Description

Technical Field

[0001] The utility model relates to the technical field of coking equipment, in particular to a heat storage cooler and an environmental dust removal ground station with the heat storage cooler. Background Art

[0002] The CDQ process requires a supporting environmental dust removal station. Existing environmental dust removal stations consist of dust removal ducts, a thermal storage cooler, a pulse bag filter, a dust removal fan, a muffler, an ash bin, a chimney, and ash cleaning and conveying equipment.

[0003] Specifically, in the dry quenching equipment, on the inlet side of the thermal storage cooler, the high-temperature dust removal pipe and the low-temperature dust removal pipe are respectively connected to the two inlets of the thermal storage cooler; on the outlet side of the thermal storage cooler, a pulse bag dust collector and a dust removal fan and other devices are connected in sequence, among which the dust removal fan is located at the end of the pipeline of the environmental dust removal ground station.

[0004] The high-temperature flue gas in the high-temperature dust removal pipe and the low-temperature flue gas in the low-temperature dust removal pipe flow into the thermal storage cooler through the inlet of the thermal storage cooler under the suction action of the dust removal fan, and are mixed and cooled inside the thermal storage cooler so that the temperature of the mixed flue gas reaches the allowable temperature of the pulse bag dust collector.

[0005] However, since the high-temperature flue gas and low-temperature flue gas generated by the dry quenching system are both discontinuous and paroxysmal, the flue gas after the high-temperature flue gas and the low-temperature flue gas are mixed in the heat storage cooler is difficult to reduce to the expected temperature. In this case, when the mixed flue gas that has not been reduced to the expected temperature flows into the pulse bag dust collector, the temperature of the mixed flue gas may exceed the fire resistance limit of the pulse bag dust collector bag, causing damage to the pulse bag dust collector.

DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field based on this application are within the scope of protection of the present invention.

[0033] The present invention provides a heat storage cooler. Figure 1 As shown, Figure 1 This is a schematic diagram of the structure of the thermal storage cooler provided by the present invention. The thermal storage cooler comprises: a heat exchange chamber 1, with a thermal storage cooler outlet 11 disposed on one side of the heat exchange chamber 1, which communicates with an outlet pipe 2 via a straight outlet pipe section 111; an air inlet 12 disposed on the sidewall of the straight outlet pipe section 111; an air intake pipe 3, one end of which communicates with the straight outlet pipe section 111 of the heat exchange chamber 1 via the air inlet 12, and the other end of which communicates with the external environment; and at least two thermal storage cooler inlets 13 disposed on the other side of the heat exchange chamber 1.

[0034] In this embodiment, an air inlet 12 is provided on the side wall of the outlet straight pipe section 111, and the air intake pipe 3 is connected to the air inlet 12 by welding. One end of the air intake pipe 3 is connected to the outlet straight pipe section 111 of the heat storage cooler through the air inlet 12, and the other end is connected to the external environment.

[0035] During the production process, flue gases from the high-temperature dust removal duct 41 and the low-temperature dust removal duct 42 enter the heat exchange chamber 1 through the thermal storage cooler inlet 13, where heat exchange occurs. If heat exchange is insufficient, the high-temperature mixed flue gases enter the thermal storage cooler outlet 11 through the straight outlet pipe section 111. At this point, the air intake pipe 3 uses negative pressure to draw in air from the outside environment. This outside air passes through the air intake pipe 3 and enters the thermal storage cooler outlet straight pipe section 111, recooling the mixed flue gases exiting the thermal storage cooler outlet 11 to a temperature acceptable for the pulse bag filter (not shown). The recooled mixed flue gases flow through the outlet pipe 2 into the pulse bag filter.

[0036] In some implementations of the present invention, such as Figure 1 The heat storage cooler further comprises: a valve 31 , which is arranged at any position on the air intake pipe 3 and is used to control the outside air from entering the outlet straight pipe section 111 .

[0037] In this embodiment, a valve 31 is provided on the air intake pipe 3. During the production process, personnel can monitor the temperature of the thermal storage cooler outlet 11 using a temperature measuring instrument. When the mixed flue gas flowing out of the thermal storage cooler outlet 11 exceeds the allowable temperature of the pulse bag filter, personnel control the valve 31 to open, allowing outside air to enter the outlet straight pipe section 111 through the air intake pipe 3, recooling the high-temperature mixed flue gas to the allowable temperature of the pulse bag filter.

[0038] When the mixed flue gas flowing out of the heat storage cooler outlet 11 meets the allowable temperature of the pulse bag dust collector, the staff controls the valve 31 to close. At this time, it is difficult for the outside air to enter the outlet straight pipe section 111 through the air suction pipe 3, thereby reducing the energy consumption of the fan.

[0039] In some implementations of the present invention, such as Figure 1 The valve 31 is an electric valve. The thermal storage cooler further comprises a temperature sensor 32, which is disposed at the thermal storage cooler outlet 11 and is electrically connected to the electric valve.

[0040] In this embodiment, valve 31 can be an electric valve electrically connected to a temperature sensor 32, which monitors the temperature of the thermal storage cooler outlet 11 in real time. When the temperature sensor 32 detects that the mixed flue gas flowing out of the thermal storage cooler outlet 11 is higher than the permissible temperature of the pulse bag filter, the temperature sensor 32 controls the electric valve to open, allowing outside air to enter the outlet straight pipe section 111 through the air intake pipe 3, further cooling the high-temperature mixed flue gas to the permissible temperature of the pulse bag filter.

[0041] When the temperature sensor 32 detects that the temperature of the mixed flue gas flowing out of the heat storage cooler outlet 11 meets the allowable temperature of the pulse bag dust collector, the temperature sensor 32 controls the valve 31 to close. At this time, it is difficult for outside air to enter the outlet straight pipe section 111 through the air intake pipe 3, thereby reducing the energy consumption of the dust removal fan 6.

[0042] Under the coordinated action of the temperature sensor 32 and the electric valve, the temperature of the mixed flue gas is automatically adjusted, which reduces the steps of manual adjustment and can timely control the temperature of the mixed flue gas, thus avoiding the problem of pulse bag dust collector burning caused by untimely temperature measurement.

[0043] In some embodiments of the present invention, the air intake pipe 3 is a straight pipe, and the length of the air intake pipe 3 is 900 mm to 1300 mm.

[0044] In this embodiment, the air intake pipe 3 is a straight pipe with a length of 900 mm to 1300 mm, which shortens the air flow distance. This reduces the resistance along the air flow, reduces the power requirement of the dust removal fan 6, and reduces the energy consumption of the dust removal fan 6.

[0045] Also, see Figure 1 Since the length of the air intake pipe 3 is 900mm-1300mm, the open end of the air intake pipe 3 is close to the outlet straight pipe section 111, and there is no need to set it on the ground during the installation process, so that the air intake pipe 3 is located as a whole near the heat exchange chamber 1, reducing the equipment footprint and the construction workload during installation, and reducing the cost of ground setting and construction.

[0046] In some implementations of the present invention, such as Figure 1 and Figure 2 As shown, Figure 2 This is a schematic diagram of the structure of the thermal storage cooler provided by the present invention using an elbow pipe. When the end of the air intake pipe 3 connected to the outside environment extends away from the ground, the air intake pipe 3 is sequentially provided with a muffler 33 and a rain cap 34 along the air inlet 12 toward the end connected to the outside environment. Alternatively, the air intake pipe 3 is sequentially provided with a muffler 33 and an elbow pipe 35 along the air inlet 12 toward the open end of the air intake pipe 3.

[0047] In this embodiment, a muffler 33 is provided on the air intake pipe 3 to reduce the noise during the air intake process. A rain cap 34 is provided on the side of the air intake pipe 3 that is connected to the external environment to effectively prevent water from entering the interior of the device along the air intake pipe 3 and causing adverse effects. Figure 2 , the elbow pipe 35 can also be used as a waterproof device.

[0048] In some implementations of the present invention, such as Figure 3 As shown, Figure 3 This is a schematic diagram of the structure of the thermal storage cooler provided by the present invention, with the air intake pipe extending toward the ground along the air inlet. When the end of the air intake pipe 3, which communicates with the outside environment, extends toward the ground, a muffler 33 is provided on one side of the air intake pipe 3, which is located along the air inlet 12 and toward the end of the air intake pipe 3 connected to the outside environment.

[0049] In this embodiment, the end of the air intake pipe 3 that communicates with the outside environment can also extend toward the ground. In this case, since the open end of the air intake pipe 3 faces the ground, moisture can be prevented from entering the device. Therefore, the design of the rain cap 34 or the elbow pipe 35 can be eliminated.

[0050] In some implementations of the present invention, such as Figures 1 to 3As shown, the heat storage cooler further includes: an explosion relief valve 5 ; the explosion relief valve 5 is arranged on the side wall of the heat exchange chamber 1 .

[0051] In this embodiment, an explosion relief valve 5 is provided on the side wall of the heat exchange chamber 1 , which can effectively reduce the pressure in the heat exchange chamber 1 .

[0052] The utility model also provides an environmental dust removal ground station, such as Figure 4 and Figure 5 As shown, Figure 4 This is a schematic diagram of the structure of the environmental dust removal ground station provided by the utility model; Figure 5 for Figure 4 Schematic diagram of the structure of the thermal storage cooler. This environmental dust removal ground station includes: a thermal storage cooler according to any of the above-mentioned embodiments, a high-temperature dust removal duct 41, and a low-temperature dust removal duct 42; each thermal storage cooler inlet 13 is connected to a high-temperature dust removal duct 41 or a low-temperature dust removal duct 42; the thermal storage cooler is in communication with at least one high-temperature dust removal duct 41 and at least one low-temperature dust removal duct 42; a connecting duct 43 is provided between the high-temperature dust removal duct 41 and the low-temperature dust removal duct 42; a dust removal fan 6 is located at the end of the pipeline on the thermal storage cooler outlet side; and an ash hopper 7, with the thermal storage cooler placed above the ash hopper 7.

[0053] In this embodiment, the dust removal fan 6 located at the end of the pipeline on the outlet side of the thermal storage cooler provides power. Under the action of suction, the flue gas in the high-temperature dust removal duct 41 and the low-temperature dust removal duct 42 enters the heat exchange chamber 1 through the thermal storage cooler inlet 13, and heat exchange occurs in the heat exchange chamber 1. When the heat exchange is insufficient, the high-temperature mixed flue gas enters the outlet straight pipe section 111 through the thermal storage cooler outlet 11. At this time, the air intake pipe 3 uses negative pressure to inhale air from the external environment. The external air passes through the air intake pipe 3 and enters the outlet straight pipe section 111 of the thermal storage cooler, and recools the mixed flue gas flowing out of the thermal storage cooler outlet 11 to reduce the temperature of the mixed flue gas to the allowable temperature of the pulse bag dust collector.

[0054] Since the air intake pipe 3 is relatively short, the open end of the air intake pipe 3 is close to the outlet straight pipe section 111 during installation, so that the entire air intake pipe 3 is located near the heat exchange chamber 1. This effectively avoids the problem of the air intake pipe 3 being too long and requiring it to be installed on the ground, which would increase the floor space and make construction difficult. It also reduces the costs incurred by the excessive floor space and complex construction process.

[0055] At the same time, the thermal storage cooler is installed above the ash hopper 7, and the dust below the thermal storage cooler is collected by the ash hopper, which reduces environmental pollution.

[0056] The above description is only a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention are included in the scope of protection of the present invention.
