Problems solved by technology

When in use, the cooling water passed into the condenser, sometimes because the quality of the cooling water is poor, the water contains acidity or alkalinity, which will corrode the baffles in the condenser and affect the cooling effect of the condenser. Now it is commonly used The round-shaped baffle plate is easy to produce a flow dead zone at the position where it is welded with the tube wall of the heat exchanger, which greatly reduces the heat transfer effect of the heat exchange gas

Embodiment Construction

[0016] The present invention will be further described below in conjunction with the accompanying drawings. The baffle plate 1 is a circular baffle plate made of stainless steel, with a circular channel 2 evenly opened on the surface, and the opening area accounts for 60-90% of the total area. The round hole 2 is a through hole with a diameter of 8-20mm, and when the fluid passes through the round hole 2, the degree of turbulence of the fluid is increased. The diversion structure 3 is arc-shaped and welded to the circular end surface of the baffle 1, avoiding the right-angle transition zone formed at the welding position between the baffle 1 and the condenser, and eliminating the flow dead zone formed there. The anti-corrosion layer 4 is located at the outer end surface of the baffle 1 and prevents the corrosion of the baffle 1 containing acid or alkaline pairs in the water. The baffle plate 1 installed in the condenser, when the fluid in the condenser passes through the baff...

Abstract

The invention relates to a novel baffle plate. The novel baffle plate comprises a baffle plate, round holes, a flow guide structure and an anti-corrosive coating, wherein the baffle plate is a segment-shaped baffle and is made of stainless steel; round holes are uniformly formed in the surface of the baffle plate; an opening area of each circular hole is 60%-90% of an overall area; each round hole is a through hole with a hole diameter of 8mm-20mm; the flow guide structure is in an arc structure, and is welded on the round end face of the baffle plate so as to prevent a right-angle transition area from being formed at the welding position between the baffle plate and a condenser, and remove a flow dead area formed at the same position; the anti-corrosive coating is located at the outer end face of the baffle plate, so as to prevent corrosion on the baffle plate in the condenser, caused by an acidic solution or an alkaline solution. According to the baffle plate mounted in the condenser, when passing through the baffle plate mounted in the condenser, the fluid in the condenser flows through the round hole. The hole diameter is reduced and the flow-through speed of the liquid is accelerated, so that the flowing liquid is avoided in the condenser. The fluid flows with a certain radian in a transition manner through the flow guide structure of the baffle plate, so that the flowing dead area is overcome. The novel baffle plate provided by the invention has the advantages of simple structure and convenience for manufacturing.

Description

technical field [0001] The invention relates to an internal component used in heat exchange gas, in particular to a new type of baffle with a flow guiding structure. Background technique [0002] Heat exchangers are common equipment in chemical industry, petroleum, power, food and many other industrial sectors, and play an important role in production. In chemical production, heat exchangers can be used as heaters, coolers, condensers, evaporators and reboilers, etc., and are widely used. In the condenser, the baffle plays the role of enhancing the turbulent flow of the fluid flowing between the heat exchange tubes, thereby increasing the heat transfer coefficient, improving the heat transfer efficiency and supporting the tube bundle. When in use, the cooling water passed into the condenser, sometimes because the quality of the cooling water is poor, the water contains acidity or alkalinity, which will corrode the baffles in the condenser and affect the cooling effect of th...
