Summary of the invention
The utility model overcomes the deficiency of prior art; A kind of corrosion-resistant shell and tube evaporator is provided; The design of material, structure and condenser length through the exchange heat pipe; Reach corrosion resistance and good, heatproof is high, heat conduction strong, the convenient cleaning and the advantage of maintenance, is particularly suitable for freezing with the liquid of corrosion property.
The technical scheme of the utility model is following: corrosion-resistant shell and tube evaporator; Structure is made up of U-shaped titanium pipe, PVC-U pull bar, PVC-U shell, composite ti pipe plate, support foot rest, choke block, cold-producing medium import and export etc., parallel the placing in the evaporimeter of said U-shaped titanium pipe, and its two mouth of pipe is imported and exported with cold-producing medium respectively and is linked to each other; The composite ti pipe plate vertically is positioned at U-shaped titanium nozzle position; Said PVC-U pull bar is parallel to be installed on the line of symmetry of U-shaped titanium pipe, is 90 ° of angles with each choke block, and the PVC-U shell is positioned at outermost layer; Surround U-shaped titanium pipe, support foot rest is installed on the lowermost end of evaporimeter.
Said composite ti pipe plate is connected with the titanium pipe with the titanium weldering; One side plates the epoxy resin diaphragm therein, and the liquid that is used in cold-producing medium and the shell carries out heat exchange, can guarantee the isolation of cold-producing medium and water system; The interior cross aluminium section bar of inserting improves refrigeration heat exchange effect, further strengthens erosion-resisting performance.
Said titanium pipe is the heat exchanger tube that titanium alloy is made, and is the design of " U " shape, and " U " type pipe evaporator is equipped with core body, the convenient cleaning and maintenance.
Said PVC-U pull bar is fixed on the last a slice on the choke block with the string that is connected of composite ti pipe plate, prevents that current are with choke block detrusion position.
Said refrigerant inlet is welded on the shrouding; One of copper pipe is connected with the liquid pipe, and said refrigerant outlet is welded on the shrouding, and one of copper pipe is connected with muffler; Said shrouding adopts steel plate materials to use bolt, prevents that further cold-producing medium and the fluid that is frozen from leaking.
Said choke block adopts the PVC-U material, but blocking water flow improves water flow velocity, strengthens the heat exchange effect.
Said support foot rest adopts the channel-section steel material, playing a supportive role of complete machine, is prone to move, conveniently fixes and on-the-spot flexibly installation.
According to the utility model, also be provided with an anti-icing switch, survey the temperature of Inlet and outlet water, thereby to the flow and the start-stop of signal system control water pump, it is stifled that the temperature that prevents water in the shell is crossed low and icing generation ice.
According to the utility model, also be provided with a PVC-U flange, connect water inlet pipe and water outlet pipe, convenient on-the-spot connection, readily removable; Design discharges water and sewage draining exit, adopts complete interior tooth PVC band to stop up, and is used for cleaning and discharging water.
The attainable beneficial effect of the utility model is: heat exchanger tube adopts the titanium alloy manufacturing, corrosion resistance and good, and heatproof is high, adopts the design of " U " shape simultaneously, the convenient cleaning and maintenance; Can be used for the big heat exchange occasion of the temperature difference according to the length of condenser length adjustment evaporimeter; While is in light weight, pollution-free, floor space is little, and it is freezing to be suitable for seawater, fields such as chemical plant spent hot water's heat pump energy recovery.
Description of drawings
Fig. 1 is the agent structure sketch map of the utility model, and wherein 1 is the PVC-U shell, and 2 is zinc-plated full tooth screw rod, and 3 is support foot rest; 4 for discharging water and sewage draining exit, and 5 is the PVC-U flange, and 6 is anti-icing switch; 7 is the composite ti pipe plate, and 8 is U-shaped titanium pipe, and 9 is choke block; 10 is refrigerant outlet, and 11 is refrigerant inlet, and 12 is the PVC-U pull bar.
The specific embodiment
Be described further below in conjunction with the specific embodiment of accompanying drawing the utility model.
As shown in Figure 1, corrosion-resistant shell and tube evaporator, U-shaped titanium pipe (8) is parallel to be placed in the evaporimeter; Its two mouth of pipe links to each other with outlet (10) with refrigerant inlet (11) respectively; Composite ti pipe plate (7) vertically is positioned at U-shaped titanium nozzle position, and said PVC-U pull bar (12) is parallel to be installed on the line of symmetry of U-shaped titanium pipe (8), is 90 ° of angles with each choke block (9); PVC-U shell (1) is positioned at outermost layer; Surround U-shaped titanium pipe, support foot rest (3) is installed on the lowermost end of evaporimeter, and center bottom is installed one and discharged water and sewage draining exit (4).
