Description
Technical Field
The invention relates to a steam heating control system for a textile setting machine, in particular to a steam heating intelligent energy-saving control system for the setting machine.
Background
In the known printing and dyeing industry, the heating system of the setting machine generally adopts steam heating and is conveyed by a uniform steam pipeline. The setting machine is provided with a plurality of setting ovens which are arranged in sequence. The steam pipeline conveys high-temperature steam, the high-temperature steam enters each section of drying oven and exchanges heat with air in the drying oven through a heat exchanger of the drying oven, and therefore the temperature of the air in the drying oven is increased to meet the setting work requirement.
In a traditional steam heating control system, the proportion of the time for opening and closing an electric valve on a steam pipeline is controlled through a temperature controller, so that the conveying and the shutdown of high-temperature steam are influenced, and the constant temperature state of each section of drying oven is controlled through PID. This traditional control mode, high temperature steam circulation is undulant great, and operating condition is unstable, influences the constant temperature performance of oven.
In addition, high temperature steam is through the heat exchange cooling, and the part becomes the comdenstion water, and traditional equipment passes through trap separation steam, gets into the collector pipe behind the comdenstion water derivation oven, flows back to storage devices such as flash tank or hot-water drum to cyclic utilization. The high-temperature steam passes through the heat exchanger to form condensed water and the high-temperature steam.
Because the traditional trap is of a mechanical structure and is controlled to open and close by a floating body, the trap is sensitive to pressure, and a certain passing aperture exists in the trap body, so that the phenomenon of gas leakage exists. When the high-temperature steam is switched on or off, the pressure change at the input end of the drain valve is greatly fluctuated, the sealing performance of the drain valve on gas is influenced, and when condensed water is drained, a large amount of high-temperature steam overflows when the state of the electric valve is switched and cannot be effectively utilized.
In addition, the conventional multi-section oven, the first and final ovens, as the beginning and end of the sizing process, have lower operating temperatures than other ovens. The traditional heating system does not optimize the two sections of drying ovens, thereby wasting heat energy and water resources and being not beneficial to energy conservation and emission reduction.
Therefore, the traditional steam heating system of the setting machine has the defects of unstable working state, overflow of high-temperature steam, poor overall energy-saving effect, waste of heat energy and water resources and the like.

According to the technical scheme, except for the first box and the tail box, the water inlet end of the other middle boxes is connected with the main steam pipeline through a manual steam inlet valve, a filter valve and an electric regulating valve.

Detailed Description
The following description of the embodiments of the present invention will be made with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.
As shown in fig. 1, the adopted oven system of the setting machine has 10 oven body bodies from front to back, the first oven is a first oven, the last oven is a tail oven, the oven provides high-temperature steam through a main steam pipeline, the high-temperature steam enters each section of oven, and the heat exchanger in the oven exchanges heat with air in the oven to raise the internal temperature of the oven to the working temperature. The high-temperature steam is cooled after passing through the heat exchanger, part of the high-temperature steam forms condensate water, the condensate water of each oven body is collected together through a water collecting pipe and finally conveyed to a collecting device such as a flash tank or a hot water bucket, and the water is recycled.
The other intermediate tanks except the first tank and the tail tank, namely the second tank to the ninth tank, in the technical scheme of the invention all adopt the same pipeline structure for conveying high-temperature steam and discharging condensed water. Taking the second tank as an example, high-temperature steam is provided by a main steam pipeline, is communicated with the water inlet end of the second tank sequentially through a manual steam inlet valve 1, a filter valve 2 and an electric regulating valve 3, flows through a heat exchanger in the second tank, and is connected to a water collecting pipe sequentially through a Y-shaped drain valve 4 and a manual water outlet valve 5 by the water outlet end of the second tank.
In the pipeline structure, a manual steam inlet valve 1 and a manual water outlet valve 2 are mainly used for adjusting the maximum traffic volume and are manually controlled during maintenance; the function of the filter valve 2 is to filter out impurities contained in the high-temperature steam, and all the filter valves are designed conventionally. Compared with the traditional design, the technical scheme of the invention is that the prior electric valve which can only be opened and closed is cancelled in the steam inlet pipeline, the electric regulating valve 3 is adopted and is driven by the motor, and the opening amount of the valve can be controlled; in the water outlet pipeline, a Y-shaped drain valve 4 in a switch state driven by high-pressure gas is adopted, so that the overflow phenomenon of high-temperature steam can be effectively inhibited.
Because the electric control valve and the Y-shaped drain valve can not be controlled by a simple PID control circuit, the technical scheme of the invention adopts a PLC programmable logic control circuit for intelligent control, and related circuits are explained later.
Aiming at the characteristic that the working temperature of the first box and the tail box is lower, in order to save the steam consumption, the technical scheme of the invention adopts a method of taking the condensate water generated by the middle box as a heat exchange heat source of the first box and the tail box. The specific method is that an electric drain valve I7 is arranged at the front end of the water collecting pipe and before the water outlet ends of all the middle tanks are connected to the end point of the water collecting pipe, and a first tank water inlet pipe 6 is connected with the water collecting pipe and the first tank water inlet end behind the electric drain valve I7; the water outlet end of the first tank is connected to the water collecting pipe through a first tank water outlet pipe 13, the connecting position is located in front of the electric drain valve I7, and a first tank probe 8 is arranged at the connecting position of the water outlet end of the first tank and the first tank water outlet pipe.
The middle part of the water collecting pipe is provided with an electric drain valve II 9 which is positioned behind the end point of the water collecting pipe connected to the water outlet end of the front half of the oven; in this embodiment, the access point is located between the fifth box access endpoint and the sixth box access endpoint.
The water inlet end of the tail tank is connected to the water collecting pipe through a tail tank water inlet pipe 10, and the connecting position is the tail end of the water collecting pipe; the water outlet end of the tail tank is connected to the water collecting pipe through a tail tank water outlet pipe 14, the connecting position is located in front of the electric drain valve II 9, a check valve 11 is installed in the middle of the tail tank water outlet end, and a first tank probe 12 is arranged at the connecting position of the tail tank water outlet end and the tail tank water outlet pipe.
The first electric drain valve 7 and the second electric drain valve 9 are in a closed state in normal work, therefore, during normal work, the condensate water generated from the sixth box to the ninth box is blocked by the second electric drain valve 9 and flows to the rear end of the water collecting pipe, and enters the tail box through the tail box water inlet pipe 10, after heat exchange, the condensate water flows back to the front of the second electric drain valve 9 and is converged with the condensate water generated from the second box to the fifth box, flows forwards until being blocked by the first electric drain valve 7, and enters the first box from the first box water inlet pipe 6, after heat exchange is completed, and before the first box water outlet pipe 13 leads to the first electric drain valve 7, the condensate water enters the storage device. The flow in the pipe is shown by the arrows on the lines.
The technical scheme of the invention better utilizes the waste heat of the condensed water, can save the consumption of hot steam by 10 to 15 percent compared with the traditional design, and also saves corresponding water resources.
The condensed water is the condensed water formed by heat exchange of high-temperature steam at about 250 ℃ originally, and the temperature is above 90 ℃, which is enough to meet the requirement of the working temperature required by the first tank and the tail tank.
As shown in fig. 2, when the electric drain valve i 7 and the electric drain valve ii 9 are opened, the water collecting pipe has no circulation obstacle, the condensed water directly flows into the storage device without passing through the first box and the tail box, and the state is mainly used for quickly emptying the cold water accumulated in the oven when the electric drain valve i is started, so that the waste heat energy caused by the reaction of the high-temperature steam and the cold water can be avoided, and the phenomenon that the heat exchanger vibrates to influence the service life of the machine due to the local boiling after the high-temperature steam is contacted with the cold water is also avoided.
As shown in fig. 3, the control circuit of the technical solution of the present invention employs a PLC programming control system, and installs temperature probes in other intermediate boxes except the head box and the tail box to provide real-time temperature parameters; the PLC programming control system independently controls the opening degree of the electric regulating valve connected with each box and the opening and closing of the Y-shaped drain valve through the acquired data of each temperature probe.
In summary, the invention provides an intelligent energy-saving control system for steam heating of a setting machine, which has the advantages of stable working state, no overflow of high-temperature steam, no need of additionally providing steam for part of a box body, energy saving, water saving and the like, thereby solving various problems in the prior art. The above description is only a preferred embodiment of the present invention, and in the actual deployment process of the present invention, it is not possible to operate completely according to the above embodiments due to different requirements of the production process, so the embodiments of the present invention should not be construed as limiting the present invention. It should be noted that, for those skilled in the art, without departing from the technical principle of the present invention, several improvements and modifications can be made, and these improvements and modifications should be considered to be within the effective protection scope of the present invention.
