摘要： PURPOSE:To improve a quality of placing concrete by cooling mixing water by making use of waste cold heat of liquefied gas effectively, by spraying concrete mixing water into discharge gas of the liquefied gas for cooling used for precooling of the concrete. CONSTITUTION:A concrete mixing water cooling device 1 possesses a mixing water storage tank 2 storing mixing water W, a discharge duct 3 discharging generated gas into the open air and a water feed and spraying device 4 spraying the water W within the discharge duct 3 by taking out the water W from within the mixing water storage tank 2. Liquid nitrogen is mixed into a cooling sand manufacturing mixer 11 through a liquid nitrogen feed pipe 12 and at the same time a pump 6 of the water feed and spraying device 4 is actuated. The liquid nitrogen mixed into the mixer 11 is mixed with sand S by an agitating blade 13, the sand S is precleaned, the liquid nitrogen is evaporated and moved forward toward a discharge port 3b as nitrogen gas having a temperature of 0 deg.C-50 deg.C. On one hand, the mixing water W is sprayed within the discharge duct 3 by passing through a spray nozzle 7 from the storage tank 2, heat exchange with the nitrogen gas is performed, cooled and recurs to the inside of the tank 2.

摘要： PURPOSE:To allow a wide variation width of cooling heat load by employing a plate fin type heatexchanger having three or more layers and controlling LNG flow corresponding to the low temp. load. CONSTITUTION:LNG sucked from LNG tank is fed through a LNG line 3 to a plate fin type heatexchanger 4. The heatexchanger 4 has a double layer structure, where low temp. layers 4-b for feeding LNG are arranged integrally at the opposite side of a heat receiving layer 4-a for feeding intermediate thermal medium. A circulation pump 7 having an inverter 8 is arranged in circulation paths 5, 5' for intermediate thermal medium where cooling heat loads 6-a, 6-b, 6-c are arranged in parallel. Flow control valves 9-a, 9-b control flow of LNG flowing through the heatexchanger 4 such that the temperature detected through an intermediate thermal medium temperature detector 10 is settled to a setting level.

摘要： PURPOSE:To prevent the coke deposition on a wall near a cracked gas introductory part of the titled apparatus with a small amount of a purging gas, by using a cracked gas introductory part separated from a wetted wall and an introductory part for oil, etc. provided in a purging gas region provided after the purging gas introductory part. CONSTITUTION:The end part of an inner cylinder 1 in a heavy oil cracking apparatus is a cracked gas introductory part 2, and whole periphery of the cracked gas introductory part 2 is a purging gas introductory part 4 in the gap part between the outer cylinder 3 and inner cylinder 1. A purging gas is jetted from the purging gas introductory part 4 at a lower speed than that of the cracked gas, and a purging gas region 6 free from the entry of the cracked gas is formed after the purging gas introductory part 4. An introductory part 8 for oil or water is constructed for forming a wetted wall 5 in the purging gas region 6 to prevent the collision of particles in the cracked gas with the wetted wall 5 near the cracked gas introductory part 2.

摘要： PURPOSE:To prevent breakage and wear-out of a valve seat surface and improve sealing performance by increasing the contact surface of the valve seat of a slide valve and improving the accuracy of surface finishing and utilising the fine powder slurry which enters into between the valve contact surfaces as sealing agent. CONSTITUTION:On the taper supporting surface 6 on the inflow port 1 side of the valve case 3 having the inflow port 1 and an exit port 2, the wedge-shaped valve seat 8 having a seal ring 7 installed inside is installed, and a parallel valve seat 10 is installed through a gasket 9 on the exit port 2 side. Between the both valve seats 8 and 10, a valve plate 11 is installed, and this valve plate 11 ascends and descends following the movement of a valve rod 13 through a top 12. On the valve plate 11, a valve plate hole 14 is opened. In valve opening and closing operation, the valve plate 11 is always slided onto the valve contact surfaces 8 and 10, and a wide contact area can be held, and the valve contact surfaces 11 and 11' are possible to have sufficient surface finishing precision.
