Description
Technical Field
The utility model belongs to the technical field of shell and tube heat exchanger, concretely relates to shell and tube heat exchanger mouth of pipe protective sheath.
Background
At present, technologies such as thermal compression, mechanical compression and the like are widely applied to a multi-effect evaporation system, the multi-effect evaporation technology is mainly a series evaporation operation taking secondary steam of a previous effect as heating steam of a next effect, and in the multi-effect evaporation system, the operation pressure, the corresponding heating steam temperature and the solution boiling point of each effect are sequentially reduced, so that the energy consumption ratio of multi-effect evaporation is further reduced, and the efficiency is far higher than that of single-effect evaporation. The shell-and-tube heat exchanger as an important device of a multi-effect evaporation system mainly comprises a shell, tube plates, a heat exchanger and the like, wherein the heat exchanger is connected to the tube plates, and the tube plates are respectively welded at two ends of the shell. Two kinds of fluid with different temperatures are arranged outside and inside the tube of the heat exchanger, the heat exchanger tube is used for heating fluid inside the tube and condensing gas outside the tube, when heat exchange is carried out, the fluid enters from the tube opening of the heat exchanger, is heated inside the tube and flows out from the other end of the heat exchanger.
In a multi-effect evaporation system, heat exchanger nozzles are used to connect fluids inside the system in series, and when the fluids flow through the nozzles, the turbulence created by the fluid flow tends to cause erosion and corrosion of the heat exchanger nozzles. In order to prevent the fluid from scouring and corroding the pipe orifice when the pipe orifice of the heat exchanger is produced, a pipe orifice protective sleeve is required to be used for protecting the pipe orifice of the heat exchanger, and the problems of disassembly and assembly are solved in the using process.
SUMMERY OF THE UTILITY MODEL
In order to solve the technical problem, the tube orifice protective sleeve for the tube type heat exchanger is provided, so that the tube orifice of the heat exchanger is protected from being washed and corroded by fluid during production, and meanwhile, the tube orifice protective sleeve is easy to disassemble and assemble.
The technical scheme of the utility model is that: the utility model provides a shell and tube heat exchanger mouth of pipe protective sheath, includes first pipe, limit structure, first pipe external diameter equals shell and tube heat exchanger mouth of pipe internal diameter, outwards bulge in first pipe middle part first pipe bulge part processing has rectangular shape through-hole, rectangular shape through-hole with first pipe the central axis is parallel, rectangular shape through-hole is the array along circumference and arranges. One end of the first round pipe is provided with the limiting structure.
The limiting structure comprises a second round pipe and a round ring, the inner diameter of the second round pipe is larger than the outer diameter of the first round pipe, the inner diameter of the round ring is equal to the outer diameter of the first round pipe, the outer diameter of the round ring is equal to the inner diameter of the second round pipe, one end of the first round pipe is fixed to the inner diameter of the round ring in a sealing mode, and one end of the second round pipe is fixed to the outer diameter of the round ring in a sealing mode.
When using, insert the first pipe in shell and tube heat exchanger mouth of pipe, the part of bulging gets into the shell and tube heat exchanger mouth of pipe back along with first pipe, under the effect of the part elasticity of bulging, and produce the extrusion between the shell and tube heat exchanger mouth of pipe and can fix shell and tube heat exchanger mouth of pipe protective sheath, after first pipe and second pipe junction and shell and tube heat exchanger mouth of pipe contact are spacing, shell and tube heat exchanger mouth of pipe protective sheath is installed promptly and is in place, shell and tube heat exchanger mouth of pipe protective sheath is installed behind the shell and tube heat exchanger mouth of pipe, can dismantle shell and tube heat exchanger mouth of pipe protective sheath through outwards applying external force to the second pipe.
The utility model discloses following beneficial effect has: 1. when the shell and tube heat exchanger works, fluid flows through the tube orifice of the shell and tube heat exchanger, and the outer diameter of the first round pipe is equal to the inner diameter of the tube orifice of the shell and tube heat exchanger, so that the tube orifice protective sleeve of the shell and tube heat exchanger can isolate the fluid from directly contacting with the tube orifice of the shell and tube heat exchanger, and protect the tube orifice of the shell and tube heat exchanger from being scoured and corroded; 2. tube array heat exchanger mouth of pipe protective sheath, can fix through the part of bulging, also can apply external force and dismantle tube array mouth of pipe protective sheath, the installation is convenient with the dismantlement.
