摘要： PURPOSE:To increase the operating efficiency of an adsorption/desorption tower by joining plural adsorption/desorption towers in the loop state so that these towers are changed over in order by providing pressure equalization time for an adsorption process and a desorption process in a pressure adsorption method. CONSTITUTION:The specified gas contained in gaseous mixture which has been introduced to each adsorption/desorption tower (A)-(H) from a compressor 03 for gaseous starting material is adsorbed and brought out from an outlet of each adsorption/desorption tower as gaseous product. The adsorption/desorption tower wherein the adsorption has been finished is changed over in order and joined and transferred to the desorption process. The adsorption/desorption tower wherein the desorption has been finished is joined with the adsorption/desorption tower wherein the adsorption has been finished and is transferred to a pressure equalization process and thereafter pressurized to the adsorption process. Thus, the adsorption process and the desorption process are repeated in the towers (A)- (H) through staggering the time by phase difference of pressure equalization time plus pressurization time.

摘要： PURPOSE:To improve the heat recycling efficiency by sealing a clearance between ceramic heat conductive elements and a joint area between the ceramic heat conductive element and corrosion resistant metallic material by corrosion resistant material, and by providing the ceramic heat conductive elements with a space inbetween. CONSTITUTION:The present packing member 11 is disposed from one end of a heat conductive element block 30 to the other end in a direction normal to a plane in which ventilating duct groups 20-1, 20-2 intersect perpendicularly with each other. Respective heat conductive elements 20 are disposed tightly in contact with each other through the packing material 11 such as asbestos cloth, fine flex ceramic fiber, mortar and water paste heat insulating material, etc. Moreover, in a case where the elements are disposed directly in contact with each other in the direction of the fluid flow as one arrangement method of the heat conductive elements 20, spaces (a), (b) of 20-30mm. width are provided in order to prevent the duct from being clogged due to narrowing opening area caused by a displacement between the openings.

摘要： PURPOSE: To contrive to recover heat over a wide range (to recover heat down to cryogenic range) by a structure wherein a non-leak steel type air preheater is installed against the high temperature portion, in which corrosion occur comparatively slightly, and a non-leak ceramic type air preheater is installed against the low temperature portion where corrosion occurs heavily, of exhaust gas.
CONSTITUTION: A non-leak steel plate type heat exchanger is employed as a preheater 3 of high temperature air, in which corrosion is comparatively out of question, and a non-leak ceramic type heat exchanger is employed as a preheater 6 of low temperature air, which has a temperature lower than the acid dew point of exhaust gas and consequently is of extremely corrosive atmosphere. Said two kinds of heat exchangers are combined so as to be installed in the order of the high temperature air preheater 3, a dry type electric dust collector 4, an induced draft fan 5, and the low temperature air preheater 6. Thus, the heat recovery down to a lower temperature range lower than before by about 30°C can be possible without being restricted by low temperature corrosion (sulfuric corrosion), from the aspect of which the heat recovery at the low temperature range of exhaust gas (the lowest tempeature limit of heat recovery is usually about 130W140°C of exhaust gas) is conventionally made impossible.

摘要翻译：目的：通过这样一种结构，在宽范围内回收热量（将热量回收至低温范围），其中将非泄漏钢型空气预热器安装在高温部分，其中腐蚀比较轻微地发生， - 低温陶瓷型空气预热器安装在排气严重腐蚀的低温部位。构成：采用非泄漏钢板式热交换器作为高温空气的预热器3，其中腐蚀相对不成问题，并且使用非泄漏陶瓷型热交换器作为低温空气的预热器6 ，其温度低于废气的酸露点，因此具有极大的腐蚀性气氛。所述两种热交换器按照高温空气预热器3，干式电集尘器4，引风机5和低温空气预热器6的顺序组合。因此，热量在不受低温腐蚀（硫酸腐蚀）限制的情况下，可以在低于以前降低约30摄氏度的温度范围内回收，从废气低温范围的热回收（最低）热回收的温度限制通常为废气的130-140℃）通常是不可能的。

摘要： PURPOSE:To keep a water supplying temperature at a low value and make an efficient removal of adhesive soot by a method wherein water is bypassed a preheating pipe to which adhesive soot is adhered during a normal operation to make a supply of water. CONSTITUTION:In case that an adhesive soot is produced at an outer surface of a low temperature preheating part 4a, water supplying change-over valves 11, 12 and 13 are changed over. Water supplying from the water supplying pump 8 is bypassed a low temperature preheating part 4a, passes through a valve 12 and then is guided to the high temperature preheating part 4b inclusive. In turn, hot temperature boiler circulation water of 170-180 deg.C is guided from the bypass pipe 14 and valve 13 through an auxiliary boiler drum 5, and the metal temperature of the low temperature preheating pipe 4a is increased up to a high temperature of 170-180 deg.C from about 90-120 deg.C at one to dry the soot adhered to the outer surface of the metal. With this arrangement, it is possible to make an efficient removal of adhesive soot without decreasing an amount of recovered heat.
