Art
The present invention relates to the energy-conservation and control system device of a kind of heat treatment kiln, especially by utilizing solar energy heating and the automatic control realization Heat Treatment Energy Saving of circulating pump.
Background technology
At present, known heat treatment kiln all adopts boiler heating steam in the world, and high-temperature steam conducts to fin in kiln, by promoting kiln temperature after high-temperature steam heating fin, finally realizing kiln temperature and rising.The main supplying heat source of this traditional heat treatment mode is boiler, the heat supply of boiler must use a large amount of fuel, very large pollution can be caused to environment, and, by our experimental study, adopting different kiln temperature to carry out heating can improve capacity usage ratio, realizes energy-conservation, but the heat supply of boiler cannot realize automatically controlling according to kiln temperature at present, and Artificial Control is unrealistic again.Therefore, existing heat treatment kiln energy waste is comparatively serious, and Energy Saving Control means are immature.
Summary of the invention
In order to solve heat treatment kiln energy consumption higher than problems such as Energy Saving Control means are immature, the invention provides a kind of energy-conservation and auxiliary automatic control system, this system can be saved the energy consumption of heat treatment kiln boiler from many aspects and improve automatic control means.
Along with in the world to the progressively understanding of energy-conserving and environment-protective, the development of solar energy heat collection equipment and the maturation of automated control technology,
The present invention solves the technical scheme that its problem adopts: transform at boiler water supply water tank, solar energy heating circulation turnover (cold and hot) water pipe is set, circulating pump and autocontrol valve is provided with between solar thermal collector and boiler water supply water tank, solar thermal collector is connected with heat treatment kiln inner radiator simultaneously and is furnished with autocontrol valve, in heat treatment kiln, increase temperature sensor and connect Programmable Logic Controller, increase between boiler and kiln inner radiator and can control circulating pump and valve, above circulating pump and valve are all connected with Programmable Logic Controller and control by it.For realizing energy-conservation and automatic control, the first, boiler water supply heating water tanks can be realized by solar thermal collector, circulating pump, improving boiler water supply water temperature, realizing energy-conservation; The second, improve heat treatment kiln initial temperature by the work of solar thermal collector, circulating pump, kiln inner radiator, the shortening heat process overall time, realize energy-conservation; 3rd, by temperature sensor, Programmable Logic Controller, controlled circulating pump and valve, kiln temperature is set to energy efficiency temperature interval, by circulating pump and the valve of Controlled by Programmable Controller whole system, realizes auto-controlled energy-saving.
The invention has the beneficial effects as follows, improving boiler water supply temperature by solar energy heating realizes energy-conservation, utilizing solar energy heating to improve heat treatment kiln initial temperature realizes energy-conservation, and realize the energy hole that kiln temperature controls heat treatment heating automatically, automatic control realization can be utilized energy-conservation by setting energy efficiency temperature, use simple, automatic controlling extent is high.
