Description
Technical field
The present invention relates to a kind of heat exchanger.
Background technology
Heat exchanger (being heat exchanger again) is widely used at many industrial circles such as weaving, chemical industry, metallurgy, pharmacy.The heat exchanger kind is a lot, and the most extensive with the dividing wall type heat exchanger application, the version of dividing wall type heat exchanger is also a lot, and tubular heat exchanger application quantity wherein ranks first.
In tubular heat exchanger, two significant components are heat exchanger tube and tube sheet, and the heat exchanger tube surface is very easy to accumulate impurity such as mud, incrustation scale, greasy dirt, if untimely the cleaning out of these impurity can cause heat exchange to reduce, and then increase energy consumption.Need regularly to clean to heat exchanger, heat exchanger cleaning amount is bigger, for this reason for this reason; Had and developed heat exchanger with cleaning function; See that the patent No. is the Chinese utility model patent " heat exchanger with cleaning device " (Granted publication number for CN2656923Y) of ZL03209427.2, this patent has been set up driver and brush body in heat exchanger, driver drives brush body work during cleaning; Accomplish cleaning, similarly can also be with reference to CN2903891Y.But the heat exchanger of above-mentioned cleaning function, complex structure, cleaning performance are not good, need to improve.
In addition, mix for not making two kinds of fluids, heat exchanger tube must closely be connected with tube sheet.Heat exchanger tube has three kinds with the syndeton commonly used of tube sheet in the metal switching heat-exchanger: welding, expanded joint and expanded and welded tube joint are connected.It is behind expanded joint, to weld a circle at the pipe outward flange again that expanded and welded tube joint connects, to strengthen bonding strength.
Above-mentioned connected mode existence is following not enough: the fixing position of heat exchanger tube and tube sheet is become flexible easily and is produced trickle gap, makes the leak of liquid in the heat exchanger.Welding brings and receives stress influence, easily at the weld cracking, causes the simplified interior leak of liquid of heat exchanger.Simultaneously said method all take a lot of work, time-consuming, and need special equipment, power consumption increases processing cost.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of convenience for washing to have the heat exchanger of cleaning function efficiently to the above-mentioned state of the art.
Another technical problem to be solved by this invention provides the good heat exchanger with cleaning function of a kind of cleaning performance.
Another technical problem to be solved by this invention provides a kind of tube sheet and the heat exchanger tube heat exchanger that has cleaning function efficiently easy to assembly.
The present invention solves the problems of the technologies described above the technical scheme that is adopted: a kind of heat exchanger with cleaning function is characterized in that comprising
Heat exchanger body comprises the tube sheet of vertical setting and is horizontally set at a plurality of heat exchanger tubes in the tube sheet installing hole that the bottom has waste liquid outlet, and the top has a plurality of cleansing medium imports;
Drip tube or sparge pipe, liquid feeding end are provided with cleansing medium valve and cleaning agent valve, and outlet end is communicated with aforesaid cleansing medium import; And
Oily-water seperating equipment has waste liquid import, waste oil outlet and wastewater outlet, and aforesaid waste liquid import is connected with the waste liquid outlet of heat exchanger body.
For realizing Electronic Control, described cleansing medium valve and cleaning agent valve are magnetic valve.Can certainly manual adjustments, but be preferred with the magnetic valve.
For making the assembling of tube sheet and heat exchanger tube efficient and convenient, at least one end of described heat exchanger tube has radially outward protruding limiting section, and said heat exchanger tube is positioned at the limiting section fore-end and inserts installing hole, and aforesaid limiting section is limited in the madial wall of tube sheet.
Further, described limiting section in the form of a ring and with tube sheet madial wall tight fit.
Further, described tube sheet is two and is located at the heat exchanger tube two ends respectively that accordingly, described limiting section then takes shape in the heat exchanger tube two ends.
Further, be provided with sealing ring or fluid sealant in the described installing hole.
As preferably, described heat exchanger body has last warming plate and following warming plate, and aforesaid going up on the warming plate is located in described cleansing medium import, and described waste liquid outlet then is located on the aforesaid following warming plate.
Compared with prior art, the invention has the advantages that: convenience for washing is quick, and scavenging period is shorter, does not influence normal heat exchange work basically.Overall structure is simple, and cooperation can be removed the cleaning agent of greasy dirt, and cleaning performance is comparatively desirable.

The specific embodiment
Embodiment describes in further detail the present invention below in conjunction with accompanying drawing.
As shown in Figure 1; Heat exchanger 101 in the present embodiment is applied on the forming machine baking oven 100; Hot gas in the flue gas leading 7 pass through primary purifying device 4, heat exchanger 101, second cleaner 5 successively, discharge from delivery pipe 6 at last, and the waste gas that produces in the cloth type-approval process is like this discharged after through heat exchange; Most of heat recovery and utilization, energy consumption reduces.
As shown in Figure 2, heat exchanger 101 comprises heat exchanger body 10, sparge pipe 3 and oily-water seperating equipment.
Like Fig. 3 and shown in Figure 4; Heat exchanger body 10 comprises two tube sheet 1a of warming plate 3a, warming plate 4a, vertically setting down and is horizontally set at a plurality of heat exchanger tube 2a in the tube sheet 1a installing hole; In conjunction with Fig. 5, Fig. 6 and shown in Figure 7, heat exchanger tube 2a two ends have radially outward protruding limiting section 21a, and; Heat exchanger tube 2a is positioned at limiting section 21a fore-end and inserts installing hole, and limiting section 21a is limited in the madial wall of tube sheet 2a.Limiting section 21a in the form of a ring and with tube sheet 2a madial wall tight fit.Can be provided with sealing ring or fluid sealant in the installing hole, further play sealing function.Last warming plate 3a is provided with cleansing medium import 31a, and following warming plate 4a is provided with waste liquid outlet 41a.
