The device constituted by preceding method, including the inlet manifold being connected with gas burner and house steward user being connected with user
And clean gas house steward；It is clean provided with one group of washer and dust-precipitator being connected in series between inlet manifold and clean gas house steward
Provided with one group of gas exhaust machine between gas house steward and house steward user；Recirculation pipe is provided between house steward user and inlet manifold
Road, recirculation conduit is provided with pressure-reducing valve.
In aforementioned means, one group of gas exhaust machine is the gas exhaust machine of the most frequently used same displacement.
In aforementioned means, the pressure-reducing valve is made up of the valve of three series connection；Recirculation conduit after pressure-reducing valve and one
Group recycling branch pipe connection, one group of recycling branch pipe is connected with one group of washer entrance respectively.
In aforementioned means, the junction at the gas exhaust machine two ends, pressure-reducing valve front end and recycling branch pipe and washer
It is equipped with valve.
Compared with prior art, method of the present invention by setting up recirculation conduit between house steward user and inlet manifold
Unnecessary coal gas is returned to inlet manifold or washer entrance, to reduce user's manifold pressure, it is ensured that user terminal gas pressure
Be maintained in safe range.So gas exhaust machine group can also use the gas exhaust machine of same size, it is to avoid different rule
Frequent start-stop between the gas exhaust machine of lattice, alleviates the workload of production run personnel, also causes the specification number of equipment and spare part
Amount is greatly reduced, and can constitute gas exhaust machine group using the gas exhaust machine of the most frequently used specification, production cost greatly reduces,
Be conducive to production management.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention；
Fig. 2 is the structural representation of prior art.
Mark in accompanying drawing for：1- gas burners, 2- inlet manifold, 3- user, 4- user house steward, the clean gas house stewards of 5-, 6-
Washer, 7- dust-precipitators, 8- gas exhaust machines, 9- recirculation conduits, 10- pressure-reducing valves, 11- recycling branch pipe, 12- valves.
Embodiment
The present invention is described in further detail below in conjunction with the accompanying drawings, but not as any limitation of the invention.
Ensure the method for gas exhaust machine underload stable operation, as shown in Figure 1.This method is the most frequently used using one group
The gas exhaust machine of same displacement supplies for user；To improve the interchangeability of equipment and spare part, the specification quantity of equipment and spare part is reduced；
Reduce the cost of equipment and spare part.When minimum coal gas dischargeable capacity in less than one group gas exhaust machine of coal gas load of coal gas user
When, unnecessary coal gas is returned to by inlet manifold or washer entrance by the recirculation conduit that is connected on house steward user, then
Circulating line is provided with pressure-reducing valve；Pressure in house steward user is adjusted by pressure-reducing valve, it is ensured that gas exhaust machine can be transported normally
OK.Pressure-reducing valve is made up of the valve of three series connection.The gas exhaust machine two ends, pressure-reducing valve front end and recirculation conduit are with washing
The junction for washing device is equipped with valve；Gas exhaust machine, pressure-reducing valve and washer are controlled with facilitating.
The device constituted by preceding method, including the inlet manifold 2 being connected with gas burner 1 and the user being connected with user 3
House steward 4 and clean gas house steward 5；Provided with one group of washer 6 being connected in series and receipts between inlet manifold 2 and clean gas house steward 5
Dirt device 7, the gas exhaust machine 8 provided with one group of the most frequently used same displacement between clean gas house steward 5 and house steward user 4；In user
Recirculation conduit 9 is provided between house steward 4 and inlet manifold 2, recirculation conduit 9 is provided with pressure-reducing valve 10, and pressure-reducing valve 10 is by three
The valve of series connection is constituted；Recirculation conduit 9 after pressure-reducing valve 10 is connected with one group of recycling branch pipe 11, one group of recycling branch pipe
11 are connected with one group of entrance of washer 6 respectively.The two ends of gas exhaust machine 8, the front end of pressure-reducing valve 10 and recycling branch pipe 11 with
The junction of washer 6 is equipped with valve 12.
Fig. 2 is the structural representation of prior art.
From Figure 2 it can be seen that prior art is not provided with recirculation conduit 9, one group of coal gas row used in the prior art in addition
Sending machine is made up of the different gas exhaust machine of dispatch amount, and the operation quantity of gas exhaust machine is carried out according to as user with gas load
Regulation, when user is larger with gas load, opens several gas exhaust machine supply more, when user is smaller with gas load, just few use
Several gas exhaust machine supply, but user is very small with gas load sometimes, only opens a gas exhaust machine and is supplied for user, but uses
The gas pressure at family or exceeded, it is impossible to ensure that user uses the safety of coal gas.In order to ensure the stabilization of user terminal gas pressure
Property, some less gas exhaust machines of dispatch amount can only be set in one group of gas exhaust machine, one group of coal gas is thus caused
There is the gas exhaust machine of plurality of specifications in dispatch machine, if gas consumption frequently changes, between the gas exhaust machine of different size
Frequent start-stop, can roll up the workload of production run personnel therewith, due to the gas exhaust machine using different size, also make
Spare Parts increase is obtained, these are all unfavorable for production management.
The present invention is returned unnecessary coal gas by setting up the method for recirculation conduit between house steward user and inlet manifold
Inlet manifold or washer entrance are delivered to, to reduce user's manifold pressure, it is ensured that user terminal gas pressure is maintained at safe model
In enclosing.So gas exhaust machine group can also use the gas exhaust machine of same size, it is to avoid the gas exhaust machine of different size
Between frequent start-stop, alleviate the workload of production run personnel, also cause equipment and spare part specification quantity greatly reduce, can adopt
Gas exhaust machine group is constituted with the gas exhaust machine of the most frequently used specification, production cost greatly reduces, is conducive to production management.
