Description
Technical Field
The invention relates to an intermediate medium gasifier system, and belongs to the technical field of gasifier application.
Background
The natural gas is a green and environment-friendly energy source generally recognized in the world at present, the natural gas is usually in a liquid state and needs to be gasified before being used, at present, the large-scale gasifier in active service in China mainly comprises an open rack gasifier, an immersed combustion type gasifier and an intermediate medium gasifier, and is widely applied as three main gasification equipment of a coastal receiving station in China. The submerged combustion type gasifier is ideal to be applied in low-altitude areas in the north of the Yangtze river, but the submerged combustion type gasifier takes combustion LNG as a heat source, so that large energy is wasted during gasification.
Although the three gasifiers have advantages, the intermediate medium gasifier can utilize cold energy to generate electricity while gasifying, a certain amount of cold energy can be recovered, and the comprehensive operation cost can be further reduced. The method has special position in competition, and is confirmed by the user according to certain advantages. But the application of the method is limited due to the limitation of design conditions. The main problems of IFVs are mainly reflected in three aspects: 1. the lowest design temperature of the originally designed water inlet is lower. 2. The temperature difference between the water inlet and the water outlet is not more than 5 ℃. 3. The water consumption is large, and is about eight thousand tons per hour. The three limitations make the application of IFV in low latitudes and coastal areas difficult at present.
For example: in specific application, the intermediate medium gasifier of the first domestic chemical equipment in China is applied to Zhejiang as water of a heat source, the minimum design temperature is 6.85 ℃, and the temperature difference between an inlet and an outlet is required to be less than 5 ℃ in environmental protection. In the heat exchange calculation, the total heat exchange quantity Q is equal to CM Δ T, when Q is constant, C is a constant, and when Δ T is small, the flow rate M is required to be large. Because of the environmental protection requirement of the actual working condition, the heat transfer temperature difference is smaller and less than 5 degrees, therefore, the water flow of the heat source needs to be very large, and in the practical application, when the gasification amount is 175t/h, the water flow reaches about 8 kilotons per hour. The power consumption of the water pump is large, so that the operation cost is high, and meanwhile, due to the flow, a proper water source is difficult to find in inland.
Therefore, a need exists for a new intermediate medium gasifier system to solve the above problems.

Further, the working temperature range of the intermediate medium gasifier is 20-25 degrees.
Further, the cooling temperature of the cooling water is 0-5 degrees.
In order to solve the problems of increasing the temperature of a water inlet of an intermediate medium gasifier and circulating the temperature so as to expand the limitation of the temperature use range of the intermediate medium gasifier and the use limitation of regions, the invention provides the technical scheme as follows:
furthermore, the IFV preheating water circulation comprises the steps that water enters a reservoir from an inlet pipeline through a water pump and a k2 valve, then inlet water of the reservoir passes through a k1 valve, flows through the interior of the intermediate medium gasifier from an IFV inlet, enters a stable heat source from an IFV outlet for heat exchange, flows back to the IFV inlet of the intermediate medium gasifier through a water return pipeline when the inlet water is heated to the working temperature, the intermediate medium gasifier is started to exchange heat with the inlet water, and cooling water is formed and then flows out of the IFV outlet through the k6 valve.
In order to solve the problem of cooling water circulation refrigeration, the technical scheme is as follows:
furthermore, the refrigeration water circulation of the indoor activity area comprises that cooling water flowing out from the IFV outlet is regulated by a control system, enters the indoor activity area through a k9 valve, exchanges heat with a first fan of the indoor activity area, and then flows back to a stable heat source through a k13 valve.

Detailed Description
In order that the objects, aspects and advantages of the invention will become more apparent, the invention will be described by way of example only, and in connection with the accompanying drawings. It is to be understood that such description is merely illustrative and not intended to limit the scope of the present invention. Moreover, in the following description, descriptions of well-known structures and techniques are omitted so as to not unnecessarily obscure the concepts of the present invention.
The connection mentioned in the present invention is divided into a fixed connection and a detachable connection, the fixed connection (i.e. the non-detachable connection) includes but is not limited to a folding connection, a rivet connection, an adhesive connection, a welding connection, and other conventional fixed connection methods, the detachable connection includes but is not limited to a screw connection, a snap connection, a pin connection, a hinge connection, and other conventional detachment methods, when the specific connection method is not clearly defined, the function can be realized by always finding at least one connection method from the existing connection methods by default, and a person skilled in the art can select the connection method according to needs. For example: the fixed connection selects welding connection, and the detachable connection selects hinge connection.
The first embodiment is as follows: the present embodiment is described with reference to fig. 1-2, and the present embodiment relates to a novel vaporizer system suitable for different latitudes and inland areas, which includes an IFV preheating water cycle, an indoor active area refrigeration water cycle, a freezer refrigeration water cycle, and an enhanced refrigeration water cycle, wherein the IFV preheating water cycle preheats the inlet water of an intermediate medium vaporizer 6, when the inlet water reaches the working temperature of the intermediate medium vaporizer 6, the intermediate medium vaporizer 6 is opened to exchange heat with the inlet water to form cooling water, when the cooling water temperature reaches the cooling temperature, the cooling water after heat exchange flows out from the intermediate medium vaporizer 6, respectively enters the indoor active area refrigeration water cycle and the freezer refrigeration water cycle to exchange heat, and then enters the IFV preheating water cycle, when the cooling water temperature does not reach the cooling temperature, the cooling water after heat exchange flows out from the intermediate medium vaporizer 6 to enter the enhanced refrigeration water cycle to cool, when the cooling water reaches the cooling temperature, the cooling water enters the refrigeration water circulation of the indoor active area and the refrigeration water circulation of the refrigeration house for heat exchange, and then enters the IFV preheating water circulation.
The system utilizes a stable heat source 15 of a power plant, a steel plant and the like near a receiving station to recover waste heat by a heat exchanger 20 and heat cooling water entering an outlet of an intermediate medium gasifier, and the cooling water enters the intermediate medium gasifier from a new place after the temperature of the cooling water is increased. Thus, the limitation of the application range of the intermediate medium gasifier equipment caused by the excessively low inlet temperature is well solved; the whole system only carries out one-time water supplement before starting, and adopts a circulating water structure after starting, and only carries out proper water supplement when necessary, so that heat exchange with larger temperature difference can be carried out, and the problem of environmental pollution caused by the large temperature difference is solved; because the pollution problem does not exist, the temperature difference between the IFV inlet 5 and the IFV outlet can be designed to be larger, the water used as a heat source can be reduced by times, the power of the water pump 23 is greatly reduced, and a large amount of electric energy is saved. The recycling of the heat source with small flow rate makes it possible for large and medium-sized intermediate medium gasifiers to enter inland rivers and inland rivers.
The average annual minimum temperature of water entering the Hai Kong Zhejiang region of Yangtze river is 6.8 ℃ in coastal regions of China. In the area north of the Yangtze river, the annual average minimum temperature of water is less than 6.8 ℃, and is lower and lower, if an intermediate medium gasifier and an open rack gasifier are used, the effect is not ideal, and at present, a submerged combustion type gasifier is mainly used. In order to achieve ideal conditions and operate properly at low design temperature differentials, intermediate media vaporizers and open rack vaporizers must have increased heat source flow. As can be seen from FIG. 2, the smaller the temperature differential at the IFV inlet 5, the greater the water flow required.
The increase of the water flow and the flow can increase the power of the water pump, which wastes larger electric energy, therefore, the increase of the flow to ensure the heat exchange amount is not economical, and causes larger energy waste. Therefore, how to get rid of the limitation of small temperature difference and inlet temperature needs to be considered, and the flow of water is reduced while the same heat is transferred, so that the aim of reducing the comprehensive operation cost is fulfilled.
The IFV preheating water circulation comprises the steps that water enters a reservoir 2 from an inlet pipeline 24 through a water pump 23 and a k2 valve 3, then inlet water of the reservoir 2 passes through a k1 valve 1, flows through the interior of an intermediate medium gasifier 6 from an IFV inlet 5, enters a stable heat source 15 from an IFV outlet 8 for heat exchange, flows back to the IFV inlet 5 of the intermediate medium gasifier 6 through a water return pipeline 19 when the inlet water is heated to the working temperature, the intermediate medium gasifier 6 is started to exchange heat with the inlet water, and cooling water flows out of the IFV outlet 8 through a k6 valve 10 after being formed.
When the temperature of inlet water is lower than the working temperature of the intermediate medium gasifier 6, the inlet water enters the system, the intermediate medium gasifier 6 is not started firstly, the inlet water directly enters the IFV preheating water circulation after flowing into the intermediate medium gasifier 6, and the inlet water heated and heated flows back to the IFV inlet 5 after the IFV preheating water circulation heating circulation. The water temperature of the reflux can be calculated and set through the heat exchange of the heating system, and the intermediate medium gasifier 6 gasification system is started after the water temperature reaches the design temperature of the inlet of the intermediate medium gasifier 6, so that the intermediate medium gasifier 6 can be normally used.
The indoor activity area refrigeration water circulation comprises that cooling water flowing out of an IFV outlet 8 enters an indoor activity area 18 through a k9 valve 25 under the regulation of a control system 7, and flows back to a stable heat source 15 through a k13 valve 26 after exchanging heat with a first fan 17 of the indoor activity area 18.
The refrigeration water circulation of the refrigeration house comprises that cooling water flowing out from an IFV outlet 8 is regulated by a control system 7, enters the refrigeration house 16 through a k8 valve 13, exchanges heat with a second fan 14 of the refrigeration house 16, and flows back to a stable heat source 15 through a k13 valve 26.
The reinforced refrigeration water circulation comprises that cooling water flowing out from an IFV outlet 8 is regulated through a control system 7, enters a heat exchanger 20 through a k5 valve 9, and enters an indoor active region refrigeration water circulation and/or a refrigeration house refrigeration water circulation for heat exchange through a k11 valve 11 when the temperature in the heat exchanger 20 is reduced to a cooling temperature.
The working temperature range of the intermediate medium gasifier 6 is 20-25 degrees.
The cooling temperature of the cooling water is 0-5 degrees.
The IFV inlet 5 is provided with a K3 valve 4, the water return pipeline 19 is provided with a K12 valve 22, the inlet pipeline 24 is provided with a K10 valve 21, and the water inlet of the stable heat source 15 is provided with a K7 valve 12.
During the specific design, the temperature difference of the IFV outlet 8 is increased, and the formula shows that: when we improve Δ T, the flow M can be reduced under the condition that the total heat exchange amount is not changed, so we can not only use the intermediate medium gasifier 6 normally, but also reduce the water usage, and through calculation, if the water heat transfer temperature difference is increased to 25 degrees by heating from 6.8 degrees which is normally designed, the temperature of the hot gas outlet is set to 2 degrees, the flow of water can be reduced by times, as can be seen by the formula: power P of the water pump, W × 2.72 × h η, power P being proportional to flow W, how many times flow W decreases, and how many times power P of the pump decreases. For example: when 5 temperature of IFV entry by the 25 degrees that 6.8 degrees rose, the flow of heat source water can significantly reduce, calculates according to the 1000KW of the water pump of original design, and 10 equipment can practice thrift the electric energy every year, and concrete calculation step is as follows:
1. calculate according to the 1000KW of the water pump of original design, 6 can practice thrift the electric energy annually in 1 intermediate medium vaporizer:
(1-1800/7550) 1000kw 24 h 365 day 876 ten thousand yuan renowned currency.
2. At one end of the IFV outlet 8, the electrical power saved due to refrigeration is:
the refrigerating capacity is 300W/m2。
5000 square meters of cold energy required by an indoor activity area or a refrigeration house: 300W/m2*5000m2＝1500KW
The system is expected to save electricity annually:
1500(KW) × 8 (hr) × 21 days/month 5 ═ 1260000KW · h
The system is expected to be cost-effective annually:
1.0 yuan/degree 1260000KW · h 126 ten thousand yuan
3. On the material: if the circulating water can be softened and treated, the heat exchange tube of the intermediate medium gasifier 6 can be made of stainless steel or treated carbon steel, so that the one-time investment can be further saved:
13.4 ton (17-3.2) ten thousand yuan/ton 184 ten thousand yuan/table
Therefore, each equipment can save more than one thousand yuan each year.
The use method of the novel gasifier system suitable for different latitudes and inland comprises the following steps:
all valves are in a closed state before the system is started, namely a k1 valve 1, a k2 valve 3, a k3 valve 4, a k5 valve 9, a k6 valve 10, a k7 valve 12, a k8 valve 13, a k9 valve 25, a k10 valve 21, a k11 valve 11, a k12 valve 22 and a k13 valve 26;
