Description
Technical field
This utility model relates to diesel engine vent gas purification techniques field capable of washing, particularly one can be with NOx, CO, HC, PM(black smoke in purification of diesel tail gas) etc. the purifier capable of washing of harmful components.
Background technology
Along with deepening continuously of China's economic transition, the demand of diesel engine is gradually increased by society, and meanwhile country is more and more stricter for the requirement in terms of the regulation of motor vehicle exhaust emission.At present, the purification techniques relying solely on electromotor self has not reached the requirement of country's relevant laws and regulations, so continuously improving diesel engine vent gas purification techniques to become extremely urgent.Current diesel engine vent gas purification techniques is the mode using DOC+POC mostly, and this technology exist a risk be exactly POC carrier be susceptible to blocking, causing exhaust back pressure to rise rapidly, diesel engine output power degradation ultimately results in diesel engine and cannot run well, the most flame-out.
Utility model content
The purpose of this utility model is to provide the diesel engine exhaust gas purification device that a kind of air-flow is uniform, be easy to clean, can be monitored by temperature parameter and pressure parameter gas discharge.
For achieving the above object, diesel engine exhaust gas purification device capable of washing of the present utility model includes that tubular shell, tubular shell include air intake casing and the exhaust casing linked together by flange arrangement, is connected with clip at flange arrangement；
Being provided with anemostat in air intake casing, the import of anemostat is as the import of air intake casing；Some diffusion holes it are evenly distributed with on the tube wall of anemostat；It is provided with DOC carrier in air intake casing, in exhaust casing, is provided with POC carrier；
The radial surface of exhaust casing connects at POC carrier delivery pipe, and the axial end portion of exhaust casing is provided with access hole, is provided with end cap at access hole, and end cap is linked together by screw bolt and nut with exhaust casing；Housing is provided with temperature sensor and differential pressure pickup, temperature sensor and differential pressure pickup and is all connected with a monitoring means.
Described monitoring means is integrated circuit or PLC or single-chip microcomputer；Described monitoring means connects acousto-optic alarm.
This utility model is compared with prior art, it is simple to cleans and can be discharged by temperature parameter and pressure parameter monitoring gas.User only need to pull down clip, twist off nut and open end cap and can be carried out the carrier of blocking, convenient to operation and maintenance cost is low, and can be prevented effectively from purifier and block, it is ensured that diesel engine safety operates reliably.This utility model issued the user with early warning before carrier blocks, and facilitated user to take emergency measures in advance, thus ensured that diesel exhaust gas back pressure, in rated range, ensures the safe handling of diesel engine.The structure of anemostat ensure that air-flow uniformly through DOC carrier and POC carrier, thus can improve tail gas clean-up effect.

Detailed description of the invention
As shown in Figure 1, Figure 2 and Figure 3 (in Fig. 1, direction shown in arrow is airflow direction), diesel engine exhaust gas purification device capable of washing of the present utility model includes tubular shell, tubular shell includes air intake casing 9 and the exhaust casing 10 linked together by flange arrangement 11, clip 4, clip 4 mounting flange structure 11 it is connected with at flange arrangement 11.
Being provided with anemostat 8 in air intake casing 9, the import of anemostat 8 is as the import of air intake casing 9；Being evenly distributed with some diffusion holes 12 on the tube wall of anemostat 8, each diffusion hole 12 all connects the cavity in air intake casing 9；It is provided with DOC carrier 5 in air intake casing 9, in exhaust casing 10, is provided with POC carrier 3；
The radial surface of exhaust casing 10 connects at POC carrier 3 has delivery pipe 13, the axial end portion of exhaust casing 10 to be provided with access hole, is provided with end cap 1 at access hole, and end cap 1 is linked together by bolt 14 and nut 2 with exhaust casing 10；Housing is provided with temperature sensor 6 and differential pressure pickup 7, and temperature sensor 6 is all connected with a monitoring means with differential pressure pickup 7.Described monitoring means is integrated circuit or PLC or single-chip microcomputer；Described monitoring means connects acousto-optic alarm.
Wherein, flange arrangement 11, clip 4, audible-visual annunciator, monitoring means, DOC carrier 5 and POC carrier 3 are existing conventional equipment, and concrete structure no longer describes in detail；Monitoring means and audible-visual annunciator not shown in Fig. 1.
It is coated with noble metal catalyst on DOC carrier 5 and POC carrier 3, can be by NOx, CO, HC, PM(black smoke in tail gas by the catalysis of catalyst under conditions of 300 ~ 400 DEG C) it is converted into the innocuous substances such as N2, CO2, H2O.
As shown in Figures 1 to 4, during use, gas is diffused after entering this utility model under the effect of anemostat 8 by diesel engine vent gas, it is easy to air-flow uniformly through DOC carrier 5 and POC carrier 3, high temperature gas flow can occur chemical reaction when by DOC carrier 5 and POC carrier 3 under the effect of supported catalyst, by harmful components NOx in tail gas, CO, HC, PM(black smoke) it is converted into the innocuous substances such as N2, CO2, H2O, the tail gas after process is discharged from delivery pipe 13.While utility model works, temperature sensor 6 and differential pressure pickup 7 can record the pressure reduction before and after the temperature of air-flow and carrier and be sent to monitoring means.If carrier in use engenders stopping state, before completely plugged, temperature or pressure reduction will be abnormal, and audible-visual annunciator will be sounded a buzzer sound make its display lamp shown in red, reminds the user that and safeguards this utility model in advance.Now operator only need to pull down clip 4, twist off nut 2 and open end cap 1 and can be carried out the carrier of blocking, convenient to operation and maintenance cost is low, and can be prevented effectively from purifier and block, it is ensured that diesel engine safety operates reliably.
