It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The present application will be described in detail below with reference to the embodiments with reference to the attached drawings.
The application is further described with reference to examples of embodiments shown in the drawings.
As shown in FIG. 1, an embodiment of the present application provides an exhaust treatment system for treating exhaust generated in a plurality of exhaust generating regions (not shown), the exhaust treatment system comprising: a plurality of dampers (e.g., damper 1, damper 2, damper 3), a control module 20, and an exhaust treatment module 10; the air valves have different numbers, the air valves correspond to the waste gas generation areas one by one, and the branch pipes 1a where the air valves are located are communicated with the waste gas treatment module 10; the control module 20 is configured to: the power of the exhaust gas treatment module 10 is determined from the number combination of the currently opened dampers.
Each branch pipe 1a where the air valve is located is used for pumping away the exhaust gas generated in the corresponding exhaust gas generation area and sending the exhaust gas to the exhaust gas treatment module 10. The control module 20 determines which dampers are currently open, i.e., knows which exhaust gas generating zones need to treat the exhaust gas, and each combination of exhaust gas generating zone openings corresponds to a power of exhaust gas treatment. For example, the power of the exhaust gas treatment module 10 is relatively large when the current exhaust gas generation region is open. Or, for example, if the current exhaust gas generation area is a device that generates a large amount of exhaust gas, the power of the exhaust gas treatment module 10 is relatively large. The specific exhaust-gas generation region which is open corresponds to how much exhaust-gas treatment capacity is required can be determined in advance by experiments. In this way, the power of the exhaust gas treatment module is dynamically adjusted and more targeted, and the efficiency of the exhaust gas treatment module 10 is increased.
Specifically, the dampers 1,2,3 may be electric dampers, which are opened or closed by the control of switches 4, 5, 6, respectively. The control module 20 determines which dampers are currently open by detecting the state of the switches 4, 5, 6.
In particular, one or more exhaust gas generating devices may be arranged within one exhaust gas generating area.
Optionally, the exhaust gas treatment module 10 includes an exhaust fan 11, the exhaust fan 11 is configured to extract the exhaust gas in the branch pipe 1a where the plurality of dampers are located, and the control module 10 is specifically configured to: and determining the exhaust air volume of the exhaust fan 11 according to the number combination of the currently opened air valves.
The control module 20 determines which dampers are currently open and thus how much exhaust air is currently needed. Specifically, the frequency of the frequency converter of the exhaust fan 11 may be controlled to control the exhaust amount.
Optionally, the exhaust gas treatment module 10 includes a water pump 12, the water pump 12 is configured to spray the exhaust gas, and the control module 20 is specifically configured to: and determining the spraying amount of the water pump 12 according to the number combination of the currently opened air valve.
The control module 20 determines which dampers are currently open and thus how much spray is currently needed. Specifically, the frequency of the frequency converter of the water pump 12 may be controlled to control the spraying amount.
Optionally, the control module 20 is further configured to: receiving a setting signal to set the power of the exhaust gas treatment module 10 corresponding to the number of the currently opened air valve.
That is, testing is performed for various combinations of opening and closing of all dampers to determine the optimum power of the exhaust treatment module 10 for each combination. I.e. it can treat the exhaust gas generated under the current combination and does not waste the power of the exhaust gas treatment module 10.
Optionally, the control module 20 comprises: programmable logic controllers (also known as PLCs). The cost of the PLC is low, and of course, the form of the control module 20 is not limited thereto.
Especially for the jewelry processing industry, the waste gas has low continuity and large concentration fluctuation, and if the spraying treatment capacity is adjusted by detecting the concentration of the waste gas in the pipeline, the following two defects are caused: 1. when the gas concentration is suddenly changed, the actual measurement data of the gas detector and the actual concentration in the pipeline are delayed greatly, so that the spraying amount of the waste gas is inconsistent with the required amount, and the instantaneous excessive emission risk exists; 2. the gas concentration fluctuates repeatedly, the rotating speed of equipment such as a fan and a water pump also fluctuates repeatedly, and the failure rate of the equipment is greatly increased.
In the scheme, the air valve is opened in place and closed in place to give signals, the air valve serves as a stable signal source, the PLC receives the air valve signals, and the power of the whole waste gas treatment unit is determined according to the pre-set fan frequency and the pre-set water pump frequency. The whole control operation is simple and convenient, and the working states of the signal input source air valve, the control module PLC, the fan and the water pump are relatively stable, so that the whole system is stable. In addition, according to the use example, the failure rate of the system caused by the control module is 0, compared with a system for controlling the power through an air flow meter and a waste gas detector, the stability of the system is greatly improved, and the actual energy-saving effect is considerable; in addition, the construction cost is low, and the later maintenance cost is low. The power of the waste gas treatment can be enough to deal with the sudden change of the waste gas amount through experimental debugging.
And (3) data comparison:
two identical production plants of the applicant are each provided with one exhaust gas treatment system, one of which uses the original exhaust gas treatment system (i.e. the exhaust gas treatment system operates at rated power once turned on) and the other of which uses the exhaust gas treatment system provided by the present application. According to the data statistics of the electric meter, from 2020.05.09 to 2020.08.31, the electricity consumption of the traditional exhaust system is adopted: 22888.3 KWh; adopt the exhaust-gas treatment system power consumption of this application: 12429 KWh; compared with the old system, the system has the advantages that the energy consumption is reduced by nearly 45 percent, electricity is saved for 10459KWh in four months, and electricity is saved for more than 3 thousands KWh every year.
Aiming at another production workshop, the traditional waste gas treatment system is changed into the waste gas treatment system provided by the application at the end of 7 months, the average power consumption is reduced from 1100KWh to below 700KWh, and the energy consumption is reduced by 36.4%.
It can be seen that the waste gas treatment system of this application can greatly reduce cost when carrying out exhaust-gas treatment to a plurality of waste gas production regions in the jewelry processing workshop. Namely, the plurality of exhaust gas generation regions include: a field for processing jewelry. The jewelry can be pearl, jade, noble metal jewelry and the like.
The off-gas generation zone is, for example, a hydrochloric acid blasting process zone. The hydrochloric acid frying process is to put the red gold into hydrochloric acid.
The waste gas generation zone is again, for example, a process zone for boiling aqua regia. The aqua regia boiling process is to dissolve gold tablet in aqua regia to obtain aqua regia.
The waste gas generation zone is again, for example, a process zone for boiling nitric acid. The nitric acid boiling process is to boil nitric acid and put gold into the boiled nitric acid to remove impurities.
The waste gas generation zone is again, for example, a process zone for boiling sulfuric acid. The sulfuric acid boiling process is to add gold into boiling sulfuric acid to remove impurities.
The relationship between the combination of the numbers of the opened dampers and the power of the exhaust gas treatment module 10 can be adjusted. For example, the interactive module 30 is provided to be in communication with the control module 20, and can display the power parameters (e.g., the amount of spraying) of the exhaust gas treatment corresponding to the current combination of the air valve numbers and change the power parameters according to the input command of the user. Thereby adapting to variable production environment.
The interaction module 30 comprises, for example, a touch display screen. The user operates on the touch display screen to trigger the touch display screen to output a change instruction to the control module 20, and the control module 20 adjusts the corresponding relationship between the number combination of the opened air valve and the power of the exhaust gas treatment module 10 after receiving the change instruction.
