Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a production facility for synthetic oil containing vegetable activated carbon, and in particular, to an auxiliary combustion equipment containing vegetable activated carbon, which is a raw material for synthetic oil containing vegetable activated carbon. This invention relates to a device that delivers a predetermined amount of additive material.

[Conventional technology]

Water-in-oil emulsion fuel, which is a mixture of fuel oil, water and an emulsifier, has been widely known due to the demand for low NOX and to improve combustion efficiency, but there are great expectations in terms of improving combustion efficiency. I couldn't get it. Therefore, the present inventor attempted to improve the combustion efficiency by adding a combustion improver such as pulverized coal to this emulsion fuel, but the effect was not sufficient.

Then, as a result of various studies,
It has been found that by adding a predetermined amount of a combustion supporting additive produced by adding vegetable activated carbon to the emulsion fuel as described in No. 6987, the combustion efficiency can be improved almost as expected.

Then, it is necessary to mix a predetermined amount of the tar-like combustion-supporting additive containing the vegetable activated carbon in a small range into emulsified water and liquid fuel such as heavy oil. This was done by pumping the water up with a pump.

[Problem that the invention attempts to solve]

However, pumping out the tar-like combustion additive using a metered cup is a very primitive method, which is time-consuming and inefficient, and it also has the problem of staining the clothes of the workers and the surrounding environment. The dot was hot.

In addition, the method of pumping up the tar-like combustion additive by driving the pump for a predetermined period of time requires the use of a small pump because the amount is small, and the combustion additive contains about 300 mesh of activated carbon. There were problems in that it was easy to get clogged and it was difficult to pump up a certain amount of combustion-supporting additive. Therefore, it is necessary to attach a pressure gauge to the pump and drive the pump for a certain period of time while checking that the pressure gauge is always constant, but this time the pipe connecting to the pressure gauge is clogged with activated carbon and cannot be used accurately. However, it has been extremely difficult to repeatedly deliver a tar-like combustion additive in a fixed amount in order to achieve automation.

The present invention was developed in view of these circumstances, and is a method for producing synthetic oil containing vegetable activated carbon, which has a device that can reliably deliver a fixed amount of tar-like combustion additives containing vegetable activated carbon. The purpose is to provide facilities.

[Means to solve problems]

The production equipment for synthetic oil containing vegetable activated carbon according to the present invention in accordance with the above purpose includes a device for delivering a tar-like combustion additive containing a predetermined amount of vegetable activated carbon, and a predetermined amount of emulsified water made of water and an emulsifier. a device for sending out a predetermined amount of liquid fuel made of heavy oil, etc., a device for stirring and mixing the predetermined amount of the sent-out combustion support additive, emulsified water, and liquid fuel, and a device for stirring and mixing the agitated and mixed liquid fuel. The equipment for producing synthetic oil containing vegetable activated carbon includes an emulsion device, and the device for delivering the predetermined amount of the combustion supporting additive containing the vegetable activated carbon is installed above the stirring and mixing device. a rapid-acting motor-operated valve, such as an electric ball valve or an electric butterfly valve, connected to the lower part of the container for the combustion-supporting additive; and a timer control device that issues a signal to open the operating motor-operated valve for a certain period of time, and a certain amount of the combustion-assisting additive is placed in the container containing the combustion-assisting additive;
By opening the rapid-acting motor-operated valve for a predetermined period of time, a straight pipe-like flow path is formed, and a certain amount of the combustion-supporting additive is delivered to the stirring and mixing device at the bottom without causing clogging.

Here, a rapid-acting motor-operated valve refers to a solenoid valve that opens and closes rapidly in response to an electric signal. For example, even if the valve is rapidly opened and closed by a motor or a cylinder via a solenoid valve, good.

[Effect]

Next, the operation of the synthetic oil manufacturing equipment containing vegetable activated carbon of the present invention will be explained.

First, a predetermined amount of a tar-like combustion aid additive containing vegetable activated carbon is placed in a container, and a rapid-acting motor-operated valve connected to the bottom is opened for a predetermined time by a timer control device to supply it to the stirring and mixing device. . As a result, the opening passage of a quick-acting electric valve such as an electric ball valve or an electric butterfly valve opens wide from the inlet to the outlet, forming a straight pipe shape. The tar-like combustion-assisting additive flows out without clogging, and the tar-like combustion-assisting additive containing a predetermined amount of vegetable activated carbon is sent to the stirring and mixing device at the bottom under the pressure of the liquid at the top. After this, the valve of the rapid-acting motor-operated valve closes rapidly after a certain period of time in response to a signal from the timer control device, so the flow of the tar-like combustion additive material stops, but at this time too, it operates rapidly and closes, so No clogging of additives occurs.

At the same time, a predetermined amount of emulsified water and a predetermined amount of liquid fuel made of heavy oil or the like are supplied to the stirring and mixing device for the combustion-supporting additive, emulsified water, and liquid fuel.

Thereafter, the stirring and mixing device is driven to mix these combustion supporting additives, emulsified water, and liquid fuel, and feed the mixture to an emulsion device, which emulsifies the mixture and produces the desired synthetic oil. do.
