Pressure fluctuation type adsorption method

Abstract: PURPOSE:To further complete the regeneration of an adsorbent bed and improve the adsorption strength by maintaining the concentration of gas for regeneration use in the former half of the adsorption period for the regeneration of the adsorbent at a temperature higher than the adsorption temperature by a specific value, and supplying the gas to the absorbent. CONSTITUTION:A pressure fluctuation type adsorbing device comprises adsorption towers A1 and A2, changeover valves B1-B8 for changing the towers A1 and A2 over to the adsorption period and desorption period, reproduction gas heater C, and a reproduction gas flowpath changeover valve D. Valves B1-B8 can be automatically changed over in a predetermined sequence. In the above described organization, the raw material gas is caused to flow to a tower A1, and simultaneously the regeneration gas is caused to flow to the tower A2. In the former half of the adsorption period, the regeneration gas is caused to flow to the heater C only at a predetermined period of time through the valve D, and heated to a temperature more than the adsorption temperature by 10 deg.C or more. Thereafter, the regeneration gas is caused to flow to the tower A2 to apply heat to the adsorbent. After the lapse of a predetermined time, the valve D is switched to bypass the heater C, quantity of heat supplied to the absorbent by the regeneration gas at an ordinary temperature is extruded to the raw material gas flow-in side to cool the adsorbent whose temperature has been raised.

Metal strip heat treatment equipment

Abstract: PURPOSE:To effect uniform metal sheet heating by gas heater, a number of grooved gas return route is spacedly provided to plenum chamber on its face opposing to the metal sheet. CONSTITUTION:Metal sheet 5 to be heat treated is passed through prenum chambers 3,3 in the heating furnace 2. Heated gas is jetted from a number of nozzles 11 in the prenum chambers 3 to heat the metal sheet 5 from both side while floting the metal sheet 5. A number of gas return routes 12 is spacedly installed on the face 3a of the chamber 3 that faces the metal sheet 5. Gas jetted from the nozzles 11 impinges on the metal sheet 5 and flows at uniform velocity V toward both sides of the chambers 3 through end nozzles 10a and the return routes 12. Thus, heat gas flowing on the total area provides uniform metal sheet 5 heating.

Earthquake sensing automatic closing gas valve

Abstract: PURPOSE:To automatically interrupt the circulation of gas, by blocking an opening of a valve by rolling a sphere when earthquakes happen. CONSTITUTION:Gas enters a case from an inlet 9 before it is supplied to a gas heater and goes out from an outlet 10. When an earthquake happens, a sphere 2 falls from a pedestal 3, rolls in the case 1 and is stabilized at a location A where it is placed on a seat 4. If the seat 4 is made of an elastic material, the leakage of gas is perfectly prevented by the weight of the sphere. To return the sphere 4, a support plate 12 is brought down by demounting a coupling tool 14 connected to the case 1, the pedestal side of the case is lowered, and a light shock is given under this condition, thus the sphere 4 parts from the seat and rolls up to a location B.

Abstract: The heat pump using a boilder with a gas heater as in the main patent, also uses an auxiliary burner (1"). The boiler has a vertical cylinder (30) with a channel (33) through the middle through which passes the heat from the main burner (1') below. The auxiliary burner has a vertical tube parallel to the outside of the cylinder, with a line of flames (34) directed horizontally towards the cylinder. Both burner tubes are connected to the same gas supply tube (35) and the auxiliary burner has its own magnetically operated supply valve (36). The exhaust gases from the auxiliary heater travel around the cylinder and join the exhaust gases from the main heater at a point above the cylinder to pass through a common outlet (23).

Power generator using cooling gas

Abstract: PURPOSE:To obtain driving power by operating a turbine or the like while and reduce fuel consumption by re-circulating cooling gas such as Freon gas. To this end, use is made of expansion pressure due to the temperature difference of the cooling gas. CONSTITUTION:By causing rotation of a common shaft 6 with a starter, rotors 5, 10 and 19 of a cooling gas heater A, a drive power producing unit B and a cooling re-circulation unit C are rotated. When the rotation is continued until the low pressure in a cooling chamber 16 becomes zero, the cooling gas is forced into a heating case 1 of the heater A. At the same time, a heater 3 is operated to increase the gas pressure. When a valve 14 is subsequently opened, gas is issued through a duct 8 into the unit B. With this gas jet wings 12 are rotated in unison with the rotor 10, and the rotational force is taken out as drive power. Meanwhile, the gas from the unit B is supplied through a radiator 16 to the cooling chamber 16 so that its volume is reduced, and then it is supplied to a pump chamber 17.

Waste gas treating method

Abstract: PURPOSE:To improve the efficiency of an electrical dust precipitator by taking out part of a waste gas and controlling the same to a prescribed temp. then converting SO2 to SO3 and mixing the SO3-contg. gas as a humidity control agent with the supply waste gas to the electrical dust precipitator. CONSTITUTION:Part of a combustion gas exhausted from a boiler 1 is branched from a main flow channel 2 and is conducted through a flow channel 3 to a gas heater 4. The detection signal of a thermometer 11 provided to the outlet pipeline of the heater 4 is transmitted to a control device 12, where the output of the heater 4 is so controlled as to attain the prescribed temp. The waste gas having been heated to the prescribed temp. by the heater 4 is introduced into an oxidation catalyst reaction tower 5, where the contained SO2 is oxidized to SO3. The outlet gas in a reaction tower 5 is again returned to the main pipeline 2, through which it is conducted to an air preheater 6, where it is heat exchanged, and at the same time SO3 is adsorbed on the dust, whereby the specific electrical resistance of the dust is decreased. Thence, the waste gas is introduced into an electrical dust precipitator 7, after which it is released from a chimney 8.
