A kind of heat exchanger of material containing stereoplasm

Technical field

The utility model relates to a kind of heat exchanger, especially a kind of heat exchanger of material containing stereoplasm belongs to technical field of heat exchangers.

Background technique

Heat exchanger is a kind of heat exchange equipment for being used for thermal energy (enthalpy) transmitting and converting, and the transmitting and converting process of thermal energy (enthalpy) is The mode of diabatic process, diabatic process generally includes: heat transfer, thermal convection or heat radiation;Thermal convection usually occurs at two kinds not When synthermal media contact, for example, different temperatures the thermo-contact of two or more fluids when or fluid connect with the surface of solids When touching or when fluid is contacted with solids, heat can be transmitted from high-temperature medium to cryogenic media.Heat exchanger chemical industry, In oil refining, metallurgy, power transmission, environmental protection and other industrial circles, there is universal application.Existing heat exchanger mainly has Shell-and-tube heat exchanger, plate heat exchanger, movable tube sheets heat exchanger, jacketed type exchanger.

In sludge treatment field, often need to carry out heat exchange to the material containing stereoplasm of solid content 8%-18%, it is this to contain stereoplasm Expect that solid content is higher, and be often mixed with the substances such as hair, staple fiber in material, these substances are liable to stick to shell, plate-type heat-exchange On the feed inlet or plate of device, and other solid particles are adsorbed, form blocking, cause heat exchange equipment that cannot stablize longtime running, Repair and maintenance heavy workload.Existing double pipe heat exchanger in petrochemical industry using relatively broad, it is advantageous that it is high pressure resistant, Resistant, anti-blocking property is preferable, the disadvantage is that heat transfer efficiency is lower.

Utility model content

In view of the above-mentioned problems, the utility model provides a kind of heat exchanger of material containing stereoplasm, and it is simple and reliable for structure, it is suitable for containing solid The material containing stereoplasm and water for measuring 8%-18% exchange heat, and stability is strong, is not easy to plug, and pipeline is not susceptible to deformation.

The technical scheme adopted by the utility model to solve the technical problem is as follows: a kind of heat exchanger of material containing stereoplasm, by cleaning Import, material inlet pipeline, material inlet, circulating water outlet, material outlet, washing outlet, circulating water intake, casing, branch pipe, Inner tube, braced frame, bearing piece, U-tube part composition.Material inlet by material inlet piping connection inner tube, said inner tube be by More root canal roads are connected the tube side to be formed, and are successively connected by U-tube part, inner tube and the runner tube wall that U-tube part forms are smooth, play The effect of anti-blocking, material containing stereoplasm flow in inner tube, and clear water flows in the annular gap that inner tube is formed with casing, solid with containing Slurry process forms adverse current, and logarithmic temperature difference is larger, therefore heat transfer efficiency is high, and described sleeve pipe and material inlet line connection are arranged Circulating water outlet is equipped with cleaning import above material inlet pipeline, between described sleeve pipe tube wall and inner pipe wall every one section away from From three to four bearing pieces of setting, it is ensured that clamp sleeve layer flow area is annular, is provided with branch pipe, branch pipe between the every row of described sleeve pipe Inside is not provided with inner tube, internal circulation clear water, and described sleeve pipe lower section side connects material outlet, circulating water intake, washing outlet.

Described sleeve pipe quantity is longitudinal direction 6-16 row, transverse direction 1-4 row.

The branch diameter is 0.6-0.85 times of casing.

The bearing piece lower surface is tightly welded with internal surface of sleeve pipe, and there is fillet in upper surface, and every group is three to four pieces.

Cleaning import is provided with above the material inlet pipeline.

Described sleeve pipe and inner pipe wall spacing are 9-15mm.

The utility model has the beneficial effects that the utility model, firstly, on the basis of original double pipe heat exchanger, In Bearing piece is housed between casing and inner tube, is easily installed, bearing area is larger, and support performance is good, it is possible to reduce produces when Flow of Goods and Materials Raw resonance, pressure resistance improve pipeline stability, and preventing casing, deformation occurs；Secondly, setting cleaning import, washing outlet, it can be with Inner tube is cleaned at any time, keeps pipeline unimpeded；Finally, inner tube and the runner tube wall that U-tube part forms are smooth, the staple fibers such as hair are difficult To be attached to tube wall adsorbent solid particle, to prevent from blocking.

Specific embodiment

The following describes the utility model in further detail with reference to the accompanying drawings.

One kind heat exchanger of material containing stereoplasm as shown in Figure 1, by cleaning import 1, material inlet pipeline 2, material inlet 3, is followed Ring water out 4, material outlet 5, washing outlet 6, circulating water intake 7, casing 8, branch pipe 9, inner tube 10, braced frame 11, bearing piece 12, U-tube part 13 forms.

Material inlet 3 connects inner tube 10 by material inlet pipeline 2, and said inner tube 10 is to be connected to be formed by more root canal roads Tube side is successively connected by U-tube part 13, and inner tube 10 and the runner tube wall that U-tube part 13 forms are smooth, plays the work of anti-blocking With material containing stereoplasm flows in inner tube 10, and clear water flows in the annular gap that inner tube 10 is formed with casing 8, with material containing stereoplasm Process forms adverse current, and logarithmic temperature difference is larger, therefore heat transfer efficiency is high, and described sleeve pipe 8 is followed with the setting of 2 junction of material inlet pipeline Ring water out 4, is equipped with cleaning import 1 above material inlet pipeline 2, every one between 10 tube wall of 8 tube wall of described sleeve pipe and inner tube Section distance three to four bearing pieces 12 of setting, it is ensured that 8 interlayer flow area of casing is annular, is provided between the every row of described sleeve pipe 8 Branch pipe 9, inner tube 10, internal circulation clear water are not provided with inside branch pipe 9, and 8 lower section side of described sleeve pipe connects material outlet 5, circulation Water inlet 7, washing outlet 6.

Material containing stereoplasm by material inlet 3 enter material inlet pipeline 2, later enter inner tube 10, flow through inner tube 10 with it is U-shaped The runner that pipe fitting 13 forms finally is discharged from material outlet 5, the ring that clear water passes through 7 sleeve pipe 8 and inner tube 10 of circulating water intake Shape gap, the flow passage formed along annular gap and branch pipe 9 carry out heat exchange, finally from recirculated water with the adverse current of material containing stereoplasm 4 discharge of outlet.When inner tube 10 needs to clean, ejected wash water enters material inlet pipeline 2 by cleaning import 1, enters inner tube later 10, the runner formed to inner tube 10 with U-tube part 13 cleans, and is finally discharged from washing outlet 6.
