The utility model also comprises a controller, wherein signals of the device for detecting temperature is transported to the input end of the controller and the signal output end of the controller is connected with the signal input end of the regulating valve. The utility model is mainly applied to the recovery of various dead steam and flash evaporation secondary steam.
Description
Technical field
The utility model relates to a kind of water-jetting type exhaust steam recoverer.
Background technique
Exhaust steam typically refers to the water vapor of doing merit, because its grade (temperature, pressure) is lower, no value is normally gone out by airborne release concerning some units, as some chemical plant, rubber plant etc.But the common heat enthalpy value of this exhaust steam is higher, causes certain thermal waste to airborne release, and atmosphere has been formed thermo-pollution.
The someone has invented the water-jetting type exhaust steam recoverer for this reason, promptly utilizing the water-jetting type exhaust steam to reclaim pump reclaims exhaust steam, the water-jetting type exhaust steam is reclaimed pump and is comprised Laval nozzle, mix pressing chamber, venturi, expansion supercharging section, its working principle is: utilize water pump low temperature water (demineralized water or softened water) to be pressed into the water intake of Laval nozzle, form the region of no pressure at nozzle place ultra high speed jet, exhaust steam is sucked the mixing pressing chamber from the opening that mixes pressing chamber one side, steam water interface carries out energy and mass exchange through venturi and superfast expansion supercharging section, exhaust steam undergoes phase transition becomes high-temperature water, the latent heat of vaporization that low temperature water discharges when absorbing the exhaust steam phase transformation raises water temperature.Thereby heat energy and water to exhaust steam carry out second use, have saved a large amount of energy.
But, the flow that flow, pressure and the exhaust steam of low temperature water in the pump are reclaimed in existing water-jetting type exhaust steam all is by manually regulating according to working experience, the temperature of the high-temperature water that is produced is uncertain thus, and working strength is bigger, thereby makes some require more accurate operational site to be difficult to use to water temperature.
The model utility content
For overcoming above-mentioned defective, the utility model provides a kind of self-regualting type water that can regulate water temperature automatically to spray exhaust steam recoverer
For achieving the above object, the utility model self-regualting type water sprays exhaust steam recoverer, comprise that water sprays exhaust steam and reclaims pump, inlet end or steam inlet end at the described pump housing are communicated with the modulating valve that can adjust the valve opening amount according to control signal, water outlet end at the described pump housing is provided with temperature-detecting device, also comprise a controller, wherein the signal of temperature-detecting device exports the input end of controller to, and the signal output part of controller is connected with the signal input part of modulating valve.
After adopting said structure, utilize the temperature-detecting device of pump housing water outlet end to detect in real time to water temperature, and the temperature of detected water and default temperature are compared by controller, and the open amount of modulating valve is regulated according to comparison value, and then water is sprayed exhaust steam reclaim the inflow or the throttle flow of pump and regulate, make water temperature can remain predetermined value like this, thereby more effectively exhaust steam is utilized.
Description of drawings
Fig. 1 is the structural representation that the utility model self-regualting type water sprays exhaust steam recoverer.
Embodiment
As shown in Figure 1, the utility model self-regualting type water sprays exhaust steam recoverer, comprise that water sprays exhaust steam and reclaims pump 1, inlet end or steam inlet end at the described pump housing are communicated with the modulating valve that can adjust the valve opening amount according to control signal, modulating valve mainly is to be used for the signal exported according to the signal output part of controller regulating the valve opening amount of modulating valve, thereby the inflow or the throttle flow of water being sprayed exhaust steam recovery pump are regulated, and it can be various electric control valves.Water outlet end at the described pump housing is provided with temperature-detecting device, temperature-detecting device mainly is to be used for detecting water injection exhaust steam recovery to pump the temperature of mouth of a river water and produce the input end that temperature signal exports controller to, it can be all temps sensor, as thermocouple thermometer, thermistor etc.; Also comprise a controller, wherein the signal of temperature-detecting device exports the input end of controller to, and the signal output part of controller is connected with the signal input part of modulating valve.Controller mainly is according in advance temperature water to be sprayed exhaust steam to reclaim the temperature-detecting device that pumps place, the mouth of a river and detect comparison, and according to comparison value to the modulating valve output regulation signal, in order to the open amount of regulating valve.
Self-regualting type water of the present utility model sprays the exhaust steam recoverer working procedure: at first, earlier the water temperature that will reach is set in controller, it is in running order to make controller, modulating valve, temperature-detecting device and water spray exhaust steam recovery pump then, makes self-regualting type water of the present utility model spray exhaust steam recoverer water temperature is carried out real-time monitoring.When controller finds that the measured temperature of temperature-detecting device is lower than default temperature, then correspondingly reduce water and spray the inflow that pump low temperature water feed-water end is reclaimed in exhaust steam, or correspondingly add the throttle flow that big flood sprays exhaust steam recovery pump exhaust steam admission end, thereby make water temperature reach predefined value; When controller finds that the measured temperature of temperature-detecting device is higher than default temperature, then correspondingly, then correspondingly increase water and spray the inflow that pump low temperature water feed-water end is reclaimed in exhaust steam, or correspondingly reduce the throttle flow that water sprays exhaust steam recovery pump exhaust steam admission end, thereby make water temperature reach predefined value; So repeatedly, thereby the water temperature that makes water spray exhaust steam recovery pump remains on the predetermined value, thereby increases the value of exhaust steam.
