Grain is mainly certain heavy metal compounds, lead compound, black smoke and mist of oil, has seriously polluted the environment, influences people's health, special
It is not some carbonaceous particles, the self purification in the various channels of pulmonary lesion intrapulmonary of the deep enough people of energy, to make other compounds
Play carcinogenesis；In order to meet the discharge standard in China, it is necessary to use tail gas clean-up technology, reduce the discharge of particulate matter.
Summary of the invention
In order to overcome the shortcomings in the background art, originally practical newly to disclose a kind of farm machinery exhaust particulate object filtering
Device can reduce the discharge of agricultural machinery exhaust particulate object.
For achieving the above object, the utility model adopts the following technical solution:
A kind of farm machinery exhaust particulate object filter, comprising the interior shell for having cavity, one end of the shell is equipped with tail
Gas import, the other end are equipped with offgas outlet；The shell inner exhaust gas entrance is equipped with air flow distribution tube closed at one end, the gas
Another end opening of flow point stringing is simultaneously connected to inlet exhaust gas, and the side wall of the air flow distribution tube is equipped with several air inlets；The shell
From inlet exhaust gas to being equipped at intervals with several foamed ceramic panels between offgas outlet in the cavity of body, several foamed ceramic panel edges
It is sealed respectively at inner walls face contact.
Further, the foamed ceramic panel is open-celled ceramic.
Further, the porosity of the foamed ceramic panel is 20%~50%.
Further, the foamed ceramic panel with a thickness of 2cm~5cm.
Further, the shell is tube structure.
Further, the shell inward at both ends is shunk in a circular table shape.
Further, the inlet exhaust gas and offgas outlet are respectively equipped with connecting flange.
Further, several foamed ceramic panel uniform intervals settings.
Further, several air inlets are evenly spaced on.
Further, the foamed ceramic panel is aluminium oxide or silicon carbide material.
Due to the adoption of the technical scheme as described above, the utility model has the following beneficial effects:
Farm machinery exhaust particulate object filter disclosed by the utility model, by the inlet exhaust gas and agricultural machine of the filter
The exhaust port of tool is correspondingly connected with, so that the filter is passed through in flowing when exhaust emissions, and has stomata by setting side wall
Air flow distribution tube, tail gas is broken up and enable tail gas it is more uniform by the filter so that tail gas with every piece
The section of foamed ceramic panel comes into full contact with, and reaches better particulate matter filter effect；Foamed ceramics has porosity height, specific surface
Product is big, anti-thermal shock, high temperature resistant, resistant to chemical etching and good mechanical strength and filtering absorption property, by foamed ceramic panel interval
It is distributed in filter, level interception is carried out to the particulate matter in tail gas and traps, effectively reduce the particulate matter of exhaust emissions
Content improves the quality of environment；The void density and thickness of the foamed ceramic panel can be according to the power of farm machinery engine
It adjusts, the quantity of foamed ceramic panel is determined according to capacity, corresponding numerical value is a liter number, and one piece of foamed ceramic panel can
Filter 1 liter of number.
Detailed description of the invention
Fig. 1 is the schematic diagram of the utility model.
In figure: 1, inlet exhaust gas；2, air flow distribution tube；3, shell；4, foamed ceramic panel；5, offgas outlet.
Specific embodiment
By the following examples can the detailed explanation present invention, open the purpose of this utility model is intended to protect this reality
With all technological improvements in novel range, the utility model is not limited by the following examples:
The farm machinery exhaust particulate object filter in conjunction with described in attached drawing 1, comprising the interior shell 3 for having cavity, the one of shell 3
End be equipped with inlet exhaust gas 1, the other end be equipped with offgas outlet 5, as needed, shell 3 be tube structure, in addition, 3 both ends of shell to
Contract is in a circular table shape namely the cavity section of the shell 3 is greater than corresponding inlet exhaust gas section, guarantees that tail gas more large area connects
While touching foamed ceramic panel 4, also tail gas flow velocity can be reduced by increasing promoting menstruation, extend tail gas and foamed ceramic panel 4
Time of contact increases the efficiency of filtering；Air flow distribution tube 2 closed at one end, air flow method are equipped at 3 inner exhaust gas import 1 of shell
Another end opening of pipe 2 is simultaneously connected to inlet exhaust gas 1, and the side wall of the air flow distribution tube 2 is equipped with several air inlets, when tail gas is from tail
When gas import 1 enters, can be flowed out from the stomata of 2 side wall of air flow distribution tube, which break up tail gas, make tail gas from
The port of path becomes more uniform when entering the cavity of major diameter, so that the section of tail gas and every piece of foamed ceramic panel is abundant
Contact, reaches better particulate matter filter effect, it is preferred that several air inlets are evenly spaced on；
It makes pottery in the cavity of shell 3 from inlet exhaust gas 1 to several foamed ceramic panels 4, foam is equipped at intervals between offgas outlet 5
There is porcelain the porosity height, large specific surface area, anti-thermal shock, high temperature resistant, resistant to chemical etching and good mechanical strength and filtering to adsorb
Foamed ceramic panel 4 is spaced apart in the filter by performance, is carried out level interception to the particulate matter in tail gas and is trapped, has
Effect reduces the particle content of exhaust emissions, improves the quality of environment；As needed, foamed ceramic panel 4 is open-celled ceramic, excellent
