Problems solved by technology

[0004] The disadvantage here is that electrical energy is required for heating
Furthermore, it is disadvantageous that replacement either entails an expensive modification of the electric heater or a replacement of the entire filter element including the heating device, since the filter has to be designed as a repair part

[0029] The filter element 1 has two grooves 2 and 3 on the outer side along its longitudinal extension, ie in a direction parallel to the central axis. The coolant hoses of the internal combustion engine can be inserted or snapped into the grooves 2 and 3 of the filter element 1 .

[0030] The filter element 1 is heated by means of the coolant hoses, not shown, snapped into the grooves 2 and 3 and prevents the liquid to be filtered from freezing.

[0031] The filter element 1 has two pipe connections 4 and 5 which serve as inflow and outflow for the liquid to be filtered.

[0032] The filter element 1 is designed asymmetrically and has a shoulder 6, so that the filter element 1 can only be mounted in a unique position figure 2 corresponding bracket 10. according to figure 2 The support 10 has two projections 11 and 12 in the lower part for this purpose.

[0033] Between the two projections 11 and 12 on which the shoulder 6 of the filter element 1 rests, the support has a...

Abstract

The invention relates to a filter element (1, 21) which is particularly used for filtering a liquid to be solidified and is particularly used for filtering a reducing agent for selective catalyctic reduction in an exhaust after-treatment device of an internal-combustion engine, wherein the filter element (1, 21) is provided with at least one gap (2, 3) and / or a containing part (22, 23). A pipeline heating the filter element (1, 21) is inserted or can be inserted into the gap and / or the containing part, wherein the pipeline guides the fluid with increased temperature so that the filter element (1, 21) can form a radiator.

Description

technical field [0001] The invention relates to a filter element, in particular for filtering a liquid to be solidified, in particular for filtering a reducing agent for selective catalytic reduction in an exhaust gas aftertreatment device of an internal combustion engine. Background technique [0002] In order to reduce nitrogen oxides in the exhaust gases of combustion plants, waste combustion plants, industrial plants and engines, ammonia or ammonia solutions such as so-called AdBlue are mixed into the exhaust gases. AbBlue is a synthetic 32.5% urea solution according to DIN 70070 for aftertreatment of exhaust gases in SCR catalytic converters. Here, nitrogen oxides (NOx) are reduced by approximately 90% by selective catalytic reduction (SCR). x ) emissions. Urea solutions such as AdBlue freeze at about -11°C. In order to ensure the operation of the metering system for injecting urea solutions such as AdBlue into the exhaust gas even at temperatures below this, system ...
