The present invention relates to a nozzle for flowing fluid into and out of a tank, such as a tank for storing the fire-coating medium or a heat exchanger for recovering waste heat from the waste water. More specifically, the main body of the main body is formed of carbon steel, and the inner surface is corrosion resistant. In the tank to which the cladding material of the main body is press-molded, the nozzle for welding and supplying the fluid into and out of the tank is welded to the mother body of the main body, and the inner surface of the nozzle has the same corrosion resistance as the cladding material of the main body or alloy material. In forming the sleeve, the flange of the nozzle opening and the inlet of the lining sleeve are completely formed by the lining sleeve being double welded by the back sheet ring and the seat ring to the carbon steel of the nozzle. Sealing prevents the fluid flowing into the nozzle from leaking from the corrosion resistant material to prolong oxidation and corrosion of the carbon steel material. And, also it relates to the structure of the chemical liquid tank to raise the first floor nozzle for the reliability of the product.

In general, a heat exchanger, a reactor, and a pressure base body for recovering waste heat from a tank or a waste water storage wastewater are formed of a carbon steel material, and an inner surface of a corrosion-resistant clad material such as titanium and zirconium. It is press-molded to prevent corrosion by fluid flowing in and out of the tank.

It is possible to form a single corrosion resistant member without double the structure of the tank as described above, but the main body of the titanium and zirconium, such as the price is not only expensive, but also difficult to machine processing and the processing cost is high Is made of carbon steel and corrosion-resistant member is used as clad material.

In addition, nozzles for supplying and flowing fluid to and from heat exchangers, reactors, and pressure primitives for recovering waste heat from the tanks or wastewater storing the fibridant are usually made separately from the mother of the main body, and welded to the main body. It is integrally bonded to the parent.

In the nozzle, a lining sleeve material is formed of the same or the same alloy material as the clad material in the same manner as the clad material is formed in the matrix of the main body.

Since the main body of the main body forms a cylindrical body by drying a disk of a certain thickness into a cylindrical shape, the area where the nozzles are joined is formed into a curved surface with a deviation, and the curved surface and the inner surface of the nozzle also have a curved surface and the inner surface of the nozzle flows in and out of the fluid. In order to minimize the interference of the fluid in the lining, the inner surface lining for sealing the curved portion of the base of the nozzle and the opening of the mother body of the main body is formed, and the cylindrical lining sleeve mounted on the inner surface of the nozzle The upper end of each of the lining sleeves is sealed with a gasket and a welding treatment on the flange of the nozzle, and the base of the lining sleeve is sealed with a welding treatment with the upper end of the inner lining. The end of is to be sealed by the cladding material and welding treatment of the mother body of the main body.

Since the nozzle is a fluid flow part, when the leakage occurs at the upper end of the lining sleeve, which is a joint between the carbon steel part of the nozzle and the lining sleeve, and the welding part of the gasket on the flange part of the nozzle, the highly corrosive fluid is lining. Inflow into the sleeve results in corrosive oxidation of the carbon steel of the nozzle.

In particular, since the upper end of the lining sleeve and the gasket on the flange of the nozzle are welded together, they are welded to the extent that the lining sleeve is connected to the gasket, and the welding part is fatigued by fastening bolts and nuts to the flange of the nozzle. The stiffness of the lining sleeve is required, and if the welding treatment is somewhat poor, it can cause leakage immediately.

The present invention is to solve the above problems, the base of the lining sleeve of the nozzle is sealed with the upper end of the inner lining and the welding treatment, and the end of the inner lining is welded to the clad material of the mother body of the main body and the welding treatment When the sealing condition is formed, the cylindrical lining sleeve and the inner lining are manufactured by integral molding so that the end of the inner lining can be welded to the cladding material of the mother body of the main body. The lining sleeve and the same and homogeneous alloy sheeting are welded to the end of the lining sleeve in the joining to the flange portion of the nozzle at the upper end of the sleeve. Lining sleeves, sheetings and backsheetings are formed by forming the backing rings of the same and same alloy materials It is welded to increase the stiffness of the cladding on the flange of the nozzle, and the welded joint of the cladding material is kept airtight by the three cladding materials, which prevents the fluid from flowing into the carbon steel of the nozzle due to leakage. It is intended to provide a structure of a nozzle for a tank.

In the present invention, a clad material is formed in a mother body of a main body tank, and a lining sleeve is formed in a mother body of a nozzle for circulating fluid in the tank. The back sheet ring is mounted between the lining sleeve and the seat ring while the ring is welded, so that the ring seat is fixed together with the lining sleeve and the seat ring.

The lining sleeve, the seat ring and the back seat ring of the present invention are made of a material such as titanium or zirconium, which is a corrosion resistant material of the same type, even if the fluid is stored in the tank that causes severe corrosion. Can be.

The configuration of the present invention will be described in detail with reference to the accompanying drawings.

As described above, the cladding material 110 of the cladding member 110 may be formed in the matrix 100 of the main body of the tank 10. By pressing, the highly corrosive fluid blocks the inflow of the main body 100 to prevent corrosion and oxidation, and the main body 100 of the main body even in the matrix of the nozzle 200 circulating the fluid in the tank 10. Similarly, lining sleeves 210 of corrosion resistant materials such as titanium and zirconium are formed.

As shown in FIG. 2, since the mother body 100 of the main body forms a cylindrical body by drying a disk of a predetermined thickness into a cylinder, a portion where the nozzle 200 is joined is formed into a curved surface with a deviation, and the nozzle 200 ) Is made of carbon steel material and the curved surface and the inner surface of the nozzle also have a deviation as shown in FIG. 3 so as to minimize the interference of the fluid to the inflow and outflow of the fluid by the surface treatment, the nozzle 200 is welded to the mother body of the main body. It is fixed.
