Pressure compensated potable water chlorinator

Claim 1

A system for dissolving a compound in a liquid flowing through a channel comprising: diverting means in the channel for diverting a portion of the liquid into the system; solution storage means for storing a concentrated solution of the compound in the liquid; mixing means for mixing the concentrated solution from the solution storage means into the liquid in the channel downstream from the diverting means; tablet holding means for holding tablets of the compound so that the liquid entering from said diverting means will dissolve the tablets to produce the solution which flows to said solution storage means; flow regulating means for regulating the rate of flow of the liquid through the tablet holding means so that the amount of solution stored in the solution storage means will tend to be constant; pressure compensating means for adjusting the air and liquid pressures inside the system in response to changes in liquid pressure in the channel, said pressure compensating means comprises an air passageway and a pressure compensating tank, said tank being connected to the channel between the diverting means and the mixing means so that liquid may flow between the channel and the tank, with the tank having an air space near its top which is vented through the air passageway with an air space near the top of the tablet holding means.

Claim 6

A system for chlorinating water flowing through a main water pipe comprising: a first orifice in the main pipe for diverting part of the water flowing through the pipe into the chlorinating system; a solution chamber for storing chlorine solution before it flows into the main water line; a second orifice in the main water pipe, located downstream from the first orifice, for mixing chlorine solution from the solution chamber into the water flowing through the main pipe; a float in the solution chamber which rises and falls along with the level of liquid in the chamber; a tablet chamber containing a perforated basket for holding tablets of a water soluble chlorine compound, the tablet chamber being mounted above the solution chamber and drained into the solution chamber through an outlet in the bottom of the tablet chamber, and a vent passageway connecting the top portion of the solution chamber with the top portion of the tablet chamber; a valve which admits water diverted by the first orifice into said tablet chamber with the opening and closing of the valve being controlled by rising and falling movements of the float in the solution chamber so that the level of liquid in the solution chamber will tend to remain constant; and a pressure compensation tank with a large inlet near the bottom connected to the main water line between the first orifice and second orifice and with a vent hole near the top through which is connected by a vent passageway to the tablet chamber.

Claim 7

A system for chlorinating water flowing through a main water pipe comprising: a first orifice in the main pipe for diverting part of the water flowing through the pipe into the chlorinating system; a solution chamber for storing chlorine solution before it flows into the main water line; a second orifice in the main water pipe, located downstream from the first orifice, for mixing chlorine solution from the solution chamber into the water flowing through the main pipe; a float in the solution chamber which rises and falls along with the level of liquid in the chamber; a tablet chamber containing a perforated basket for holding tablets of a water soluble chlorine compound, the tablet chamber being mounted above the solution chamber and drained into the solution chamber through an outlet in the bottom of the tablet chamber, and a vent passageway connecting the top portion of the solution chamber with the top portion of the tablet chamber; a valve which admits water diverted by the first orifice into said tablet chamber with the opening and closing of the valve being controlled by rising and falling movements of the float in the solution chamber so that the level of liquid in the solution chamber will tend to remain constant; and a pressure compensation tank with a large inlet near the bottom connected to the main water line between the first orifice and second orifice and with a vent hole near the top through which is connected by a vent passageway to the tablet chamber.

Claim 11

A system for dissolving a compound in a liquid flowing through a channel comprising: diverting means in the channel for diverting a portion of the liquid into the system; tablet holding means for holding tablets of the compound so that the liquid entering from said diverting means will dissolve the tablets to produce a solution; mixing means for mixing the solution from the tablet holding means into the liquid in the channel downstream from the diverting means; flow regulating means for regulating the rate of flow of the liquid through the tablet holding means; pressure compensating means for adjusting the air and liquid pressures inside the system in response to changes in liquid pressure in the channel; said pressure compensating means comprises an air passageway and a pressure compensating tank, said tank being connected to the channel between the diverting means and the mixing means so that liquid may flow between the channel and the tank, with the tank having an air space near its top which is vented through the air passageway with an air space near the top of the tablet holding means.
