Application of germanjet magnetostrictive displacement sensor in waste incineration equipment

Release date: June 19, 2019 Hits: 53

With the phenomenon of "garbage besieged city" becoming more and more serious, waste incineration power generation projects have been launched in various cities. As a typical project of solid waste treatment and waste heat utilization, waste incineration power generation belongs to the energy conservation and emission reduction project explicitly supported by national policies.

According to different incineration principles, incinerators in the world are mainly divided into grate furnace incineration, fluidized bed incineration and pyrolysis. This case introduces germanjet Displacement sensor The application of the product in the grate furnace of waste incineration. Germanjet Displacement sensor Through the high accelerated life test (HALT), it has good product performance, especially in high temperature resistant occasions, it can also ensure stable signal feedback, so as to ensure the continuous and efficient operation of your equipment system.

technological process

Garbage incineration is to transport the municipal waste to the garbage pool of the incineration plant, which is lifted into the hopper, and then slowly enters into the furnace hall. After three stages of drying, burning and burning out, under the combustion supporting condition of a large amount of oxygen (the excess air coefficient is equal to 1.8), the garbage is fully burned in the grate with different methods, and the burnt slag is transported to the slag pool for cooling before being transported to the outside of the plant for landfill. A large number of high-temperature flue gas (850-900 ℃) generated after waste combustion enters the waste heat boiler for heat exchange, and the superheated steam enters the steam turbine generator set for power generation.

Grate incinerator

Inclined reciprocating multistage grate composed of different grate components (or units).

Each standard grate unit has three types of grate: sliding grate, turning grate and fixed grate. The incinerator is composed of four standard grate units and one long unburned grate unit. The grate is driven by hydraulic device. Each furnace is equipped with a set of hydraulic device and can be controlled separately.

Automatic combustion control of incinerator

When the operator inputs the expected load (steam production or waste treatment capacity) into the system, the system will immediately respond by adjusting the action of feeding grate and combustion grate, and adjusting the air volume of primary air and secondary air.

The quantitative feeding of the feeding grate, the sliding speed of the sliding grate and the turning times of the turning grate are continuously regulated by the system. The output of the controller ultimately makes the operation of the whole waste incineration plant in a stable mode, so there is little need for operator intervention.

Germanjet magnetostrictive displacement sensor It is mainly used for real-time position signal feedback of sliding grate and turnover grate of waste incinerator.

The sliding grate blade pushes the garbage layer to move forward slowly and continuously on the grate. The movement of grate plate determines the thickness, residence time, treatment capacity and combustion quality of refuse layer. By using the displacement sensor to monitor the moving displacement of sliding grate on-line, the quantity of refuse delivered to the next grate can be continuously monitored, so as to improve the quality of refuse combustion.

Translational motion

Turning the grate to loosen the garbage and inflate it to the garbage is necessary to dry and ignite the garbage, promote combustion and achieve complete combustion. Through the continuous displacement feedback of the displacement sensor, the turning action size of the turnover grate can be adjusted in real time according to the size of the waste feeding amount, so as to improve the waste incineration efficiency.

The multi-stage incinerator grate is the only centralized incineration system which adopts garbage transportation and mixing / blowing independently. The system is easy to adjust according to the change of waste composition, especially suitable for domestic waste treatment with low calorific value and high moisture content. In addition to standard sensors, baruff can also provide customized products and services for customers' on-site high-temperature occasions.
