Description
Invention field
The present invention relates to a kind of application that is used to produce the system and the different purposes thereof of Blang's gas.
Background of invention
Sweet natural gas is generally used for family expenses and industrial purposes.Yet, act as a fuel the source to satisfy the needs that increase day by day to using Sweet natural gas, for example the worry of the heat supply of family and factory is increasing.Greenhouse discharge from combustion of natural gas comprises carbonic acid gas, sulfurous gas, nitrous oxide and water vapor.In fact, natural gas burning is considered to one of essential environmental factors of facilitating Global warming.The whole world that presents a contrast owing to the global shortage with natural gas supply needs to increase, and using another problem of Sweet natural gas is its secular economic feasibility, and availability.Other problem is that not all country all has the gas source of oneself, and therefore seriously depending on other country obtains Sweet natural gas.Also necessity exists a large amount of infrastructure networks to support supply, storage and the distribution of Sweet natural gas to the final user.Costliness is not only built and safeguarded to network at vast geographic exposure pipeline and final equipment, and be very easy to be subjected to external influence, for example the natural disaster or the threat of terrorism.
Propose several alternative fuel source and replaced Sweet natural gas.An example is to use sun power and is converted into feasible energy source.Another example is at US 4,081, the Blang's gas described in 656, and the content of this US 4,081,656 is combined in this by reference.Blang's gas is called as the energy source that is fit to that is used for pure industrial welding and cutting application.Particularly, US 4,081, and 656 have described that a kind of electrolysis by water produces oxygen and the method for the mixture of hydrogen.Product Blang gas has significant characteristic, high heating value for example, and can carry out the reactivity burning with selected metal and low pollution emission thing.
Several patents has been described the application of Blang's gas.For example, US 6,761, and 558 have described the heating installation that utilizes Blang's gas thermal response, and its content is combined in this by reference.It has further described the method for catching heat after Blang's gas is by hexane liquid from its reactivity burning.US 6,443, and 725 have described in the burner circulating combustion Blang gas method with heating heat production device, and its content is combined in this by reference.
Consider above-mentioned situation, in the current techniques developmental level, need reliable and safe system to supply family expenses and industrial energy as can be seen, thereby can satisfy the increase of energy requirement, and to the minimum that influences of environment.In addition, this explanation needs some row to have the new technology of these advantages.
For example, burning is usual way of eliminating pathogenic agent, virus and the toxic organic compound be present in most of families and the industrial waste.Yet conventional incinerator faces some problems more and more.For example a large amount of fuel of incineration plant consumption comes combustion waste.Fuel can comprise Sweet natural gas, propane or thin fuel oil.Because need increase and the whole world shortage of natural gas supply the whole world of Sweet natural gas, therefore traditional thermal incineration is for the very expensive means of waste treatment.In order to alleviate this influence, new incineration plant is positioned at from densely populated regional farther place, thereby causes the high transportation cost of refuse, fuel and other supply, because for the operation incineration plant, these all need through longer distance.
Another problem is owing to the incomplete combustion in the burning process of family and industrial waste dioxin and furans to be discharged in the atmosphere, causes the serious health threat to society.This has caused increasing from the pressure of environment, so that strict control and control have been forced in the treatment of wastes produced that produces dioxin and furans.Under the situation of high residence time of at least 2 seconds of the very chaotic mixing (utilizing forced ventilation) of refuse and stack gas, can in burning process, destroy De dioxin and furans in the combustion chamber effectively greater than 1200 ° combustion temperatures.Therefore, guarantee the perfect combustion of refuse and make that the minimized a kind of method of formation of De dioxin and furans is to improve the temperature of existing burning process with remarkable rising stove in the combustion processes, to improve efficiency of combustion.Yet this will cause the increase of running cost, and reason is that fuel combustion will increase.
Several alternative approach have been proposed to reach high temperature of combustion.An example is to change fluidized-bed propane incinerator into.Another example is to use the thermal plasma incinerator, and it is used to eliminate refuse with high energy, high-intensity plasma jet.Yet these methods can not directly be attached in the existing burning facility.Another kind method be utilize cheap, calorific value is high and have the alternative fuel source of minimum environmental influence.
In another example, airborne particulate matter emissions and flue gas emissions thing remain a general problem.Be known that extensively that also these discharges cause significant environment and health risk.These discharges may be produced by commercial run, coal combustion with from the burning facility of trash burning, and this only lists several.As the result of described effect (process), if be not discharged in the atmosphere under having situation about further handling, then the composition of discharge may be harmful to environment.
The existing measure of control and processing discharge and stack gas comprises the use of cyclone, electrostatic precipitator (ESP), settling pocket, wet scrubber and fabric filter system.Yet on big degree, these only help to reduce the particulate matter in discharge and the stack gas, and the composition of partially disposed stack gas and discharge.Therefore, when the discharge that will be somebody's turn to do " processing " and flue gas emissions were in atmosphere, discharge and stack gas still may contain might environmentally harmful composition.
For example, cyclone has low total particle collection effciency, particularly for the particle size that is lower than 10mm.Under the situation of ESP, although effective aspect processing discharge and stack gas, installation and maintenance is very expensive.They also need big installing space.And, in electromerism, may produce ozone by the electronegative electrode of ESP, this has increased environmental problem.Also may need the personnel of highly training to operate ESP.The fabric filter system also is expensive, and reason is when operating under surpassing about 290 ℃ temperature, needs the expensive refractory mineral or the fabric of metal.Also exist certain density some dust in the presence of unexpected Mars or flame, to explode and incendiary harm.
What address these problems under the circumstances, is favourable with the means with energy efficiency reliably on environment.
