Abstract
The invention discloses a tail gas emission filter. The filter comprises a base, an upper cover and a filter core, wherein the center of the upper cover is provided with a gas outlet interface connected with a gas outlet of the filter core; the upper cover and the base are in screwed connection and sealed by a sealing ring; the bottom part of the base is provided with a gas inlet interface; the bottom end of the filter core is closed and fixed by fixed screws; the filter core takes glass fiber as a filter medium; and the filter core is completely sleeved in the base to form a cavity. The filter is simple and small in structure, so that the filter is convenient for assembly and use and is easily maintained; and the glass fiber is used as the filter medium, the glass fiber has the advantages of high-temperature resistance, good gas permeability, big dust containing capacity and the like, and the filter core end face central gas inlet mode existing in the prior filter is changed into the filter core side face gas inlet of the filter, thereby improving the gas inlet efficiency and achieving extremely good filtering effect on tail gas of an automobile, particularly carbon particle impurities.
Description
Technical field
The present invention relates to a kind of environmental protection technology equipment, especially relate to a kind of tail gas emission filter that is used for the motor car engine discharge tail gas is carried out filtration, purification.
Background technique
Automobile is the very big means of transportation of a kind of use amount, bringing people simultaneously easily, a large amount of tail gas of its discharging, especially sweeping along the carbon particle impurity of a large amount of harmful gases that environment has been caused serious pollution, if untimely disposing, As time goes on, bring great harm can for people's life and health.At this situation, call the protection environment in order to respond country, people invent many vehicle exhaust emission-reduction technologies and equipment, as utilize pack into purified solution or utilize technology cleaning of off-gas such as catalyzer, play certain effect aspect reduction of discharging of cavity volume.But prior art equipment otherwise exist complex structure, bulky, install and use shortcomings such as inconvenience, difficult in maintenance, cost of production height, the filter core that adopts is that high-temperature behavior is poor, dust containing capacity is little, the papery of gas permeability difference or general fibre, therefore is unfavorable for applying.
Summary of the invention
The technical problem to be solved in the present invention provide a kind of simple in structure, easy to use, be easy to safeguard, tail gas emission filter that cost is low.
For solving the problems of the technologies described above, the present invention adopts following technological scheme: a kind of tail gas emission filter, comprise base, loam cake and filter core, it is characterized in that: the loam cake center is provided with the outlet side interface that joins with the filter core air outlet, loam cake and base are screwed connection, by the seal ring sealing, the base bottom is provided with the inlet end interface between loam cake and the base; The filter core bottom is fixing by retaining screw sealing, and filter core adopts glass fibre as filter medium, base with the whole big envelope of filter core interior and form a cavity.
Described filter core is provided with filter medium and the support that center hole forms as air inlet/outlet, the top cover that is circle structure, glass fibre by two to be formed, and top cover and support adopt exotic material; Glass fibre is around the support setting, and the glass fibre inner and outer surface is fixed-type by the filter paper cover, and two ends are fixed by two top seals, and top cover is fixed on the two ends of support, and whole filter core is the cylindrical hollow structure, is provided with pad on top cover.
Described seal ring is the O RunddichtringO.
The present invention is simple in structure, small and exquisite, thus easy to install, be easy to safeguard; Owing to adopt glass fibre as filter medium, advantage such as that glass fibre has is high temperature resistant, good permeability, dust containing capacity are big, and change filter in the past by the mode of filter core end face central air induction for by the air inlet of filter core side, improved intake efficiency, therefore can play splendid filtering effect vehicle exhaust especially carbon particle impurity.
Description of drawings
Fig. 1 is a generalized section of the present invention;
Fig. 2 is the structural representation of filter core of the present invention.
Among the figure, 1 is base, and 2 is loam cake, and 3 is the O RunddichtringO, and 4 is retaining screw, and 5 is filter core, and 6 is intake interface, and 7 are the interface of giving vent to anger, and 8 is top cover, and 9 is support, and 10 is the filter paper cover, and 11 is pad.
Embodiment
In the present embodiment, with reference to Fig. 1, described tail gas emission filter comprises base 1, loam cake 2 and filter core 5.Loam cake 2 centers are provided with the outlet side interface 7 that joins with filter core 5 air outlets, and loam cake 2 and base 1 are screwed connection, and by seal ring 3 sealings, base 1 bottom is provided with inlet end interface 6 between loam cake 2 and the base 1; Filter core 5 bottoms are fixing by retaining screw 4 sealing, and filter core 5 adopts glass fibres as filter medium, base 1 with filter core 5 whole big envelopes interior and form a cavity.Described seal ring 3 is the O RunddichtringO.
With reference to Fig. 2, described filter core 5 is provided with center hole by two to be formed as air inlet/outlet, the top cover 8 that is circle structure, filter medium and the support 9 that glass fibre is formed, and top cover 8 and support 9 adopt exotic material; Glass fibre is provided with around support 9, and the glass fibre inner and outer surface is overlapped 10 fixed-type by filter paper, and two ends are by two top cover 8 sealing and fixing, and top cover 8 is fixed on the two ends of support 9, and filter core 5 is the cylindrical hollow structure; On top cover 8, be provided with pad 11.
Using method of the present invention: inlet end interface 6 is connected suction tude, outlet side interface 7 connects steam outlet pipe, the tail gas of motor vehicle emission enters the filter cavity from suction tude, filter element 5 two ends can't enter gas, tail gas sees through filter paper cover 10 from filter core 5 sides and glass fibre passes through filter core 5, and under the effect of filter core 5, carbon particle impurity contained in the vehicle exhaust is all filtered out, make and discharge aerial tail gas free from admixture pollution, thereby can improve air quality greatly.
