Abstract
The invention relates to an intelligent detachable type diesel engine tail gas particulate filter. The intelligent detachable type diesel engine tail gas particulate filter is characterized by being composed of a gas filtering chamber, a sealing cover, a filter element, a gas inlet pipe, an exhaust pipe, a sensor (1) and a single-chip microcomputer (2). The gas filtering chamber is in the shape of an open hollow tube, a clamping groove is formed in the top of the gas filtering chamber, and a gas inlet and an exhaust port are formed in the two sides of the gas filtering chamber; a clamping buckle is arranged in the sealing cover, and a high-temperature-resistant rubber ring is embedded in the sealing cover; the gas inlet pipe and the exhaust pipe are connected with the gas inlet and the exhaust port respectively of the gas filtering chamber respectively; the sensor is connected with the single-chip microcomputer through a high-temperature-resistant wire; holes are formed in the side of the gas inlet pipe and the side of the exhaust pipe so that the high-temperature-resistant wire can be arranged, and the holes are sealed through high-temperature-resistant paint; according to an intelligent analyzing system, when back pressure difference measured by the sensor reaches 20 kPa, the single-chip microcomputer makes an instruction. A traditional DPF is combined with an electronic control structure and a detachable structure; the adopted wood filter element is taken from waste wood; the waste gas filtering effect is guaranteed through an intelligent monitoring device.
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 material of strong purifying ability as diesel engine tail gas particle catcher detachability, that compact structure is succinct that has of worry core.
Background technique: diesel engines at present tail gas particle catcher (hereinafter to be referred as DPF) is non intelligent, non-dismountable formula, dismounting that therefore can not implement device, the replacing of filter core; And cordierite honeycomb ceramic, silicon carbide, foamed ceramics, braiding ceramic fiber and the wire gaze etc. of the main material for core of conduct, be non-renewable resources, and exist fuel qualities is required to comparatively strict, the used catalyst shortcomings such as easily " poisoning ", DPF cost be higher, this is greatly limited the universal and development of diesel engine of DPF.Therefore, the DPF that filter efficiency is high, fuel qualities is required to low, cheap, environmental protection is badly in need of in China.
Summary of the invention:
Problem to be solved by this invention is: the complex structure of existing DPF and non-dismountable, can not intuitive judgment filter core whether lose efficacy, filter core problem such as non-exchange after losing efficacy.
The technical solution used in the present invention is: a kind of intelligent detachable diesel engine tail gas particle catcher, it is characterized in that: described tail gas particle catcher, formed by filter air chamber, sealing cover, filter core, suction tude, outlet pipe, sensor (1), single-chip microcomputer (2), wherein filter air chamber and sealing cover assemblies Demountable, sensor and single-chip microcomputer connect to form intelligent analysis system.Described filter air chamber, is the uncovered tubulose of hollow, and draw-in groove is arranged at top, and both sides have suction port and relief opening; Described sealing cover, there is buckle inside, and embeds high-temperature resistant rubber circle, in order to strengthen the sealing of air chamber; Described filter core, its material is through planing, rubs silk, charing Micro-wood Fiber after treatment; Described suction tude and outlet pipe, be threaded connection with suction port and the relief opening of filter air chamber respectively, and suction port and exhaust ports are embedded with respectively filter screen, in order to ensure the shape of filter core; Described sensor is connected by high temperature resistant line with single-chip microcomputer; Described suction tude and outlet pipe, respectively in sidepiece perforate, in order to discharge high temperature resistant line, utilize heat resistance paint sealing after winding displacement, ensure the seal of air chamber; Described intelligent analysis system, in the time that the measured differential back of sensor reaches 20kPa, single-chip microcomputer is made instruction, and signal gives the alarm.
Beneficial effect: this invention by traditional DPF in conjunction with electronic control and dismountable structure, thereby greatly reduce cost; The wooden base filter core that it uses, is taken from discarded timber; And its intelligent monitoring and controlling device has more effectively ensured the filtering effect of waste gas.
Brief description of the drawings: Fig. 1 is detachable diesel engine tail gas particle catcher workflow diagram.Fig. 2 is filter air chamber front view.Fig. 3 is filter air chamber plan view.Fig. 4 is sealing cover plan view.Fig. 5 is sealing cover front view.Fig. 6 is filter air chamber and sensor, single-chip microcomputer location diagram.
Embodiment: utilize the charing Micro-wood Fiber material through special processing process with good purifying property as the filter core of diesel engine tail gas particle catcher, be placed in a dismountable filter air chamber in top, screwing hermetic lid after device completes, and filter air chamber is connected on the outlet pipe of diesel engine, to carry out the filtration of particle and absorption in harmful gas in tail gas.Baroceptor is respectively equipped with to carry out the measurement of filter core back pressure in both sides at filter air chamber, and connects external smart analytical system, and in the time that back pressure exceedes 20kPa, the tutorial light on Diesel Engine Control panel will be luminous, reminds more renew cartridge of operator.Sealing cover adopts snap fit with being connected of filter air chamber, and is embedded with silica gel ring, with enhanced leaktightness performance.
