Description

Description: TECHNICAL FIELD The present invention relates to an operation management apparatus for steam-using equipment, which enables the steam-using equipment to produce more products with higher quality while consuming less steam.

The steam produced by the boiler is sent to multiple steam-using devices and used as a heat source for heating, steam, heat retention, cooling, etc. to produce products.

Understanding the boiler evaporation (steam consumption) minimizes steam (fuel) consumption, maximizes production per unit of time, and produces higher quality products. It is important for improving quality and quality.

Conventional technology Conventionally, the evaporation amount of a boiler is obtained by excluding the boiler can water blow from the value of the water supply meter installed in the boiler, and the boiler efficiency is calculated from the fuel consumption used to operate the boiler. I was aware of it.

Also, a flow meter was installed to measure steam consumption. This will be described with reference to FIG.

The steam produced in the boiler 31 is sent to the steam-using devices 35 and 36 through the steam introducing pipes 33 and 34 branched from the steam main pipe 32.
Steam that has been used for heating or other work in the steam-using devices 35 and 36 becomes condensed water and is removed by the steam traps 37 and 38.

In the steam introducing pipes 33, 34, pressure reducing valves 39, 40 for reducing the pressure of the steam supplied to the steam using devices 35, 36 to a desired pressure and valves 41, 42 for controlling the supply of the steam are arranged.

A steam flow meter 43 is arranged in the steam main pipe 32, the amount of steam flowing through the steam main pipe 32 is measured, and the steam consumption amount is grasped.

Problems to be Solved by the Present Invention However, since it is not possible to know how much steam is consumed in each steam-using device, only by obtaining the evaporation amount (steam consumption amount) of the boiler, the steam consumption amount and the productivity can be improved. And the relation of quality is not understood.

The technical problem of the present invention is therefore to make it possible to manage the operation of steam-using equipment in relation to the steam consumption and productivity and quality of each steam-using equipment.

Means for Solving the Problems The technical means of the present invention taken to solve the above technical problem is to dispose a flow meter for measuring and displaying the steam consumption amount for each steam using device, and for each steam using device. Is equipped with means for measuring and displaying steam pressure, condensate temperature and product temperature, and means for calculating and displaying steam consumption for each steam using device and steam pressure and condensing water for each steam using device At the same time, the opening and closing of the control valve for adjusting the steam supplied to each steam using device is controlled by the above measured value for each steam using device.

Action The action of the above technical means is as follows.

Since a flow meter is attached to each steam-using device, the steam consumption of each steam-using device can be measured. Data can be collected separately for productivity per unit time. Moreover, since the temperature of the product is measured and the steam pressure and the condensate temperature are measured, it is possible to measure the calorie consumption of each steam-using device from the steam consumption amount, the steam pressure and the condensate temperature, and control the quality of the product Data is obtained.

Therefore, the operation of the steam-using device can be managed based on these data.

Effects of the invention Since steam consumption, steam pressure, condensate temperature, and product temperature are measured, these measured data can be automatically displayed at one time on a pen recorder, etc. You can grasp the status at a glance.

Moreover, since the opening and closing of the control valve is controlled according to the steam consumption, the steam pressure or the temperature of the product, the quality of the product can be automatically controlled.

Example An example showing a specific example of the above technical means will be described (see FIG. 1).

The steam produced in the boiler 1 is sent to the steam-using devices 5 and 6 through the steam introducing pipes 3 and 4 branched from the steam main pipe 2.
The steam that has been used for heating or the like in the steam-using devices 5 and 6 becomes condensed water and is automatically removed by the steam traps 7 and 8.

In the steam introducing pipes 3 and 4, pressure reducing valves 9 and 10 for reducing the pressure of the steam supplied to the steam using devices 5 and 6 to a desired pressure and control valves 11 and 12 for controlling the supply of the steam are arranged.

Condensate flowmeters 13 and 14 are placed between the steam-using devices 5 and 6 and the steam traps 7 and 8. The condensate flow meters 13 and 14 have condensate temperature sensors 15 and 16 for measuring the temperature of the condensate.

Pressure sensor 17 for measuring the steam pressure in the steam inlet pipes 3 and 4
・ Electrically connect the product temperature sensors 19 and 20 that measure the product temperatures of 18 and steam-using devices 5 and 6 to the condensate flowmeters 13 and 14. Further, the control valves 11 and 12 and the pen recorders 21 and 22 are electrically connected to the condensate flow meters 13 and 14.

The condensate flowmeters 13 and 14 measure the flow rate of the condensate to measure and display the amount of steam consumed by the steam-using devices 5 and 6, as well as the pressure value detected by the pressure sensors 17 and 18 and the product temperature sensor 19.・ Displays the temperature value detected by 20 and condensate temperature sensor 15 ・ 16. In addition, these measured values are
The voltage is output to 21 and 22.

Also, the condensate flow meters 13 and 14 calculate and display the calorific value from the steam consumption, steam pressure and condensate temperature, that is, the relationship between the steam consumption and the enthalpy of steam and the enthalpy of condensate, and at the same time, the steam consumption and steam Based on the pressure or the temperature of the product, the opening / closing control of the control valves 11 and 12 for adjusting the steam supplied to the steam using devices 5 and 6 is performed.
