Products used:
1. Temperature Monitoring Module (9211).
2. Pressure Monitoring Module (SCXI-1125).
3. Data Acquisition card (9172)
4. Analog input (9205).
5. Analog output (9263).
6. Digital input/output (9401)
7. LABVIEW 8.1 Express Software.
The Challenge:
The main objective of our project is mainly to meet the basic energy demands and
also to find an alternative solution for the solid waste management system.
The Solution:
Here we basically deal with the conversion of heat energy directly into electricity by the
thermo electric material. The concept in this conversion is that the domestic wastes are being
burnt with minimum effect on the environment. The process is monitored and controlled using
LABVIEW real time software.
Introduction:
The solid waste is collected from near by areas. After weighing, the waste goes to the
Waste-to-Energy plant. Here it is discharge into a huge bunker, and then incinerated over grates
round the clock. The heat generated is directly converted into electricity by the use of
thermoelectric material. The resultant electricity is supplied to local areas. The majority of
substance that does not burn is transformed into bottom ash that finds use in processes such as
road construction besides metal scrap recovery.
System Configuration:
In this system temperature monitoring module 9211 is interfaced with LABVIEW
software to detect and control the burning process. Pressure monitoring module is used to
maintain the pressure in the incinerator; if a pressure change takes place then the blower places
its part and brings it back to the required level. The level of raw material is checked periodically
with the help level indicator sensor.
System implementation:
The system can be divided into two modules
1. Monitoring module.
2. Controlling module.
The above two can be controlled by LABVIEW software.
1. Monitoring Module:
In this module we are monitoring three parameters – temperature, pressure, level of
raw material.
2. Controlling Module:
In order to maintain an uninterrupted operation of the unit the above parameters
are controlled in this module.
Conclusion:
Hence using this system we can rectify the ever lasting problem of solid waste
management and shortage of energy. This system is highly efficient productive and reduces the
pollution of the environment to the greatest extent.
