Abstract
The invention relates to an intelligent and detachable diesel engine tail gas particulate filter which is mainly composed of a gas filtering chamber, a sensor, a filtering core, a sealing cover, an intelligent analysis system and the like. The filter has a detachable top part and is connected to the tail part of an exhaust pipe after the filtering core is installed and the sealing cover is screwed tightly; the purification efficiency for harmful gases in the tail gas of the diesel engine can be improved greatly through strong adsorbability and strong filterability of a carbonized micrometer wood fiber material. The specific work state of the filtering core can be known in real time through monitoring, analysis and displaying of the intelligent analysis system; when the filtering core reaches to the limitation of the service life and needs to be replaced in time, an indicating lamp sends out a warning signal to remind an operator of replacing the filtering core. In addition, the filtering core is made of discarded wood corner materials, and the discarded wood corner materials after subjected to special machining form carbonized nanometer wood fibers with excellent purification performance; the replaced filtering core can serve as a fuel to realize repeated utilization of resource, so that the intelligent and detachable diesel engine tail gas particulate filter improves the utilization rate of the discarded resource and accords with the current green and environment-friendly social hotspot.
Description
Technical field: the present invention relates to a kind of diesel engine tail gas particle catcher, in particular, be that a kind of utilization has the charing Micro-wood Fiber of strong purifying ability as having of material for core diesel engine tail gas particle catcher detachability and intelligent analysis system, that compact structure is succinct.
Background technique: the diesel engines at present tail gas particle catcher is non intelligent, non-dismountable formula, dismounting that therefore can not implement device, the replacing of filter core; And as cordierite honeycomb ceramic, silicon carbide and the foamed ceramics etc. of main material for core, be non-renewable resources, and exist to fuel qualities have relatively high expectations, the effective time is short, the easy many inferior positions such as " poisonings " of catalyzer; In addition, the grain catcher price is higher, is directed to the present situation that China's diesel engine is prevalent in remote countryside, causes the universal development with diesel engine of grain catcher to be greatly limited.
Summary of the invention: intelligent detachable diesel engine tail gas particle catcher mainly partly is comprised of filter air chamber, suction tude, steam outlet pipe, sealing cover, sensing means and intelligent analysis system etc.Wherein filtering air chamber comprises: chamber body, sensor, filter screen, rubber pad etc.Air cell size is R=65mm, and h=160mm, its constituent material are the high-quality steel; The air chamber top is detachable, and has the bayonet socket that can be connected and sealed, and the tubulose that anterior, rear portion respectively has an interface to reduce gradually connects, and is respectively applied to into and out of gas; Connecting inside at two tubuloses has respectively a baroceptor, is used for measuring the back pressure of filter core; The tubulose connecting surface respectively is drilled with aperture, is used for winding displacement; Cylinder interior hollow is for the filter core of laying same size.The air chamber top is furnished with the lid with bayonet socket, and lid inside is embedded with silica gel ring in order to enhanced leaktightness.Intelligent analysis system mainly comprises single-chip microcomputer, sensing means, Cable Assembly system and display system, and sensing means is measured the back pressure of filter core, and numerical value is input in the single-chip microcomputer and analyzes, and analysis result outputs to display system, namely is positioned at the warning light on the control panel.
Description of drawings: Fig. 1 is detachable diesel engine tail gas particle catcher workflow diagram.Fig. 2 is air chamber sealing lid plane sketch.Fig. 3 is filter air chamber plane sketch.Fig. 4 is filter air chamber illustraton of model.Fig. 5 is sensor and single-chip microcomputer illustraton of model.
Embodiment: utilize the charing Micro-wood Fiber material of the process special processing process with good purifying property as the filter core of diesel engine tail gas particle catcher, place in the dismountable filter air chamber in top, screwing hermetic lid after device is finished, and will filter on the outlet pipe that air chamber is connected to diesel engine, to carry out the filtration of particle and absorption in the harmful gas in the tail gas.Baroceptor respectively is equipped with carrying out the measurement of filter core back pressure in both sides at the filter air chamber, and connects the external smart analytical system, and when back pressure surpassed 20kPa, the display lamp on the Diesel Engine Control panel will be luminous, reminds more renew cartridge of operator.Sealing cover adopts relatively firmly snap fit with being connected of filter air chamber, and is embedded with silica gel ring, with the enhanced leaktightness performance.
