Detailed Description
In order to make the above objects, control system and advantages of the present invention more apparent, the present invention will be further described in detail with reference to the following embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.
Referring to fig. 1, a waste heat bath device dedicated for steam pipe network of coke-oven plant includes:
a steam pipe network 1 of a coking plant;
a water tank for supplying hot water to the bathing equipment;
a heat exchanger for isolating harmful gas source and exchanging heat; in order to isolate harmful gases, the heat exchanger is a dividing wall type heat exchanger; wherein:
the steam pipe network 1 of the coking plant is connected with a first medium circulating pipe port of the heat exchanger; the water tank is connected with a second medium circulating pipe port of the heat exchanger through a circulating water pipe; a manual valve 2 and an electric valve 3 are arranged on the steam pipe network 1 of the coking plant; a circulating pump is arranged on the circulating water pipe; the circulating pump is connected with a time control switch, and the working time and the shutdown time of the circulating pump can be set through the time switch, for example, the circulating pump is started from 4 pm to six pm and is stopped at other times; a temperature sensor and a water level sensor are arranged in the water tank; and the water tank is connected with a water replenishing pipeline.
The steam pipe network 1 of the coking plant comprises an air inlet section and an air outlet section; the manual valve 2 and the electric valve 3 are installed at the air intake section along the steam flow direction.
The temperature sensor comprises a thermal resistor 6 and a digital display controller, and the thermal resistor is connected with the digital display controller. The resistance value of the thermal resistor and the temperature have a one-to-one linear relation, so that the numerical value of the water temperature in the water tank can be obtained by detecting the resistance value of the thermal resistor; the digital display controller is respectively connected with the electric valve 3 and the circulating pump through an intermediate relay. On one hand, the digital display controller; receiving a signal of the thermal resistor, and converting the signal of the thermal resistor into a water temperature signal for displaying; on the other hand, the water temperature signal is compared with the threshold value signal, when the water temperature is lower than the threshold value, the digital display controller sends a closing instruction to the intermediate relay, then the electric valve 3 is opened, and steam in the pipe network enters the water tank to be heated; otherwise, the intermediate relay is turned off.
The model of the digital display controller is XMT-9000 (Meiri Meter Co., ltd., kunshan).
The water level sensor is a float, the float valve is arranged at the end part of the cold water pipeline 4, and the float valve 5 is arranged on the cold water pipeline 4;
this application adopts the indirect water to heat in the water tank of heat exchanger, and the water after the heating can be used to the bathing, owing to kept apart toxic gas, consequently can guarantee safety. Because the steam in the steam pipe network 1 of coke-oven plant and the pressure of water have undulant during, when manual regulation can hardly have the regulation untimely, the temperature can appear overheated or low excessively, in order to mend the invariant of temperature in the water tank, this application is through constitution regularly constant temperature automatic control system such as application motorised valve, circulating pump, temperature display table, time switch, auxiliary relay, and the operation is respond well, and the water tank liquid level passes through float valve control, guarantees the water tank water level. If the water temperature of the water tank is lower than the set temperature, the electric valve of the heat exchanger automatically opens steam to start heating, and if the water temperature of the water tank reaches the set temperature, the electric valve of the heat exchanger automatically closes the steam to stop heating, and warm water circulates; the temperature of the water tank is ensured to be stable. When the steam valve is not in the time range set by the time control switch, the circulating pump automatically stops, the intermediate relay of the electric valve loses power, and meanwhile, the normally closed point of the intermediate relay of the electric valve is connected with the steam electric valve to be closed, so that the steam valve is always in the closed position. Energy is saved and waste is avoided. If the post needs to use water outside the specified time period of the factory due to reasons, the time switch is not in the set time range, the circulating pump can be started manually, and automatic temperature adjustment can still be realized.
The above description is only exemplary of the present invention and should not be construed as limiting the present invention, and any modifications, equivalents and improvements made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
