Title: Dechlorination of kraft pulp cooking waste liquor
Inventor: SATO HIROYOSHI
IPC: C02F9/00
Filed: 1991-12-24
Abstract: PURPOSE:To accomplish the subject dechlorination without causing cooking efficiency decline by treating with an electrostatic precipitator the exhaust gas produced by combustion of kraft pulp cooking waste liquor followed by spraying water into the exhaust gas to wash the gas to effect dechlorination to prevent the equipment from corrosion followed by desulfurization through a conventional process. CONSTITUTION:In recovering chemicals by combustion of kraft pulp cooking waste liquor, black liquor (a) as the cooking waste liquor is combusted in a recovering boiler 1, the resulting smelt (b) is fed to a dissolver 2 where the chemical liquor is regenerated, and the exhaust gas c produced by the above combustion is treated in an electrostatic precipitator 3. The resulting exhaust gas (c) is sent to a dechlorination column 4 where water is sprayed into the gas to wash the gas; in this case, part of the effluent is used as recycled water, through circulation with a pump together with newly replenished fresh water, thus carrying out dechlorination (the chlorine ion is separated and removed in the form of hydrogen chloride). Then, the exhaust gas dechlorinated is brought to a desulfurization column 5 where the gas is desulfurized through a conventional process, thus accomplishing the objective dechlorination without causing cooking efficiency decline with the equipment prevented from corrosion.

The brushes are pressed to the unnecessary films on the substrate in this position to mechanically scrape the unnecessary films. Next, a 90 deg. rotating mechanism disposed in the substrate transporting section is actuated to rotate the substrate 90 deg.. The brushes are again pressed in this position to the unnecessary films on the substrate and the unnecessary films are mechanically scraped. Consequently, the treatment of the end face parts over the entire circumference of the substrate is executed.

Title: Manufacturing device of tetra-shaped packaging body
Inventor: SUZUKI SANJI
IPC: B65B29/02
Filed: 1991-12-30
Abstract: PURPOSE:To prevent wrinkles from generating at the time of lateral sealing to improve the appearance, and at the same time prevent the content from leaking out by pressing the packaging material from both sides at the time of lateral sealing. CONSTITUTION:A tetra shaped packaging body is manufactured by forming first and second lateral sealings, which are mutually rectangular, on a cylindrical shape packaging material 9 by rotating a lateral sealing means at each 90 deg.. The pressing by pressing plates 51, 52 presses the packaging material 9 from both sides at the time of these lateral sealings to fix the packaging material 9 at the time of lateral sealing. Also, a gas injection is performed prior to the pressing by the pressing means and lateral sealing by the lateral seal means, by injecting a gas from injection nozzles 42, 44 and injection nozzles 41, 43 respectively in the packaging material 9. Since this injection is performed in the same direction as the lateral sealings, the packaging material 9 is extended into a flat shape in the sealing direction and wrinkles are prevented from generating on the packaging material 9. For this reason, the lateral sealings can be perfectly performed.
