Abstract

An anti-freezing unit is designed to eliminate freezing of the condensate discharge pipe line 1 from a condensing boiler when discharging externally during adverse weather conditions, so as to keep the boiler in operation. The unit may utilise rock salt 4, or an equivalent material, situated on a non-corrosive mess grid 5 from where the condensate passes through it to form a non-freezing solution, which can be dispensed into a drain. Preferably, the unit further comprises a lid 2, a discharge void 3, a drip void 6, and a region 7 which retains the solution until it is discharged through an outlet pipe 8.

Description

TITLE:-Anti-Freezing Unit This invention relates to an anti-freezing unit.
When a gas or oil condensation central heating boiler is in operation, it creates condensate which has to be disposed of, otherwise it will not operate. This condensate when it is disposed of externally in a pipe line it is prone to freezing in adverse temperatures. This anti freeze unit when fixed in the condensate line before it is discharged externally helps to eliminate this, and therefore keeps the boiler in operation.
To over come this freezing problem, this invention proposes a Anti-Freezing Unit, which is fitted in the boiler condensate discharge line internally near the boiler. The waste tepid condensate passes through this unit and forms a solution which greatly reduces the risk of freezing. This solution is then discharged externally as specified by the boiler manufacturer.
The unit is easy and cheap to manufacture due to the rock salt or alternative material forming the solution being easily obtained. The unit should be of an in-obtrusive size to fit easily into a discharge line and can be of a variable size to cope with all manufactured boiler condensation output. The side of the unit could have a clear viewing panel opposite to the rock salt or equivalent material which on inspection can give an indication of the material remaining and if needed topped up to the level indicated.
An example of the invention will now be described by referring to accompanying drawings.
Figure 1 relates to the unit position.
Figure 2 shows a cross section of the unit.
In Figure 1.
Shows the condensation boiler (1) the condensate outlet pipe (2) the Anti-Freezing Unit (3) with the condensate pipe discharging through the top which filters through to the discharge outlet pipe (4) to an external or internal drain.
In Figure 2.
Shows a cross section through the Anti-Freezing Unit container, which will be an air-tight non-corrosive container of a size to suit the condensation boiler and will be mounted into the condensate discharge line near to the boiler (see figure 1).
(1) indicates the condensate discharge pipe from the boiler, which passes through the removable lid into the unit (2). The tepid discharge water passes through the pipe into the discharge void (3) and through (4) a rock salt or equivalent material which creates a soluble anti-freezing solution. The material should be of sufficient quantity to suit the boiler output, which will be variable due to the variable sizes. The material will be supported on a non-corrosive grid (5) and will allow the solution to pass through it into the drip void (6). (7) which retains the solutions until it is discharged into and through a bent air trapped outlet pipe (8) so that it can be discharged into a discharge drain. The pipe work into the unit and the unit should be air-tight to prevent carbon dioxide discharge which could be prevalent in the condensate discharge. (9) indicates the location of the clear viewing panel.

Claims (6)

1) This Anti-Freezing Unit will help to eliminate freezing of the discharge concentrate pipe line from the condensation boiler when discharging externally during adverse weather conditions and keep the boiler operable.
2) The Anti-Freezing Unit according to claim 1 will be made of a non-corrosive material of an unobtrusive size and fit easily into the internal discharge line.
3) The Anti-Freezing Unit according to claim 1 can easily be manufactured and non-mechanical and be of variable size to suit the boiler output.
4) The Anti-Freezing Unit according to claim 1 will have a rock salt or equivalent material that can be of variable quantity situated on a mess grid from where the condensate passes through it to form a non freezing solution that can easily and cheaply be maintained during adverse weather conditions.
5) The Anti-Freezing Unit according to claim 1 can easily fit into any condensate line whether gas or oil operated.
6) The Anti-Freezing Unit according to claim 1 will have air-tight removable lid to allow for easy cleaning and maintenance.S
