Problems solved by technology
[0007] However, when such a chemical delivery method is adopted, for the deliverer, since the tank body 13 that is limited in capacity and weight is used to transport the chemical solution that is dissolved in warm water and the volume increases, it is different from the case of only transporting the chemical. In contrast, while the transport efficiency per unit of chemicals decreases, there is also the possibility that when the temperature of the aqueous solution during transport decreases (for example, 10°C), the aqueous solution becomes supersaturated and crystallization occurs
Therefore, especially when the chemical M is delivered in a cold region, the delivery time cannot be too long, so that there is a problem that the range of the delivery area is limited.
[0008] Correspondingly, for the recipient user, there is an advantage of not requiring equipment such as storage and dissolution of the chemical M, and a full-time operator for the operation, but there is a problem that the delivery unit price of the chemical M is high.

The invention provides a safe and efficient method for transporting a powdered chemical from a storage house of a supplier to a chemical receiving place of a user, and for quickly dissolving the chemical to deliver. The method includes a step S1 of storing the chemical in a bag body with the predetermined weight of the chemical which is kept in a storage house; a step S2 of supplying the number of bag bodies into a tank truck for keeping the chemical in the tank in the powder form with the bags opened; a step S3 of transporting the chemical to the chemical receiving place of the user by a tank truck; a step S4 of supplying a solvent and steam at the receiving place for mixing and dissolving the chemical, or a step of S4 A of supplying a solvent to the tank by a tank provided at the receiving place for storing and dissolving, for dissolving the chemical by mixing and cycling; and a step S5 of supplying the dissolved chemical solution to the storage tank of the user.
Description
Technical field [0001] The present invention relates to a method of transporting chemicals, and more specifically to the safe and effective transportation of powdered chemicals used by solvent dissolution from the storage warehouse of the consignor to the receiving place of the user, and the chemicals are quickly dissolved It is a chemical delivery method that completes delivery after reaching the specified solution concentration. Background technique [0002] As an example of the powder chemicals used by solvent dissolution as described above, sodium chlorate used as an oxidative bleaching agent for bleaching pulp in a paper mill can be mentioned. [0003] In the past, as a method of transporting the sodium chlorate (hereinafter referred to as "chemicals") to paper mills and other manufacturers (hereinafter referred to as "users"), the general operating sequence is as shown in FIG. 21. Containers 1 such as bags containing the prescribed weight of chemical M are stored in the dan...
