Description of drawings
The invention will be further described below in conjunction with drawings and Examples, in the accompanying drawing:
Fig. 1 is the paint waste gas pollution control and treatment system schematic of existing container or the single paint locker of special-purpose vehicle production line;
Fig. 2 is the paint waste gas pollution control and treatment system configuration schematic diagram of existing container or a plurality of paint lockers of special-purpose vehicle production line;
Fig. 3 is a paint locker paint waste gas pollution control and treatment system schematic of the present invention.
The specific embodiment
As shown in Figure 3, the paint waste gas pollution control and treatment system of paint locker of the present invention is as follows: arrange two above paint lockers 1 on a container or special-purpose vehicle production line as required, present embodiment is that example describes with 4 paint lockers 1.Each paint locker 1 connects the import of an one-level treatment facility 2, the outlet of each one-level treatment facility 2 is connected on the buffer container 6 then, need according to design, one or more secondary purification treating apparatus 4 (present embodiment is 3) are set, the import of each secondary purification treating apparatus 4 is connected on this buffer container 6, and atmosphere is led in the outlet 5 of each secondary purification treating apparatus 4.Buffer container 6 can adopt common structure shapes such as cuboid container, cylindrical container.
The outlet of one-level treatment facility 2 adopts pipeline 3 to be connected with buffer container 6.
According to the specific design needs, 2 outlets of one-level treatment facility can be connected with buffer container 6 respectively, are connected with buffer container 6 after also can being connected earlier respectively again.When secondary purification treating apparatus 4 is two covers when above, the import of secondary purification treating apparatus 4 can be connected with buffer container 6 respectively, is connected with buffer container 6 after also can being connected earlier respectively again.
By the specified waste gas discharge capacity of each paint locker 1 13 ten thousand steres/hour about calculate, if each paint locker 1 is equipped with a cover governing system separately, then need 4 cover disposal abilities 13 ten thousand steres/hour secondary purification treating apparatus 4.And in the actual production, owing to reason such as paint locker waste gas discharge capacity is inhomogeneous, the total displacement of 4 paint lockers usually 36 ten thousand steres/hour about, adopt paint locker of the present invention paint waste gas pollution control and treatment system, then only need 3 cover disposal abilities 13 ten thousand steres/hour the secondary purification treating apparatus get final product.So just save 1 cover treating apparatus, and saved the device space, reduced energy consumption.
The quantity of secondary purification treating apparatus 4 is considered to be configured according to combined factors such as system's exhaust-gas treatment amount, equipment cost, equipment occupation space.When adopting a cover secondary purification treating apparatus 4, system realized making live load evenly, energy saving of system, saving equipment investment, reduce the purpose of equipment occupation space.When adopting the above secondary purification treating apparatus 4 of two covers, system has also realized improving the purpose of functional reliability.
The control embodiment one of secondary purification treating apparatus 4:
According to the waste gas discharge capacity of buffer container 6, the unlatching quantity of Artificial Control secondary purification treating apparatus 4 is complementary the total work capacity of secondary purification treating apparatus 4 and the waste gas discharge capacity of buffer container 6.
The control embodiment two of secondary purification treating apparatus 4:
In order to measure the waste gas discharge capacity of buffer container 6; automatically control the unlatching quantity of secondary purification treating apparatus 4; flow sensor 7 is set measuring each exhaust gas entrance of buffer container 6 (also can on the connecting pipe 3 of the outlet of the outlet of each one-level treatment facility 2 or each one-level treatment facility 2 and buffer container 6); each flow sensor 7 is connected with system controller (not shown) signal, the unlatching and the shutdown of system controller control secondary purification treating apparatus 4.
When system controller detects the waste gas total flow that flows into buffer container 6 and does not match with the secondary purification treating apparatus of working 4 total work capacities by flow sensor 7, adjust the work capacity of the secondary purification treating apparatus 4 of working or the quantity of secondary purification treating apparatus 4, make the two coupling.When detecting the waste gas total flow that flows into buffer container 6 by flow sensor 7 when system controller greater than the total work capacity of the secondary purification treating apparatus of working 4, quantity is opened in system controller control secondary purification treating apparatus 4 increase work capacities or increase, and secondary purification treating apparatus 4 total work capacities of working are mated with the waste gas total flow that flows into buffer container 6; When system controller detects the waste gas total flow that flows into buffer container 6 less than the total work capacity of the secondary purification treating apparatus 4 of working by flow sensor 7, quantity is opened in system controller control secondary purification treating apparatus 4 minimizing work capacities or minimizing, and secondary purification treating apparatus 4 total work capacities of working are mated with the waste gas total flow that flows into buffer container 6.
System controller can adopt the common used in industry controller.
Secondary purification treating apparatus 4 total work capacities of working are meant with the waste gas total flow coupling that flows into buffer container 6:
1. but when the work capacity timing of secondary purification treating apparatus 4, both are equal substantially, and the promptly total work capacity and the deviation of waste gas total flow are in allowed band;
2. when the work capacity of secondary purification treating apparatus 4 is non-adjustable:
A. when the total specified capacity of the secondary purification treating apparatus of working 4 when flowing into the waste gas total flow of buffer container 6, it is no more than the specified capacity of a cover secondary purification treating apparatus 4 greater than amount;
B. when the total specified capacity of the secondary purification treating apparatus of working 4 when flowing into the waste gas total flow of buffer container 6, its less than amount in both deviation ranges that allow.
Above-mentioned paint waste gas pollution control and treatment system works as follows:
1. after one-level treatment facility 2 is handled the paint waste gas of paint locker discharge, be discharged into buffer container 6;
2. according to the waste gas total flow of buffer container 6, adjust the total work capacity of secondary purification treating apparatus 4 and the waste gas total flow of buffer container 6 and be complementary.
The adjustment of the work capacity that secondary purification treating apparatus 4 is total can manually be adjusted according to the method described above or system controller is adjusted automatically.
Technical solution of the present invention has realized following beneficial effect:
1. secondary purification treating apparatus live load is even, and the efficient height effectively reduces the energy consumption of whole waste gas pollution control and treatment system;
2. improve the utilization rate of secondary purification treating apparatus, reduced the quantity of secondary purification treating apparatus, saved equipment investment, reduced equipment occupation space;
3. when adopting the above secondary purification treating apparatus of two covers, system can be not out of service because of indivedual secondary purification treating apparatus faults, the functional reliability height.
