Abstract

PURPOSE:To reduce the outflow rate of steam during an exhausting operation, by controlling a valve actuator by means of a controller having a reference value setter in response to a signal from a temperature sensor. CONSTITUTION:An exhaust pipe 9 is attached above a steam space 2 in confunction with an exhaust valve 11. The exhaust valve 11 is provided with a valve actuator 10. An electric temperature sensor 14 is provided above the steam space 2. A reference numeral 15 indicates a pressure sensor. Two sensors 14, 15 are connected via a signal line with a controller 12 having a reference value setter 13. That is, the valve actuator 10 is controlled to open and close the exhaust valve 11 respectively in response to the rise and fall of temperature inside the steam space 2 relative to a reference temperature level. By constructing the exhaust device as described above, the valve is opened and closed at a temperature close to a saturation temperature, that is, when an air mixing ratio is small, and thereby reducing the outflow rate of steam.

(Objective) The present invention relates to a device for exhausting air accumulated in a steam space of a steam heating device. When the steam heating device is started by sending steam, a large amount of air that was present in the inlet piping system flows into the steam heating device. Also, during operation, when steam is generated, water (h+l) and air (tflif) flow in together with the steam. If air accumulates in the steam space of a steam heating device, the humidity of the steam space will drop and the IJII thermal efficiency will decrease.
Is it necessary to evacuate the air? Therefore, conventionally, as shown in Figure 2, the steam space 5
In the exhaust passage 60 at the top of the steam space 50, install the steam valve 51 that operates automatically. I was trying to exhaust it. The steam passes through the passage 54 and is reduced to 11-1 by the sludge reduction valve 59 and supplied to the steam heating equipment 53, and the condensate generated there is discharged through the passage 55 by the steam 1-lap 5G. The side slope enters heating equipment 5/3 through passage 57 and is heated, and the product exits through passage 58 h+. However, there was a problem in that a large amount of steam was allowed to escape at the end of the exhaust. This is because the conventional exhaust system 4.7 is operated by a bimetal or a heat-sensitive gas flow tube. In other words, since the response of these thermosensitive members is slow to temperature changes, the temperature of the steam space will be much higher when the valve is opened than when the valve is opened. The valve must be set to open at a low temperature, which means that the air mixing ratio is 3.
This is because the valve opens when the ratio is 0 to 50%. In particular, in the case of base valves, the opening/closing valve temperature is determined by the sealed fluid, and it is difficult to change the set temperature, so a large amount of steam flows out during exhaust. Therefore, if the air mixing ratio in the steam space can be maintained at a low value, the above problem is solved. The technical problem of the present invention is to make the opening/closing valve operation of the illumination device respond sensitively to changes in the temperature of the steam space. The idea is to open and close the valves at similar temperatures. (Structure) The technical means of the present invention aimed at solving the above problems is as follows e). (a) An electric sensor is installed in the steam heating equipment to detect moisture in the steam space, and (b) an actuator is used to drive the passage to discharge air accumulated in the steam heating equipment. Place the exhaust valve (c)
Equipped with a reference value setting device and a converter roller of 2m v'1
.. The valve actuator is controlled according to the signal from the sensor to open the exhaust valve when the air space is below the set temperature. The above means works as follows. However, an electric temperature sensor is used to measure the temperature of the steam space. α change′J52
The signal is sent to the controllers 1 to 1. Controller 1~Roller receives the signal from Hinley once, t,,t
Compared with i% jiQ, if the signal value of sensor I) + is smaller than the reference value, the actuator opens the valve.

Saturation pressure on the element〕j
By storing the corresponding data of the saturated temperature and the saturated temperature, it is possible to automatically set a standard (1f4) lower than the saturated temperature according to the pressure of the steam space. (Specific Effects) The present invention has the following specific effects. In a mixture of steam and air, when the mixing ratio of air is small, the air is smaller than the steam, so it separates and collects at the top.In the present invention, the temperature change in the steam space is 1; 2 It reacts quickly and opens/closes the valve when the temperature is close to the saturation temperature, that is, when the air mixture ratio is small, so the fluid with a high proportion of air in the upper part of the steam space can be discharged, and the steam In addition, since the steam space is maintained at a low air mixing ratio, the temperature drop is small.The efficiency of the heating unit depends on the temperature difference between the steam space and the material. Heating efficiency is improved. (Example) A specific example of the present invention will be explained below (see Figure 1). The steam heating device 1 is a hollow container, and a material inlet pipe is provided on the side wall. 7 and a product outlet pipe 8 are connected to the heating pipe 17. Both pipes 7, 8 are placed in the steam space 2 in the vessel of the heating device 1 and connected to the heating pipe 17. Steam supply A pipe 3 is connected to the upper part of the steam space 2. A pressure reducing valve 4 is attached to the supply pipe 3. Valves are attached to bypass valves parallel to the pressure reducing valve 4, both before and after the pressure reducing valve 4. At the bottom of steam space 2, there are 5 condensate J] I exits I11
It is. Take the steam trap 6 for the discharge answer 5 (=
There are valves in front and behind this, and in the bypass pipe parallel to this. An exhaust valve 11 is disposed in communication with the upper part of the steam space 2 to open a JJI whistle. The exhaust valve 11 is equipped with a valve actuator 1 that drives the valve using an external force such as electricity or flow pressure.
Take 0 and subtract 1. An electrical temperature control 14 is installed in the upper part of the steam space 2. Reference number 15 indicates a pressure hinge. Both switches 171, 15 are connected to the controller 12 by signal lines. 2) The controller 1 to the roller 12 are connected to the reference value setter 13. The controller 1 to the roller 12 are connected to the signal from the temperature sensor 14.
A comparator which compares it with the f4% value and outputs an indication signal to the valve actuator is set. That is, the temperature of steam space 2 is lower than the standard humidity (JJI gas valve 1)
Control the valve actuator so that it opens, or closes if it rises. The reference value setter 13 may be one that adjusts the electrical characteristics of circuit elements such as the base wall resistance of the comparator. The rollers 12 to 1 are provided with means for adjusting the i ilj value according to the input from the nica center 9) 15. This can be effectively carried out by using a microcomputer in the converter roller 12 and by using a semiconductor (this memory element) that stores the corresponding values of saturation pressure and saturation temperature as the reference value setting device 13. In this case, , the reference value is set dynamically to white with 1 nica to r core.
