chlorine gas container shall be not less than 15 C and shall not exceed 50 C. Large quantities of chlorine gas mass flows in the range of more than 30 kg/h should preferably be taken in liquid form from chlorine gas containers and then conve

41、rted into gas in special chlorine evaporators. Liquefied chlorine shall not be trapped between shut-off valves without the possibility of expansion. Where two or more chlorine gas containers are connected, an automatic switchover can be provided to ensure continuous chlorination without interrupting

42、 the chlorine supply. As soon as the container or containers are empty, the system automatically switches over the supply from the empty container(s) to the full one(s) (see Figures 2 and 3). It shall be ensured that the maximum quantity of chlorine needed (e.g. for shock chlorination) can be taken

43、from all the containers that are connected. It is not necessary to provide a switchover facility if the system operates taking the chlorine gas from all the containers in turn and with the required number of reserve containers on standby (see Figure 1). 7 DIN 19606:2010-09 Figures 1, 2 and 3 are fun
