Description

  The present invention relates to a sludge used for treating sludge such as wastewater sludge and food sludge, a food residue, and a shock wave drying apparatus for treating liquid waste liquid.

In order to solidify the sludge, when the sludge is stirred and mixed with the solidifying agent, the water content of the sludge is lowered and the handling is improved.
In recent years, organic sludge such as wastewater sludge and food sludge from food factories has been dehydrated, dried and then pulverized, and this dry powder is mixed into biodegradable seeding sheets and garbage bags. By doing so, it is proposed to reuse as fertilizer.

  To make slurry raw sludge and food residue and liquid waste liquid into powdery dry matter, first mix solidification agent with raw sludge in sludge treatment equipment, and further blow carbon dioxide to reduce the moisture of raw sludge. After removing as much as possible, this sludge is sun-dried or machine-dried, and the dried and solidified sludge is pulverized into a powdery dried product.

  However, in such treatment, it takes a certain amount of time after stirring and mixing with the solidifying agent until the moisture content of the sludge becomes sufficiently low, and this is one factor that hinders the improvement of sludge treatment efficiency. ing.

In addition, it takes a lot of time to sufficiently dry the sludge / slurry liquid material from which moisture has been removed by the sludge treatment apparatus by sun drying or mechanical drying.
And until the sun-dried or machine-dried dried product is solidified, it takes time to pulverize with a pulverizer to a sufficiently small particle size that can be used in a garbage bag.

  Many such problems have been solved in Japanese Patent Application Laid-Open No. 2004-74143, and sludge can be treated efficiently.

Problems that the device tries to solve

  In this way, many of the problems can be solved in Japanese Patent Application Laid-Open No. 2004-74143. However, in the sludge treatment method and the sludge treatment apparatus disclosed in Japanese Patent Application Laid-Open No. 2004-74143, pulverization is performed. The steam supplied to the drying unit is blown in a tangential direction into the inside of the pulverization drying unit forming a cylinder, swirls in the pulverization drying unit, collides with the sent sludge, and pulverizes and drys the sludge. I have to.

  In particular, pulverization and drying of processed products in a sludge treatment plant is performed by a blower, a heater, and a hot air conveyance type dryer, and the hot air conveyance type dryer is erected as an annular main body, in which dehydration treatment is performed. An annular airflow drying passage for circulating the product and air is provided, and an inlet for introducing the dehydrated material into the airflow drying passage, a supply port for introducing high-temperature / high-speed air, A discharge port is provided for discharging the dried product with air from the airflow drying passage.

  The treated product is introduced into the airflow drying passage of the main body from the inlet, blown away by the high-temperature / high-speed air introduced from the supply port, pulverized and dried, and the sludge particles pulverized and dried to a certain particle size below Although it is discharged to the outside together with air from the discharge port by suction by a device (blower acting through the first bag filter in Japanese Patent Application Laid-Open No. 2004-74143), insufficient sludge particles have a particle size of a certain degree or less. It circulates in the air-drying passage.

  For this reason, the flow of high-temperature and high-speed air circulating in the air-drying passage becomes a linear laminar flow, and the processed material is pulverized and dried along the laminar flow of linear high-temperature and high-speed air that circulates. It is very inconvenient to use the hot-air transport type dryer because the damage of the air becomes non-uniform and the generation of wear is easy, and the hot-air transport type dryer has low destruction, pulverization, dispersion force (hereinafter referred to as pulverization force) and low drying capacity. I felt.

Means for solving the problem

  The present invention eliminates these inconveniences, pressurizes before jetting into the airflow drying passage, turns the flow of high-temperature, high-speed air circulating in the airflow drying passage into a spiral turbulent flow, crushing power and drying capacity It is intended to provide a shock wave drying apparatus for treating sludge and food residue and liquid waste liquid that can improve the efficiency and efficiently pulverize and dry the processed material.

  Formed as a quadrangular ring in the tubular body, a charging port is provided on one side outer periphery of the passage main body to circulate the dehydrated processed product and air. A discharge hole is provided at the upper part of the inner periphery of the side to project a dry product that has been pulverized and dried in powder form together with air from the passage body. The tube cylinder of the passage body to be erected and the center of the jet outlet are pierced by shifting one side so that the center is not the same on the vertical plane, and one end of the tube body is expanded in a trumpet shape and used as a receiving part A turbulent flow plate with a receiving part at the injection port side and a cylindrical body with a spiral on the inner periphery of the tip and one on the inner periphery and the other projecting along the spiral The ejection cylinders projecting at several locations are inserted into the receiving cylinder so as to be detachable, and the partition plate is inclined to the outside of the inner periphery of the passage main body along the circulation. It is possible to introduce high-temperature and high-speed air by providing a supply port on one side of a box-shaped box body that is provided in multiple places to serve as a drying passage, and has an upper surface opened and narrowed from the input port provided on one side. The pressure box is provided below the drying passage so that the supply port is on the inlet side to cover the ejection cylinder and keep airtight.

  In use, when high-temperature / high-speed air supply starts, when high-temperature / high-speed air is supplied into the box body of the pressurized box from the supply port, the box body becomes thinner as it goes to the other side from the supply port side. Because of its shape, it is pressurized during circulation in the box body and becomes hotter and faster air.

  When pressurized and heated to a higher temperature and higher speed, the air is continuously supplied one after another. In this case, too, high-temperature and high-speed air passes through the jet cylinder while being pressurized, and finally hits the turbulent flow plate to form a spiral turbulent flow from the jet cylinder of the jet outlet into the passage main body. It is ejected as ultra-high speed, high-speed air.

In this way, ultra-high-speed high-temperature / high-speed air is ejected into the passage body, and the tube core of the passage body to be installed and the tube core of the ejection cylinder are shifted to one side so as not to be on the same vertical plane, The high-temperature and high-speed air jetted into the passage main body does not jet into the central portion of the pipe body of the passage main body, but becomes a spiral turbulent flow along the circumference of the pipe body.
In this way, turbulent flow in two stages, turbulent flow in the turbulent plate and turbulent flow due to the deviation of the jet outlet, ensures that high-temperature and high-speed air is always in a turbulent state throughout the passage body. It is circulating.

  Furthermore, centrifugal force is generated when turbulent high-temperature, high-speed air circulates in the passage body, and the centrifugal force prevents it from shifting to the outside, preventing wear on the outer peripheral surface of the passage body and preventing turbulence. High temperature and high speed air can be circulated with good flow.

  And when high-temperature and high-speed air starts to circulate in the passage body while turbulent, the dehydrated material is continuously introduced into the passage body from the inlet, and it is not biased by the high-temperature and high-speed air that circulates in turbulent flow. The dehydration agent that was blown away in the passage body and crushed and dried rapidly, and the large sludge particles turned into small sludge particles and the water contained in the inside evaporated rapidly, and did not react in the pretreatment. In addition to promoting dehydration by reaction, pulverization and drying are sufficiently performed due to turbulent flow to improve the pulverization and drying ability, and pulverization and drying can be performed in a short time.

In this way, processed particles that have been pulverized and dried to a particle size of a certain degree or less are discharged to the outside from the discharge port by air by suction by another device, and processed particles having a relatively large particle size that are not yet sufficiently pulverized and dried. Is not discharged from the discharge port, is circulated through the passage body again, and is repeatedly pulverized and dried until it reaches a certain particle size, and then discharged from the discharge port.
In addition, you may make it abolish the receiving part of a receiving cylinder and to provide a receiving part in an ejection cylinder.
Further, the cross section of the turbulent flow plate is not limited to a quadrangle, and a triangular or trapezoidal shape may be provided and the side surface may be inclined.

Effect of device

  As described above, since the high temperature and high speed air supplied to the turbulent flow plate provided in the ejection cylinder hits and is ejected into the passage body as a spiral turbulent flow, In addition to being able to circulate in the passage body by turbulent flow without becoming a laminar flow, it is possible to prepare various types of ejection cylinders with different inner diameters by making the ejection cylinder detachable, and the situation of the processed material to be processed It is possible to select an optimal ejection cylinder according to the situation.

  According to a second aspect of the present invention, when high-temperature and high-speed air turbulent in the passage main body is ejected from the ejection cylinder, the jet does not flow into the central portion of the pipe body of the passage main body but is jetted along the peripheral surface of the pipe body due to the deviation of the ejection cylinder. Therefore, it becomes a spiral turbulent flow again, and the turbulent flow can be reliably maintained and circulated by a synergistic effect with the turbulent plate.

  According to the third aspect of the present invention, since the box main body is narrowed toward the other side, the high temperature / high speed air supplied into the box is pressurized while flowing in the box main body to become higher temperature / high speed air. .

  According to a fourth aspect of the present invention, a wide range of pressurized high-temperature and high-speed air is received at the receiving portion of the receiving cylinder and is sent into the injection cylinder inserted into the receiving cylinder, so that the injection cylinder is pressed while pressurizing the high-temperature and high-speed air again. The inside can be ejected into the passage body.

  According to a fifth aspect of the present invention, the partition plate is provided outside the passage main body to prevent the high-speed and high-speed air turbulent in the passage main body from being displaced to the outside due to the centrifugal force generated. It is possible to improve the flow of high-temperature and high-speed air that prevents turbulent flow and prevents wear on the outer peripheral surface.

  In this way, two-stage turbulence and two-stage pressurization enhance the supplied high-temperature and high-speed air, circulate in the passage main body as a powerful high-temperature and high-speed turbulence, and the dewatered Because it blows away the processed material by the impact of turbulent flow, it has a number of features such as improving sludge crushing / drying capability reliably and efficiently performing crushing / drying processing in a short time. is there.

  Formed as a quadrangular ring in the tubular body, a charging port is provided on one side outer periphery of the passage main body to circulate the dehydrated processed product and air. A discharge hole is provided at the upper part of the inner periphery of the side to project a dry product that has been pulverized and dried in powder form together with air from the passage body. The vertical pipe core of the passage body to be erected and the center of the jet outlet are pierced to one side so that they are not the same on the vertical plane. There are several turbulent flow plates along the helix that protrude at the outlet with the receiving part on the inlet side, spiral in the inner periphery of the tip, and one is flush with the inner periphery and the other protrudes The ejection cylinder projecting on the pipe is inserted into the receiving cylinder so as to be detachable, and the partition plate is inclined outside the inner periphery of the passage body so as to follow the circulation. It is provided at a location as a drying passageway, and a supply port is provided on one side of a box-shaped box body that is open as the top surface and narrows from the input port provided on one side, allowing high-temperature and high-speed air to be introduced. A pressurizing box is provided below the drying passage so that the supply port is on the inlet side to cover the ejection cylinder and keep airtight.

  In the figure, reference numeral 1 denotes an entire hot-air conveying type drying apparatus comprising a drying passage 2 and a pressurizing box 3, and reference numeral 2 denotes a drying passage. An inlet 5 is provided on the outer periphery of one side of the passage main body 4 that circulates the air and air. The inlet 5 is provided in the upper portion of the inner periphery of the one side. A discharge port 6 for discharging dried dry matter together with air from the passage body 4 protrudes with the other end facing upward, and a jet port 7 for ejecting turbulent flow to the lower outer periphery is provided with more turbulent flow. In order to make it easy to occur, the pipe vertical core W of the passage main body 4 and the center X of the jet outlet 7 which are erected are formed at four positions with a shift of one dimension so as not to be the same on the vertical plane.

  Reference numeral 8 is a cylinder that is a cylinder and has one end widened in a trumpet shape as a receiving portion 9. The receiving portion 9 is placed on the inlet 5 side at the four outlets 7, and at one location close to the inlet 5. The remaining three locations parallel to the insertion port 5 are projected so as to be inclined toward the insertion port 5, and the pipe vertical core W of the passage body 4 and the pipe core Y of the receiving cylinder 8 are erected. The shift dimension is shifted by 1 on one side so as not to be the same on the vertical plane.

  Reference numeral 10 denotes a jet cylinder in which a turbulent flow plate 11 which is formed in a cylindrical shape and spirals on the inner periphery of the tip and one of which faces the inner periphery and the other protrudes is provided at two locations along the spiral. The pipe core W of the passage body 4 and the pipe core Z of the jet cylinder 10 (the pipe core Y of the receiver cylinder 8 and the pipe core Z of the jet cylinder 10 are the same pipe). Are offset by one to prevent them from being the same on the vertical plane.

  3 is a supply port 16 provided on one side 14 of a box-shaped box body 15 which has an upper surface opened and a bottom surface 13 is inclined upwardly toward the other side 12 and becomes thinner from one side 14 toward the other side 12. Is a pressurizing box that enables introduction of high-temperature and high-speed air, and is provided below the drying passage 2 so that the supply port 16 faces the input port 5 and covers the ejection cylinder 10 so as to keep airtightness.

Reference numeral 17 denotes a partition plate, which is provided at eight locations on the inner periphery outside of the annular curved portion M formed by the passage body 4 so as to be inclined along the flow.
In addition, although the case where the turbulent flow plate 11 is provided in two places is described, it is not necessarily limited to two places, and increases or decreases as necessary.
Moreover, although the case where the partition plate 17 is provided in eight places on the inner periphery outer side of the curved part M is demonstrated, it does not necessarily limit to the curved part M and eight places, and increases / decreases as needed.

In use, when the supply of high-temperature and high-speed air is started, the high-temperature and high-speed air is supplied into the box body 15 of the pressurization box 3 from the supply port 16.
The high-temperature and high-speed air supplied into the box body 15 is compressed while being circulated through the box body 15 because the box body 15 becomes thinner from the supply port 16 side toward the other side surface 12. It becomes high temperature and high speed air.

  When the air is pressurized and becomes higher temperature / high speed air, it is continuously supplied one after another, so that a wide range of high temperature / high speed air is received by the receiving portion 9 and flows into the ejection cylinder 10. The high-speed air passes through the ejection cylinder 10 while being pressurized, hits the turbulent flow plate 11 to become a spiral turbulent flow, and rapidly exceeds the ejection outlet 7 ejection cylinder 10 into the passage body 4 of the drying passage 2. It is ejected as high-speed high-temperature and high-speed air.

Then, high-temperature and high-speed air is jetted into the passage main body 4, and the vertical displacement W of the passage main body 4 and the tubular core Z of the ejection cylinder 10 which are erected are shifted by one dimension. Therefore, the high-temperature / high-speed air ejected into the passage main body 4 does not jet into the central portion of the pipe body of the passage main body 4 but becomes a spiral turbulent flow along the circumference of the pipe body.
In this way, the turbulent flow in the two-stage structure of the turbulent flow due to the turbulent flow in the turbulent flow plate 11 and the turbulent flow due to the deviation size 1 of the ejection port 7 is always in a turbulent state all the way inside the passage body 4. However, high-temperature and high-speed air is circulating.

  Furthermore, centrifugal force is generated when turbulent high-temperature and high-speed air circulates in the passage main body 4, and it is prevented from being displaced to the outside by the centrifugal force, and the outer peripheral surface of the inner periphery of the passage main body 4 is prevented from being worn, It can circulate turbulent high temperature and high speed air with good flow.

  Thus, when high temperature and high speed air starts to circulate in the passage main body 4 while turbulent, the dehydrated material is continuously fed into the passage main body 4 from the inlet 5, and the high temperature Without being biased by high-speed air, it is blown away uniformly in the passage body 4 and rapidly pulverized and dried. Large treated particles become small treated particles and the water contained therein is rapidly evaporated. It reacts with the unreacted dehydrating agent to promote dehydration, and because of turbulent flow, pulverization and drying are sufficiently performed to improve pulverization and drying capability, and pulverization and drying can be performed in a short time. .

  The processed particles that have been pulverized and dried to a particle size of a certain degree or less are discharged to the outside from the discharge port 6 by air by suction by another device, and are processed with a relatively large particle size that is not yet sufficiently pulverized and dried. The particles are not discharged from the discharge port 6, are circulated through the passage body 4 again, and are repeatedly pulverized and dried until the particle size reaches a certain level, and then discharged from the discharge port 6.

  It can be used to treat industrial sludge such as wastewater sludge and food sludge.
