The way to protect the network of drinking water supply of the industrial enterprises and settlement from pollution

 

(57) Abstract:

Use: the method can be used in enterprises of medical, microbiological and other sectors of the chemical industry, consuming along with other sources of drinking water quality from a municipal supply for drinking and industrial purposes and in the production process which handle hazardous substances. The inventive method is based on the exclusion of backflow of water in the enterprise network when the pressure in the urban network. This is achieved by setting the input city water company and at each branch from it for production needs within company buildings non-return valves. This increases the reliability of protection by duplication check valves, creation of buffer zones on pipelines with pressure and other measures, in parallel, reverse valves fitted relay pressure difference before and after them. When a situation arises when the pressure after the return of the valve exceeds the pressure up to them, the relay generates pulses in the circuit of the electrical contacts, which are converted into light and sound signals-team, which manually or gradstudies under pressure, for example, compressed air. 2 Il.

The invention relates to the field of water supply of the industrial enterprises, in particular medical, microbiological and other sectors of the chemical industry, in the production process which handle hazardous substances, use along with other sources of drinking water quality of settlements to meet their needs in the industrial and drinking purposes.

Protection of the water supply network for domestic and drinking purposes from contamination in such enterprises at the present time by means of a so-called jet rupture, namely (see Fig.2) that water for drinking purposes comes from the city network 1 directly into the distribution network (outdoor and indoor) enterprise 2 industrial buildings 13, and for industrial needs through a separate branch in the accumulator tank 3 with a gap jet and automatically maintain the level therein controller 4. From the reservoir the water pump 5 is extracted and is served in a separate outdoor and indoor network 6 industrial water supply. Thus the company formed two separate systems in which bienia used artesian well.

The disadvantage of this method is, first, that his account liberalization is associated with large investments in the construction of the reservoir, pumping stations, outside separate networks, and secondly, it is associated with unnecessarily high power consumption head first extinguished in the tank, and then pump rises again, thirdly, the high costs of operation of the systems and, finally, the most basic thing for all the apparent reliability of the necessary protection it does not provide, because the development of networks, usually behind the development of production, artesian water is often just not enough, being forced to go to deviations from the "rules" are tapping directly into the network of households. drinking water supply to filter water for production needs, resulting in the conditions are in reality perebrosa harmful substances in network management.-drinking water supply of the enterprise and, of course, in the urban network with deep pressure drop the water flow stops on it.

The technical result of the claimed method is the exclusion of water backflow into the water system of the enterprise when the pressure in the urban network, for which (see Fig.1) place the insertion of the household.-pitavastatin buildings 13 on production needs are check valves 7, when the pressure drop in the city's network and the termination of the movement of water in the direction of consumers spontaneously closed, excluding the counter.

For latching when the water pressure after the non-return valves (from consumers) more than to the valves (from the source), improve the reliability of protection by duplication of check valves, the creation of buffer zones with excessive pressure and other measures in parallel with check valves fitted relay differential pressure 8. The pulses in the circuit of the electrical contacts, remove from the relay when triggered, is converted into an audio 9 and length 10 signals, which apparatchiks, leading process block valves 11 after the return valve, open the valve 12 on the lines, for example, compressed air, thereby creating a back pressure in the buffer zones between points "a" and "b", stop process relieves pressure from the side of the processing units.

All this, of course, can be accomplished if necessary by means of automation.

Thus, as is apparent from the foregoing, the proposed method with a high degree of reliability and protects the household.-p is vetvleniya inside buildings, duplicated a check valve installed at the input of water to the plant, creating with regard to buffer zones with pressure multi-stage protection. The lack of the necessity of building a parallel network of industrial water supply allows, without any restrictions to simultaneously address issues of production and households.-drinking water supply, thereby eliminating the motivation deviations from the rules with tie-ins with all the consequences.

The way to protect the network of drinking water supply of the industrial enterprises and settlement from contamination with harmful substances by preventing the reverse current of water in the enterprise network when the pressure in the urban network, involving the use of check valves and stop valves, characterized in that creates a multi-level network security, without disclosure of the conduits with different marks mouth and origins in tanks, for which the operation of check valves that are installed on the input of water to the plant and at all branches from it to water for production needs within industrial buildings, duplicated shutoff valves, create buffer zones with excess pressure, the parallel reverse valve for controlling the pressure difference before and after them, and connected with shut-off valve is closed and the compressed air in the BU - atmospheric zone when the pressure in the urban network.
