Description

  The present invention relates to a pumping device that pumps a solid-liquid mixture or a fluid, a pumping method thereof, and an incinerator that incinerates the solid-liquid mixture or fluid. In particular, the present invention relates to a pumping device suitable for pumping a solid-liquid mixture or fluid whose properties change, and a pumping method thereof, and an incinerator suitable for incinerating a solid-liquid mixture or fluid whose properties change.

Piston cylinder type positive displacement pumps are used to transport solid-liquid mixtures or fluids such as industrial waste. Volumetric pumps are particularly good at pumping highly resistant solid-liquid mixtures or fluids.
For example, a positive displacement pump in the form of a piston cylinder is used in an industrial waste treatment facility.

Hereinafter, an industrial waste treatment facility and a pumping device employing a piston cylinder type positive displacement pump which can be used there will be described.
When industrial waste is a hazardous material such as a solvent, the drum can containing the hazardous material such as a solvent is safely crushed in a nitrogen atmosphere, and the crushed material is kneaded in a mixer to uniformize the properties, and then pumped. It is transported to the incinerator by the device and burned in the combustion furnace.
Since the fixed amount is supplied by the piston pump, the calorific value of the processed material is leveled, and the fuel furnace can be stably operated continuously.

Conventionally, a piston pump is driven by hydraulic pressure, and continuously reciprocates a piston with a predetermined stroke.
Since the properties of the solid-liquid mixture or fluid change from time to time, the resistance force when pumping with a piston pump also changes from time to time.
Therefore, when the piston is operated with a constant force, the time required for the piston to move one stroke varies.
As a result, the amount of the solid-liquid mixture or fluid supplied to the combustion furnace fluctuates, causing a phenomenon in which the furnace temperature fluctuates around the average temperature.
The allowable maximum temperature of the furnace temperature of the combustion furnace is determined to a predetermined temperature (for example, 1200 ° C.) depending on the heat resistance temperature of the material constituting the furnace wall.
Further, the allowable minimum temperature of the in-furnace temperature of the combustion furnace is determined to a predetermined temperature (for example, 950 ° C.) depending on the in-furnace temperature to be maintained in operation.

The piston 72 is a member that is fitted in the hollow space so that the stroke along the longitudinal direction of the cylinder can reciprocate.
For example, the hollow space H is a columnar space, and the piston 72 has a cylindrical shape that fits into the hollow space H.
Here, one stroke of the piston 72 is the distance S. When the front part of the piston 72 moves from the rear end E1 of the stroke to the front end E2, the volume of the space surrounded by the piston 72 and the cylinder 71 changes from the maximum to the minimum. When the front portion of the piston 72 moves from the front end E2 to the rear end E1 of the stroke, the volume of the space surrounded by the piston 72 and the cylinder 71 changes from the minimum to the maximum.

Therefore, the process of temporarily stopping the piston after moving it by N strokes is repeated at every predetermined timing.
The predetermined timing is determined by an operation request for the pumping device or the combustion device.
For example, the predetermined timing is a certain time. In this way, accurate quantitative supply is possible, so when the amount of heat per unit volume is stable, the amount of heat supplied to the incinerator per unit time is stable, and the furnace temperature at the inlet is stabilized. .
Further, for example, the predetermined timing is a timing for maintaining the temperature in the furnace at the charging port of the incinerator at a predetermined value. In this way, the in-furnace temperature can be maintained at a predetermined value by controlling the amount of the solid-liquid mixture or fluid fed to the incinerator.
Further, for example, the predetermined timing is the timing at which the amount of heat of the solid-liquid mixture or fluid that is pumped per unit time becomes constant. In this way, the in-furnace temperature can be maintained at a predetermined value while keeping the amount of heat of the solid-liquid mixture or fluid fed to the incinerator constant.
