Abstract
The invention relates to an efficient energy-saving and environment-friendly stainless steel heat treating machine. The efficient energy-saving and environment-friendly stainless steel heat treating machine is mainly formed by a pure oxygen supply system, a natural gas supply system, a combustor, a control system and a furnace pipe; a buffer tank is a pressure container; the furnace pipe contains protective gas; the natural gas outlet pipe of the natural gas supply system is connected with the natural gas inlet pipe of the combustor; a temperature sensor is connected with a control center of a computer; a solenoid valve is connected with an instruction transmission system of the control center of the computer; the control center of the computer acquires information from the temperature sensor and realizes match of supply of natural gas and pure oxygen according to the requirement of the system on temperature; and the solenoid valve is used for executing the instruction of the control center of the computer to realize match of supply of the natural gas and the pure oxygen, so as to instantly control system temperature. The efficient energy-saving and environment-friendly stainless steel heat treating machine has the advantages that energy conservation and emission reduction are achieved, and new standard of exhaust gas emission is rewritten and formulated.
Description
Technical field
The invention belongs to Field of Heat-treatment.
Background technology
Hot-rolled stainless steel wants annealed pickling, annealing and pickling Main Function carries out solution treated to hot rolled strip and removes surface scale, solution treated part has been come primarily of annealing furnace, annealing furnace is divided into four parts, preheating section respectively, heating zone, cooling section, dryer section, in prior art, preheating section and heating zone are all add the heating of air-breathing burner to reach the object of the heating that heats up by Sweet natural gas, but in Sweet natural gas and air combustion process, owing to containing oxygen 21% in air, the instantaneous rate of combustion effectively of Sweet natural gas is reduced greatly, cause waste resource and the energy, contaminate environment air, the energy effectively rate of utilization significantly reduces.
Summary of the invention
A kind of stainless steel hot handler of high-efficient energy-saving environment friendly, air-breathing is replaced with pure oxygen, Sweet natural gas is 1: 2 with the combustion oxygen ratio of pure oxygen, and the fuel air ratio of Sweet natural gas and air combustion is 1: 10, the nitrogen reducing about 80% in the middle of this is invisible participates in combustion reactions, result is: combustion tail gas reduces 80%, the energy that tail gas is taken away reduces 80%, save energy, generation oxynitride is at high temperature reacted without nitrogen and oxygen, not only save oxygen, and thoroughly reduce discharging oxynitride, decreasing pollution environment, moreover oxygen concentration is only 21% of pure oxygen in air, so Sweet natural gas in pure oxygen combustion velocity be about 25 times of Sweet natural gas combustion velocity in atmosphere, not only energy-conservation, and reduce discharging, the technical scheme of specifically dealing with problems is: a kind of stainless steel hot handler of high-efficient energy-saving environment friendly, and the stainless steel hot handler of described high-efficient energy-saving environment friendly forms primarily of pure oxygen feeder system, natural gas supply system, burner, Controlling System and flue, described Controlling System is mainly made up of computer controlling center, temperature sensor and magnetic valve, described pure oxygen feeder system is mainly made up of liquid oxygen tank, vaporizer, surge tank and connecting tube, described liquid oxygen tank liquid oxygen output tube is connected with vaporizer liquid oxygen input tube, vaporizer oxygen output tube is connected with surge tank oxygen input tube, and surge tank oxygen output tube is connected with the oxygen input tube of burner, described liquid oxygen tank is double container, internal layer is pressurized vessel, skin is vacuum vessel, internal layer container splendid attire liquid oxygen, vaporizer be fixed on two-layer inside and outside outer layer container inwall between, inside and outside two-layer between vacuumize, the space between internal layer container and outer layer container is filled with the wrapped internal layer container outer wall of multilayer insulant or thermal insulation material, described surge tank is pressurized vessel, described flue is the flue with shielding gas, described burner is the burner that Sweet natural gas adds pure oxygen, the gas outlet pipe of described natural gas supply system is connected with burner natural gas inlet pipe, described temperature sensor is connected with computer controlling center, described magnetic valve is connected with the command transmission system of computer controlling center, described computer controlling center obtains information from temperature sensor, according to the requirement coupling Sweet natural gas of system to temperature and the supply of pure oxygen, described magnetic valve is that computer controlling center instruction execution realizes body, performs the supply realizing coupling Sweet natural gas and pure oxygen, realizes Controlling System temperature to instantaneous.Its advantage is: save energy, and decreasing pollution discharges, and rewrites exhaust emission standard, formulates the brand-new standard of exhaust emissions.
