DD140488A1 - TRANSPARENT CHANNEL PLANT FOR THE CHEMICAL PIPE CLEANING OF DRINKING AND WASTEWATER LINES - Google Patents

Abstract

The aim of the invention is to provide a mobile circulation device by which the chemical cleaning of the pipes constantly controlled and the consumption of cleaning medium can be controlled, the manual labor is low and the safety is significantly increased. The object is achieved in that one uses a mobile circulation system for chemical pipe cleaning of drinking and service water pipes, which consists of a mobile acid tank, which is provided with a vertical baffle so that an acidic chamber and a mud chamber arise. The acid and sludge chamber are connected to valves and pH-meter and supply lines with a delivery line and pump with pressure gauge and flexible auxiliary lines, to each of the tube seals are attached, connected to a ring line. - Fig.1 -

Description

Title:

Mobile circulation system for chemical pipe cleaning of drinking and roasting water pipes. '.

Applicant's invention:

The invention relates to a mobile circulation plant for chemical pipe cleaning of encrusted pipes for drinking and industrial water supply »

Characterization of the known technical solutions;

The well-known technology of chemical pipe cleaning of drinking water and service water works on the principle that acid of a certain concentration is poured into the encrusted, emptied from water pipe and is left there for a time unit. "The chemical reactions run, but uncontrolled and can not With decreasing acid concentration, the reaction rate of the chemical reaction decreases. A Control of the chemical reaction within the pipeline eg by changing the acid concentration, changing the flow rate, temporary use of compressed air, 'change in the flow direction is not possible in the known technology, since the pipe section to be cleaned during the cleaning process could not be monitored, so that the cleaning process often've had to be repeated and therefore rejected as uneconomical, became «

Object of the invention:

Goal ö.e: c invention is the creation of a mobile circulation device for cleaning pipes with the help of the cleaning medium in the pipe system can be performed in a continuous cycle and the running chemical

-SL-

184

Reactions within the pipe line can be constantly controlled to control the cleaning process by varying the seed concentration, flow rate or direction, temporary use of compressed air.

The device created should simultaneously serve as a means of transport for the cleaning medium and reduce the high manual work »

Explanation of the nature of the invention;

The object of the invention is to design a device such that the chemical tube cleaning; is carried out in a closed circuit, as well as constantly, controllable and controllable, whereby a high degree of cleaning of the tubes and achieved when handling the cleaning medium, the safety is significantly increased.

According to the invention this object is achieved in that one uses a mobile ümwälzanlage, in which irt an acid tank with a vertical immersion wall and therein, located. Filter nozzles is provided, a satire chamber and a mud chamber are present, the valves via valves with a delivery line consisting of suction, Hilfsleitung and. An evacuation and a pump and Rohrverschlüssen- via a second flexible auxiliary line with pipe closure rigid or flexible to the zui cleaning Tube route are connected.

Embodiments;

The device according to the invention is explained below using an exemplary embodiment »

In the accompanying drawing show

FIG. 1 '.

'Schematlsche illustration of the mobile circulation system for chemical pipe cleaning'

The device of Figure .1 shows acid tank i by baffle 5 with filter nozzles 4 separated in acid chamber 2 and Schlammkamraer 3> emptied by drain valve 6 and through the feed line 19 consisting of suction line 8, through valve 7 _S pump 9 with pressure gauge 10, through valve 11, Auxiliary line inlet 12, evacuation line 16, through-valve 17 »Through valve for filling with acid Through valve for compressed air connection 20»

The support line. 19 is connected by pipe closure with through valve 13 to the encrusted pipe section · By the flexible auxiliary line - return 14 with pH meter, a ring in the mud chamber 3 is closed.

For chemical pipe cleaning: use the mobile circulation system as follows:

In acid tank 1, the calculated amount of acid via passage valve 18 and 21 and suction line J pumped with 9 and subsequently recirculated in the circuit through the feed line 19 in the incrusted pipe section and the flexible auxiliary line - return 14 in the acid tank 1 The circulation is constantly on Pressure gauge 10 and observed on the pH meter 15. In the case of pH changes, acid is added to the acid tank via a through-valve 18, if necessary. «

209 184

Compressed air is briefly added at the passage valve 20. · Through the evacuation line; 16, the acid with pump 9 from the circulation in the acid tank 1. emptied. "

By the. The present device reduces the manual effort of chemical pipe cleaning, as a continuous flow in the closed circuit is produced by the pump 9, which is constantly controlled, controlled by changes in acid concentration, varying the speed and direction of plunger, temporary use of compressed air and constant review the pressure conditions.
