[0002] The general box type submerged combustion gasifier abroad is transported to the customer end, and then installed and debugged at the customer end. This traditional installation method wastes a lot of installation and debugging time and energy of the engineering personnel at the customer end, the equipment occupies a large area, and the quality of the site construction is uncontrollable, so that the overall quality and efficiency of the box type submerged combustion gasifier cannot meet the requirements of the customer.

[0003] The utility model patent CN209782233U provides a submerged combustion gasifier, which provides an integrated installation scheme. The combustion chamber, flue gas pipeline, water tank, gasification pipeline, water supply pipeline and chimney are fixed and installed. The box type submerged combustion gasifier can be precisely assembled and whole machine debugged in the manufacturing factory.

Only the connection of the pipeline is needed to realize the work of the box type submerged combustion gasifier. This installation method makes the working condition of the box type submerged combustion gasifier more stable, greatly shortens the delivery cycle, and realizes the ability of using the product as soon as it is landed.

[0004] However, in actual use, parts such as the combustion chamber, backwater pipeline and chimney cannot be guaranteed stable during transportation. In practice, they are still disassembled and shipped as parts. Installation and debugging are still needed at the customer site. On the other hand, in the process of use, maintenance personnel cannot maintain the gasifier under harsh external weather conditions. The gasifier is not safe and beautiful during transportation to the customer. SUMMARY

[0005] The technical scheme of the present application provides a box type submerged combustion gasifier, which solves the problems of convenient carrying and transportation of parts, and whole installation of parts shipped separately. The technical scheme is as follows:

[0006] The application provides a box-type submerged combustion gasifier, which comprises a burner, a furnace, a flue gas pipeline, a water tank, a heat exchange pipeline and a water vapor discharge port, a compensation section is arranged between the water vapor discharge port and the water tank, one end of the compensation section is communicated with the water tank, the other end of the compensation section is communicated with the water vapor discharge port, the box-type submerged combustion gasifier further comprises an upper box and a lower box, the burner and the furnace are located in the upper box, the flue gas pipeline, the water tank and the heat exchange pipeline are located in the lower box, the water vapor discharge port is arranged in the upper box and communicates with the outside through the top of the upper box, a support is arranged in the lower box and opposite to the water vapor discharge port, the upper box and the lower box are connected through a twist lock, and the lower box and a base mounting surface are connected through the twist lock.

[0007] The upper box and the lower box are arranged, so that the whole gasifier can be wrapped in the upper box and the lower box, on the one hand, the appearance of the gasifier is beautiful and convenient to carry, and on the other hand, the commonly used components in the gasifier are no longer exposed to the air, contact with the external environment is avoided, and the service life of the exposed components is prolonged.

[0008] The twist lock is arranged, so that the upper box and the lower box can be quickly connected and disassembled, and the lower box and the base mounting surface can also be quickly mounted through the twist lock, the mounting time of the product at the client end and the disassembly time during maintenance are greatly shortened.

[0009] The support is arranged, so that the sundries coming in through the water vapor discharge port are abutted at the support position and cannot directly enter the water tank, the cleanness and safe operation of the equipment are ensured.

[0010] In particular, a partition plate is arranged on the side of the lower box relative to the water tank, a circulating pump is arranged between the partition plate and the lower box, one end of the circulating pump is communicated with the bottom of the water tank through a pipeline, and the other end of the circulating pump is communicated with the shell of the furnace through a pipeline.

[0011] The partition plate is arranged, so that the circulating pump can be placed in a relatively dry environment, avoiding working in water, and under the protection of the lower box, the circulating pump can be not affected by rain and low temperature, and the working noise can be reduced.

[0012] The circulating pump is arranged, so that the water in the water tank can be stirred under the driving of the circulating pump, and the water temperature of the water tank is kept uniform.

[0013] In particular, a support is arranged between the partition plate and the lower box.

[0014] Specifically, a spiral water channel is further arranged between the shell of the furnace and the furnace, the spiral water channel is configured to make the liquid pumped out by the circulating pump spiral around the outer wall of the furnace, and the tail of the spiral water channel is connected with the water tank through a connecting pipe.

[0015] The water in the water tank can be driven by the circulating pump to circulate around the outside of the hearth to cool the hearth, and the high-temperature water for cooling the hearth can return to the water tank through the connecting pipe, so that the heat can be fully utilized.

[0016] Specifically, at least two temperature sensors are arranged on the connecting pipe, and the temperature sensors are electrically connected with the circulating pump.

[0017] Through the arrangement of the at least two temperature sensors, the specific temperature of the water entering the water tank through the connecting pipe can be known first. Then the flow of the circulating pump can be controlled in real time. When the liquid temperature is low, the flow of the circulating pump is reduced, and when the liquid temperature is high, the flow of the circulating pump is increased, so that the water temperature flowing into the water tank is maintained within a certain range.

[0018] Specifically, the end of the compensation section close to the water tank is provided with a gas-liquid separator.

[0019] Through the arrangement of the gas-liquid separator, the water vapor evaporated from the water tank can be blocked and returned to the liquid under the action of the gas-liquid separator, realizing the recovery of liquid heat and ensuring the purity of exhaust gas. Therefore, the gasifier will not appear a large amount of condensed mist sprayed from the water vapor discharge port in a low temperature environment, avoiding the influence on the environment.

[0020] In particular, the top end of the water vapor discharge port is provided with a lightning rod and a bird repeller.

[0021] Through the arrangement of the lightning rod, the water vapor discharge port is prevented from being struck by lightning, so that the gasifier is not damaged. Through the arrangement of the bird repeller, birds are prevented from nesting and excreting in the water vapor discharge port because of their preference for the temperature of the water vapor discharge port. Nesting will affect the discharge efficiency of the water vapor discharge port, and the excrement of birds is corrosive, which will cause damage to the water vapor discharge port over a long period of time.

[0022] In particular, a first inspection opening is formed in the support, a second inspection opening is formed in the side surface of the upper box body, and a staircase is arranged on the lower box body corresponding to the second inspection opening.

[0023] Through the arrangement of the first inspection opening, the maintenance personnel can regularly clean the sundries in the support. Through the arrangement of the second inspection opening, the maintenance personnel can directly maintain and repair the burner and other components in the upper box body, avoiding the maintenance of the maintenance personnel in bad weather, speeding up the maintenance efficiency and ensuring the personal safety of the maintenance personnel.

[0024] Specifically, at least two water mist nozzles are arranged on the inner wall of the hearth, and the water mist nozzles are connected with the spiral water channel.

[0025] Through the arrangement of the water mist nozzles, the inside of the hearth can be cooled when the temperature of the hearth is high, the generation of nitrogen oxides is inhibited, the emission is guaranteed to meet the standard, and the environment is protected.

[0026] Specifically, the heat exchange pipe is detachably mounted on the water tank, the compensation section is detachably mounted on the water tank, the water vapor discharge port is detachably connected to the bracket, and the vertical flue gas pipe consists of two detachable pipe sections.

[0027] Through the above-mentioned detachable manner, the entire gasifier is easy to disassemble and install at the upper and lower levels.

However, it will be apparent to those skilled in the art that the application can be practiced without these specific details. In some instances, well-known structures and functions have not been described in detail in order to avoid obscuring aspects of the application.

[0038] The current submerged combustion gasifier cannot guarantee the stability of components such as burners, return water pipes and chimneys during transportation. In actual use, the components are still disassembled and shipped as spare parts, and installation and debugging are still required at the customer site. On the other hand, maintenance personnel cannot repair the gasifier in the case of severe external weather conditions, and the gasifier is not safe and beautiful during transportation to the customer.

[0039] In order to solve the problem of convenient carrying and transportation, and the problem that spare parts cannot be integrally installed on the ground, the technical scheme of the present application provides a box type submerged combustion gasifier and a monitoring system thereof.

[0040] The following will be described in detail according to the accompanying Figures 1 to 6 The application will be further described in detail.

[0041] As Figures 1 to 6 As shown in the figure, the present application provides a box type submerged combustion gasifier, which comprises a burner 3, a hearth 4, a flue gas pipeline, a water tank, a heat exchange pipeline 5 and a water vapor discharge port 6. A compensation section 7 is arranged between the water vapor discharge port 6 and the water tank. One end of the compensation section 7 is in communication with the water tank, and the other end of the compensation section 7 is in communication with the water vapor discharge port 6. The box type submerged combustion gasifier further comprises an upper box 1 and a lower box 2. The burner 3 and the hearth 4 are located in the upper box 1. The flue gas pipeline, the water tank and the heat exchange pipeline 5 are located in the lower box 2. The water vapor discharge port 6 is arranged in the upper box 1 and penetrates the top of the upper box 1 to communicate with the outside. A support 9 is arranged in the lower box 2 relative to the water vapor discharge port 6. The upper box 1 and the lower box 2 are connected by a twist lock 8. The lower box 2 and the base mounting surface are connected by a twist lock 8.

[0042] Through the arrangement of the upper box 1 and the lower box 2, the entire gasifier can be wrapped in the upper box 1 and the lower box 2. On the one hand, the appearance of the gasifier is beautiful and convenient to carry, and at the same time, the commonly used components in the gasifier are no longer exposed to the air, avoiding contact with the external environment, prolonging the service life of the exposed components.

[0043] In actual use, the upper box 1 and the lower box 2 are arranged as simple and easily accessible containers.

[0044] The upper box body 1 and the lower box body 2 can be quickly connected and detached through the setting of the twist lock 8, and the lower box body 2 and the base mounting surface can also be quickly installed through the twist lock 8, which greatly shortens the installation time of the product at the customer end and the disassembly time during maintenance.

[0045] Through the setting of the support 9, the sundries coming in through the water vapor discharge port 6 will not directly enter the water tank at the position of the support 9, which ensures the clean and safe operation of the equipment.

[0046] In particular, the lower box body 2 is provided with a partition plate 11 relative to the side of the water tank, and a circulating pump 10 is arranged between the partition plate 11 and the lower box body 2. One end of the circulating pump 10 is communicated with the bottom of the water tank through a pipeline, and the other end of the circulating pump 10 is communicated with the shell of the hearth 4 through a pipeline.

[0047] Through the setting of the partition plate 11, the circulating pump 10 can be placed in a relatively dry environment to avoid working in water, and under the protection of the lower box body 2, the circulating pump 10 can be not affected by rain and low temperature, and the working noise can be reduced.

[0048] Through the setting of the circulating pump 10, the water in the water tank can be stirred under the driving of the circulating pump 10, so that the water temperature of the water tank is kept uniform.

[0049] In particular, the lower box body 2 is provided with a partition plate 11 relative to the side of the water tank, and a support 9 is arranged between the partition plate 11 and the lower box body 2.

[0050] Specifically, a spiral water channel 12 is further arranged between the shell of the hearth 4 and the hearth 4, and the spiral water channel 12 is configured to make the liquid pumped out by the circulating pump 10 spiral around the outer wall of the hearth 4. The tail of the spiral water channel 12 is connected with the water tank through a connecting pipe 21.

[0051] Through the setting of the spiral water channel 12 and the circulating pump 10, the water in the water tank can be circulated around the outside of the hearth 4 under the driving of the circulating pump 10 to cool the hearth 4. The high-temperature water for cooling the hearth 4 can also return to the water tank through the connecting pipe 21, so that the heat can be fully utilized.

[0052] Specifically, at least two temperature sensors 13 are arranged on the connecting pipe 21, and the temperature sensors 13 are electrically connected with the circulating pump 10.

[0053] Through the setting of the at least two temperature sensors 13, the specific temperature of the water entering the water tank through the connecting pipe 21 can be known first. Then the flow of the circulating pump 10 can be controlled in real time. When the liquid temperature is low, the flow of the circulating pump 10 is reduced, and when the liquid temperature is high, the flow of the circulating pump 10 is increased, so that the water temperature flowing into the water tank is maintained within a certain range.

[0054] Specifically, the compensation section 7 is provided with a gas-liquid separator 14 at one end close to the water tank.

[0055] The gas-liquid separator 14 is provided to block the return flow of liquid under the action of the gas-liquid separator 14, so that the water vapor evaporated from the water tank can be recovered, and the purity of the exhaust gas is ensured, so that the gasifier will not appear a large amount of condensed mist spray at the water vapor discharge port 6 in a low temperature environment, avoiding the influence on the environment.

[0056] In actual use, the gas-liquid separator 14 can be a baffling separation, a cyclone separation or a packed separation.

[0057] In particular, the water vapor discharge port 6 is provided with a lightning rod 15 and a bird repeller 16 at the top end.

[0058] Through the setting of the lightning rod 15, the water vapor discharge port 6 is prevented from being struck by lightning, so that the gasifier is not damaged, and through the setting of the bird repeller 16, birds are prevented from nesting and excreting in the water vapor discharge port because of their preference for the temperature of the water vapor discharge port. Nesting will affect the discharge efficiency of the water vapor discharge port 6, and the excrement of birds is corrosive and will cause damage to the water vapor discharge port 6 over a long period of time. Under the requirements of cost control and stability, a wind-driven bird repeller 16 is generally used.

[0059] In order to facilitate maintenance, a first access hole 17 is formed in the support 9, a second access hole 18 is formed in the side surface of the upper tank body 1, and a staircase 19 is arranged on the lower tank body 2 corresponding to the second access hole 18.

[0060] Through the setting of the first access hole 17, the maintenance personnel can regularly clean the sundries in the support 9, and through the setting of the second access hole 18, the maintenance personnel can directly maintain and repair the components such as the burner 3 in the upper tank body 1, avoiding the maintenance personnel to maintain in bad weather, speeding up the maintenance efficiency and ensuring the personal safety of the maintenance personnel.

[0061] Specifically, at least two water mist nozzles 20 are arranged on the inner wall of the hearth 4, and the water mist nozzles 20 are connected with the spiral water channel 12.

[0062] In this embodiment, eight water mist nozzles 20 are used, which are arranged on the inner wall of the hearth 4 at equal intervals and follow the spiral water channel 12, so that the water mist nozzles 20 can obtain water source from the spiral water channel 12.

[0063] Through the setting of the water mist nozzles 20, the temperature inside the hearth 4 can be lowered when the temperature is high, the generation of nitrogen oxides is inhibited, the emission is ensured to meet the standard, and the environment is protected.

[0064] Specifically, the heat exchange pipe 5 is detachably mounted on the water tank, the compensation section 7 is detachably mounted on the water tank, the water vapor discharge port 6 is detachably connected to the bracket, and the vertical flue gas pipe is composed of two detachable pipe sections.

[0065] The above-mentioned detachable manner makes it easy to disassemble and install the upper and lower layers of the entire gasifier, and the detachable installation actually adopted is flange installation.
