Study on the dust collection on wet basis and the desulfurization of the smoke from the coal-fired boiler
An apparatus for combining the dust collection with the sulfurization in it is developed to have entirely changed the existing modes for dust collection and desulfurization, thus bringing about an innovation on the dust collection and desulfurization technology for the coal-fired boiler to have realized over 99.5% dedusting rate and over 90% desulfurization rate for the smoke.

Condenser
The condensing reaction is made on the smoke from the electrolyzer by means of condensing electrostatic purification technology to increase condensation of the subparticles of pitch in the smoke so that a bigger aggregate of polarized particles is formed between the pitch smoke, thus enhancing its electric charge capacity, adsorbing a layer of alumina power on its outside and losing its viscosity, without and sticking to clogging the filtering bags and pipes. And then the adsorption reaction and the gas-solid separation are made on it successively.Research

Desulfuration and Denitration Technology with Plasma at Low Temperature and Normal Pressure
The high-concentration and high-energy plasma is generated by electric discharging from corona at ultra-high voltage pulses (Marginal value of pulses of 180 to 360 KV, 1μS pulses width and 50 to 10000 Hz) to make the gas of the electric field (reactor) remain in a state of excitation and activation to provide the chemical reaction of the gas in the electric field with an enormous quantity of active particles so as to carry out a given chemical reaction and generate the products as required, which can break off the chemical links of SO2 and NOX gases in the pulsating electric field under high-voltage at ultra critical intensity of the electric field to decompose the SO2 and NOX gases into a single solid of single mass S, a single gas of single mass O2 and a single gas of single mass N 2.

Desulfurization technology by oxygenization-thermochemical process
For the desulfurization technology by oxygenization-thermochemical process, the ultra-high-voltage pulsating corona electric discharging is used in combination with the catalyst to make the SO2 gases blended effectively with NH3 after the SO2 gases is thoroughly oxygenized in the oxygenization dust collector and the chemical reactor, over 90% of which has become solid particles via chemical reaction that will be effectively recovered by oxygenization recuperator.
With this technology the smoke undergoes Intensive oxygenization chemical reaction in the oxygenization reactor to generate gaseous H2SO4. NH3 gas is directly sprayed into the reactor by using the chemical kinetic process to be directly reacted with H2SO4to generate (NH4)2SO4; thus having realized desulfurization on dry basis without generating any pollutants and saved an enormous volume of work to treat a large volume of effluent from desulfuration on wet basis, without any rejects. The recovered of practical value for use to compensate for the costs of chemicals for NH3. Today, oxygenization-thermochemical process is a rather optimum new technology for desulfurization that recovers new valuable products on dry basis, without the necessity to use additional energy, with simplified equipment, low investment once for all and low operating costs.

Ammonia synthetizing technology with ultra-intensive pulsating electric field.
N2 and H2 gases are mixed at a certain ratio and then the high-concentration non-equilibrated plasma is generated by discharging from collision of the anode against the cathode in he cavity of the reactor under the action of the high electrolytic material (Porcelain body BaTiO3) with ultra-high voltage narrow pulse and high-frequency and high-voltage pulse field to make the gas molecules N2 , H2 and others become active particles such as N, H and others of the single atom after the gas molecules have undergone nonelastic effective collision to have generated excitation and ionization thus becoming free bases, forming active particles such as N, H and others of the single atoms, and the N and H atoms in high activated state are synthesized into NH3 molecule. According to the results of the tentative experiment, the concentration of synthesized NH3 is up to 5000 ppm. This technology is carried on at low temperature under normal pressure, without the necessity to use the vaccum system and the closely-sealed reactor with vaccum hood, thus providing the synthesization of the inorganic substance with a new process with low energy consumption and simplified equipment.

Bacteria extermination technology for food with ultrahigh pulse magnetic field
Recently, our Institute has succeeded in development of the bacteria extermination technology with ultrahigh pulse magnetic field. With this technology, the food is put into the ultrahigh pulse magnetic field for treatment, using the air as medium to conduct ultrahigh pulse magnetic field, thus serving the purpose for killing bacteria at room temperature, preventing the nutrient elements of food from being destroyed both avoiding pollution, without altering the colour and taste of food. For this technology it can be used to kill bacteria not only for packing various liquid beverage, but also for pastry, preserved fruits, dried fruit, poultry meat, eggs, fish and other solid food. And therefore it is an optimum technological process for killing bacteria and it is expected to replace the high-temperature and high pressure thermoprocess for killing bacteria and become the food processing method for 21 century.
