By adjusting the pressure regulating valve 31, it is possible to adjust the flow area of, for example, the conveying fluid medium in the first conduit 12, thereby changing the pressure at the cocatalyst container inlet 111 and thus the cocatalyst conveying pressure in the cocatalyst container 11. The measure belongs to indirect control of the delivery pressure of the cocatalyst, and is convenient to carry out and easy to control.
In one embodiment shown in FIG. 1, a steady-pressure nitrogen gas delivered from a fluid power source via a first conduit 12 is delivered to the promoter container 11 from the promoter container inlet 111 and the promoter contained in the promoter container 11 is delivered to the catalyst reduction system under the pressure of the steady-pressure nitrogen gas. When the cocatalyst is in the form of, for example, a slurry of an aluminum alkyl, the cocatalyst temperature and the steady-pressure nitrogen gas pressure have a very significant effect on the cocatalyst transport when it is fed to the catalyst reduction system. Therefore, in order to ensure the activity of the cocatalyst and to ensure that the slurry cocatalyst is not solidified, the cocatalyst is subjected to heat preservation.

Preferably, the temperature control unit 2 comprises an incubator 21; the cocatalyst container 11 is disposed in the incubator 21. The temperature of the cocatalyst container 11 can be stabilized by providing the incubator 21.
Further preferably, the heat insulation box 21 includes a heat insulation lining disposed inside the wall of the heat insulation box 21, and the co-catalyst in the co-catalyst container 11 can be better kept in a stable temperature range by disposing the heat insulation lining, so as to improve the transportation stability of the co-catalyst.

In a second aspect, the invention provides a cocatalyst delivery method for delivering the cocatalyst to a point of use using a fluid power source; the method includes controlling the delivery stability of the cocatalyst by controlling the temperature of the cocatalyst and the delivery pressure of the cocatalyst to the site of use. By controlling the temperature of the cocatalyst, the activity of the cocatalyst can be ensured, and the physical state of the cocatalyst can also be ensured, for example, when the cocatalyst is in a slurry state, the slurry can be kept at a set viscosity by controlling the temperature, thereby being beneficial to conveying. When the physical state of the catalyst is stable, the amount of the cocatalyst which is transferred from the cocatalyst container per unit time can be ensured to be stable by controlling the transfer pressure of the cocatalyst to the place of use. In one embodiment shown in fig. 1, the cocatalyst is contained in a cocatalyst container 11, and one end of the cocatalyst container 11 is communicated with a fluid power source of nitrogen gas with pressure stabilization; the other end of the cocatalyst vessel 11 leads to the place of use; the temperature of the cocatalyst contained in cocatalyst container 11 is controlled by controlling the temperature of cocatalyst container 11; the stability of the delivery of the cocatalyst is controlled by controlling the cocatalyst output pressure at the cocatalyst vessel outlet 112.
Preferably, an insulating fluid is used to control the temperature of the cocatalyst. By adopting the method, the heat circulation can be carried out through the circulating fluid, thereby achieving the purpose of heat preservation.

The method has low heat preservation cost, for example, the heat preservation fluid can adopt high-temperature waste water in production.
Preferably, the temperature of the cocatalyst is controlled by controlling the flow rate of the insulating fluid. This control is very convenient. As shown in fig. 1, the temperature of the incubator 21 can be controlled by controlling the flow rate of the incubation tube from the side of the incubator inlet 211 into the incubator 21, for example, when the temperature of the incubator 21 is too high, the flow rate of the incubation fluid flowing into the incubator 21 through the incubation tube is reduced; when the temperature in the incubator 21 is too low, the flow rate of the insulating fluid flowing into the incubator 21 through the insulating pipe is increased, thereby changing the temperature of the incubator 21 and thus adjusting the temperature of the cocatalyst.
Preferably, the method comprises controlling the delivery pressure by controlling a fluid pressure of the fluid power source. By providing a back pressure to the cocatalyst to be conveyed in the cocatalyst conveying unit 1 by means of a fluid power source, the cocatalyst is moved by the back pressure and further conveyed to a downstream place of use. The method for controlling the conveying stability of the cocatalyst can be implemented more easily in technical terms by controlling the conveying pressure of the cocatalyst and keeping the fluctuation of the conveying force within a set range, and can effectively prevent the discontinuous phenomenon of cocatalyst conveying and improve the conveying stability of the cocatalyst.
For ease of control, it is preferred that control of the delivery pressure of the cocatalyst to the point of use is achieved by controlling the pressure of the delivery fluid medium into the cocatalyst vessel.
The fluid power source adopts a fluid conveying medium, which is not only beneficial to ensuring the activity of the cocatalyst, but also beneficial to improving the safety. Further preferably, nitrogen is used as the transport fluid medium. Thus, the production cost can be greatly reduced.
In one embodiment, as shown in FIG. 1, where the site of use is a catalyst reduction system, the promoter is contained in a promoter container 11, utilizing the method, on the one hand, to employ control of the pressure of the fluid power source at promoter container inlet 111; thus, by controlling the cocatalyst pressure within a predetermined range, it is possible to avoid an excessively large or small output of the cocatalyst.

Therefore, the temperature of the cocatalyst is controlled within a set range, so that the reduction of the activity of the cocatalyst caused by overhigh temperature of the cocatalyst is avoided; the second aspect avoids the problem that the co-catalyst delivery fluctuation is large or interrupted due to the fact that the viscosity of the co-catalyst is too high when the temperature is too low.

as shown in fig. 1: the cocatalyst container 11 is a cocatalyst steel cylinder in which the cocatalyst is accommodated, the cocatalyst moves from the cocatalyst container inlet 111 side to the cocatalyst container outlet 112 side by the push of a pressure-stabilized nitrogen gas having a certain pressure supplied from the first pipe 12, and then the cocatalyst is supplied from the cocatalyst container outlet 112 to the catalyst reduction system through the second pipe 13 under the pressure supplied by the nitrogen gas. In order to improve the transport stability of the cocatalyst, the cocatalyst is temperature-controlled by the temperature control unit 2. In order to convey the cocatalyst out of the catalyst steel cylinder as much as possible, one end of the second pipeline 13 close to the cocatalyst steel cylinder extends into the cocatalyst steel cylinder through the cocatalyst container outlet 112 until the end abuts against the lowest position of the inner wall of the cocatalyst steel cylinder, in order to ensure that the cocatalyst can be emptied as much as possible and the output speed is not influenced, a groove structure is cut at one end part of the second pipeline 13 far into the cocatalyst steel cylinder by utilizing a cross section which forms an angle of 30-60 degrees with the axis of the second pipeline 13, and when the auxiliary device is used, the lowest end of the groove abuts against the lowest point of the inner wall of the cocatalyst steel cylinder.
