Problems solved by technology

[0004] 1. The pressurization process needs to discharge a large amount of inert gases such as N2, CO2, etc., causing greater environmental pollution;
[0005] 2. The efficiency of the pressurized conveying process is low, and continuous adjustment cannot be realized;
[0006] 3. Pressurized transportation requires high-pressure equipment with large volume and high cost;
[0007] 4. High energy consumption, high requirements on the sealing and pressure resistance of pulverized coal pipeline valves

Embodiment 3

[0046] The operation method of the push rod type pulverized coal pressurized conveying system disclosed in the present invention is as follows:

[0047] Step 1, please refer to figure 2 , figure 2 It is a schematic structural diagram of the push rod type pulverized coal pressurized conveying device in the first working state. The valve 4 on the vent pipe 3 is opened. Under the action of the transmission device 2, the small push rod 14 shrinks to the inside of the large push rod 11, and the large push rod 11 rises to a specific position at the top to stop, open the valve 5, and the atmospheric pressure is stored. The pulverized coal in the tank 1 falls into the shell 10 under the action of gravity. When the pulverized coal falls into the required height, the valve 5 is closed, and the valve 4 is closed at the same time, and the vent pipe 3 is closed;

Abstract

The invention discloses a push rod type pulverized coal pressurizing and conveying device, and a pulverized coal pressurizing and conveying system and method. A normal-pressure storage tank and a high-pressure storage tank are communicated with the push rod type pulverized coal pressurizing and conveying device through a pipeline. A transmission device is in transmission connection with the push rod type pulverized coal pressurizing and conveying device and drives a push rod in the conveying device to move. Pulverized coal falling into the push rod type pulverized coal pressurizing and conveying device is pressurized through the push rod type pulverized coal pressurizing and conveying device and then is conveyed into the high-pressure storage tank. According to the system, no inert gas needs to participate in conveyance, and environmental friendliness is achieved; continuous feeding is achieved by controlling contraction of the push rod, and the feeding quantity is controlled by controlling the contracting frequency of the push rod; the number of pulverized coal pipelines is small, the system is simple, and manufacturing cost is low.
