Problems solved by technology

[0002] The method of operating the existing thermal hydrolysis system for organic matter does not have specific storage procedures, but relies on manual operation or operator experience, so it cannot be linked with various sensors to effectively open and close pumps and valves. Therefore, there are It takes a lot of work time and the problem of lower digestion efficiency
[0003] In addition, the waste energy generated in the reaction tank for thermally hydrolyzing sludge cannot be effectively used, so there is a problem of excessive energy required for operation.
[0004] In addition, effective digestion cannot be performed, and there is a problem that many dehydrated cakes are generated when sludge is dehydrated after digestion.
[0005] Since the waste heat continuously generated in the cogeneration unit cannot be effectively utilized, waste heat is often wasted and not utilized. In particular, the organic matter thermal hydrolysis system required for sludge treatment cannot be coordinated with the cogeneration unit. the problem of effectively using

Embodiment approach

[0039] A specific embodiment of the invention is observed based on the drawings.

[0040] According to an embodiment of the present invention, it is divided into figure 1 Applied to the run method in Figure 2 to Figure 4 The operation method of the organic matter thermal hydrolysis system and for the Figure 5 Applied to the run method in Figure 2 to Figure 4 The operating method of the thermal hydrolysis system for organic matter is described.

[0041] Figure 1 to Figure 4 What is shown and described is the operation method when a reaction tank is installed between the adjustment tank and the dissolution tank. Figure 5 of the running method Figure 6 to Figure 12 What is illustrated and described is the operation method when two or more reaction tanks are installed between the adjustment tank and the dissolution tank.

[0042] The purpose of the present invention is to improve the digestion efficiency of sludge and improve the dehydration property after digestion, t...

Embodiment 1

[0059] based on figure 2 Observe Example 1 according to the invention.

[0060] exist figure 1 In the thermal hydrolysis system for organic matter, the sludge supply pump 1-6 is equipped to operate, and the hopper load cell 7-1 installed at the lower end of the hopper is used to continuously measure the weight of the injected sludge while feeding the sludge to the hopper through the conveying pipeline. This is a step of transferring sludge equivalent to the set amount and stopping the operation of the sludge supply pump.

[0061] The amount of sludge injected into the hopper is measured by the hopper load cell 7-1 provided at the lower part of the hopper, and the amount of sludge corresponding to the amount set in the PLC is sent to the hopper. As for the amount of sludge injected and stored in the hopper, it is desirable that the set amount is 5 times to 10 times the amount of sludge treated at one time by the reaction tank which is the core configuration of the present in...

Embodiment 2

[0076] based on image 3 The operating method is observed according to Example 2 of the present invention.

[0077] exist figure 1 The thermal hydrolysis system for organic matter includes operating the sludge supply pump 1-6, and using the hopper load cell 7-1 arranged at the lower end of the hopper to continuously measure the weight of the injected sludge while transporting it to the hopper with the set one. A step in which a certain amount of sludge is equivalent and the operation of the sludge supply pump is stopped.

[0078] The load cell installed at the lower part of the hopper is linked with the sludge supply pump to continuously measure the amount of sludge injected into the hopper with the load cell, and inject the sludge equivalent to the amount set in the PLC or microcomputer. In terms of the amount of sludge injected and stored in the hopper, it is desirable to set the amount between 5 and 10 times the amount of sludge that is processed at one time in the reacti...
