Technical field
The utility model relates to the tanning sewage treatment facility, particularly is applicable to the tanning sewage high-temperature sterilization stove of middle-size and small-size leather-making enterprises.
Background technology
At present, China's leather industry is doted on big waste removal equipment and is disposed of sewage the equipment except that large-scale tannery has, and general medium and small sized enterprises are because factor incompetences such as funds difficulty and place are built extensive sewage disposal facility.Tannery gives off the sewage that contains the heavy metal harmful element in a large number in producing, and the past all is directly to be discharged in the rivers, poisons environment, influences groundwater resource, causes the very big harm to environment.Pollution in leather industry rots to produce pungent gas to atmospheric pollution mainly due to grease, and various chemical feedstockss such as soda ash, Sodium Sulphide, liming, ammonium chloride, sulfuric acid, salt, chromium powder etc. are to soil and contaminated water source.Therefore, design be fit to middle-size and small-size leather-making enterprises comprehensive to sewage disposal economical again efficiently equipment be the task of top priority.
The utility model content
The purpose of this utility model is at above-mentioned defective, and a kind of tanning sewage high-temperature sterilization stove that is applied in the medium and small sized enterprises is provided.Further improve processing efficiency, structure is more reasonable.
The technical solution of the utility model is a tanning sewage high-temperature sterilization stove, comprise upper furnace body (1), lower furnace body (2), distilled water outlet (3), distilled water collector groove (4), sewage import (5), base (6), well heater (7) and water outlet (8), upper furnace body (1) is that branch body structure and sealing flexibly connect with lower furnace body (2), it is characterized in that:
A, said base (6) are the terraced steps structures, locate to be provided with the highest step of the first step near sewage import (5), and second stage step is lower than first step step, and well heater (7) is installed on the step of the second stage;
B, said water outlet (8) are arranged on the lower end part of sewage import (5); Sewage import (5) is provided with bend and is communicated with lower furnace body (2) before first step step in base (6), be provided with reflux hole (9) at the step lower inclined plane place, the second stage of base (6) and be communicated with base (6) lower cavity;
C, said well heater (7) are made up of retaining plate (7-1), electrothermal tube (7-2), fixed support sheet (7-4), shell (7-5), electrothermal tube (7-2) is installed on several fixed support sheets (7-4), fixed support sheet (7-4) is installed on the shell (7-5), and shell (7-5) is tightly connected with retaining plate (7-1).
Electrothermal tube (7-2) in the said well heater (7) is the stainless steel electrothermal tube, and electrothermal tube (7-2) exposes the outer area of shell (7-5) and accounts for 1/5 of pipe area, and shell (7-5) is that a sealing is box-like.
Several open holess (7-3) are arranged on the said retaining plate (7-1).
The utility model has the advantages that base (6) is designed to terraced steps, make sewage evenly flow through well heater (7) thermally equivalent and evenly sterilize; Electrothermal tube (7-2) has fixed support sheet (7-4) to support and the peripheral enclosed construction of keeping at a distance plays the protection thermal source and keeps electrothermal tube high temperature, effluent stream cross the high-temperature zone wherein bacterium killed by high temperature, play the quick sterilization effect; Also sewage is heated simultaneously, make the various chemical ingredients generation neutralizing effects in the sewage, the impurity in the sewage is separated with the moisture generation, the water after the neutralization is discharged into pond for recovering precipitation, the middle recycle of again water in the pond being put into production; It is also recycling that the gas that produces in the high-temperature sterilization condenses into distilled water; Improve sterilising effect, structure is more reasonable.
Description of drawings
Fig. 1 is a structural representation of the present utility model.Fig. 2 is the left side view of well heater, and Fig. 3 is the structural representation of well heater.
Embodiment
Further specify embodiment below in conjunction with accompanying drawing.
With reference to Fig. 1, Fig. 2, Fig. 3.1-upper furnace body, 2-lower furnace body, 3-distilled water outlet, 4-distilled water collector groove, 5-water-in, 6-base, 7-well heater, 8-water outlet, 9-reflux hole, 7-1 retaining plate, 7-2 electrothermal tube, 7-3 open holes, 7-4 fixed support sheet, 7-5 shell.As shown, upper furnace body (1) is that the branch body structure seals flexible connection again with lower furnace body (2), on upper furnace body (1) inner side-wall distilled water collector groove (4) is set, the outside is equipped with distilled water outlet (3) upper furnace body (1) top and makes wedge angle or sharp cone distal, and just upper furnace body (1) is made cuboid or round shape with lower furnace body (2).The last side of lower furnace body (2) is equipped with sewage import (5), the band valve.Base on the furnace bottom (6) is made terraced steps, locates to be provided with the highest step of the first step near sewage import (5), and second stage step is lower than first step step, and well heater (7) is installed on the step of the second stage.Doing like this is to make sewage evenly flow through well heater, thermally equivalent, evenly sterilization.Well heater (7) is made by retaining plate (7-1), electrothermal tube (7-2), fixed support sheet (7-4), shell (7-5) and is formed, electrothermal tube (7-2) is installed on several fixed support sheets (7-4), fixed support sheet (7-4) is installed on the shell (7-5), and shell (7-5) is tightly connected with retaining plate (7-1).Electrothermal tube (7-2) is the stainless steel electrothermal tube, nichrome wire is equipped with in the inside, silica powder is housed around it, electrothermal tube (7-2) exposes the outer area of shell (7-5) and accounts for 1/5 of pipe area, do like this is in order to reduce the consumption of heat as far as possible, make sewage once contact high temperature hot-zone by quick kill bacteria, and sewage can not absorb more heat.Electrothermal tube (7-2) and fixed support sheet (7-4) periphery are made closed, thereby shell (7-5) is a sealed box shape.For retaining plate (7-1) can be installed on the shell (7-5) well, then several open holess (7-3) are set at retaining plate (7-1).Water outlet (8) is arranged on the lower end part of sewage import (5), and by-pass valve control is housed, and the wastewater level that has heated is controlled at can expire the bend pipe of sewage import (5).For sewage heating back energy is made full use of, sewage import (5) is provided with bend and is communicated with lower furnace body (2) before first step step in base (6), be provided with reflux hole (9) at the step lower inclined plane place, the second stage of base (6) and be communicated with cavity under the base (6).Make sewage after the heating be used for the sewage of preheating inlet like this, make full use of heat energy.Sewage various chemical ingredientss in heat-processed can produce neutralizing effect, and impurity is separated with moisture, and moisture is discharged into the pond for recovering precipitation, then impurity is carried out harmless treatment, and moisture is then recycling, the middle recycle of putting into production.The gas that produces in the high-temperature sterilization condenses into distilled water and can be recycled in the furnace wall.The utility model is a device in the pipeline processes sewage equipment.
