Description
Technical field
The utility model relates to a kind of denitration CEMS flow measurement signal transmitting device connection structures, belong to denitration CEMS stream
Measurement technique field.
Background technique
In recent years, with the universalness of industry, the improvement of people's living standards, increasingly severe, the work of global atmosphere pollution
Industry civilization and urban development are also discharged into the exhaust gas and waste that billions of tons are counted greatly while creating great wealth for the mankind
Among gas, atmospheric thermodynamics for the survival of mankind is but at aerial garbage warehouse and poison gas library, pernicious gas and pollution in an atmosphere
When object reaches a certain concentration, huge disaster will be brought to the mankind and environment, not only can harmful to human health, also endanger animal
Existence and development, furthermore atmosphere pollution will cause the corrosion of object and the variation of global climate, and wherein industrial air pollution is most
It is serious.
Utility model content
In order to solve the above technical problems, the utility model provides a kind of denitration CEMS flow measurement signal transmitting device company
Binding structure, denitration CEMS flow measurement signal transmitting device connection structure can reduce the workload of service personnel, improve people
Member job security, flow measurement accuracy and reliability.
The utility model is achieved by the following technical programs.
A kind of denitration CEMS flow measurement signal transmitting device connection structure provided by the utility model, including flow measurement
Device, transmitter, distributor, DSC system and denitration CEMS, the flow measurement device, transmitter, distributor are sequentially connected,
The output of distributor two-wire, is separately connected DSC system and denitration CEMS, DSC system is connect with denitration CEMS.
The flow measurement device, transmitter, distributor determine the number of setting according to the size of unit.
The control logic circuit of addition and division is equipped in the DSC system.
The model NPPD-CM111D of the distributor.
The distributor is the active 4~20m Α signal output of two-way.
The transmitter is two-wire system transformer.
The utility model has the beneficial effects that: eliminating live flow velocity computing device, directly transducer signal is distributed
It is sent into DCS and CEMS system afterwards, improves the reliability of Flow Measuring System, the job security of maintenance personnel, and allows upload
The validity of environment protection digital is also promoted therewith, reduces the workload of maintenance personnel and the maintenance cost of equipment.
Detailed description of the invention
Fig. 1 is the modular structure schematic diagram of the utility model.
Specific embodiment
Be described further below the technical solution of the utility model, but claimed range be not limited to it is described.
As shown in Figure 1, a kind of denitration CEMS flow measurement signal transmitting device connection structure, including flow measurement device,
Transmitter, distributor, DSC system and denitration CEMS, the flow measurement device, transmitter, distributor are sequentially connected, distributor
Two-wire output, is separately connected DSC system and denitration CEMS, DSC system is connect with denitration CEMS.
The flow measurement device, transmitter, distributor determine the number of setting according to the size of unit, such as: 600,000 machines
Group is there are two flue, and each flue is respectively arranged 4 flow measurement devices, transmitter, distributors, and there are two cigarettes for 300,000 units
Road, each flue only need to arrange 2 flow measurement devices, transmitter, distributors respectively.
The control logic circuit of addition and division is equipped in the DSC system, for judging and calculating flow velocity；
Further, the control logic circuit of the addition and division, using routine techniques, such as application No. is
Divider logic circuit disclosed in 2011103943780 Chinese patent and the method for realizing divider logic circuit, such as apply
Number for 2011204940041 Chinese patent disclosed in divider logic circuit, for another example application No. is in 2013106425049
A kind of SMPS and its control circuit and control method of state's patent disclosure, for another example network address are as follows: https: //blog.csdn.net/
The open source information of wzp1421166369/article/details/78389257 (simple add circuit principle).
The signal of the model NPPD-CM111D of the distributor, output can be directly accessed the AI fastener of DCS system,
The drawbacks of signal distributor belongs to the universal product, and buying is convenient, and flow relocity calculation device can effectively be avoided to deal exclusively, no
The convenience for increasing only system maintenance, also saves maintenance cost.
The distributor is two-way active 4~20m Α signal output, fast response time, low in energy consumption.
The transmitter is two-wire system transformer, and only two external cablings, are both power supply line and signal wire, installation side
Just, transmitting range is long.
The utility model is sent into four pick-ups during the work time, the data of four flow measurement devices in flue
Device, transmitter send data to distributor, and distributor splits data into two-way, while being sent to denitration CEMS and DCS system, pass through
AI fastener in DCS system is converted into digital signal, then respectively 1~flow of flow 4, while judging input with denitration CEMS
Whether data are normal, are normally transmitted to DCS system and screen to the digital signal of DCS system, utilize addition and division control
Logic circuit averaged processed, this average value are exactly mean flow rate, and mean flow rate is being sent to the flowmeter that producer provides
It calculates formula and calculates outflow, show in DCS system picture or denitration CEMS monitoring system picture, mentioned using this algorithm later
The high reliability of flue gas flow signal measurement.
