Description
Technical field
The invention belongs to chemical technology field, be specifically related to a kind of equipment utilizing factory's flue waste-heat dissociated methanol to produce combustion of hydrogen use.
Background technology
Fossil oil, as the economy of modern society and basic substance, serves support function in social development process.Along with Economic development and population growth, the demand of the energy continues to increase, and has occurred the significant problem that fossil energy shortage and environmental pollution etc. are urgently to be resolved hurrily, therefore, has sought the direction that new substituting novel energy is following national energy Sustainable development.
Hydrogen, as the renewable new forms of energy of one, has the features such as high, the clean zero release of calorific value, industrially has been widely used.The preparation method of hydrogen has a variety of, as water electrolysis hydrogen production, natural gas hydrogen preparation, light alkane vaporize hydrogen manufacturing, coal steam reformation hydrogen production and methanol decomposition hydrogen manufacturing etc.Compared with other several preparation methods, methanol decomposition hydrogen manufacturing has the features such as cost is low, technology maturation, energy consumption are low.Existing methanol decomposition hydrogen producer is varied, but these equipment can only work in narrow temperature range, and is not also arranged on the methanol decomposition equipment that factory's flue utilizes the hydrogen manufacturing of used heat dissociated methanol at present.
The invention discloses that a kind of investment is low, simple to operate, security is high, widely used Multifunction methanol decomposition hydrogen producer.
Summary of the invention
Multi-function methanol cracking hydrogen production equipment of the present invention, is characterized in that equipment is primarily of compositions such as (1) methanol pump, (2) diesel oil pump, (3) magnetic valve, (4) nozzle, (5) operator's console, (6) gas blower, (7) blast inlet, (8) methanol pyrolyzer, (9) airheater, (10) temperature sensor, (11) air-cooler, (12) anti-explosion safety cylinder, (13) impeller pump, (14) chilled water tank, (15) gas samplers.
Multi-function methanol cracking hydrogen production equipment of the present invention, can be divided into two analog operation stages, and first stage simulation industrial flue, utilizes the hydrogen manufacturing of plant emissions used heat dissociated methanol; Subordinate phase simulation industrial furnace, the hydrogen that stove combustion methanol decomposition is obtained.
First stage, operator's console Controlling solenoid valve and diesel oil pump, a certain amount of diesel oil is sprayed in methanol pyrolyzer cavity through nozzle, the a certain amount of air inputted by gas blower and blast inlet of proportioning simultaneously, ignition, make methanol pyrolyzer cavity combustion to close with actual flue temperature, regulate wind speed and oil mass holding temperature by temperature in temperature sensor reaction cavity.Methanol pump can pass through operator's console Controlling solenoid valve, enters in methanol pyrolyzer cracking tube carry out cracking via nozzle.When applying in actual industrial process, can according to flue temperature, the cracking tube changed in Multi-function methanol cracker carries out scission reaction.
The hydrogen that cracking obtains, after cooling system cooling, by gas sampler sample examination, gathers the cracked gas composition under differing temps.
Subordinate phase, by obtained hydrogen, a certain amount of air of proportioning, enters in the cavity of methanol pyrolyzer by blast inlet, replaces diesel oil and burns, and is equivalent to simulate industrial furnace.Because the calorific value of hydrogen is high, the high temperature of 1300 DEG C can be reached, and post combustion emission cleans, and industrially has purposes greatly.Flue gas in addition after burning can be detected by the detection mouth of chimney.
The following measures for the prevention of explosion of this equipment de-sign: hydrogen cooling system adopts water seal, prevents the tempering of gas suck-back.Safety explosion-proof tank tank mouth is aluminium foil safety anti-explosive mouth, and T-valve is installed in side, and T-valve outside is safety valve and check valve, prevents device interior pressure excessive.In whole equipment, pressure is a little more than external pressure, can not produce extraneous gas and invade the explosion hazard caused.
Multi-function methanol cracking hydrogen production equipment of the present invention, invest low, simple to operate, security is high, be widely used.According to this equipment principle transformation size industry or civilian burning coal, burning diesel oil boiler, additional energy can not consumed, make use of used heat, create the hydrogen of clean high heating value.While remarkable in economical benefits, greatly reduce environmental pollution.
Except industrial, this equipment can also be applied to data gathering and the academic research of methanol decomposition hydrogen manufacturing.
