Abstract
The invention provides a solar sewage treatment device, relating to the field of sewage treatment, especially the field of sewage treatment based on energy of collected sunlight. With the increase of municipal sewage, a sewage treatment plant needs to consume a large amount of electric energy, biological technologies and chemicals. In order to fully utilize energy of sunlight, the energy of sunlight is used for sewage treatment. According to technical scheme, the solar sewage treatment device comprises a sewage tank and a sewage treatment tank, wherein the sewage tank and the sewage treatmenttank are connected by a water pipe; the sewage treatment tank is divided into three region by partitions; the bottom of each partition is provided with a through hole; one of the three regions receives a light band collected by a biprism, and the other two regions are pretreatment tanks; water is gasified under the irradiation of the light collected by the biprism, and then rises and enters a gaschamber; and the gas chamber is connected to a water outlet pipe through a plastic pipe. The invention has the following beneficial effects: the energy is saved; purer water can be obtained from sewage; through preheating pretreatment, part of organic substances are previously gasified; and after the water is gasified, most of the energy is returned to sewage through the water outlet pipe, thereby improving the utilization efficiency of the energy.
Description
Technical field
The present invention relates to sewage treatment area, the energy that particularly compiles sunlight carries out sewage disposal.
Background technology
Municipal effluent is more and more, and environmental pollution is more and more serious, and people more and more need sewage is carried out harmless treatment.
Present sewage work need expend a large amount of electric energy, biotechnology and pharmaceutical chemicals, also needs a large amount of electric energy and produce pharmaceutical chemicals, and produces environmental pollution.
Summary of the invention
The objective of the invention is to take full advantage of solar energy, solar energy is used for sewage disposal.
The present invention realizes that the technical scheme that goal of the invention adopts is:
Because the sun is mobile, the luminous point that convex lens converge can be moved, and along with the movement of the sun, no longer is normal incidence, luminous point also can disperse, if convex lens are changed into bevelled mirror, the rib of bevelled mirror and the travel direction of the sun are consistent, then sunlight will converge on the light belt of straight line, common bevelled mirror will expend a large amount of light transmissive materials, therefore the cost of manufacture height reduces triple-prism height, and this moment, bevelled mirror just became biprism.
Biprism is a bevelled mirror that elongates and flatten in fact, thinner thickness, and sunlight is close to shining abreast on the biprism, because wavelength is not unique, the light of different wave length can not be pooled to a bit, so sunlight pools a light belt to the center, and energy will strengthen widely.
Therefore, if if the width of biprism can reach more than 1 meter, if the light belt that converges shines one close to the environment of sealing, temperature will reach naturally than higher, if shine the water body of sealing, will cause the vaporization gradually of water.
A sewage lagoon and a treatment tank, sewage lagoon has a water pipe to be connected with treatment tank; Treatment tank is divided into 3 subregions by dividing plate, and the dividing plate bottom has through hole, through hole to have rising pipe to pass through, and flows at each subregion for sewage in the slit between through hole and the rising pipe; Wherein lattice are accepted the light belt that converges of biprism, be called the illumination pond, other two lattice are pretreatment pool, the rib of biprism is parallel with the path of sun operation, the length direction for the treatment of tank is parallel with the rib of biprism, biprism compile irradiate light to the central authorities in illumination pond, rise after the water vapor, enter air chamber, air chamber is connected to rising pipe by plastics tubing, rising pipe is laid in the through hole of bottom for the treatment of tank, the tube wall of gas by rising pipe be the water of heat transferred treatment tank, and the water for the treatment of tank is heated, and liquefaction of gases is water, when flowing through pretreatment pool, further dump energy is passed to sewage, make sewage carry out thermal pretreatment, after the thermal pretreatment temperature raises, will make the partial organic substances vaporization, vaporization is discharged by tracheae, and the gas of tracheae can be concentrated afterfire.
Treatment tank adopts the relatively poor material of heat conductivility to make, and the upper surface in illumination pond is transparent material.
The diameter of rising pipe is 1mm, and thickness of pipe 0.1-0.2mm adopts corrosion resistant metal or plastics.
The invention has the beneficial effects as follows: utilize the sun power that converges, directly be converted to heat energy, do not need extra energy support, energy-conservation; Utilize specific heat of water bigger, sewage by converging solar heating to vaporization, is obtained purer water from sewage; Utilize the lower characteristics of vaporization temperature of organic gas, through thermal pretreatment, this part material is vaporized in advance, harmless treatment is carried out in concentrated combustion then; Moisture vaporization back is given back sewage by rising pipe with most of energy, improves the utilising efficiency of energy; For rhizoma sparganic, thin thickness, focal length is long, and economical with materials can be done widelyer, can converge more sun power.

Embodiment
Biprism 1 is a bevelled mirror that elongates and flatten in fact, thinner thickness, and sunlight is close to shining abreast on the biprism 1, because wavelength is not unique, the light of different wave length can not be pooled to a bit, so sunlight pools a light belt to the center, and energy will strengthen widely.
Experiment confirm is arranged: the convex lens of a diameter 10cm, at the Chengdu sunlight in October, converge on the point of diameter 3mm, do not have around under the situation of thermoshield, the temperature of convergent point can reach more than 260 degrees centigrade.At middle school physics a lecture experiment is arranged, convex lens optically focused is lighted the scraps of paper, and this experiment has illustrated that also temperature can reach more than 150 degrees centigrade.
Therefore, if if the width of biprism can reach more than 1 meter, if the light belt that converges shines an environment that approaches sealing, temperature will reach naturally than higher, if shine the water body of sealing, will cause the vaporization gradually of water.
A sewage lagoon 2 and a treatment tank, sewage lagoon 2 has a water pipe 3 to be connected with treatment tank; Treatment tank is divided into 3 lattice by dividing plate, through hole is arranged at the dividing plate bottom, wherein lattice are accepted the light belt that converges of biprism 1, be called illumination pond 7, other two lattice are pretreatment pool 6, the rib of biprism is parallel with the path of sun operation, the length direction for the treatment of tank is parallel with the rib of biprism 1, biprism compile the central authorities that light belt shines illumination pond 7, rise after the water vapor, enter air chamber 9, air chamber 9 is connected to rising pipe 4 by plastics tubing 8, rising pipe 4 is laid in the bottom through-hole for the treatment of tank, the tube wall of gas by rising pipe 4 be the water of heat transferred treatment tank, and the water for the treatment of tank is heated, and liquefaction of gases is water, when flowing through pretreatment pool 6, further dump energy is passed to sewage, sewage is carried out thermal pretreatment, after the thermal pretreatment temperature raises, will make the partial organic substances vaporization, vaporization is discharged by tracheae 5, and the gas of tracheae 5 can be concentrated afterfire.
