Detailed Description
The invention will be further described with reference to examples of embodiments shown in the drawings.
The first embodiment is as follows: as shown in fig. 1, a recycle gas component balancing system comprises a gas feeding branch and a balancing branch. The air supply branch and the balance branch are connected in parallel to form a parallel system; the front end of the parallel system (i.e. the confluence part of the front ends of the gas sending branch and the balancing branch) forms a gas inlet end and is connected with a recovered gas source, and the rear end of the parallel system (i.e. the confluence part of the rear ends of the gas sending branch and the balancing branch) forms a gas outlet end and is connected with a subsequent process system.
An air supply regulating valve is arranged on the air supply branch. The balance branch is provided with a tank group formed by connecting a plurality of buffer tanks in series, a stop valve positioned between the air inlet end and the tank group, and a balance regulating valve positioned between the tank group and the air outlet end.
In the scheme, the volume and the number of the buffer tanks included in the tank group can be reasonably set according to the treatment gas amount and the fluctuation change of the content of a certain component in each period. In this embodiment, the balance branch includes three buffer tanks connected in series, and each buffer tank is a recovered gas having any component. When the components of the recovered gas fed into the recovered gas component balance system from the gas inlet end are lower than or higher than the components of the gas in the buffer tank, the recovered gas flowing through the gas feeding branch and the recovered gas stored in the buffer tank in the balance branch are reasonably mixed and then fed into a subsequent process system.
Further, in order to more reasonably mix the recovered gas, the recovered gas component balance system further includes a gas inlet component analyzer disposed at the gas inlet end (on-line analysis point a), a balance component analyzer disposed between the tank group and the gas outlet end (on-line analysis point B), a gas outlet component analyzer disposed at the gas outlet end (on-line analysis point C), and a controller (not shown in the figure). The controller is respectively connected with the gas inlet component analyzer, the balance component analyzer, the gas outlet component analyzer, the gas supply regulating valve, the stop valve and the balance regulating valve. And the recovered gas component balance system also comprises a gas supply flowmeter arranged on the gas supply branch and a balance flowmeter arranged on the balance branch and positioned between the tank group and the gas outlet end, wherein the gas supply flowmeter and the balance flowmeter are respectively connected with the controller and feed back the detected gas flow to the controller. The controller calculates how to mix the gas in the gas supply branch and the balance branch according to the gas components collected by the component analyzers, and generates corresponding control signals to the gas supply regulating valve, the stop valve and the balance regulating valve, so that automatic gas balance is realized.
The method specifically comprises the following steps: 1. each buffer tank is filled with recycled gas with any component; 2. when the gas inlet component analyzer at the online analysis point A analyzes that the content of a certain component in the recovered gas sent from the front end is lower than the gas component in the buffer tank and lower than a certain set value, the controller calculates the flow of the mixed gas required by the recovered gas stored in the buffer tank in the gas supply branch and the balance branch according to the component data, so as to generate a control signal to control and adjust the gas supply adjusting valve and the balance adjusting valve to adjust the flow, and the cut-off valve is matched with the switch, so that the content of the certain component in the recovered gas in the subsequent working section is stably output; 3. after a period of time, the gas in the buffer tank is changed into low-component recycled gas, when a certain set value is reached, the controller calculates the flow of the mixed gas required by the high-component recycled gas stored in the buffer tank in the gas supply branch and the balance branch according to the component data, generates a control signal to control and adjust the gas supply regulating valve and the balance regulating valve to regulate the flow, and the shut-off valve is matched with a switch, so that the recycled gas is directly output to a subsequent working section through the gas supply branch; 4. when the gas inlet component analyzer at the on-line analysis point A analyzes that the content of a certain component in the recovered gas sent from the front end is higher than that of a gas component in the buffer tank and higher than a certain set value, the controller calculates the flow of the mixed gas required by the low-component recovered gas stored in the buffer tank in the gas supply branch and the balance branch according to the component data, so that a control signal is generated to control and adjust the gas supply adjusting valve and the balance adjusting valve to adjust the flow, and the shut-off valve is matched with the switch to stably output the content of the certain component of the recovered gas in the subsequent working section; 5. after a period of time, the gas in the buffer tank is changed into high-component recycled gas, when a certain set value is reached, the controller generates control signals according to component data to control and regulate the gas supply regulating valve and the balance regulating valve to carry out flow regulation, the stop valve is matched with a switch, and the recycled gas is directly output to a subsequent working section through the gas supply balance branch; 6. and when the content of a certain component in the recovered gas sent from the front end is analyzed by the gas inlet component analyzer at the online analysis point A to be lower than the gas component in the buffer tank and lower than a certain set value, the steps are repeated.
The above embodiments are only for illustrating the technical concept and features of the present invention, and the purpose of the embodiments is to enable people skilled in the art to understand the contents of the present invention and to implement the present invention, which cannot limit the protection scope of the present invention. All equivalent changes and modifications made according to the spirit of the present invention should be covered by the protection scope of the present invention.
