Abstract
A waste steam and heat retriever of waste heat recovery equipment for paper-making industry through steaming and boiling is provided, which is a raw waste steam and heat retriever composed of a flange (1), a pipe head (2), an end plate (3), a cylinder body (5) and a grate (8) with modified internal structure. The utility model is arranged with a middle shaft (6) and laminas (7); wherein, the laminas (7) are mounted on the middle shaft (6), which are arranged from up to down in helix shape; besides, the front end of the rear lamina (7) is higher the rear end of the front lamina (7); gaps are positioned between the two laminas (7) and water form a water curtain at the gap and the water curtain sufficiently contacts with the steam, thus improves the effectiveness of regenerator; in addition, notches (4) are positioned at upper section of the cylinder body (5), so as to facilitate the clearance for dirties and the maintenance as well as the utilization.
Description
One, affiliated technical field
The utility model is in a kind of paper industry pulping by cooking technology, the papermaking digesting waste vapour waste-heat recoverer of using in the waste vapour waste heat recovery apparatus.
Two, background technology
In paper-making pulping, the general digesting technoloy that adopts, there are a large amount of steam to produce, waste heat for recovered steam, various waste vapour waste heat recovery apparatus are arranged at present, waste vapour waste-heat recoverer in these waste vapour waste heat recovery apparatus is most typical for sparge pipe adds iris type, and its major defect is: 1, sparge pipe stops up easily, and is tighter to water quality requirement; 2, the hole for water spraying on the sparge pipe is easily stopped up in fouling easily, makes the water spray poor effect at last; 3, stop up after easy-maintaining not, even can only change, improved use cost; 4, baffle design is unreasonable, and steam, water running resistance are big, and easily produces vibrations.
Three, summary of the invention
The purpose of this utility model is exactly in order to overcome above-mentioned shortcoming, and a kind of heat exchanger effectiveness height is provided, and is simple in structure, is convenient to snaking and maintenance, the papermaking digesting waste vapour waste-heat recoverer that can reduce cost.
The utility model is to realize like this, the utility model improves the internal structure of waste vapour waste-heat recoverer, in waste vapour waste-heat recoverer cylindrical shell, designed special spiral, it by be fixed on the axis blade in the shape of a spiral shape arrange and to form, and the rear end of a slice blade before the front end of back a slice blade is higher than, and be provided with the gap.Be that the utility model is made up of flange, tube head, end socket, cylindrical shell, axis, blade, double-edged fine-toothed comb etc.End socket is equipped with in the upper end of cylindrical shell, tube head is equipped with in the upper end of end socket, flange is equipped with in the upper end of tube head, double-edged fine-toothed comb is equipped with in the lower end of cylindrical shell, axis is arranged on the middle part in the cylindrical shell, blade shape is in the shape of a spiral arranged from top to bottom, is installed on the axis, and afterwards the front end of a slice blade is higher than the rear end of preceding a slice blade and is provided with the gap, and the top of cylindrical shell is provided with hand-hole.The utility model is communicated with the tube connector of waste heat recovery apparatus by flange, and the utility model is communicated with the cushion dashpot of waste heat recovery apparatus by the lower end of cylindrical shell, and former water inlet pipe is changed on the tube connector, directly is communicated with tube connector.The heat exchange water that water pump is supplied with is introduced into tube connector and steam, enter again in the cylindrical shell of the present utility model, gap between two blades forms many cascade shape moisture films, and steam flows downward along helical duct, and water is fully contacted with steam, has improved heat exchanger effectiveness, fully absorb the waste heat of steam, and hot water and steam enter the cushion dashpot of waste heat recovery apparatus through double-edged fine-toothed comb again, and steam is discharged by cushion dashpot, hot-water storage in cushion dashpot for use.When the generation fouling need be removed and keep in repair in the cylindrical shell, only need open the inlet on cylindrical shell top, operating personnel just can enter and carry out snaking, maintenance in the cylindrical shell, can prolong service life of the present utility model, save replacing number of times of the present utility model, reduced use cost.
Because the utility model improves the heat exchange structure in the cylindrical shell, the blade that is designed to be interrupted shape is in the shape of a spiral arranged, form a large amount of cascades, thereby fully absorb the waste heat in the steam, therefore, compare with former waste vapour waste-heat recoverer, have simple in structure, heat exchanger effectiveness is high, and is easy to manufacture, be convenient to the maintenance, snaking, prolong service life, reduced characteristics such as cost.

Fig. 2 is the utility model blade schematic diagram;
Fig. 3 is the A-A cutaway view of Fig. 1;
Fig. 4 is the waste heat recovery apparatus schematic diagram.
Five, specific embodiments
As shown in Figure 1, the utility model is by flange (1), tube head (2), end socket (3), cylindrical shell (5), axis (6), blade (7), double-edged fine-toothed comb compositions such as (8), end socket (3) is contained in cylindrical shell (5) upper end, being equipped with on the end socket (3) of tube head (2), flange (1) is contained in tube head (2) upper end, double-edged fine-toothed comb (8) is contained in cylindrical shell (5) lower end, axis (6) is fixed on middle part in the cylindrical shell (5), blade (3) shape is in the shape of a spiral arranged from top to bottom, be fixed on the axis (6), the rear end of a slice blade (7) before the front end of back a slice blade (7) is higher than, and be provided with the gap, the rear end upside of a slice blade (7) was (as Fig. 2 before the front end of back a slice blade (7) can be positioned at, Fig. 3), also can align with the rear end of preceding a slice blade (7), be provided with hand-hole (4) on the top of cylindrical shell (5), hand-hole (4) sealing at ordinary times is when needs carry out snaking in to cylindrical shell (5), during maintenance, can open hand-hole (4), for snaking, maintenance is used.The utility model is communicated with the tube connector (14) of waste heat recovery apparatus (see figure 4) by flange (1), and the lower end by cylindrical shell (5) is communicated with the cushion dashpot (16) of waste heat recovery apparatus.And former water inlet pipe (17) is connected by being communicated with cylindrical shell (5) to change into tube connector (14).
In pulping process, rotary spherical digester is spurting a large amount of steam that process produces, through jetting storehouse (11), tangent line pipe (12), enter vapour slurry separator (13), in vapour slurry separator (13), paper pulp in the steam is fully separated, steam after the separation enters the utility model by tube connector (14), in tube connector (14), water pump (18) is squeezed into tube connector (14) with water by water inlet pipe (17), with steam, just begin to carry out heat exchange, after entering the utility model cylindrical shell (5), owing to have under blade (7) effect of the helical arrangement of special construction, the gap between two blades (7) forms cascade, in whole cylindrical shell (5), form a lot of cascades, steam is fully contacted with water, carries out heat exchange, has greatly improved heat exchanger effectiveness.Steam and hot water see through double-edged fine-toothed comb (8) and enter cushion dashpot (16) then, and steam is discharged by cushion dashpot (16), hot-water storage in cushion dashpot (16) for use.
This shows, the utlity model has simple in structure, the heat exchanger effectiveness height, easy to manufacture, be convenient to Snaking and maintenance have prolonged service life, have reduced the characteristics such as cost. Waste heat recovery for paper industry Equipment provides a kind of novel recoverer for waste gas residual heat of paper-making digesting.
