High Pressure Forced Circulation Boiler

High Pressure Forced Circulation Boiler

Condensate recovery high pressure forced circulation boiler of Embodiment 1, how the recovery boiler steam condensate recovery system recovering exhaust system high-temperature condensed water, the condensed water can maximize the use of heat, water conservation, fuel economy. Condensate recovery system can be divided into open and closed recovery system recovery system. Recovery system is open to a condensate recovery tank to the boiler, the condensed water recovery and utilization in the process, one end of the recovery pipe is open to the atmosphere, i.e., the condensed water collection tank is open to the atmosphere. When the lower pressure of the condensed water, can not be reached by the pressure from recycling properties, high temperature condensed water pump pressure-feeding. The advantage of this system is that the device is simple, easy to operate, a small initial investment; however, a large area of ​​the system, resulting in low economic efficiency, larger environmental pollution, and since the condensed water is directly in contact with the atmosphere, dissolved oxygen concentration in the condensed water improved, easy to produce equipment corrosion. This system is suitable for small vapor supply systems, a small amount of condensate, small amounts of secondary steam system. When using this system should minimize emissions of secondary steam. Condensate recovery system is a closed tank and all piping are set at constant pressure, the system is closed. Condensate system has most of the energy recovery through a certain recovery device directly to the boiler, the condensed water recovery temperature loss in the cooling portion of the pipe network only, since closed, quality assurance, the water reduces the cost of recovery into the boiler . The advantage is economic good condensate recovery, long working life of the equipment, but the system is relatively large initial investment, operation inconvenient. 2. Select recovery methods for different condensate reconstruction project, which way the recovery and recycling equipment selection, is whether the project can achieve the purpose of investment crucial step. First, we must accurately grasp the condensed water condensate recovery system, if the condensed water is not calculated correctly, will make the condensate pipe diameter selected too large or too small. Second, to properly control the pressure and temperature of the condensed water, which embodiment uses the recovery system, which device, how to arrange the pipe network, the condensate temperature and pressure are related. Third, the trap condensate recovery system is selected to be noted that the content, wrong trap selection, will affect the pressure and temperature at which condensation water use, also affect the normal operation of the recovery system. Recovery efficiency is not as high as possible in the system selection, but also consider economic issues, that is considered waste heat utilization efficiency, we must also consider the initial investment. Due to the high efficiency of closed recovery system, less environmental pollution, are often preferred.

It is understood that in order to successfully promote the transformation and development of traditional coal chemical industry, January 1, 2019, letter to the Office of Henan Province workers released a special action program (hereinafter referred to as the "Program"), to promote pollution prevention campaign of Henan Province, three-year action implementation of the scheme, to speed up the traditional coal chemical industry (ammonia, methanol) industry green transformation, to achieve high-quality development. "Program" details are as follows.

First, the key tasks

1, and strictly control new capacity. Adherence to the red line capacity, traditional coal chemical enterprises prohibit new construction, new capacity expansion projects alone, is strictly prohibited without permission around the building does not meet the requirements of the industrial layout plan of coal chemical project in principle. The province's coal chemical projects and intensive clean-up, but according to the specified time limit has been approved to start construction of the project in principle, to construction, relocation and renovation projects must be upgraded into the base or campus planning. By 2020, the chemical industry out of the fixed bed coal gasifier intermittent exit single set of devices 300,000 tons / year of synthetic ammonia production capacity.

2, increase the relocation and reconstruction efforts. Further promote the densely populated towns of dangerous chemicals production enterprises and urban built-up areas heavily polluting industrial relocation of enterprises, the implementation of an intensive investigation, the establishment of management accounting, according to "a business a policy" during mode classification advance. Priority to promoting the urban area of ​​coal chemical industry relocation, conversion or quit, not in the urban area but not in the business park to gradually move the park, according to the specified execution be discontinued or phased out. Close to exit the business to achieve the "two off three clear" (cut industrial water, electricity, removal of raw materials, products, production equipment), in situ transformation of the company to implement the upgrading of the standard industry benchmark, off-site relocation of enterprises to According to large-scale, modern principles move into the province for involving chemical industry gathering area.

3, Green transformation. Before the end of 2019, coal chemical enterprises fully completed VOCs governance. And comprehensively promote the chemical industry equipment static and dynamic sealing points, storage, handling, waste water systems, unorganized process emissions and non-normal operating conditions and other root causes of remediation. In accordance with national requirements, the timely completion of the coal chemical industry waste discharge permit issued by the work, companies must comply with the behavior of the sewage discharge permit clear conditions, various types of environmental inspection found violations, strictly and severely investigated and dealt with as soon as possible in place.

Second, the organization and implementation

1, roles and responsibilities. Relevant provincial jurisdiction over municipal government on the development of local coal chemical industry restructuring and overall responsibility, strengthen organizational leadership, with local conditions, the development of coal chemical industry restructuring and development program implementation, implementation tasks initiatives. Coal chemical industry is the main responsibility for the implementation of the restructuring and development, to strictly implement the main responsibility for production safety and environmental protection, the implementation of the relocation of the green transformation. Provincial Industry and Information Technology Department, Development and Reform Commission, the ecological environment, the Office of Emergency Management and other provincial departments according to the division of responsibilities, strengthen guidance and improve relevant policies and measures.

2, strictly implement the policy. Comprehensive use of market mechanisms, economic instruments, legal and necessary administrative means to approach, to promote enterprise restructuring and development. Strict implementation of China's industrial policy, strictly enforce the standards of environmental protection, quality, energy consumption, safety and technology. Relocation and reconstruction of urban population centers dangerous chemicals production enterprises and urban built-up area of ​​relocation and reconstruction project focused on heavy polluting industrial enterprises, shall be given support in terms of fiscal policy, tax incentives, financial support, land policies.

3, strengthen supervision and accountability. Strengthen supervision of new capacity alone, without approval of the establishment of Chemical Industry Park, unauthorized implementation does not meet the industrial layout planning requirements of coal chemical projects, in violation of the registration and management of hazardous chemicals and construction projects "three simultaneous" (also designed, constructed, and concurrent use of illegal activities) system, etc., must be severely accountable accountability.
